AB Beef trim, the primary component of ground beef, is tested by both the Food Safety and Inspection Service (FSIS) and meat packers for Escherichia coli O157:H7 under a zero tolerance standard. We compare and contrast the process control and filtering roles of this testing on costs and food safety outcomes. Both of these roles of testing have been alternatively emphasized in recent legislative proposals and policy statements on beef trim testing. In the process control role, test design - including the decisions to increase sample sizes, re-test lots, and change tolerance thresholds - only affects the cost of implementing a targeted food safety standard, but does not directly affect health outcomes. In contrast, in the filtering role, test design influences the likelihood of errors and directly affects health outcomes. Neither role eliminates all risk from this pathogen. More broadly, we discuss the incentives food producers face to increase their frequency of testing and improve food safety processes in response to positive test findings as the process control role emphasizes.

AB Riparian canopy removal and land use may introduce multiple stressors that can alter food and habitat for stream organisms, but the influence of these alterations on macroinvertebrate colonization dynamics is less well known. A field study involving the simultaneous placement and removal of artificial substrates was performed to examine how macroinvertebrate colonization rates might vary with algal accumulation within a perennial stream segment in eastern Ohio, USA. The study was conducted over a 60-day summer colonization period in three reaches that were selected to represent an algal resource gradient according to canopy cover and agricultural nutrient sources in the riparian corridor. Total nitrogen, water temperatures, and mean algal biomass from substrates increased along the resource gradient represented by the study sites. Total macroinvertebrate biomass and the abundance and biomass of scrapers also increased according to the gradient. Correlation results indicated that chlorophyll a biomass, rather than time or temperature, was better related to the abundance and biomass of most primary consumers on substrates. These results suggest that the combined effects of elevated temperatures and nutrients can result in relatively rapid algal accrual that may alter the colonization and establishment of macroinvertebrate communities in streams subjected to gradients of riparian disturbances.

AB No-tillage is looked upon by many as a way to enable sustainable cropping intensification to meet future agricultural demands. Although no-tillage suggests merely the absence of tillage, in reality several components need to be applied to a conservation agriculture system to guarantee equal or higher yields and better environmental performance than with conventional tillage systems. No-tillage/conservation agriculture systems research has now been performed for more than half a century in many countries around the world, primarily for economic reasons, but also to reduce labour and energy consumption and improve environmental outcomes. However, an integrated approach to understanding this system requires standardized research methodology based on site-specific conditions. We contend that broad understanding is lacking of what conservation agriculture systems research means. This has led to a situation of conflicting research results because different technologies, methodologies, and definitions of conservation agriculture systems have been applied. The term no-tillage has been used despite considerable soil movement in the previous crop, to inject fertilizer or to establish the current crop. Similarly, the term no-tillage has been used for systems with very little or no crop mulch cover, extended fallow periods, alternating tillage and no-tillage, or crops grown in monoculture. By not performing no-tillage research in a systems approach, many problems can be encountered such as reduced yields, high erosion, low infiltration, elevated fertilizer and high pesticide use. Materials and methods in an experiment are often not descriptive enough to unveil peculiarities. By analysing the function of components of conservation agriculture systems in monofactorial experiments, synergetic interactions among components can be overlooked. In this editorial, we discuss the need to thoroughly describe materials and methods to avoid confusing interpretations of results. We contend that standardization of research methodologies in no-tillage/conservation agriculture systems is needed based on a thorough description of the whole system so that results from different researchers and regions of the world can be logically compared.

ID RHEOLOGICAL PROPERTIES; MATHEMATICAL-MODEL; FRUIT CUTICLES; SKIN; GUM;

AB This study investigated the viscoelastic characteristics of tomato skins subjected to conventional hot lye peeling and emerging infrared-dry peeling by using dynamic mechanical analysis (DMA). Three DMA testing modes, including temperature ramp, frequency sweep, and creep behavior test, were conducted to evaluate the transition temperatures and dynamic moduli of tomato peels heated by infrared radiation and hot lye at four heating durations (30, 45, 60, and 75 s). Fresh tomato peels were used as a control. Results showed that dynamic moduli of tomato peels were sensitive to temperature ramp and frequency sweep tests. Over a temperature range from 20 degrees C to 100 degrees C, transition temperatures of infrared treated peels (63-72 degrees C) and lye treated peels (43-75 degrees C) were significantly lower than those of fresh control (similar to 88 degrees C). Values of both storage and loss moduli of infrared heated peels were considerably higher than those of the fresh control, whereas values of the storage and loss moduli from the lye peeled samples were lower than those of fresh peels. DMA tests effectively differentiated the viscoelastic behaviors of tomato peels and indicated mechanistic differences between the lye peeling and infrared dry-peeling. (C) 2013 Elsevier Ltd.

AB Solenopsis invicta virus 3 (SINV-3) is a positive-sense single-stranded RNA virus that infects the red imported fire ant, Solenopsis invicta. We show that the second open reading frame (ORF) of the dicistronic genome is expressed via a frameshifting mechanism and that the sequences encoding the structural proteins map to both ORF2 and the 3' end of ORF1, downstream of the sequence that encodes the RNA-dependent RNA polymerase. The genome organization and structural protein expression strategy resemble those of Acyrthosiphon pisum virus (APV), an aphid virus. The capsid protein that is encoded by the 3' end of ORF1 in SINV-3 and APV is predicted to have a jelly-roll fold similar to the capsid proteins of picornaviruses and caliciviruses. The capsid-extension protein that is produced by frameshifting, includes the jelly-roll fold domain encoded by ORF1 as its N-terminus, while the C-terminus encoded by the 5' half of ORF2 has no clear homology with other viral structural proteins. A third protein, encoded by the 3' half of ORF2, is associated with purified virions at substoichiometric ratios. Although the structural proteins can be translated from the genomic RNA, we show that SINV-3 also produces a subgenomic RNA encoding the structural proteins. Circumstantial evidence suggests that APV may also produce such a subgenomic RNA. Both SINV-3 and APV are unclassified picorna-like viruses distantly related to members of the order Picornavirales and the family Caliciviridae. Within this grouping, features of the genome organization and capsid domain structure of SINV-3 and APV appear more similar to caliciviruses, perhaps suggesting the basis for a "Calicivirales" order.

AB Little is known about the taxonomic diversity of cyanobacteria in deserts, despite their important ecological roles in these ecosystems. In this study, cyanobacterial strains from the Atacama, Colorado, and Mojave Deserts were isolated and characterized using molecular, morphological, and ecological information. Phylogenetic placement of these strains was revealed through Bayesian and parsimony-based phylogenetic analyses utilizing sequences of the 16S rRNA gene and the associated 16S-23S ITS region. Based on the combined evidence of this polyphasic approach, a new species from desert soils morphologically corresponding to the genus Trichocoleus was described. Trichocoleus desertorum sp. nov. Muhlsteinova, Johansen et Pietrasiak was used to obtain a phylogenetic reference point for Trichocoleus, a genus so far characterized by morphological description only. Through characterization of this new taxon in desert soils we hope to contribute to the general understanding of cyanobacterial diversity in extreme arid habitats.

AB BACKGROUND
Liquid extracts from pomegranate peel have the potential for use as natural antioxidant products. This study investigates the quality changes of liquid extracts before and after thermal treatment during sterilization and storage. Liquid pomegranate peel extracts were prepared, sterilized under ultra-high temperature (UHT) at 121 degrees C for 10 s and then stored at three temperatures (4, 25 and 37 degrees C) for up to 180 days. The industrial, color, UV-visible spectrum profile and antioxidant (phenolics) characteristics were measured.
RESULTS
Thermal sterilization treatment had no negative effects on the industrial, color, spectral and antioxidant characteristics of the extracts. After 180 days, the extracts stored at 4 degrees C retained 67% of the initial total soluble phenolic content and 58% of the original scavenging activity. The major antioxidant components in the extracts (stored at 4 degrees C for 180 days) were gallic acid, punicalagin A, punicalagin B and ellagic acid having concentrations of 19.3, 197.2, 221.1 and 92.4 mg L-1, respectively.
CONCLUSION
The results show that liquid pomegranate peel extracts had acceptable thermal stability after sterilization and storage. The recommended storage condition of this product was low temperature. (c) 2013 Society of Chemical Industry

AB Background: As it becomes increasingly possible to obtain DNA sequences of orthologous genes from diverse sets of taxa, species trees are frequently being inferred from multilocus data. However, the behavior of many methods for performing this inference has remained largely unexplored. Some methods have been proven to be consistent given certain evolutionary models, whereas others rely on criteria that, although appropriate for many parameter values, have peculiar zones of the parameter space in which they fail to converge on the correct estimate as data sets increase in size.
Results: Here, using North American pines, we empirically evaluate the behavior of 24 strategies for species tree inference using three alternative outgroups (72 strategies total). The data consist of 120 individuals sampled in eight ingroup species from subsection Strobus and three outgroup species from subsection Gerardianae, spanning similar to 47 kilobases of sequence at 121 loci. Each "strategy" for inferring species trees consists of three features: a species tree construction method, a gene tree inference method, and a choice of outgroup. We use multivariate analysis techniques such as principal components analysis and hierarchical clustering to identify tree characteristics that are robustly observed across strategies, as well as to identify groups of strategies that produce trees with similar features. We find that strategies that construct species trees using only topological information cluster together and that strategies that use additional non-topological information (e. g., branch lengths) also cluster together. Strategies that utilize more than one individual within a species to infer gene trees tend to produce estimates of species trees that contain clades present in trees estimated by other strategies. Strategies that use the minimize-deep-coalescences criterion to construct species trees tend to produce species tree estimates that contain clades that are not present in trees estimated by the Concatenation, RTC, SMRT, STAR, and STEAC methods, and that in general are more balanced than those inferred by these other strategies.
Conclusions: When constructing a species tree from a multilocus set of sequences, our observations provide a basis for interpreting differences in species tree estimates obtained via different approaches that have a two-stage structure in common, one step for gene tree estimation and a second step for species tree estimation. The methods explored here employ a number of distinct features of the data, and our analysis suggests that recovery of the same results from multiple methods that tend to differ in their patterns of inference can be a valuable tool for obtaining reliable estimates.

AB Culicoides biting midges (Diptera: Ceratopogonidae) are a major vector group responsible for the biological transmission of a wide variety of globally significant arboviruses, including bluetongue virus (BTV). In this review we examine current biological resources for the study of this genus, with an emphasis on detailing the history of extant colonies and cell lines derived from C sonorensis, the major vector of BTV in the USA. We then discuss the rapidly developing area of genomic and transcriptomic analyses of biological processes in vectors and introduce the newly formed Culicoides Genomics and Transcriptomics Alliance. Preliminary results from these fields are detailed and finally likely areas of future research are discussed from an entomological perspective describing limitations in our understanding of Culicoides biology that may impede progress in these areas.

AB "Candidatus Liberibacter solanacearum'' (Lso) is an economically important pathogen of solanaceous crops and the putative causal agent of zebra chip disease of potato (Solanum tuberosum L.). This pathogen is transmitted to solanaceous species by the potato psyllid, Bactericera cockerelli (Sulc), but many aspects of the acquisition and transmission processes have yet to be elucidated. The present study was conducted to assess the interacting effects of acquisition access period, incubation period, and host plant on Lso titer in psyllids, the movement of Lso from the alimentary canal to the salivary glands of the insect, and the ability of psyllids to transmit Lso to non-infected host plants. Following initial pathogen acquisition, the probability of Lso presence in the alimentary canal remained constant from 0 to 3 weeks, but the probability of Lso being present in the salivary glands increased with increasing incubation period. Lso copy numbers in psyllids peaked two weeks after the initial pathogen acquisition and psyllids were capable of transmitting Lso to non-infected host plants only after a two-week incubation period. Psyllid infectivity was associated with colonization of insect salivary glands by Lso and with Lso copy numbers >10,000 per psyllid. Results of our study indicate that Lso requires a two-week latent period in potato psyllids and suggest that acquisition and transmission of Lso by psyllids follows a pattern consistent with a propagative, circulative, and persistent mode of transmission.

AB Sweetpotato, commercially grown in over 100 countries, is one of the ten most important staple crops in the world. Sweetpotato weevil is a major pest of sweetpotato in most areas of cultivation, the feeding of which induces production in the sweetpotato root of extremely bitter tasting and toxic sesquiterpenes which can render the sweetpotato unfit for consumption. A significant step towards improved management of this weevil species was the identification of a female-produced sex pheromone [(Z)-3-dodecenyl (E)-2-butenoate] to which males are highly attracted. Reported here are results of research that documents a nearly 5-fold increase in male sweetpotato weevil catch in traps baited with this pheromone and a green light provided by a solar-powered, light-emitting diode (LED). The combination of olfactory and night-visible visual cues significantly enhanced trap effectiveness for this nighttime-active insect species. These results provide promise for improved sweetpotato weevil detection and suppression in mass trapping programs.

AB There is a general lack of knowledge regarding the absorption and tissue storage of the provitamin A carotenoid beta-cryptoxanthin. The present study investigated the whole-body tissue distribution of beta-cryptoxanthin in an appropriate small animal model, the Mongolian gerbil (Meriones unguiculatus), for human provitamin A carotenoid metabolism. After 5d of carotenoid depletion, five gerbils were euthanised for baseline measurements. The remaining gerbils were placed in three weight-matched treatment groups (n 8). All the groups received 20 mu g/d of beta-cryptoxanthin from tangerine concentrate, while the second and third groups received an additional 20 and 40 mu g/d of pure beta-cryptoxanthin (CX40 and CX60), respectively, for 21d. During the last 2d of the study, urine and faecal samples of two gerbils from each treatment group were collected. beta-Cryptoxanthin was detected in the whole blood, and in twelve of the fourteen tissues analysed. Most tissues resembled the liver, in which the concentrations of beta-cryptoxanthin were significantly higher in the CX60 (17 center dot 8 (sem 0 center dot 7)mu g/organ; P=0 center dot 004) and CX40 (16 center dot 2 (sem 0 center dot 9)mu g/organ; P=0 center dot 006) groups than in the CX20 group (13 center dot 3 (sem 0 center dot 4)mu g/organ). However, in intestinal tissues, the concentrations of beta-cryptoxanthin increased only in the CX60 group. Despite elevated vitamin A concentrations in tissues at baseline due to pre-study diets containing high levels of vitamin A, beta-cryptoxanthin maintained those vitamin A stores. These results indicate that beta-cryptoxanthin is stored in many tissues, potentially suggesting that its functions are widespread.

AB Innate immunity relies on the perception of pathogen-associated molecular patterns (PAMPs) by pattern-recognition receptors (PRRs) located on the host cell's surface. Many plant PRRs are kinases. Here, we report that the Arabidopsis receptor kinase EF-TU RECEPTOR (EFR), which perceives the elf18 peptide derived from bacterial elongation factor Tu, is activated upon ligand binding by phosphorylation on its tyrosine residues. Phosphorylation of a single tyrosine residue, Y836, is required for activation of EFR and downstream immunity to the phytopathogenic bacterium Pseudomonas syringae. A tyrosine phosphatase, HopAO1, secreted by P. syringae, reduces EFR phosphorylation and prevents subsequent immune responses. Thus, host and pathogen compete to take control of PRR tyrosine phosphorylation used to initiate antibacterial immunity.

AB Extensive research has been conducted on cold acclimation and freezing tolerance of fall-sown cereal plants due to their economic importance; however, little has been reported on the biochemical changes occurring over time after the freezing conditions are replaced by conditions favorable for recovery and growth such as would occur during spring. In this study, GC-MS was used to detect metabolic changes in the overwintering crown tissue of oat (Avena sativa L.) during a fourteen day time-course after freezing. Metabolomic analysis revealed increases in most amino acids, particularly proline, 5-oxoproline and arginine, which increased greatly in crowns that were frozen compared to controls and correlated very significantly with days after freezing. In contrast, sugar and sugar related metabolites were little changed by freezing, except sucrose and fructose which decreased dramatically. In frozen tissue all TCA cycle metabolites, especially citrate and malate, decreased in relation to unfrozen tissue. Alterations in some amino acid pools after freezing were similar to those observed in cold acclimation whereas most changes in sugar pools after freezing were not. These similarities and differences suggest that there are common as well as unique genetic mechanisms between these two environmental conditions that are crucial to the winter survival of plants.

AB A currently utilized pre-harvest biocontrol method involves field inoculations with non-aflatoxigenic Aspergillus flavus strains, a tactic shown to strategically suppress native aflatoxin-producing strains and effectively decrease aflatoxin contamination in corn. The present in situ study focuses on tracking the invasion and colonization of an aflatoxigenic A. flavus strain (AF70), labeled with green fluorescent protein (GFP), in the presence of a non-aflatoxigenic A. flavus biocontrol strain (AF36), to better understand the competitive interaction between these two strains in seed tissue of corn (Zea mays). Corn kernels that had been co-inoculated with GFP-labeled AF70 and wild-type AF36 were cross-sectioned and observed under UV and blue light to determine the outcome of competition between these strains. After imaging, all kernels were analyzed for aflatoxin levels. There appeared to be a population difference between the co-inoculated AF70-GFP+AF36 and the individual AF70-GFP tests, both visually and with pixel count analysis. The G FP allowed us to observe that AF70-GFP inside the kernels was suppressed up to 82% when co-inoculated with AF36 indicating that AF36 inhibited progression of AF70-GFP. This was in agreement with images taken of whole kernels where AF36 exhibited a more robust external growth compared to AF70-GFP. The suppressed growth of AF70-GFP was reflected in a corresponding (upto 73%) suppression in aflatoxin levels. Our results indicate that the decrease in aflatoxin production correlated with population depression of the aflatoxigenic fungus by the biocontrol strain supporting the theory of competitive exclusion through robust propagation and fast colonization by the non-aflatoxigenic fungus.

AB Background: Our objective was to determine if a biofortified variety of black bean can provide more bioavailable-iron (Fe) than a standard variety. Two lines of black beans (Phaseolus-vulgaris L.), a standard (DOR500; 59 mu g Fe/g) and biofortified (MIB465; 88 mu g Fe/g) were used. The DOR500 is a common commercial variety, and the MIB465 is a line developed for higher-Fe content. Given the high prevalence of Fe-deficiency anemia worldwide, it is important to determine if Fe-biofortified black beans can provide more absorbable-Fe.
Methods: Black bean based diets were formulated to meet the nutrient requirements for the broiler (Gallus-gallus) except for Fe (dietary Fe-concentrations were 39.4 +/- 0.2 and 52.9 +/- 0.9 mg/kg diet, standard vs. biofortified, respectively). Birds (n=14) were fed the diets for 6-weeks. Hemoglobin-(Hb), liver-ferritin and Fe-related transporter/enzyme gene-expression were measured. Hemoglobin-maintenance-efficiency and total-body-Hb-Fe values were used to estimate Fe-bioavailability.
Results: Hemoglobin-maintenance-efficiency values were higher (P<0.05) in the group consuming the standard-Fe beans on days 14, 21 and 28; indicating a compensatory response to lower dietary-Fe. Final total-Hb-Fe body content was higher in the biofortified vs. the standard group (26.6 +/- 0.9 and 24.4 +/- 0.8 mg, respectively; P<0.05). There were no differences in liver-ferritin or in expression of DMT-1, Dcyt-B, and ferroportin. In-vitro Fe-bioavailability assessment indicated very low Fe-bioavailability from both diets and between the two bean varieties (P>0.05). Such extremely-low in-vitro Fe-bioavailability measurement is indicative of the presence of high levels of polyphenolic-compounds that may inhibit Fe-absorption. High levels of these compounds would be expected in the black bean seed-coats.
Conclusions: The parameters of Fe-status measured in this study indicate that only a minor increase in absorbable-Fe was achieved with the higher-Fe beans. The results also raise the possibility that breeding for increased Fe-concentration elevated the levels of polyphenolic-compounds that can reduce bean Fe-bioavailability, although the higher levels of polyphenolics in the higher-Fe beans may simply be coincidental or an environmental effect. Regardless, Fe-biofortified beans remain a promising vehicle for increasing intakes of bioavailable-Fe in human populations that consume high levels of these beans as a dietary staple, and the bean polyphenol profile must be further evaluated and modified if possible in order to improve the nutritional quality of higher-Fe beans.

AB Globalization has increased the potential for the introduction and spread of novel pathogens over large spatial scales necessitating continental-scale disease models to guide emergency preparedness. Livestock disease spread models, such as those for the 2001 foot-and-mouth disease (FMD) epidemic in the United Kingdom, represent some of the best case studies of large-scale disease spread. However, generalization of these models to explore disease outcomes in other systems, such as the United States's cattle industry, has been hampered by differences in system size and complexity and the absence of suitable livestock movement data. Here, a unique database of US cattle shipments allows estimation of synthetic movement networks that inform a near-continental scale disease model of a potential FMD-like (i.e., rapidly spreading) epidemic in US cattle. The largest epidemics may affect over one-third of the US and 120,000 cattle premises, but cattle movement restrictions from infected counties, as opposed to national movement moratoriums, are found to effectively contain outbreaks. Slow detection or weak compliance may necessitate more severe state-level bans for similar control. Such results highlight the role of large-scale disease models in emergency preparedness, particularly for systems lacking comprehensive movement and outbreak data, and the need to rapidly implement multi-scale contingency plans during a potential US outbreak.

AB A simple and efficient flow injection mass spectrometric (FIMS) method was developed to differentiate cinnamon (Cinnamomum) bark (CB) samples of the four major species (C. burmannii, C. verum, C. aromaticum, and C. loureiroi) of cinnamon. Fifty cinnamon samples collected from China, Vietnam, Indonesia, and Sri Lanka were studied using the developed FIMS fingerprinting method. The FIMS fingerprints of the cinnamon samples were analyzed using principal component analysis (PCA). The FIMS technique required only 1 min of analysis time per sample. The representative samples from each of the four major species of cinnamon were further examined using an ultrahigh-performance liquid chromatography high-resolution mass spectrometry system, and the chemical differences between the four species were profiled. The results showed that the 1 min FIMS fingerprinting method successfully differentiated the four cinnamon species studied.

AB Glyceollin-related metabolites produced in rats following oral glyceollin administration were screened in plasma, feces, and urine, and these metabolites were identified by precursor and product ion scanning using liquid chromatography coupled online with electrospray ionization tandem mass spectrometry (LC-ESI-MS/MS). Precursor ion scanning in the negative ion (NI) mode was used to identify all glyceollin metabolites based on production of a diagnostic radical product ion (m/z 148) upon decomposition. Using this approach, precursor peaks of interest were found at m/z 474 and 531. Tandem mass spectra of these two peaks allowed us to characterize them as byproducts of glutathione conjugation. The peak at m/z 474 was identified as the deprotonated cysteinyl conjugate of glyceollins with an addition of an oxygen atom, whereas m/z 531 was identified as the deprotonated cysteinylglyceine glyceollin conjugate plus an oxygen. These results were confirmed by positive ion (PI) mode analyses. Mercapturic acid conjugates of glyceollins were also identified in NI mode. In addition, glucuronidation of glyceollins was observed, giving a peak at m/z 513 corresponding to the deprotonated conjugate. Production of glucuronic acid conjugates of glyceollins was confirmed in vitro in rat liver microsomes. Neither glutathione conjugation byproducts nor glucuronic acid conjugates of glyceollins have been previously reported.

TI Bovine Exome Sequence Analysis and Targeted SNP Genotyping of Recessive
Fertility Defects BH1, HH2, and HH3 Reveal a Putative Causative Mutation
in SMC2 for HH3
SO PLOS ONE
LA English
DT Article
ID CATTLE
AB The recent discovery of bovine haplotypes with negative effects on fertility in the Brown Swiss, Holstein, and Jersey breeds has allowed producers to identify carrier animals using commercial single nucleotide polymorphism (SNP) genotyping assays. This study was devised to identify the causative mutations underlying defective bovine embryo development contained within three of these haplotypes (Brown Swiss haplotype 1 and Holstein haplotypes 2 and 3) by combining exome capture with next generation sequencing. Of the 68,476,640 sequence variations (SV) identified, only 1,311 genome-wide SNP were concordant with the haplotype status of 21 sequenced carriers. Validation genotyping of 36 candidate SNP identified only 1 variant that was concordant to Holstein haplotype 3 (HH3), while no variants located within the refined intervals for HH2 or BH1 were concordant. The variant strictly associated with HH3 is a non-synonymous SNP (T/C) within exon 24 of the Structural Maintenance of Chromosomes 2 (SMC2) on Chromosome 8 at position 95,410,507 (UMD3.1). This polymorphism changes amino acid 1135 from phenylalanine to serine and causes a non-neutral, non-tolerated, and evolutionarily unlikely substitution within the NTPase domain of the encoded protein. Because only exome capture sequencing was used, we could not rule out the possibility that the true causative mutation for HH3 might lie in a non-exonic genomic location. Given the essential role of SMC2 in DNA repair, chromosome condensation and segregation during cell division, our findings strongly support the non-synonymous SNP (T/C) in SMC2 as the likely causative mutation. The absence of concordant variations for HH2 or BH1 suggests either the underlying causative mutations lie within a non-exomic region or in exome regions not covered by the capture array.

TI Lipoprotein Metabolism Indicators Improve Cardiovascular Risk Prediction
SO PLOS ONE
LA English
DT Article
ID QUANTIFICATION; CHOLESTEROL; PLASMA
AB Background: Cardiovascular disease risk increases when lipoprotein metabolism is dysfunctional. We have developed a computational model able to derive indicators of lipoprotein production, lipolysis, and uptake processes from a single lipoprotein profile measurement. This is the first study to investigate whether lipoprotein metabolism indicators can improve cardiovascular risk prediction and therapy management.
Methods and Results: We calculated lipoprotein metabolism indicators for 1981 subjects (145 cases, 1836 controls) from the Framingham Heart Study offspring cohort in which NMR lipoprotein profiles were measured. We applied a statistical learning algorithm using a support vector machine to select conventional risk factors and lipoprotein metabolism indicators that contributed to predicting risk for general cardiovascular disease. Risk prediction was quantified by the change in the Area-Under-the-ROC-Curve (Delta AUC) and by risk reclassification (Net Reclassification Improvement (NRI) and Integrated Discrimination Improvement (IDI)). Two VLDL lipoprotein metabolism indicators (VLDLE and VLDLH) improved cardiovascular risk prediction. We added these indicators to a multivariate model with the best performing conventional risk markers. Our method significantly improved both CVD prediction and risk reclassification.
Conclusions: Two calculated VLDL metabolism indicators significantly improved cardiovascular risk prediction. These indicators may help to reduce prescription of unnecessary cholesterol-lowering medication, reducing costs and possible side-effects. For clinical application, further validation is required.

AB Changes in land use, land cover, and land management present some of the greatest potential global environmental challenges of the 21st century. Urbanization, one of the principal drivers of these transformations, is commonly thought to be generating land changes that are increasingly similar. An implication of this multiscale homogenization hypothesis is that the ecosystem structure and function and human behaviors associated with urbanization should be more similar in certain kinds of urbanized locations across biogeophysical gradients than across urbanization gradients in places with similar biogeophysical characteristics. This paper introduces an analytical framework for testing this hypothesis, and applies the framework to the case of residential lawn care. This set of land management behaviors are often assumed-not demonstrated-to exhibit homogeneity. Multivariate analyses are conducted on telephone survey responses from a geographically stratified random sample of homeowners (n = 9,480), equally distributed across six US metropolitan areas. Two behaviors are examined: lawn fertilizing and irrigating. Limited support for strong homogenization is found at two scales (i.e., multi- and single-city; 2 of 36 cases), but significant support is found for homogenization at only one scale (22 cases) or at neither scale (12 cases). These results suggest that US lawn care behaviors are more differentiated in practice than in theory. Thus, even if the biophysical outcomes of urbanization are homogenizing, managing the associated sustainability implications may require a multiscale, differentiated approach because the underlying social practices appear relatively varied. The analytical approach introduced here should also be productive for other facets of urban-ecological homogenization.

AB Satellite-based passive microwave remote sensing has been shown to be a valuable tool in mapping and monitoring global soil moisture. The Advanced Microwave Scanning Radiometer on the Aqua platform (AMSR-E) has made significant contributions to this application. As the result of agency and individual initiatives, several approaches for the retrieval of soil moisture from AMSR-E have been proposed and implemented. Although the majority of these are based on the same Radiative Transfer Equation, studies have shown that the resulting soil moisture estimates can differ significantly. A primary goal of this investigation is to understand these differences and develop a suitable approach to potentially improve the algorithm currently used by NASA in producing its operational soil moisture product In order to achieve this goal, the theoretical basis of several alternative soil moisture retrieval algorithms are examined. Analysis has focused on five established approaches: the operational algorithm adopted by NASA, which is referred to as the Normalized Polarization Difference algorithm, the Single Channel Algorithm, the Land Parameter Retrieval Model, the University of Montana soil moisture algorithm, and the HydroAlgo Artificial Neural Network algorithm. Previous comparisons of these algorithms in the literature have typically focused on the retrieved soil moisture products, and employed different metrics and data sets, and have resulted in differing conclusions. In this investigation we attempt to provide a more thorough understanding of the fundamental differences between the algorithms and how these differences affect their performance in terms of range of soil moisture provided. The comparative overview presented in the paper is based on the operating versions of the source codes of the individual algorithms. Analysis has indicated that the differences between algorithms lie in the specific parameterizations and assumptions of each algorithm. The comparative overview of the theoretical basis of the approaches is linked to differences found in the soil moisture retrievals, leading to suggestions for improvements and increased reliability in these algorithms.

TI Genome-wide association study for intramuscular fat deposition and
composition in Nellore cattle
SO BMC GENETICS
LA English
DT Article
DE Fatty acid; GWAS; Bos indicus; Beef; Positional candidate gene
AB Background: Meat from Bos taurus and Bos indicus breeds are an important source of nutrients for humans and intramuscular fat (IMF) influences its flavor, nutritional value and impacts human health. Human consumption of fat that contains high levels of monounsaturated fatty acids (MUFA) can reduce the concentration of undesirable cholesterol (LDL) in circulating blood. Different feeding practices and genetic variation within and between breeds influences the amount of IMF and fatty acid (FA) composition in meat. However, it is difficult and costly to determine fatty acid composition, which has precluded beef cattle breeding programs from selecting for a healthier fatty acid profile. In this study, we employed a high-density single nucleotide polymorphism (SNP) chip to genotype 386 Nellore steers, a Bos indicus breed and, a Bayesian approach to identify genomic regions and putative candidate genes that could be involved with deposition and composition of IMF.
Results: Twenty-three genomic regions (1-Mb SNP windows) associated with IMF deposition and FA composition that each explain >= 1% of the genetic variance were identified on chromosomes 2, 3, 6, 7, 8, 9, 10, 11, 12, 17, 26 and 27. Many of these regions were not previously detected in other breeds. The genes present in these regions were identified and some can help explain the genetic basis of deposition and composition of fat in cattle.
Conclusions: The genomic regions and genes identified contribute to a better understanding of the genetic control of fatty acid deposition and can lead to DNA-based selection strategies to improve meat quality for human consumption.

AB Background: Recently, RNA sequencing (RNA-seq) has rapidly emerged as a major transcriptome profiling system. Elucidation of the bovine mammary gland transcriptome by RNA-seq is essential for identifying candidate genes that contribute to milk composition traits in dairy cattle.
Results: We used massive, parallel, high-throughput, RNA-seq to generate the bovine transcriptome from the mammary glands of four lactating Holstein cows with extremely high and low phenotypic values of milk protein and fat percentage. In total, we obtained 48,967,376-75,572,578 uniquely mapped reads that covered 82.25% of the current annotated transcripts, which represented 15549 mRNA transcripts, across all the four mammary gland samples. Among them, 31 differentially expressed genes (p < 0.05, false discovery rate q < 0.05) between the high and low groups of cows were revealed. Gene ontology and pathway analysis demonstrated that the 31 differently expressed genes were enriched in specific biological processes with regard to protein metabolism, fat metabolism, and mammary gland development (p < 0.05). Integrated analysis of differential gene expression, previously reported quantitative trait loci, and genome-wide association studies indicated that TRIB3, SAA (SAA1, SAA3, and M-SAA3.2), VEGFA, PTHLH, and RPL23A were the most promising candidate genes affecting milk protein and fat percentage.
Conclusions: This study investigated the complexity of the mammary gland transcriptome in dairy cattle using RNA-seq. Integrated analysis of differential gene expression and the reported quantitative trait loci and genome-wide association study data permitted the identification of candidate key genes for milk composition traits.

TI Sound management may sequester methane in grazed rangeland ecosystems
SO SCIENTIFIC REPORTS
LA English
DT Article
ID EMISSIONS; CHINA; SHEEP
AB Considering their contribution to global warming, the sources and sinks of methane (CH4) should be accounted when undertaking a greenhouse gas inventory for grazed rangeland ecosystems. The aim of this study was to evaluate the mitigation potential of current ecological management programs implemented in the main rangeland regions of China. The influences of rangeland improvement, utilization and livestock production on CH4 flux/emission were assessed to estimate CH4 reduction potential. Results indicate that the grazed rangeland ecosystem is currently a net source of atmospheric CH4. However, there is potential to convert the ecosystem to a net sink by improving management practices. Previous assessments of capacity for CH4 uptake in grazed rangeland ecosystems have not considered improved livestock management practices and thus underestimated potential for CH4 uptake. Optimal fertilization, rest and light grazing, and intensification of livestock management contribute mitigation potential significantly.

AB A fundamental understanding of the morphological development of cellulose fibers during fibrillation using micro grinder is very essential to develop effective strategies for process improvement and to reduce energy consumption. We demonstrated some simple measures for characterizing cellulose fibers fibrillated at different fibrillation times through the grinder. The morphology and degree of fibrillation of the samples at different stages of fibrillation were characterized. The fibrillation and mechanical properties reached a maximum in 2 h, and did not show any significant change with further grinding. The lateral dimensions of the smallest nanofibrils were between 15 and 40 nm. A slight reduction in the crystallinity and degree of polymerization did not lead to decrease in mechanical properties of cellulose films. The lower tensile properties at the initial stages of fibrillation are mainly due to the presence of limited refined and heterogeneously treated fibers.

AB Recent declines in bee populations coupled with advances in DNA-sequencing technology have sparked a renaissance in studies of bee-associated microbes. Megachile rotundata is an important field crop pollinator, but is stricken by chalkbrood, a disease caused by the fungus Ascosphaera aggregata. To test the hypothesis that some gut microbes directly or indirectly affect the growth of others, we applied four treatments to the pollen provisions of M. rotundata eggs and young larvae: antibacterials, antifungals, A. aggregata spores and a no-treatment control. We allowed the larvae to develop, and then used 454 pyrosequencing and quantitative PCR (for A. aggregata) to investigate fungal and bacterial communities in the larval gut. Antifungals lowered A. aggregata abundance but increased the diversity of surviving fungi. This suggests that A. aggregata inhibits the growth of other fungi in the gut through chemical or competitive interaction. Bacterial richness decreased under the antifungal treatment, suggesting that changes in the fungal community caused changes in the bacterial community. We found no evidence that bacteria affect fungal communities. Lactobacillus kunkeei clade bacteria were common members of the larval gut microbiota and exhibited antibiotic resistance. Further research is needed to determine the effect of gut microbes on M. rotundata health.

AB Background: Herbicide resistance in weedy plant populations can develop through different mechanisms such as gene flow of herbicide resistance transgenes from crop species into compatible weedy species or by natural evolution of herbicide resistance or tolerance following selection pressure. Results from our previous studies suggest that sub-lethal levels of the herbicide glyphosate can alter the pattern of gene flow between glyphosate resistant Canola (R), Brassica napus, and glyphosate sensitive varieties of B. napus and B. rapa. The objectives of this study were to examine the phenological and developmental changes that occur in Brassica crop and weed species following sub-lethal doses of the herbicides glyphosate and glufosinate. We examined several vegetative and reproductive traits of potted plants under greenhouse conditions, treated with sub-lethal herbicide sprays.
Results: Our results indicate that exposure of Brassica spp. to a sub-lethal dose of glyphosate results in altering flowering phenology and reproductive function. Flowering of all sensitive species was significantly delayed and reproductive function, specifically male fertility, was suppressed. Higher dosage levels typically contributed to an increase in the magnitude of phenotypic changes.
Conclusions: These results demonstrate that Brassica spp. plants that are exposed to sub-lethal doses of glyphosate could be subject to very different pollination patterns and an altered pattern of gene flow that would result from changes in the overlap of flowering phenology between species. Implications include the potential for increased glyphosate resistance evolution and spread in weedy communities exposed to sub-lethal glyphosate.

AB The effects of insect infestation in agricultural crops are of major ecological and economic interest because of reduced yield, increased cost of pest control and increased risk of environmental contamination from insecticide application. The Russian wheat aphid (RWA, Diuraphis noxia) is an insect pest that causes damage to wheat (Triticum aestivum L.). We proposed that concentrated RWA feeding areas, referred to as "hotspots," could be identified and isolated from uninfested areas within a field for site specific aphid management using remotely sensed data. Our objectives were to ( 1) investigate the reflectance characteristics of infested and uninfested wheat by RWA and (2) evaluate utility of airborne hyperspectral imagery with 1-m spatial resolution for detecting, quantifying, and mapping RWA infested areas in commercial winter wheat fields using the constrained energy minimization classifier. Percent surface reflectance from uninfested wheat was lower in the visible and higher in the near infrared portions of the spectrum when compared with RWA-infested wheat. The overall classification accuracies of > 89% for damage detection were achieved. These results indicate that hyperspectral imagery can be effectively used for accurate detection and quantification of RWA infestation in wheat for site-specific aphid management. (C) The Authors.

AB We document significant worldwide weather anomalies that affected agriculture and vector-borne disease outbreaks during the 2010-2012 period. We utilized 2000-2012 vegetation index and land surface temperature data from NASA's satellite-based Moderate Resolution Imaging Spectroradiometer (MODIS) to map the magnitude and extent of these anomalies for diverse regions including the continental United States, Russia, East Africa, Southern Africa, and Australia. We demonstrate that shifts in temperature and/or precipitation have significant impacts on vegetation patterns with attendant consequences for agriculture and public health. Weather extremes resulted in excessive rainfall and flooding as well as severe drought, which caused similar to 10 to 80% variation in major agricultural commodity production (including wheat, corn, cotton, sorghum) and created exceptional conditions for extensive mosquito-borne disease outbreaks of dengue, Rift Valley fever, Murray Valley encephalitis, and West Nile virus disease. Analysis of MODIS data provided a standardized method for quantifying the extreme weather anomalies observed during this period. Assessments of land surface conditions from satellite-based systems such as MODIS can be a valuable tool in national, regional, and global weather impact determinations.

AB Eustoma grandiflorum (Raf.) Shinn. (lisianthus) is a moderately salt tolerant species that can be produced commercially under irrigation with saline wastewaters prevalent in two salt-affected areas of California. The objective of the present studies was to determine the effect of irrigation with saline waters of two different compositions on the ion accumulation and ion relations of lisianthus Pure White' and Echo Blue'. The ionic composition of irrigation waters simulated the compositions typical of i) seawater dilutions (SWD) and ii) concentrations of Colorado River water (CCRW). Electrical conductivities (EC) of SWD and CCRW were between 2 and 12 dS m(-1). Plants irrigated with CCRW were higher in Ca2+ compared to plants irrigated with SWD water. Calcium was also higher in Pure White' than in Echo Blue'. Increasing EC of irrigation water caused a significant decrease in shoot and leaf Ca2+ concentration in Echo Blue', but had no effect on Ca2+ content of Pure White' shoots and leaves. Magnesium concentration in Echo Blue' was higher than in Pure White'. Electrical conductivity did not significantly affect Mg2+ concentration of either cultivar, despite the increasingly higher external concentration. Potassium concentration of young and mature leaves of Echo Blue' increased as EC increased from 2 to 8 dS m(-1), then decreased significantly once EC exceeded 8 dS m(-1). Potassium concentration of Pure White' leaves decreased over the range of salinity treatments tested, suggesting that the reduced potassium ion (K+) activity at EC levels of 8 dS m(-1), or less, that resulted in lower leaf-K+ in Pure White' did not cause a decrease in K+ uptake in Echo Blue'. Increases in external Na+ caused a significant increase in Na+ in Pure White' leaves and these plants exhibited the best growth even when levels of Na+ were high enough to be considered detrimental for growth.

AB The aim of this study was to determine the salt tolerance of pepper (Capsicum annuum L.) under greenhouse conditions and to examine the interactive effects of salinity and nitrogen (N) fertilizer levels on yield. The present study shows the effects of optimal and suboptimal N fertilizer levels (270kg ha(-1) and 135kg ha(-1)) in combination with five different irrigation waters of varying electrical conductivity (EC) (ECiw = 0.25, 1.0, 1.5, 2.0, 4.0, and 6.0 dS m(-1)) and three replicates per treatment. At optimal N level, yield decreased when the irrigation water salinity was above ECiw 2 dS m(-1). At the suboptimal N level, a significant decrease in yield occurred only above ECiw 4 dS m(-1). At high salinity levels the salinity stress was dominant with respect to yield and response was similar for both N levels. Based on the results it can also be concluded that under saline conditions (higher than threshold salinity for a given crop) there is a lesser need for N fertilization relative to the optimal levels established in the absence of other significant stresses.

DE Solid fats; Added sugars; WWEIA; NHANES; Diet quality
AB Background: The 2010 Dietary Guidelines for Americans (DGA) recommend that individuals age two years and older reduce intakes of solid fats (SoF) and added sugars (AS; together SoFAS). MyPlate illustrates the proportions of five major food groups to promote healthy eating (Vegetables, Grains, Protein Foods, Fruits and Dairy).
Methods: To assess if the foods currently consumed by Americans are in concordance with the DGA, food consumption data from What We Eat In America, National Health and Nutrition Examination Survey (WWEIA- NHANES) 2007- 2008 (n = 8 527) was used to estimate the proportion of foods that contained SoFAS and to report them by food group. Weighted analysis was conducted to be nationally representative.
Results: The Dairy group contained the highest proportion (93%) of either SoF or AS, followed by Grains (70% SoF; 70% AS; 50% both). Fruits contained the least SoFAS (7%).
Conclusions: Results suggest that the high proportion of SoFAS in each recommended food group makes it challenging for Americans to reduce their intake of SoFAS.

AB Two enrichment methods for Listeria monocytogenes using Immuno Magnetic Separation (IMS) were tested to determine if they selected the same subtypes of isolates. Both methods used a non-selective primary enrichment and one included subculture in Fraser Broth, while the other involved direct plating of IMS beads. Sixty-two naturally contaminated watershed samples from the Central California Coast were used as a source of L. monocytogenes, and subtype diversity was measured by serotype and Multiple Number Variable Tandem Repeat Analysis (MLVA). Three different serotypes were detected from both methods with serotype 4b strains making up 87% of the isolates, serotype 1/2a making up 8%, and serotype 1/2b making up 5%. The data suggest that serotype 1/2a strains were more likely to be isolated from the Fraser Broth culture method. Sixty-two different MLVA types were detected and the more common MLVA types were detected by both culture methods. Forty-three MLVA types were detected only from one culture method or the other, while 19 types were detected from both culture methods. The most common MLVA type-12 was detected in 33 of the 62 water samples, and represented 31% of the isolates from both culture methods. This limited study provides evidence that using both enrichment culture methods allowed for detection of a greater diversity of isolates among the samples than the use of one method alone, and that a wide diversity of L. monocytogenes strains exist in this watershed.

AB The present study investigated the antibacterial effect of a bioprocessed polysaccharide (BPP) isolated from Lentinus edodes liquid mycelial culture supplemented with black rice bran against murine salmonellosis. BPP was not bactericidal in vitro, it did, however, stimulate uptake of the bacteria into RAW 264.7 murine macrophage cells, as indicated by increased colony-forming unit (CFU) counts of the contents of the lysed macrophages incubated with Salmonella Typhimurium for 30 and 60 mm. Two hours postinfection, the bacterial counts drastically increased in the macrophages, but 4 and 8 h postinfection BPP extract-treated cells showed lower bacterial counts than the vehicle (saline phosphate pH 7.4 buffer, PBS)-treated control. BPP elicited altered morphology and markedly elevated inducible nitric oxide (NO) synthase (iNOS) mRNA and protein expression in the infected macrophage cells. BPP also activated leukocytes in S. Typhimurium-infected mice, as determined by spleen lymphocyte proliferation and IFN-gamma levels in mice sera. ELISA analysis on cytokine production by Th1 and Th2 immune cells from splenocytes of infected mice showed significant increases in the levels of the following Th1 cytokines: IL-1 beta, IL-2, IL-6, and IL-12. Histology assays of the livers of mice infected with a sublethal dose (1 x 10(4) CFU) of S. Typhimurium showed that BPP, administered daily through an intraperitoneal (ip) or oral route, protected against necrosis of the liver, a biomarker of in vivo salmonellosis. The lifespan of mice similarly infected with a lethal dose of S. Typhimurium (1 x 10(5) CFU) was significantly extended by ip injection or oral administration of the BPP without side effects. These results suggest that the activity of BPP against bacterial infection in mice occurs mainly through the activation of macrophage-mediated immune response resulting from augmented Th1 immunity. The significance of the results for microbial food safety and human health and further research needs are discussed.

AB Maruca vitrata Fabricius (Lepidoptera: Crambidae) is a polyphagous insect pest that feeds on a variety of leguminous plants in the tropics and subtropics. The contribution of host-associated genetic variation on population structure was investigated using analysis of mitochondrial cytochrome oxidase 1 (cox1) sequence and microsatellite marker data from M. vitrata collected from cultivated cowpea (Vigna unguiculata L. Walp.), and alternative host plants Pueraria phaseoloides (Roxb.) Benth. var. javanica (Benth.) Baker, Loncocarpus sericeus (Poir), and Tephrosia candida (Roxb.). Analyses of microsatellite data revealed a significant global FST estimate of 0.05 (P <= 0.001). The program STRUCTURE estimated 2 genotypic clusters (co-ancestries) on the four host plants across 3 geographic locations, but little geographic variation was predicted among genotypes from different geographic locations using analysis of molecular variance (AMOVA; among group variation -0.68%) or F-statistics (F-ST(Loc) = 20.01; P = 0.62). These results were corroborated by mitochondrial haplotype data (phi(Loc)(ST) = 0.05; P = 0.92). In contrast, genotypes obtained from different host plants showed low but significant levels of genetic variation (F-ST(Host) = 0.04; P = 0.01), which accounted for 4.08% of the total genetic variation, but was not congruent with mitochondrial haplotype analyses (phi(Host)(ST) = 0.06; P = 0.27). Variation among host plants at a location and host plants among locations showed no consistent evidence for M. vitrata population subdivision. These results suggest that host plants do not significantly influence the genetic structure of M. vitrata, and this has implications for biocontrol agent releases as well as insecticide resistance management (IRM) for M. vitrata in West Africa.

AB A recombinant inbred line (RIL) mapping population developed from a cross between winter wheat (Triticum aestivum L.) cultivars Coda and Brundage was evaluated for reaction to stripe rust (caused by Puccinia striiformis f. sp. tritici). Two hundred and sixty eight RIL from the population were evaluated in replicated field trials in a total of nine site-year locations in the U. S. Pacific Northwest. Seedling reaction to stripe rust races PST-100, PST-114 and PST-127 was also examined. A linkage map consisting of 2,391 polymorphic DNA markers was developed covering all chromosomes of wheat with the exception of 1D. Two QTL on chromosome 1B were associated with adult plant and seedling reaction and were the most significant QTL detected. Together these QTL reduced adult plant infection type from a score of seven to a score of two reduced disease severity by an average of 25% and provided protection against race PST-100, PST-114 and PST-127 in the seedling stage. The location of these QTL and the race specificity provided by them suggest that observed effects at this locus are due to a complementation of the previously known but defeated resistances of the cultivar Tres combining with that of Madsen (the two parent cultivars of Coda). Two additional QTL on chromosome 3B and one on 5B were associated with adult plant reaction only, and a single QTL on chromosome 5D was associated with seedling reaction to PST-114. Coda has been resistant to stripe rust since its release in 2000, indicating that combining multiple resistance genes for stripe rust provides durable resistance, especially when all-stage resistance genes are combined in a fashion to maximize the number of races they protect against. Identified molecular markers will allow for an efficient transfer of these genes into other cultivars, thereby continuing to provide excellent resistance to stripe rust.

AB Background: Grasspea (Lathyrus sativus L., 2n = 14), a member of the family Leguminosae, holds great agronomic potential as grain and forage legume crop in the arid areas for its superb resilience to abiotic stresses such as drought, flood and salinity. The crop could not make much progress through conventional breeding in the past, and there are hardly any detailed molecular biology studies due to paucity of reliable molecular markers representative of the entire genome.
Results: Using the 454 FLX Titanium pyrosequencing technique, 651,827 simple sequence repeat (SSR) loci were identified and 50,144 nonredundant primer pairs were successfully designed, of which 288 were randomly selected for validation among 23 L. sativus and one L. cicera accessions of diverse provenance. 74 were polymorphic, 70 monomorphic, and 144 with no PCR product. The number of observed alleles ranged from two to five, the observed heterozygosity from 0 to 0.9545, and Shannon's information index ranged from 0.1013 to 1.0980, respectively. The dendrogram constructed by using unweighted pair group method with arithmetic mean (UPGMA) based on Nei's genetic distance, showed obvious distinctions and understandable relationships among the 24 accessions.
Conclusions: The large number of SSR primer pairs developed in this study would make a significant contribution to genomics enabled improvement of grasspea.

AB Neospora caninum is a common cause of abortion in cattle worldwide. Canids, including the dog and the dingo (Canis familiaris), the coyote (Canis latrans), and the gray wolf (Canis lupus) are its definitive hosts that can excrete environmentally resistant oocysts in the environment, but also can act as intermediate hosts, harboring tissue stages of the parasite. In an attempt to isolate viable N. caninum from tissues of naturally infected wolves, brain and heart tissue from 109 wolves from Minnesota were bioassayed in mice. Viable N. caninum (NcWolfMn1, NcWolfMn2) was isolated from the brains of two wolves by bioassays in interferon gamma gene knockout mice. DNA obtained from culture-derived N. caninum tachyzoites of the two isolates were analyzed by N. caninum-specific Nc5 polymerase chain reaction and confirmed diagnosis. This is the first report of isolation of N. caninum from tissues of any wild canid host. Published by Elsevier B.V.

AB Crops frequently contaminated by aflatoxins are important sources of revenue and daily nourishment in many portions of sub-Saharan Africa. In recent years, reports have associated aflatoxins with diminished human health and export opportunities in many African Nations. Aflatoxins are highly carcinogenic metabolites mainly produced by members of Aspergillus sect. Flavi. The current study examined aflatoxin-producing fungi associated with maize grain intended for human consumption in 18 sub-Saharan African countries. 4469 Aspergillus sect. Flavi isolates were obtained from 339 samples. The majority (75%) of isolates belonged to the L strain morphotype of A. flavus. Minor percentages were A. tamarii (6%), A. parasiticus (1%), and isolates with S strain morphology (3%). No A. bombycis or A. nomius isolates were detected. Phylogenetic analyses of partial sequences of the nitrate reductase gene (niaD, 1.3 kb) and the aflatoxin pathway transcription factor gene (aflR, 1.7 kb) were used to verify isolate assignments into species and lineages. Phylogenetics resolved S strain isolates producing only B aflatoxins into two lineages fully supported by sizes of deletions in the gene region spanning the aflatoxin biosynthesis genes cypA (aflU) and norB (aflF). One lineage was the A. flavus S strain with either 0.9 or 1.5 kb deletions. The second lineage, recently described from Kenya, has a 2.2 kb deletion. Taxa with S strain morphology differed in distribution with strain S-BG limited to West Africa and both A. minisclerotigenes and the new lineage from Kenya in Central and East Africa. African A. flavus L strain isolates formed a single clade with L strain isolates from other continents. The sampled maize frequently tested positive for aflatoxins (65%), fumonisins (81%), and deoxynivalenol (40%) indicating the presence of fungi capable of producing the respective toxins. Percentage of samples exceeding US limits for total aflatoxins (regulatory limit), fumonisins (advisory limit), and deoxynivalenol (advisory limit) were 47%, 49%, 4%, respectively.

AB Adaptation of agricultural industries to climate change will make a major difference to the extent of the impacts experienced as a result of climate change. Vulnerability assessments provide the basis for developing strategies to reduce social vulnerability and plan for climate adaptation. Primary industries have been identified as the most vulnerable industry sector globally. We review how primary producers might be socially vulnerable to climate change and develop a 'vulnerability typology' of cattle producers based on survey responses from 240 producers across northern Australia. We measured social vulnerability according to ten indicators of climate sensitivity (resource dependency) and four indicators of adaptive capacity. Using a K-means clustering analysis we identified four main types' of cattle producers. Type 1 producers (43%) were vulnerable because they had low strategic skills and low interest in changing behaviour. Mean age was 59 years old, they were weakly networked within the industry and businesses were small. Type II producers (41%) had low strategic skills, poorly managed risk and uncertainty, had medium sized businesses and were 51 years old on average. Only 16% of producers (Type III and IV) appeared to have resilience to change. Type III producers (13.4%) had a stronger psychological and financial buffer, were 52 years old on average, were well networked and managed or owned larger businesses. Type IV producers (2.6%) managed risk well, liked to experiment with options and were interested in change. They were 41 years old on average, managed extremely large properties, were well networked, perceived themselves as responsible for the future productivity of their land and were early adopters of new technology. By providing knowledge of the different ways in which people can be vulnerable to climate change, vulnerability assessments can enable decision-makers to prioritise their efforts, provide a basis for early engagement, and tailor a range of adaptation approaches to most effectively accommodate and support the divergent requirements of different "types" of resource-users.

AB Subsurface nutrient losses differ between annual and perennial crops; however, nutrient losses from cropping systems that rotate annual and perennial crops are poorly documented. This study tracked NO3-N and P in soil water under three cropping systems suited for the U.S. Midwest, including two-year (corn-soybean; 2YS), three-year (corn-soybean-small grain/red clover; 3YS), and four-year (corn-soybean-small grain/alfalfa-alfalfa; 4YS) systems. Nutrient applications were based on soil-test results, and solely comprised inorganic fertilizers to 2YS corn, whereas, in the 3YS and 4YS systems, nutrients were provided by legume residues, and a managed balance of composted manure, and inorganic fertilizers. Soil water was collected from 2004 through 2011 using suction samplers. The 4YS system had smaller concentrations of NO3-N and a lower frequency of P detection (p < 0.05) during the established alfalfa and subsequent corn crop than other crop-years in the experiment. Mean concentrations of NO3-N were 1.1 mg NO3-NL-1 under alfalfa and 6.5 mg NO3-NL-1 under the following 4YS corn crop, compared to average concentrations between 8.7 and 18.1 mg NO3-NL-1 among all other crop-years. Seasonal NO3N dynamics among the three systems were explainable based on mineralization and - immobilization of N from decomposing crop residues. Large P concentrations (0.23-1.02 mg PL-1) occurred in one plot that occasionally ponded, indicating P transport to depth by preferential flow is a risk in some soils on this landscape. Among the remaining plots, the proportion of samples with detectable P concentrations (i.e., >0.02 mg L-1) was less (p < 0.05) under the 4YS system (0.26) than observed for the experiment overall (0.35), which resulted from infrequent detection (0.17) of P in soil water during the alfalfa and corn crops. Results provide evidence that rotational systems including alfalfa with annual crops and use of soil testing in nutrient management can reduce movement of N and P below the root zone.

AB Landscape simplification associated with agricultural intensification has important effects on economically important arthropods. The declining cover of natural and semi-natural habitats, in particular, has been shown to reduce natural-enemy attack of crop pests, but also in some cases reduced crop colonization by such pests. In this study, we examined the influence of changes in two elements of landscape composition, natural grassland cover and cover of a highly suitable crop host, on infestation by a generalist insect pest in wheat, and parasitism of this pest by its dominant natural enemies. Surprisingly, we found no significant influences of increasing natural grassland habitat, at either local or landscape scales, on infestation by the wheat stem sawfly, Cephus cinctus, or parasitism of this pest by the native parasitoid wasps, Bracon cephi and Bracon lissogaster. In contrast, we found significant increases in levels of C cinctus infestation with increasing wheat cover at the landscape scale. This pattern was consistent across six study regions spanning three states in the northern Great Plains of North America, despite large differences in cropping systems and pest population densities across regions. Regional variation in pest infestation was best explained by long-term averages in precipitation, with higher C. cinctus infestation rates found in drier regions. Results suggest that landscape-mediated variation in pest pressure in this system is better explained by a direct response of pest insects to increasing cover of a highly suitable crop rather than an indirect response via reductions in natural enemies as natural habitat declines. The implication is that habitat diversification at the landscape scale could play a role in suppressing agricultural pest populations via reductions in area of suitable crop hosts.

AB Lactobacillus brevis ATCC 8287, a surface (S-layer) strain, possesses a variety of functional properties that make it both a potential probiotic and a good vaccine vector candidate. With this in mind, our aim was to study the survival of L brevis in the porcine gut and investigate the effect of this strain on the growth and immune function of recently weaned piglets during a feeding trial. For this, 20 piglets were divided evenly into a treatment and a control group. Piglets in the treatment group were fed L brevis cells (1 x 10(10)) daily for three weeks, whereas those in the control group were provided an equivalent amount of probiotic-free placebo. For assessing the impact of L brevis supplementation during the feeding trial, health status and weight gain of the piglets were monitored, pre- and post-trial samples of serum and feces were obtained, and specimens of the small and large intestinal mucosa and digesta were collected at slaughter. The results we obtained indicated that L. brevis-supplemented feeding induced a non-significant increase in piglet body weight and caused no change in the morphology of the intestinal mucosa. L. brevis cells were found to localize mainly in the large intestine, but they could not be isolated from feces. To a lesser extent, L. brevis was detected in the small intestine, although there was no specific attachment to the Peyer's patches. Changes in total serum IgG and IgA concentrations were not caused by supplemented L brevis and no measurable rise in L brevis-specific IgG was observed. However, analysis of cytokine gene expression in intestinal mucosa revealed, downregulation of TGF-beta 1 in the ileum and upregulation of IL-6 in the cecum in the L. brevis-supplemented group. Based on the results from this study, we conclude that whereas brevis appears to have some intestinal immunomodulatoly effects, the ability of this strain to survive and colonize within the porcine gut appears to be limited.

AB Pikes Peak Highway is a partially paved road between Cascade, Colorado and the summit of Pikes Peak. Significant gully erosion is occurring on the hillslopes due to the concentration of surface runoff, the rearrangement of drainage pathways along the road surface and adjacent drainage ditches, and the high erodibility of weathered Pikes Peak granite that underlies the area. As a result, large quantities of sediment are transported to surrounding valley networks causing significant damage to water quality and aquatic, wetland, and riparian ecosystems. This study establishes the slope/drainage area threshold for gullying along Pikes Peak Highway and a cesium-137 based sediment budget highlighting rates of gully erosion and subsequent valley deposition for a small headwater basin. The threshold for gullying along the road is S-cr=021A(-045) and the road surface reduces the critical slope requirement for gullying compared to natural drainages in the area. Total gully volume for the 20 gullies along the road is estimated at 5974 m(3), with an erosion rate of 64 m(3) yr(-1) to 101 m(3) yr(-1). Net valley deposition is estimated at 162 m(3) yr(-1) with 120 m(3) yr(-1) unaccounted for by gullying. The hillslope-channel interface is decoupled with minimal downstream sediment transport which results in significant local gully-derived sedimentation. Copyright (c) 2013 John Wiley & Sons, Ltd.

AB Optical remote sensing of crop nitrogen (N) status is developing into a powerful diagnostic tool that can improve N management decisions. Crop N status is a function of dry mass per unit area (Win t ha(-1)) and N concentration (%N-a), which can be used to calculate N nutrition index (NNI), where NNI is %N-a/N-c (%N-a is actual N concentration and %N-c is the minimum N concentration required for maximum growth). Using optical remote sensing to estimate crop N status is particularly important during the critical early crop developmental stages when reliable data could still guide effective in-season N fertilizer management decisions (e.g., by adding topdressed fertilizer). However, because the spectral signal measured by traditional optical remote sensing devices during early crop development is often dominated by soil spectral reflectance, early season estimates of Wand %N-a are prone to large errors. Terrestrial LiDAR (light detection and ranging) scanning (TLS) may alleviate errors as fine scale TLS point data can be used to directly quantify physical W proxies (e.g., crop height or volume) and derive %N-a from green (532 nm) TLS point return intensity. We evaluated the potential of TLS to assess W, %N-a and NNI of winter wheat (Triticum aestivum L). Green TLS measurements were obtained for two seasons during tillering and jointing. Strong (r(2) > = 0.72, RMSE <= 0.68 t ha(-1)) relationships occurred between observed Wand TLS-derived vegetation volume across all growth stages and seasons. A wider range of relationships existed between %N-a and green laser return intensity (r(2) = 0.10-0.75, RMSE = 0.31-0.63%). When fused to calculate a TLS based NNI, a moderately strong relationship occurred (r(2) = 0.45-0.54, RMSE = 0.11 NNI). Our results demonstrate that green TLS can provide useful information for improving N management during early season wheat growth. (C) 2014 Elsevier B.V. All rights reserved.

AB The enzymatic and biochemical properties of the proteins encoded by five potato cytokinin oxidase/dehydrogenase (CKX)-like genes functionally expressed in yeast and the effects of tuber dormancy progression on StCKX expression and cytokinin metabolism were examined in lateral buds isolated from field-grown tubers. All five putative StCKX genes encoded proteins with in vitro CKX activity. All five enzymes were maximally active at neutral to slightly alkaline pH with 2,6-dichloro-indophenol as the electron acceptor. In silico analyses indicated that four proteins were likely secreted. Substrate dependence of two of the most active enzymes varied; one exhibiting greater activity with isopentenyl-type cytokinins while the other was maximally active with cis-zeatin as a substrate. [H-3]-isopentenyl-adenosine was readily metabolized by excised tuber buds to adenine/adenosine demonstrating that CKX was active in planta. There was no change in apparent in planta CKX activity during either natural or chemically forced dormancy progression. Similarly although expression of individual StCKX genes varied modestly during tuber dormancy, there was no clear correlation between StCKX gene expression and tuber dormancy status. Thus although CKX gene expression and enzyme activity are present in potato tuber buds throughout dormancy, they do not appear to play a significant role in the regulation of cytokinin content during tuber dormancy progression.

AB The advent of the Northwest Forest Plan (NWFP) in the early 1990s signaled a new paradigm for management of 9.9 million ha of federal forest lands in western Washington and Oregon, USA. The emphasis shifted from commodity timber production to ensuring sustained ecological functioning to meet a broad array of ecosystem services including economic benefits. Under interim guidelines of the NWFP, approximately 1.1 million ha are allocated to riparian reserves intended to conserve the ecological functions and processes required to create and maintain habitat for aquatic and riparian-dependent organisms. The Density Management and Riparian Buffer Study (DMS), an operational-scale management experiment, has evaluated the effectiveness of alternative buffer widths in meeting ecological objectives for riparian areas in headwater forests subjected to spatially heterogeneous thinning. Observations in unthinned stream-reaches revealed spatial structuring of amphibian and invertebrate species assemblages in relation to headwater habitats. Riparian buffers defined by the transition between distinct riparian habitat features and upslope forest were sufficient to moderate the effect of thinning on near-stream microclimates and wetted streambed temperatures. These same variable-width buffers were less effective when adjacent to 0.4-ha patch openings. Thinning had little impact on the abundance of aquatic amphibians and there was no evidence of species loss. Results of the study are being used to devise headwater forest management and species conservation strategies, and to improve monitoring methods and watershed assessment tools.

AB This study describes the design, synthesis, and use of selective peptide substrates for cysteine peptidases of the Cl papain family, important in many biological processes. The structure of the newly synthesized substrates is Glp-Xaa-Ala-Y (where Glp = pyroglutamyl; Xaa = Phe or Val; and Y = pNA [p-nitroanilide], AMC [4-amino-7-methylcoumaride], or AFC [4-amino-7-trifluoromethyl-coumaridel]). Substrates were synthesized enzymatically to guarantee selectivity of the reaction and optical purity of the target compounds, simplifying the scheme of synthesis and isolation of products. The hydrolysis of the synthesized substrates was evaluated by C1 cysteine peptidases from different organisms and with different functions, including plant enzymes papain, bromelain, ficin, and mammalian lysosomal cathepsins B and L. The new substrates were selective for C1 cysteine peptidases and were not hydrolyzed by serine, aspartic, or metallo peptidases. We demonstrated an application of the selectivity of the synthesized substrates during the chromatographic separation of a multicomponent set of digestive peptidases from a beetle, Tenebrio molitor. Used in combination with the cysteine peptidase inhibitor E-64, these substrates were able to differentiate cysteine peptidases from peptidases of other classes in midgut extracts from T. molitor larvae and larvae of the genus Tribolium; thus, they are useful in the analysis of complex mixtures containing peptidases from different classes.

The degree of substitution (DS), the Fourier-transformed infrared spectroscopy (FTIR), the X-ray diffractograms, the thermal, morphological, and pasting properties, and the swelling power and solubility of native and acetylated starches were evaluated. The DS of the low-amylose rice starch was higher than the DS of the medium- and the high-amylose rice starches. The introduction of acetyl groups was confirmed by FTIR spectroscopy. The acetylation treatment reduced the crystallinity, the viscosity, the swelling power, and the solubility of rice starch; however, there was an increase in the thermal stability of rice starch modified by acetylation.

AB Numerous plant species worldwide including some Palicourea (Rubiaceae), Tanaecium (Bignoniaceae), and Amorimia (Malpighiaceae) species in Brazil cause sudden death and are known to contain monofluoroacetate (MFA). Two species of Palicourea, Palicourea aenofusca and Palicourea marcgravii, cause sudden death and are reported to contain MFA while other Palicourea species are reported to cause sudden death in livestock and are suspected to contain MFA due to the similarity in clinical signs. Using an HPLC-APCI-MS method to detect MFA, herbarium specimens representing 46 Palicourea taxa were screened for the presence of MFA. Additionally we screened five Psychotria taxa that are closely related to Palicourea species. Ten species of Palicourea were identified that contained MFA, two previously reported and eight newly reported here; these are closely related to each other, though some other related species did not contain MFA.

AB The importance of streambank erosion to watershed-scale sediment export is being increasingly recognized. However few studies have quantified bank erosion and watershed sediment flux at the basin scale across temporal and spatial scales. In this study we evaluated the spatial distribution, extent, and temporal frequency of bank erosion in the 5218 ha Walnut Creek watershed in Iowa across a seven year period. We inventoried severely eroding streambanks along over 10 km of stream and monitored erosion pins at 20 sites within the watershed. Annual streambank recession rates ranged from 0.6 cm/yr during years of hydrological inactivity to 28.2 cm/yr during seasons with high discharge rates, with an overall average of 18.8 cm/yr. The percentage of total basin export attributed to streambank erosion along the main stem of Walnut Creek ranged from 23 to 53%. Large variations in individual site, annual rates and percentage of annual load suggested that developing direct relationships between streambank erosion rates and total sediment discharge may be confounded by the timing and magnitude of discharge events, storage of sediments within channel system and the remobilization of eroded material.

AB Promoting effective immunity to Mycobacterium bovis infection is a challenge that is of interest to the fields of human and animal medicine alike. We report that gamma delta T cells from virulent M. bovis-infected cattle respond specifically and directly to complex, protein, and nonprotein mycobacterial Ags. Importantly, to our knowledge, we demonstrate for the first time that bovine gamma delta T cells specifically recognize peptide Ags derived from the mycobacterial protein complex ESAT6:CFP10 and that this recognition requires direct contact with APCs and signaling through the T cell Ag receptor but is independent of MHC class I or II. Furthermore, we show that M. bovis infection in cattle induces robust IL-17A protein responses. Interestingly, in contrast to results from mice, bovine CD4 T cells, and not gamma delta T cells, are the predominant source of this critical proinflammatory mediator. Bovine gamma delta T cells are divided into subsets based upon their expression of Workshop Cluster 1 (WC1), and we demonstrate that the M. bovis-specific gamma delta T cell response is composed of a heterogeneous mix of WC1-expressing populations, with the serologically defined WC1.1(+) and WC1.2(+) subsets responding in vitro to mycobacterial Ags and accumulating in the lesions of M. bovis-infected animals. The results described in this article enhance our understanding of gamma delta T cell biology and, because virulent M. bovis infection of cattle represents an excellent model of tuberculosis in humans, contribute to our overall understanding of the role of gamma delta T cells in the mycobacterial-specific immune response.

AB Potato spindle tuber viroid (PSTVd) is a small plant pathogenic circular RNA that does not encode proteins, replicates autonomously, and traffics systemically in infected plants. Long-distance transport occurs by way of the phloem; however, one report in the literature describes the presence of viroid RNA in the xylem ring of potato tubers. In this study, a modified method based on an EDTA-mediated phloem exudation technique was applied for detection of PSTVd in the phloem of infected tomato plants. RT-PCR, nucleic acid sequencing, and Southern blot analyses of RT-PCR products verified the presence of viroid RNA in phloem exudates. In addition, the guttation fluid collected from the leaves of PSTVd-infected tomato plants was analyzed revealing the absence of viroid RNA in the xylem sap. To our knowledge, this is the first report of PSTVd RNA detection in phloem exudates obtained by the EDTA-mediated exudation technique. 0 2014 The Authors. Published by Elsevier B.V.

AB Prenatal and early postnatal environment can persistently alter one's risk of obesity. Environmental effects on hypothalamic developmental epigenetics constitute a likely mechanism underlying such 'developmental programming' of energy balance regulation. To advance our understanding of these processes, it is essential to develop approaches to disentangle the cellular and regional heterogeneity of hypothalamic developmental epigenetics. We therefore performed genome-scale DNA methylation profiling in hypothalamic neurons and non-neuronal cells at postnatal day 0 (P0) and P21 and found, surprisingly, that most of the DNA methylation differences distinguishing these two cell types are established postnatally. In particular, neuron-specific increases in DNA methylation occurred extensively at genes involved in neuronal development. Quantitative bisulfite pyrosequencing verified our methylation profiling results in all 15 regions examined, and expression differences were associated with DNA methylation at several genes. We also identified extensive methylation differences between the arcuate (ARH) and paraventricular nucleus of the hypothalamus (PVH). Integrating these two data sets showed that genomic regions with PVH versus ARH differential methylation strongly overlap with those undergoing neuron-specific increases from P0 to P21, suggesting that these developmental changes occur preferentially in either the ARH or PVH. In particular, neuron-specific methylation increases at the 3' end of Shh localized to the ARH and were positively associated with gene expression. Our data indicate a key role for DNA methylation in establishing the gene expression potential of diverse hypothalamic cell types, and provide the novel insight that early postnatal life is a critical period for cell type-specific epigenetic development in the murine hypothalamus.

AB The resolution of general circulation models (GCMs) is too coarse to assess the site-specific impacts of climate change. Downscaling approaches have been developed to meet this requirement. As the resolution of climate model increases, it is imperative to know whether the finer resolution of regional climate models (RCMs) would result in any improvement of statistical downscaling quality at the station scale for particular downscaling methods. The objective of this study is to assess the effects of climate model resolutions on statistical downscaling quality of precipitation using the generator for point climate change (GPCC) model. The downscaling is conducted across three scales, from GCM, and mid- and high-resolution RCMs to a station scale for two Canadian stations in the Quebec province. Observed precipitation gridded to the corresponding scales is also studied in parallel, totalling six downscaling experiments. The results show that the statistics of downscaled precipitation are somewhat overestimated for the Sept-Iles station for all six downscaling experiments with the relative error of mean daily, monthly, and annual precipitation ranging between 1.1 and 5.0%, between 2.7 and 5.9% and between 0.5 and 6.2%, respectively, but underestimated for the Bonnard station with the relative error ranging between -4.1 and -10.2%, between -3.2 and -13.3%, and between -2.6 and -12.0%, respectively. The number of wet days per year is well preserved with the difference between observed and downscaled data ranging between -2.9 and 6 d across all downscaling experiments and two stations. The quality of downscaled precipitation is similar between using gridded observations and model-simulated data for both stations. Furthermore, there is no noteworthy scale effect on downscaling quality when downscaling climate model output with GPCC, indicating that for regions without RCM projections, high-quality daily series at stations can be derived directly from GCM projections with this particular downscaling model.

AB Continuous monitoring of daily evapotranspiration (ET) at field scale can be achieved by combining thermal infrared remote sensing data information from multiple satellite platforms, given that no single sensor currently exists today with the required spatiotemporal resolution. Here, an integrated approach to field-scale ET mapping is described, combining multi-scale surface energy balance evaluations and a data fusion methodology, namely the Spatial and Temporal Adaptive Reflectance Fusion Model (STARFM), to optimally exploit spatiotemporal characteristics of image datasets collected by the Landsat and Moderate resolution Imaging Spectroradiometer (MODIS) sensors, as well as geostationaiy platforms. Performance of this methodology is evaluated over adjacent irrigated and rainfed fields, since mixed conditions are the most challenging for data fusion procedures, and in two different climatic regions: a semi-arid site in Bushland, TX and a temperate site in Mead, NE. Daytime-total ET estimates obtained for the Landsat overpass dates suggest that the intrinsic model accuracy is consistent across the different test sites (and on the order of 0.5 mm d(-1)) when contemporaneous Landsat imagery at 30-m resolution is available. Comparisons between tower observations and daily ET datastreams, reconstructed between overpasses by fusing Landsat and MODIS estimates, provide a means for assessing the strengths and limitations of the fused product. At the Mead site, the model performed similarly for both irrigated and rainfed fields, with an accuracy of about 0.9 mm d(-1). This similarity in performance is likely due to the relatively large size of the fields (approximate to 50 ha), suggesting that the soil moisture dynamics of the irrigated fields are reasonably well captured at the 1-km MODIS thermal pixel scale. On the other hand, the accuracy of daily retrievals for irrigated fields at the Bushland site was lower than that for the rainfed field (errors of 1.5 and 1.0 mm d(-1), respectively), likely due to the inability of the model to capture ET spikes right after irrigation events for fields substantially smaller than MODIS data resolution. At this site, the irrigated fields were small (approximate to 5 ha) compared to the MODIS pixel size, and sparsely distributed over the landscape, so sporadic contributions to ET from soil evaporation due to irrigation were not captured by the 1-km MODIS ET retrievals. However, due the semiarid environment at Bushland, these irrigation-induced spikes in soil evaporation are not long-lived and these underestimations generally affect the irrigation dates only and they do not seem to influence negatively the estimates at the seasonal scale. ET data fusion is expected to perform better over agricultural areas where irrigation is more spatially continuous, resulting in moisture fluxes that are more uniform at the MODIS pixel scale. Overall, the model accurately reproduces the ET temporal dynamics for all the experimental sites, and is able to capture the main differences that were observed between irrigated and rainfed fields at both daily and seasonal time scales.

AB BACKGROUNDCamelina sativa (CS) is an oilseed crop used for biofuel production. By-products from oil extraction are high in protein and can be used in ruminant rations; more information about their nutritive value is required also considering the antinutrional factor content of the by-products. The aim of this study was to evaluate the nutritive value of CS meal genotypes in comparison with canola.
RESULTSTen CS genotypes and one canola cultivar were evaluated. Meals were obtained from seeds after solvent oil extraction. CS average crude protein (CP) content (gkg(-1) dry matter) was 457. Numerical differences in lysine and sulfur amino acid content were observed among CS genotypes. Glucosinolate (mmolkg(-1)) content was higher for CS (23.1) than canola (7.2). Sinapine content (gkg(-1)) was lower for CS (2.79) than for canola (4.32). Differences were observed among CS genotypes for rumen undegraded protein (RUP). Average RUP (gkg(-1) CP) was 316 for CS and 275 for canola.
CONCLUSIONSCS meal has potential for use in ruminant rations as a high-quality protein source. In vivo studies are needed to compare CS with other protein sources used in cattle rations. Implementation of breeding programs for improved meal quality is recommend. (c) 2013 Society of Chemical Industry

AB The role of non-covalent interactions in the formation of visco-elastic material from zein was investigated. Hydrophobic interactions were evaluated through the addition of various salts from the Hofmeister series. Urea, ethanol, and beta mercaptoethanol (beta-ME) were used to evaluate the effects of protein denaturation and disulfide bonds on zein's ability to form a visco-elastic material. The addition of NaI and NaSCN altered the properties of visco-elastic materials made from zein, making them softer and more extensible, as did urea and ethanol. The addition of NaCl and Na2SO4 negatively impacted the ability of zein to from a visco-elastic material and at higher concentrations completely disrupted the formation of visco-elastic material. These results indicate that manipulating non-covalent interactions in zein can alter and in some cases, completely disrupt the formation of a visco-elastic material. Specifically this may be due to disruption of hydrophobic interactions within individual zein proteins or interactions between proteins. The reducing agent beta-ME had little effect on zein's ability to form a visco-elastic material. Therefore, the visco-elastic properties of zein arise as a result of non-covalent interactions.

AB Background: Arabinanases are key enzymes involved in hemicellulose degradation. Results: Crystallographic, mutational, and biochemical assays of three arabinanases reveal the molecular mechanisms governing their catalysis and activation. Conclusion: Accessory domain and metal ion are essential for catalysis. Structural adaptations in the catalytic interface confer unique action modes to ruminal arabinanases. Significance: This work provides new molecular strategies for arabinan hydrolysis.
Arabinanases (ABNs, EC 3.2.1.99) are promising catalysts for environmentally friendly biomass conversion into energy and chemicals. These enzymes catalyze the hydrolysis of the -1,5-linked l-arabinofuranoside backbone of plant cell wall arabinans releasing arabino-oligosaccharides and arabinose, the second most abundant pentose in nature. In this work, new findings about the molecular mechanisms governing activation, functional differentiation, and catalysis of GH43 ABNs are presented. Biophysical, mutational, and biochemical studies with the hyperthermostable two-domain endo-acting ABN from Thermotoga petrophila (TpABN) revealed how some GH43 ABNs are activated by calcium ions via hyperpolarization of the catalytically relevant histidine and the importance of the ancillary domain for catalysis and conformational stability. On the other hand, the two GH43 ABNs from rumen metagenome, ARN2 and ARN3, presented a calcium-independent mechanism in which sodium is the most likely substituent for calcium ions. The crystal structure of the two-domain endo-acting ARN2 showed that its ability to efficiently degrade branched substrates is due to a larger catalytic interface with higher accessibility than that observed in other ABNs with preference for linear arabinan. Moreover, crystallographic characterization of the single-domain exo-acting ARN3 indicated that its cleavage pattern producing arabinose is associated with the chemical recognition of the reducing end of the substrate imposed by steric impediments at the aglycone-binding site. By structure-guided rational design, ARN3 was converted into a classical endo enzyme, confirming the role of the extended Arg(203)-Ala(230) loop in determining its action mode. These results reveal novel molecular aspects concerning the functioning of GH43 ABNs and provide new strategies for arabinan degradation.

AB Background: Wheat glutenin polymers are made up of two main subunit types, the high- (HMW-GS) and low- (LMW-GS) molecular weight subunits. These latter are represented by heterogeneous proteins. The most common, based on the first amino acid of the mature sequence, are known as LMW-m and LMW-s types. The mature sequences differ as a consequence of three extra amino acids (MET-) at the N-terminus of LMW-m types. The nucleotide sequences of their encoding genes are, however, nearly identical, so that the relationship between gene and protein sequences is difficult to ascertain.
It has been hypothesized that the presence of an asparagine residue in position 23 of the complete coding sequence for the LMW-s type might account for the observed three-residue shortened sequence, as a consequence of cleavage at the asparagine by an asparaginyl endopeptidase.
Results: We performed site-directed mutagenesis of a LMW-s gene to replace asparagine at position 23 with threonine and thus convert it to a candidate LMW-m type gene. Similarly, a candidate LMW-m type gene was mutated at position 23 to replace threonine with asparagine. Next, we produced transgenic durum wheat (cultivar Svevo) lines by introducing the mutated versions of the LMW-m and LMW-s genes, along with the wild type counterpart of the LMW-m gene.
Proteomic comparisons between the transgenic and null segregant plants enabled identification of transgenic proteins by mass spectrometry analyses and Edman N-terminal sequencing.
Conclusions: Our results show that the formation of LMW-s type relies on the presence of an asparagine residue close to the N-terminus generated by signal peptide cleavage, and that LMW-GS can be quantitatively processed most likely by vacuolar asparaginyl endoproteases, suggesting that those accumulated in the vacuole are not sequestered into stable aggregates that would hinder the action of proteolytic enzymes. Rather, whatever is the mechanism of glutenin polymer transport to the vacuole, the proteins remain available for proteolytic processing, and can be converted to the mature form by the removal of a short N-terminal sequence.

AB Background: Cytosolic Hsp70 is a ubiquitous molecular chaperone that is involved in responding to a variety of cellular stresses. A major function of Hsp70 is to prevent the aggregation of denatured proteins by binding to exposed hydrophobic regions and preventing the accumulation of amorphous aggregates. To gain further insight into the functional redundancy and specialisation of the highly homologous yeast Hsp70-Ssa family we expressed each of the individual Ssa proteins as the sole source of Hsp70 in the cell and assessed phenotypic differences in prion propagation and stress resistance. Additionally we also analysed the global gene expression patterns in yeast strains expressing individual Ssa proteins, using microarray and RT-qPCR analysis.
Results: We confirm and extend previous studies demonstrating that cells expressing different Hsp70-Ssa isoforms vary in their ability to propagate the yeast [PSI+] prion, with Ssa3 being the most proficient. Of the four Ssa family members the heat inducible isoforms are more proficient in acquiring thermotolerance and we show a greater requirement than was previously thought, for cellular processes in addition to the traditional Hsp104 protein disaggregase machinery, in acquiring such thermotolerance. Cells expressing different Hsp70-Ssa isoforms also display differences in phenotypic response to exposure to cell wall damaging and oxidative stress agents, again with the heat inducible isoforms providing better protection than constitutive isoforms. We assessed global transcriptome profiles for cells expressing individual Hsp70-Ssa isoforms as the sole source of cytosolic Hsp70, and identified a significant difference in cellular gene expression between these strains. Differences in gene expression profiles provide a rationale for some phenotypic differences we observed in this study. We also demonstrate a high degree of correlation between microarray data and RT-qPCR analysis for a selection of genes.
Conclusions: The Hsp70-Ssa family provide both redundant and variant-specific functions within the yeast cell. Yeast cells expressing individual members of the Hsp70-Ssa family as the sole source of Ssa protein display differences in global gene expression profiles. These changes in global gene expression may contribute significantly to the phenotypic differences observed between the Hsp70-Ssa family members.

AB Ecological specialization should minimize niche overlap, yet herbivorous neotropical flies (Blepharoneura) and their lethal parasitic wasps (parasitoids) exhibit both extreme specialization and apparent niche overlap in host plants. From just two plant species at one site in Peru, we collected 3636 flowers yielding 1478 fly pupae representing 14 Blepharoneura fly species, 18 parasitoid species (14 Bellopius species), and parasitoid-host associations, all discovered through analysis of molecular data. Multiple sympatric species specialize on the same sex flowers of the same fly host-plant species-which suggests extreme niche overlap; however, niche partitioning was exposed by interactions between wasps and flies. Most Bellopius species emerged as adults from only one fly species, yet evidence from pupae (preadult emergence samples) show that most Bellopius also attacked additional fly species but never emerged as adults from those flies.

AB Motor neurons, which relay neural commands to drive skeletal muscle movements, encompass types ranging from "slow" to "fast," whose biophysical properties govern the timing, gradation, and amplitude of muscle force. Here we identify the noncanonical Notch ligand Delta-like homolog 1 (Dlk1) as a determinant of motor neuron functional diversification. Dlk1, expressed by similar to 30% of motor neurons, is necessary and sufficient to promote a fast biophysical signature in the mouse and chick. Dlk1 suppresses Notch signaling and activates expression of the K+ channel subunit Kcng4 to modulate delayed-rectifier currents. Dlk1 inactivation comprehensively shifts motor neurons toward slow biophysical and transcriptome signatures, while abolishing peak force outputs. Our findings provide insights into the development of motor neuron functional diversity and its contribution to the execution of movements.

AB Phenotype in multicellular organisms is the consequence of dynamic metabolic events that occur in a spatially dependent fashion. This spatial and temporal complexity presents challenges for investigating metabolism; creating a need for improved methods that effectively probe biochemical events such as amino acid biosynthesis. Isotopic labeling can provide a temporal-spatial recording of metabolic events through, for example, the description of enriched amino acids in the protein pool. Proteins are therefore an important readout of metabolism and can be assessed with modern mass spectrometers. We compared the measurement of isotopic labeling in MS2 spectra obtained from tandem mass spectrometry under either higher energy collision dissociation (HCD) or collision induced dissociation (CID) at varied energy levels. Developing soybean embryos cultured with or without C-13-labeled substrates, and Escherichia coli MG1655 enriched by feeding 7% uniformly labeled glucose served as a source of biological material for protein evaluation. CID with low energies resulted in a disproportionate amount of heavier isotopologues remaining in the precursor isotopic distribution. HCD resulted in fewer quantifiable products; however deviation from predicted distributions were small relative to the CID-based comparisons. Fragment ions have the potential to provide information on the labeling of amino acids in peptides, but our results indicate that without further development the use of this readout in quantitative methods such as metabolic flux analysis is limited.

AB Cotton's exceptional softness, breathability, and absorbency have made it America's best-selling textile fiber; however, cotton textiles are generally more combustible than their synthetic counterparts. In this study, a continuous layer-by-layer self-assembly technique was used to deposit polymer clay nanocoatings on cotton fabrics to enhance their flame retardancy. Alternating layers of positively charged branched polyethylenimine (BPEI) with urea and diammonium phosphate and negatively charged clay nanoparticles were continuously applied to the fabrics in a single process without rinsing. The morphology and flame-retardant properties of the coated fabrics were characterized using scanning electron microscopy (SEM) and a variety of flammability tests. The treated fabrics exhibited improved thermal stability, as evidenced by increased ignition times and lower heat release rates. The results of this study show that flame-retardant nanocoatings can be readily applied to textile fabrics using a continuous process that is ideal for commercial and industrial applications.

AB To mitigate damage from the fungal sugarcane pathogen brown rust (Puccinia melanocephala), a Section 18 Emergency Use Label was put in place by the United States Environmental Protection Agency (U.S. EPA) for the application of pyraclostrobin (trade name Headline SC, produced by BASF, Research Triangle Park, NC) on sugarcane in 2008. To assess the dynamics of this fungicide in Louisiana soil, samples (n = 24) from a non-treated field were spiked with pyraclostrobin (3.1 mu g g(-1)) and analyzed in laboratory conditions over the course of 63 days using quick, easy, cheap, effective, rugged, and safe (QuEChERS) dispersive solid-phase extraction/high-performance liquid chromatography with ultraviolet visible detection (dSPE/HPLC-UV). Modeling was performed using Microsoft Excel to predict DTx values. Pyraclostrobin was found to follow lbiphasic kinetics with DT50 and DT90 values of 60 and 282 days, suggesting that it is moderately persistent to persistent in soils. Wash-off studies on sugarcane indicate that very little fungicide is in the wash-off after 48 h. If applied to sugarcane according to label recommendations, the fungicide should have minimal dissipation from rainfall events.

AB Lipoyl glycerides were synthesized by enzymatic transesterification of lipoic acid with high-oleic sunflower oil in 2-methyl-2-butanol solvent. The synthesis gave a crude product mixture comprising unreacted lipoic acid, free fatty acids, and several lipoyl glyceride structures of varying lipoic acid substitution. A more purified product mixture, devoid of unreacted lipoic acid and free fatty acids, was obtained in 61% yield. The crude and purified product mixtures were thoroughly characterized and their components positively identified. The tribological properties of the product mixtures were further investigated using a variety of methods. The product mixtures displayed significantly Unproved oxidation stability, cold-flow, and extreme pressure properties over those of the parent high-oleic sunflower oil. The extreme pressure results for the neat products showed a higher weld point for the crude than for the purified mixture. This was attributed to differences in the chemical properties of the components in the two product mixtures.

Meyeraepalpus delfinadae Smiley et al., is reinstated based on new material and an analysis of its phylogenetic relationships. Crossipalpus muellerianae Smiley et al., Crossipalpus verticillatae Smiley et al., and Tegopalpus conicus Womersley are redescribed and rediagnosed from the original type specimens and newly collected material; and Chaudhripalpus creelae (Smiley et al.), Magdalenapalpus strandtmanni (Smiley et al.) and Philippipalpus agohoi Corpuz-Raros are redescribed and rediagnosed from type material only. All flat mite species were host-specific. Up to three species of flat mite were collected from a single she-oak species. Leg setation and ontogeny are reviewed for the taxa studied. A key to Tenuipalpidae from Casuarinaceae is provided. A phylogeny of the subfamily Tegopalpinae found the following relationships: Meyeraepalpus (Australopalpus, Crossipalpus, Palpipalpus (Magdalenapalpus (Philippipalpus (Chaudhripalpus + Tegopalpus)))). Our preliminary analysis of the Tegopalpinae suggested the group is monophyletic and its sister group is Phytoptipalpus.

AB The reniform nematode, Rotylenchulus reniformis, is a damaging semi-endoparasitic pathogen of more than 300 plant species. Transcriptome sequencing of R. reniformis parasitic females revealed an enrichment for sequences homologous to C-type lectins (CTLs), an evolutionarily ancient family of Ca+2-dependent carbohydrate-binding proteins that are involved in the innate immune response. To gain further insight as to the potential role of CTLs in facilitating plant parasitism by R. reniformis, we performed a comprehensive assessment of the CTL gene family. 5'- and 3'-RACE experiments identified a total of 11 R. reniformis CTL transcripts (Rr-ctl-1 through Rr-ctl-11) that ranged in length from 1083 to 1194 bp and showed 93-99% identity with one another. An alignment of cDNA and genomic sequences revealed three introns with the first intron residing within the 5'-untranslated region. BLAST analyses showed the closest homologs belonging to the parasitic nematodes Heligmosomoides polygyrus and Heterodera glycines. Rr-ctl-1, -2, and -3 were expressed throughout the R. reniformis life cycle; whereas, the remaining Rr-ctl genes showed life stage-specific expression. Quantitative real time RT-PCR determined that Rr-ctl transcripts were 839-fold higher in sedentary female nematodes than the next most abundant life stage. Predicted Rr-CTL peptides ranged from 301 to 338 amino acids long, possessed an N-terminal signal peptide for secretion, and contained a conserved CLECT domain, including the mannose-binding motifs EPN and EPD and the conserved WND motif that is required for binding Ca+2. In addition, Rr-CTL peptides harbored repeats of a novel 17-mer motif within their C-terminus that showed similarity to motifs associated with bacterial ice nucleation proteins. In situ hybridization of Rr-ctl transcripts within sedentary females showed specific accumulation within the hypodermis of the body regions exposed to the soil environment; those structures embedded within the root during parasitism did not show Rr-ctl expression. A phylogenetic analysis of the Rr-CTL CLECT domain with homologous domains from other nematode species suggested that CTLs from animal- and plant-parasitic genera may have evolved in order to play an active role in the parasitic process.

TI The Ca2+/H+ antiporter TMEM165 expression, localization in the
developing, lactating and involuting mammary gland parallels the

AB Plasma membrane Ca2+-ATPase 2 (PMCA2) knockout mice showed that similar to 60% of calcium in milk is transported across the mammary cells apical membrane by PMCA2. The remaining milk calcium is thought to arrive via the secretory pathway through the actions of secretory pathway Ca2+-ATPase's 1 and/or 2 (SPCA1 and 2). However, another secretory pathway calcium transporter was recently described. The question becomes whether this Golgi Ca2+/H+ antiporter (TMEM165) is expressed sufficiently in the Golgi of lactating mammary tissue to be a relevant contributor to secretory pathway mammary calcium transport. TMEM165 shows marked expression on day one of lactation when compared to timepoints prepartum. At peak lactation TMEM165 expression was 25 times greater than that of early pregnancy. Forced cessation of lactation resulted in a rapid similar to 50% decline in TMEM165 expression at 24 h of involution and TMEM165 expression declined 95% at 96 h involution. It is clear that the timing, magnitude of TMEM165 expression and its Golgi location supports a role for this Golgi Ca2(+)/H+ antiporter as a contributor to mammary Golgi calcium transport needs, in addition to the better-characterized roles of SPCA1&2.

TI Geographical Gradient of the eIF4E Alleles Conferring Resistance to
Potyviruses in Pea (Pisum) Germplasm

AB Background: The eukaryotic translation initiation factor 4E was shown to be involved in resistance against several potyviruses in plants, including pea. We combined our knowledge of pea germplasm diversity with that of the eIF4E gene to identify novel genetic diversity.
Methodology/Principal findings: Germplasm of 2803 pea accessions was screened for eIF4E intron 3 length polymorphism, resulting in the detection of four eIF4E(A-B-C-S) variants, whose distribution was geographically structured. The eIF4E(A) variant conferring resistance to the P1 PSbMV pathotype was found in 53 accessions (1.9%), of which 15 were landraces from India, Afghanistan, Nepal, and 7 were from Ethiopia. A newly discovered variant, eIF4E(B), was present in 328 accessions (11.7%) from Ethiopia (29%), Afghanistan (23%), India (20%), Israel (25%) and China (39%). The eIF4E(C) variant was detected in 91 accessions (3.2% of total) from India (20%), Afghanistan (33%), the Iberian Peninsula (22%) and the Balkans (9.3%). The eIF4E(S) variant for susceptibility predominated as the wild type. Sequencing of 73 samples, identified 34 alleles at the whole gene, 26 at cDNA and 19 protein variants, respectively. Fifteen alleles were virologically tested and 9 alleles (eIF4E(A-1-2-3-4-5-6-7), eIF4E(B-1), eIF4E(C-2)) conferred resistance to the P1 PSbMV pathotype.
Conclusions/Significance: This work identified novel eIF4E alleles within geographically structured pea germplasm and indicated their independent evolution from the susceptible eIF4E(S1) allele. Despite high variation present in wild Pisum accessions, none of them possessed resistance alleles, supporting a hypothesis of distinct mode of evolution of resistance in wild as opposed to crop species. The Highlands of Central Asia, the northern regions of the Indian subcontinent, Eastern Africa and China were identified as important centers of pea diversity that correspond with the diversity of the pathogen. The series of alleles identified in this study provides the basis to study the co-evolution of potyviruses and the pea host.

AB The aim of this study was to examine two benzo analogs, octylgallate (OG) and veratraldehyde (VT), as antifungal agents against strains of Aspergillus parasiticus and A.flavus (toxigenic or atoxigenic). Both toxigenic and atoxigenic strains used were capable of producing kojic acid, another cellular secondary product. A. fumigatus was used as a genetic model for this study. When applied independently, OG exhibits considerably higher antifungal activity compared to VT. The minimum inhibitory concentrations (MICs) of OG were 0.3-0.5 mM, while that of VT were 3.0-5.0 mM in agar plate-bioassays. OG or VT in concert with the fungicide kresoxim methyl (Kre-Me; strobilurin) greatly enhanced sensitivity of Aspergillus strains to Kre-Me. The combination with OG also overcame the tolerance of A. fumigatus mitogen-activated protein kinase (MARK) mutants to Kre-Me. The degree of compound interaction resulting from chemosensitization of the fungi by OG was determined using checkerboard bioassays, where synergistic activity greatly lowered MICs or minimum fungicidal concentrations. However, the control chemosensitizer benzohydroxamic acid, an alternative oxidase inhibitor conventionally applied in concert with strobilurin, did not achieve synergism. The level of antifungal or chemosensitizing activity was also "compound strain" specific, indicating differential susceptibility of tested strains to OG or VT, and/or heat stress. Besides targeting the antioxidant system, OG also negatively affected the cell wall-integrity pathway, as determined by the inhibition of Saccharomyces cerevisiae cell wall-integrity MARK pathway mutants. We concluded that certain benzo analogs effectively inhibit fungal growth. They possess chemosensitizing capability to increase efficacy of Kre-Me and thus, could reduce effective dosages of strobilurins and alleviate negative side effects associated with current antifungal practices. OG also exhibits moderate antiaflatoxigenic activity.

AB Arboreal herbivory is rare among mammals. The few species with this lifestyle possess unique adaptions to overcome size-related constraints on nutritional energetics. Sloths are folivores that spend most of their time resting or eating in the forest canopy. A three-toed sloth will, however, descend its tree weekly to defecate, which is risky, energetically costly and, until now, inexplicable. We hypothesized that this behaviour sustains an ecosystem in the fur of sloths, which confers cryptic nutritional benefits to sloths. We found that the more specialized three-toed sloths harboured more phoretic moths, greater concentrations of inorganic nitrogen and higher algal biomass than the generalist two-toed sloths. Moth density was positively related to inorganic nitrogen concentration and algal biomass in the fur. We discovered that sloths consumed algae from their fur, which was highly digestible and lipid-rich. By descending a tree to defecate, sloths transport moths to their oviposition sites in sloth dung, which facilitates moth colonization of sloth fur. Moths are portals for nutrients, increasing nitrogen levels in sloth fur, which fuels algal growth. Sloths consume these algae-gardens, presumably to augment their limited diet. These linked mutualisms between moths, sloths

AB Chilling temperatures (<10 C) may cause damages in cucumber plants (Cucumis sativus L) during winter and early spring seasons. Inheritance of chilling injury in U.S. processing cucumber is controlled by cytoplasmic (maternally) and nuclear factors. To understand inheritance of chilling injury in Korean market-type cucumber, reciprocal crosses between chilling tolerant (CT1) and susceptible (CT4) lines produced F1 (CT1 x CT4) and F-1 (CT4 x CT1) progenies. Reciprocal F2 (CT1 x CT4) and F-2 (CT4 x CT1) populations were subsequently derived. Seedlings in the first true leaf stage were subjected to 4 C for 8 h (08:00 to 16:00) and damage level was assessed visually using 1 (no damage) to 5 (severe damage) rating scale. Means of damage rating for reciprocal F1 (CT1 x CT4) and F-1 (CT4 x CT1) progenies were 1.1 and 1.1, respectively. This indicates that tolerance for chilling stress at 4 C in this germplasm is dominant. However, means of damage for F-2 (CTI x CT4) progenies and F-2 (CT4 x CT1) progenies were 3.2 and 1.2, respectively. These data indicate that genetic control of chilling injury in these progenies is paternal. Based on the data, we hypothesize that line CT1 possesses a dominant nuclear factor that conditions chilling tolerance in both reciprocal Els and a paternal factor(s) that lead chilling tolerance only in F-2 (CT4 x CTI). These putative nuclear and paternal genetic factors are designated as Ch-1 and Ch-p, respectively. (C) 2014 Elsevier B.V. All rights reserved.

AB Lilium longiflorum cv. Nellie White plants were transformed with either the bar-uidA fusion gene or the nptII and uidA genes and grown for two seasons in the greenhouse and outdoors in containers. All transgenes were under control of the CaMV 35S promoter. During the first year there was no difference in bar protein level between plants grown in the greenhouse and outdoors, but the second year two of the seven transgenic plant lines grown outdoors showed a significantly higher level of the bar protein than plants grown in the greenhouse. The relative level of bar protein expression between all seven transgenic plant lines remained the same for lilies grown in the greenhouse and outdoors during two growing seasons. One plant line contained the nptII gene, and nptII protein expression was comparable when plants were grown in the greenhouse or outdoors for two seasons. Four plant lines expressed GUS as determined by histochemical staining of their leaves. Three of these four plant lines showed dark blue staining along the cut edges of the leaf when plants were grown either in the greenhouse or outdoors for both seasons. The fourth plant line showed either dark blue staining along the cut edge of the leaf or small, light blue spots on parts of the leaf depending on the plant stained. Expression of the three genes was confirmed using semi-quantitative RT-PCR. Published by Elsevier B.V.

AB The recent expansion of Aedes albopictus, a day-biting mosquito, to densely inhabited areas in the northeastern Atlantic states of the USA has dramatically increased the problem that mosquitoes create for urban and suburban residents. We quantified the impact of mosquitoes on residents' quality of life within the context of a comprehensive area-wide integrated pest management program to control Ae. albopictus in two counties (Mercer and Monmouth) in New Jersey. We interviewed residents of 121 randomly selected households in both counties between October and November 2010. We asked residents about their experience with mosquitoes in their neighborhood and the importance of the ability to relax outdoors without mosquitoes compared to other neighborhood characteristics (1 = not important, 5 = extremely important). We rated residents' utility based on paired comparisons to known states from the EuroQol health description system. The majority (54.6%) of respondents considered mosquitoes to be a problem. Respondents reported an average of 7.1 mosquito bites in a typical week during that summer. Mosquitoes prevented 59.5% of residents from enjoying their outdoor activities at least to some extent. Residents rated the mosquito acceptability (mean +/- standard deviation) during that summer on a scale of 0 (mosquito invasion) to 100 (no mosquitoes) at 56.7 +/- 28.7, and their overall utility at 0.87 +/- 0.03. This is comparable to living with up to two risk factors for diabetes (i.e., abdominal obesity, body mass index of 28 or more, reported cholesterol problems, diagnosis of hypertension, or history of cardiovascular disease) or women experiencing menstrual disorders. Respondents rated the importance of enjoying outdoor activities without mosquitoes (4.69 +/- 0.80) comparable to that of neighborhood safety (4.74 +/- 0.80) and higher than that of a clean neighborhood (4.59 +/- 0.94). In conclusion, New Jersey residents reported that mosquitoes decreased their utility by 0.13, comparable to the loss from worrisome health risk factors, underscoring the importance of controlling this problem.

AB Endosulfan (6,7,8, 9,10,10-hexachloro-1,5,5a,6,9,9a-hexahydro-6,9-methano-2,4,3-benzodioxathiepine-3-oxide) is a broad-spectrum, organochlorine insecticide used on numerous crops since the 1950s. It is has been identified as a persistent organic pollutant (POP) due to its persistence, bioaccumulation, long-range transport, and adverse effects to human health and aquatic ecosystems; it will be phased out in the United States in 2016. Endosulfan consists of two diastereomers, alpha and beta; alpha-endosulfan exists as two asymmetrical, twist-chair enantiomers which interchange, while beta-endosulfan has a symmetrical-chair conformation. beta-Endosulfan has been shown to isomerize to a-endosulfan. Here we document the previously proposed isomerization mechanism using temperature-dependent Raman (TDR) spectroscopy. The bending frequencies in the fingerprint region were assigned to specific bonds. Changes in the signal intensity as a function of temperature were used to identify detailed ring movements and thus conversion of beta to alpha. These movements cannot occur simultaneously nor symmetrically, precluding conversion of alpha-endosulfan to beta-endosulfan.

AB Fusarium verticillioides produces fumonisin mycotoxins during the colonization of maize, and fumonisin B-1 (FB1) production is necessary for manifestation of maize seedling blight disease. The objective of this study was to address FB1 mobility and accumulation in seedlings to determine if proximal infection by F. verticillioides is necessary for FB1 accumulation. Taking advantage of an aconidial mutant known to have limited capability for seedling infection, tissue and soil samples were analyzed to compare wild-type F. verticillioides against the mutant. Inoculation with either strain caused accumulation of FB1 in the first and second leaves, but the mutants were unable to colonize aerial tissues. FB1, FB2, and FB3 were detected in the soil and seedling roots, but only FB1 was detected in the leaves of any treatment. These data suggest root infection by F. verticillioides is necessary for accumulation of FB1 in leaves, but the mechanism for accumulation does not require colonization of the leaf.

AB Next generation sequencing (RNA-seq) technology was used to evaluate the effects of the Ligon lintless-2 (Li-2) short fiber mutation on transcriptomes of both subgenomes of allotetraploid cotton (Gossypium hirsutum L.) as compared to its near-isogenic wild type. Sequencing was performed on 4 libraries from developing fibers of Li-2 mutant and wild type near-isogenic lines at the peak of elongation followed by mapping and PolyCat categorization of RNA-seq data to the reference D-5 genome (G. raimondii) for homeologous gene expression analysis. The majority of homeologous genes, 83.6% according to the reference genome, were expressed during fiber elongation. Our results revealed: 1) approximately two times more genes were induced in the A(T) subgenome comparing to the D-T subgenome in wild type and mutant fiber; 2) the subgenome expression bias was significantly reduced in the Li-2 fiber transcriptome; 3) Li-2 had a significantly greater effect on the D-T than on the A(T) subgenome. Transcriptional regulators and cell wall homeologous genes significantly affected by the Li-2 mutation were reviewed in detail. This is the first report to explore the effects of a single mutation on homeologous gene expression in allotetraploid cotton. These results provide deeper insights into the evolution of allotetraploid cotton gene expression and cotton fiber development.

AB This study investigated how lidar-derived vegetation indices, disturbance history from Landsat time series (LTS) imagery, plot location accuracy, and plot size influenced accuracy of statistical spatial models (nearest-neighbor imputation maps) of forest vegetation composition and structure. Nearest-neighbor (NN) imputation maps were developed for 539,000 ha in the central Oregon Cascades, USA. Mapped explanatory data included tasseled-cap indices and disturbance history metrics (year, magnitude, and duration of disturbance) from LTS imagery, lidar-derived vegetation metrics, climate, topography, and soil parent material. Vegetation data from USDA Forest Service forest inventory plots was summarized at two plot sizes (plot and subplot) and geographically located with two levels of accuracy (standard and improved). Maps of vegetation composition and structure were developed with the Gradient Nearest Neighbor (GNN) method of NN imputation using different combinations of explanatory variables, plot spatial resolution, and plot positional accuracy. Lidar vegetation indices greatly improved predictions of live tree structure, moderately improved predictions of snag density and down wood volume, but did not consistently improve species predictions. LTS disturbance metrics improved predictions of forest structure, but not to the degree of lidar indices, while also improving predictions of many species. Absence of disturbance attribution (i.e. disturbance type such as fire or timber harvest) in LTS disturbance metrics may have limited our ability to predict forest structure. Absence of corrected lidar intensity values may also have lowered accuracy of snag and species predictions. However, LTS disturbance attribution and lidar corrected intensity values may not be able to overcome fundamental limitations of remote sensing for predicting snags and down wood that are obscured by the forest canopy. Improved GPS plot locations had little influence on map accuracy, and we suggest under what conditions improved GPS plot locations may or may not improve the accuracy of predictive maps that link remote sensing with forest inventory plots. Subplot NN imputation maps had much lower accuracy compared to maps generated using response variables from larger whole plots. No single map had optimal results for every mapped variable, suggesting map users and developers need to prioritize what forest vegetation attributes are most important for any given map application.

AB Many microbial, fungal, or oomcyete populations violate assumptions for population genetic analysis because these populations are clonal, admixed, partially clonal, and/or sexual. Furthermore, few tools exist that are specifically designed for analyzing data from clonal populations, making analysis difficult and haphazard, We developed the R package poppr providing unique tools for analysis of data from admixed, clonal, mixed, and/or sexual populations. Currently, poppr can be used for dominant/codominant and haploid/diploid genetic data. Data can be imported from several formats including GenAlEx formatted text files and can be analyzed on a user-defined hierarchy that includes unlimited levels of subpopulation structure and clone censoring. New functions include calculation of Bruvo's distance for microsatellites, batch-analysis of the index of association with several indices of genotypic diversity sity, and graphing including dendrograrns with bootstrap support and minimum spanning networks. While functions for genotypic diversity and clone censoring are specific for clonal populations, several functions found in poppr are also valuable to analysis of any populations. A manual with documentation and examples is provided. Poppr is open source and major releases are available on CRAN: http://cran.r-project.org/package=poppr. More supporting documentation and tutorials can be found under 'resources' at: http://grunwaldlab.cgrb.oregonstate.edu/.

AB The need for large sample sizes to train, calibrate, and validate remote-sensing products has driven an emphasis towards rapid, and in many cases qualitative, field methods. Double-sampling is an option for calibrating less precise field measurements with data from a more precise method collected at a subset of sampling locations. While applicable to the creation of training and validation datasets for remote-sensing products, double-sampling has rarely been used in this context. Our objective was to compare vegetation indicators developed from a rapid qualitative (i.e. ocular estimation) field protocol with the quantitative field protocol used by the Bureau of Land Management's Assessment, Inventory and Monitoring (AIM) programme to determine whether double-sampling could be used to adjust the qualitative estimates to improve the relationship between rapidly collected field data and high-resolution satellite imagery. We used beta regression to establish the relationship between the quantitative and qualitative estimates of vegetation cover from 50 field sites in the Piceance Basin of northwestern Colorado, USA. Using the defined regression models for eight vegetation indicators we adjusted the qualitative estimates and compared the results, along with the original measurements, to 5 m-resolution RapidEye satellite imagery. We found good correlation between quantitative and ocular estimates for dominant site components such as shrub cover and bare ground, but low correlations for minor site components (e.g. annual grass cover) or indicators where observers were required to estimate over multiple life forms (e.g. total canopy cover). Using the beta-regression models to adjust the qualitative estimates with the quantitative data significantly improved correlation with the RapidEye imagery for most indicators. As a means of improving training data for remote-sensing projects, double-sampling should be used where a strong relationship exists between quantitative and qualitative field techniques. Accordingly, ocular techniques should be used only when they can generate reliable estimates of vegetation cover.

TI Genome-wide association and genomic prediction for host response to
porcine reproductive and respiratory syndrome virus infection
SO GENETICS SELECTION EVOLUTION
LA English
DT Article
ID REPLICATION; GAMMA
AB Background: Host genetics has been shown to play a role in porcine reproductive and respiratory syndrome (PRRS), which is the most economically important disease in the swine industry. A region on Sus scrofa chromosome (SSC) 4 has been previously reported to have a strong association with serum viremia and weight gain in pigs experimentally infected with the PRRS virus (PRRSV). The objective here was to identify haplotypes associated with the favorable phenotype, investigate additional genomic regions associated with host response to PRRSV, and to determine the predictive ability of genomic estimated breeding values (GEBV) based on the SSC4 region and based on the rest of the genome. Phenotypic data and 60 K SNP genotypes from eight trials of similar to 200 pigs from different commercial crosses were used to address these objectives.
Results: Across the eight trials, heritability estimates were 0.44 and 0.29 for viral load (VL, area under the curve of log-transformed serum viremia from 0 to 21 days post infection) and weight gain to 42 days post infection (WG), respectively. Genomic regions associated with VL were identified on chromosomes 4, X, and 1. Genomic regions associated with WG were identified on chromosomes 4, 5, and 7. Apart from the SSC4 region, the regions associated with these two traits each explained less than 3% of the genetic variance. Due to the strong linkage disequilibrium in the SSC4 region, only 19 unique haplotypes were identified across all populations, of which four were associated with the favorable phenotype. Through cross-validation, accuracies of EBV based on the SSC4 region were high (0.55), while the rest of the genome had little predictive ability across populations (0.09).
Conclusions: Traits associated with response to PRRSV infection in growing pigs are largely controlled by genomic regions with relatively small effects, with the exception of SSC4. Accuracies of EBV based on the SSC4 region were high compared to the rest of the genome. These results show that selection for the SSC4 region could potentially reduce the effects of PRRS in growing pigs, ultimately reducing the economic impact of this disease.

AB Background: Signatures of selection are regions in the genome that have been preferentially increased in frequency and fixed in a population because of their functional importance in specific processes. These regions can be detected because of their lower genetic variability and specific regional linkage disequilibrium (LD) patterns.
Methods: By comparing the differences in regional LD variation between dairy and beef cattle types, and between indicine and taurine subspecies, we aim at finding signatures of selection for production and adaptation in cattle breeds. The VarLD method was applied to compare the LD variation in the autosomal genome between breeds, including Angus and Brown Swiss, representing taurine breeds, and Nelore and Gir, representing indicine breeds. Genomic regions containing the top 0.01 and 0.1 percentile of signals were characterized using the UMD3.1 Bos taurus genome assembly to identify genes in those regions and compared with previously reported selection signatures and regions with copy number variation.
Results: For all comparisons, the top 0.01 and 0.1 percentile included 26 and 165 signals and 17 and 125 genes, respectively, including TECRL, BT.23182 or FPPS, CAST, MYOM1, UVRAG and DNAJA1.
Conclusions: The VarLD method is a powerful tool to identify differences in linkage disequilibrium between cattle populations and putative signatures of selection with potential adaptive and productive importance.

TI Effects of Streamflow Diversion on a Fish Population: Combining
Empirical Data and Individual-Based Models in a Site-Specific Evaluation

AB Resource managers commonly face the need to evaluate the ecological consequences of specific water diversions of small streams. We addressed this need by conducting 4years of biophysical monitoring of stream reaches above and below a diversion and applying two individual-based models of salmonid fish that simulated different levels of behavioral complexity. The diversion of interest captured about 24% of streamflow between June and October but had little or no effect over the remainder of the year. The change in biomass of Rainbow Trout Oncorhynchus mykiss and steelhead (anadromous Rainbow Trout) over the dry season (June-October) favored the upstream control over the downstream diversion reach over 4years (2008-2011). Dry-season growth did not differ consistently between the two reaches but did exhibit substantial annual variation. Longer-term observations revealed that in both reaches most fish growth occurred outside the period of dry-season diversion. After calibration to the upstream control reach, both individual-based models predicted the observed difference in fish biomass between control and diversion reaches at the ends of the dry seasons. Both models suggested the difference was attributable in part to differences in habitat structure unrelated to streamflow that favored the upstream reach. The two models both also reproduced the large seasonal differences in growth, small differences between reaches in individual growth, and natural distributions of growth among individuals. Both the empirical data and simulation modeling suggested that the current level of diversion does not threaten the persistence of the salmonid population. In multiyear simulations using the two models, the model incorporating greater flexibility in fish behavior exhibited weaker population-level responses to more extreme reductions in dry-season streamflow. We believe the application of individual-based models in this case has placed resource managers in a relatively strong position to forecast the consequences of future environmental alterations at the study site.

AB Infectious laryngotracheitis (ILT) is an economically important respiratory disease of poultry that affects the poultry industry worldwide. The disease is caused by gallid herpesvirus I (GaHV-1), a member of the genus Iltovirus, family Herpesviridae, subfamily Alphaherpesvirinae. The current incidence of the disease is heavily influenced by live attenuated vaccines, which have been used extensively since their introduction in the mid-twentieth century. The capability of current live attenuated vaccine viruses to revert to virulence and spread from bird to bird has shaped the molecular epidemiology of ILT. Because of the antigenic homogeneity among GaHV-1 strains, differentiation of strains has been achieved by targeting genomic differences between outbreak-related isolates and vaccine strains. Numerous genes and genomic regions have been utilized in the development of DNA-based diagnostic assays to differentiate outbreak-related isolates from vaccine strains in countries where ILT outbreaks have occurred. More recently, full genome sequences have allowed determination of the origin of some of the outbreak-related isolates circulating in some poultry production countries. Overall, molecular typing data collected worldwide have identified live attenuated vaccine-related isolates as the primary source for outbreaks of the disease.

TI Impacts of Migration on Household Production Choices: Evidence from

DT Article
AB The great migration from Chinese farms to cities during the past several decades ranks among the most economically consequential of modern population movements. We use a national sample of rice-producing Chinese households to examine the effects of that migration on agricultural production. Our assessment involves evaluating four alternative theories of labour market equilibrium in the framework of an expanded agricultural household model. Migration's farm production impacts appear to be slight, not on account of farm labour market perfections or remittance-financed technological improvements, but by substituting a reduction in leisure and other low-return activities for lost labour.

ID INTERNATIONAL-TRADE; LAND-USE; IMPACT; CMIP5
AB Agricultural production is sensitive to weather and thus directly affected by climate change. Plausible estimates of these climate change impacts require combined use of climate, crop, and economic models. Results from previous studies vary substantially due to differences in models, scenarios, and data. This paper is part of a collective effort to systematically integrate these three types of models. We focus on the economic component of the assessment, investigating how nine global economic models of agriculture represent endogenous responses to seven standardized climate change scenarios produced by two climate and five crop models. These responses include adjustments in yields, area, consumption, and international trade. We apply biophysical shocks derived from the Intergovernmental Panel on Climate Change's representative concentration pathway with end-of-century radiative forcing of 8.5 W/m(2). The mean biophysical yield effect with no incremental CO2 fertilization is a 17% reduction globally by 2050 relative to a scenario with unchanging climate. Endogenous economic responses reduce yield loss to 11%, increase area of major crops by 11%, and reduce consumption by 3%. Agricultural production, crop-land area, trade, and prices show the greatest degree of variability in response to climate change, and consumption the lowest. The sources of these differences include model structure and specification; in particular, model assumptions about ease of land use conversion, intensification, and trade. This study identifies where models disagree on the relative responses to climate shocks and highlights research activities needed to improve the representation of agricultural adaptation responses to climate change.

AB Low-carbon biofuel sources are being developed and evaluated in the United States and Europe to partially offset petroleum transport fuels. Current and potential biofuel production systems were evaluated from a long-term continuous no-tillage corn (Zea mays L.) and switchgrass (Panicum virgatum L.) field trial under differing harvest strategies and nitrogen (N) fertilizer intensities to determine overall environmental sustainability. Corn and switchgrass grown for bioenergy resulted in near-term net greenhouse gas (GHG) reductions of -29 to -396 grams of CO2 equivalent emissions per megajoule of ethanol per year as a result of direct soil carbon sequestration and from the adoption of integrated biofuel conversion pathways. Management practices in switchgrass and corn resulted in large variation in petroleum offset potential. Switchgrass, using best management practices produced 3919 +/- 117 liters of ethanol per hectare and had 74 +/- 2.2 gigajoules of petroleum offsets per hectare which was similar to intensified corn systems (grain and 50% residue harvest under optimal N rates). Co-locating and integrating cellulosic biorefineries with existing dry mill corn grain ethanol facilities improved net energy yields (GJ ha(-1)) of corn grain ethanol by >70%. A multi-feedstock, landscape approach coupled with an integrated biorefinery would be a viable option to meet growing renewable transportation fuel demands while improving the energy efficiency of first generation biofuels.

AB We report on the accuracy of using near-infrared spectroscopy (NIRS) to predict the age of Anopheles mosquitoes reared from wild larvae and a mixed age-wild adult population collected from pit traps after exposure to pyrethroids. The mosquitoes reared from wild larvae were estimated as <7 or >= 7 d old with an overall accuracy of 79%. The age categories of Anopheles mosquitoes that were not exposed to the insecticide papers were predicted with 78% accuracy whereas the age categories of resistant, susceptible and mosquitoes exposed to control papers were predicted with 82%, 78% and 79% accuracy, respectively. The ages of 85% of the wild-collected mixed-age Anopheles were predicted by NIRS as <= 8 d for both susceptible and resistant groups. The age structure of wild-collected mosquitoes was not significantly different for the pyrethroid-susceptible and pyrethroid-resistant mosquitoes (P = 0.210). Based on these findings, NIRS chronological age estimation technique for Anopheles mosquitoes may be independent of insecticide exposure and the environmental conditions to which the mosquitoes are exposed.

WILDLIFE; DYNAMICS; BIRTH
AB Branching processes have served as a model for chemical reactions, biological growth processes, and contagion (of disease, information, or fads). Through this connection, these seemingly different physical processes share some common universalities that can be elucidated by analyzing the underlying branching process. In this work we focus on coupled branching processes as a model of infectious diseases spreading from one population to another. An exceedingly important example of such coupled outbreaks are zoonotic infections that spill over from animal populations to humans. We derive several statistical quantities characterizing the first spillover event from animals to humans, including the probability of spillover, the first passage time distribution for human infection, and disease prevalence in the animal population at spillover. Large stochastic fluctuations in those quantities can make inference of the state of the system at the time of spillover difficult. Focusing on outbreaks in the human population, we then characterize the critical threshold for a large outbreak, the distribution of outbreak sizes, and associated scaling laws. These all show a strong dependence on the basic reproduction number in the animal population and indicate the existence of a novel multicritical point with altered scaling behavior. The coupling of animal and human infection dynamics has crucial implications, most importantly allowing for the possibility of large human outbreaks even when human-to-human transmission is subcritical.

AB The formerly monotypic genus Aesiocopa Zeller, 1877 is reviewed. Three species are included: A. vacivana Zeller, 1877 (type species) from Panama and Costa Rica; A. necrofolia Brown & Phillips, new species, from Mexico, Nicaragua, and Costa Rica; and A. grandis Brown, new species, from Costa Rica. The genus is recorded sparingly from Mexico to Panama. Although A. vacivana and A. grandis are known from only a handful of specimens, A. necrofolia has been reared from larvae numerous times in Costa Rica and from 15 different plant families: Asteraceae, Euphorbiaceae, Fabaceae, Hernandiaceae, Icacinaceae, Lauraceae, Magnoliaceae, Myrsinaceae, Myrtaceae, Piperaceae, Rubiaceae, Salicaceae, Sapindaceae, Smilacaceae, and Urticaceae. The abundance of rearing records suggests that the species is polyphagous, and the paucity of field-collected adults suggests that it may not be avidly attracted to light. The same may be true for its congeners.

AB The taxonomic status of Clepsis penetralis has remained enigmatic since its description in 1979. Using specimens collected or borrowed from across the U.S.A., we examined genitalic and wing characters as well as mitochondrial DNA sequence in order to distinguish C. penetralis from the similar congener C. peritana. The genomic integrity of the two species was strongly supported, and the mtDNA sequence data further suggest a potential additional new species from California. Examinations of collections across the country indicate that C. penetralis is a widespread species that has been widely overlooked.

TI Linking Bovine Tuberculosis on Cattle Farms to White-Tailed Deer and

AB Bovine tuberculosis is a bacterial disease caused by Mycobacterium bovis in livestock and wildlife with hosts that include Eurasian badgers (Meles meles), brushtail possum (Trichosurus vulpecula), and white-tailed deer (Odocoileus virginianus). Risk-assessment efforts in Michigan have been initiated on farms to minimize interactions of cattle with wildlife hosts but research on M. bovis on cattle farms has not investigated the spatial context of disease epidemiology. To incorporate spatially explicit data, initial likelihood of infection probabilities for cattle farms tested for M. bovis, prevalence of M. bovis in white-tailed deer, deer density, and environmental variables for each farm were modeled in a Bayesian hierarchical framework. We used geo-referenced locations of 762 cattle farms that have been tested for M. bovis, white-tailed deer prevalence, and several environmental variables that may lead to long-term survival and viability of M. bovis on farms and surrounding habitats (i.e., soil type, habitat type). Bayesian hierarchical analyses identified deer prevalence and proportion of sandy soil within our sampling grid as the most supported model. Analysis of cattle farms tested for M. bovis identified that for every 1% increase in sandy soil resulted in an increase in odds of infection by 4%. Our analysis revealed that the influence of prevalence of M. bovis in white-tailed deer was still a concern even after considerable efforts to prevent cattle interactions with white-tailed deer through on-farm mitigation and reduction in the deer population. Cattle farms test positive for M. bovis annually in our study area suggesting that the potential for an environmental source either on farms or in the surrounding landscape may contributing to new or re-infections with M. bovis. Our research provides an initial assessment of potential environmental factors that could be incorporated into additional modeling efforts as more knowledge of deer herd factors and cattle farm prevalence is documented.

AB Contamination of fresh produce could represent a public health concern because no terminal kill step is applied during harvest or at the processing facility to kill pathogens. In addition, once contaminated, pathogens may internalize into produce and be protected from disinfectants during the postharvest processing step. The objective of the current study was to determine the potential internalization of Escherichia coli O157:H7 into spinach roots and subsequent transfer to the edible parts. Because curli are involved in biofilm formation, we investigated whether their presence influence the internalization of E. coli O157:H7 into spinach. Further, the effect of the spinach cultivar on E. coli O157:H7 internalization was evaluated. Spinach plants were grown in contaminated soil as well as hydroponically to prevent mechanical wounding of the roots and inadvertent transfer of pathogens from the contamination source to the non-exposed plant surfaces. Results showed that E. coli O157:H7 could internalize into hydroponically grown intact spinach plants through the root system and move to the stem and leaf level. The incidence of internalization was significantly higher in hydroponically grown plants when roots were exposed to 7 log CFU/mL compared to those exposed to 5 log CFU/mL. The effect of cultivar on E. coli O157:H7 internalization was not significant (P > 0.05) for the analyzed spinach varieties, internalization incidences showing almost equal distribution between Space and Waitiki, 49.06% and 50.94% respectively. Wounding of the root system in hydroponically grown spinach increased the incidence of E. coli O157:H7 internalization and translocation to the edible portions of the plant. Experimental contamination of the plants grown in soil resulted in a greater number of internalization events then in those grown hydroponically, suggesting that E. coli O157:H7 internalization is dependent on root damage, which is more likely to occur when plants are grown in soil. Curli expression by E. coli O157:H7 had no significant effect on its root uptake by spinach plants. Published by Elsevier B.V.

AB Shiga toxin-producing Escherichia coli (STEC) strains belonging to serogroup O104 have been associated with sporadic cases of illness and have caused outbreaks associated with milk and sprouts. An outbreak that occurred in Europe in 2011 linked to fenugreek sprouts was caused by E. coli O104:H4 that had characteristics of an enteroaggregative E. coli (EAEC) but carried the gene that encoded for Shiga toxin 2. In this study, methods were developed for detection of this enteroaggregative STEC O104, as well as STEC O104 in sprouts. Multiplex PCR assays for enteroaggregative STEC O104:H4 targeted the stx(2), aggR, and wzx(104) genes, and for STEC O104 targeted the stx(1-2), ehxA, and wzx(104) genes. After incubating artificially contaminated sprouts at 4 degrees C for 48 h and overnight enrichment in modified buffered peptone water with pyruvate supplemented with three antibiotics (mBPWp), the pathogens were detected in all samples inoculated at a level of ca. 100 CFU/25 g. Several samples inoculated at lower concentrations of ca. 10 CFU/25 g were negative by the PCR assays, and this could have been due to cells not surviving or not being able to recover after the stress treatment at 4 degrees C for 48 h. For isolation of the pathogens, immunomagnetic separation (IMS) using magnetic beads coated with antibodies against O104 were employed, and this was followed by plating the beads onto mRBA and CHROMagar STEC O104 for isolation of E. coli O104:H4 and mRBA and CHROMagar STEC for isolation of E. coli O104:H7. Presumptive colonies were confirmed by agglutination using latex particles attached to antibodies against serogroup O104 and by the multiplex PCR assays. The methodologies described in this study for detection of enteroaggregative STEC O104:H4 and STEC O104 include the use of IMS and latex reagents for serogroup O104, and they enhance the ability to detect and isolate these pathogens from sprouts and potentially other foods, as well.

AB A common screen for plant antimicrobial compounds consists of separating plant extracts by paper or thin-layer chromatography (PC or TLC), exposing the chromatograms to microbial suspensions (e.g. fungi or bacteria in broth or agar), allowing time for the microbes to grow in a humid environment, and visualizing zones with no microbial growth. The effectiveness of this screening method, known as bioautography, depends on both the quality of the chromatographic separation and the care taken with microbial culture conditions. This paper describes standard protocols for TLC and contact bioautography with a novel application to amino acid-fermenting bacteria. The extract is separated on flexible (aluminum-backed) silica TLC plates, and bands are visualized under ultraviolet (UV) light. Zones are cut out and incubated face down onto agar inoculated with the test microorganism. Inhibitory bands are visualized by staining the agar plates with tetrazolium red. The method is applied to the separation of red clover (Trifolium pratense cv. Kenland) phenolic compounds and their screening for activity against Clostridium sticklandii, a hyper ammonia-producing bacterium (HAB) that is native to the bovine rumen. The TLC methods apply to many types of plant extracts and other bacterial species (aerobic or anaerobic), as well as fungi, can be used as test organisms if culture conditions are modified to fit the growth requirements of the species.

TI Generation of a Mixolab Profile After the Evaluation of the
Functionality of Different Commercial Wheat Flours for Hot-Press
Tortilla Production
SO CEREAL CHEMISTRY
LA English
DT Article
ID TEXTURAL PROPERTIES; STORAGE; QUALITIES
AB Refined wheat flours commercially produced by five different U.S. and Mexican wheat blends intended for tortilla production were tested for quality and then processed into tortillas through the hot-press forming procedure. Tortilla-making qualities of the flour samples were evaluated during dough handling, hot pressing, baking, and the first five days on the shelf at room temperature. The predominant variables that affected the flour tortilla performance were wet gluten content, alveograph W (220-303) and P/L (0.70-0.94) parameters, farinograph water absorption (57%) and stability (10.8-18.7 mm), starch damage (5.43-6.71%), and size distribution curves (uniform particle distribution). Flours produced from a blend of Dark Northern Spring (80%) and Mexican Rayon (20%) wheat had the highest water absorption, and tortillas obtained from this blend showed the highest diameter and lowest thickness. The whitest and best textured tortillas were obtained from the flour milled from three hard types of Mexican wheat blend. A Mixolab profile was generated from the best tortilla flours, those produced by mills 3 and 4. The Mixolab profile showed that a good flour for hot-press tortillas had a relatively lower absorption and short dough mix time compared with a bread flour and should have a significantly higher gluten compared with an all-purpose flour. Compared with bread flour, the tortilla flour had higher retrogradation and viscosity values. The Mixolab profile proved to be a good preliminary test to evaluate flours for hot-press tortillas.

TI Microenzymatic Evaluation of Oat (Avena sativa L.) beta-Glucan for
High-Throughput Phenotyping

AB Oats (Avena saliva L.) have received significant attention for their positive and consistent health benefits when consumed as a whole grain food, attributed in part to mixed-linkage (1-3,1-4)-beta-D-glucan (referred to as beta-glucan). Unfortunately, the standard enzymatic method of measurement for oat beta-glucan is costly and does not provide the high-throughput capability needed for plant breeding in which thousands of samples are measured over a short period of time. The objective of this research was to test a microenzymatic approach for high-throughput phenotyping of oat beta-glucan. Fifty North American elite lines were chosen to span the range of possible values encountered in elite oats. Pearson and Spearman correlations (r) ranged from 0.81 to 0.86 between the two methods. Although the microenzymatic method did contain bias compared with the results for the standard streamlined method, this bias did not substantially decrease its ability to determine beta-glucan content. In addition to a substantial decrease in cost, the microenzymatic approach took as little as 6% of the time compared with the streamlined method. Therefore, the microenzymatic method for beta-glucan evaluation is an alternative method that can enhance high-throughput phenotyping in oat breeding programs.

AB The most diverse wild tomato species Solanum peruvianum sensu lato (s.l.) has been reclassified into four separate species: Solanum peruvianum sensu stricto (s.s.), Solanum corneliomuelleri, Solanum huaylasense, and Solanum arcanum. However, reproductive barriers among the species are incomplete and this can lead to discrepancies regarding genetic identity of germplasm. We used genotyping by sequencing (GBS) of S. peruvianum s.l., Solanum neorickii, and Solanum chmielewskii to develop tens of thousands of mapped single nucleotide polymorphisms (SNPs) to analyze genetic relationships within and among species. The data set was condensed to 14 043 SNPs with no missing data across 46 sampled plants. Origins of accessions were mapped using geographical information systems (GIS). Isolation by distance, pairwise genetic distances, and number of clusters were estimated using population genetics approaches. Isolation by distance was strongly supported, especially between interspecific pairs. Eriopersicon (S. peruvianum s.s., S. corneliomuelleri, S. huaylasense) and Arcanum (S. arcanum, S. neorickii, S. chmielewskii) species groups were genetically distinct, except for S. huaylasense which showed 50% membership proportions in each group. Solanum peruvianum and S. corneliomuelleri were not significantly differentiated from each other. Many thousands of SNP markers were identified that could potentially be used to distinguish pairs of species, including S. peruvianum versus S. corneliomuelleri, if they are verified on larger numbers of samples. Diagnostic markers will be valuable for delimiting morphologically similar and interfertile species in germplasm management. Approximately 12% of the SNPs rejected a genome-wide test of selective neutrality based on differentiation among species of S. peruvianum s.l. These are candidates for more comprehensive studies of microevolutionary processes within this species complex.

TI Systematic review of the influence of foraging habitat on red-cockaded
woodpecker reproductive success

BEHAVIOR; QUALITY; GROWTH; LOUISIANA; ECOSYSTEM; MIDSTORY
AB Relationships between foraging habitat and reproductive success provide compelling evidence of the contribution of specific vegetative features to foraging habitat quality, a potentially limiting factor for many animal populations. For example, foraging habitat quality likely will gain importance in the recovery of the threatened red-cockaded woodpecker Picoides borealis (RCW) in the USA as immediate nesting constraints are mitigated. Several researchers have characterized resource selection by foraging RCWs, but emerging research linking reproductive success (e.g. clutch size, nestling and fledgling production, and group size) and foraging habitat features has yet to be synthesized. Therefore, we reviewed peer-refereed scientific literature and technical resources (e.g. books, symposia proceedings, and technical reports) that examined RCW foraging ecology, foraging habitat, or demography to evaluate evidence for effects of the key foraging habitat features described in the species' recovery plan on group reproductive success. Fitness-based habitat models suggest foraging habitat with low to intermediate pine Pinus spp. densities, presence of large and old pines, minimal midstory development, and herbaceous groundcover support more productive RCW groups. However, the relationships between some foraging habitat features and RCW reproductive success are not well supported by empirical data. In addition, few regression models account for >30% of variation in reproductive success, and unstandardized multiple and simple linear regression coefficient estimates typically range from -0.100 to 0.100, suggesting ancillary variables and perhaps indirect mechanisms influence reproductive success. These findings suggest additional research is needed to address uncertainty in relationships between foraging habitat features and RCW reproductive success and in the mechanisms underlying those relationships.

AB Adult civilian dependents of active duty military personnel (ADMP) may play a central role in influencing the home food environment and the risk of overweight and obesity in American Warfighters and military families. However, there is no information on whether this group would be receptive to weight control programs. We conducted a survey to determine the level of interest of adult civilian dependents of ADMP in participating in a group weight control program. Subjects were a convenience sample of 191 adult civilian dependents of ADMP (94% women, 6% men) based in Massachusetts and aged 33.8 +/- 8.4 years, body mass index 25.5 +/- 5.5 kg/m(2). Overall, there was a significant effect of body mass index on interest in program participation (p = 0.004). Eighty five percent of overweight participants and 100% of obese participants reported being Moderately Likely or Very Likely to participate in a provided weight control program. In overweight and obese survey respondents there was no significant effect of ADMP rank on interest in program participation (p = 0.34). These findings suggest that overweight and obese adult civilian dependents of ADMP may be very receptive targets for programs to control overweight and obesity in military families.

AB Studies using a ground-based system (NASA Space Radiation Laboratory) to examine the effects of exposure to high-energy charged particles or HZE particles on cognitive performance have interchangeably used whole-body exposures or exposures restricted to the head of the subject. For this study, we hypothesized that different types of exposure such as whole body vs. head only vs. body only might modulate the impact of irradiation on cognitive performance in different ways with the resulting cognitive performance outcomes being either independent of exposure type or strongly dependent on exposure type with each producing performance outcomes. To test these possibilities, three groups of rats were exposed to O-16 particles (1,000 MeV/n): (1) head only; (2) body only; (3) whole body. Cognitive performance was measured using the elevated plus-maze, novel object recognition, spatial location memory and operant responding on an ascending fixed-ratio schedule. The results indicated that the performance of the rats on the spatial location memory task was markedly different when they received head-only irradiation compared to whole-body exposure. For the operant responding task, irradiation of the whole body resulted in a more severe performance decrement than exposures restricted to the head. The results are discussed in terms of nontargeted effects of HZE particles and the findings suggest that studies that utilize different patterns of exposure may not be directly comparable and that astronauts may be at a greater risk for HZE particle-induced cognitive deficits than previously thought.

ID THORNLESS BLACKBERRY
AB Blackberries have now become a common fruit in marketing outlets, particularly in North America and the European Union. Blackberries have enjoyed expansion due to a combination of factors including improved cultivars, expanded marketing efforts and fruit availability, and an overall increase in berry consumption, especially as fresh fruit, in many areas of the world. It is estimated that cultivated blackberries are grown in excess of 25,000 ha worldwide. World production, and cultivation are commented. The rapid expansion of the blackberry industry has been remarkable. New, higher quality, cultivars, modified production practices and new production regions have all combined to make this crop one that consumers expect to be available fresh year-round in their grocery stores. As new cultivars are developed that combine the industry's need for high quality arrivals with increased flavors and expanded dates of harvest, the blackberry industry should expand further.

AB Premise of the study: Phenotypic acclimation of individual plants and genetic differentiation by natural selection within invasive populations are two potential mechanisms that may confer fitness advantages and allow plants to cope with environmental variation. The invasion of Spartina densiflora across a wide latitudinal gradient from California (USA) to British Columbia (Canada) provides a natural model system to study the potential mechanisms underlying the response of invasive populations to substantial variation in climate and other environmental variables.
Methods: We examined morphological and physiological leaf traits of Spartina densiflora plants in populations from invaded estuarine sites across broad latitudinal and climate gradients along the Pacific west coast of North America and in favorable conditions in a common garden experiment.
Key results: Our results show that key foliar traits varied widely among populations. Most foliar traits measured in the field were lower than would be expected under ideal growing conditions. Photosynthetic pigment concentrations at higher latitudes were lower than those observed at lower latitudes. Greater leaf rolling, reduced leaf lengths, and lower chlorophyll and higher carbon concentrations were observed with anoxic sediments. Lower chlorophyll to carotenoids ratios and reduced nitrogen concentrations were correlated with sediment salinity. Our results suggest that the variations of foliar traits recorded in the field are a plastic phenotypic response that was not sustained under common garden conditions.
Conclusions: Spartina densiflora shows wide differences in its foliar traits in response to environmental heterogeneity in salt marshes, which appears to be the result of phenotypic plasticity rather than genetic differentiation.

TI N, P, and K Supply to Pinot noir Grapevines: Impact on Berry Phenolics

AB Understanding the direct role that macronutrient supply (N, P, and K) has on berry chemistry was evaluated in Pinot noir grapevines grown in sand culture. Self-rooted Pinot noir vines were grown for three years with either full nutrition (Control) or three reduced levels of either N, P, or K supply while holding all other nutrients constant. Vines were managed to minimize differences in vine water status (altering irrigation to achieve similar daily soil moisture content) and fruit cluster solar exposure (altering leaf pulling to achieve similar cluster irradiance) due to varying nutrient supply so that indirect effects on berry chemistry could be largely eliminated. Berry chemistry was evaluated in the second and third years after different nutrient supply treatments were imposed. Results showed that low N, but not low P or K, altered berry free amino acid (FAA) and phenolic profiles. Low N supply reduced FAA and yeast assimilable nitrogen (YAN) in both years by up to 70% and altered certain FAAs more than others, thus changing berry FAA profile. The concentration of sugars, anthocyanins, and flavonol-glycosides increased in low N vines during the third season, but the increase in sugars and anthocyanins was attributed to the decline in berry size that year. Condensed tannins and total phenolic acids were increased in low N vines across both years, independent of changes in berry size. Results indicated that low N supply altered YAN to the greatest degree, while anthocyanin enhancement did not occur until yield and berry size were also reduced. Increased concentrations of tannins and phenolic acids in berries occurred in response to low N supply independent of reductions in yield and berry size.

AB While the greatest strength of systems biology may be to measure tens of thousands of variables across different genotypes, this simultaneously presents an enormous challenge to statistical analysis that cannot be completely solved with conventional approaches that identify and rank differences. Here we examine a diverse panel of conventional and transgenic, field-grown tomato fruits (Solanum lycopersicum L.) by liquid chromatography-mass spectrometry (LC-MS) metabolic fingerprinting. We used a progression of statistics to examine phenotypic variation observed. While clear trends were found by principal component analysis (PCA) related to genetic background and ripeness, it could not detect differences between transgenic genotypes and their nontransgenic parent variety. Partial least squares discriminant analysis (PLS-DA), a supervised method, identified 15 metabolic features of potential interest, but only five were significantly different between the transgenic lines and their nontransgenic parent. Weighted correlation network analysis (WGCNA) recognized relationships among these features and others, suggesting that a small suite of highly correlated compounds accumulated to significantly lower levels in the transgenic genotypes. We assert that metabolic fingerprinting with a series of statistical methods is an efficient and powerful approach to examine both large and small genetic effects on phenotypes of high value or interest.

AB The superior fiber properties of Gossypium barbadense L. serve as a source of novel variation for improving fiber quality in Upland cotton (G. hirsutum L.), but introgression from G. barbadense has been largely unsuccessful due to hybrid breakdown and a lack of genetic and genomic resources. In an effort to overcome these limitations, we constructed a linkage map and conducted a quantitative trait locus (QTL) analysis of 10 agronomic and fiber quality traits in a recombinant inbred mapping population derived from a cross between TM-1, an Upland cotton line, and NM24016, an elite G. hirsutum line with stabilized introgression from G. barbadense. The linkage map consisted of 429 simple-sequence repeat (SSR) and 412 genotyping-by-sequencing (GBS)-based single-nucleotide polymorphism (SNP) marker loci that covered half of the tetraploid cotton genome. Notably, the 841 marker loci were unevenly distributed among the 26 chromosomes of tetraploid cotton. The 10 traits evaluated on the TM-1 x NM24016 population in a multienvironment trial were highly heritable, and most of the fiber traits showed considerable transgressive variation. Through the QTL analysis, we identified a total of 28 QTLs associated with the 10 traits. Our study provides a novel resource that can be used by breeders and geneticists for the genetic improvement of agronomic and fiber quality traits in Upland cotton.

AB Wheat stem rust rapidly evolves new virulence to resistance genes. Recently emerged races in East Africa, such as TTKSK (or Ug99), possess broad virulence to durum cultivars, and only a limited number of genes provide resistance. An association mapping (AM) study conducted on 183 durum wheat accessions has allowed us to identify 41 quantitative trait loci (QTLs; determination coefficient [R-2] values from 1.1 to 23.1%) for seedling resistance to one or more of four highly virulent stem rust races: TRTTF, TTTTF, TTKSK (Ug99), and JRCQC, two of which (TRTTF and JRCQC) were isolated from Ethiopia. Among these loci, 24 are novel, while the remaining 17 overlapped with loci previously shown to provide field resistance in Ethiopia and/or chromosome regions known to harbor designated stem rust resistance designated loci (Sr). The identified loci were either effective against multiple races or race specific, particularly for race JRCQC. Our results highlight that stem rust resistance in durum wheat is governed in part by loci for resistance across multiple races, and in part by race-specific ones (23 and 18, respectively). Collectively, these results provide useful information to improve the effectiveness of marker-assisted selection towards the release of durum wheat cultivars with durable stem rust resistance.

AB Barley is a model plant in genomic studies of Triticeae species. However, barley's large genome size and high repetitive sequence content complicate the whole-genome sequencing. The majority of the barley genome is composed of transposable elements (TEs). In this study, TE repeat junctions (RJs) were used to develop a large-scale molecular marker platform, as a prerequisite to genome assembly. A total of 10.22 Gb of barley nonassembled 454 sequencing data were screened with RJPrimers pipeline. In total, 9,881,561 TE junctions were identified. From detected RJs, 400,538 polymerase chain reaction (PCR)-based RJ markers (RJMs) were designed across the genome, with an average of 39 markers/Mb. The utility of designed markers was tested using a random subset of RJMs. Over 94% of the markers successfully amplified amplicons, among which similar to 90% were genome specific. In addition to marker design, identified RJs were utilized to detect 1190,885 TEs across the genome. In gene-poor regions of the genome Gypsy elements comprised the majority of TEs (similar to 65%), while in gene-rich regions Gypsy, Copia, and Mariner were the main transposons, each representing an average similar to 23% of total TEs. The numerous RJ primer pairs developed in this study will be a valuable resource for barley genomic studies including genomic selection, fine mapping, and genome assembly. In addition, the results of this study show that characterizing RJs provides insight into TE composition of species without a sequenced genome but for which short-read sequence data is available.

AB Heterogeneity of infiltration and subsurface redistribution of soil water can have a profound influence on plant growth and productivity as well as water quality. However, substantial uncertainty exists in assessing hydrologic impacts over multiple scales confounded by multiple adjacent land uses. Spatial variabilities of soil surface hydraulic properties are key elements in understanding vadose zone hydrodynamics. The objective of this investigation was to evaluate the effects of land use, soil series, and microtopographic position on soil surface physiochemical and hydraulic properties (i.e., ponded and tension infiltration) during the transition from fall to winter seasons during a period of shallow aquifer recharge. Measurements were made across three Fragiudults (Captina, Nixa, and Johnsburg soil series) on a young alley-cropped agroforestry tract and an adjacent cattle-grazed pasture that constitute a headwater hillslope soil assemblage in the Ozark Highlands. Ponded and tension infiltration rates were affected (P < 0.05) by soils, microtopographic positions, and/or land uses. Tension infiltration rates, averaged across soils and land uses at a pressure head of -3 cm, were nearly twofold greater at the microtopographic low position (17.8 mm h(-1)) than the high (9.2 mm h(-1)) position, where the microtopographic high position in the landscape was generally a shallower soil than that at the microtopographic low position. However, when all infiltration measurements were evaluated together, no significant differences in infiltration dynamics were observed among soils, microtopographic positions, or land uses. Thus, a single infiltration pressure head function effectively characterized the hillslope soil assemblage evaluated in this study when shallow aquifer recharge was occurring. Greater bioporosity in upland grazed pastures may serve to naturally decrease hydraulic property variability across soils, which may simplify, rather than complicate, hydrologic partitioning between infiltration and runoff in grassland-based agroecosystems receiving frequent applications of animal manures in the Ozark Highlands.

ID PRECISION CONSERVATION; LOSSES
AB Corn (Zea mays L.) is important for food security in much of Ecuador. Small-scale farmers are using nitrogen (N) fertilizer without technical advice based on soil, crop, and climatologic data. The literature lacks studies where tools that can quickly assess management practices' effects on N uptake, N use efficiency, and risk of N losses to the environment in high-altitude mountain systems are validated. We tested corn response to fertilizer application and the capability of the Nitrogen Index to assess N dynamics within a conservation agriculture production system in a mountainous area of Ecuador. Responses to fertilizer were tested across six sites in the Bolivar province. Steep slopes and declining soil productivity make conservation agriculture a promising option in this area. However, N availability is limiting for corn production and better information is needed to optimize the system. Corn responded to fertilizer application with an average increase of 30 kg ha(-1) corn grain per every 1 kg of N ha(-1) applied (P < 0.001). The data suggest that N leaching increased with fertilizer application for areas with precipitation greater than 900 mm. The Nitrogen Index for Ecuador was able to quickly assess management practices' effects on N uptake (P < 0.001), N use efficiency (P < 0.001), and risk of N losses. It could be used to increase use of best management practices in these systems.

We evaluated the effects of crop species (spring wheat [Triticum aestivum L.], pea [Pisum sativum L.], and fallow), N fertilization rate (0.11 and 0.96 g N pot(-1)), and residue placement (no residue, surface placement, and incorporation into the soil) and rate (0, 20, and 40 g pot(-1)) on soil aggregation and C and N contents during a growing season under controlled soil and climatic conditions in the greenhouse. Soil samples collected from the field were grown with crops in the greenhouse and analyzed for aggregation and soil organic C, total N, particulate organic C, and particulate organic N contents in aggregates. Residue C and N losses, proportion of macroaggregates (> 0.25 mm), and soil C and N contents in microaggregates (< 0.25 mm) were higher in surface residue placement (20 g pot(-1)) under pea with 0.11 g N pot(-1) than the other treatments. The soil organic C and soil total N were greater in surface residue placement (40 g pot(-1)) under wheat with 0.96 g N pot(-1) in large and intermediate macroaggregates (8.00-4.75 and 4.75-2.00 mm, respectively), particulate organic N was greater in surface residue placement (20 g pot(-1)) under pea with 0.11 g N pot in large macroaggregates, but particulate organic C was greater in residue incorporation (20 g pot(-1)) under fallow with 0.96 g N pot(-1) in intermediate macroaggregate than the other treatments. Under controlled soil and environmental conditions, soil C and N levels in aggregates changed rapidly during a crop-growing season. Surface residue placement increased soil aggregation and C and N storage with concurrent losses of residue C and N, but residue incorporation increased coarse organic matter fraction. Results from this short-term experiment in the greenhouse agree with those obtained from the long-term study in the field.

AB Barley (Hordeum vulgare L.) Mildew resistance locus a (Mla) confers allele-specific interactions with natural variants of the ascomycete fungus Blumeria graminis f. sp. hordei (Bgh), the causal agent of powdery mildew disease. Significant reprogramming of Mla-mediated gene expression occurs upon infection by this obligate biotrophic pathogen.
We utilized a proteomics-based approach, combined with barley mla, required for Mla12 resistance 1(rar1), and restoration of Mla resistance1 (rom1) mutants, to identify components of Mla-directed signaling.
Loss-of-function mutations in Mla and Rar1 both resulted in the reduced accumulation of chloroplast copper/zinc superoxide dismutase 1 (HvSOD1), whereas loss of function in Rom1 re-established HvSOD1 levels. In addition, both Mla and Rom1 negatively regulated hvu-microRNA398 (hvu-miR398), and up-regulation of miR398 was coupled to reduced HvSOD1 expression. Barley stripe mosaic virus (BSMV)-mediated over-expression of both barley and Arabidopsis miR398 repressed accumulation of HvSOD1, and BSMV-induced gene silencing of HvSod1 impeded Mla-triggered H2O2 and hypersensitive reaction (HR) at barley-Bgh interaction sites.
These data indicate that Mla- and Rom1-regulated hvu-miR398 represses HvSOD1 accumulation, influencing effector-induced HR in response to the powdery mildew fungus.

AB We used natural and tracer nitrogen (N) isotopes in a Pinus taeda free air CO2 enrichment (FACE) experiment to investigate functioning of ectomycorrhizal and saprotrophic fungi in N cycling.
Fungal sporocarps were sampled in 2004 (natural abundance and N-15 tracer) and 2010 (tracer) and delta N-15 patterns were compared against litter and soil pools.
Ectomycorrhizal fungi with hydrophobic ectomycorrhizas (e. g. Cortinarius and Tricholoma) acquired N from the Oea horizon or deeper. Taxa with hydrophilic ectomycorrhizas acquired N from the Oi horizon (Russula and Lactarius) or deeper (Laccaria, Inocybe, and Amanita). N-15 enrichment patterns for Cortinarius and Amanita in 2010 did not correspond to any measured bulk pool, suggesting that a persistent pool of active organic N supplied these two taxa. Saprotrophic fungi could be separated into those colonizing pine cones (Baeospora), wood, litter (Oi), and soil (Ramariopsis), with delta(1)5N of taxa reflecting substrate differences. N-15 enrichment between sources and sporocarps varied across taxa and contributed to delta N-15 patterns.
Natural abundance and N-15 tracers proved useful for tracking N from different depths into fungal taxa, generally corresponded to literature estimates of fungal activity within soil profiles, and provided new insights into interpreting natural abundance delta N-15 patterns.

ID ZAPRIONUS-INDIANUS; SUZUKII; IDENTIFICATION
AB The African fig fly, Zaprionus indianus Gupta (Diptera: Drosophilidae), is an invasive fruit pest that has spread rapidly through much of the eastern United States. Tests were conducted in southern Florida that recorded the response of Z. indianus to baits that included Merlot wine, rice vinegar, ethanol and acetic acid, alone and in combination. The flies were attracted to the wine but not to the vinegar or unbaited traps and were most strongly attracted to the combination of wine and vinegar. More flies were captured in traps baited with the combination of ethanol and acetic acid, the most abundant volatiles of wine and vinegar respectively, than in traps baited with either chemical alone or in unbaited traps. A subsequent test found that traps baited with wine plus acetic acid were as attractive as traps baited with wine plus vinegar. In this test, there was no difference in capture in unbaited traps or traps baited with ethanol plus acetic acid, and intermediate capture was obtained in traps baited with vinegar plus ethanol. These findings suggest that it may be possible to develop a synthetic chemical lure for Z. indianus that is based on volatiles from wine used in combination with acetic acid alone or in combination with other volatiles from vinegar.

AB Tropical soda apple (Solanum viarum Dunal) (Solanaceae) is a small shrub native to South America that is invasive in pastures and conservation areas across Florida. Dense patches of tropical soda apple not only reduce cattle stocking rates and limit their movement, but also serve as reservoirs for pests of solanaceous crops. A classical biological control program was initiated in 1994 with exploration for natural enemies of tropical soda apple in Argentina, Brazil, and Paraguay. Host specificity tests conducted under laboratory and field conditions demonstrated that the leaf feeding beetle Gratiana boliviana Dunal (Coleoptera: Chrysomelidae) was a specialist herbivore that completes development only on the target weed. After obtaining appropriate permits, field releases of G. boliviana were initiated in Florida in May of 2003. Larvae and adults of G. boliviana feed on tropical soda apple leaves and may completely defoliate their host plants, resulting in reduced growth and fruit production. Mass rearing facilities for the beetle were established in northern, central and southern Florida, and adults were either hand-carried or transported to release sites by overnight courier. From 2003 to 2011, a total of 250,723 beetles were released and they became established throughout Florida, however, their impact is more noticeable in regions below latitude 29 degrees N. Reductions of tropical soda apple densities caused by damage by the beetle were visible 2-3 yr after initial release, or in some cases, within a few months. Various methods of technology transfer were used to inform the public, land owners, funding agencies and scientists about the biological control program, including articles in trade magazines, extension publications, websites, videos, field days and scientific publications. The project was successful because of the coordinated efforts of personnel from federal, state and county agencies.

AB The redbay ambrosia beetle, Xyleborus glabratus Eichhoff, vectors laurel wilt, Raffaelea lauricola T. C. Harr., Fraedrich & Aghayeva, that quickly kills all large diam (> 2.5cm) redbay trees [Persea borbonia (L.) Sprengel] in an area but smaller diam trees (< 2.5cm) survive for years. We measured densities of X. glabratus attacks on hanging bolts of freshly cut mature redbay annually for 5 yr (2007-2011) at 7 locations varying in age of infestation from newly infested in 2007 to those that were among the oldest infested areas (infested in 2002 or earlier), to determine if populations persist after mature host trees are gone. Attack densities on redbay bolts at the field sites varied from 10-25 X. glabratus attacks/100 cm(2) where large dying redbay trees were still present, to < 1 attack/100cm(2) at sites where few or no trees > 2.5 cm diam near ground level were still living at the beginning of the study in 2007. Despite having no large trees available, populations of the beetle persisted at 2 of the 3 oldest infested sites throughout the 5-year survey period (2007-2011). In 2012 we studied X. glabratus utilization of small diam redbay wood as a possible explanation of how populations might survive in these areas in the absence of larger trees. In laboratory trials, X. glabratus produced 27.8 +/- 6.63 adults/gallery (+/- SE) from 18 galleries constructed in portions of redbay trees that averaged 3.2 +/- 0.02 cm diam at the point of attack. The smallest stem section to support a successful gallery was 1.7 cm diam but it produced only 2 adults. In field trials no attacks occurred in portions of stems < 1.6 cm diam. Upon stem dissection, more brood was found in stem sections near the ground (0-10 cm) than in those over 80 cm above ground. In addition, brood abundance in10 cm long tree sections exhibited a positive non-linear relationship (cubic polynomial; R-2 = 0.21) with section diam. Our data suggest that X. glabratus can maintain low populations in areas devoid of large redbay by utilizing 2-3 cm diam portions of small trees primarily near ground level.

AB Male Phyllocnistis citrella Stainton (Lepidoptera: Gracillariidae) were captured in pheromone-baited traps in pastureland 1.2 km west of an infested citrus grove. Capture of males was correlated with northeast wind blowing from the groves, which suggests males were transported passively on wind currents from groves before orienting to pheromone traps. Female P. citrella located and oviposited on 75% of sentinel citrus plants placed 1.2 km west of the groves by 6 weeks. Movement of this species as far as 1.2 km suggests that groves treated with pheromone components for mating disruption will be vulnerable to damage caused by mated females arriving from neighboring groves within 1.2 km. Treated groves may be particularly susceptible to influx of moths carried on wind.

AB Tamarixia radiata is regarded as one of the Asian citrus psyllid's most important natural enemies, and is thus currently being mass-reared and released by a number of laboratories in North America. It may not always be possible to immediately release newly-emerged adults, in which case it would be advantageous to store the parasitoids under optimal conditions until release. We found that newly-emerged adult T. radiata can be stored at 20 to 30 degrees C (14 h light photo phase) in vials containing honey with greater than 95% survival for up to 14 days. However, parasitoids stored for 14 days with honey at 25 degrees C parasitized fewer psyllid nymphs than newly emerged parasitoids. Thus, adult parasitoids can be stored, but they should be released as soon as possible for maximal parasitism.

AB A field test was conducted using Lindgren traps baited with (1) ethanol, (2) ethanol plus conophthorin, and (3) ethanol, conophthorin, and green LEDs (525 nm) to compare their efficacy for capture of bark and ambrosia beetles. Captures of Cnestus mutilatus were similar with all 3 treatments. Captures of Xylosandrus crassiusculus and other Scolytinae were significantly higher with ethanol-baited traps supplemented with conophthorin and green LEDs, as compared to traps baited with ethanol alone. Results of this study indicate that detection and monitoring of pest Scolytinae may be improved by incorporating conophthorin and green LEDs into the standard ethanol-baited Lindgren trap.

AB In phylogenetic analyses of the genus Streptomyces using 16S rRNA gene sequences, Streptomyces albus subsp. albus NRRL B-1811(T) forms a cluster with five other species having identical or nearly identical 16S rRNA gene sequences. Moreover, the morphological and physiological characteristics of these other species, including Streptomyces almquistii NRRL B-1685(T), Streptomyces flocculus NRRL B-2465(T), Streptomyces gibsonii NRRL B-1335(T) and Streptomyces rangoonensis NRRL B-12378(T) are quite similar. This cluster is of particular taxonomic interest because Streptomyces albus is the type species of the genus Streptomyces. The related strains were subjected to multilocus sequence analysis (MLSA) utilizing partial sequences of the housekeeping genes atpD, gyrB, recA, rpoB and trpB and confirmation of previously reported phenotypic characteristics. The five strains formed a coherent cluster supported by a 100% bootstrap value in phylogenetic trees generated from sequence alignments prepared by concatenating the sequences of the housekeeping genes, and identical tree topology was observed using various different tree-making algorithms. Moreover, all but one strain, S. flocculus NRRL B-2465(T), exhibited identical sequences for all of the five housekeeping gene loci sequenced, but NRRL B-2465(T) still exhibited an MLSA evolutionary distance of 0.005 from the other strains, a value that is lower than the 0.007 MLSA evolutionary distance threshold proposed for species-level relatedness. These data support a proposal to reclassify S. almquistii, S. flocculus, S. gibsonii and S. rangoonensis as later heterotypic synonyms of S. albus with NRRL B-1811(T) as the type strain. The MLSA sequence database also demonstrated utility for quickly and conclusively confirming that numerous strains within the ARS Culture Collection had been previously misidentified as subspecies of S. albus and that Streptomyces albus subsp. pathocidicus should be redescribed as a novel species, Streptomyces pathocidini sp. nov., with the type strain NRRL B-24287(T).

AB Dimocarpus longan is a subtropical fruit crop whose year-round production relies on the application of KClO3 to induce flowering; however, the mechanism by which this chemical causes flowering is yet unknown. To further characterize floral signaling in this species, we have isolated three longan FLOWERING LOCUS T (FT)-like genes and studied their activities by heterologous expression in Arabidopsis. Expression of two of these genes (DlFT2 and DlFT3) accelerates flowering, whereas expression of the third gene (DlFT1) causes delayed flowering and produced floral morphology defects. This anti-florigenic protein may be a member of a class of FT-like family involved in flowering time control in biennial and perennial species. Surprisingly, KClO3 treatment also suppressed the expression of both DlFT2 and DlFT3 in a field trial.

AB BACKGROUND: Preserving the genetic diversity of Central Asia includes conserving wild "apricots found in the foothills of several mountain ranges. These include primitive and genetically diverse populations with important characteristics for crop improvement. Apricot seeds have a short storage life, so cryopreservation of the seeds of wild populations is important for conserving the genetic diversity. OBJECTIVE: This study was to determine a suitable protocol for long-term storage. METHODS: This study tested a range of protocols using embryos and embryonic axes for storage of an important population of wild apricots and to determine if seed size and the distribution of moisture in the seed play a role in successful cryopreservation. RESULTS: Germination of scarified whole seed from trees in the 'Jungar' population of Prunus armeniaca varied from 63% to 90% after 1 h in liquid nitrogen (LN) and was generally better at 7% moisture content (MC) than at the original 14% MC. Embryos (4% MC) from stratified seed had only 33% germination after LN exposure. Isolated embryonic axes from non-stratified seed germinated at 86% to 100% following drying to 4% or 7% MC. Examination of three seed sizes determined that the MC of whole seed, embryos and isolated axes varied with the seed size and shape. MC of whole seeds and embryos decreased as size decreased, however, the axis MC did not. MC of medium-size seed was more evenly distributed between the axis and endosperm than in the larger or smaller samples. Cryopreservation of axes from medium-sized seed was good at any moisture content and a 1-h drying time was significantly better than 90 min. for axes of all seed sizes. Cryopreservation of axes using vitrification protocols initially designed for shoot tips produced germination similar to or lower than seed and axis drying techniques. CONCLUSION: We recommend storing apricot germplasm as unstratified seed dried to 7% MC or as isolated embryonic axes.

AB The inner perivitelline layer (IPL) sperm hole assay provides an objective assessment of the number of sperm penetrating the hen's ovum at the germinal disc. That number will provide insight into numerous parameters concerning fertility, including, but not limited to, the probability of the ovum being fertilized (true fertility), the duration of fertility, an assessment of mating activity, the effect of inseminating in vitro-stored semen, and the influence of spiking a breeder flock. In the current paper, we discuss the use of a filter paper ring to isolate and process the IPL overlying the germinal disc (PL disc) in 5 species of domestic birds. The morphology of the PL disc is also described to assist those using the sperm hole assay during sperm hole counting. The filter ring approach was successfully used with chicken, turkey, duck, goose, and Japanese quail eggs; the PL discs remained intact and stretched across the filter ring and sperm holes, when present, were clearly discernible. Morphologically, the PL disc appeared to be a silhouette of the germinal disc, including the germinal vesicle observed in follicular oocytes. The fibers forming the IPL had a honeycomb-like arrangement that could be mistaken for actual sperm holes in faintly stained slides. Given its diversity of applications and relative simplicity using the filter ring, it is recommended that the sperm hole assay be part of a quality control program at the hatchery. Already used in the scientific community, this filter ring method has the additional advantage that the blastoderm may be collected before the staining process.

AB The pigment glands of the cotton plant (Gossypium) produce a group of structurally related terpenoid aldehydes that protect the plant from herbivorous insects. Of these terpenoids, the most extensively studied is gossypol. Gossypolone, a compound closely related to gossypol, has been reported in the pigment glands but its activity against bollworm, Helicoverpa zea (Boddie), has not been reported. We report the effect on bollworm fed gossypol and gossypolone at concentrations of 0.06, 0.08, and 0.12% in an artificial diet. In previous studies, gossypol showed a hormetic effect when fed to tobacco budwornn, Heliothis virescens (Fabricius), or Helicoverpa armigera (Hubner); in the present study gossypol also showed a hormetic effect when fed to bollworm. Gossypolone did not exhibit a hormetic effect at the concentrations tested, but pupae from larvae fed 0.12% gossypolone were significantly smaller than those fed the check diet or any of the diets with gossypol. Gossypol at the concentrations tested did not delay days to pupation, but in an earlier study gossypol at 0.16% delayed days to pupation from 13.9 +/- 0.5 to 22.6 +/- 1.0. In this study, gossypolone also delayed days to pupation but at a lower concentration [i.e., gossypolone at 0.12% delayed days to pupation from 13.3 +/- 0.1 for the check to 20.8 +/- 0.7 days]. A delay in days to pupation will reduce the number of generations that develop during a growing season, and may reduce larval survival. The biosynthesis of gossypolone may be due to a single gene. If so, increased expression of the gene could provide an overall increase in resistance to Heliothines pests of cotton.

TI Aphids and Parasitoids in Wheat and Nearby Canola Fields in Central
Oklahoma
SO SOUTHWESTERN ENTOMOLOGIST
LA English
DT Article
AB In central Oklahoma, winter canola (Brassica napus L.) has recently become the primary rotational winter crop with wheat (Triticum aestivum L.). Annual aphid pest outbreaks in canola have resulted in widespread application of insecticide. Insect parasitoids, which frequently suppress aphids in nearby wheat, may move to canola because of large numbers of aphids. These parasitoids probably will be exposed to insecticide. Lysiphlebus testaceipes Cresson is the dominant parasitoid of aphid pests in wheat in Oklahoma and can frequently suppress and maintain aphid infestations below the economic injury level. The expansion of canola acreage in Oklahoma might disrupt biological control of cereal aphids in wheat if L. testaceipes prefers to colonize canola because of the abundance of aphids and many die as a result of more frequent use of insecticide in canola. In this case, canola could act as an ecological trap for L. testaceipes. We surveyed aphids and their parasitoids in wheat and nearby canola fields in central Oklahoma approximately at flowering time for canola. The purpose was to determine the relative abundance of aphids and parasitoids in each crop and assess the potential for canola fields to act as an ecological trap for L. testaceipes. For aphids collected from canola fields, Diaeretiella rapae (M'Intosh) was the dominant parasitoid, with rates of parasitism ranging from 2 to 27%. Aphelinus sp. also parasitized the cabbage aphid, Brevicotyne brassicae L., but was rare. Lysiphlebus testaceipes was not recovered from any species of aphid in canola despite being abundant on aphids in nearby wheat fields, with parasitism ranging from 3 to 43%. The results suggested limited potential for canola to attract and potentially serve as an ecological trap for L. testaceipes from wheat.

AB Twospotted spider mite, Tetranychus urticae Koch, feeds on epidermal cells of foliage, destroys photosynthetic cells, and reduces yield, fiber quality, and seed germination of cotton, Gossypium hirsutum L. With a short life cycle, prolific fecundity, an arrhenotokous reproduction, and an ability to expeditiously digest and detoxify xenobiotics, twospotted spider mite has the propensity to develop resistance to insecticides. Despite mobility, small size, and difficulties associated with handling of twospotted spider mites, this study demonstrated that the 20-ml glass-vial bioassay is a useful technique to evaluate contact toxicity of acaricides against adult mites in a laboratory. A colony of twospotted spider mites was maintained on pinto beans, Phaseolus vulgaris L. in a greenhouse. Abamectin with LC50 (95% CL) of 0.014 (0.01-0.02) mu g per vial was 1,006 time more toxic than spiromesifen with a LC50 of 14.086 (7.592-42.371) mu g per vial. The LC50 values of spiromesifen and propargite were comparable. Bifenazate was 10 times more toxic than dicofol to twospotted spider mite. The order of toxicity of acaricides tested against twospotted spider mite adults was abamectin > bifenazate > dicofol > propargite = spiromesifen. These data are useful for developing baseline contact toxicity for adult twospotted spider mite and monitoring tolerance to acaricides used on cotton in Central Texas.

AB A restriction digestion method has been developed for haplotyping the potato psyllid, Bactericera cockerelli Sulc., an economically important pest of solanaceous crops. This method differentiates the four known potato psyllid haplotypes by using restriction enzyme digestion of a portion of the mitochondrial large subunit ribosomal RNA, tRNA-Val, and a portion of the small subunit ribosomal RNA, providing a second target within the mitochondrial DNA for haplotyping studies. This technique also provides a good alternative to the current method of potato psyllid haplotyping which uses high-resolution melting analysis, a technique that requires access to a real-time PCR machine with high-resolution melting capabilities. Potato psyllid haplotyping by restriction digestion is done using basic laboratory equipment that is readily available for smaller laboratories with budgetary limitations, thereby providing an excellent tool for laboratories of all sizes to identify psyllid populations.

AB Potato psyllid, Bactericera cockerelli, vectors the bacterium associated with the devastating zebra chip disease of potato, Solanum tuberosum L., in the United States, Mexico, Central America, and New Zealand. A seasonal pattern of appearance of the psyllid in crops from southern to northern regions of the United States is well documented. Potatoes are commonly grown as winter and summer crops in southern and northern parts, respectively, of the United States. No other plant material is available for psyllids when each crop is planted, and the psyllids must migrate into each crop each season. Appearance of psyllids in potato crops commonly starts at an initial focus, often at field margins or other breaks in the canopy, such as irrigation tracks. Psyllids readily jump and fly when disturbed, providing an obvious mechanism for dispersal within a crop. Good experimental evidence also supports longer distance dispersal of potato psyllid, from tens of meters to a few kilometers, most likely by cumulative short distances between suitable host plants within a region. Seasonal infestation observations suggest annual continental-wide migration of the psyllid, although little direct experimental evidence yet exists. Mechanisms for dispersal of potato psyllid over continental distances have been proposed, largely associated with seasonal wind patterns. However, recent overwintering observations in the northern regions of its native zone in the United States and identification of geographically-defined and genetically distinct potato psyllid populations, suggest a static regional status of at least some populations. Thus, a review of migration of potato psyllid into crops is presented herein, and a. new paradigm for considering overwintering strategies of potato psyllid is required.

ID ROLLER-CRIMPER
AB Roller/crimper implements have been used in large conservation farming systems to terminate cover crops near maturity and flatten them down to create a mulch through which cash crops can be planted directly into the cover residue. On small farms, tractors are usually small and less powerful relative to large farms. Daily field operations are often limited by tractor size. In vegetable organic production systems, field operations are often done one bed at a time. Typical rollers/crimpers can be too heavy for the available tractors and too large for the narrow beds that are common in these smaller vegetable systems. To address needs associated with conservation practices on small farms, a new roller/crimper powered by a tractor's. PTO was developed for self-propelled, walk-behind tractors to allow small farms to successfully lay-down and terminate cover crops. This patented powered roller/crimper was tested in 2010, 2011, and 2012 to determine effectiveness of terminating a rye cover crop (Secale cereale L). In 2010, two weeks after rolling, the average rye termination rate was 87.5% compared to 40.8% for non-rolled rye. In 2011 and 2012, two weeks after application of rolling treatments, rye termination rates exceeded 97% (99.9% in 2011 and 97.5% in 2012) which were high enough to plant cash crops into desiccated rye residue. Three weeks after rolling, termination rates averaged over rolling treatments in each growing season were 98.9%, 100.0%, and 99.9%, for 2010, 2011, and 2012, respectively. Results showed that the powered roller/crimper successfully terminated rye and generated termination rates that were similar or higher compared to larger rollers. In 2010, there was evidence of significant soil moisture conservation, when one week after rolling rye, soil volumetric moisture content (VMC) for rolled/crimped rye residue ranged from 7.9% to 8.9% versus soil moisture for non-rolled control (standing rye) having a VMC of 5.0%. Similarly in 2012, one week after rolling, soil moisture under rolled rye reside was higher, from 10.6% to 11.3% VMC versus non-rolled rye (7.3%). Overall, the powered roller/crimper performed as well as larger and heavier rollers/crimpers and this concept can be applicable on small farms where limited power walk-behind tractors are used

AB Wetland Reservoir Subirrigation Systems (WRSIS) are innovative agricultural water recycling systems that can provide economic and environmental benefits. A constructed wetland is a main component of WRSIS, and one important function of this constructed wetland is drainage water treatment of nitrogen. Four field tests were therefore conducted at a northwest Ohio WRSIS wetland to evaluate nitrate-nitrogen (NO3--N), ammonium-nitrogen (NH4+-N), and total nitrogen (TN) removal effectiveness. Tests I and 2 had lower inflow water volumes, shorter effective retention times, and smaller nitrogen fertilizer input loads. Test 3 had an intermediate inflow volume, intermediate effective retention time, and an intermediate nitrogen input load, while Test 4 had a high inflow volume, long effective retention time, and a large nitrogen input load. Based on nitrogen mass balance calculations, wetland processes reduced NO3--N, NH4+-N, and TN by 11.0%, 61.7%, and 13.2%, respectively, during Test I, 10.8%, 41.7%, and 11.7%, respectively, during Test 2, 44.0%, 87.5%, and 44.9%, respectively, during Test 3, and 15.6%, 81.1%, and 16.1%, respectively, during Test 4. Tests I, 2, and 3 were run consecutively, and if considered as a single test having three water inflow periods, three water outflow periods, and three nitrogen fertilizer inputs, then the NO3--N, NH4+ -N, and TN reductions for Test 1 -> 2 -> 3 were 36.8%, 78.1%, and 38.1%, respectively. Test 1 -> 2 -> 3 and Test 4 combined had NO3--N, NH4+-N, and TN reductions of 27.7%, 79.2%, and 28.5%, respectively. For the three tests conducted in May and June, 2009, Test 3 had the longest effective retention time, which may account for the better nitrogen reduction results achieved with Test 3 as compared to Tests I and 2. Cooler temperatures for Test 4 during October and November 2009 may have decreased denitrifying bacterial activity, in turn suppressing the amount of NO3--N and TN reduction obtained with Test 4. Overall results of this study indicate that WRSIS wetlands are capable of providing water quality benefits by removing substantial amounts of nitrogen present in drainage waters.

AB Eucalyptus plantations are normally found in vulnerable ecosystems such as steep slope, soil with low natural fertility and lands that were degraded by agriculture. The objective of this study was to obtain Universal Soil Loss Equation (USLE) factors and use them to estimate water erosion risk in regions with eucalyptus planted. The USLE factors were obtained in field plots under natural rainfall in the Rio Doce Basin, MG, Brazil, and the model applied to assess erosion risk using USLE in a Geographic Information System. The study area showed rainfall-runoff erosivity values from 10,721 to 10,642 MJ mm ha(-1) h(-1) yr(-1). Some soils (Latosols) had very low erodibility values (2.0 x 10(-4) and 1.0 x 10(-4)t h MJ(-1) mm(-1)), the topographic factor ranged from 0.03 to 10.57 and crop and management factor values obtained for native forest, eucalyptus and planted pasture were 0.09, 0.12 and 0.22, respectively. Water erosion risk estimates for current land use indicated that the areas where should receive more attention were mainly areas with greater topographic factors and those with Cambisols. Planning of forestry activities in this region should consider implementation of other conservation practices beyond those already used, reducing areas with a greater risk of soil erosion and increasing areas with very low risk.

AB Phytoplasmal diseases occur wherever peach (Prunus persica) trees are grown. However, the causal agents differ considerably in taxonomy, insect vector relationships and geographic locations. X-disease of peach is widespread in North America, but does not occur elsewhere in the world. X-disease is induced by 'Candidatus Phytoplasma pruni', a member of the X-disease phytoplasma group (16SrIII group, subgroup 16SrIII-A). Peach rosette, peach red suture, and peach yellows, which occur in eastern United States and Canada are all caused by the X-disease phytoplasma. Another North America disease, peach yellow leaf roll (PYLR) is present in a limited area of northern California. Its causal agent is classified in the apple proliferation (AP) group, 16SrX group, as a subtype of the pear decline phytoplasma. In Europe, phytoplasmal diseases of peach are reported under the name European stone fruit yellows and incited by 'Ca. P. prunorum', a member of the AP group, subgroup 16SrX-B. 'Ca. P. prunorum' is closely related to the PYLR agent. In Lebanon and Iran, peach trees are affected by almond witches' broom, a lethal disease incited by 'Ca. P. phoenicium', a member of the 16SrIX group, subgroup 16SrIX-B. Phytoplasmas of other phylogenetic groups, known to infect a wide range of plant hosts, have been identified in declining peach trees in several fruit-growing areas of the world. The pathological relevance of several 'non-peach' phytoplasmas requires further investigations as their presence was ascertained by nested PCR assays only.

AB The domestication and development of cattle has considerably impacted human societies, but the histories of cattle breeds and populations have been poorly understood especially for African, Asian, and American breeds. Using genotypes from 43,043 autosomal single nucleotide polymorphism markers scored in 1,543 animals, we evaluate the population structure of 134 domesticated bovid breeds. Regardless of the analytical method or sample subset, the three major groups of Asian indicine, Eurasian taurine, and African taurine were consistently observed. Patterns of geographic dispersal resulting from co-migration with humans and exportation are recognizable in phylogenetic networks. All analytical methods reveal patterns of hybridization which occurred after divergence. Using 19 breeds, we map the cline of indicine introgression into Africa. We infer that African taurine possess a large portion of wild African auroch ancestry, causing their divergence from Eurasian taurine. We detect exportation patterns in Asia and identify a cline of Eurasian taurine/indicine hybridization in Asia. We also identify the influence of species other than Bos taurus taurus and B. t. indicus in the formation of Asian breeds. We detect the pronounced influence of Shorthorn cattle in the formation of European breeds. Iberian and Italian cattle possess introgression from African taurine. American Criollo cattle originate from Iberia, and not directly from Africa with African ancestry inherited via Iberian ancestors. Indicine introgression into American cattle occurred in the Americas, and not Europe. We argue that cattle migration, movement and trading followed by admixture have been important forces in shaping modern bovine genomic variation.

AB Circulating homocysteine levels (tHcy), a product of the folate one carbon metabolism pathway (FOCM) through the demethylation of methionine, are heritable and are associated with an increased risk of common diseases such as stroke, cardiovascular disease (CVD), cancer and dementia. The FOCM is the sole source of de novo methyl group synthesis, impacting many biological and epigenetic pathways. However, the genetic determinants of elevated tHcy (hyperhomocysteinemia), dysregulation of methionine metabolism and the underlying biological processes remain unclear. We conducted independent genome-wide association studies and a meta-analysis of methionine metabolism, characterized by post-methionine load test tHcy, in 2,710 participants from the Framingham Heart Study (FHS) and 2,100 participants from the Vitamin Intervention for Stroke Prevention (VISP) clinical trial, and then examined the association of the identified loci with incident stroke in FHS. Five genes in the FOCM pathway (GNMT [p = 1.60 x 10(-63)], CBS [p = 3.15 x 10(-26)], CPS1 [p = 9.10 x 10(-13)], ALDH1L1 [p = 7.3 x 10(-13)] and PSPH [p = 1.17 x 10(-16)]) were strongly associated with the difference between pre- and post-methionine load test tHcy levels (Delta POST). Of these, one variant in the ALDH1L1 locus, rs2364368, was associated with incident ischemic stroke. Promoter analyses reveal genetic and epigenetic differences that may explain a direct effect on GNMT transcription and a downstream affect on methionine metabolism. Additionally, a genetic-score consisting of the five significant loci explains 13% of the variance of DPOST in FHS and 6% of the variance in VISP. Association between variants in FOCM genes with Delta POST suggest novel mechanisms that lead to differences in methionine metabolism, and possibly the epigenome, impacting disease risk. These data emphasize the importance of a concerted effort to understand regulators of one carbon metabolism as potential therapeutic targets.

DE veterinary laboratory; capacity building; Southeast Asia; EID
preparedness; H5N1; HPAI
AB The outbreak of highly pathogenic H5N1 avian influenza, with its international spread, confirmed that emerging infectious disease control must be underpinned by effective laboratory services. Laboratory results are the essential data underpinning effective surveillance, case diagnosis, or monitoring of responses. Importantly, laboratories are best managed within national and international networks of technological support rather than in isolation. A well planned laboratory network can deliver both a geographical spread of testing capacity and also a cost effective hierarchy of capability. Hence in the international context regional networks can be particularly effective. Laboratories are an integral part of a country's veterinary services and their role and function should be clearly defined in the national animal health strategy and supporting government policies. Not every laboratory should be expected to deliver every possible service, and integration into regional and broader international networks should be a part of the overall strategy. The outputs required of each laboratory should be defined and then ensured through accredited quality assurance. The political and scientific environment in which laboratories operate changes continuously, not only through evolving national and regional animal health priorities but also through new test technologies and enhancements to existing technologies. Active networks help individual laboratories to monitor, evaluate, and respond to such challenges and opportunities. The end result is enhanced emerging infectious disease preparedness across the region.

AB Thirty-two epizootics of high pathogenicity avian influenza (HPAI) have been reported in poultry and other birds since 1959. The ongoing H5N1 HPAI epizootic that began in 1996 has also spilled over to infect wild birds. Traditional stamping-out programs in poultry have resulted in eradication of most HPAI epizootics. However, vaccination of poultry was added as a control tool in 1995 and has been used during five epizootics. Over 113 billion doses of AI vaccine have been used in poultry from 2002 to 2010 as oil-emulsified, inactivated whole AIV vaccines (95.5%) and live vectored vaccines (4.5%). Over 99% of the vaccine has been used in the four H5N1 HPAI enzootic countries: China including Hong Kong (91%), Egypt (4.7%), Indonesia (2.3%), and Vietnam (1.4%) where vaccination programs have been nationwide and routine to all poultry. Ten other countries used vaccine in poultry in a focused, risk-based manner but this accounted for less than 1% of the vaccine used. Most vaccine "failures" have resulted from problems in the vaccination process; i.e., failure to adequately administer the vaccine to at-risk poultry resulting in lack of population immunity, while fewer failures have resulted from antigenic drift of field viruses away from the vaccine viruses. It is currently not feasible to vaccinate wild birds against H5N1 HPAI, but naturally occurring infections with H5 low pathogenicity avian influenza viruses may generate cross-protective immunity against H5N1 HPAI. The most feasible method to prevent and control H5N1 HPAI in wild birds is through control of the disease in poultry with use of vaccine to reduce environmental burden of H5N1 HPAIV, and eventual eradication of the virus in domestic poultry, especially in domestic ducks which are raised in enzootic countries on range or in other outdoor systems having contact with wild aquatic and periurban terrestrial birds.

AB Principal Component Analysis (PCA) is one of the main methods used for electronic nose pattern recognition. However, poor classification performance is common in classification and recognition when using regular PCA. This paper aims to improve the classification performance of regular PCA based on the existing Wilks.-statistic (i.e., combined PCA with the Wilks distribution). The improved algorithms, which combine regular PCA with the Wilks.-statistic, were developed after analysing the functionality and defects of PCA. Verification tests were conducted using a PEN3 electronic nose. The collected samples consisted of the volatiles of six varieties of rough rice (Zhongxiang1, Xiangwan13, Yaopingxiang, WufengyouT025, Pin 36, and Youyou122), grown in same area and season. The first two principal components used as analysis vectors cannot perform the rough rice varieties classification task based on a regular PCA. Using the improved algorithms, which combine the regular PCA with the Wilks.-statistic, many different principal components were selected as analysis vectors. The set of data points of the Mahalanobis distance between each of the varieties of rough rice was selected to estimate the performance of the classification. The result illustrates that the rough rice varieties classification task is achieved well using the improved algorithm. A Probabilistic Neural Networks (PNN) was also established to test the effectiveness of the improved algorithms. The first two principal components (namely PC1 and PC2) and the first and fifth principal component (namely PC1 and PC5) were selected as the inputs of PNN for the classification of the six rough rice varieties. The results indicate that the classification accuracy based on the improved algorithm was improved by 6.67% compared to the results of the regular method. These results prove the effectiveness of using the Wilks A-statistic to improve the classification accuracy of the regular PCA approach. The results also indicate that the electronic nose provides a non-destructive and rapid classification method for rough rice.

TI Structural Equation Modeling Facilitates Transdisciplinary Research on

AB Increasingly, funding agencies are investing in integrated and transdisciplinary research to tackle "grand challenge" priority areas, critical for sustaining agriculture and protecting the environment. Coordinating multidisciplinary research teams capable of addressing these priority areas, however, presents its own unique set of challenges, ranging from bridging across multiple disciplinary perspectives to achieve common questions and methods to facilitating engagement in holistic and integrative thinking that promotes linkages from scholarship to societal needs. We propose that structural equation modeling (SEM) can provide a powerful framework for synergizing multidisciplinary research teams around grand challenge issues. Structural equation modeling can integrate both visual and statistical expression of complex hypotheses at all stages of the research process, from planning to analysis. Three elements of the SEM framework are particularly beneficial to multidisciplinary research teams; these include (i) a common graphical language that transcends disciplinary boundaries, (ii) iterative, critical evaluation of complex hypotheses involving manifest and latent variables and direct and indirect interactions, and (iii) enhanced opportunities to discover unanticipated interactions or causal pathways as empirical data are tested statistically against the model. Using our ongoing multidisciplinary, multisite field investigation of climate change adaptation and mitigation in annual row crop agroecosystems as a case study, we demonstrate the value of the SEM framework for project design, coordination, and implementation and provide recommendations for its broader application as a means to more effectively engage and address issues of critical societal concern.

AB Phytophthora root rot (PRR) is a devastating disease in soybean [Glycine max (L.) Merr.] production. Michigan elite soybean E00003 is resistant to Phytophthora sojae and has been used as a resistance source in breeding. Genetic control of PRR resistance in this source is unknown. To facilitate marker-assisted selection (MAS), the PRR resistance loci in E00003 and their map locations need to be determined. In this study, a genetic mapping approach was used to identify major PRR - resistant loci in E00003. The mapping population consists of 240 F-4-derived lines developed by crossing E00003 with the P. sojae susceptible line PI 567543C. In 2009 and 2010, the mapping population was evaluated in the greenhouse for PRR resistance against P. sojae races 1, 4, and 7, using modified rice (Oryza sativa L.) grain inoculation method. The population was genotyped with seven simple sequence repeat (SSR) and three single nucleotide polymorphism (SNP) markers derived from bulk segregant analysis. The heritability of resistance in the population ranged from 83 to 94%. A major locus, contributing 50 to 76% of the phenotypic variation, was mapped within a 3 cM interval in the Rps1 region. The interval was further saturated with more BARCSOY SSRs and SNPs with TaqMan assays. Two SSRs and three SNPs within the Rps1k gene were highly associated with PRR resistance in the mapping population. The major resistance gene in E00003 is either allelic or tightly linked to Rps1k. The molecular markers located in the Rps1k gene can be used to improve MAS for PRR resistance.

ID MAXIMUM-LIKELIHOOD-ESTIMATION; REGISTRATION; YIELD; MODEL
AB Information regarding genetic variability and correlations of desirable traits provide a reliable basis for cotton (Gossypium hirsutum L.) improvement. The objective of this research was to study the genetics of ginning efficiency and estimate genotypic correlations of ginning energy requirements and ginning rate with some agronomic and quality traits in two upland cotton crosses. F-2 plants from two segregating families were used to produce F-3 plants, from which 62 individual plants from each of the two populations were randomly harvested in 2009 to produce progeny rows which were planted in two replications at two environments at Stoneville, MS during 2010 and 2012. The highest broad-sense heritability was observed for fuzz percentage followed by net ginning energy, gross ginning energy, and ginning rate. Significant positive genotypic correlations were observed between fuzz percentage, net ginning energy, and gross ginning energy. Fuzz percentage, however, had a significant negative genotypic correlation with ginning rate. Ginning rate was negatively and significantly correlated with net ginning energy and gross ginning energy. Net ginning energy had a significant positive genotypic relationship with gross ginning energy. These results hold true for both populations. Results also indicated a high genetic advance from selection for fuzz percentage. These results, coupled with the fact that fuzz percentage is easier, faster, and much less expensive to measure, make it a good candidate for selecting for ginning efficiency.

AB Sucrose is a desirable sugar in soybean seed that affects the quality of soyfoods and feed; therefore, soybean cultivars with high sucrose would be valuable for soyfood and soybean meal markets. The objective of this study was to identify quantitative trait loci (QTL) associated with seed sucrose content using simple sequence repeat (SSR) and single nucleotide polymorphism (SNP) markers that can be used for indirect selection in breeding. A low sucrose line, MFS-553, was crossed with a high sucrose plant introduction, PI 243545, to develop an F-2-derived QTL mapping population. A total of 626 SSR primers covering 20 soybean chromosomes were used to screen the parents and 209 SSR markers were polymorphic. The polymorphic SSR markers were used to genotype 220 F-2:3 lines. Subsequently, a total of 94 F-3:4 lines derived from the initial F-2:3 population were genotyped with 5361 SNP markers spanning 20 chromosomes, of which 2016 were polymorphic. Seed from the F-2:3, F-3:5, and F-3:6 lines were analyzed for sucrose using high performance liquid chromatography (HPLC). Following the linkage map construction, composite interval mapping (CIM) and multiple interval mapping (MIM) were performed to locate sucrose QTL. Three novel QTLs for seed sucrose were mapped to chromosomes 5, 9, and 16, accounting for 46, 10 and 8%, respectively, of the phenotypic variation for sucrose content. SSR and SNP markers linked to these QTLs can be used for marker assisted selection (MAS) in breeding soybean lines with the desired sugar profile.

AB The Lr19 translocation continues to provide broad resistance to Puccinia triticina in many parts of the world and can be particularly useful in resistance gene pyramids. Previously, an associated gene for yellow endosperm pigmentation precluded its use in many countries, and as a result, allosyndetic recombinants and mutants lacking the pigmentation genes have been developed. Such a primary white endosperm recombinant (Lr19-149) and four secondary recombinants (Lr19-149-252, -299, -462, and -478) were obtained in earlier studies. This study characterized the translocations making use of fluorescence genomic in situ hybridization (FGISH), simple sequence repeat (SSR), sequence tagged site (STS), and single nucleotide polymorphism (SNP) markers. The recombined segments were shown to be intercalary inserts of different size and were mapped to the most distal 7BL deletion bin. In addition to a previously reported duplication that involves the Wsp-1 locus, primary recombinant -149 also has a deletion of the PSY-1 containing region. These apparently small aberrations have been retained in three of the secondary recombinants that resulted from single, proximal crossovers. The fourth secondary recombinant (-478) resulted from a distal crossover that apparently restored a normal wheat telomeric region with single copies of the Wsp-B1 and PSY-B1 loci and appears to be the most useful.

AB Interest in soybean [Glycine max (L.) Merr.] isoflavones has increased in recent years owing to numerous reported health benefits. Consequently, quantitative trait loci (QTL) detection for marker-assisted breeding for isoflavones is being examined for genetic gains. This study sought to detect QTL for soybean isoflavones in a population of 274 recombinant inbred lines derived from a cross between 'Essex' and 'Williams 82' that were subdivided and tested by maturity (early, mid, and late). The field tests were conducted in three environments in 2009 (Knoxville, TN; Harrisburg, IL; and Stuttgart, AR). The population was genotyped with 480 polymorphic single nucleotide polymorphism markers. Isoflavones for each replicate were analyzed by near infrared reflectance spectroscopy, whose prediction equation was based on high performance liquid chromatography. Each maturity test, containing 91 or 92 recombinant inbred lines, was analyzed separately for QTL. In total, 21 QTL were detected: 7 for genistein (chromosomes 5, 6, 9, 13, 17, and 19), 5 for daidzein (chromosomes 5, 6, 9, 13, and 19), 3 for glycitein (chromosomes 6, 9, and 20), and 6 for total isoflavone content (chromosomes 5, 6, 9, 13, and 19). Of these 21 QTL, 12 were confirmed or positional confirmations from other studies. Utilization of these QTL could potentially lead to marker-assisted selection approaches for genetic gains in improving soybean isoflavones.

AB Switchgrass (Panicum virgatum L.) is a candidate for cellulosic bioenergy feedstock development in many parts of North America, Europe, and Asia. Breeding for increased biomass yield is a viable and desirable research objective to improve both economic and energy yields per hectare. The objectives of this study were to estimate progress from (i) selection for biomass yield in upland switchgrass, (ii) selection for winter survival, biomass yield, and biomass quality in lowland switchgrass, and (iii) advanced-generation heterosis effects in four upland x lowland hybrid switchgrass populations. Selection for increased biomass yield in upland switchgrass resulted in mean genetic gains for of 0.71 Mg ha(-1) per cycle (8% per cycle = 4% yr(-1)) for biomass yield. Selection for increased biomass yield in lowland switchgrass resulted in mean genetic gains of 0.89 Mg ha(-1) (18% = 1% yr(-1)) for biomass yield. Mean high-parent heterosis between upland and lowland ecotypes was 3.57 Mg ha(-1) (43%). These gains in biomass yield resulted in significant increases in ethanol production for a fermentation platform or high heating value for a combustion platform. Biomass yield is a moderately heritable trait in switchgrass and it can be readily improved in both upland and lowland populations using conventional breeding methods.

POPULATIONS; HERITABILITY; CROPS
AB Commercial viability of switchgrass (Panicum virgatum) as a biofuel will require further improvements of biomass yield to improve sustainability. Direct selection for biomass yield in switchgrass has proven difficult due to the many factors influencing biomass yield. The identification of morphological traits associated with biomass yield could increase the efficiency of breeding efforts if these traits can be used as indirect selection criteria. By allowing increased screening and greater intensity of selection for biomass yield within spaced-plant nurseries, these results may impact how phenotypic selection is used for switchgrass cultivar development. The objective of this research was to identify morphological traits in parental plants that are predictive of biomass yield in progeny swards. Results of this research demonstrate the challenges of selecting for increased biomass yield in switchgrass within spacedplant nurseries. Limited predictive ability was observed using individual and combinations of plant morphological traits. Comparisons of models with varying subsets of traits revealed common traits among the best predictive models including plant height, single-plant dry biomass, and second leaf width. Predictions of single- plant biomass, using the same set of morphological traits, revealed a large effect for tillering related traits. The observation that different traits affect biomass yield differently in the two planting types may indicate an effect of plant competition on the relationship of these traits with biomass yield. While these traits can help guide selections for a preferred plant ideotype, additional efforts to improve selection schemes for increasing biomass yield will be necessary for sustained genetic gain in switchgrass.

HERITABILITY
AB Major efforts are currently being undertaken to improve biomass yield in switchgrass. Among-and-within-family selection has been proposed as an efficient selection scheme to increase rates of genetic gain. The objectives of this study were to estimate the heritability of three yield-related traits (plant height, tiller count, and flowering date) and evaluate the suitability of those traits as within-family-selection criteria. Divergent selections of parents were made for each trait from an upland-tetraploid population developed for use in temperate North America. Progeny from these selections were used to estimate narrow-sense heritability by both parent- progeny regression and response to selection. Moderate heritability (0.41) was estimated for plant height but was greater for selection of increased height. Heritability for tiller count was low overall (0.06), with greater values observed for reduced tillering selections. Flowering date was estimated to have high heritability (0.75) overall in both selection directions. Plant height and flowering date both appear heritable on a spaced-plant basis and may be effective selection criteria for within-family selection. The relative value of among-and-within-family selection within a practical breeding program will vary depending on what selection criteria are used and the timing of selections.

AB A single cytoplasmic source of foxtail millet male sterile lines has become a major limiting factor for wide utilization of heterosis in foxtail millet. To explore genetic diversity of Chinese foxtail millet cytoplasm, 23 pairs of mitochondrial DNA (mtDNA) primers that showed a high level of polymorphism among selected 14 genetically diverse foxtail millet accessions were identified after screening 34 pairs of consensus mtDNA primers that were derived from various plant species. The 23 pairs of primers were used to analyze genetic diversity of cytoplasm in 111 Chinese elite foxtail millet accessions. Genetic similarity coefficients for differentiation of cytoplasmic types were calculated based on the phylogenetic tree and female-parent-derived pedigree graph of all the tested accessions. The results show that the genetic diversity of foxtail millet cytoplasm is low, which makes Chinese foxtail millet germplasm vulnerable to the infection by cytoplasm-related diseases. The 111 tested accessions can be classified into eight cytoplasmic types: Qinyuanmujizui, Huangruangu, Riben60ri, Dahuanggu, Yingsuigu, Heizhigu, MissingI, and MissingII. The eight cytoplasmic types matched with the geographic and ecological distribution pattern of the most tested accessions. The results provided a scientific foundation for rationally utilizing these germplasm lines, diversifying cytoplasmic types in male sterile lines, and further improving hybrid foxtail millet cultivars.

AB Basal stalk rot (BSR) and head rot (HR) caused by Sclerotinia sclerotiorum (Lib.) de Bary are traditionally major diseases of sunflower (Helianthus annuus L.) in the United States, while Phomopsis stem canker (PSC) caused by Phomopsis helianthi Munt.-Cvet. et al. has become increasingly damaging in recent years. Host resistance is the most effective approach to managing these diseases. Here we report new sources of resistance to these diseases identified in the USDA sunflower Plant Introduction (PI) collection. A total of 260 PIs, including USDA-ARS-developed inbred lines, were tested in multiple years and locations of North Dakota, South Dakota, and Minnesota. The effects of genotype (G), environment (E), and G x E interaction were significant. Broad sense heritability (H-2) for BSR, HR, and PSC were estimated as 0.70, 0.79, and 0.83, respectively, reflecting a large genetic variation in the panel for these diseases. A total of 6.2, 29.6, and 36.9% of the genotypes showed significantly higher resistance than checks against BSR, HR, and PSC, respectively. Two PIs, 531389 and 531366, were significantly more resistant than checks against all three diseases. Head rot disease incidence was positively correlated with PSC (r = 0.52, p < 0.0001), while it was negatively correlated with BSR (r = -0.16, p < 0.05). A total of 13 PIs, mostly from Hungary, exhibited dual resistance against HR and PSC. Overall, sufficient variation exists among germplasm sources to facilitate further resistance breeding of sunflower against BSR, HR, and PSC diseases.

AB The genus Daucus includes about 20 recognized species. The most widespread and economically important species, Daucus carota L., occurs on almost every continent. The cultivated carrot, subsp. sativus (Hoffm.) Schubl. and G. Martens, has been selected from wild populations that are extremely diverse, especially in the western Mediterranean. The predominant outcrossing and the lack of sexual isolating mechanisms among recognized infraspecific taxa complicate the taxonomy and identification of the wild populations, resulting in widely different interpretations of the number of infraspecific taxa. We measured 36 morphological characters from multiple individuals within each of 155 accessions of D. carota and from the morphologically similar species D. capillifolius (both species 2n = 18) alongside other species for comparison (D. aureus Desf., 2n = 22; D. broteri Ten., 2n = 20; D. involucratus Sm., 2n = 20; and D. littoralis Sm., 2n = 20) in an experimental field plot. Within D. carota, multivariate analyses were able to identify only two subspecies, but even these showed great overlap of individual characters. Because of the ease of crossability of wild D. carota to the domestic landraces and cultivars and because of the taxonomic challenges, the purpose of our study is to explore morphological support for subspecies within D. carota, including the phenetically similar D. capillifolius, which is part of the same clade as D. carota, with the long-term goal of resolving taxonomic disagreements and developing a practical system to classify variation within this economically important species.

AB Guayule (Parthenium argentatum A. Gray) has tremendous potential as a domestic source of natural rubber production in the southwestern United States. However, genetic improvement of guayule has been slowed by its complex mode of reproduction, natural ploidy series, and lack of genetic and genomic resources. The interspecific hybridization of guayule with its closest sister taxon mariola (P. incanum Kunth) offers an opportunity to access novel genetic variation for guayule breeding programs, but mariola accessions available from the U.S, National Plant Germplasm System (NPGS) have never been evaluated for natural variation in ploidy level. In addition, the nuclear genome sizes for guayule and mariola at any ploidy level are unknown. To that end, we examined the ploidy of 10 mariola accessions, which revealed a natural polyploid series ranging from triploid (2n = 3x = 54) to pentaploid (2n = 5x = 90). In contrast, a ploidy analysis of five guayule accessions uncovered a natural polyploid series that ranged from diploid (2n = 2x = 36) to hexaploid (2n = 6x = 108). More than one ploidy level among individual plants (mixed ploidy) and instances of aneuploid plants were observed for accessions of both guayule and mariola. The nuclear genome sizes of guayule and mariola were similar at identical ploidy levels, and the genome size of diploid guayule (1624 Mb) was almost twofold smaller than the genomes of sunflower (H. annuus L. 2n = 2x = 34) and lettuce (L sativa L.; 2n = 2x = 18), two other Compositae (Asteraceae) species that are being genome-sequenced. The results from this study will serve as a foundation for interspecific breeding and genome sequencing of guayule and mariola. (C) 2014 Elsevier B.V. All rights reserved.

TI Almond hulls as a biofuels feedstock: Variations in carbohydrates by

SO INDUSTRIAL CROPS AND PRODUCTS

DE Almond hulls; Carbohydrates; Sugars; Sugar alcohols; Survey; Biofuels
feedstock
AB Hulls of the almond (Prunus dulcis (Miller) D.A. Webb) have a high content of fermentable sugars (glucose, fructose, sucrose), and are a potential feedstock for biofuels and other uses. The state of California in the United States produces the majority of the world's almonds. Six almond varieties across seven counties in California were studied to assess the amount and variability of sugars and sugar alcohols in the hulls. Previous studies were done over 30 years ago, and don't reflect the current range of varieties and locations. Fermentable sugars ranged from 25 to 33% of the dry weight of the hulls portion of the samples. The "as is" samples contain shells, twigs and other materials that can dilute the concentration of sugars; the Butte and Padre varieties have much higher amounts of shell than the other varieties studied. The Nonpareil variety has the highest fermentable sugars content at an average of 271 kg per tonne of "as is" hulls. Average theoretical ethanol yields ranged from 176 to 130 L/tonne, depending on variety. Finding an economic outlet for the wet, spent hulls is a concern. Published by Elsevier B.V.

AB Camelina (Camelina sativa L.) has gained considerable attention in North America as a potential oilseed feedstock for advanced biofuels and bioproducts. Progress has been made towards characterizing camelina's production potential for the western U.S. and Canada. However, little has been done to evaluate its potential for the north central region of the U.S. The objectives of the following study were to evaluate plant stand establishment, growth, and yield of 10 camelina cultivars and target the optimum sowing time for spring seeding in the northern Corn Belt. The study was conducted over three growing seasons between 2008 and 2010 in west central Minnesota, on a Barnes loam soil. Eight cultivars were evaluated in 2008, 10 cultivars in 2009, and four cultivars in 2010. Sowing dates ranged from 16 April to 15 June over the three-year study. Plant population density, time to 50% flowering, seed yield, and oil content were affected by sowing date, tending to decline with delayed sowing. Seed yield was significantly affected by cultivar only in 2009, whereas oil content was consistently affected by cultivar all three years. Across cultivars, seed yields were as high as 2300 kg ha(-1) to as low as 743 kg ha-1 and were generally greatest for sowings between mid-April to mid-May. Across sowing dates and cultivars, oil content ranged from about 36 to 43% (wt wt(-1)) and declined with delayed sowing. Generally, seed yield and oil content differences tended to be small between most genotypes in the study. Results indicate that the best time to sow spring camelina in west central Minnesota is from about mid-April to mid-May. Further research is needed to optimize other agricultural inputs for camelina production in the northern Corn Belt. Published by Elsevier B.V.

AB Calotropis gigantea (Indian milkweed) is a common plant in Asia that grows as a weed on open waste ground. Flowering and fruiting take place throughout the year. In this study, Indian milkweed oil was evaluated as a potential feedstock for biodiesel production. The oil was extracted from Indian milkweed seeds with hexane in a Soxhlet apparatus. The seeds were found to contain 33.3 wt% oil. The extracted oil was analyzed for the fatty acid profile and oil properties. Several previously unreported minor fatty acids were identified. Because the free fatty acid content in the oil was 27.5 wt%, acid-catalyzed esterification was conducted to esterify free fatty acids and alkali-catalyzed transesterification was performed to produce biodiesel. The triglyceride content, diglyceride content, monoglyceride content, free glycerol, methanol, ester content, carbon residue, acid value, oxidation stability, tocopherol, water content, kinematic viscosity, density, cloud point and flash point of the prepared biodiesel were determined. With the exception of oxidation stability, all fuel properties conformed to four standards (Philippine National Standard PNS2020:2003, Japanese Automotive Standards Organization JASO M360, European Standard EN 14214, American Society for Testing Materials ASTM D6751). However, it was found that this biodiesel can be only used in tropical countries due to the poor cold flow properties. (C) 2014 Elsevier B.V. All rights reserved.

AB Riparian buffers are a proven practice for removing NO3 from overland flow and shallow groundwater. However, in landscapes with artificial subsurface (tile) drainage, most of the subsurface flow leaving fields is passed through the buffers in drainage pipes, leaving little opportunity for NO3 removal. We investigated the feasibility of re-routing a fraction of field tile drainage as subsurface flow through a riparian buffer for increasing NO3 removal. We intercepted an existing field tile outlet draining a 10.1-ha area of a row-cropped field in central Iowa and re-routed a fraction of the discharge as subsurface flow along 335 m of an existing riparian buffer. Tile drainage from the field was infiltrated through a perforated pipe installed 75 cm below the surface by maintaining a constant head in the pipe at a control box installed in-line with the existing field outlet. During 2 yr, > 18,000 m(3) (55%) of the total flow from the tile outlet was redirected as infiltration within the riparian buffer. The redirected water seeped through the 60-m-wide buffer, raising the water table approximately 35 cm. The redirected tile flow contained 228 kg of NO3. On the basis of the strong decrease in NO3 concentrations within the shallow groundwater across the buffer, we hypothesize that the NO3 did not enter the stream but was removed within the buffer by plant uptake, microbial immobilization, or denitrification. Redirecting tile drainage as subsurface flow through a riparian buffer increased its NO3 removal benefit and is a promising management practice to improve surface water quality within tile-drained landscapes.

AB The effects of biochar application to calcareous soils are not well documented. In a laboratory incubation study, a hardwood-based, fast pyrolysis biochar was applied (0, 1, 2, and 10% by weight) to a calcareous soil. Changes in soil chemistry, water content, microbial respiration, and microbial community structure were monitored over a 12-mo period. Increasing the biochar application rate increased the water-holding capacity of the soil-biochar blend, a trait that could be beneficial under water-limited situations. Biochar application also caused an increase in plant-available Fe and Mn, soil C content, soil respiration rates, and bacterial populations and a decrease in soil NO3-N concentration. Biochar rates of 2 and 10% altered the relative proportions of bacterial and fungal fatty acids and shifted the microbial community toward greater relative amounts of bacteria and fewer fungi. The ratio of fatty acid 19: 0 cy to its precursor, 18:1 omega 7c, was higher in the 10% biochar rate soil than in all other soils, potentially indicating an environmental stress response. The 10% application rate of this particular biochar was extreme, causing the greatest change in microbial community structure, a physiological response to stress in Gram-negative bacteria, and a drastic reduction in soil NO3-N (85-97% reduction compared with the control), all of which were sustained over time.

AB Manure from beef cattle feedyards is a valuable source of nutrients and assists with maintaining soil quality. However, humification and decomposition processes occurring during feedyard manure's on-farm life cycle influence the forms, concentrations, and availability of carbon (C) and nutrients such as nitrogen (N) and phosphorus (P). Improved understanding of manure organic matter (OM) chemistry will provide better estimates of potential fertilizer value of manure from different feedyard sources (e. g., manure accumulated in pens, stockpiled manure after pen scraping) and in settling basin and retention pond sediments. This will also assist with identifying factors related to nutrient loss and environmental degradation via volatilization of ammonia and nitrous oxide and nitrate leaching. We used Fourier-transform infrared (FTIR) and ultraviolet-visible (UV-vis) spectroscopies to characterize structural and functional properties of OM and water-extractable OM (WEOM) from different sources (surface manure, manure pack, settling basin, retention pond) on a typical commercial beef feedyard in the Texas Panhandle. Results showed that as beef manure completes its on-farm life cycle, concentrations of dissolved organic C and N decrease up to 98 and 95%, respectively. The UV-vis analysis of WEOM indicated large differences in molecular weight, lignin content, and proportion of humified OM between manures from different sources. The FTIR spectra of OM and WEOM indicate preferential decomposition of fats, lipids, and proteins over aromatic polysaccharides such as lignin. Further work is warranted to evaluate how application of feedyard manure from different sources influences soil metabolic functioning and fertility.

AB The fate of [C-14]17 beta-estradiol ([C-14]E2) was monitored for 42 d in triplicate 10-L anaerobic digesters. Total radioactive residues decreased rapidly in the liquid layer of the digesters and reached a steady-state value of 22 to 26% of the initial dose after 5 d. High-performance liquid chromatography and liquid chromatographytandem mass spectrometry analyses of the liquid layer of the anaerobic digesters indicated a rapid degradation of E2 to estrone (E1), which readily adsorbed to the sludge layer subsequent to its formation. Estrone was the predominant steroid identified under anaerobic digestion in the liquid layer or sorbed to sludge at 42 d. Methane formation represented 11.1 +/- 5.7% of the initial E2 fortification with 0.3 to 0.5% of the starting E2 mineralized to carbon dioxide. Maximum [C-14] methane production appeared between Days 4 and 7. An estimate of estrogenicity of the final product based on reported estrogen equivalents for E1 and E2 was 2% of the original in active digesters. Anaerobic digestion of swine waste has several management benefits; moreover, this study demonstrated that it reduces the potential of environmental release of estrogens, which are known endocrine disruptors.

AB The ability to monitor whole canopy CO2 and H2O fluxes of crop plants in the field is needed for many research efforts ranging from plant breeding to the study of climate change effects on crops. Four portable, transparent, open system chambers for measuring canopy gas exchanges were field tested on well-watered and fertilized cotton (Gossypium hirsutum L.) over 6 d at Lubbock, TX, in 2010. Our objective was to (i) characterize changes in canopy microclimate variables due to chamber enclosure and (ii) evaluate chamber-to-chamber variability in canopy gas-exchange parameters on ground as well as leaf area basis. Chamber wall materials reduced photosynthetically active radiation (PAR) by about 13%. Programmable data loggers controlled variable speed fans and, with one minor exception, limited heat buildup in the chambers to a maximum of <1.0 degrees C above ambient air temperature. Differentials between incoming and outgoing atmospheric CO2 and H2O concentrations were used to calculate canopy net assimilation (A) and transpiration (E) at 10-s intervals using solenoid valve actuated sample lines connected to an infrared gas analyzer. Water use efficiency (WUE = A/E) was then calculated and these data were averaged over both 5-min and hourly intervals. Coefficient of variation (CV) for midday A, E, and WUE averaged 12.3, 9.7, and 5.8%, respectively. Expressing these parameters on a canopy leaf area basis produced similar CV results. These results will help guide experimental design for future research using these or similar chambers.

AB Net CO2 exchange data of legume crops at 17 flux tower sites in North America and three sites in Europe representing 29 site-years of measurements were partitioned into gross photosynthesis and ecosystem respiration by using the nonrectangular hyperbolic light-response function method. The analyses produced net CO2 exchange data and new ecosystem-scale ecophysiological parameter estimates for legume crops determined at diurnal and weekly time steps. Dynamics and annual totals of gross photosynthesis, ecosystem respiration, and net ecosystem production were calculated by gap filling with multivariate nonlinear regression. Comparison with the data from grain crops obtained with the same method demonstrated that CO2 exchange rates and ecophysiological parameters of legumes were lower than those of maize (Zea mays L.) but higher than for wheat (Triticum aestivum L.) crops. Year-round annual legume crops demonstrated a broad range of net ecosystem production, from sinks of 760 g CO2 m(-2) yr(-1) to sources of -2100 g CO2 m(-2) yr(-1), with an average of -330 g CO2 m(-2) yr(-1), indicating overall moderate CO2-source activity related to a shorter period of photosynthetic uptake and metabolic costs of N-2 fixation. Perennial legumes (alfalfa, Medicago sativa L.) were strong sinks for atmospheric CO2, with an average net ecosystem production of 980 (range 550-1200) g CO2 m(-2) yr(-1).

TI Yield Gaps and Yield Relationships in Central US Soybean Production

LA English
DT Article
ID AGRICULTURE; MANAGEMENT; CHINA; POTENTIALS; QUALITY; CLIMATE; TRENDS;
DEPTH; PLAIN
AB The magnitude of yield gaps (YG) (potential yield-farmer yield) provides some indication of the prospects for increasing crop yield. Quantile regression analysis was applied to county soybean [Glycine max (L.) Merr.] yields (1972-2011) from Kentucky, Iowa, and Nebraska (irrigated) to estimate the attainable potential yield (APY) (yield in the most favorable environments in the 40-yr record). The YG for each year was the difference between the APY and the county yield. There was substantial variation in the 40-yr mean county yields (186-335 g m(-2)) within and among states. The mean county APY within each state increased linearly (P < 0.0001) in conjunction with mean county yields. The mean relative YGs varied from 9 to 24% of APY and were largest in the lowest yielding counties and they decreased linearly (P < 0.0001) as the mean county yield increased for each state. The large YGs were partially related to very low yields that occurred in some years during the 40-yr period and these YGs may partially reflect the ability of the soil to supply water to the crop. The difference between the maximum APY in each state and each county APY defined a second YG. The largest values ranged from 12 to 19% of the maximum APY. Irrigation should partially eliminate the first YG, but the second may be more intractable to the degree it is related to soil characteristics. These results suggest that soil conditions may play an important role in determining the size of YGs.

TI Field-Specific Fertilizer Nitrogen Requirements for First-Year Corn
following Alfalfa

DT Article
ID CROPPING SYSTEM; YIELD RESPONSE; SOIL-NITROGEN; GRAIN-YIELD; DRY-MATTER;
TILLAGE; ROTATIONS; CROPS; TESTS; RECOMMENDATIONS
AB Current fertilizer N guidelines in the midwestern and northeastern United States may not adequately account for variable N supply to corn (Zea mays L.) grown after alfalfa (Medicago sativa L.). Nitrogen supplied by alfalfa often is adequate for optimum grain yield of the subsequent corn crop, but fertilizer N sometimes is needed. Using 259 site-years of data from midwestern and northeastern United States literature and multiple logistic regression analysis, we successfully identified binary response categories (statistically significant or nonsignificant) to fertilizer N in first-year corn following alfalfa in 89 to 97% of the cases on fine-textured soils and on medium-textured soils with spring-terminated alfalfa, and in 73 to 90% of the cases on medium-textured soils with fall-terminated alfalfa. Only 1 of 11 site-years on coarse-textured soils did not require fertilizer N, preventing separation of responsive and nonresponsive site-years. Using multiple linear regression analysis, >= 68% of the variation in actual economically optimum nitrogen rate (EONR) across a range of price ratios (PRs) (4.48-11.2 as US$ kg(-1) N/US$ kg(-1) grain) was explained on fine-, medium-, and coarse-textured soils by simple predictors-alfalfa termination time, alfalfa stand age, and weather conditions from October through spring. Although independent data are needed to validate the equations, this approach to field-specific fertilizer N guidelines for first-year corn following alfalfa appears, in many cases, to identify when no N is needed and provide improved rate estimates when N response is expected. This approach to fertilizer N recommendation may prove effective for other rotations.

TI Second-Year Corn after Alfalfa Often Requires No Fertilizer Nitrogen
SO AGRONOMY JOURNAL

ID 1ST-YEAR CORN; RESIDUE MANAGEMENT; NITRATE TESTS; SOIL; TILLAGE;
AVAILABILITY; RECOMMENDATIONS; CREDIT; MANURE; TIME
AB Terminated alfalfa (Medicago sativa L.) often provides N to at least 2 yr of subsequent corn (Zea mays L.) crops, but the variability in fertilizer N guidelines for second-year corn in the midwestern United States needs to be addressed. In several states, fertilizer N guidelines are the same for second-year corn after alfalfa as they are for continuous corn, whereas other states recommend reducing fertilizer N rates to second-year corn by 25 to 145 kg N ha(-1). Experiments were conducted at 28 farms in Iowa and Minnesota to determine fertilizer N requirements of second-year corn after alfalfa. Second-year corn in half of the trials showed no response to fertilizer N and the economically optimum N rate (EONR) for corn grain yield in the 14 responsive trials ranged from <= 67 to 196 kg N ha(-1). Furthermore, in 10 of 19 trials there was no response of grain yield to fertilizer N in both first- and second-year corn. These results indicate that current university fertilizer N guidelines for second-year corn after alfalfa often are unreliable. At the widely adopted critical concentration of 21 mg kg(-1), the pre-sidedress soil nitrate test (PSNT) correctly identified only 63% of the trials as responsive or nonresponsive to fertilizer N. When results of our experiments were combined with data from the literature, second-year corn grain yield responded to fertilizer N 55% of the time and the PSNT remained accurate only 65% of the time, indicating that more accurate forecasting of second-year corn N requirements is needed.

AB Nitrogen rate studies were conducted under furrow-irrigated corn (Zea mays L.) production on a silty clay soil to compare granular urea with polymer-coated urea (PCU) and stabilized urea (SU, contains urease and nitrification inhibitors) effects on corn yields, plant N uptake, and N use efficiency. Polymer-coated urea had a yield advantage over urea 2 (continuous corn) of 3 yr at N rates below maximum yield, which resulted in greater economic returns with PCU (4-14%) at N rates from 168 to 280 kg N ha(-1). The SU fertilizer had no yield or economic advantage over urea. Grain and stover yields and N uptake increased with increasing N rate for all N sources. Expressing grain yields from all N sources as a linear-plateau function of N rate showed that yields were maximized at 14.3 Mg ha(-1) at an N rate of 254 kg N ha(-1) or available N level (soil NO3-N plus fertilizer N) of 295 kg N ha(-1). Nitrogen recovery efficiency (RE) tended not to vary with N rate, with no differences between SU and urea but greater RE (19%) with PCU than urea under continuous corn. Fertilizer N use efficiency did not vary with N rate but was greater for PCU (36%) than for urea (32%) under continuous corn. In contrast to SU, PCU provided grain yield and potential economic advantages over urea under continuous corn production at N rates below those needed with urea for maximum grain yield.

AB Fertilizer application in crop production agriculture is a major factor influencing soil emissions of the greenhouse gas N2O. Enhanced efficiency fertilizers (EEFs) have the potential to decrease N2O emissions by improving the synchrony between soil N supply and crop N demand. This study was conducted to compare the effects of N2O emissions from soil cropped to corn (Zea mays L.) and EEFs and conventional fertilizers. During a 3-yr period, growing-season N2O emissions were quantified in unfertilized check plots and plots fertilized with urea-NH4NO3 (UAN), UAN containing the urease and nitrification stabilizer AgrotainPlus (UAN+Ag), a stabilized urea containing urease and nitrification inhibitors (SuperU), and a controlled-release polymer-coated urea (ESN). In the third year of the study, conventional urea and an additional fertilizer formulation, Nutrisphere, were evaluated. We observed no reductions in cumulative seasonal N2O emissions from treatments fertilized with the EEFs in any of the study years. Generally, N2O emissions were significantly higher than emissions from the check (no fertilizer) treatment. There were no differences among fertilizer types except in 2009 when the ESN treatment had significantly higher emissions than the check, UAN, and UAN+Ag treatments. Our results indicate that, due to the episodic nature of N2O emissions induced by rainfall events, reduction of N2O emissions through the use of EEFs may be limited in rainfed regions.

AB Irrigation and N fertilizer management are important factors affecting crop yield, N fertilizer recovery efficiency, and N losses as nitrous oxide (N2O) and nitrate (NO3-). Split application of conventional urea (split-U) and/or one-time application of products designed to perform as enhanced-efficiency N fertilizers may mitigate N losses. The objective of this study was to compare the effects of controlled-release polymer-coated urea (PCU), stabilized urea with urease and nitrification inhibitors (IU) and split-U on direct soil-to-atmosphere N2O emissions, NO3- leaching, and yield for fully irrigated and minimum-irrigated corn in loamy sand. Indirect N2O emissions due to NO3- leaching were estimated using published emission factors (EF5). Split-U increased yield and N uptake compared with preplant-applied PCU or IU and decreased NO3- leaching compared with PCU. Direct N2O emissions were significantly less with IU or split-U than with PCU, and there was a trend for greater emissions with split-U than with IU (P = 0.08). Irrigation significantly increased NO3- leaching during the growing season but had no significant effect on direct N2O emissions. After accounting for significantly increased yields with irrigation, however, N losses expressed on a yield basis did not differ and in some cases decreased with irrigation. Post-harvest soil N and soil-water NO3- in spring showed the potential for greater N leaching in minimum-irrigated than fully irrigated plots. Indirect emissions due to NO3- leaching were estimated to be 79 to 117% of direct emissions using the default value of EF5, thus signifying the potential importance of indirect emissions in evaluating management effects on N2O emissions.

AB Enhanced-efficiency N fertilizers (EENFs) have potential for mitigating N2O emissions from N-fertilized cropping systems. Stabilized EENFs contain nitrification and/or urease inhibitors. Slow-release EENFs contain N components that are slowly released with variable release rates. Controlled-release EENFs release N at more predictable rates. The effectiveness of several EENFs in reducing soil N2O emissions from a clay loam soil under irrigated, corn (Zea mays L.)-based production systems in Colorado (2002-2012) was investigated. A controlled-release, polymer-coated urea, ESN, reduced N2O emissions by 42% compared with urea and 14% compared with urea-NH4NO3 solution (UAN) in no-till and strip-till environments, but had no effect in a conventional tillage environment. A stabilized urea source, SuperU, reduced N2O emissions by 46% compared with urea and 21% compared with UAN. A stabilized UAN source, UAN + AgrotainPlus, reduced N2O emissions by 61% compared with urea and 41% compared with UAN alone. A slow-release UAN source, UAN + Nfusion, reduced N2O emissions by 57% compared with urea and 28% compared with UAN. Urea-NH4NO3 reduced N2O emissions by 35% compared with urea. A linear increase in N2O emissions with increasing N rate was observed for untreated urea and UAN. Developers of management protocols to reduce N2O emissions from irrigated cropping systems in semiarid areas can use this information to estimate reductions in N2O emissions when EENFs are used. Policymakers can use this information to help determine financial credits needed to encourage producers to use these technologies in their crop production systems.

AB The use of enhanced efficiency N fertilizers can increase crop N utilization and lead to lower emissions of the greenhouse gas N2O. To determine the potential benefit of four enhanced efficiency fertilizers with rainfed corn (Zea mays L.) production in central Pennsylvania, N2O emissions and grain yield were monitored during a 4-yr field study and compared with untreated urea prills and urea-NH4NO3 (UAN). The tested enhanced efficiency products were ESN (polymer-coated urea), SuperU (urease and nitrification inhibitor treated urea), UAN treated with AgrotainPlus (urease and nitrification inhibitors), and PiNT (cation-stabilized amine-N). Additionally, 28-d laboratory incubations were conducted to verify the potential differences in N cycling rates among N sources. The laboratory incubations indicated that ESN, SuperU, and treated UAN all had the potential to delay accumulation of NO3 relative to untreated urea and UAN, but N cycling was similar with PiNT and the untreated fertilizers. Extended dry periods limited the denitrification potential and overall N2O emissions in the field, but spikes of N2O emission were seen within 1 mo after fertilizer application in each year. However, variation in emission rates was high within treatments, and no consistent differences among N sources were seen. Cumulative growing season N2O emissions and grain yield were similar for all N sources in each year of the study. Enhanced efficiency fertilizers do not appear to be an effective means to reduce N2O emission in a rainfed system, at least when rainfall is inconsistent.

AB Interest in the use of enhanced-efficiency nitrogen fertilizer (EENFs) sources has increased in recent years due to the potential of these new EENF sources to increase crop yield, while at the same time decreasing N loss from agricultural fields. The efficacy of these fertilizer sources on cotton (Gossypium hirsutum L.) production in southeastern U.S. upland soils has not been well documented. Thus, a field study was conducted on a Coastal Plain soil (Marvyn loamy sand; fine-loamy, kaolinitic, thermic Typic Kanhapludult) in Central Alabama from 2009 to 2011 to compare EENFs to traditional N sources in a high-residue conservation cotton production system. Nitrogen fertilizer sources evaluated included urea (U), ammonium sulfate (AS), urea-ammonium sulfate (UAS), Environmentally Smart Nitrogen (ESN) (Agrium Advanced Technologies, Loveland, CO), stabilized urea (SuperU [SU] [Agrotain International, St. Louis, MO]), poultry litter (PL), poultry litter + AgrotainPlus (PLA) (KOCH Agronomic Services LLC, Wichita, KS), and an unfertilized control (C). Generally, no significant differences in cotton lint yield were observed between the traditional sources and EENFs. Nitrogen source affected fiber quality; however, effects varied among years and generally would not have impacted discount/premium values. In the present study, EENFs produced cotton lint yields similar to conventional fertilizers, suggesting their higher cost may render them uncompetitive at present. However, if EENFs reduce N loss through leaching, runoff and N2O flux from agricultural fields they could become viable alternative fertilizer sources. More research is needed on the benefits of enhanced-efficiency fertilizer use as a tool in agricultural production systems.

AB Nitrogen is one of the most important and costly nutrient inputs for crop production. Farmers are looking for better management practice to enhance production and reduce environmental impact. A 3-yr field study was established to examine corn (Zea mays L.) grain yield and nutrient uptake resulting from application of 168 kg N ha(-1) as urea (U), urea-ammonium nitrate (UAN), ammonium nitrate (NH4NO3), poultry litter (PL), and similar rate of commercially available enhanced-efficiency nitrogen fertilizers (EENF) as follow: polymer-coated urea (ESN), SuperU, UAN + AgrotainPlus, and PL + AgrotainPlus in a no-till corn production. Treatments were replicated four times in a completely randomized block design from 2009 to 2011. Aboveground plant biomass was harvested at physiological maturity each year to determine dry matter and nutrient uptake. Soil samples were taken three times per year to evaluate the status of the selected nutrients in soil. There was a significant increase in corn aboveground dry matter and grain yield with application of 168 kg N ha(-1) compared with control treatment. There was no significant difference in corn grain yield or dry matter among the N sources. However, averaged across all N sources, corn grain yield (10.1 Mg ha(-1)) in 2009 was greater than grain yield (7.5 Mg ha(-1)) in 2010 and 2011, mainly due to higher rainfall and better distribution in 2009. Addition of AgrotainPlus to UAN and PL did not influence corn grain yield. Additional research is needed to evaluate EENFs under different climatic conditions and different management practices.

AB Management of N in corn (Zea mays L.) production systems attempts to increase crop yields and minimize environment impact. This study evaluated enhanced efficiency fertilizers (EEFs) compared to their non-EEF forms on grain yield and corn biomass at the beginning of the grain-filling period, leaf chlorophyll index (CI) measurements, spectral reflectance, and leaf area index throughout the growing season. These studies were conducted on a continuous corn study from 2008 through 2010 stabilized urea with urease and nitrification inhibitors (SuperU [Koch Agronomic Services, Wichita, KS]), urea-ammonium nitrate (UAN) with and without a urease and nitrification inhibitor (AgrotainPlus [Koch Agronomic Services, Wichita, KS]), and environmentally smart nitrogen polymer coated urea (ESN [Agrium Advanced Technologies, Loveland, CO]). There was no significant effect of EEFs compared to non-EEF materials on the biomass or leaf area indices (LAI) at the end of vegetative development; however, there were consistently higher yields with the EEF materials. Differences in yield were related to increased leaf CI values during the grain-filling period and a summation index based on leaf CI was linearly related to grain yield. Use of the EEF materials decreased the rate of leaf senescence with a linear relationship for each year but not a common relationship among years. Application of EEF materials to corn produced a positive impact on grain yield through the increased ability of the corn canopy to maintain green leaf area, capture photosynthetically active radiation (PAR) and convert this energy into larger yields. The effect of EEF materials on improved grain-fill under rainfed conditions of the central Corn Belt provides effective N management strategies to increase yield.

AB Flash floods can cause extensive damage to both life and property, especially because they are difficult to predict. Flash flood prediction requires high-resolution meteorological observations and predictions, as well as calibrated hydrological models, which should effectively simulate how a catchment filters rainfall inputs into streamflow. Furthermore, because of the requirement of both hydrological and meteorological components in flash flood forecasting systems, there must be extensive data handling capabilities built in to force the hydrological model with a variety of available hydrometeorological data and predictions, as well as to test the model with hydrological observations. The authors have developed a working prototype of such a system, called KINEROS/hsB-SM, after the hydrological models that are used: the Kinematic Erosion and Runoff (KINEROS) and hillslope-storage Boussinesq Soil Moisture (hsB-SM) models. KINEROS is an event-based overland flow and channel routing model that is designed to simulate flash floods in semiarid regions where infiltration excess overland flow dominates, while hsB-SM is a continuous subsurface flow model, whose model physics are applicable in humid regions where saturation excess overland flow is most important. In addition, KINEROS/hsB-SM includes an energy balance snowmelt model, which gives it the ability to simulate flash floods that involve rain on snow. There are also extensive algorithms to incorporate high-resolution hydrometeorological data, including stage III radar data (5 min, 1 degrees by 1 km), to assist in the calibration of the models, and to run the model in real time. The model is currently being used in an experimental fashion at the National Weather Service Binghamton, New York, Weather Forecast Office.

TI Decreased Relative Diagnostic Yield of Esophagogastroduodenoscopy in
Children With Gastroparesis
SO JOURNAL OF CLINICAL GASTROENTEROLOGY

ID GASTRIC-EMPTYING SCINTIGRAPHY; DYSPEPSIA; SOLIDS
AB Background:Esophagogastroduodenoscopy (EGD) and gastric emptying scintigraphy (GES) are commonly performed in the evaluation of children with upper gastrointestinal symptoms. It has been presumed, but not clarified, that gastroparesis increases the likelihood of identifying abnormalities on EGD. We sought to determine whether the presence of gastroparesis influenced the diagnostic yield of EGD in children.Methods:We conducted a retrospective chart review of children who underwent both an EGD and GES within 3 months of each other for evaluation of upper gastrointestinal symptoms (eg, abdominal pain). Clinical history (symptoms, comorbidities, medications, and surgical procedures), GES results, and EGD histology reports were captured.Results:A total of 125 children (46% female) were included, of whom, 70 (56%) had gastroparesis. Thirty-three (26%) children had liquid meal GES (1.21.1 y of age, mean +/- SD) and 92 (64%) had solid meal GES (12.4 +/- 3.6 y of age). There was an overall trend toward a decreased frequency of biopsy abnormalities in those with gastroparesis (P=0.09). Those with gastroparesis identified through liquid meal GES were less likely to have reflux esophagitis on biopsy (P=0.002). Those with gastroparesis identified on solid meal GES were less likely to have gastritis (P=0.04). Symptoms, comorbidities, or medications were not predictive of GES or EGD results.Conclusions:Children with gastroparesis may be less likely to have biopsy abnormalities identified on EGD in comparison to those without gastroparesis. Further prospective, larger, and multicenter studies are needed to validate our findings.

ID INFLAMMATORY-BOWEL-DISEASE; NECROSIS-FACTOR-ALPHA; CHILDREN;
COMPLICATIONS; THERAPY; COHORT
AB Background:Infliximab (IFX) is an established treatment modality for moderate to severe pediatric ulcerative colitis (UC). The purpose of this study was to identify clinical and laboratory parameters, which predict response to IFX in pediatric UC defined by colectomy as the primary outcome measure. Postsurgical complications were examined as well.Methods:A retrospective chart review was performed on children younger than 19 years who received IFX therapy at Texas Children's Hospital, Houston, Texas for the treatment of UC from January 2005 to April 2012. Demographics, laboratory data, clinical subtype, duration of disease, transfusion requirement, number of IFX infusions, concurrent medications, and postoperative complication with regard to IFX exposure were examined.Results:Forty-seven patients (22 male and 25 female; average age at diagnosis: 11.4 y) received IFX. Twenty-six (55.3%) required colectomy, 20 (42.6%) of which occurred within a year of therapy initiation. Disease duration <20 months before IFX initiation, increased the likelihood of a colectomy within a year [OR: 3.8 (95% CI, 1.6-13.3), P=0.044]. Blood transfusion requirement before IFX was associated with higher rates of colectomy within a year [OR: 9.78 (95% CI, 2.2-43.3), P=0.0028]. Preoperative exposure to IFX within 8 weeks did not significantly increase postoperative complications (P=0.26). Serum albumin levels at diagnosis did not predict colectomy.Conclusions:Shorter disease duration and need for blood transfusion may be useful indicators of limited response to IFX in pediatric UC.

DT Article
DE Enzyme-linked immunosorbent assay; highly pathogenic avian Influenza A
virus subtype H5N1; swine
ID INFECTION; PIGS
AB A potential mechanism by which highly pathogenic avian Influenza A virus subtype H5N1 could more readily infect human beings is through the infection of and adaptation in pigs. To detect the occurrence of such infection, monitoring of pig populations through serological screening would be highly desirable. In the current study, hemagglutination inhibition assays were able to detect antibodies against H5N1 developed in pigs, but because of antigenic variation between clades, the use of multiple virus strains were required. Whole recombinant virus and recombinant hemagglutinin antigen enzyme-linked immunosorbent assays (ELISAs) were generated that could detect antibody against multiple H5N1 strains, but which also detected antibody against endemic swine influenza viruses. A recombinant hemagglutinin antigen-based ELISA was as effective as the whole virus antigen ELISAs in detecting antibody against the H5N1 virus strains used and eliminated nearly all of the cross-reactivity with non-H5N1 virus antibody. The current study also highlighted the difficulty in establishing a decision (cutoff) value that would effectively counterbalance nonspecific reactivity against sensitivity. The results provide important information and considerations for the development of serological screening assays for highly pathogenic avian H5N1 viruses.

SO JOURNAL OF VETERINARY DIAGNOSTIC INVESTIGATION
LA English
DT Article
DE Polymerase chain reaction; squirrels; tularemia
ID TULAREMIA; HOLARCTICA
AB Fifteen cases of Francisella tularensis infection (tularemia) were identified in western gray (Sciurus griseus) and eastern gray (Sciurus carolinensis) squirrels submitted to the Washington Animal Disease Diagnostic Laboratory between 2008 and 2011. All of the squirrels originated in Washington State, a geographical area with endemic tularemia in wildlife. Nine of the 15 squirrels with F. tularensis infection had gross (2/15) or microscopic (9/15) multifocal necrotizing lesions in the spleen, liver, or lymph nodes, typical of tularemia. Special stains did not reliably identify intralesional bacteria microscopically. Six of the 15 squirrels infected with F. tularensis lacked gross and microscopic lesions typical of tularemia. All 15 squirrels with F. tularensis infection were identified by polymerase chain reaction tests on the spleen, liver, or lymph node (including all 6 squirrels without typical tularemia lesions); 8 out of 9 squirrels were positive by direct fluorescent antibody test of tissues, and 5 out of 15 squirrels were positive by culture of tissues. The findings underscore the importance of considering tularemia as a possible cause of death when no lesions of tularemia can be identified at necropsy. Furthermore, the findings suggest the possibility of subclinical infections in gray squirrels, and the importance of molecular diagnostics for definitive diagnosis of F. tularensis infection in wild squirrels.

AB Observational studies have suggested that with time, some diseases result in a characteristic odor emanating from different sources on the body of a sick individual. Evolutionarily, however, it would be more advantageous if the innate immune response were detectable by healthy individuals as a first line of defense against infection by various pathogens, to optimize avoidance of contagion. We activated the innate immune system in healthy individuals by injecting them with endotoxin (lipopolysaccharide). Within just a few hours, endotoxin-exposed individuals had a more aversive body odor relative to when they were exposed to a placebo. Moreover, this effect was statistically mediated by the individuals' level of immune activation. This chemosensory detection of the early innate immune response in humans represents the first experimental evidence that disease smells and supports the notion of a "behavioral immune response" that protects healthy individuals from sick ones by altering patterns of interpersonal contact.

AB The conservation of species at risk of extinction requires data to support decisions at landscape to regional scales. There is a need for information that can assist with locating suitable habitats in fragmented and degraded landscapes to aid the reintroduction of at-risk plant species. In addition, desiccation and water stress can be significant barriers to the success of at-risk plant reintroduction programs. We examine how airborne light detection and ranging (LiDAR) data can be used to model microtopographic features that reduce water stress and increase resource availability, providing information for landscape planning that can increase the success of reintroduction efforts for a dryland landscape in Hawaii. We developed a topographic habitat-suitability model (HSM) from LiDAR data that identifies topographic depressions that are protected from prevailing winds (high-suitability sites) and contrasts them with ridges and other exposed areas (low-suitability sites). We tested in the field whether high-suitability sites had microclimatic conditions that indicated better-quality habitat compared to low-suitability sites, whether plant-response traits indicated better growing conditions in high-suitability sites, whether the locations of individuals of existing at-risk plant species corresponded with our habitat-suitability classes, and whether the survival of planted individuals of a common native species was greater in high-suitability, compared to low-suitability, planting sites. Mean wind speed in a high-suitability field site was over five times lower than in a low-suitability site, and soil moisture and leaf wetness were greater, indicating less stress and greater resource availability in high-suitability areas. Plant height and leaf nutrient content were greater in high-suitability areas. Six at-risk species showed associations with high-suitability areas. The survival of planted individuals was less variable among high-suitability plots. These results suggest that plant establishment and survival is associated with the habitat conditions identified by our model. The HSM can improve the survival of planted individuals, reduce the cost of restoration and reintroduction programs through targeted management activities in high-suitability areas, and expand the ability of managers to make landscape-scale decisions regarding land-use, land acquisition, and species recovery.

AB Interacting threats to ecosystem function, including climate change, wildfire, and invasive species necessitate native plant restoration in desert ecosystems. However, native plant restoration efforts often remain unguided by ecological genetic information. Given that many ecosystems are in flux from climate change, restoration plans need to account for both contemporary and future climates when choosing seed sources. In this study we analyze vegetative responses, including mortality, growth, and carbon isotope ratios in two blackbrush (Coleogyne ramosissima) common gardens that included 26 populations from a range-wide collection. This shrub occupies ecotones between the warm and cold deserts of Mojave and Colorado Plateau ecoregions in western North America. The variation observed in the vegetative responses of blackbrush populations was principally explained by grouping populations by ecoregions and by regression with site-specific climate variables. Aridity weighted by winter minimum temperatures best explained vegetative responses; Colorado Plateau sites were usually colder and drier than Mojave sites. The relationship between climate and vegetative response was mapped within the boundaries of the species-climate space projected for the contemporary climate and for the decade surrounding 2060. The mapped ecological genetic pattern showed that genetic variation could be classified into cool-adapted and warm-adapted ecotypes, with populations often separated by steep clines. These transitions are predicted to occur in both the Mojave Desert and Colorado Plateau ecoregions. While under contemporary conditions the warm-adapted ecotype occupies the majority of climate space, climate projections predict that the cool-adapted ecotype could prevail as the dominant ecotype as the climate space of blackbrush expands into higher elevations and latitudes. This study provides the framework for delineating climate change-responsive seed transfer guidelines, which are needed to inform restoration and management planning. We propose four transfer zones in blackbrush that correspond to areas currently dominated by cool-adapted and warm-adapted ecotypes in each of the two ecoregions.

AB Produce contaminated with enteric pathogens is a major source of foodborne illness in the United States. Lakes, streams, rivers, and ponds were sampled with Moore swabs bi-monthly for over 2 years at 30 locations in the vicinity of a leafy green growing region on the Central California Coast and screened for Shiga toxin producing Escherichia coli (STEC), Salmonella enterica, and Listeria monocytogenes to evaluate the prevalence and persistence of pathogen subtypes. The prevalence of STEC from 1386 samples was 11%; 110 samples (8%) contained E. coli O157:H7 with the highest prevalence occurring close to cattle operations. Non-O157 STEC isolates represented major clinical O-types and 57% contained both shiga toxin types 1 and 2 and intimin. Multiple Locus Variable Number Tandem Repeat Analysis of STEC isolates indicated prevalent strains during the period of study. Notably, Salmonella was present at high levels throughout the sampling region with 65% prevalence in 1405 samples resulting in 996 isolates with slightly lower prevalence in late autumn. There were 2, 8, and 14 sites that were Salmonella-positive over 90, 80, and 70% of the time, respectively. The serotypes identified most often were 6,8:d:-, Typhimurium, and Give. Interestingly, analysis by Pulsed Field Gel Electrophoresis indicated persistence and transport of pulsotypes in the region over several years. In this original study of L. monocytogenes in the region prevalence was 43% of 1405 samples resulting in 635 individual isolates. Over 85% of the isolates belonged to serotype 4b with serotypes 1/2a, 1/2b, 3a, 4d with 4e representing the rest, and there were 12 and 2 sites that were positive over 50 and 80% of the time, respectively. Although surface water is not directly used for irrigation in this region, transport to the produce can occur by other means. This environmental survey assesses initial contamination levels toward an understanding of transport leading to produce recalls or outbreaks.

AB Johne's disease (JD) caused by Mycobacterium avium subspecies paratuberculosis (MAP) is a major threat to the dairy industry and possibly some cases of Crohn's disease in humans. A MAP vaccine that reduced of clinical disease and/or reduced fecal shedding would aid in the control of JD. The objectives of this study were (1) to evaluate the efficacy of 5 attenuated strains of MAP as vaccine candidates compared to a commercial control vaccine using the protocol proposed by the Johne's Disease Integrated Program (JDIP) Animal Model Standardization Committee (AMSC), and (2) to validate the AMSC Johne's disease goat challenge model. Eighty goat kids were vaccinated orally twice at 8 and 10 weeks of age with an experimental vaccine or once subcutaneously at 8 weeks with Silirum (R) (Zoetis), or a sham control oral vaccine at 8 and 10 weeks. Kids were challenged orally with a total of approximately 1.44 x 10(9) CFU divided in two consecutive daily doses using MAP ATCC-700535 (K10-like bovine isolate). All kids were necropsied at 13 months post-challenge. Results indicated that the AMSC goat challenge model is a highly efficient and valid model for JD challenge studies. None of the experimental or control vaccines evaluated prevented MAP infection or eliminated fecal shedding, although the 329 vaccine lowered the incidence of infection, fecal shedding, tissue colonization and reduced lesion scores, but less than the control vaccine. Based on our results the relative performance ranking of the experimental live-attenuated vaccines evaluated, the 329 vaccine was the best performer, followed by the 318 vaccine, then 316 vaccine, 315 vaccine and finally the 319 vaccine was the worst performer. The subcutaneously injected control vaccine outperformed the orally-delivered mutant vaccine candidates. Two vaccines (329 and 318) do reduce presence of JD gross and microscopic lesions, slow progression of disease, and one vaccine (329) reduced fecal shedding and tissue colonization.

AB Total parenteral nutrition (TPN) is associated with the development of parenteral nutrition-associated liver disease (PNALD) in infants. Fish oil-based lipid emulsions can reverse PNALD, yet it is unknown if they can prevent PNALD. We studied preterm pigs administered TPN for 14 days with either 100% soybean oil (IL), 100% fish oil (OV), or a mixture of soybean oil, medium chain triglycerides (MCTs), olive oil, and fish oil (SL); a group was fed formula enterally (ENT). In TPN-fed pigs, serum direct bilirubin, gamma glutamyl transferase (GGT), and plasma bile acids increased after the 14 day treatment but were highest in IL pigs. All TPN pigs had suppressed hepatic expression of farnesoid X receptor (FXR), cholesterol 7-hydroxylase (CYP7A1), and plasma 7 alpha-hydroxy-4-cholesten-3-one (C4) concentrations, yet hepatic CYP7A1 protein abundance was increased only in the IL versus ENT group. Organic solute transporter alpha (OST alpha) gene expression was the highest in the IL group and paralleled plasma bile acid levels. In cultured hepatocytes, bile acid-induced bile salt export pump (BSEP) expression was inhibited by phytosterol treatment. We show that TPN-fed pigs given soybean oil developed cholestasis and steatosis that was prevented with both OV and SL emulsions.(jlr) Due to the presence of phytosterols in the SL emulsion, the differences in cholestasis and liver injury among lipid emulsion groups in vivo were weakly correlated with plasma and hepatic phytosterol content.

AB Stored non-structural carbohydrates (NSCs) could play an important role in tree survival in the face of a changing climate and associated stress-related mortality. We explored the effects of the stomata-blocking and defoliating fungal disease called Swiss needle cast on Douglas-fir carbohydrate reserves and growth to evaluate the extent to which NSCs can be mobilized under natural conditions of low water stress and restricted carbon supply in relation to potential demands for growth. We analyzed the concentrations of starch, sucrose, glucose and fructose in foliage, twig wood and trunk sapwood of 15 co-occurring Douglas-fir trees expressing a gradient of Swiss needle cast symptom severity quantified as previous-year functional foliage mass. Growth (mean basal area increment, BAI) decreased by similar to 80% and trunk NSC concentration decreased by 60% with decreasing functional foliage mass. The ratio of relative changes in NSC concentration and BAI, an index of the relative priority of storage versus growth, more than doubled with increasing disease severity. In contrast, twig and foliage NSC concentrations remained nearly constant with decreasing functional foliage mass. These results suggest that under disease-induced reductions in carbon supply, Douglas-fir trees retain NSCs (either actively or due to sequestration) at the expense of trunk radial growth. The crown retains the highest concentrations of NSC, presumably to maintain foliage growth and shoot extension in the spring, partially compensating for rapid foliage loss in the summer and fall.

AB Thresholds in response by cavity-nesting bird populations to variations in the snag resource are poorly understood. In addition, limited information exists on the value of artificially created snags for cavitynesting birds. Therefore, uncertainty exists in whether artificially created snags can yield a positive population response among snag-dependent birds. We used an experimental approach to assess the abundance and territory dynamics of a primary cavity nester, the red-headed woodpecker (Melanerpes erythrocephalus), in response to three snag density treatments over an 8-year period following treatment installation in 2001. Treatments included snag removal, an unmanipulated control, and a snag pulse (snags experimentally created at 14 times control density). During the first two years post-treatment, abundance of red-headed woodpeckers did not differ among treatments. In 2004, woodpecker abundance in snag pulse plots surpassed that of other treatments and continued to increase until it peaked in 2007 (at nearly 6 times than on control plots), after which it declined but remained greater than on control plots through 2009. Increased woodpecker abundance in high snag density areas was facilitated primarily by a decrease in home range size. Because the red-headed woodpecker is negatively affected by very low snag densities, yet is capable of exploiting pulses in the snag resource by dramatically increasing its abundance, we conclude that snag density regulates populations of this primary cavity nesting species and that snag creation can be an important tool in its conservation.

AB The invasive thistle Carduus nutans has been reported to be allelopathic, yet no allelochemicals have been identified from the species. In a search for allelochemicals from C. nutans and the closely related invasive species C. acanthoides, bioassay-guided fractionation of roots and leaves of each species were conducted. Only dichloromethane extracts of the roots of both species contained a phytotoxin (aplotaxene, (Z,Z,Z)-heptadeca-1,8,11,14-tetraene) with sufficient total activity to potentially act as an allelochemical. Aplotaxene made up 0.44 % of the weight of greenhouse-grown C. acanthoides roots (ca. 20 mM in the plant) and was not found in leaves of either species. It inhibited growth of lettuce 50%(I-50) in soil at a concentration of ca. 0.5 mg g(-1) of dry soil (ca. 6.5 mM in soil moisture). These values gave a total activity in soil value (molar concentration in the plant divided by the molarity required for 50 % growth inhibition in soil = 3.08) similar to those of some established allelochemicals. The aplotaxene I-50 for duckweed (Lemna paucicostata) in nutrient solution was less than 0.333 mM, and the compound caused cellular leakage of cucumber cotyledon discs in darkness and light at similar concentrations. Soil in which C. acanthoides had grown contained aplotaxene at a lower concentration than necessary for biological activity in our short-term soil bioassays, but these levels might have activity over longer periods of time and might be an underestimate of concentrations in undisturbed and/or rhizosphere soil.

AB Differential plant use by herbivores has been observed for several woody plant species and has frequently been attributed to plant secondary metabolites. We examined the relationship between terpenoid concentration and Juniperus monosperma herbivory by small ruminants. Two groups of animals (10 goats or 5 goats plus 4 sheep) browsed 16 paddocks (20x30 m) containing one-seed juniper for six days during two seasons. Juniper leaves were sampled from 311 saplings immediately after browsing. Saplings were categorized by size (short [<0.5 m], medium [0.5-1.0 m], or tall [>1.0 m]), and by browsing intensity (light [<33%], moderate [33-66%], or heavy [>66%]). Juniper bark was collected from 12 saplings during spring. Total estimated terpenoid concentrations in leaves and bark were 18.3+/-0.3 and 8.9+/-0.8 mg/g, respectively, and the dominant terpene in both tissues was a-pinene (11.1+/-0.2 and 7.6+/-0.7 mg/g, respectively). Total terpenoid concentration of juniper leaves was greater in spring than summer (20.6+/-0.5 vs. 16.7+/-0.3 mg/g, respectively) and was lower in short saplings than medium or tall saplings (16.5+/-0.6 vs. 19.8+/-0.4 and 19.5+/-0.4 mg/g, respectively). Total terpenoid concentration of leaves also differed among the three defoliation categories (21.2+/-0.6, 18.7+/-0.5, and 16.1+/-0.4 mg/g for light, moderate, and heavy, respectively). The smallest subset of terpenoids able to discriminate between light and heavy browsing intensity categories included eight compounds ([E]-beta-farnesene, bornyl acetate, gamma-eudesmol, endo-fenchyl acetate, gamma-cadinene, a-pinene, cis-piperitol, and cis-p-menth-2-en-1-ol). Our results suggest terpenoid concentrations in one-seed juniper are related to season, sapling size, and browsing by small ruminants.

AB BACKGROUND AND OBJECTIVE:Previous studies of survivors of pediatric acute lymphoblastic leukemia (ALL) have drawn heterogeneous conclusions regarding the prevalence of obesity and risk factors for developing obesity in pediatric ALL survivors. We sought to determine the prevalence of obesity in pediatric ALL survivors and examine risk factors for obesity through a systematic review and meta-analysis.METHODS:A MEDLINE search was performed from its inception through 2013. Studies met the inclusion criteria if they (1) included at least 10 survivors of pediatric ALL; (2) assessed the prevalence or indicators of obesity; and (3) compared obesity among ALL survivors to a reference population or external control group. Extracted data included patient and treatment characteristics, study design, population used for comparison, and prevalence of obesity.RESULTS:Forty-seven studies met the inclusion criteria. Despite significant heterogeneity among the studies (I-2 = 96%), the mean BMI z score in 1742 pediatric ALL survivors was 0.83 (95% confidence interval: 0.60-1.06), which corresponds to the 80th BMI percentile, indicating a significantly higher BMI in pediatric ALL survivors than the reference population. Subgroup analyses found a high prevalence of obesity in ALL survivors regardless of survivors' receipt of cranial irradiation, gender, or age at diagnosis.CONCLUSIONS:Obesity is prevalent in pediatric ALL survivors and is independent of patient- and treatment-related characteristics. Clinicians need to screen for obesity and its associated health conditions early in survivorship.

PERSPECTIVE
AB The role of abiotic processes on dissolved organic matter (DOM) production is often underappreciated. However, abiotic processes appear to be especially important in subsoils where, with increasing depth, microbial activity declines and soil organic matter (SOM) becomes a progressively more important' contributor to DOM. Within three soil depths (20, 40, and 60 cm) in a temperate forest, soil temperature was positively associated with dissolved organic carbon (DOC) concentration (R-2 = 0.23-0.77) and the DOM humification index (R-2 = 0.35-0.72) for soil solutions in slow and fast flowpaths. With increasing soil temperature from 5 to 24 degrees C, average DOC concentrations increased by 86% at 20 cm, 12% at 40 cm and 12% at 60 cm soil depths. Our data suggest that DOM supply, especially in subsoils, is temperature dependent. We attribute this to the influence of temperature on DOM replenishment through direct processes such as SOM dissolution, diffusion and exchange reactions as well as indirect processes such as rhizodeposition and exoenzyme activity. In contrast, negative relationships (R-2 = 0.71-0.88) between temperature and nitrate concentrations in subsoil suggested that the temperature-dependent supply of DOM drives microbial processes such as dissimilatory and assimilatory nitrate consumption.

AB We present a two-layer hidden Markov model to detect the structure of haplotypes for unrelated individuals. This allows us to model two scales of linkage disequilibrium (one within a group of haplotypes and one between groups), thereby taking advantage of rich haplotype information to infer local ancestry of admixed individuals. Our method outperforms competing state-of-the-art methods, particularly for regions of small ancestral track lengths. Applying our method to Mexican samples in HapMap3, we found two regions on chromosomes 6 and 8 that show significant departure of local ancestry from the genome-wide average.

AB An Observing System Simulation Experiment (OSSE) for the Aquarius/SAC-D mission that includes different models for forward and retrieval processes is presented. This OSSE is implemented to study the errors related to the use of simple retrieval models in passive microwave applications. To this end, a theoretical forward model was introduced, which is suitable to reproduce some of the complexities related to canopy vegetation scattering. So far, this OSSE has been successfully exploited to study the artifacts in the retrieved soil moisture associated to: 1) uncertainties and aggregation of the ancillary parameters needed for the retrieval, and 2) instrumental noise effects. In this paper, we attempt to model the influence of this "model asymmetry" (different forward and inverse model) in the estimated soil moisture. These asymmetries are related to the fact that the emissivity of real surfaces is complex and strongly dependent on land cover type and condition. In particular, surface covered by average to dense vegetation presents complex scattering properties, related to canopy structure. Using this theoretical model, the difficulties related to retrieving soil moisture from passive data with a simple model are studied. The accuracy of the soil moisture estimation is analyzed in order to illustrate the impact of discrepancies between both models. In general, retrieved soil moisture performs worse over dense vegetated areas and under wet conditions. Furthermore, accuracy is highly dependent on land cover.

DE wood system reliability; modulus of rupture; modulus of elasticity;

AB Two important wood properties are the modulus of elasticity (MOE) and the modulus of rupture (MOR). In the past, the statistical distribution of the MOE has often been modeled as Gaussian, and that of the MOR as lognormal or as a two-or three-parameter Weibull distribution. It is well known that MOE and MOR are positively correlated. To model the simultaneous behavior of MOE and MOR for the purposes of wood system reliability calculations, we introduce a bivariate Gaussian-Weibull distribution and the associated univariate pseudo-truncated Weibull (PTW). We note that theoretical arguments suggest that the strength distributions of grades of lumber are likely to be PTW rather than Weibull. We describe a Web-based program that fits bivariate Gaussian-Weibull data sets (and thus fits PTW distributions to MOR data). We present data that demonstrate that strength distributions of visual grades of lumber are not Weibull and do display at least some of the characteristics of PTW data. Finally, we demonstrate via simulation that if we fit a Weibull distribution to PTW data (as is often done), we can obtain very poor estimates of probabilities of failure.

AB Nomenclatural rule changes in the International Code of Nomenclature for algae, fungi and plants, adopted at the 18th International Botanical Congress in Melbourne, Australia, in 2011, provide for a single name to be used for each fungal species. The anamorphs of Epichloe species have been classified in genus Neotyphodium, the form genus that also includes most asexual Epichloe descendants. A nomenclatural realignment of this monophyletic group into one genus would enhance a broader understanding of the relationships and common features of these grass endophytes. Based on the principle of priority of publication we propose to classify all members of this clade in the genus Epichloe: We have reexamined classification of several described Epichloe and Neotyphodium species and varieties and propose new combinations and states. In this treatment we have accepted 43 unique taxa in Epichloe including distinct species, subspecies, and varieties. We exclude from Epichloe the two taxa Neotyphodium starrii, as nomen dubium, and Neotyphodium chilense, as an unrelated taxon.

AB Veloporphyrellus is a genus known from North and Central America, southeastern Asia, and Africa. Because species of this genus are phenotypically similar to some taxa in several genera, such as Boletellus, Leccinum, Strobilomyces, Suillus and Tylopilus s.l. belonging to Boletales, its phylogenetic disposition has never been addressed. We analyzed four DNA regions, the nuclear ribosomal LSU and tef-1 alpha, and the mitochondrial mtSSU and atp6 genes, to investigate the phylogenetic disposition of Veloporphyrellus. Although the monophyly of the genus and its systematic placement within the Boletaceae was well supported, its relationship to other genera was not resolved. Morphologically Veloporphyrellus is distinguished from other boletoid genera by the combination of the pinkish or grayish pink hyrnenophore, the membranous veil hanging on the pilea margin, the trichoderm-like pileus covering and the smooth basidiospores. Five species, including two new species and two new combinations, are described and illustrated. A key to the species of Veloporphyrellus also is provided.

TI Split-replicates correlation of water content in cotton
SO TEXTILE RESEARCH JOURNAL
LA English
DT Article
DE cotton; Karl Fischer Titration; moisture equilibrium; split-replicates
correlation; water content
AB The range of water content in US cottons equilibrated to moisture equilibrium at standard textile testing conditions and analyzed by standard Karl Fischer Titration is small, <0.8%. This presents a challenge in obtaining accurate test data to calibrate fast sensors. A dozen raw cottons, nine American and three international, were analyzed for water by standard Karl Fischer Titration. The number of replicates analyzed, blending, and two conditioning systems - either standard room or closed chamber in the standard room with salt solution to control humidity - were examined. Split-replicates correlation within samples, by splitting out either half the available number or three replicates at a time, was used as the measure of correlation. The split-correlation results depended on the number of replicates, mixing of the laboratory sample, and method of conditioning. These results suggest that good correlations are possible when mean water content is the dependent variable in regressions with fast sensor data. This improved understanding of the correlation behavior, which is important for optimal application of methods to measure water in samples equilibrated to moisture equilibrium.

EVAPOTRANSPIRATION
AB Land use practices have caused stream channel incision and water table decline in many montane meadows of the Western United States. Incision changes the magnitude and timing of streamflow in water supply source watersheds, a concern to resource managers and downstream water users. The hydrology of montane meadows under natural and incised conditions was investigated using watershed simulation for a range of hydrologic conditions. The results illustrate the interdependence between: watershed and meadow hydrology; bedrock and meadow aquifers; and surface and groundwater flow through the meadow for the modeled scenarios. During the wet season, stream incision resulted in less overland flow and interflow and more meadow recharge causing a net decrease in streamflow and increase in groundwater storage relative to natural meadow conditions. During the dry season, incision resulted in less meadow evapotranspiration and more groundwater discharge to the stream causing a net increase in streamflow and a decrease in groundwater storage relative to natural meadow conditions. In general, for a given meadow setting, the magnitude of change in summer streamflow and long-term change in watershed groundwater storage due to incision will depend on the combined effect of: reduced evapotranspiration in the eroded meadow; induced groundwater recharge; replenishment of dry season groundwater storage depletion in meadow and bedrock aquifers by precipitation during wet years; and groundwater storage depletion that is not replenished by precipitation during wet years.
Key Points
Meadow and watershed properties influence meadow response to stream channel incision Postincision streamflow change is influenced by changes in the groundwater system Postincision streamflow change is sensitive to change in evapotranspiration

AB Field edges, old fields, and other semi-natural habitats in agricultural landscapes support diverse plant communities that help sustain pollinators, predators, and other beneficial arthropods. These plant and arthropod communities may be at significant ecotoxicological risk from herbicides applied to nearby crop fields. Recent innovations in herbicide-resistant crop biotechnology may lead to major increases in the use of the herbicides dicamba and 2,4-D. These herbicides selectively affect broadleaf plants, and nontarget exposures may therefore lead to a net reduction in the functional diversity and floral resources provided by semi-natural habitats. In multi-year experiments at two sites (a field edge and an old field), we exposed replicated plots to low doses of dicamba designed to simulate herbicide drift and monitored changes in plant and arthropod communities. At the field edge site, we observed a significant decline in forb cover (but not floral resources) in plots treated at doses (similar to 1% of the field application rate) that are substantially lower than those that have been documented to affect plant communities in previous research. We also observed declines in three herbivorous pest species (pea aphids, spotted alfalfa aphid, and potato leaf hopper), increases in one pest species (clover root curculio), and increases in beneficial seed predators (crickets) associated with dicamba exposure. In contrast, at the old field site, drift-level doses did not affect plant community structure but reduced flowering of a key species (Monarda fistulosa). Variability across sites and taxonomic groups makes it difficult to offer general conclusions about the risks of dicamba drift to plant and arthropod biodiversity. Factors including the successional age of the plant community and water stress at the time of herbicide exposure likely explain the differing responses at the two sites to simulated drift.

AB Microbial decomposer C metabolism is considered a factor controlling soil C stability, a key regulator of global climate. The plant rhizosphere is now recognized as a crucial driver of soil C dynamics but specific mechanisms by which it can affect C processing are unclear. Climate change could affect microbial C metabolism via impacts on the plant rhizosphere. Using continuous C-13 labelling under controlled conditions that allowed us to quantify SOM derived-C in all pools and fluxes, we evaluated the microbial metabolism of soil C in the rhizosphere of a C4 native grass exposed to elevated CO2 and under variation in N concentrations in soil and in plant root C:N stoichiometry. Our results demonstrated that this plant can influence soil C metabolism and further, that elevated CO2 conditions can alter this role by increasing microbial C efficiency as indicated by a reduction in soil-derived C respiration per unit of soil C-derived microbial biomass. Moreover, under elevated CO2 increases in soil N, and notably, root tissue N concentration increased C efficiency, suggesting elevated CO2 shifted the stoichiometric balance so N availability was a more critical factor regulating efficiency than under ambient conditions. The root C:N stoichiometry effect indicates that plant chemical traits such as root N concentration are able to influence the metabolism of soil C and that elevated CO2 conditions can modulate this role. Increased efficiency in soil C use was associated with negative rhizosphere priming and we hypothesize that the widely observed phenomenon of rhizosphere priming may result, at least in part, from changes in the metabolic efficiency of microbial populations. Observed changes in the microbial community support that shifting microbial populations were a contributing factor to the observed metabolic responses. Our case study points at greater efficiency of the SOM-degrading populations in a high CO2, high N world, potentially leading to greater C storage of microbially assimilated C in soil.

AB The optima conditions of production and purification of xylooligosaccharides (XOS) from Miscanthus x giganteus (MxG) were investigated. Using autohydrolysis, XOS were produced at 160, 180 and 200 degrees C at 60, 20 and 5 min, respectively. XOS yield up to 13.5% (w/w) of initial biomass and 69.2% (w/w) of xylan were achieved. Results from HPAEC-PAD analysis revealed that X1-X9 sugar oligomers were produced. Higher temperature and longer reaction time resulted in lower product molecular weight. The three optimum conditions had similar degrees of polymerization XOS. Using 10% activated carbon (w/v) with ethanol/water elution recovered 47.9% (w/w) of XOS from pretreated liquid phase. The XOS could be fractionated by degree of polymerization according to ethanol concentration in the ethanol/water elution. Most of the XOS were washed out in 30% and 50% ethanol/water (v/v) fractions. Recoveries of 91.8% xylobiose, 86.9% xylotriose, 66.3% xylotetrose, 56.2% xylopentose and 48.9% xylohexaose were observed in XOS. (C) 2014 Elsevier Ltd. All rights reserved.

AB Background Coronary heart disease (CHD) is the leading cause of death in diabetic women. In addition to hyperglycemia, other factors may contribute to the excessive cardiovascular risk.
Aim In this study we evaluated common and emerging risk factors in a selected group of postmenopausal type 2 diabetic women with (n = 36) and without CHD (n = 59), not taking lipid-lowering medications.
Methods Clinical and lifestyle data were collected, and metabolic and lipid profile, as well as fasting plasma levels of total homocysteine (tHcy), folate, vitamin B12, C-reactive protein (hsCRP), interleukin 6 (IL-6), and vascular cell adhesion molecule-1 (VCAM-1) were measured in all participants.
Results Age, menopause and diabetes duration, family history for cardiovascular disease, prevalence of hypertension and current insulin use were greater in diabetic women with than without CHD (P < 0.05 for all comparisons). CHD women also showed higher levels of triglycerides, small dense LDL (sdLDL), remnant-like particle cholesterol, tHcy, and VCAM-1, and a lower creatinine clearance (P < 0.05 all). Conversely, the two groups were comparable for BMI, waist circumference, smoking habit, fasting plasma glucose, HbA(1c), total cholesterol, low-density lipoprotein cholesterol (LDL-C), HDL cholesterol, folate, vitamin B12, hsCRP and IL-6 levels. At multivariate analysis, lower creatinine clearance (OR = 0.932, P = 0.017) and higher sdLDL serum concentration (OR = 1.224, P = 0.037) were the strongest risk factors associated with CHD in this population, whereas no significant association was noted with LDL-C.
Conclusions Our data suggest that beyond LDL-C, a lower creatinine clearance and more subtle alterations of LDL particles, together with a constellation of several well known and emerging cardiovascular risk factors, are stronger contributors to the high CHD risk of diabetic women.

AB Inventories of greenhouse gas (GHG) emissions from wildfire provide essential information to the state of California, USA, and other governments that have enacted emission reductions. Wildfires can release a substantial amount of GHGs and other compounds to the atmosphere, so recent increases in fire activity may be increasing GHG emissions. Quantifying wildfire emissions however can be difficult due to inherent variability in fuel loads and consumption and a lack of field data of fuel consumption by wildfire. We compare a unique set of fuel data collected immediately before and after six wildfires in coniferous forests of California to fuel consumption predictions of the first-order fire effects model (FOFEM), based on two different available fuel characterizations. We found strong regional differences in the performance of different fuel characterizations, with FOFEM overestimating the fuel consumption to a greater extent in the Klamath Mountains than in the Sierra Nevada. Inaccurate fuel load inputs caused the largest differences between predicted and observed fuel consumption. Fuel classifications tended to overestimate duff load and underestimate litter load, leading to differences in predicted emissions for some pollutants. When considering total ground and surface fuels, modeled consumption was fairly accurate on average, although the range of error in estimates of plot level consumption was very large. These results highlight the importance of fuel load input to the accuracy of modeled fuel consumption and GHG emissions from wildfires in coniferous forests.
Key Points
Measured fuel load immediately before and after six wildfires Compared observed consumption to predicted for several fuel classifications Inaccurate fuel load predictions led to error in estimates of consumption

AB Fire is a critical component of the Earth system, and substantially influences land surface, climate change, and ecosystem dynamics. To accurately predict the fire regimes in the 21st century, it is essential to understand the historical fire patterns and recognize the interaction among fire, human, and environment factors. Until now, few efforts are put on the studies regarding to the long-term fire reconstruction and the attribution analysis of anthropogenic and environmental factors to fire regimes at global scale. To fill this knowledge gap, we developed a 0.5 degrees x0.5 degrees data set of global burned area from 1901 to 2007 by coupling Global Fire Emission Database version 3 with a process-based fire model and conducted factorial simulation experiments to evaluate the impacts of human, climate, and atmospheric components. The average global burned area is similar to 442x10(4)km(2)yr(-1) during 1901-2007 and our results suggest a notable declining rate of burned area globally (1.28x10(4)km(2)yr(-1)). Burned area in tropics and extratropics exhibited a significant declining trend, with no significant trend detected at high latitudes. Factorial experiments indicated that human activities were the dominant factor in determining the declining trend of burned area in tropics and extratropics, and climate variation was the primary factor controlling the decadal variation of burned area at high latitudes. Elevated CO2 and nitrogen deposition enhanced burned area in tropics and southern extratropics but suppressed fire occurrence at high latitudes. Rising temperature and frequent droughts are becoming increasingly important and expected to increase wildfire activity in many regions of the world.
Key Points
Global burned area data set was reconstructed by using fire model simulation Global burned area showed a downward trend in the twentieth century Human and environmental factors were critical in shaping fire regimes

AB New remote sensing technologies and improved computer performance now allow numerical flow modeling over large stream domains. However, there has been limited testing of whether channel topography can be remotely mapped with accuracy necessary for such modeling. We assessed the ability of the Experimental Advanced Airborne Research Lidar, to support a multi-dimensional fluid dynamics model of a small mountain stream. Random point elevation errors were introduced into the lidar point cloud, and predictions of water surface elevation, velocity, bed shear stress, and bed mobility were compared to those made without the point errors. We also compared flow model predictions using the lidar bathymetry with those made using a total station channel field survey. Lidar errors caused <1cm changes in the modeled water surface elevations. Effects of the point errors on other flow characteristics varied with both the magnitude of error and the local spatial density of lidar data. Shear stress errors were greatest where flow was naturally shallow and fast, and lidar errors caused the greatest changes in flow cross-sectional area. The majority of the stress errors were less than 5Pa. At near bankfull flow, the predicted mobility state of the median grain size changed over 1.3% of the model domain as a result of lidar elevation errors and 3% changed mobility in the comparison of lidar and ground-surveyed topography. In this riverscape, results suggest that an airborne bathymetric lidar can map channel topography with sufficient accuracy to support a numerical flow model.

AB Identification of resistance to reniform nematode (Rotylenchulus reniformis) is the first step in developing resistant soybean (Glycine max) cultivars that will benefit growers in the mid-South region of the United States. This study was conducted to identify soybean (G. max and G. soja) lines with resistance to this pathogen. Sixty-one wild and domestic soybean lines were evaluated in replicated growth chamber tests. Six previously untested soybean lines with useful levels of resistance to reniform nematode were identified in both initial screening and subsequent confirmation tests: released germplasm lines DS4-SCN05 (PI 656647) and DS-880 (PI 659348); accession PI 567516 C; and breeding lines DS97-84-1, 02011-126-1-1-2-1 and 02011-126-1-1-5-1. Eleven previously untested moderately susceptible or susceptible lines were also identified: released germplasm lines D68-0099 (PI 573285) and LG015087-5; accessions PI 200538, PI 416937, PI 423941, PI 437697, PI 467312, PI 468916, PI 594692, and PI 603751 A; and cultivar Stafford (PI 508269). Results of previously tested lines evaluated in the current study agreed with published reports 69.6% of the time for resistant lines and 87.5% of the time for susceptible lines. Soybean breeders may benefit from incorporating the newly identified resistant lines into their breeding programs.

AB Under laboratory conditions, the biocontrol potential of Steinernema thermophilum was tested against eggs and larval stages of two important lepidopteran insect pests, Helicoverpa armigera and Spodoptera litura (polyphagous pests), as well as Galleria mellonella (used as a model host). In terms of host susceptibility of lepidopteran larvae to S. thermophilum, based on the LC50 36 hr after treatment, G. mellonella (LC50 = 16.28 IJ/larva) was found to be more susceptible than S. litura (LC50 = 85 IJ/larva), whereas neither host was found to be significantly different from H. armigera (LC50 = 54.68 IJ/larva). In addition to virulence to the larval stages, ovicidal activity up to 84% was observed at 200 IJ/50 and 100 eggs of H. armigera and S. litura, respectively. To our knowledge this is the first report of entomopathogenic nematode pathogenicity to lepidopteran eggs. Production of infective juvenile (IJ) nematodes/insect larva was also measured and found to be positively correlated with rate of IJ for H. armigera (r = 0.990), S. litura (r = 0.892), as well as G. mellonella (r = 0.834). Both Phase I and Phase II of symbiotic bacteria Xenorhabdus indica were tested separately against neonates of H. armigera and S. litura by feeding assays and found to be virulent to the target pests; phase variation did not affect the level of virulence. Thus S. thermophilum as well as the nematode's symbiotic bacteria applied separately have the potential to be developed as biocontrol agents for key lepidopteran pests.

AB The ability of entomopathogenic nematodes to tolerate environmental stress such as desiccating or freezing conditions, can contribute significantly to biocontrol efficacy. Thus, in selecting which nematode to use in a particular biocontrol program, it is important to be able to predict which strain or species to use in target areas where environmental stress is expected. Our objectives were to (i) compare inter-and intraspecific variation in freeze and desiccation tolerance among a broad array of entomopathogenic nematodes, and (ii) determine if freeze and desiccation tolerance are correlated. In laboratory studies we compared nematodes at two levels of relative humidity (RH) (97% and 85%) and exposure periods (24 and 48 h), and nematodes were exposed to freezing temperatures (-2 degrees C) for 6 or 24 h. To assess interspecific variation, we compared ten species including seven that are of current or recent commercial interest: Heterorhabditis bacteriophora (VS), H. floridensis, H. georgiana, (Kesha), H. indica (HOM1), H. megidis (UK211), Steinernema carpocapsae (All), S. feltiae (SN), S. glaseri (VS), S. rarum (17C&E), and S. riobrave (355). To assess intraspecific variation we compared five strains of H. bacteriophora (Baine, Fl1-1, Hb, Oswego, and VS) and four strains of S. carpocapsae (All, Cxrd, DD136, and Sal), and S. riobrave (355, 38b, 7-12, and TP). S. carpocapsae exhibited the highest level of desiccation tolerance among species followed by S. feltiae and S. rarum; the heterorhabditid species exhibited the least desiccation tolerance and S. riobrave and S. glaseri were intermediate. No intraspecific variation was observed in desiccation tolerance; S. carpocapsae strains showed higher tolerance than all H. bacteriophora or S. riobrave strains yet there was no difference detected within species. In interspecies comparisons, poor freeze tolerance was observed in H. indica, and S. glaseri, S. rarum, and S. riobrave whereas H. georgiana and S. feltiae exhibited the highest freeze tolerance, particularly in the 24-h exposure period. Unlike desiccation tolerance, substantial intraspecies variation in freeze tolerance was observed among H. bacteriophora and S. riobrave strains, yet within species variation was not detected among S. carpocapsae strains. Correlation analysis did not detect a relationship between freezing and desiccation tolerance.

AB Forest inventory studies in the Amazon indicate a large terrestrial carbon sink. However, field plots may fail to represent forest mortality processes at landscape-scales of tropical forests. Here we characterize the frequency distribution of disturbance events in natural forests from 0.01 ha to 2,651 ha size throughout Amazonia using a novel combination of forest inventory, airborne lidar and satellite remote sensing data. We find that small-scale mortality events are responsible for aboveground biomass losses of similar to 1.7 Pg Cy-1 over the entire Amazon region. We also find that intermediate-scale disturbances account for losses of similar to 0.2 Pg Cy-1, and that the largest-scale disturbances as a result of blow-downs only account for losses of similar to 0.004 Pg Cy-1. Simulation of growth and mortality indicates that even when all carbon losses from intermediate and large-scale disturbances are considered, these are outweighed by the net biomass accumulation by tree growth, supporting the inference of an Amazon carbon sink.

AB Insect sulfakinin receptors (SKRs) are G-protein-coupled receptors (GPCRs) that interact with sulfakinins (SKs) to modulate diverse biological processes. One of the indispensable roles of SKs is in the regulation of food intake in insects. In this project we report on the development of a cell-based receptor assay system with insect Sf9 cells, expressing TcSKR1 and TcSKR2 from the red flour beetle Tribolium castaneum, a model and important pest insect in agriculture. In this system, a stable presence of the two TcSKRs was supported by Western blotting. The expressed TcSKRs were coupled to Gas-protein upon activation and stimulated cAMP accumulation in Sf9 cells. Exposure of the transfected cell lines to sulfated SK ( sSK) activated TcSKR1 at 1 nM; the EC50 of sSK to obtain 50% of receptor activation was similar for both receptors. In contrast, p,M concentrations of non-sulfated SK were necessary to activate both TcSKRs. In conclusion, this cell-based TcSKR assay system is useful to screen SK-related peptides and mimetics and to better document ligand-receptor structure-activity relationships. Given the importance of SK signaling system in insects, the present study may provide new insights on the development of new methods to control pest insects. (c) 2014 Elsevier Inc.

AB The diapause hormone (DH) in the heliothine moth has shown its activity in termination of pupal diapause, while the orthology in the silkworm is known to induce embryonic diapause. In the current study, we cloned the diapause hormone receptor from the corn earworm Helicoverpa zea (HzDHr) and tested its ligand specificities in a heterologous reporter system. HzDHr was expressed in Chinese Hamster Ovary (CHO) cells, which were co-transfected with the aequorin reporter, and was used to measure the ligand activities. A total of 68 chemicals, including natural DH analogs and structurally similar peptide mimetics, were tested for agonistic and antagonistic activities. Several peptide mimetics with a 2-amino7-bromofluorene-succinoyl (2Abf-Suc) N-terminal modification showed strong agonistic activities; these mimetics included 2Abf-Suc-F[dA]PRLamide, 2Abf-Suc-F[dR]PRLamide, 2Abf-Suc-FKPRLamide and 2Abf-Suc-FGPRLamide. Antagonistic activity was found in the ecdysis triggering hormone in Drosophila melanogaster (FFLKITKNVPRLamide). Interestingly, HzDHr does not discriminate between DH (WFGPRLamide C-terminal motif) and another closely related endogenous peptide, pyrokinin 1 (FXPRXamide; a C-terminal motif that is separate from WFGPRLamide). We provide large-scale in vitro data that serve as a reference for the development of agonists and antagonists to disrupt the DH signaling pathway. (c) 2013 Elsevier Inc. All rights reserved.

AB Comparing analytical results for Sulfite Pretreatment to Overcome the Recalcitrance of Lignocelluloses (SPORL) of Douglas-fir (Pseudotsuga menziesii) at two different temperatures shows that the apparent activation energy of sugar degradation is higher than that of hemicellulose hydrolysis, approximately 161 kJ/mole versus 100 kJ/mole. Thus, one can balance the production of degradation products against hemicellulose hydrolysis and therefore the enzymatic saccharification efficiency of the resultant substrate by changing pretreatment temperature and duration. Specifically, pretreatment at 165 degrees C for 75 min significantly reduced furan formation compared with the pretreatment at 180 degrees C for 30 min while maintaining the same pretreatment severity and therefore the same substrate enzymatic digestibility (SED). Obtaining high SED with Douglas-fir is also limited by lignin content. Fortunately, the bisulfite in SPORL provides delignification activity. By combining kinetic models for hemicelluloses hydrolysis, sugar degradation, and delignification, the performance of pretreatment can be optimized with respect to temperature, duration, acid, and bisulfite loading. The kinetic approach taken in this study is effective to design viable low temperature pretreatment processes for effective bioconversion of lignocelluloses. Published by Elsevier Ltd.

AB Satellite-inferred burn severity data have become increasingly popular over the last decade for management and research purposes. These data typically quantify spectral change between pre-and post-fire satellite images (usually Landsat). There is an active debate regarding which of the two main equations, the delta normalized burn ratio (dNBR) and its relativized form (RdNBR), is most suitable for quantifying burn severity; each has its critics. In this study, we propose and evaluate a new Landsat-based burn severity metric, the relativized burn ratio (RBR), that provides an alternative to dNBR and RdNBR. For 18 fires in the western US, we compared the performance of RBR to both dNBR and RdNBR by evaluating the agreement of these metrics with field-based burn severity measurements. Specifically, we evaluated (1) the correspondence between each metric and a continuous measure of burn severity (the composite burn index) and (2) the overall accuracy of each metric when classifying into discrete burn severity classes (i.e., unchanged, low, moderate, and high). Results indicate that RBR corresponds better to field-based measurements (average R-2 among 18 fires = 0.786) than both dNBR (R-2 = 0.761) and RdNBR (R-2 = 0.766). Furthermore, the overall classification accuracy achieved with RBR (average among 18 fires = 70.5%) was higher than both dNBR (68.4%) and RdNBR (69.2%). Consequently, we recommend RBR as a robust alternative to both dNBR and RdNBR for measuring and classifying burn severity.

AB Soil water evaporation is an important component of the water budget in cropped fields; few methods are available for continuous and independent measurement. A sensible heat balance (SHB) approach has been demonstrated for continuously determining soil water evaporation under bare surface conditions. Applicability of SHB measurements beneath a crop canopy cover has not been evaluated. We tested SHB using heat-pulse sensors to estimate evaporation beneath a full maize (Zea mays L.) canopy. We also implemented a modified SHB approach incorporating below-canopy net radiation, which extended the range of conditions under which SHB is applicable. Evaporation was measured at three positions: row (R), interrow (I), and interrow with roots excluded (IE). Evaporation rates were generally small, averaging < 0.7 mm d(-1) across all dates, positions, and measurement methods during the drying period. The SHB evaporation estimates varied among R, I, and IE, with cumulative totals of 4.4, 7.4, and 7.9 mm, respectively, during a 12-d drying period. Lower soil water contents from plant water uptake reduced evaporation rates at R more appreciably with time than at the other positions; I and IE provided similar evaporation patterns. The SHB evaporation estimates at R and I were compared with microlysimeter data on 8 d. Correlation between approaches was modest (r(2) = 0.61) but significant (p < 0.001) when compared separately at R and I positions. Correlation was improved (r(2) = 0.81) when evaporation estimates were combined across positions, with differences between SHB and microlysimeters typically within the range of values obtained from microlysimeter replicates. Overall, the results suggest good potential for using SHB and modified SHB approaches to determine soil water evaporation in a cropped field. The SHB approach allowed continuous daily estimates of evaporation, separate from evapotranspiration and without destructive sampling.

AB Selenite Se(IV) and selenate Se(VI) adsorption behavior was investigated on gibbsite as a function of solution pH and solution ionic strength. Adsorption of both Se redox states decreased with increasing solution pH. Electrophoretic mobility measurements showed downward shifts in point of zero charge (PZC) indicative of the formation of inner-sphere Se(IV) and Se(VI) surface complexes. However, the downward shift was less than for strongly adsorbing anions such as phosphate and arsenate, suggesting that outer-sphere surface complexes are also present. The triple layer model, a chemical surface complexation model, was well able to describe Se(IV) and Se(VI) adsorption as a function of solution pH and solution ionic strength by simultaneously optimizing both inner-sphere and outer-sphere surface complexation constants. Direct spectroscopic investigations of selenite surface configuration are needed to corroborate the species suggested by the macroscopic experiments and obtained from the triple layer model optimizations.

AB Boron soil tests currently in use, do not extract all available B but are used by relating the extractable amount of B to plant B content. There is a need to accurately measure all available or adsorbed B because B can be toxic to plants at elevated concentrations and can cause marked yield decrements. Determination of the adsorbed B pool in the soil is also required for evaluation of the extent of leaching needed when B levels in soil solution are excessive, as well as for modeling studies regarding B transport in soils. Sugar alcohols form strong bonds between their cis-diol groups and B and are therefore, ideal for use as extractants for soil B. We evaluated the extraction performance of various sugar alcohols: sorbitol, mannitol, xylitol, and varying soil/solution ratios (1-1000 g L-1) and reaction times (1-48 h). We selected sorbitol as the extractant, utilizing a soil/solution ratio of 100 g L-1, and reaction time of 24 h. This soil test was able to provide quantitative recovery of B added to a diverse set of seven soils from California, Iowa, and Oklahoma. Results from the new B soil test can be used to quantify adsorbed B and thus provide needed input to both chemical speciation-transport models such as UNSATCHEM to obtain accurate predictions of B transport and partitioning in soils, as well as allowing for improved management of waters and soils high in B.

AB Soils developed on relict hydrothermally altered soils throughout the Western USA present unique opportunities to study the role of geology on above and belowground biotic activity and composition. Soil and vegetation samples were taken at three unaltered andesite and three hydrothermally altered (acid-sulfate) sites located in and around Lassen VolcanicNational Park in northeastern California. In addition, three different types of disturbed areas (clearcut, thinned, and pipeline) were sampled in acid-sulfate altered sites. Soils were sampled (0-15 cm) in mid-summer 2010 from both under-canopy and between-canopy areas within each of the sites. Soils were analyzed for numerous physical and chemical properties along with soil enzyme assays, C and N mineralization potential, microbial biomass-C and C-substrate utilization. Field vegetation measurements consisted of canopy cover by life form (tree, shrub, forb, and grass), tree and shrub density, and aboveground net primary productivity of the understory. Overall, parameters at the clearcut sites were more similar to the unaltered sites, while parameters at the thinned and pipeline sites were more similar to the altered sites. We employed principal components analysis (PCA) to develop two soil quality indices (SQI) to help quantify the differences among the sites: one based on the correlation between soil parameters and canopy cover, and the second based on six sub-indices. Soil quality indices developed in these systems could provide a means for monitoring and identifying key relations between the vegetation, soils, and microorganisms.

AB Dimethyl disulfide (DMDS) is a soil fumigant used in agricultural systems as an alternative to methyl bromide (MeBr) for the control of soilborne pests and pathogens. However, fumigants including DMDS that have broad biocidal activity can affect both target and non-target organisms in soil. This study focused on the effects of DMDS on the recovery of ecologically important microbial communities and soil abiotic factors while affecting plant parasitic nematodes in both field and microplot trials. Phospholipid fatty acid (PLFA) analysis was used to characterize changes in microbial community structure over time. Total amount of PLFA as well as all major non-target soil microbial groups such as Gram positive bacteria, Gram negative bacteria, fungi, arbuscular mycorrhizal fungi (AMF), and actinomycetes decreased significantly 15 d after fumigation in the untreated control as well as in all the rates of DMDS tested in a microplot trial. Fumigation had little effect on microbial biomass but at some time points some treatments did affect microbial community structure. Canonical multivariate analysis of variance indicated that soil microbial communities 45, 60, and 90 d after fumigation were similar to one another compared with 15 d after fumigation. The research showed that reduction and changes in microbial community biomass and structure were mainly due to environmental factors and therefore, it is concluded that DMDS fumigation did not impact the activity of beneficial microorganisms. Total N, C, and other abiotic factors were also not affected by DMDS fumigation. Plant parasitic nematodes were greatly affected by DMDS fumigation and this interaction could be related to its mode of action which affects nematode mitochondrial activity.

AB Amending soils with biochar can sequester C and improve soil properties, such as nutrient holding capacity and water retention. While biochars generally have a long residence time in soil, the turnover of biochar C can be influenced by both biochar characteristics and soil properties. Biochar can also potentially alter the rate of decomposition of native soil organic matter (SOM). The turnover of switchgrass (Panicum virgatum L.)-derived biochar C was evaluated in the laboratory using soil from four marginally productive sites in central Pennsylvania. Carbon dioxide emissions from unamended soil, biochar-amended soil, and pure biochar were monitored during 189-d incubations, and data were fit to a two-pool exponential model to estimate the amount and mean residence time (MRT) of C in labile and stable pools. Carbon-13 signatures of emitted CO2 were also determined to estimate the proportion of emitted CO2 derived from the biochar. Mixing biochar with each of the soils reduced the apparent MRT of C in both labile and stable pools, but the magnitude of change depended on the soil. Overall, the biochar was largely stable in each soil, with only 1.1 to 2.1% of the added biochar C emitted during incubation. There was no measurable effect of biochar amendment on the turnover of native SOM in any of the soils. Therefore, we conclude that amendment of our soils with switchgrass-derived biochar can effectively increase net C sequestration.

AB Soils in the Kansas Cherokee Prairies have formed in various parent materials and exhibit differences in the degree of expression of vertic properties. Despite large clay contents, few soils meet the criteria for a Vertisol. In an effort to investigate the cause of these differences, pedogenic processes, primarily clay illuviation and shrink-swell processes, were evaluated in eight pedons. Relatively high coefficient of linear extensibility (COLE) values were found in all soils. The clay mineralogy of four sites was dominated by smectite, but only two of those sites classified as Vertisols. In the other four sites, smectite was the most common clay mineral, yet there were several other clay minerals present in significant quantities. Disruption of illuvial clay features by shrink-swell movement was evident in the thin sections of all soils. Striated b-fabrics dominated except in surface soils that exhibited a small COLE value and occurred above an argillic horizon. Linear planes lined with stress-oriented clay and representing zones of shear failure were observed, along with argillans that had been distorted and embedded within the matrix by swelling pressure and soil movement. In conclusion, when present, a nonexpansive silty surface layer acts as a buffer and may limit shrink-swell by allowing expansive subsoils to dry more slowly.

AB In semiarid climates, efficient precipitation capture and storage are necessary for successful small grain production.This is especially true in Mediterranean climates dependent on winter precipitation occurring before the most active growth and grain development stages of winter wheat (WW, Triticum aestivum L.).The effects of residue cover and tillage on soil water under annual WW were investigated at Pendleton, OR, on a Walla Walla silt loam soil, (coarse-silty, mixed, superactive, mesic Typic Haploxerolls).These effects were investigated using three treatments in annually cropped WW, (i.e., no fallow year), consisting of no-till (NT), crop residue incorporated with tillage (TI), and crop residue removed before tillage and then returned to the soil surface after tillage (RR).Field data showed that ground cover from crop residue resulted in more soil water from December 24 through May 20 in the driest crop year, 2005, of the 3-yr experiment, but no differences in the two relatively wet crop years 2004 and 2006.The mean soil water in a 105-cm profile when treatment differences occurred were as follows; NT = 187 mm, RR = 168 mm, and TI = 155 mm.The differences were relatively small, however, with NT 31.7 mm more than TI and 19.2 mm more than RR, and RR 12.5 mm more than TI.During normal years these differences could be expected to diminish.This research indicates that tillage practices in the Pacific Northwest have small effect where the land surface is essentially level, but ground cover can play an important role during exceptionally dry years on precipitation capture and storage.

AB Vegetation restoration probably has great effects on the process of soil detachment. This study was conducted to investigate the effects of near soil surface characteristics on soil detachment by overland flow in a 7-yr restored natural grassland. Four treatments were designed to characterize the effects of dead roots, live roots, biological soil crusts (BSCs), and plant litter-stems in succession. For comparison, an undisturbed bare Loess soil was used as a baseline. The testing area (1.0 m in length and 0.1 m in width) of each treatment was subjected to flow scouring under five different shear stresses ranging from 6 to 13 Pa. The results showed that near soil surface properties of plant litter-stem, BSCs, and plant roots enhanced the resistance of soil to water detachment significantly. With these factors subsequently superimposed, soil detachment capacity decreased progressively. Taken together, the 7-yr restored natural grassland would decrease soil detachment capacity by 98.9% compared with the bare Loess soil, in which plant litter-stem, BSCs, and total roots contributed to 30.3, 14.9, and 53.7%, respectively. Furthermore, for the total root effects, chemical bonding of root exudates accounted for 14.7% while physical binding of root systems accounted for 39.0%. Results also indicated that BSCs were unable to protect the soil from detachment when the shear stress was greater than 11 Pa, and tended to accelerate soil erosion. This paper developed an equation for adjusting WEPP's rill erodibility for use in natural succession grassland in the Loess Plateau of China, and the result seemed satisfactory with the Nash-Sutcliffe efficiency (NSE) coefficients ranging from 0.28 to 0.77. Further studies are needed to detect the dynamics of near soil surface characteristics with succession age of grassland in the Loess Plateau.

AB The substitution of forest-derived woody biofuels for fossil fuel energy has garnered increasing attention in recent years, but information regarding the mid- and long-term effects on soil productivity is limited. We investigated 15-yr temporal trends in forest floor and mineral soil (0-30 cm) C and N pools in response to organic matter removal treatments (OMR; stem-only harvest, SOH; whole-tree harvest, WTH; and whole-tree plus forest floor removal, FFR) at three edaphically distinct aspen (Populus tremuloides Michx. and P. grandidentata Michx.) forests in the Great Lakes region. The OMR and temporal effects were generally site specific, and both were most evident in the forest floor and combined profile (mineral soil and forest floor) compared with the mineral soil alone. Forest floor and combined profile C and N pools were generally similar in the SOH and WTH treatments, suggesting that slash retention has little impact on soil C and N in this time frame. Temporal changes in C and N at one of the three sites were consistent with patterns documented following exotic earthworm invasion, but mineral soil pools at the other two sites were stable over time. Power analyses demonstrated that significant effects were more likely to be detected for temporal differences than the effects of OMR and in the combined profile than in the mineral soil. Our findings are consistent with previous work demonstrating that OMR effects on soil C and N pools are site specific and more apparent in the forest floor than the mineral soil.

AB Secondary exposure of wildlife to pesticides has been well documented, yet exposure is typically associated with agricultural or wildland-urban interface areas. Wildlife in undeveloped areas is generally presumed free from risk. In 2009, a male fisher was found dead in the Sierra National Forest and subsequent necropsy revealed that the animal died of acute rodenticide poisoning. Follow-up testing revealed that 85% of fisher carcasses recovered by two research projects in the previous three years tested positive for rodenticides. Concern arose that exposure could predispose an animal to mortality from other causes, and that the underlying role of toxicants would escape notice. Further investigation indicated that the most likely source was the numerous illegal marijuana cultivation sites currently found on public lands throughout the western United States. To determine whether the presence of cultivation sites predisposed fishers to mortality from other sources, we related survival rates to the presence and number of cultivation sites found within that animal's home range over the past 10 years. Likelihood of exposure was related to the presence of cultivation sites, and female fisher survival was influenced by the number of cultivation sites within its home range. We discuss the conservation implications of this unexpected relationship.

TI Effectiveness of Landowner Assistance Activities: An Examination of the

ID WEST-VIRGINIA
AB The USDA Forest Service's Forest Stewardship Program (FSP) is the nation's most prominent private forestry assistance program. We examined the FSP using a multiple analytic approach: analysis of annual FSP accomplishments, survey of state FSP coordinators, analytic comparison of family forest owners receiving and not receiving forestry practice assistance, and focus groups with family forest owners. We found the FSP reaches a small fraction of eligible landowners; states use FSP funds to address local private forestland issues; landowners obtaining assistance commonly associated with the FSP (e.g., management plans) differ from others in sociodemographics, ownership objectives, and land management actions but not in terms of intent to sell/subdivide forestland; and traditional FSP activities are not influencing inactive family forest owners to become active managers. We believe current practices (e.g., state-level flexibility) help the FSP reach its goals, alternative assistance-related efforts may increase the reach of the FSP and support strategic goals, and data collection improvements may enrich future FSP evaluations.

AB Traditional ecological knowledge (TEK) has been proposed as a basis for enhanced understanding of ecological systems and their management. TEK also can contribute to targeted inventories of resources not included in standard mensuration. We discuss the results of a cooperative effort between the Great Lakes Indian Fish and Wildlife Commission (GLIFWC) and USDA Forest Service's Forest Inventory and Analysis Program (FIA). At the urging of member tribes, GLIFWC staff worked with tribal gatherers to document TEK regarding desired characteristics of birch bark for traditional uses and translated this into an inventory field guide. The guide was provided to FIA, which incorporated the methods into its field manual and trained inventory crews in implementation of the protocol. Birch bark data were collected during three field seasons from 2004 to 2006. Results show birch bark supply has declined. Lessons learned from this multiyear, multistage project provide a model for future targeted inventory efforts.

AB The ability of certain apple rootstocks to dwarf their scions has been known for centuries and their use revolutionized apple (Mains xdomestica) production systems. In this investigation, several apple rootstock breeding populations, planted in multiple replicated field and pot experiments, were used to ascertain the degree of dwarfing when grafted with multiple scions. A previous genetic map of a breeding population derived from parents 'Ottawa 3' (O.3) and 'Robusta 5' (R5) was used for quantitative trait locus (QTL) analysis of traits related to scion vigor suppression, induction of early bearing, and other tree size measurements on own-rooted and grafted trees. The analysis confirmed a previously reported QTL that imparts vigor control [Dw1, log of odds (LOD) = 7.2] on linkage group (LG) 5 and a new QTL named Dw2 (LOD = 6.4) on LG11 that has a similar effect on vigor. The data from this population were used to study the interaction of these two loci. To validate these findings, a new genetic map comprised of 1841 single-nucleotide polymorphisms was constructed from a cross of the dwarfing, precocious rootstocks 'Geneva 935' (G.935) and 'Budagovsky 9' (B.9), resulting in the confirmation and modeling of the effect of Dw1 and Dw2 on vigor control of apple scions. Flower density and fruit yield data allowed the identification of genetic factors Eb1 (LOD = 7.1) and Eb2 (LOD = 7.6) that cause early bearing of scions, roughly colocated with the dwarfing factors. The major QTL for mean number of fruit produced per tree colocated with Dw2 (LOD = 7.0) and a minor QTL was located on LG16 (LOD = 3.5). These findings will aid the deveLODment of a marker-assisted breeding strategy, and the discovery of additional sources for dwarfing and predictive modeling of new apple rootstocks in the Geneva (R) apple rootstock breeding program.

AB There are very few studies detailing the aroma, astringency, and flavor of rabbiteye blueberry [RAB (Vaccinium ashei)] fruit typically grown in the southeastern United States. The objectives were to investigate the rapid and qualitative solid-phase microextraction gas chromatographic mass spectrometry volatile composition of several local RAB cultivars with an overall goal to build a database of possible flavor and aroma compounds. Volatile profiles were obtained in five Louisiana-grown RAB cultivars (Brightwell, Climax, Premier, Powder Blue, and Tifblue) assayed at four maturities. The method routinely captured 53 volatiles, including 12 aldehydes, six alcohols, 11 esters, four ketones, 17 terpenoids, one furan, and two aromatics. Of the 33 compounds considered important in blueberries, 17 were recovered in the RAB cultivars assessed. Herein, 10 compounds were recovered for the first time in blueberry (Vaccinium sp.) and five of those compounds were confirmed with standards [2-ethylfuran, (E)-2-pentenal, (Z)-dehydroxylinalool oxide, (E)-dehydroxylinalool oxide and 1,4-cineole]. In general, terpenoids and their subclass linalools were the most significant volatiles followed closely by esters, aldehydes, and then alcohols. Terpenoids and linalools displayed the greatest significant differences in 'Powder Blue' and 'Premier'. Esters and aldehydes were the most significant compound classes based on cultivar effect per maturity in firm-ripe fruit. From the suite of 17 of the 33 important compounds in upright blueberry, 10 were recovered across the five cultivars at four maturities that displayed a high level of significance. These were linalool, methyl 3-methylbutanoate, 1,8-cineole, (E)-2-hexanal, (Z)-3-hexenal, (Z)-3-hexenyl acetate, limonene, hexyl acetate, hexanal, and alpha-terpineol. These data will be useful to evaluate aroma volatiles in RAB and changes in processed and value-added byproducts.

AB Circumlineatus (cl) in common bean (Phaseolus vulgaris L.) is identified by a precipitation line in the seedcoat at the boundary of the white and colored zones. Cl is recessive and is expressed in partly colored seedcoats (t) with restricted patterns such as virgarcus. In this study, amplified fragment length polymorphism (AFLP) and single nucleotide polymorphism (SNP) markers, and the common bean genome sequence were used in combination with bulk segregant analysis and bidirectional selective genotyping to identify the genetic location of Cl. Markers were identified that cosegregated with Cl using Cl/Cl and cl/cl F-3 and F-5 progeny bulks from the cross t z cl G b v virgarcus BC3 5-593 x t z(sel) Cl G b v sellatus BC3 5-593. Two bands from an AFLP primer combination, which yielded unambiguous polymorphisms between the bulks, were cloned and sequenced. The two sequences were used to interrogate the common bean whole genome sequence identifying a region also found through cosegregation analysis using bidirectional selective genotyping with SNPs. Thus, the Cl gene was localized on Pv09 using cosegregating AFLP and SNP markers, and the physical location was confirmed with the whole genome sequence.

AB Cacao (Theobroma cacao L.) is an important cash crop in tropical growing regions of the world and particularly for small cacao farmers. Over the past two decades, 'CCN 51' has become one of the most planted cultivars in Ecuador, mainly as a result of its high productivity and disease resistance. Intermixing of Nacional fine flavor Ecuadorian beans with beans of 'CCN 51' has become common practice, reducing overall bean quality and decreasing value. The primary goals of this study were to determine the genetic identity, structure, and allelic richness of 'CCN 51', its maternal origin and to compare 'CCN 51's' agronomic characteristics against a composite group of Nacional cultivars. To investigate the complex genetic background of this cultivar, 70 simple sequence repeat loci were used. The high heterozygosity observed (56 of 70 loci) for 'CCN 51' is not characteristic of traditional Nacional cultivars. Comparison of agronomic characteristics between 'CCN 51' and several Nacional cultivars indicates significant differences in cacao dry bean weight, yield potential, production efficiency, percent healthy pods, and witches' broom [Moniliophthora perniciosa (Stahel) Aime & Phillips-Mora] disease incidence. Additionally, physical, chemical, and organoleptic characteristics suggest that 'CCN 51' is different from those of Nacional lineage. Based on population structure analysis, the predominant ancestries for 'CCN 51' are Iquitos (45.4%), Criollo (22.2%), and Amelonado (21.5%) genetic groups. A lesser proportion of its genome was accounted for by genetic groups Contamana (3.9%), Purns (2.5%), Maranon (2.1%), and Nacional (1.1%) admixtures. Results of phylogenetic analyses using the unweighted pair group method with arithmetic mean yielding high bootstrap values strongly support the relatedness of 'CCN 51' with Iquitos, Criollo, and Amelonado genetic groups. Moreover, seven mitochondrial simple sequence repeat loci revealed that 'CCN 51' maternally inherited the 'IMC 67' cytotype. 'CCN 51' constitutes a valuable cacao genetic resource that is currently used not only in its country of origin, but also in many other national breeding and selection programs worldwide.

AB Salmonella is a leading cause of foodborne illness and can be transmitted through consumption of contaminated poultry; therefore, increasing a flock's natural resistance to Salmonella could improve food safety. Previously, we characterized the heterophil-mediated innate immune response of 2 parental broiler lines and F-1 reciprocal crosses and showed that increased heterophil function and expression of pro-inflammatory mediators corresponds with increased resistance against diverse pathogens. A preliminary selection trial showed that individual sires had varying inherent levels of pro-inflammatory mediators and selection based on a high or low phenotype was passed onto progeny. Based on these results, we hypothesized selection of broilers for higher levels of the pro-inflammatory mediators IL-6, CXCLi2, and CCLi2 would produce progeny with increased resistance against Salmonella Enteritidis. Peripheral blood leukocytes were isolated from 75 commercial broiler sires, screened, and 10 naturally high and low expressing sires were selected and mated to randomly selected dams to produce the first generation of "high" and "low" progeny. The mRNA expression of CXCLi2 and CCLi2 were significantly (P <= 0.02) higher in the high progeny and were more resistant to liver and spleen organ invasion by Salmonella Enteritidis compared with low progeny. Production of the second generation yielded progeny that had differences (P <= 0.03) in all 3 mediators and further improved resistance against Salmonella Enteritidis. Feed conversion ratio and percent breast meat yield were calculated and were equal, whereas the high birds weighed slightly, but significantly, less than the low birds. These data clearly demonstrate that selection based on a higher phenotype of key pro-inflammatory mediators is a novel means to produce broilers that are naturally more resistant to Salmonella, one of the most important foodborne pathogens affecting the poultry industry.

Chicken embryo fibroblast (CEF) cells from MD susceptible and resistant lines were infected either with Marek's disease virus (MDV) or treated with polyionosinic-polycytidylic acid, a synthetic analog of dsRNA, and the expression of TLR and pro-inflammatory cytokines was studied at 8 and 36 h posttreatment by quantitative reverse transcriptase PCR. Findings of the present study reveal that MDV infection and polyionosinic-polycytidylic acid treatment significantly elevated the mRNA expression of TLR3, IL6, and IL8 in both susceptible and resistant lines. Furthermore, basal expression levels in uninfected CEF for TLR3, TLR7, and IL8 genes were significantly higher in resistant chickens compared with those of susceptible chickens. Our results suggest that TLR3 together with pro-inflammatory cytokines may play a significant role in genetic resistance to MD.

AB Both epidemiologic analyses and active disease surveillance confirm an ongoing strong association between human salmonellosis and the prevalence of Salmonella enterica subspecies enterica serovar Enteritidis in commercial egg flocks. The majority of human illnesses caused by this pathogen are attributed to the consumption of contaminated eggs. Animal welfare concerns have increasingly influenced commercial poultry production practices in recent years, but the food safety implications of different housing systems for egg-laying hens are not definitively understood. The present study assessed the effects of 2 different housing systems (conventional cages and colony cages enriched with perching and nesting areas) on the frequency of Salmonella Enteritidis contamination inside eggs laid by experimentally infected laying hens. In each of 2 trials, groups of laying hens housed in each cage system were orally inoculated with doses of 1.0 x 10(8) cfu of Salmonella Enteritidis. All eggs laid between 5 and 25 d postinoculation were collected and cultured to detect internal contamination with Salmonella Enteritidis. For both trials combined, Salmonella Enteritidis was recovered from 3.97% of eggs laid by hens in conventional cages and 3.58% of eggs laid by hens in enriched cages. No significant differences (P > 0.05) in the frequency of egg contamination were observed between the 2 housing systems.

AB Biological invasions resulting from international trade can cause major environmental and economic impacts. Propagule pressure is perhaps the most important factor influencing establishment, although actual arrival rates of species are rarely recorded. Furthermore, the pool of potential invaders includes many species that vary in their arrival rate and establishment potential. Therefore, we stress that it is essential to consider the size and composition of species pools arriving from source regions when estimating probabilities of establishment and effects of pathway infestation rates. To address this, we developed a novel framework and modeling approach to enable prediction of future establishments in relation to changes in arrival rate across entire species pools. We utilized 13828 border interception records from the United States and New Zealand for 444 true bark beetle (Scolytinae) and longhorned beetle (Cerambycidae) species detected between 1949 and 2008 as proxies for arrival rates to model the relationship between arrival and establishment rates. Nonlinearity in this relationship implies that measures intended to reduce the unintended transport of potential invaders (such as phytosanitary treatments) must be highly effective in order to substantially reduce the rate of future invasions, particularly if trade volumes continue to increase.

AB A recurrent challenge in the conservation of wide-ranging, imperiled species is understanding which habitats to protect and whether we are capable of restoring degraded landscapes. For Greater Sage-grouse (Centrocercus urophasianus), a species of conservation concern in the western United States, we approached this problem by developing multi-scale empirical models of occupancy in 211 randomly located plots within a 40 million ha portion of the species' range. We then used these models to predict sage-grouse habitat quality at 826 plots associated with 101 post-wildfire seeding projects implemented from 1990 to 2003. We also compared conditions at restoration sites to published habitat guidelines. Sage-grouse occupancy was positively related to plot- and landscape-level dwarf sagebrush (Artemisia arbuscula, A. nova, A. tripartita) and big sagebrush steppe prevalence, and negatively associated with non-native plants and human development. The predicted probability of sage-grouse occupancy at treated plots was low on average (0.09) and not substantially different from burned areas that had not been treated. Restoration sites with quality habitat tended to occur at higher elevation locations with low annual temperatures, high spring precipitation, and high plant diversity. Of 313 plots seeded after fire, none met all sagebrush guidelines for breeding habitats, but approximately 50% met understory guidelines, particularly for perennial grasses. This pattern was similar for summer habitat. Less than 2% of treated plots met winter habitat guidelines. Restoration actions did not increase the probability of burned areas meeting most guideline criteria. The probability of meeting guidelines was influenced by a latitudinal gradient, climate, and topography. Our results suggest that sage-grouse are relatively unlikely to use many burned areas within 20 years of fire, regardless of treatment. Understory habitat conditions are more likely to be adequate than overstory conditions, but in most climates, establishing forbs and reducing cheatgrass dominance is unlikely. Reestablishing sagebrush cover will require more than 20 years using past restoration methods. Given current fire frequencies and restoration capabilities, protection of landscapes containing a mix of dwarf sagebrush and big sagebrush steppe, minimal human development, and low non-native plant cover may provide the best opportunity for conservation of sage-grouse habitats.

AB After rapid deforestation in the eastern United States, which generally occurred during the period of 1850-1920, forests did not return to historical composition and structure. We examined forest compositional change and then considered how historical land use and current land use may influence forests in a grassland-forest landscape, the Missouri Plains, where frequent surface fire was the historical land use and intensive agricultural is the current land use. We compared composition, distribution, and environmental relationships during historical (1813-1860) and current (2004-2008) forest surveys. We also examined changing composition of life history strategies of (1) stress tolerators based on fire tolerance, (2) colonizers based on shade intolerance, and (3) competitors based on shade tolerance. Open forest ecosystems of fire-tolerant oaks have been replaced by forests of fire-sensitive species, such as ashes, hackberry, and maples that expanded from riparian firebreaks and osage-orange and eastern redcedar that expanded from planted windbreaks and rocky firebreaks. Colonizing species increased from 7% to 32% of total composition, with assisted tree migration from planting; we expect continued expansion particularly by eastern redcedar into areas unoccupied by trees. Competitive species have increased slightly to 38% of total composition although the trajectory of current forests suggested competitors may increase to 56% of total composition by replacing oaks in forest ecosystems. Changed success of life history strategies in an agricultural landscape without fire resulted in increased composition and extent of fire-sensitive colonizers compared to fire-tolerant oaks. We suggest that patterns of loss of fire-tolerant oaks and increased distribution of fire-sensitive species reflect suppression of fire, the historical land use. In addition, we suggest that subsequent land use dictates the success of either shade-intolerant colonizers or shade-tolerant competitors in current forests. Forests will be composed of shade-intolerant colonizers where land use disturbance is frequent, such as in agricultural landscapes, and forests will be composed of species with greater shade tolerance where land use disturbance is less frequent.

AB Forest conditions prior to extensive land clearing are often used as a point-of-reference by ecologists and resource managers for characterizing the historical range of variability in forest conditions shaped by intact disturbance regimes. Quantitative data on forest reference conditions can be developed from forest surveys and reconstructions using dendroecology; however, these methods lack the spatial resolution needed for landscape management. In this paper, we combine predictive vegetation mapping methods with reference forest conditions inferred from early forest surveys, dendroecology, and fire simulation models to develop landscape-scale reference conditions for forest structure, forest fuels, fire frequency, and fire behavior using the Lake Tahoe Basin, California as an example.
The dendroecological reconstruction method used for the Lake Tahoe Basin forests was not sensitive to variation in decomposition rates suggesting that our method provided robust estimates of reference period forest characteristics. The cluster analysis procedure identified five forest structure types (white fir, Jeffrey pine, red fir, lodgepole pine, and subalpine) and 15 subtypes. Each forest type had a characteristic composition, density, and basal area. Our random forests approach to classifying and mapping the spatial distribution of the five dominant reference forest structure types resulted in 51.5% classification accuracy using 14 physiographic and climatic variables. The random forests model to identify subtypes within each forest group had an average percent correct classification of 47.8%. The random forests model for fire intervals explained 67% of the variance in the point fire return interval estimates from fire-scarred trees. Estimates of reference period fuels modeled from stand structure suggested moderate fuel loads for reference forests. The predicted potential fire type for forest subtypes under extreme weather was surface fire except for red fir and the lodgepole pine subtypes with potential for crown fire. By characterizing the reference forest composition, structure, and disturbance frequency with a range of variability, managers can develop a forested landscape more resilient to changes in disturbance regime and climate. Although our approach was developed for the Lake Tahoe Basin, California, it could be applied to a wide range of forest landscapes to identify forest reference conditions.

AB Many of the most dramatic and surprising effects of global change on ecological systems will occur across large spatial extents, from regions to continents. Multiple ecosystem types will be impacted across a range of interacting spatial and temporal scales. The ability of ecologists to understand and predict these dynamics depends, in large part, on existing site-based research infrastructures developed in response to historic events. Here we review how unevenly prepared ecologists are, and more generally, ecology is as a discipline, to address regional- to continental-scale questions given these pre-existing site-based capacities, and we describe the changes that will be needed to pursue these broad-scale questions in the future. We first review the types of approaches commonly used to address questions at broad scales, and identify the research, cyber-infrastructure, and cultural challenges associated with these approaches. These challenges include developing a mechanistic understanding of the drivers and responses of ecosystem dynamics across a large, diverse geographic extent where measurements of fluxes or flows of materials, energy or information across levels of biological organization or spatial units are needed. The diversity of methods, sampling protocols, and data acquisition technologies make post-hoc comparisons of ecosystems challenging, and data collected using standardized methods across sites require coordination and teamwork. Sharing of data and analytics to create derived data products are needed for multi-site studies, but this level of collaboration is not part of the current ecological culture. We then discuss the strengths and limitations of current site-based research infrastructures in meeting these challenges, and describe a path forward for regional- to continental-scale ecological research that integrates existing infrastructures with emerging and potentially new technologies to more effectively address broad-scale questions. This new research infrastructure will be instrumental in developing an ``uber network'' to allow users to seamlessly identify and select, analyze, and interpret data from sites regardless of network affiliation, funding agency, or political affinity, to cover the spatial variability and extent of regional- to continental-scale questions. Ultimately, scientists must network across institutional boundaries in order to tap and expand these existing network infrastructures before these investments can address critical broad-scale research questions and needs.

AB An adult Silver Carp Hypophthalmichthys molitrix with a focally extensive skin lesion near the caudal peduncle and mild iridial hemorrhage was submitted to the Aquatic Research and Diagnostic Laboratory (ARDL) in Stoneville, Mississippi, as part of a fish kill investigation. Touch impressions of this musculoskeletal lesion revealed small cocci (similar to 1 mu m) in pairs or chains within an inflammatory milieu. A pure Gram-positive cocci isolate was obtained from the brain, while cultures of the kidney and muscle yielded multiple bacterial colony types, including the Gram-positive cocci seen in the brain. This brain isolate was characterized biochemically and identified as Lactococcus spp. Analysis of the near complete 16S small subunit ribosomal DNA (SSU rDNA) and DNA gyrase subunit B (gyrB) gene sequences revealed the bacterium to be L. lactis subsp. lactis (SSU rDNA: 100% identity, 1,372/1,372bp; gyrB: 99.7% identity, 1,779/1,785bp). Comparatively, at the gyrB locus the case isolate shared less than 90% similarity to L. lactis subsp. cremoris (1,599/1,781bp) and less than 80% homology to L. garvieae (1409/1775bp). Histopathological examination confirmed a severe meningoencephalitis, a moderate mononuclear myositis, and a mild interstitial nephritis. We believe this represents the first report of a natural infection by L. lactis subsp. lactis in Silver Carp.

AB Basic information on species distribution and abundance is often lacking, even for common species. The historically abundant Mountain Yellow-legged (Rana sp.) and Pacific Treefrog (Pseudacris sp.) species complexes occur sympatrically and are exposed to similar threats. We evaluated the status of these species complexes on national forest lands in the Sierra Nevada, California as part of a long-term bioregional amphibian monitoring program. To determine occupancy and abundance indices, we surveyed all lentic and a sample of lotic habitats in 208 small watersheds (2-4 km(2)) selected using an unequal probability design where watersheds occupied previously had a higher likelihood of being selected. For Rana sp., results corroborated other assessments that the taxon has declined substantially. We found breeding activity in an estimated 0.04 (SE = 0.01) of watersheds rangewide, 0.47 (SE = 0.04) of watersheds with locality data from 1990-2001, and 0.02 (SE = 0.03) of watersheds with locality data prior to 1990. Less than 10% of the watersheds contained large numbers of frogs (>500 tadpoles or 100 adults + subadults). In contrast, treefrogs were still distributed widely, with breeding occurring in an estimated 0.25 (SE = 0.01) of watersheds rangewide and 0.95 (SE = 0.02) of watersheds where the taxon was assumed to have occurred historically. The status of Rana sp. is consistent with broad-scale predictions that highly aquatic, specialized anuran species have an increased extinction risk. The delayed recognition of the severity of Rana sp. declines underscores the value of an early warning monitoring system for all species including common ones.

AB In recent years finite-mixture models have been employed to approximate and model empirical diameter at breast height (DBH) distributions. We used two-component mixtures of either the Weibull distribution or the gamma distribution for describing the DBH distributions of mixed-species, two-cohort forest stands, to analyse the relationships between the DBH components, age cohorts and dominant species, and to assess the significance of differences between the mixture distributions and the kernel density estimates. The data consisted of plots from the Swietokrzyski National Park (Central Poland) and areas close to and including the North Carolina section of the Great Smoky Mountains National Park (USA; southern Appalachians). The fit of the mixture Weibull model to empirical DBH distributions had a precision similar to that of the mixture gamma model, slightly less accurate estimate was obtained with the kernel density estimator. Generally, in the two-cohort, two-storied, multi-species stands in the southern Appalachians, the two-component DBH structure was associated with age cohort and dominant species. The 1st DBH component of the mixture model was associated with the 1st dominant species sp1 occurred in young age cohort (e.g., sweetgum, eastern hemlock); and to a lesser degree, the 2nd DBH component was associated with the 2nd dominant species sp2 occurred in old age cohort (e.g., loblolly pine, red maple). In two-cohort, partly multilayered, stands in the Swietokrzyski National Park, the DBH structure was usually associated with only age cohorts (two dominant species often occurred in both young and old age cohorts). When empirical DBH distributions representing stands of complex structure are approximated using mixture models, the convergence of the estimation process is often significantly dependent on the starting strategies. Depending on the number of DBHs measured, three methods for choosing the initial values are recommended: min.k/max.k, 0.5/1.5/mean, and multistart. For large samples (number of DBHs measured >= 80) the multistage method is proposed - for the two-component mixture Weibull or gamma model select initial values using the min.k/max.k (for k = 1,5,10) and 0.5/1.5/mean methods, run the numerical procedure for each method, and when no two solutions are the same, apply the multistart method also.

AB Use of high-elevation balds by Nearctic-Neotropical passerines remains a poorly understood component of migration ecology. We used radio-telemetry to assess the habitat use of 20 Oreothlypis peregrina (Tennessee Warbler) at a high-elevation bald during September 2011. Our goals were to estimate the duration of stopover, examine variation in stopover length by age class, and determine patterns of habitat use during fall migration. For radio-tracked birds, the average length of time spent at the bald was 4.6 days (range: 1-12 days). The majority of tracked locations corresponded with heath habitat that surrounded the bald opening (79% of locations), relative to the more distal and less complex, hardwood forest. Collectively, these results provide information on the important, yet ephemeral role that high-elevation balds play in supporting the autumnal migration of eastern North American passerines.

TI Interactions Between Wildlife and Civil Aircraft in Mississippi

DT Article
ID BIRD STRIKES; MANAGEMENT; COLLISIONS; PATTERNS; RISK
AB Collisions between aircraft and wildlife have increased markedly since first recorded in 1905. These strikes threaten human safety and cost the United States civil aviation industry >$677 million annually. We examined the Federal Aviation Administration's national wildlife strike database records from 1990-2010 to characterize reported strikes with civil aircraft in Mississippi. We hypothesized that daily foraging patterns and seasonal differences would affect strike frequency for birds. We summarized 381 reported strikes (366 birds, 14 mammals and 1 reptile) comprising >= 42 species. Bird strikes per 1000 aircraft operations (take-off and landing counted as separate operations) increased between 1990-2010. The monthly number of reported strikes per 1000 operations peaked July September, coinciding with late breeding season and fall migration. Bird strikes per 1000 operations occurred more often during runway approach than during take-off, and more often at dusk than during other times of day. These patterns mirrored nationally observed wildlife-strike patterns. Our results may aid airport biologists in Mississippi to prioritize species management and more effectively implement timing and types of animal control efforts.

AB Although the term "whole grain" is well defined, there has been no universal standard of what constitutes a "whole-grain food," creating challenges for researchers, the food industry, regulatory authorities, and consumers around the world. As part of the 2010 Dietary Guidelines for Americans, the U.S. Dietary Guidelines Technical Advisory Committee issued a call to action to develop definitions for whole-grain foods that could be universally accepted and applied to dietary recommendations and planning. The Committee's call to action, and the lack of a global whole-grain food definition, was the impetus for the Whole Grain Roundtable held 3-5 December 2012 in Chicago, Illinois. The objective was to develop a whole-grain food definition that is consistent with the quartet of needs of science, food product formulation, consumer behavior, and label education. The roundtable's expert panel represented a broad range of expertise from the United States and Europe, including epidemiology and dietary intervention researchers, consumer educators, government policy makers, and food and nutrition scientists from academia and the grain food industry. Taking into account the totality, quality, and consistency of available scientific evidence, the expert panel recommended that 8 g of whole grain/30 g serving (27 g/100 g), without a fiber requirement, be considered a minimum content of whole grains that is nutritionally meaningful and that a food providing at least 8 g of whole grains/30-g serving be defined as a whole-grain food. Having an established whole-grain food definition will encourage manufacturers to produce foods with meaningful amounts of whole grain, allow consistent product labeling and messaging, and empower consumers to readily identify whole-grain foods and achieve whole-grain dietary recommendations.

AB Freeze avoidance has evolved in plants in response to selection pressures brought about by exposure to freezing temperatures. It is a multifaceted adaptive mechanism with many attributes. Despite the prevalence of freeze avoidance as an adaptive mechanism, little research has been devoted in recent times to understanding the underlying mechanisms and regulation of freeze avoidance. Therefore, there is no shortage of questions that need to be addressed. Inherent in understanding how plants respond to freezing temperatures is the need to also understand the properties of water at different temperatures and how the interaction of water with biological substances affects these properties. This review provides an overview of the subject of biological ice nucleation and propagation and how various aspects of plant structure and composition can affect the freezing process. Deep supercooling of plant tissues represents the most extreme example of freeze avoidance. The potential role of anti-nucleating substances in defining the ability to deep supercool is also discussed. The importance of studying intact plants in their natural environments is emphasized. Although, this adds a high degree of complexity to investigations, it is in this context that adaptive mechanisms have evolved and play a role in the biology and survival of plants.

AB This paper examines how knowledge-action systems - the networks of actors involved in the production, sharing and use of policy-relevant knowledge - work in the process of developing sustainable strategies for cities. I developed an interdisciplinary framework - the knowledge-action system analysis (KASA) framework - that integrates concepts of the co-production of knowledge and social order with social network analysis tools to analyze existing configurations of knowledge-action systems in the city of San Juan, Puerto Rico, and how these are shaping both what we know and how we envision the future of cities. I applied KASA in the context of land use and green area governance and found that a diverse network of actors are contributing diverse knowledge types, thus showing potential for innovation in governance. This potential is conditioned, however, by various political and cultural factors, such as: (1) actors dominating knowledge about land use are the same ones that control urban land resources, (2) conventional planning expertise and procedures dominate over other alternative ways of knowing; (3) multiple visions and boundary arrangements co-exist in the city, and (4) boundary spanning opportunities limited by assumptions that knowledge and action should be done in distinct spheres of city planning. This study shows that developing adaptive and innovative capacities for sustainability is not solely a matter of harnessing more science, but about managing the politics of knowledge and visions that emerge from complex governance systems.

AB Novel wheat lines with altered flour compositions can be used to decipher the roles of specific gluten proteins in flour quality. Grain proteins from transgenic wheat lines in which genes encoding the omega-5 gliadins were silenced by RNA interference (RNAi) were analyzed by quantitative 2-dimensional gel electrophoresis (2-DE). The precise effects of the genetic modifications on the proteome were assessed in four homozygous lines generated with the same RNAi construct. Two of the lines showed >80% decreases in omega-5 gliadins with only small changes in the levels of other gluten proteins. In the other two lines, omega-5 gliadins were not detectable by 2-DE. However, there were notable reductions in all omega-1,2 gliadins. Small decreases in several other gluten proteins were also detected in one of the lines. The other line showed notable decreases in three HMW-GS and an s-type LMW-GS, increases in two m-type LMW-GS and several alpha gliadins, as well as increases in both serpins and triticin. The study demonstrates that the same RNAi construct can have differential effects on the wheat grain proteome and highlights the importance of detailed proteomic analyses of transgenic grain prior to selecting lines for further assessment of flour quality and allergenic potential.

AB The chemical induced barley mutant m351 was first selected for its low level of mixed-linkage (1-3,1-4) beta-D-glucan (MLG) in an experimental effort to search for barley lines with varied grain MLG contents. The MLG decrease in m351 was associated with increased levels of fructans and crude fiber, but maintained the same plant characteristics under field conditions. The mutation was mapped to a genetic locus flanked by two SSR markers, Bmag369 and Bmag564, on chromosome 7H. Molecular cloning of the CslF6 gene from the m351 line revealed the presence of a point mutation, causing a substitution of an alanine for threonine at position 849 in the amino acid sequence of the corresponding protein. The resultant protein retains some functionality and affects other components in the m351 grain. Those metabolic changes associated with MLG reduction in m351 is the first case reported of a partially functional CslF6 gene in cereal grains. The results contribute to better understanding of the functional effects of the CslF6 gene and the mutant has potential implications in grain end-use quality improvement. Published by Elsevier Ltd.

DE hair Se content; historical Se data; grain consumption
ID HUMAN HEALTH; AREA
AB The selenium (Se) content in human hair is useful as an indicator of human Se intake and status. In this regard, when measuring the hair Se concentrations in Chinese inhabitants across northeast to southeast China, the results indicated that generally 84% of all residents have normal hair Se content. Between the sexes, the average hair Se content of males was higher than that of females, irrespective of districts. When comparing geographical regions, the average hair Se content of southern residents was greater than that of northern residents, regardless of gender. Historically, the overall hair Se content of today's inhabitants decreased between 24% and 46% when compared with the inhabitants living in the same geographic region 20 years ago. The decrease of hair Se content may be related to the overall decrease of grain consumption and the lower Se content in the staple food rice.

AB Zinc is a vital micronutrient used for over 300 enzymatic reactions and multiple biochemical and structural processes in the body. To date, sensitive and specific biological markers of zinc status are still needed. The aim of this study was to evaluate Gallus gallus as an in vivo model in the context of assessing the sensitivity of a previously unexplored potential zinc biomarker, the erythrocyte linoleic acid: dihomo--linolenic acid (LA:DGLA) ratio. Diets identical in composition were formulated and two groups of birds (n = 12) were randomly separated upon hatching into two diets, Zn(+) (zinc adequate control, 42.3 g/g zinc), and Zn(-) (zinc deficient, 2.5 g/g zinc). Dietary zinc intake, body weight, serum zinc, and the erythrocyte fatty acid profile were measured weekly. At the conclusion of the study, tissues were collected for gene expression analysis. Body weight, feed consumption, zinc intake, and serum zinc were higher in the Zn(+) control versus Zn(-) group (p < 0.05). Hepatic TNF-, IL-1, and IL-6 gene expression were higher in the Zn(+) control group (p < 0.05), and hepatic (6) desaturase was significantly higher in the Zn(+) group (p < 0.001). The LA:DGLA ratio was significantly elevated in the Zn(-) group compared to the Zn(+) group (22.6 +/- 0.5 and 18.5 +/- 0.5, % w/w, respectively, p < 0.001). This study suggests erythrocyte LA:DGLA is able to differentiate zinc status between zinc adequate and zinc deficient birds, and may be a sensitive biomarker to assess dietary zinc manipulation.

AB A molecular survey was conducted for several hemoparasites of domestic dogs and three species of wild carnivores from two sites in Zambia. Three Babesia spp. were detected including Babesia felis and Babesia leo in lions (Panthera leo) and a Babesia sp. (similar to Babesia lengau) in spotted hyenas (Crocuta crocuta) and a single lion. All wild dogs (Lycaon pictus) and domestic dogs were negative for Babesia. High prevalences for Hepatozoon were noted in all three wild carnivores (38-61 %) and in domestic dogs (13 %). Significantly higher prevalences were noted in hyenas and wild dogs compared with domestic dogs and lions. All carnivores were PCR negative for Ehrlichia canis, Ehrlichia ewingii, and Bartonella spp. Overall, high prevalences and diversity of Babesia and Hepatozoon were noted in wild carnivores from Zambia. This study is the first molecular characterization of Babesia from any hyena species and is the first report of a Babesia sp. closely related to B. lengau, a parasite previously only reported from cheetahs (Acinonyx jubatus), in lions and hyenas. Although usually benign in wild carnivores, these hemoparasites can be pathogenic under certain circumstances. Importantly, data on vectors for these parasites are lacking, so studies are needed to identify vectors as well as determine transmission routes, infection dynamics, and host specificity of these hemoparasites in wildlife in Africa and also the risk of transmission between domestic animals and wildlife.

AB Wastewater reclamation for municipal irrigation is an increasingly attractive option for extending water supplies. However, public health concerns include the potential for development of antibiotic resistance (AR) in environmental bacteria after exposure to residual pharmaceuticals in reclaimed water. Though scientific studies have reported high levels of AR in soils irrigated with wastewater, these works often fail to address the soil resistome, or the natural occurrence of AR. This study compared AR patterns in sediment Enterococcus isolated from water storage basins containing either reclaimed water or groundwater in central Arizona. Resistance to 16 antibiotics was quantified in isolates to a depth of 30 cm. Results reveal high levels of resistance to certain antibiotics, including lincomycin, ciprofloxacin, and erythromycin, exists in sediments regardless of the water source (groundwater, reclaimed water), and higher AR was not detectable in reclaimed water sediments. Furthermore, multiple-antibiotic-resistance (MAR) was substantially reduced in isolates from reclaimed water sediments, compared to freshwater sediment isolates. Comparing the development of AR in sediment bacteria at these two sites will increase awareness of the environmental and public health impacts of using reclaimed water for irrigation of municipal areas, and illustrates the necessity for control sites in studies examining AR development in environmental microbiota.

AB Mexican Spotted Owls (Strix occidentalis lucida) are common in older forests within their range but also persist in many areas burned by wildfire and may selectively forage in these areas. One hypothesis explaining this pattern postulates that prey abundance increases in burned areas following wildfire. We observed movement to wintering areas within areas burned by wildfire by four radio-marked Mexican Spotted Owls in the Sacramento Mountains, New Mexico. These movements occurred during the winters of 2004-2005 and 2005-2006, with some owls migrating in both winters and others in only one. Wintering areas of these owls occurred within the perimeters of two wildfires that burned in May 2000 and April 2002, respectively. We estimated relative prey abundance and biomass during December 2006 within paired burned wintering areas and nest core areas used by these owls. Species richness and relative abundance of small mammals were greater in the burned wintering areas than in the associated nest core areas for all four owls, and estimated prey biomass ranged from 2-6 times greater in burned wintering areas relative to the paired nest core areas. Burned wintering areas used by these owls were similar in elevation to their nest core areas, and likely experienced similar weather conditions during winter. These results suggest that wintering owls moved to areas with greater food resources, rather than to areas with milder weather. They further suggest that relative prey abundance was greater in burned wintering areas than in the nest core areas >5 years post-fire, and that these burned wintering areas provided important habitat for Mexican Spotted Owls in our study area during an energetically stressful season.

AB Despite being widespread and abundant, little is known about the breeding ecology and natural history of the Eastern Wood-Pewee (Contopus virens), in part because nests are often high in the canopy, difficult to view, and adults are monomorphic. We monitored nests of Eastern Wood-Pewees and recorded the feeding rate of nestlings by adults as part of a larger study on breeding demography of Eastern Wood-Pewees across a gradient of savanna, woodland, and forest in the Missouri Ozarks in 2010-2011. We monitored 287 nests between 26 May and 22 August and conducted feeding rate observations for 54 nests with nestlings. There was an 88-day nesting season with peaks of nest activity on 24 June and 22 July. We recorded 19 cases of double brooding and nine cases of within-season nest reuse. Seasonal fecundity was 2.2 fledglings per territory. The frequency of parental feeding visits increased with nestling age. These are additional observations of nest reuse, nesting cycle lengths, and breeding season length for Eastern Wood-Pewees; future demographical research of marked individuals will continue to fill in gaps in breeding ecology for this common and widespread flycatcher.

AB In this study, micro-hydrodistillation (MHD) was conducted for the determination of volatile aroma compounds (VACs) in fresh and dried leaves of citronella grass, lemongrass, and citronella incense products. Optimum extraction of VACs was achieved when extractions were performed at 100 degrees C with 0.5 g of sample in 3 mL of water for 60 min. Maximum recovery of VACs was achieved using hexane (2 mL) as extraction solvent. Six major VACs extracted from citronella grass were identified as citronellal, citronellol, neral, geranial, geraniol, and eugenol. Geraniol was the predominant VAC in citronella grass and neral was the major VAC extracted from the lemongrass leaves. Eugenol was not detected in lemongrass leaves extract. The validated method provided good recoveries of VACs ranging from 83.6 to 105.3% with the relative standard deviations of 6.2 to 11.0%. The results presented in this paper show that the amount of essential oils extracted from the fresh citronella grass and lemongrass leaves was significantly higher as compared to those extracted from leaves dried at the ambient room temperature for 3 days. Quantities of geraniol, eugenol, and neral extracted from leaves using MHD can be used as marker compounds to differentiate citronella grass from lemongrass leaves extracts. Both storage time and conditions significantly influenced the amount of VACs extracted from citronella incense products.

AB Breast cancer is the second leading cause of cancer mortality in women, estimated at nearly 40,000 deaths and more than 230,000 new cases diagnosed in the U. S. this year alone. One of the defining characteristics of breast cancer is the radiographic presence of microcalcifications. These palpable mineral precipitates are commonly found in the breast after formation of a tumor. Since free Ca2+ plays a crucial role as a second messenger inside cells, we hypothesize that these chelated precipitates may be a result of dysregulated Ca2+ secretion associated with tumorigenesis. Transient and sustained elevations of intracellular Ca2+ regulate cell proliferation, apoptosis and cell migration, and offer numerous therapeutic possibilities in controlling tumor growth and metastasis. During lactation, a developmentally determined program of gene expression controls the massive transcellular mobilization of Ca2+ from the blood into milk by the coordinated action of calcium transporters, including pumps, channels, sensors and buffers, in a functional module that we term CALTRANS. Here we assess the evidence implicating genes that regulate free and buffered Ca2+ in normal breast epithelium and cancer cells and discuss mechanisms that are likely to contribute to the pathological characteristics of breast cancer.

AB LANDIS PRO predicts forest composition and structure changes incorporating species-, stand-, and landscape-scales processes at regional scales. Species-scale processes include tree growth, establishment, and mortality. Stand-scale processes contain density- and size-related resource competition that regulates self-thinning and seedling establishment. Landscape-scale processes include seed dispersal and disturbances. LANDIS PRO is designed to be compatible with forest inventory data, thus extensive inventory data can be directly utilized to initialize and calibrate model parameters before predicting future forest changes. LANDIS PRO allows for exploring the effects of disturbances, management, climate change, and modeling the spread of invasive species. We demonstrate that LANDIS PRO successfully predicts forest successional trajectories and stand development patterns in the Central Hardwood Forest region in U.S.

AB The US Environmental Protection Agency and several U.S. states and Canadian provinces are currently developing national water quality criteria for selenium that are based in part on toxicity tests performed by feeding freshwater fish a selenomethionine-spiked diet. Using only.,selenomethionine to examine the toxicity of selenium is based in part on the limitations of the analytical chemistry methods commonly used in the 1990s and 2000s to speciate selenium in freshwater biota. While these methods provided a good starting point, recent improvements in analytical chemistry methodology have demonstrated that selenium speciation in biota is far more complex than originally thought. Here, we review the recent literature that suggests that there are numerous additional selenium species present in freshwater food chains and that the toxicities of these other selenium species, both individually and in combination, have not been evaluated in freshwater fishes. Evidence from studies on birds and mammals suggests that the other selenium forms differ in their metabolic pathways and toxicity from selenomethionine. Therefore, we conclude that toxicity testing using selenomethionine-spiked feed is only partly addressing the question "what is the toxicity of selenium to freshwater fishes?" and that using the results of these experiments to derive freshwater quality criteria may lead to biased water quality criteria. We also discuss additional studies that are needed in order to derive a more ecologically relevant freshwater quality criterion for selenium.

AB Forest decline played a pivotal role in motivating Europe's political focus on sustainability around 35 years ago. Silver fir (Abies alba) exhibited a particularly severe dieback in the mid-1970s, but disentangling biotic from abiotic drivers remained challenging because both spatial and temporal data were lacking. Here, we analyze 14 136 samples from living trees and historical timbers, together with 356 pollen records, to evaluate recent fir growth from a continent-wide and Holocene-long perspective. Land use and climate change influenced forest growth over the past millennium, whereas anthropogenic emissions of acidic sulfates and nitrates became important after about 1850. Pollution control since the 1980s, together with a warmer but not drier climate, has facilitated an unprecedented surge in productivity across Central European fir stands. Restricted fir distribution prior to the Mesolithic and again in the Modern Era, separated by a peak in abundance during the Bronze Age, is indicative of the long-term interplay of changing temperatures, shifts in the hydrological cycle, and human impacts that have shaped forest structure and productivity.

AB Mega-fires are often defined according to their size and intensity but are more accurately described by their socioeconomic impacts. Three factors - climate change, fire exclusion, and antecedent disturbance, collectively referred to as the "mega-fire triangle" - likely contribute to today's mega-fires. Some characteristics of mega-fires may emulate historical fire regimes and can therefore sustain healthy fire-prone ecosystems, but other attributes decrease ecosystem resiliency. A good example of a program that seeks to mitigate mega-fires is located in Western Australia, where prescribed burning reduces wildfire intensity while conserving ecosystems. Crown-fire-adapted ecosystems are likely at higher risk of frequent mega-fires as a result of climate change, as compared with other ecosystems once subject to frequent less severe fires. Fire and forest managers should recognize that mega-fires will be a part of future wildland fire regimes and should develop strategies to reduce their undesired impacts.

AB Raspberries are a delicate, high-value crop with an extremely short shelf life exacerbated by postharvest decay Caused by Botrytis cinerea Pers. European red raspberry (Rubus idaeus L.) is the most widely grown variety. Yellow (R. idaeus L.), black (R. occidentalis L.), and purple raspberries (R. X neglectus Peck. or R. occidentalis X idaeus hybrids) are available mainly at local markets and U-pick farms. To compare the postharvest quality of the raspberry color groups, pesticide-free fruit from cultivars and breeding selections of red, yellow, purple, and black raspberries were examined for oxygen radical absorbance capacity (ORAC), phenolics, anthocyanins, soluble solids, titratable acids, pH, color, firmness, decay and juice leakage rates, ethylene evolution, and respiration. There were significant correlations between decay rate and physio-chemical properties. Both decay and leakage rates were correlated with weather conditions before harvest, but each color group responded differently to different weather factors. There were no correlations among changes in color, firmness, decay, or juice leakage rates. All the other color groups were less acidic than the familiar red raspberry. Yellow raspberries had the worst decay rates but the best leakage rates. Black and purple raspberries, with the highest phenolics and anthocyanins and the lowest ethylene evolution rates, resisted decay the longest but bled soonest.

AB Candidatus Liberibacter asiaticus (Las) is a phloem-limited bacterium associated with huanglongbing (HLB), one of the most destructive diseases of citrus in Florida and other citrus-producing countries. Natural transmission of Las occurs by the psyllid vector Diaphorina can, but transmission can also occur through grafting with diseased budwood. As a result of the difficulty of maintaining Las in culture, screening of citrus germplasm for HLB resistance often relies on graft inoculation as the mode of pathogen transmission. This study evaluates transmission efficiencies and HLB progression in graft-inoculated and psyllid-inoculated citrus under greenhouse and natural conditions in the field. Frequencies of transmission in graft-inoculated greenhouse-grown plants varied between experiments and were as high as 90% in susceptible sweet orange plants 6 to 12 months after inoculation. Transmission frequency in a tolerant Citrus X Poncirus genotype (US-802) was 31% to 75%. In contrast, transmission of Las after controlled psyllid inoculation did not exceed 38% in any of four experiments in this study. Whereas the time from inoculation to detection of Las by polymerase chain reaction (PCR) was faster in psyllid-inoculated US-802 plants compared with graft-inoculated US-802 plants, it was similar in graft- and psyllid-inoculated sweet orange plants. HLB symptom expression was indistinguishable in graft- and psyllid-inoculated plants but was not always associated with the number of bacteria in affected leaves. The highest number of Las genomes per gram leaf tissue measured in sweet orange plants was one to four x 10(7) in graft-inoculated plants and one to two x 10(7) in psyllid-inoculated plants. Highest numbers measured in tolerant US-802 plants were one to three x 10(6) and two to six x 10(6), respectively. Compared with artificial inoculation in a greenhouse setting, natural inoculation of field-grown sweet orange trees occurred at a much slower pace, requiring more than 1 year for infection incidence to reach 50% and a minimum of 3 years to reach 100%.

AB Bordetella bronchiseptica is pervasive in swine populations and plays multiple roles in respiratory disease. Most studies addressing virulence factors of B. bronchiseptica utilize isolates derived from hosts other than pigs in conjunction with rodent infection models. Based on previous in vivo mouse studies, we hypothesized that the B. bronchiseptica type III secretion system (T3SS) would be required for maximal disease severity and persistence in the swine lower respiratory tract. To examine the contribution of the T3SS to the pathogenesis of B. bronchiseptica in swine, we compared the abilities of a virulent swine isolate and an isogenic T3SS mutant to colonize, cause disease, and be transmitted from host to host. We found that the T3SS is required for maximal persistence throughout the lower swine respiratory tract and contributed significantly to the development of nasal lesions and pneumonia. However, the T3SS mutant and the wild-type parent are equally capable of transmission among swine by both direct and indirect routes, demonstrating that transmission can occur even with attenuated disease. Our data further suggest that the T3SS skews the adaptive immune response in swine by hindering the development of serum anti-Bordetella antibody levels and inducing an interleukin-10 (IL-10) cell-mediated response, likely contributing to the persistence of B. bronchiseptica in the respiratory tract. Overall, our results demonstrate that the Bordetella T3SS is required for maximal persistence and disease severity in pigs, but not for transmission.

AB Background. As creatinine-based estimates of renal function are inaccurate in older adults, an alternative is an estimated glomerular filtration rate (eGFR(cys)) based on cystatin C. We examined the prospective association between chronic kidney disease (CKDcys) as determined by eGFR(cys) with the primary outcome of incident mobility disability and the secondary outcome of change in gait speed.
Methods. Framingham Offspring Study participants older than 60 years and free of mobility disability at baseline (1998-2001) were eligible. Baseline CKDcys was defined as eGFR(cys) less than 60 mL/min/1.73 m(2). At follow-up (2005-2008), the outcomes of mobility disability, defined as self-reported inability to walk 1/2 mile and/or climb a flight of stairs, and gait speed were measured. Logistic and linear regression models were adjusted for age, sex, body mass index, smoking, diabetes, C reactive protein, and physical activity.
Results. Of 1,226 participants, 230 (19%) had CKDcys at baseline. After a mean follow-up of 6.6 years, 185 (15%) developed mobility disability. Of those with CKDcys, 60 (26%) developed mobility disability. Those with CKDcys had greater odds of mobility disability in the age-and sex-adjusted (odds ratio [OR] 1.91, 95% CI 1.32, 2.75) and fully adjusted (OR 1.55, 95% CI 1.05, 2.31) models compared with those without CKDcys. In fully adjusted models, participants with CKDcys had greater gait speed declines than those without CKDcys (beta = 0.07 [SE 0.02], p = .0022).
Conclusion. CKDcys was associated with higher odds of incident mobility disability and greater decline in gait speed, highlighting the loss of physical independence in elders with CKD.

AB The multifunctional triple gene block protein 1 (TGB1) of the Potexvirus Alternanthera mosaic virus (AltMV) has been reported to have silencing suppressor, cellto-cell movement, and helicase functions. Yeast two hybrid screening using an Arabidopsis thaliana cDNA library with TGB1 as bait, and co-purification with TGB1 inclusion bodies identified several host proteins which interact with AltMV TGB1. Host protein interactions with TGB1 were confirmed by biomolecular fluorescence complementation, which showed positive TGB1 interaction with mitochondrial ATP synthase delta' chain subunit (ATP synthase delta'), light harvesting chlorophyll-protein complex I subunit A4 (LHCA4), chlorophyll a/b binding protein 1 (LHB1B2), chloroplast-localized IscA-like protein (ATCPISCA), and chloroplast beta-ATPase. However, chloroplast beta-ATPase interacts only with TGB1(L88), and not with weak silencing suppressor TGB1(p88). This selective interaction indicates that chloroplast beta-ATPase is not required for AltiVIV movement and replication; however, TRV silencing of chloroplast beta-ATPase in Nicotiana benthamiana induced severe tissue necrosis when plants were infected by AltMV TGB1(L88) but not AltMV TGB1(p88), suggesting that beta-ATPase selectively responded to TGB1(L88) to induce defense responses.

AB Advancing our ability to use invasive plants for producing commodities is central to the agricultural industry. Our objective was to evaluate Russian knapweed (Acroptilon repens [L.] DC.) as a winter feed supplement for ruminant livestock. In Experiment 1, we utilized three ruminally cannulated steers in a completely randomized design to compare the ruminal degradation characteristics of alfalfa and Russian knapweed. In the second experiment, Russian knapweed and alfalfa were compared as protein supplements using 48 midgestation, beef cows (530 +/- 5 kg) offered ad libitum hard fescue (Festuca brevipila Tracey) straw in an 84-d study. Treatments included an unsupplemented control and alfalfa or Russian knapweed provided on an iso-nitrogenous basis. In Experiment 1, the rate and effective degradability of neutral detergent fiber was greater for alfalfa compared with Russian knapweed (P <= 0.02). Ruminal lag time for NDF (period before measurable disappearance began) was greater for knapweed (P=0.03). Soluble nitrogen, rate of N degradation, rumen degradable N, and effective degradability of N were all greater for alfalfa compared with Russian knapweed (P < 0.01). In Experiment 2, supplementation increased (P < 0.01) cow weight gain and BCS compared to the unsupplemented control with no difference between alfalfa and Russian knapweed (P=0.47). There was no difference (P=0.60) in the quantity of straw offered between the unsupplemented cows and supplemented groups, but alfalfa fed cows were offered approximately 11% more (P=-0.03) than Russian knapweed-fed cows. Total DM offered to cows was greater (P < 0.01) for supplemented compared with unsupplemented cows with no difference noted between alfalfa and Russian knapweed (P=0.79). Russian knapweed is comparable to alfalfa as a protein supplement for beef cows consuming low-quality forage. Using Russian knapweed as a nutritional supplement can help solve two major production problems; managing an invasive weed, and providing a feedstuff that reduces an impediment in livestock production systems.

AB The presence of sagebrush (Artemisia tridentata) in rangelands has declined due to the invasion of annual grasses such as cheatgrass (Bromus tectorum) and the feedback between these flammable grasses and wildfire frequency. Monitoring the change and distribution of suitable habitat and fuel loads is an important aspect of sagebrush management, particularly under future climate conditions. Assessments of sagebrush biomass are used to monitor habitat for critical wildlife species, determine fire risk, and quantify carbon storage. Field techniques such as destructive and point-intercept sampling have been used to determine sagebrush biomass, but both of these techniques can be expensive and time consuming to implement. Light detection and ranging techniques, including airborne laser scanning and terrestrial laser scanning (TLS) have potential for rapidly assessing biomass in sagebrush steppe. This study used TLS to estimate biomass of 29 sagebrush plants in Reynolds Creek Experimental Watershed, Idaho. Biomass was estimated using TLS-derived volume, then compared with destructive samples to assess the estimation accuracy. This accuracy level was then contrasted with the estimates obtained using point-intercept sampling of the same plants. The TLS approach (R-2=0.90) was slightly better for predicting total biomass than point-intercept sampling (R-2=0.85). Prediction of green biomass, or production, was more accurate using TLS-derived volume (R-2=0.86) than point-intercept sampling (R-2=0.65). This study explores a promising new method to repeatedly monitor sagebrush biomass across extensive landscapes. Future work should focus on making this method independent of sensor type, scan distance, scan number, and study area.

TI Urban and agricultural soils: conflicts and trade-offs in the

AB On-going human population growth and changing patterns of resource consumption are increasing global demand for ecosystem services, many of which are provided by soils. Some of these ecosystem services are linearly related to the surface area of pervious soil, whereas others show non-linear relationships, making ecosystem service optimization a complex task. As limited land availability creates conflicting demands among various types of land use, a central challenge is how to weigh these conflicting interests and how to achieve the best solutions possible from a perspective of sustainable societal development. These conflicting interests become most apparent in soils that are the most heavily used by humans for specific purposes: urban soils used for green spaces, housing, and other infrastructure and agricultural soils for producing food, fibres and biofuels. We argue that, despite their seemingly divergent uses of land, agricultural and urban soils share common features with regards to interactions between ecosystem services, and that the trade-offs associated with decision-making, while scale- and context-dependent, can be surprisingly similar between the two systems. We propose that the trade-offs within land use types and their soil-related ecosystems services are often disproportional, and quantifying these will enable ecologists and soil scientists to help policy makers optimizing management decisions when confronted with demands for multiple services under limited land availability.

AB A field experiment was performed in a grassland at the NOAA-CREST-Soil Moisture Advanced Radiometric Testbed (CREST-SMART) facility, which includes a mobile L-band dual-polarized radiometer with an in situ soil temperature and soil moisture observation network, located near Millbrook, NY. During the day-long field campaign, intensive spatiotemporal measurements of L-band brightness temperatures, surface temperature, soil moisture, and soil temperature at 3-, 7-, and 12-cm depths were collected during three passes at 0830, 1130, and 1430 h. During the second and third passes, half of the field was irrigated. Soil roughness and water content of the short grass that remained after mowing the study area were measured. The Tau-Omega radiative transfer model was used to assess the performance of the soil moisture retrieval using measured soil temperatures at different depths. In addition, the collected microwave observations at the three different times of the day were used to assess the impact of the diurnal variation of soil temperature on the performance of soil moisture retrieval. Obtained results showed that the root mean square error (RMSE) decreased throughout the day to reach 0.03 m(3)/m(3) for the afternoon pass when 12-cm soil temperature values were used in the radiative transfer model. In addition, during the three different passes, the lowest RMSE was consistently obtained when the 12-cm soil temperature was used, which suggests that, for this investigated site, soil temperature at the 12-cm depth can be a surrogate for soil effective temperature when L-band microwave temperatures are used. In terms of diurnal variability, observations from the afternoon pass led to the highest agreement between observed and retrieved soil moisture values.

AB The efficacy of attractive toxic sugar baits (ATSB) with the active ingredient eugenol, an Environmental Protection Agency exempt compound, was evaluated against vector and nuisance mosquitoes in both laboratory and field studies. In the laboratory, eugenol combined in attractive sugar bait (ASB) solution provided high levels of mortality for Aedes aegypti, Culex quinquefasciatus, and Anopheles quadrimaculatus. Field studies demonstrated significant control: >70% reduction for Aedes atlanticus, Aedes. infirmatus, and Culex nigripalpus and >50% reduction for Anopheles crucians, Uranotaenia sapphirina, Culiseta melanura, and Culex erraticus three weeks post ATSB application. Furthermore, non-target feeding of six insect orders, Hymenoptera, Lepidoptera, Coleoptera, Diptera, Hemiptera, and Orthoptera, was evaluated in the field after application of a dyed-ASB to flowering and non-flowering vegetation. ASB feeding (staining) was determined by dissecting the guts and searching for food dye with a dissecting microscope. The potential impact of ATSB on non-targets, applied on green non-flowering vegetation was low for all non-target groups (0.9%). However, application of the ASB to flowering vegetation resulted in significant staining of the non-target insect orders. This highlights the need for application guidelines to reduce non-target effects. No mortality was observed in laboratory studies with predatory non-targets, spiders, praying mantis, or ground beetles, after feeding for three days on mosquitoes engorged on ATSB. Overall, our laboratory and field studies support the use of eugenol as an active ingredient for controlling important vector and nuisance mosquitoes when used as an ATSB toxin. This is the first study demonstrating effective control of anophelines in non-arid environments which suggest that even in highly competitive sugar rich environments this method could be used for control of malaria in Latin American countries.

AB Although the effects of fish oil supplements on airway inflammation in asthma have been studied with varying results, the independent effects of the fish oil components, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), administered separately, are untested. Here, we investigated airway inflammation and hyperresponsiveness using a mouse ovalbumin exposure model of asthma assessing the effects of consuming EPA (1.5% wt/wt), DHA (1.5% wt/wt), EPA plus DHA (0.75% each), or a control diet with no added omega-3 polyunsaturated fatty acids. Consuming these diets for 6 weeks resulted in erythrocyte membrane EPA contents (molar %) of 9.0 (+/- 0.6), 3.2 (+/- 0.2), 6.8 (+/- 0.5), and 0.01 (+/- 0.0)%; DHA contents were 6.8 (+/- 0.1), 15.6 (+/- 0.5), 12.3 (+/- 0.3), and 3.8 (+/- 0.2)%, respectively. The DHA group had the highest bronchoalveolar lavage (BAL) fluid eosinophil and IL-6 levels (P < 0.05). Similar trends were seen for macrophages, IL-4, and IL-13, whereas TNF-alpha was lower in omega-3 polyunsaturated fatty acid groups than the control (P < 0.05). The DHA group also had the highest airway resistance, which differed significantly from the EPA plus DHA group (P < 0.05), which had the lowest. Oxylipins were measured in plasma and BAL fluid, with DHA and EPA suppressing arachidonic acid-derived oxylipin production. DHA-derived oxylipins from the cytochrome P450 and 15-lipoxygenase pathways correlated significantly with BAL eosinophil levels. The proinflammatory effects of DHA suggest that the adverse effects of individual fatty acid formulations should be thoroughly considered before any use as therapeutic agents in asthma.

AB Ctenanthe kummeriana (E. Morren) Eichler (Marantaceae) is a cosmopolitan ornamental plant with esthetically appealing color and leaf shape. Pseudautomeris brasiliensis Walker (Lepidoptera: Saturniidae) and a nondescribed species of Stenoma (Lepidoptera: Elachistidae) defoliated this plant in the campus of the Federal University of Vicosa (UFV), Vicosa, Minas Gerais State, Brazil, inspiring the study of the association that prevails among these organisms. This could be a rare event, as the association of Lepidoptera with Marantaceae is scarce, with only two previous reports. The aim of this study was to monitor the caterpillars on the two crops of C. kummeriana, one in the "Horto Botanico" (HB) and another in the " Recanto da Cigarra" (RC) for a period of 1 yr, with particular attention to the shelters and damage caused; to assess the gregarious nature and the emergence of parasitoid and lepidopterans; and to provide an accurate morphologic diagnosis of a parasitoid. P. brasiliensis and Stenoma sp. were recorded after the rainy season, exhibiting similar distribution between HB and RC. Enicospilus tenuigena Kriechbaumer, 1901 (Hymenoptera: Ichneumonidae) emerged from 76.25% of the P. brasiliensis pupae. P. brasiliensis and Stenoma sp. defoliated the C. kummeriana plants between March and June in the UFV campus, whereas the parasitoid E. tenuigena reduced the populations of the first species.

AB Hexane extract of chinaberry, Melia azedarach L., unripe fruits obtained from different municipalities of Goias State, Brazil, were evaluated on the southern cattle tick, Rhipicephalus (Boophilus) microplus (Canestrini), engorged females. Hexanic extracts were assayed in decreasing concentrations from 0.25 to 0.0156% to determine effects on egg production and hatching. Efficacy on engorged females decreased as a result of the extracts from Goiania (100%), Professor Jamil (97.5 +/- 3.0%), Pirenopolis (95.1 +/- 2.4%), Morrinhos (86.8 +/- 9.4%), Caturao ' (41.8 +/- 29.3%), and Bela Vista de Goias (17.1 +/- 0.9%) municipalities. Canonical redundancy analysis indicated that the extract bioactivity was positively correlated with soil Ca2+, Mg2+, and P and negatively correlated with silt, K+, potential acidity, and organic matter. This study demonstrates that M. azedarach hexanic extract can dramatically reduce R. (B.) microplus reproductive capacity and that efficacy is strongly influenced by differences in soil constituents between collection sites.

AB A novel biobased epoxy monomer with conjugated double bonds, glycidyl ester of eleostearic acid (GEEA) was synthesized from tung oil fatty acids and characterized by H-1 and C-13 NMR. Differential scanning calorimeter analysis (DSC) and Fourier transform infrared spectroscopy (FT-IR) were utilized to investigate the curing process of GEEA with dienophiles and anhydrides. DSC indicated that GEEA could cross-link with both dienophiles and anhydrides through Diels-Alder reaction and epoxy/anhydride ring-opening reaction. Furthermore, Diels-Alder cross-link was much more active than the ring-opening of epoxy and anhydride in the curing process. FT-IR also revealed that GEEA successively reacted with dienophiles and anhydrides in both cross-linking methods. Dynamic mechanical analysis and mechanical tensile testing were used to study the thermal and mechanical properties of GEEA cured by maleic anhydride, nadic methyl anhydride and 1,1'-(methylenedi-4,1-phenylene)-bismaleimide. Due to the independence between the curing agents, dienophile and anhydride, a series of thermosetting polymers with various properties could be obtained by adjusting the composition of these two curing agents.

TI Stochastic Modeling of Imperfect Salmonella Vaccines in an Adult Dairy

AB Salmonella is a major cause of bacterial foodborne disease. Human salmonellosis results in significant public health concerns and a considerable economic burden. Dairy cattle are recognized as a key source of several Salmonella serovars that are a threat to human health. To lower the risk of Salmonella infection, reduction of Salmonella prevalence in dairy cattle is important. Vaccination as a control measure has been applied for reduction of preharvest Salmonella prevalence on dairy farms. Salmonella vaccines are usually imperfect (i.e., vaccines may provide a partial protection for susceptible animals, reduce the infectiousness and shedding level, shorten the infectious period of infected animals, and/or curb the number of clinical cases), and evaluation of the potential impacts of imperfect Salmonella vaccines at the farm level is valuable to design effective intervention strategies. The objective of this study was to investigate the impact of imperfect Salmonella vaccines on the stochastic transmission dynamics in an adult dairy herd. To this end, we developed a semi-stochastic and individual-based continuous time Markov chain (CTMC) vaccination model with both direct and indirect transmission, and applied the CTMC vaccination model to Salmonella Cerro transmission in an adult dairy herd. Our results show that vaccines shortening the infectious period are most effective in reducing prevalence, and vaccines decreasing host susceptibility are most effective in reducing the outbreak size. Vaccines with multiple moderate efficacies may have the same effectiveness as vaccines with a single high efficacy in reducing prevalence, time to extinction, and outbreak size. Although the environment component has negligible contributions to the prevalence, time to extinction, and outbreak size for Salmonella Cerro in the herd, the relative importance of environment component was not assessed. This study indicates that an effective vaccination program against Salmonella Cerro spread in the herd can be designed with (1) vaccines with a single high efficacy in reducing either the infectious period or susceptibility of the host, or (2) if such single high efficacy vaccines are not available, vaccines with multiple moderate efficacies may be considered instead. These findings are also of general value for designing vaccination program for Salmonella serotypes in livestock.

AB Corn is the most widely grown crop in the Americas, with annual production in the United States of approximately 332 million metric tons. Improved climate forecasts, together with climate-related decision tools for corn producers based on these improved forecasts, could substantially reduce uncertainty and increase profitability for corn producers. The purpose of this paper is to acquaint climate information developers, climate information users, and climate researchers with an overview of weather conditions throughout the year that affect corn production as well as forecast content and timing needed by producers. The authors provide a graphic depicting the climate-informed decision cycle, which they call the climate forecast-decision cycle calendar for corn.
