AB Rice (Oryza sativa L.) head-rice yield (HR) is a key export and domestic quality trait whose genetic control is poorly understood. With the goal of identifying genomic regions influencing HR, quantitative-trait-locus (QTL) mapping was carried out for quality-related traits in recombinant inbred lines (RILs) derived from crosses of common parent Cypress, a high-HR US japonica cultivar, with RT0034, a low-HR indica line (129 RILs) and LaGrue, a low-HR japonica cultivar (298 RILs), grown in two US locations in 2005-2007. Early heading increased HR in the Louisiana (LA) but not the Arkansas (AR) location. Fitting QTL-mapping models to separate QTL main and QTL x environment interaction (QEI) effects and identify epistatic interactions revealed six main-effect HR QTLs in the two crosses, at four of which Cypress contributed the increasing allele. Multi-QTL models accounted for 0.36 of genetic and 0.21 of genetic x environment interaction of HR in MY1, and corresponding proportions of 0.25 and 0.37 in MY2. The greater HR advantage of Cypress in LA than in AR corresponded to a genomewide pattern of opposition of HR-increasing QTL effects by AR-specific effects, suggesting a selection strategy for improving this cultivar for AR. Treating year-location combinations as independent environments resulted in underestimation of QEI effects, evidently owing to lower variation among years within location than between location. Identification of robust HR QTLs in elite long-grain germplasm is suggested to require more detailed attention to the interaction of plant and grain development parameters with environmental conditions than has been given to date.

AB This paper provides recommendations on experimental design for early-tier laboratory studies used in risk assessments to evaluate potential adverse impacts of arthropod-resistant genetically engineered (GE) plants on non-target arthropods (NTAs). While we rely heavily on the currently used proteins from Bacillus thuringiensis (Bt) in this discussion, the concepts apply to other arthropod-active proteins. A risk may exist if the newly acquired trait of the GE plant has adverse effects on NTAs when they are exposed to the arthropod-active protein. Typically, the risk assessment follows a tiered approach that starts with laboratory studies under worst-case exposure conditions; such studies have a high ability to detect adverse effects on non-target species. Clear guidance on how such data are produced in laboratory studies assists the product developers and risk assessors. The studies should be reproducible and test clearly defined risk hypotheses. These properties contribute to the robustness of, and confidence in, environmental risk assessments for GE plants. Data from NTA studies, collected during the analysis phase of an environmental risk assessment, are critical to the outcome of the assessment and ultimately the decision taken by regulatory authorities on the release of a GE plant. Confidence in the results of early-tier laboratory studies is a precondition for the acceptance of data across regulatory jurisdictions and should encourage agencies to share useful information and thus avoid redundant testing.

AB Values of the applied hydrodynamic torque (T-applied) and the resisting adhesive torque (T-adhesion) will determine whether a colloid will be immobilized (T-applied <= T-adhesion) or roll (T-applied > T-adhesion) on a solid water interface. Previous literature has demonstrated in 1-2 collector (grain) systems that the influence of T-applied on colloid retention can be significant under unfavorable attachment conditions and that only a fraction of the solid surface may contribute to retention. However, many questions remain on how to obtain, analyze, and upscale information on the forces and torques that act on colloids near solid surfaces in porous media. To address some of these gaps in knowledge, high resolution pore-scale water flow simulations were conducted for sphere packs (25 spheres) over a range of Darcy velocities, grain sizes and distributions, and porosities. The spatial variability of T-applied was calculated from this information, and successfully described using a lognormal cumulative density function (CDF). Linear interpolation and scaling techniques were subsequently used to predict the lognormal CDF of T-applied for various colloid sizes, grain sizes and distributions, and water velocities. The lognormal CDF of T-applied was then evaluated at select values of T-adhesion (i.e, interaction energy) to quantify the fraction and locations on the solid surface that contributes to colloid retention (S-f), and the theoretical maximum solid phase concentration of retained colloids (S-max).

It covers the major mycotoxins aflatoxins, Alternaria toxins, ergot alkaloids, fumonisins, ochratoxin, patulin, trichothecenes, and zearalenone. New and improved methods for mycotoxins continue to be published. Immunological-based method developments continue to be of wide interest in a broad range of formats. Multimycotoxin determination by LC-MS/MS is now being targeted at the specific ranges of mycotoxins and matrices of interest or concern to the individual laboratory. Although falling outside the main emphasis of the review, some aspects of natural occurrence have been mentioned, especially if linked to novel method developments.

AB Members of the Fusarium graminearum species complex (Fg complex) are the causal agents of ear rot in maize and Fusarium head blight of wheat and other small grain cereals. The potential of these pathogens to contaminate cereals with trichothecene mycotoxins is a health risk for both humans and animals. A survey of ear rot isolates from maize collected in northwest Argentina recovered 66 isolates belonging to the Fg complex. A multilocus genotyping (MLGT) assay for determination of Fg complex species and trichothecene chemotypes was used to identify 56 of these isolates as F. meridionale and 10 isolates as F. boothii. F. meridionale was fixed for the nivalenol (NIV) chemotype, and all of the F. boothii isolates had the 15-acetyldeoxynivalenol (15ADON) chemotype. The results of genetic diversity analysis based on nine variable number tandem repeat (VNTR) loci supported the hypothesis of genetic isolation between F. meridionale and F. boothii, and provided little evidence of geographic substructure among populations of the dominant pathogen species, F. meridionale. This is the first study to indicate that F. meridionale and F. boothii may play a substantial role in the infection and trichothecene contamination of maize in Argentina. In addition, dominance of the NIV chemotype among Fg complex isolates from Argentina is unprecedented, and of significant concern to food safety and animal production. (C) 2010 Elsevier B.V.

AB We describe the odorant binding proteins (OBPs) of the red imported fire ant, Solenopsis invicta, obtained from analyses of an EST library and separate 454 sequencing runs of two normalized cDNA libraries. We identified a total of 18 putative functional OBPs in this ant. A third of the fire ant OBPs are orthologs to honey bee OBPs. Another third of the OBPs belong to a lineage-specific expansion, which is a common feature of insect OBP evolution. Like other OBPs, the different fire ant OBPs share little sequence similarity (similar to 20%), rendering evolutionary analyses difficult. We discuss the resulting problems with sequence alignment, phylogenetic analysis, and tests of selection. As previously suggested, our results underscore the importance for careful exploration of the sensitivity to the effects of alignment methods for data comprising widely divergent sequences.

AB Theoretical models indicate that trade-offs between growth and survival strategies of tree species can lead to coexistence across life history stages (ontogeny) and physical conditions experienced by individuals. There exist predicted physiological mechanisms regulating these trade-offs, such as an investment in leaf characters that may increase survival in stressful environments at the expense of investment in bole or root growth. Confirming these mechanisms, however, requires that potential environmental, ontogenetic, and trait influences are analyzed together. Here, we infer growth and mortality of tree species given size, site, and light characteristics from forest inventory data from Wisconsin to test hypotheses about growth-survival trade-offs given species functional trait values under different ontogenetic and environmental states. A series of regression analyses including traits and rates their interactions with environmental and ontogenetic stages supported the relationships between traits and vital rates expected from the expectations from tree physiology. A combined model including interactions between all variables indicated that relationships between demographic rates and functional traits supports growth-survival trade-offs and their differences across species in high-dimensional niche space. The combined model explained 65% of the variation in tree growth and supports a concept of community coexistence similar to Hutchinson's n-dimensional hypervolume and not a low-dimensional niche model or neutral model.

AB Non-lethal alternatives are needed to manage bird damage to confectionery and oilseed sunflower crops (Helianthus annuus). Ring-necked pheasants (Phasianus colchicus) can cause localized damage to newly planted sunflower, and blackbirds (Icterids) damage ripening sunflower annually in the United States of America. We conducted seed germination experiments, a repellent efficacy study with ring-necked pheasants and Avipel (R) repellent (a.i. 50% 9,10-anthraquinone), and laboratory and field efficacy studies with common grackles (Quiscalus quiscula) and Avipel (R)-treated confectionery sunflower. Compared to the germination of seeds not treated with anthraquinone, we observed no negative effects of up to 12,223 ppm, 14,104 ppm, and 11,569 ppm anthraquinone seed treatments for germination of confectionery sunflower, oilseed sunflower, and canola seeds, respectively. Pheasants avoided emergent sunflower seedlings (12 days post-planting) from 15,800 ppm anthraquinone seed treatments during a caged preference test (P = 0.045). We observed a positive concentration-response relationship (P = 0.001) and predicted a threshold concentration (i.e., 80% repellency) of 9200 ppm anthraquinone for common grackles offered Avipel (R)-treated confectionery sunflower seeds. Grackles also reliably discriminated between untreated sunflower and seeds treated with 1300 ppm anthraquinone in captivity (P < 0.001). During our field efficacy study for ripening confectionery sunflower, we observed 18% damage among anthraquinone-treated enclosures and 64% damage among untreated enclosures populated with common grackles (P < 0.001). Harvested seed mass averaged 2.54 kg (dry weight) among treated enclosures and 1.24 kg among untreated enclosures (P < 0.001). Our laboratory and field efficacy data provide a reliable basis for planning future field applications of anthraquinone-based repellents for protection of sunflower crops. Supplemental field efficacy studies are necessary for development of an effective avian repellent and management of avian depredation of ripening agricultural crops, including oilseed sunflower.

AB No-till dryland winter wheat (Triticum aestivum L)-fallow systems in the central Great Plains have more water available for crop production than the traditional conventionally tilled winter wheat-fallow systems because of greater precipitation storage efficiency. That additional water is used most efficiently when a crop is present to transpire the water, and crop yields respond positively to increases in available soil water. The objective of this study was to evaluate yield, water use efficiency (WUE), precipitation use efficiency (PUE), and net returns of cropping systems where crop choice was based on established crop responses to water use while incorporating a grass/broadleaf rotation. Available soil water at planting was measured at several decision points each year and combined with three levels of expected growing season precipitation (70, 100, 130% of average) to provide input data for water use/yield production functions for seven grain crops and three forage crops. The predicted yields from those production functions were compared against established yield thresholds for each crop, and crops were retained for further consideration if the threshold yield was exceeded. Crop choice was then narrowed by following a rule which rotated summer crops (crops planted in the spring with most of their growth occurring during summer months) with winter crops (crops planted in the fall with most of their growth occurring during the next spring) and also rotating grasses with broadleaf crops. Yields, WUE, PUE, value-basis precipitation use efficiency ($PUE), gross receipts, and net returns from the four opportunity cropping (OC) selection schemes were compared with the same quantities from four set rotations [wheat-fallow (conventional till), (WE (CT)); wheat-fallow (no-till), (WF (NT)); wheat-corn (Zen mays L)-fallow (no-till), (WCF); wheat-millet (Panicum miliaceum L) (no-till), (WM)]. Water use efficiency was greater for three of the OC selection schemes than for any of the four set rotations. Precipitation was used more efficiently using two of the OC selection schemes than using any of the four set rotations. Of the four OC cropping decision methods, net returns were greatest for the method that assumed average growing season precipitation and allowed selection from all possible crop choices. The net returns from this system were not different from net returns from WE (CT) and WF (NT). Cropping frequency can be effectively increased in dryland cropping systems by use of crop selection rules based on water use/yield production functions, measured available soil water, and expected precipitation.

AB Sophorolipids (SLs) are known to possess antimicrobial properties towards many species (particularly Gram-positive, or Gram(+)) of bacteria. However, these properties can only be exerted if the SLs can be introduced to the bacterial cells in an acceptable manner. Propionibacterium acnes is the common bacterial cause of acne. It is a Gram(+) facultative anaerobe that is susceptible to the antimicrobial effects of SLs. In this study we demonstrated that different biopolymer matrices could be used to produce SL composite films that exert various antimicrobial efficiencies against P. acnes. Increasing SL concentrations in poly-3-hydroxybutyrate (PHB) and PHB-co-10%-3-hydroxyhexanoate (PHB/HHx) resulted in noticeably improved (PHB/HHx was best) antimicrobial activity based on the size of the zones of inhibition using an overlay plating technique on synthetic growth medium. However, increasing concentrations of SLs in PHB and PHB/HHx films also increased film opacity, which diminishes the appeal for use especially in visible (facial) areas. Pectin and alginate improved the transparent character of SL composite films while also acting as successful carriers of SLs to P. acnes. The lactone form of the SLs proved to exhibit the best antimicrobial action and in concert with either pectin or alginate biopolymers provided a comparatively transparent, successful means of utilizing SLs as a renewable, environmentally benign anti-acne solution.

AB Switchgrass (Panicum virgatum) is a perennial, warm-season grass that has been identified as a potential biofuel feedstock over a large part of North America. We examined above- and belowground responses to nitrogen fertilization in "Alamo" switchgrass grown in West Tennessee, USA. The fertilizer study included a spring and fall sampling of 5-year old switchgrass grown under annual applications of 0, 67, and 202 kg N ha(-1) (as ammonium nitrate). Fertilization changed switchgrass biomass allocation as indicated by root: shoot ratios. End-of-growing season root:shoot ratios (mean +/- SE) declined significantly (P <= 0.05) at the highest fertilizer nitrogen treatment (2.16 +/- 0.08, 2.02 +/- 0.18, and 0.88 +/- 0.14, respectively, at 0, 67, and 202 kg N ha(-1)). Fertilization also significantly increased above- and belowground nitrogen concentrations and decreased plant C:N ratios. Data are presented for coarse live roots, fine live roots, coarse dead roots, fine dead roots, and rhizomes. At the end of the growing season, there was more carbon and nitrogen stored in belowground biomass than aboveground biomass. Fertilization impacted switchgrass tissue chemistry and biomass allocation in ways that potentially impact soil carbon cycle processes and soil carbon storage. (C) 2010 Elsevier B.V.

AB Gas chromatographic (GC) profiles of cuticular hydrocarbon extracts obtained from individual and pooled ant samples were analyzed using pattern recognition techniques. Clustering according to the biological variables of social caste and colony were observed. Pooling individual extracts enhanced the recognition of patterns in the GC profile data characteristic of colony. Evidently, the contribution of the ant's individual pattern to the overall hydrocarbon profile pattern can obscure information about colony in the GC traces of cuticular hydrocarbon extracts obtained from red fire ants. Re-analysis of temporal caste and time period data on the cuticular hydrocarbon patterns demonstrates that sampling time and social caste must be taken into account to avoid unnecessary variability and possible confounding. This and the fact that foragers could not be separated from reserves and brood-tenders in all five laboratory colonies studied suggests that cuticular hydrocarbons as a class of sociochemicals cannot model every facet of nestmate recognition in Solenopsis invicta which in turn suggests a potential role for other compounds in the discrimination of alien conspecifics from nestmates.

AB The Million Trees LA initiative intends to improve Los Angeles's environment through planting and stewardship of 1 million trees. The purpose of this study was to measure Los Angeles's existing tree canopy cover (TCC), determine if space exists for 1 million additional trees, and estimate future benefits from the planting. High-resolution QuickBird remote sensing data, aerial photographs, and geographic information systems were used to classify land cover types, measure TCC, and identify potential tree planting sites. Benefits were forecast for planting of 1 million trees between 2006 and 2010, and their growth and mortality were projected until 2040. Two scenarios reflected low (17%) and high (56%) mortality rates. Numerical models were used with geographic data and tree size information for coastal and inland climate zones to calculate annual benefits and their monetary value. Los Angeles's existing TCC was 21%, and ranged from 7 to 37% by council district. There was potential to add 2.5 million additional trees to the existing population of approximately 10.8 million, but only 1.3 million of the potential tree sites are deemed realistic to plant. Benefits for the 1-million-tree planting for the 35-year period were $1.33 billion and $1.95 billion for the high- and low-mortality scenarios, respectively. Average annual benefits were $38 and $56 per tree planted. Eighty-one percent of total benefits were aesthetic/other, 8% were stormwater runoff reduction, 6% energy savings, 4% air quality improvement, and less than 1% atmospheric carbon reduction.

DT Article
ID QUANTITATIVE TRAIT LOCI; ARABIDOPSIS-THALIANA; GENOME; IDENTIFICATION;
ASSOCIATION; MARKERS
AB Bulk segregant analysis (BSA) using microarrays, and extreme array mapping (XAM) have recently been used to rapidly identify genomic regions associated with phenotypes in multiple species. These experiments, however, require the identification of single feature polymorphisms (SFP) between the cross parents for each new combination of genotypes, which raises the cost of experiments. The availability of the genomic polymorphism data in Arabidopsis thaliana, coupled with the efficient designs of Single Nucleotide Polymorphism (SNP) genotyping arrays removes the requirement for SFP detection and lowers the per array cost, thereby lowering the overall cost per experiment. To demonstrate that these approaches would be functional on SNP arrays and determine confidence intervals, we analyzed hybridizations of natural accessions to the Arabidopsis ATSNPTILE array and simulated BSA or XAM given a variety of gene models, populations, and bulk selection parameters. Our results show a striking degree of correlation between the genotyping output of both methods, which suggests that the benefit of SFP genotyping in context of BSA can be had with the cheaper, more efficient SNP arrays. As a final proof of concept, we hybridized the DNA from bulks of an F2 mapping population of a Sulfur and Selenium ionomics mutant to both the Arabidopsis ATTILE1R and ATSNPTILE arrays, which produced almost identical results. We have produced R scripts that prompt the user for the required parameters and perform the BSA analysis using the ATSNPTILE1 array and have provided them as supplemental data files.

TI Elevated CO2 and warming effects on CH4 uptake in a semiarid grassland

AB Semiarid rangelands are a significant global sink for methane (CH4), but this sink strength may be altered by climate change. Methane uptake is sensitive to soil moisture showing a hump-shaped relationship with a distinct optimum soil moisture level. Both CO2 and temperature affect soil moisture, but the direction of CH4 uptake response may depend on if the system is below or above the soil moisture optimum. Most climate change studies on CH4 uptake have been conducted in mesic environments with soil moisture levels typically above optimum, but little is known about responses in drier systems with suboptimal soil water. We studied effects of atmospheric CO2 (ambient versus 600 ppm), and temperature (ambient versus 1.5/3.0 degrees C warmer day/night) on CH4 uptake during two growing seasons in a full factorial semiarid grassland field experiment in Wyoming, United States. We observed typical hump-shaped relationships between CH4 uptake and water filled pore space. Averaged over a range of soil moisture conditions, CH4 uptake was not affected by elevated CO2, but significantly decreased with warming in both seasons (25% in the first and 13% in the second season). Warming showed the strongest reduction and elevated CO2 showed the strongest increase in CH4 uptake when soils were below optimum moisture, indicating that these effects are particularly strong when soils are dry. Thus, directional effects of elevated CO2 and warming on CH4 uptake in semiarid grasslands can be opposite to their effects in mesic ecosystems because semiarid grasslands are often below optimum soil moisture for methane uptake.

AB Background: Genetic markers are pivotal to modern genomics research; however, discovery and genotyping of molecular markers in oat has been hindered by the size and complexity of the genome, and by a scarcity of sequence data. The purpose of this study was to generate oat expressed sequence tag (EST) information, develop a bioinformatics pipeline for SNP discovery, and establish a method for rapid, cost-effective, and straightforward genotyping of SNP markers in complex polyploid genomes such as oat.
Results: Based on cDNA libraries of four cultivated oat genotypes, approximately 127,000 contigs were assembled from approximately one million Roche 454 sequence reads. Contigs were filtered through a novel bioinformatics pipeline to eliminate ambiguous polymorphism caused by subgenome homology, and 96 in silico SNPs were selected from 9,448 candidate loci for validation using high-resolution melting (HRM) analysis. Of these, 52 (54%) were polymorphic between parents of the Ogle1040 x TAM O-301 (OT) mapping population, with 48 segregating as single Mendelian loci, and 44 being placed on the existing OT linkage map. Ogle and TAM amplicons from 12 primers were sequenced for SNP validation, revealing complex polymorphism in seven amplicons but general sequence conservation within SNP loci. Whole-amplicon interrogation with HRM revealed insertions, deletions, and heterozygotes in secondary oat germplasm pools, generating multiple alleles at some primer targets. To validate marker utility, 36 SNP assays were used to evaluate the genetic diversity of 34 diverse oat genotypes. Dendrogram clusters corresponded generally to known genome composition and genetic ancestry.
Conclusions: The high-throughput SNP discovery pipeline presented here is a rapid and effective method for identification of polymorphic SNP alleles in the oat genome. The current-generation HRM system is a simple and highly-informative platform for SNP genotyping. These techniques provide a model for SNP discovery and genotyping in other species with complex and poorly-characterized genomes.

AB Cinnamyl alcohol dehydrogenase (CAD) catalyzes the last step in monolignol biosynthesis and genetic evidence indicates CAD deficiency in grasses both decreases overall lignin, alters lignin structure and increases enzymatic recovery of sugars. To ascertain the effect of CAD downregulation in switchgrass, RNA mediated silencing of CAD was induced through Agrobacterium mediated transformation of cv. "Alamo'' with an inverted repeat construct containing a fragment derived from the coding sequence of PviCAD2. The resulting primary transformants accumulated less CAD RNA transcript and protein than control transformants and were demonstrated to be stably transformed with between 1 and 5 copies of the TDNA. CAD activity against coniferaldehyde, and sinapaldehyde in stems of silenced lines was significantly reduced as was overall lignin and cutin. Glucose release from ground samples pretreated with ammonium hydroxide and digested with cellulases was greater than in control transformants. When stained with the lignin and cutin specific stain phloroglucinol-HCl the staining intensity of one line indicated greater incorporation of hydroxycinnamyl aldehydes in the lignin.

OUTBRED PEDIGREE; CONSTRUCTION; SEQUENCE; INTEGRATION; PINACEAE
AB Background: Previous loblolly pine (Pinus taeda L.) genetic linkage maps have been based on a variety of DNA polymorphisms, such as AFLPs, RAPDs, RFLPs, and ESTPs, but only a few SSRs (simple sequence repeats), also known as simple tandem repeats or microsatellites, have been mapped in P. taeda. The objective of this study was to integrate a large set of SSR markers from a variety of sources and published cDNA markers into a composite P. taeda genetic map constructed from two reference mapping pedigrees. A dense genetic map that incorporates SSR loci will benefit complete pine genome sequencing, pine population genetics studies, and pine breeding programs. Careful marker annotation using a variety of references further enhances the utility of the integrated SSR map.
Results: The updated P. taeda genetic map, with an estimated genome coverage of 1,515 cM((Kosambi)) across 12 linkage groups, incorporated 170 new SSR markers and 290 previously reported SSR, RFLP, and ESTP markers. The average marker interval was 3.1 cM. Of 233 mapped SSR loci, 84 were from cDNA-derived sequences (EST-SSRs) and 149 were from non-transcribed genomic sequences (genomic-SSRs). Of all 311 mapped cDNA-derived markers, 77% were associated with NCBI Pta UniGene clusters, 67% with RefSeq proteins, and 62% with functional Gene Ontology (GO) terms. Duplicate (i.e., redundant accessory) and paralogous markers were tentatively identified by evaluating marker sequences by their UniGene cluster IDs, clone IDs, and relative map positions. The average gene diversity, H-e, among polymorphic SSR loci, including those that were not mapped, was 0.43 for 94 EST-SSRs and 0.72 for 83 genomic-SSRs. The genetic map can be viewed and queried at http://www.conifergdb.org/pinemap.
Conclusions: Many polymorphic and genetically mapped SSR markers are now available for use in P. taeda population genetics, studies of adaptive traits, and various germplasm management applications. Annotating mapped genes with UniGene clusters and GO terms allowed assessment of redundant and paralogous EST markers and further improved the quality and utility of the genetic map for P. taeda.

AB Metolachlor (2-chloro-6'-ethyl-N-(2-methoxy-1-methylethyl)aceto-o-toluidide) is a pre-emergent chloroacetanilide herbicide used to control broadleaf and annual grassy weeds in a variety of crops. The S enantiomer, S-metolachlor, is the most effective form for weed control. Although the degradation of metolachlor in soils is thought to occur primarily by microbial activity, little is known about the microorganisms that carry out this process and the mechanisms by which this occurs. This study examined a silty-clay soil (a Luvisol) from Spain, with 10 and 2 year histories of metolachlor and S-metolachlor applications, respectively, for microorganisms that had the ability to degrade this herbicide. Tis paper reports the isolation and characterization of pure cultures of Candida xestobii and Bacillus simplex that have the ability to use metolachlor as a sole source of carbon for growth. Species assignment was confirmed by morphological and biochemical criteria and by sequence analysis of 18S and 16S rRNA, respectively. High-performance liquid chromatography (HPLC) and liquid chromatography-mass spectrometry (LC-MS) analyses indicated that C. xestobii degraded 60% of the added metolachlor after 4 days of growth and converted up to 25% of the compound into CO2 after 10 days. In contrast, B. simplex biodegraded 30% of metolachlor following 5 days of growth in minimal medium. In contrast, moreover, the yeast degraded other acetanilide compounds and 80% of acetochlor (2-chloro-N-ethoxymethyl-6'-ethylaceto-o-toluidide) and alachlor (2-chloro-2',6'-diethyl-N-methoxymethylacetanilide) were degraded after 15 and 41 h of growth, respectively. The results of these studies indicate that microorganisms comprising two main branches of the tree of life have acquired the ability to degrade the same novel chlorinated herbicide that has been recently added to the biosphere.

AB Hydroxypropyl methylcellulose (HPMC) is a substituted cellulose that reduces serum cholesterol at modest intake levels. HPMC has also been used for decades in gluten-free breads at a level to optimize loaf volume. Because consumers resist the consumption of whole wheat breads, the sensory and physical properties of all oat and barley breads incorporating HPMC were evaluated. Oat and barley also contain beta-glucan, a glucose polymer similar to HPMC that also lowers cholesterol. The textural and sensory properties of the breads were determined by instrumental and chemical methods and sensory panels. HPMC increased the loaf volume of the breads by up to 2 times and decreased hardness immediately after baking and after up to 3 days of storage. Barley bread with HPMC was rated the highest in overall acceptability by sensory panelists compared to oat and wheat breads with or without HPMC.

AB Background: Obesity is a hallmark of aging in many Western societies, and is a precursor to numerous serious age-related diseases. Ghrelin (Ghrl), via its receptor (growth hormone secretagogue receptor, GHS-R), is shown to stimulate GH secretion and appetite. Surprisingly, our previous studies showed that Ghrl(-/-) mice have impaired thermoregulatory responses to cold and fasting stresses, while Ghsr(-/-) mice are adaptive.
Methodology/Principal Findings: To elucidate the mechanism, we analyzed the complete metabolic profiles of younger (3-4 months) and older (10-12 months) Ghrl(-/-) and Ghsr(-/-) mice. Food intake and locomotor activity were comparable for both null mice and their wild-type (WT) counterparts, regardless of age. There was also no difference in body composition between younger null mice and their WT counterparts. As the WT mice aged, as expected, the fat/lean ratio increased and energy expenditure (EE) decreased. Remarkably, however, older Ghsr(-/-) mice exhibited reduced fat/lean ratio and increased EE when compared to older WT mice, thus retaining a youthful lean and high EE phenotype; in comparison, there was no significant difference with EE in Ghrl(-/-) mice. In line with the EE data, the thermogenic regulator, uncoupling protein 1 (UCP1), was significantly up-regulated in brown adipose tissue (BAT) of Ghsr(-/-) mice, but not in Ghrl(-/-) mice.
Conclusions: Our data therefore suggest that GHS-R ablation activates adaptive thermogenic function(s) in BAT and increases EE, thereby enabling the retention of a lean phenotype. This is the first direct evidence that the ghrelin signaling pathway regulates fat-burning BAT to affect energy balance during aging. This regulation is likely mediated through an as-yet-unidentified new ligand of GHS-R.

TI Annotation-based genome-wide SNP discovery in the large and complex
Aegilops tauschii genome using next-generation sequencing without a

AB Background: Many plants have large and complex genomes with an abundance of repeated sequences. Many plants are also polyploid. Both of these attributes typify the genome architecture in the tribe Triticeae, whose members include economically important wheat, rye and barley. Large genome sizes, an abundance of repeated sequences, and polyploidy present challenges to genome-wide SNP discovery using next-generation sequencing (NGS) of total genomic DNA by making alignment and clustering of short reads generated by the NGS platforms difficult, particularly in the absence of a reference genome sequence.
Results: An annotation-based, genome-wide SNP discovery pipeline is reported using NGS data for large and complex genomes without a reference genome sequence. Roche 454 shotgun reads with low genome coverage of one genotype are annotated in order to distinguish single-copy sequences and repeat junctions from repetitive sequences and sequences shared by paralogous genes. Multiple genome equivalents of shotgun reads of another genotype generated with SOLiD or Solexa are then mapped to the annotated Roche 454 reads to identify putative SNPs. A pipeline program package, AGSNP, was developed and used for genome-wide SNP discovery in Aegilops tauschii-the diploid source of the wheat D genome, and with a genome size of 4.02 Gb, of which 90% is repetitive sequences. Genomic DNA of Ae. tauschii accession AL8/78 was sequenced with the Roche 454 NGS platform. Genomic DNA and cDNA of Ae. tauschii accession AS75 was sequenced primarily with SOLiD, although some Solexa and Roche 454 genomic sequences were also generated. A total of 195,631 putative SNPs were discovered in gene sequences, 155,580 putative SNPs were discovered in uncharacterized single-copy regions, and another 145,907 putative SNPs were discovered in repeat junctions. These SNPs were dispersed across the entire Ae. tauschii genome. To assess the false positive SNP discovery rate, DNA containing putative SNPs was amplified by PCR from AL8/78 and AS75 and resequenced with the ABI 3730 xl. In a sample of 302 randomly selected putative SNPs, 84.0% in gene regions, 88.0% in repeat junctions, and 81.3% in uncharacterized regions were validated.
Conclusion: An annotation-based genome-wide SNP discovery pipeline for NGS platforms was developed. The pipeline is suitable for SNP discovery in genomic libraries of complex genomes and does not require a reference genome sequence. The pipeline is applicable to all current NGS platforms, provided that at least one such platform generates relatively long reads. The pipeline package, AGSNP, and the discovered 497,118 Ae. tauschii SNPs can be accessed at (http://avena.pw.usda.gov/wheatD/agsnp.shtml).

AB The Japanese beetle (JB), Popillia japonica, exhibits rapid paralysis after consuming flower petals of zonal geranium, Pelargonium x hortorum. Activity-guided fractionations were conducted with polar flower petal extracts from P. x hortorum cv. Nittany Lion Red, which led to the isolation of a paralysis-inducing compound. High-resolution-MSandNMR ((1)H, (13)C, COSY, heteronuclear sequential quantum correlation, heteronuclear multiple bond correlation) analysis identified the paralytic compound as quisqualic acid (C(5)H(7)N(3)O(5)), a known but rare agonist of excitatory amino acid receptors. Optical rotation measurements and chiral HPLC analysis determined an L-configuration. Geranium-derived and synthetic L-quisqualic acid demonstrated the same positive paralytic dose-response. Isolation of a neurotoxic, excitatory amino acid from zonal geranium establishes the phytochemical basis for induced paralysis of the JB, which had remained uncharacterized since the phenomenon was first described in 1920.

AB As part of efforts to identify native herbivores of Mexican palo verde, Parkinsonia aculeata L. (Leguminosae: Caesalpinioideae), as potential biological control agents against this invasive weed in Australia, ten species of Tortricidae (Lepidoptera) were reared from Guatemala, Mexico, Nicaragua, and Venezuela: Amorbia concavana (Zeller), Platynota rostrana (Walker), Platynota helianthes (Meyrick), Platynota stultana Walsingham (all Tortricinae: Sparganothini), Rudenia leguminana (Busck), Cochylis sp. (both Tortricinae: Cochylini), Ofatulena duodecemstriata (Walsingham), O. luminosa Heinrich, Ofatulena sp. (all Olethreutinae: Grapholitini), and Crocidosema lantana Busck (Olethreutinae: Eucosmini). Significant geographic range extensions are provided for O. duodecemstriata and R. leguminana. These are the first documented records of P. aculeata as a host plant for all but O. luminosa. The four species of Sparganothini are polyphagous; in contrast, the two Cochylini and three Grapholitini likely are specialists on Leguminosae. Ofatulena luminosa is possibly host specific on P. aculeata. Host trials with Rudenia leguminana also provide some evidence of specificity, in contrast to historical rearing records. To examine the possibility that R. leguminana is a complex of species, two data sets of molecular markers were examined: (1) a combined data set of two mitochondrial markers (a 781-basepair region of cytochrome c oxidase I (COI) and a 685-basepair region of cytochrome c oxidase II) and one nuclear marker (a 531-basepair region of the 28S domain 2); and (2) the 650-basepair "barcode" region of COI. Analyses of both data sets strongly suggest that individuals examined in this study belong to more than one species.

AB Loblolly pine (LP; Pinus taeda L.) is the most economically important tree in the U. S. and a cornerstone species in southeastern forests. However, genomics research on LP and other conifers has lagged behind studies on flowering plants due, in part, to the large size of conifer genomes. As a means to accelerate conifer genome research, we constructed a BAC library for the LP genotype 7-56. The LP BAC library consists of 1,824,768 individually-archived clones making it the largest single BAC library constructed to date, has a mean insert size of 96 kb, and affords 7.6X coverage of the 21.7 Gb LP genome. To demonstrate the efficacy of the library in gene isolation, we screened macroarrays with overgos designed from a pine EST anchored on LP chromosome 10. A positive BAC was sequenced and found to contain the expected full-length target gene, several gene-like regions, and both known and novel repeats. Macroarray analysis using the retrotransposon IFG-7 (the most abundant repeat in the sequenced BAC) as a probe indicates that IFG-7 is found in roughly 210,557 copies and constitutes about 5.8% or 1.26 Gb of LP nuclear DNA; this DNA quantity is eight times the Arabidopsis genome. In addition to its use in genome characterization and gene isolation as demonstrated herein, the BAC library should hasten whole genome sequencing of LP via next-generation sequencing strategies/technologies and facilitate improvement of trees through molecular breeding and genetic engineering. The library and associated products are distributed by the Clemson University Genomics Institute (www.genome.clemson.edu).

AB Whole crop third cut alfalfa, brown mid-rib (bmr) corn, and corn were chopped and inoculated with one of four microbial inoculants used. Uninoculated silage was the control treatment. Each crop was ensiled in four mini-silos (1 L glass jars) per treatment. All silos were fermented for 60 days at room temperature (22 degrees C), and then they were opened and analyzed for fermentation products, fiber constituents and N fractions. A fraction of wet silage was ground with a blender for 30s. In vitro gas production was measured in 160 ml sealed serum vials at 3, 6, 9, 24, and 48 h using the wet ground silage. At 9 and 48 h, rumen fluid was analyzed for volatile fatty acids (VFA) and microbial biomass yield (MBY). In all the three crops, the four inoculants produced only minor changes in pH and fermentation products during ensiling. Of the variables measured, soluble nonprotein N fractions were the characteristics most often affected by some inoculants. At 9 h incubation, in vitro gas production and VFA did not differ between control and inoculated silages, but MBY did. Among crops, alfalfa and corn silages had higher MBY than did bmr corn silage. Among inoculants, three of the four inoculated silages produced more MBY than did control. At 48 h, alfalfa silage produced higher MBY than did corn or bmr silage, and two of the inoculated silages had more MBY than did the control. There was no inoculant by crop interaction. Results suggest that some silage inoculants are capable of altering rumen fermentation, even in cases where effects on silage fermentation are small, and that this effect may be linked to better preservation of crop protein during ensiling.

AB The effect of sulfide-modified corn oil (SMCO) and ditertiary dodecyl pentasulfide (PS) additives on the oxidative stability of corn oil (CO) and polyalphaolefin oil (PAO) was investigated using pressurized differential scanning calorimetry in dynamic (DDSC) and isothermal (IDSC) modes. DDSC showed a weak pro-oxidant effect of SMCO and PS in CO, and antioxidant behavior in PAO. Analysis of the IDSC data showed the existence of isokinetic temperature in both oils. Below the isokinetic temperature the sulfides behaved as antioxidants while above it they behaved as pro-oxidants. The isokinetic temperature was found to depend on the chemical structure of the oils. For the highly unsaturated CO, the isokinetic temperature was 100-135 degrees C. while for the fully saturated PAO it was above 200 C. The existence of isokinetic temperature provides consistent explanation to our and literature data for oxidation behaviors of sulfide additives in oils, which appears to be contradictory (pro-oxidant vs. antioxidant) depending on experimental conditions. The isokinetic temperature suggests that accelerated oxidation test methods at elevated temperatures are poor predictors of the low-temperature performance of sulfide-containing antioxidants.

AB Background: Metabolic reconstructions (MRs) are common denominators in systems biology and represent biochemical, genetic, and genomic (BiGG) knowledge-bases for target organisms by capturing currently available information in a consistent, structured manner. Salmonella enterica subspecies I serovar Typhimurium is a human pathogen, causes various diseases and its increasing antibiotic resistance poses a public health problem.
Results: Here, we describe a community-driven effort, in which more than 20 experts in S. Typhimurium biology and systems biology collaborated to reconcile and expand the S. Typhimurium BiGG knowledge-base. The consensus MR was obtained starting from two independently developed MRs for S. Typhimurium. Key results of this reconstruction jamboree include i) development and implementation of a community-based workflow for MR annotation and reconciliation; ii) incorporation of thermodynamic information; and iii) use of the consensus MR to identify potential multi-target drug therapy approaches.
Conclusion: Taken together, with the growing number of parallel MRs a structured, community-driven approach will be necessary to maximize quality while increasing adoption of MRs in experimental design and interpretation.

AB Heat waves are expected to become more frequent and severe as climate changes, with unknown consequences for biodiversity. We sought to identify ecologically-relevant broad-scale indicators of heat waves based on MODIS land surface temperature (LST) and interpolated air temperature data and assess their associations with avian community structure. Specifically, we asked which data source, time periods, and heat wave indices best predicted changes in avian abundance and species richness. Using mixed effects models, we analyzed associations between these indices and data from the North American Breeding Bird Survey in the central United States between 2000 and 2007 in four ecoregions and five migratory and nesting species groups. We then quantified avian responses to scenarios of severe, but commonly-occurring early, late, and summer-long heat waves. Indices based on MODIS LST data, rather than interpolated air temperatures, were more predictive of avian community structure. Avian communities were more related to 8-day LST exceedances (positive anomalies only); and were generally more sensitive to summer-long heat waves. Across the region, abundance, and to a lesser extent, species richness, declined following heat waves. Among the ecoregions, relationships were most consistently negative in the southern and montane ecoregions, but were positive in a more humid northern ecoregion. Among migratory groups, permanent resident species were the most sensitive, declining in abundance following a summer-long heat wave by 19% and 13% in the montane and southern ecoregions, respectively. Ground-nesting species, which declined in the south by 12% following a late summer heat wave, were more sensitive than avifauna overall. These results demonstrate the value of MODIS LST data for measuring ecologically-relevant heat waves across large regions. Ecologically, these findings highlight the importance of extreme events for avian biodiversity and the considerable variation in response to environmental change associated with different functional groups and geographic regions. The magnitude of the relationships between avian abundance and heat waves reported here raises concerns about the impacts of more frequent and severe heat waves in a warming climate.

AB The high oleic (C18:1) phenotype in peanuts has been previously demonstrated to result from a homozygous recessive genotype (ol(1)ol(1)ol(2)ol(2)) in two homeologous fatty acid desaturase genes (FAD2A and FAD2B) with two key SNPs. These mutant SNPs, specifically G448A in FAD2A and 442insA in FAD2B, significantly limit the normal function of the desaturase enzyme activity which converts oleic acid into linoleic acid by the addition of a second double bond in the hydrocarbon chain. Previously, a genotyping assay was developed to detect wild type and mutant alleles in FAD2B. A real-time PCR assay has now been developed to detect wild type and mutant alleles (G448A) in FAD2A using either seed or leaf tissue. This assay was demonstrated to be applicable for the detection of homozygous and heterozygous samples. The FAD2A genotyping assay was validated by employing gas chromatography (GC) to determine total fatty acid composition and by genotyping peanut lines that have been well characterized. Overall, development of rapid assays such as real-time PCR which can identify key genotypes associated with important agronomic traits such as oleic acid, will improve breeding efficiency by targeting desirable genotypes at early stages of development.

AB Stand-level growth responses and plant-level patterns of biomass accumulation and distribution were examined to learn how stand structure influences morphological acclimation and growth of green ash (Fraxinus pennsylvanica Marsh.) advance regeneration following overstory harvesting. Nine, 20-ha plots that received clearcut harvesting (100% basal area removal), partial harvesting (50% basal area removal), or no harvesting (control) were sampled to measure height, root-collar diameter, leaf, stem and root biomass, and leaf mass ratio (LMR), stem mass ratio (SMR) and root mass ratio (RMR) of ash regeneration. Six years after treatment, plot-level analyses indicated that ash growth was greatest in plots receiving clearcut harvesting, and least in control plots. Examination of LMR. SMR and RMR revealed that this growth response was not associated with acclimation that altered plant morphology. Total biomass ranged 275-fold among sampled plants, and much of this variation was accounted for by measurements of stand leaf area index (LAI). Along the gradient of stand LAI, values greater than 2 inhibited biomass accumulation. Stand LAI values less than 1.5 promoted ash biomass accumulation which reached a maximum where LAI values approached 0.7 and tapered above or below this value. Our findings indicate that green ash regeneration can be managed beneath light canopy cover, and the ability of seedlings to establish and persist beneath closed canopies and vigorously respond to release without having to endure prolonged morphological acclimation provides flexibility in developing regeneration protocols.

AB Nitrate (NO(3)(-1)) accumulates in Haplocambids and Torrifluvents in inset fan and fan skirt positions in central Nevada. The soils store as much as 17,600 kg of NO(3)(-1) N ha(-1) within the upper 208 cm. This paper provides an explanation. These Holocene soils receive NO(3)(-1) N from mineralization of organic matter and other NO(3)(-1)N sources including snowmelt. The NO(3)(-1) is delivered to soils in the first part of snowmelt in run-off from the higher surfaces. The last part of the melt and the run-off, when sufficient, serve to move the NO(3)(-1) out of the root zone. Winter fat (Krascheninnikovia lanata), the most valuable winter grazing plant in the Great Basin, is the common plant on NO(3)(-1) N rich soils. The soils are loamy or sandy and lack horizons restricting water penetration or biological denitrification zones. Hence, some NO(3)(-1) is free to leach deeply past plant roots. Playas, wet floodplains, deeply gullied inset fans and well-developed soils accumulate little NO(3)(-1) except where the latter soils are capped by desert pavements and rarely, if ever become saturated with water. Soils with argillic or petrocalcic horizons or duripans on summits of alluvial fan remnants loose NO(3)(-1) through denitrification, or incorporate it in plants, commonly accumulating less than 50 kg of NO(3)(-1) N ha(-1). These soils however do accumulate salt as shown by their shadscale saltbush Aniplex confertifolia, bud sagebrush Picrothamnus desertorum, and four-wing saltbush Atriplex conescens shrub cover.

AB The objective of this study was to evaluate the effects of geographical location, crop type, and residue coverage on soil microbial assemblages in Sherm soil from 30 geographically separate commercial fields in Ochiltree and Moore Counties of Texas. Crop residue coverage was derived from spectral data and used to classify sorghum and wheat fields into high and low crop residue categories. Denaturing gradient gel electrophoresis-polymerase chain reaction (DGGE-PCR) assays employing universal PCR primers that target prokaryotic and eukaryotic ribosomal genes were used to evaluate microbial community structure. An interaction between geographical location, crop type, and crop residue coverage was observed. A 50% similarity level was observed for overall bacterial community structure as determined using 16S data while a 59% similarity was observed for overall fungal community structure using 18S data. For the 16S composite dataset, high overall rates of correct classification (ORCC) were observed based on the user-defined groups of county by crop by residue coverage. A similar result was observed for fungal community structure using primer set FR1GC-FF390. Our data support the hypothesis that there are multiple provinces and multiple habitats that govern the assemblage of free-living taxa within the Moore-Ochiltree County agroecosystem. An ancient microbial assemblage based on historical features was identified and is still visible despite the presence of different crop types and cropping systems (Conventional vs. Conservation). For sorghum and wheat grown in Moore and Ochiltree Counties, a two-province state (Moore and Ochiltree Counties) was defined comprised of four habitats i.e. sorghum and wheat habitats influence by degree of residue coverage. Crop type and residue coverage can affect microbial assemblages within a geographical context. Published by Elsevier B.V.

AB Soil C and nutrient contents were estimated for eight watersheds in two sites (one high elevation, Bull, and one low elevation, Providence) in the Kings River Experimental Watersheds in the western Sierra Nevada Mountains of California. Eighty-seven quantitative pits were dug to measure soil bulk density and total rock content, while three replicate surface samples were taken nearby with a bucket auger (satellite samples) to the same depth as surface pit samples. Results showed that the higher elevation Bull watersheds had significantly greater C, N, and B contents and significantly lower extractable P. exchangeable Ca(2+). Mg(2+), and Na(+) contents (kg ha(-1)) and lower pH than the lower elevation Providence watersheds. Soil NH(4)(+) and mineral N contents were high in both the Bull and Providence watersheds and could not be related to any measured soil property or attributed to known rates of atmospheric deposition. Nutrient analyses on satellite samples were comparable to those taken from pits when averaged on a watershed or site (Bull and Providence) scale, but quite variable on an individual grid point basis. Elevated Zn values from the quantitative pit samples suggested contamination by field sieving through a galvanized screen. Had the amount of large rocks within the soil sample not been accounted for with quantitative pit analyses, estimates of fine earth and associated C and nutrient contents (kg ha(-1)) would have been overestimated by 16 to 43%.

AB More accurate projections of future carbon dioxide concentrations in the atmosphere and associated climate change depend on improved scientific understanding of the terrestrial carbon cycle. Despite the consensus that U.S. terrestrial ecosystems provide a carbon sink, the size, distribution, and interannual variability of this sink remain uncertain. Here we report a terrestrial carbon sink in the conterminous U.S. at 0.63 pg C yr(-1) with the majority of the sink in regions dominated by evergreen and deciduous forests and savannas. This estimate is based on our continuous estimates of net ecosystem carbon exchange (NEE) with high spatial (1 km) and temporal (8-day) resolutions derived from NEE measurements from eddy covariance flux towers and wall-to-wall satellite observations from Moderate Resolution Imaging Spectroradiometer (MODIS). We find that the U.S. terrestrial ecosystems could offset a maximum of 40% of the fossil-fuel carbon emissions Our results show that the U.S. terrestrial carbon sink varied between 0.51 and 0.70 pg C yr(-1) over the period 2001-2006. The dominant sources of interannual variation of the carbon sink Included extreme climate events and disturbances. Droughts in 2002 and 2006 reduced the U.S. carbon sink by similar to 20% relative to a normal year. Disturbances including wildfires and hurricanes reduced carbon uptake or resulted in carbon release at regional scales. Our results provide an alternative, independent, and novel constraint to the U.S. terrestrial carbon sink. (C) 2010 Elsevier B.V. All rights reserved

AB In this study, a novel immunoassay using 2 types of sensors (QDs and an enzyme) were simultaneously used for detecting multiple structurally different molecules in milk. The method integrates the fluorescence-linked immunosorbent assay (FLISA) using QD605 and QD655 as probes and an enzyme-linked immunosorbent assay (ELISA) using horseradish peroxidase (HRP) labeled secondary antibody. The FLISA was produced by anti-sulfonamide and anti-quinolone broad-specificity monoclonal antibodies (MAbs) for simultaneously detecting 6 sulfonamides and 11 quinolones. Combined with the FLISA, an ELISA was utilized for detecting melamine from the same milk samples. The cross-reactivity of the MAbs was retained while binding the QDs by using avidin and a secondary antibody as bridges. Milk samples were detected using this hybrid immunoassay, with limits of detection CLOD) of the quinolones (0.18 ng mL(-1)), sulfonamides (0.17 ng mL(-1)) and melamine (7.5 ng mL(-1)), respectively. The results demonstrated that the detection limits of the integrated methods were better than required and simplified the sample pretreatment process. The developed immunoassay is suitable for high-throughput screening of low-molecular weight contaminants. (c) 2010 Elsevier B.V. All rights reserved.

AB Hydrogen production by methane decomposition and catalytic partial oxidation of methane (CPOM) over Pt/(Ce0.91Gd0.09)O-2 (-) (x) and Pr/(Ce0.56Zr0.44)O2 - x were studied. Results show that during the methane decomposition tests, in the absence of gaseous oxygen, hydrogen and CO were the main products and very small quantities of CO2 were recorded. The generation of these products lasted for about 2 h, indicating that in the catalytic stability of these materials, the carrier plays an important factor. The addition of Gd and Zr cations to ceria had a positive effect on the catalysts stability. Regarding the catalytic partial oxidation of methane, a stable hydrogen production was recorded for 20 h. Here, it is proposed that the formation of a Pt-O-Ce bond causes high stability of Pt in Ce-containing supports under oxidizing conditions at high temperatures because this bond may act as an anchor, inhibiting the sintering of Pt. The deposited carbon during the catalytic tests was oxidized and the CO2 profiles showed a sharper peak appearing at a lower temperature and a broader peak at the higher temperature. The first peak may correspond to the oxidation of coke on and in the vicinity of the metal and the second CO2 peak may represent the coke on the carrier. The CPOM as a function of O/C ratio was studied. It was observed that the catalyst with a higher ionic conductivity, Pt/(Ce0.91Gd0.09)O-2 (-) (x), generated a lower amount of deposited carbon.

AB Rice (Oryza sativa L) is enjoyed by many people as a staple food because of its flavour and texture. Some cultivars, like scented rice, are preferred over others due to their distinctive aroma and flavour. The volatile profile of rice has been explored by other investigators, some of whom have also determined a corresponding aroma using GC/olfactometry. However, little research has been done to determine if different aromatic rice cultivars produce different flavour volatiles that would make them more desirable than others when cooked. In this study, seven aromatic and two non-aromatic cultivars were examined for their volatile profiles both before and after storage using solid phase microextraction (SPME) fibres in conjunction with gas chromatography/mass spectrometer (GC-MS). Ninety-three volatile compounds were identified, 64 of which had not been previously reported in rice. Differences were found in the volatile compounds of aromatic and non-aromatic rice besides 2-acetyl-1-pyrroline (2-AP). Most of the volatile compounds were present in freshly harvested rice and rice following storage, with very few new compounds being identified only after storage. Dellrose, an aromatic cultivar, and Cocodrie, a non-aromatic cultivar, had the most complex volatile profiles (over 64 volatiles). Sixteen compounds were found only in the aromatic cultivars, and some volatiles were found to be unique to specific aromatic cultivars. However, no distinctive pattern was observed that would identify a cultivar as being derived from Basmati, Khao Dawk Mali 105 (i.e. jasmine), or other sources of aroma. This study showed that there is a great diversity of volatiles in both aromatic and non-aromatic rice cultivars and, with further research, this may lead to a better understanding of the combination of compounds that gives a cultivar a unique flavour.

AB Alzheimer disease elevates lipid peroxidation in the brain and data indicate that the resulting lipid-aldehydes are pathological effectors of lipid peroxidation. The disposition of 4-substituted nonenals derived from arachidonate (20:4, n-6) and linoleate (18:2, n-6) oxidation is modulated by their protein adduction targets, their metabolism, and the nature of the 4-substitutent. Trans-4-oxo-2-nonenal (4-ONE) has a higher toxicity in some systems than the more commonly studied trans-4-hydroxy-2-nonenal (HNE). In this work, we performed a structure-function analysis of 4-hydroxy/oxoalkenal upon mitochondrial endpoints. We tested the hypotheses that 4-ONE, owing to a highly reactive nature, is more toxic than HNE and that HNE toxicity is enantioselective. We chose to study freshly isolated brain mitochondria because of the role of mitochondrial dysfunction in neurodegenerative disorders. Whereas there was little effect related to HNE chirality, our data indicate that in the mitochondrial environment, the order of toxic potency under most conditions was 4-ONE> HNE. 4-ONE uncoupled mitochondrial respiration at a concentration of 5 mu M and inhibited aldehyde dehydrogenase 2 (ALDH2) activity with an IC(50) of approximately 0.5 mu M. The efficacy of altering mitochondrial endpoints was ALDH2 inhibition>respiration = mitochondrial swelling = ALDH5A inhibition>GSH depletion. Thiol-based alkenal scavengers, but not amine-based scavengers, were effective in blocking the effects of 4-ONE upon respiration. Quantum mechanical calculations provided insights into the basis for the elevated reactivity of 4-ONE> HNE. Our data demonstrate that 4-ONE is a potent effector of lipid peroxidation in the mitochondrial environment. Published by Elsevier Inc.

AB Phytoremediation is a cost-effective and minimally invasive technology to cleanse soils contaminated with heavy metals. However, few plant species are suitable for phytoremediation of metals such as cadmium (Cd). Genetic engineering offers a powerful tool to generate plants that can hyperaccumulate Cd. An Arabidopsis CAX1 mutant (CAXcd), which confers enhanced Cd transport in yeast, was ectopically expressed in petunia to evaluate whether the CAXcd expression would enhance Cd tolerance and accumulation in planta. The CAXcd-expressing petunia plants showed significantly greater Cd tolerance and accumulation than the controls. After being treated with either 50 or 100 mu M CdCl2 for 6 weeks, the CAXcd-expressing plants showed more vigorous growth compared with controls, and the transgenic plants accumulated significantly more Cd (up to 2.5-fold) than controls. Moreover, the accumulation of Cd did not affect the development and morphology of the CAXcd-expressing petunia plants until the flowering and ultimately the maturing of seeds. Therefore, petunia has the potential to serve as a model species for developing herbaceous, ornamental plants for phytoremediation. (C) 2010 Elsevier GmbH. All rights reserved.

AB At the onset of puberty, serniniferous tubules rapidly increase in diameter, thereby occupying a greater proportion of the testis, resulting in a rapid increase in testicular size. The objective of the current studies was to evaluate ultrasonography for assessing testicular diameter, as a basis for ranking boars relative to their extent of pubertal development. In the initial study, prior to castration at 4, 5, 6, or 7 mo of age, testicular length and diameter were assessed by ultrasonography in 160 anesthetized boars. After castration, testes were weighed. Mean diameter of seminiferous tubules and percentage of the testis occupied by tubules were determined by histological evaluations of all testes. Testicular volume was calculated from length and diameter and was correlated with testicular weight (P < 0.001; r >= 0.78) within each of the four age groups. At 4 and 5 mo of age, testicular diameter correlated positively (P < 0.001) with diameter of seminiferous tubules; this relationship was not significant at older ages. In two subsequent studies, testicular diameter determined ultrasonographically in conscious boars was highly correlated (r > 0.8) when assessed twice on the same day, or when diameter of the right was compared with diameter of the left testis. Similarly, testicular diameter obtained initially at 92 d of age correlated positively (P < 0.001) with the diameter observed at older ages, but the magnitude of the relationship decreased as time between evaluations increased. These findings supported ultrasonographic determination of testicular diameter during early pubertal development, as a means to rank boars of similar chronological age for extent of pubertal development.

AB An active crop canopy reflectance sensor could be used to increase N-use efficiency in maize (Zea mays L.), if temporal and spatial variability in soil N availability and plant demand are adequately accounted for with an in-season N application. Our objective was to evaluate the success of using an active canopy sensor for developing maize N recommendations. This study was conducted in 21 farmers' fields from 2007 to 2009, representing the maize production regions of east central and southeastern Pennsylvania, USA. Four blocks at each site included seven sidedress N rates (0-280 kg N ha(-1)) and one at-planting N rate of 280 kg N ha(-1). Canopy reflectance in the 590 nm and 880 nm wavelengths, soil samples, chlorophyll meter (SPAD) measurements and above-ground biomass were collected at the 6th-7th-leaf growth stage (V6-V7). Relative amber normalized difference vegetative index (ANDVI(relative)) and relative SPAD (SPAD(relative)) were determined based on the relative measurements from the zero sidedress treatment to the 280 kg N ha(-1) at-planting treatment. Observations from the current study were compared to relationships between economic optimum N rate (EONR) and ANDVI(relative), presidedress NO(3) test (PSNT), or SPAD(relative) that were developed from a previous study. These comparisons were based on an absolute mean difference (AMD) between observed EONR and the previously determined predicted relationships. The AMD for the relationship between EONR and ANDVI(relative) in the current study was 46 kg N ha(-1). Neither the PSNT (AMD = 66 kg N ha(-1)) nor the SPAD(relative) (AMD = 72 kg N ha(-1)) provided as good an indicator of EONR. When using all the observations from the two studies for the relationships between EONR and the various measurements, ANDVI(relative) (R(2) = 0.65) provided a better estimate of EONR than PSNT (R(2) = 0.49) or SPAD(relative) (not significant). Crop reflectance captured similar information as the PSNT and SPAD(relative), as reflected in strong relationships (R(2)>0.60) among these variables. Crop canopy reflectance using an active sensor (i.e. ANDVI(relative)) provided as good or better an indicator of EONR than PSNT or SPAD(relative), and provides an opportunity to easily adjust in-season N applications spatially.

AB Aflatoxin, a toxin produced by the fungus Aspergillus flavus Link: Fries, occurs naturally in maize (Zea mays L.). Aflatoxin is a potent human carcinogen and is also toxic to livestock, pets, and wildlife. When contaminated with aflatoxin, the value of maize grain is markedly reduced. This investigation was conducted to compare ear rot, aflatoxin accumulation, and fungal biomass in maize single crosses with varying degrees of resistance to aflatoxin accumulation and to determine the relative importance of general combining ability (GCA) and specific combining ability (SCA) in the inheritance of resistance to ear rot, aflatoxin accumulation, and fungal biomass. Eight germplasm lines with different levels of resistance to aflatoxin accumulation were used as parents of a diallel cross. The cross was evaluated for visible ear rot, aflatoxin accumulation, and A. flavus infection in the grain. A. flans infection was determined by quantitative real-time polymerase chain reaction (qRT-PCR) assays. Both GCA and SCA were significant sources of variation in the inheritance of the three traits although GCA accounted for a greater portion of the variation among single crosses. The interactions of GCA and SCA with years were highly significant for aflatoxin accumulation, but not significant for A. flavus infection. Estimates of GCA effects were highly significant for both reduced A. flavus infection and reduced aflatoxin accumulation for Mp313E, Mp715, and Mp717. Conversely, GCA effects associated with GA209 were significant for reduced levels of A. flavus infection and ear rot, but high levels of aflatoxin accumulation. Mp313E, Mp715, and Mp717 should be useful in breeding programs targeting both reduced levels of fungal infection and aflatoxin accumulation. Published by Elsevier B.V.

AB Surface porous high-performance liquid chromatography (HPLC) columns were investigated for the separation of kafirins, storage proteins of grain sorghum. Kafirins were successfully separated using C3, C8, and C18 surface porous stationary phases in less than 17 min. Separations using a monolithic C18 stationary phase were also developed and were slightly faster than those achieved on the surface porous C18 stationary phase. However, the resolution was higher on the latter column. Using an ammonium hydroxide/acetonitrile mobile phase, separations were performed on a novel, alkaline stable surface porous C18 stationary phase. The resolution at alkaline pH was not as high, however, as with the traditional acidic acetonitrile mobile phases. In comparison to fully porous stationary phases, the surface porous phases provided higher resolution with much lower separation times (17 versus 40 min). Total peak areas were correlated to total protein content of sorghum (r(2) = 0.96; n = 10), and a method to measure in vitro pepsin digestibility using reversed-phase (RP)HPLC peak areas showed good correlation to the traditional nitrogen combustion method (r(2) = 0.82; n = 20). Thus, the surface porous stationary phases could be used not only for more rapid separations but also to provide simultaneous information on total protein content and digestibility.

AB Legumes are the predominant source of isoflavones considered to be phytoestrogens that mimic the hormone 17 beta-estradiol (E2). Due to the risks associated with hormone replacement therapy, there is a growing need for alternative sources of estrogenic formulations for the treatment of menopausal symptoms. Legume phytoalexins (induced isoflavones) are produced under conditions of stress that include insect damage, wounding, or application of elicitors. The estrogenic and antiestrogenic activities of methanolic extracts obtained from red kidney bean treated with the fungus Aspergillus sojae were compared with those of untreated controls using an estrogen responsive element-based (ERE) luciferase reporter assay. A. sojae-treated red kidney bean extracts displayed both estrogenic and antiestrogenic activities. Analysis of elicitor-treated red kidney bean extracts showed that A. sojae treatments achieved maximal levels of kievitone at 1199 +/- 101 mu g/g and phaseollin at 227.8 +/- 44 mu g/g. The phytoalexins kievitone and phaseollin were isolated from A. sojae-treated red kidney bean extracts and analyzed for estrogenic activity using ER alpha and ER beta binding, ERE luciferase assays in MCF-7 and HEK 293 cells, and MCF-7 cell proliferation. Kievitone showed the highest relative binding affinity to ERa with kievitone (0.48%) > phaseollin (0.21%), and phaseollin showed the highest relative binding affinity to ER beta with phaseollin (0.53%) > kievitone (0.42%). In an ERE luciferase assay in MCF-7 cells, kievitone displayed high ER transactivation at 10 mu M; phaseollin displayed low ER transactivation. Both kievitone and phaseollin stimulated MCF-7 cell proliferation, with kievitone displaying agonist activity between 0.1 and 10 mu M. Cotransfection reporter assays performed in HEK 293 demonstrated that phaseollin selectively increased ERE transcriptional activity of ER beta and kievitone selectively increased ERE transcriptional activity of ERa. Although phaseollin displayed attenuation of ER transactivation in the ERE luciferase assay in MCF-7 cells, both phytoalexins attenuated the effects of E2 in an MCF-7 cell colonial survival assay. This work provides evidence that the red kidney bean phytoalexins kievitone and phaseollin possess both estrogenic and antiestrogenic activities.

AB Nobiletin (NOB) and tangeretin (TAN), two of the main polymethoxylated flavones (PMFs) in citrus, influence a number of key biological pathways in mammalian cells. Although the impacts of NOB and TAN on glucose homeostasis and cholesterol regulation have been investigated in human clinical trials, much information is still lacking about the metabolism and oral bioavailability of these compounds in animals. In this study, NOB and TAN were administered to rats by gavage and intraperitoneal (ip) injection, and the blood serum concentrations of these compounds and their main metabolites were monitored by high-performance liquid chromatography-electrospray ionization-mass spectrometry (HPLC-ESI-MS). In addition to the administered compounds, two metabolites of TAN and eight metabolites of NOB were detected and measured over 24 h. With identical oral doses, nearly 10-fold higher absorption of NOB occurred compared to TAN. For both compounds, maximum levels of glucuronidated metabolites occurred in the blood serum at later time points (similar to 5-8 h) compared to the earlier T-max a values for NOB and TAN. In most cases the glucuronides occurred at substantially higher concentrations than the aglycone metabolites. Low levels of NOB and TAN and their metabolites were detectable in rat blood serum even at 24 h after treatment.

AB Fish are an important source of dietary protein for humans throughout the world. However, they are recognized as one of the most common food allergens and pose a serious health problem in countries where fish consumption is high. Many marine fish allergens have been extensively studied, but relatively little is known about freshwater fish allergens. This study identified two main allergens from blunt snout bream (Megalobrama amblycephala), a freshwater fish widely consumed in China. Sera from 11 patients with convincing clinical history of blunt snout bream allergy were utilized in IgE immunoblot analysis to identify prominent allergens. Several blunt snout bream proteins revealed specific binding to serum IgE, with the 47 and 41 kDa proteins being the most immunodominant among them. Two-dimensional gel electrophoresis (2D SDS-PAGE) enabled resolution of the 47 and 41 kDa proteins into several protein spots with distinct isoelectric points. 2D SDS-PAGE along with IgE immunoblot analysis further confirmed the strong reactivity of these protein spots with the pooled sera from blunt snout bream-sensitive patients. Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) analysis of the peptides generated by trypsin digestion of the different spots corresponding to the 47 and 41 kDa proteins indicated that these spots were isoforms of enolase and muscle creatine kinase, respectively. The potential allergenicity of these proteins was further verified by an bioinformatics approach using the full-length and 80 amino acid sliding window FASTA searches, which revealed a significant amino acid sequence homology between blunt snout bream allergens and several known inhaled and crustacean allergens.

ID AMERICAN BLACK BEAR; CONSERVATION; CARNIVORES; PREDATION; PROGRAMS; LAW
AB Evidence-based decision-making is critical for implementing conservation actions, especially for human-wildlife conflicts, which have been increasing worldwide. Conservation practitioners recognize that long-term solutions should include altering human behaviors, and public education and enforcement of wildlife-related laws are two management actions frequently implemented, but with little empirical evidence evaluating their success. We used a system where human-black bear conflicts were common, to experimentally test the efficacy of education and enforcement in altering human behavior to better secure attractants (garbage) from bears. We conducted 3 experiments in Aspen CO, USA to evaluate: 1) on-site education in communal dwellings and construction sites, 2) Bear Aware educational campaign in residential neighborhoods, and 3) elevated law enforcement at two levels in the core business area of Aspen. We measured human behaviors as the response including: violation of local wildlife ordinances, garbage availability to bears, and change in use of bear-resistance refuse containers. As implemented, we found little support for education, or enforcement in the form of daily patrolling in changing human behavior, but found more support for proactive enforcement, i.e., dispensing warning notices. More broadly we demonstrated the value of gathering evidence before and after implementing conservation actions, and the dangers of measuring responses in the absence of ecological knowledge. We recommend development of more effective educational methods, application of proactive enforcement, and continued evaluation of tools by directly measuring change in human behavior. We provide empirical evidence adding to the conservation managers' toolbox, informing policy makers, and promoting solutions to human-wildlife conflicts.

It is usually assumed that this is because few invaders possess the necessary adaptations to succeed under extreme environmental conditions. Here, we show that nonnative plants reaching high elevations around the world are not highly specialized stress tolerators but species with broad climatic tolerances capable of growing across a wide elevational range. These results contrast with patterns for native species, and they can be explained by the unidirectional expansion of nonnative species from anthropogenic sources at low elevations and the progressive dropping out of species with narrow elevational amplitudes-a process that we call directional ecological filtering. Independent data confirm that climatic generalists have succeeded in colonizing the more extreme environments at higher elevations. These results suggest that invasion resistance is not conferred by extreme conditions at a particular site but determined by pathways of introduction of nonnative species. In the future, increased direct introduction of nonnative species with specialized ecophysiological adaptations to mountain environments could increase the risk of invasion. As well as providing a general explanation for gradients of nonnative species richness and the importance of traits such as phenotypic plasticity for many invasive species, the concept of directional ecological filtering is useful for understanding the initial assembly of some native floras at high elevations and latitudes.

AB Bumble bees (Bombus) are vitally important pollinators of wild plants and agricultural crops worldwide. Fragmentary observations, however, have suggested population declines in several North American species. Despite rising concern over these observations in the United States, highlighted in a recent National Academy of Sciences report, a national assessment of the geographic scope and possible causal factors of bumble bee decline is lacking. Here, we report results of a 3-y interdisciplinary study of changing distributions, population genetic structure, and levels of pathogen infection in bumble bee populations across the United States. We compare current and historical distributions of eight species, compiling a database of >73,000 museum records for comparison with data from intensive nationwide surveys of >16,000 specimens. We show that the relative abundances of four species have declined by up to 96% and that their surveyed geographic ranges have contracted by 23-87%, some within the last 20 y. We also show that declining populations have significantly higher infection levels of the microsporidian pathogen Nosema bombi and lower genetic diversity compared with co-occurring populations of the stable (nondeclining) species. Higher pathogen prevalence and reduced genetic diversity are, thus, realistic predictors of these alarming patterns of decline in North America, although cause and effect remain uncertain.

AB Forest understory grasses are of significance in the initiation, establishment and maintenance of fire, whether used as a management tool or when occurring as wildfire. The fundamental thermal properties of such grasses are critical to their behavior in fire situations and have been investigated in the current work by the application of thermogravimetric analysis (TGA). TGA was performed in nitrogen and air, over a range of heating rates, allowing for the determination of activation energies and temperatures associated with the degradation of hemicelluloses and cellulose. Of particular interest is the behavior of Imperata cylindrica (cogongrass) an invasive species in the southern United States, which has been found to result in elevated temperatures during fires in forested ecosystems. The results from TGA for this species are in accord with these observations from the field. Published by Elsevier B.V.

AB Total forest carbon (C) storage is determined by succession, disturbances, climate, and the edaphic properties of a site or region. Forest harvesting substantially affects C dynamics; these effects may be amplified if forest harvesting is intensified to provide biofuel feedstock. We tested the effects of harvest intensity on landscape C using a simulation modeling approach that included C dynamics, multiple disturbances, and successional changes in composition. We developed a new extension for the LANDIS-II forest landscape disturbance and succession model that incorporates belowground soil C dynamics derived from the CENTURY soil model. The extension was parameterized and calibrated using data from an experimental forest in northeastern Wisconsin, USA. We simulated a 9800 ha forested landscape over 400 years with wind disturbance combined with no harvesting, harvesting with residual slash left on site ('standard harvest'), and whole-tree harvesting. We also simulated landscapes without wind disturbance and without eastern hemlock (Tsuga canadensis) to examine the effects of detrital quantity and quality on C dynamics. We estimated changes in live C, detrital C, soil organic C, total C, and forest composition. Overall, the simulations without harvesting had substantially greater total C and continued to sequester C. Standard harvest simulations had more C than the whole tree harvest simulations. Under both harvest regimes, C accrual was not evident after 150 years. Without hemlock, SOC was reduced due to a decline in detritus and a shift in detrital chemistry. In conclusion, if the intensity of harvesting increases we can expect a corresponding reduction in potential C storage. Compositional changes due to historic circumstances (loss of hemlock) may also affect forest C although to a lesser degree than harvesting. The modeling approach presented enabled us to consider multiple, interacting drivers of landscape change and the subsequent changes in forest C. (C) 2010 Elsevier B.V. All rights reserved.

AB Paenibacillus larvae is a gram-positive spore-forming bacteria, causative agent of American Foulbrood (AFB), a severe disease affecting larvae of the honeybee Apis mellifera. In an attempt to detect potential virulence factors secreted by P. larvae, we identified an enolase among different secreted proteins. Although this protein is a cytosolic enzyme involved in glycolytic pathways, it has been related to virulence. The aim of the present work was to evaluate its role during the infection of honeybee larvae. Toxicity assays showed that enolase was highly toxic and immunogenic to honeybee larvae. Its production was detected inside P. larvae vegetative cells, on the surface of P. larvae spores and secreted to the external growth medium. P. larvae enolase production was also confirmed in vivo, during the infection of honeybee larvae. This protein was able to hydrolyze milk proteins as described for P. larvae, suggesting that could be involved in larval degradation, maybe through the plasmin(ogen) system. These results suggest that P. larvae enolase may have a role in virulence and could contribute to a general insight about insect-pathogen interaction mechanisms. (C) 2010 Elsevier B.V.

AB A study was undertaken to compare the virulence and serum killing resistance properties of Atlantic salmon and rainbow trout Yersinia ruckeri isolates. Five isolates, covering heatstable O-antigen O1, O2 and O5 serotypes, were tested for virulence towards fry and juveniles of both species by experimental bath challenge. The sensitivity of 15 diverse isolates to non-immune salmon and rainbow trout serum was also examined. All five isolates caused significant mortality in salmon fry. Serotype O1 isolate 06059 caused the highest mortality in salmon (74% and 70% in fry and juveniles, respectively). Isolate 06041, a typical ERM-causing serotype O1 UK rainbow trout strain, caused mortalities in both rainbow trout and salmon. None of the salmon isolates caused any mortalities in 150-250 g rainbow trout, and only serotype O2 isolate 06060 caused any significant mortality (10%) in rainbow trout fry. Disease progression and severity was affected by water temperature. Mortality in salmon caused by the isolates 06059 and 05094 was much higher at 16 degrees C (74% and 33%, respectively) than at 12 degrees C (30 and 4% respectively). Virulent rainbow trout isolates were generally resistant to sera from both species, whereas salmon isolates varied in their serum sensitivity. Convalescent serum from salmon and rainbow trout that had been infected by serotype O1 isolates mediated effective classical pathway complement killing of serotype O1 and O5 isolates that were resistant to normal sera. Overall, strains recovered from infected salmon possess a wider range of phenotypic properties (relative virulence, O serotype and possession of serum-resistance factors), compared to ERM-causing rainbow trout isolates.

AB Five Toxoplasma gondii isolates (TgPgBr1-5) were isolated from hearts and brains of pigs freshly purchased at the market of Campos dos Goytacazes, Northern Rio de Janeiro State, Brazil. Four of the five isolates were highly pathogenic in mice. Four genotypes were identified. Multi-locus PCR-DNA sequencing showed that each strain possessed a unique combination of archetypal and novel alleles not previously described in South America. The data suggest that different strains circulate in pigs destined for human consumption from those previously isolated from cats and chickens in Brazil. Further, multi-locus PCR-RFLP analyses failed to accurately genotype the Brazilian isolates due to the high presence of atypical alleles. This is the first report of multi-locus DNA sequencing of T. gondii isolates in pigs from Brazil. Published by Elsevier B.V.

AB Bovine besnoitiosis is an economically important disease in cattle caused by the protozoan parasite Besnoitia besnoiti, which occurs endemically in many countries of Africa and Asia and is spreading in Europe. Serological identification of subclinically infected cattle is important to avoid the introduction of infected animals into naive herds. Here we determine the sensitivity and specificity of the PrioCHECK (R) Besnoitia Ab, a serological test recently introduced into the European market. Analytical specificity was examined using sera from animals experimentally infected with parasites related to B. besnoiti (n = 27). Three animals experimentally infected with Neospora caninum or Toxoplasma gondii showed inconclusive reactions in the ELISA (percent positivity relative to the positive control [PP] 10% <= 20%) while all other sera reacted negative (PP < 10%). An estimate of the diagnostic specificity was obtained by analysing field sera from bovine herds without besnoitiosis but with abortion problems associated to N. caninum (n = 403). The analysis revealed a specificity of 94.3% or 96.8% depending on the applied cut-off (PP 10% or 20%, respectively). Sensitivity was assessed with sera from 110 animals of a herd in Germany where clinical bovine besnoitiosis was first diagnosed in September 2008. A positive serological reference standard was defined regarding sera from animals as reference positive, if these animals had tested positive in at least two of a panel of three other serological tests (two different B. besnoiti immunoblots and one immunofluorescence antibody test) on both of two sampling dates, November 2008 and April 2009. A diagnostic sensitivity of 91.8% or 75.5% was determined for sera collected in November 2008 and a sensitivity of 82.7% or 50% for sera collected in April 2009 (cut-off PP 10% or PP 20%, respectively). The marked drop in sensitivity from November 2008 to April 2009 was predominantly observed in reference-positive cattle without clinical signs. We conclude that PrioCHECK (R) Besnoitia Ab is a valuable diagnostic tool to detect clinically infected animals. Thus it may be used to support control measures, e.g., for the separation of infected animals from the remaining herd to avoid a further transmission of the infection within the herd.

AB American mink (Neovison vison) is a widely distributed invasive species in southern Chile. Thirty four feral minks were trapped at two distinct sites (rural and pen-urban), diet analyzed and Toxoplasma gondii exposure compared using PCR and specific antibodies. Serum samples were evaluated using a commercial latex agglutination test where a titer >= 1:32 was considered positive. Of 30 mink analyzed, 21(70%) were positive to T. gondii antibodies, with titers ranging from 1:32 to 1:2048. As expected, adult mink showed higher seroprevalence of exposure to T. gondii (18/21) than young mink (3/9) (P = 0.008). There was not statistically significant difference between sex groups (P = 0.687). Differences in seroprevalence were observed between the two sample sites with a higher proportion of positive individuals in the pen-urban area, and therefore, closer to human settlements (35.7% vs. 100%, P = 0.0001). Individuals positive to T. gondii using PCR and/or serology showed similar differences by site with higher infected individuals in pen-urban areas (58.8% vs. 100%. P = 0.007). Diet of American mink based in fecal composition analyses was mainly based on crustaceans (frequency of occurrence: crustaceans = 100%, birds and rodents < 7%), suggesting that the high observed prevalence of T. gondii infection might be more associated with its aquatic behavior (e.g. ingestion of oocysts in contaminated fresh water) than with their trophic behavior (e.g. preying over species that can have T. gondii cysts in their tissues). As an invasive species potentially subject to routine culling to maintain population sizes under control, minks could be used as a sentinel species to monitor pathogens of public and wildlife health importance, such as T. gondii, in aquatic environments.

AB Haemonchus contortus is a blood-sucking abomasal parasite of small ruminants that is responsible for major losses to producers worldwide. Resistance of this nematode to commercial anthelmintics has produced a demand for alternative control methods. Plants in the genus Artemisia have traditionally been used as anthelmintics and whole plants and plant extracts have demonstrated activity against gastrointestinal nematodes in several studies. In addition, Artemisia annua is the sole commercial source of artemisinin, the raw material used to produce drugs effective against the hemoprotozoan malaria parasites (Plasmodium species). Artemisinin derivatives have also shown efficacy against some trematodes, including Fasciola hepatica and Schistosoma species. In this study, artemisinin was tested for efficacy against H. contortus in a gerbil model of infection. Also tested in the gerbil model were an aqueous extract, an ethanolic extract and the essential oil of A. annua, and an ethanolic extract of Artemisia absinthium. In all experiments, gerbils were infected with 600 third-stage H. contortus larvae. In experiment 1, gerbils were treated orally with 400 milligrams per kilogram body weight (mg/kg BW) artemisinin once or 200 mg/kg BW artemisinin daily for 5 days (Days 4-8 post-infection). In experiment 2, gerbils were treated daily for 5 days with 600 mg/kg BW of A. annua ethanolic or aqueous extract. In Experiment 3, gerbils were treated with 1000 mg/kg BW of A. annua or A. absinthium ethanolic extract or with 300 mg/kg BW of A. annua essential oil daily for five consecutive days (Days 4-8 post-infection). No significant effects of treatment were seen with artemisinin or any of the Artemisia species extracts at the dosages studied. The non-ionic surfactant Labrosol (R) was an effective nontoxic solvent for delivery of hydrophilic plant extracts and the lipophilic essential oil used in the study. (C) 2010 Elsevier B.V.

AB All four stereoisomers of 4,8-dimethyldecanal (1) were synthesized from the enantiomers of 2-methyl-1-butanol and citronellal. Enantioselective GC analysis enabled separation of (4R,8R)-1 and (4R,8S)-1 from a mixture of (45,8R)-1 and (4S,8S)-1, when octakis-(2,3-di-O-methoxymethyl-6-O-tert-butyldimethylsilyl)-gamma-cyclodextrin was employed as a chiral stationary phase. Complete separation of the four stereoisomers of 1 on reversed-phase HPLC at -54 degrees C was achieved after oxidation of 1 to the corresponding carboxylic acid 12 followed by its derivatization with (1R,2R)-2-(2,3-anthracenedicarboximido) cyclohexanol, and the natural 1 was found to be a mixture of all the four stereoisomers.

AB Background: The bacterial pathogen Edwardsiella ictaluri is a primary cause of mortality in channel catfish raised commercially in aquaculture farms. Additional treatment and diagnostic regimes are needed for this enteric pathogen, motivating the discovery and characterization of bacteriophages specific to E. ictaluri.
Results: The genomes of three Edwardsiella ictaluri- specific bacteriophages isolated from geographically distant aquaculture ponds, at different times, were sequenced and analyzed. The genomes for phages eiAU, eiDWF, and eiMSLS are 42.80 kbp, 42.12 kbp, and 42.69 kbp, respectively, and are greater than 95% identical to each other at the nucleotide level. Nucleotide differences were mostly observed in non-coding regions and in structural proteins, with significant variability in the sequences of putative tail fiber proteins. The genome organization of these phages exhibit a pattern shared by other Siphoviridae.
Conclusions: These E. ictaluri-specific phage genomes reveal considerable conservation of genomic architecture and sequence identity, even with considerable temporal and spatial divergence in their isolation. Their genomic homogeneity is similarly observed among E. ictaluri bacterial isolates. The genomic analysis of these phages supports the conclusion that these are virulent phages, lacking the capacity for lysogeny or expression of virulence genes. This study contributes to our knowledge of phage genomic diversity and facilitates studies on the diagnostic and therapeutic applications of these phages.

AB Background: Ticks are regarded as the most relevant vectors of disease-causing pathogens in domestic and wild animals. The cattle tick, Rhipicephalus (Boophilus) microplus, hinders livestock production in tropical and subtropical parts of the world where it is endemic. Tick microbiomes remain largely unexplored. The objective of this study was to explore the R. microplus microbiome by applying the bacterial 16S tag-encoded FLX-titanium amplicon pyrosequencing (bTEFAP) technique to characterize its bacterial diversity. Pyrosequencing was performed on adult males and females, eggs, and gut and ovary tissues from adult females derived from samples of R. microplus collected during outbreaks in southern Texas.
Results: Raw data from bTEFAP were screened and trimmed based upon quality scores and binned into individual sample collections. Bacteria identified to the species level include Staphylococcus aureus, Staphylococcus chromogenes, Streptococcus dysgalactiae, Staphylococcus sciuri, Serratia marcescens, Corynebacterium glutamicum, and Finegoldia magna. One hundred twenty-one bacterial genera were detected in all the life stages and tissues sampled. The total number of genera identified by tick sample comprised: 53 in adult males, 61 in adult females, 11 in gut tissue, 7 in ovarian tissue, and 54 in the eggs. Notable genera detected in the cattle tick include Wolbachia, Coxiella, and Borrelia. The molecular approach applied in this study allowed us to assess the relative abundance of the microbiota associated with R. microplus.
Conclusions: This report represents the first survey of the bacteriome in the cattle tick using non-culture based molecular approaches. Comparisons of our results with previous bacterial surveys provide an indication of geographic variation in the assemblages of bacteria associated with R. microplus. Additional reports on the identification of new bacterial species maintained in nature by R. microplus that may be pathogenic to its vertebrate hosts are expected as our understanding of its microbiota expands. Increased awareness of the role R. microplus can play in the transmission of pathogenic bacteria will enhance our ability to mitigate its economic impact on animal agriculture globally. This recognition should be included as part of analyses to assess the risk for re-invasion of areas like the United States of America where R. microplus was eradicated.

AB Wild birds in the Orders Anseriformes and Charadriiformes are the natural reservoirs for avian influenza (AI) viruses. Although they are often infected with multiple AI viruses, the significance and extent of acquired immunity in these populations is not understood. Pre-existing immunity to AI virus has been shown to modulate the outcome of a highly pathogenic avian influenza (HPAI) virus infection in multiple domestic avian species, but few studies have addressed this effect in wild birds. In this study, the effect of pre-exposure to homosubtypic (homologous hemagglutinin) and heterosubtypic (heterologous hemagglutinin) low pathogenic avian influenza (LPAI) viruses on the outcome of a H5N1 HPAI virus infection in wood ducks (Aix sponsa) was evaluated. Pre- exposure of wood ducks to different LPAI viruses did not prevent infection with H5N1 HPAI virus, but did increase survival associated with H5N1 HPAI virus infection. The magnitude of this effect on the outcome of the H5N1 HPAI virus infection varied between different LPAI viruses, and was associated both with efficiency of LPAI viral replication in wood ducks and the development of a detectable humoral immune response. These observations suggest that in naturally occurring outbreaks of H5N1 HPAI, birds with pre-existing immunity to homologous hemagglutinin or neuraminidase subtypes of AI virus may either survive H5N1 HPAI virus infection or live longer than naive birds and, consequently, could pose a greater risk for contributing to viral transmission and dissemination. The mechanisms responsible for this protection and/or the duration of this immunity remain unknown. The results of this study are important for surveillance efforts and help clarify epidemiological data from outbreaks of H5N1 HPAI virus in wild bird populations.

AB Pretreatment of lignocellulosic materials may result in the release of inhibitors and deactivators of cellulose enzyme hydrolysis. We report the identification of phenols with major inhibition and/or deactivation effect on enzymes used for conversion of cellulose to ethanol. The inhibition effects were measured by combining the inhibitors (phenols) with enzyme and substrate immediately at the beginning of the assay. The deactivation effects were determined by pre-incubating phenols with cellulases or beta-glucosidases for specified periods of time, prior to the respective enzyme assays. Tannic, gallic, hydroxy-cinnamic, and 4-hydroxybenzoic acids, together with vanillin caused 20-80% deactivation of cellulases and/or beta-glucosidases after 24 h of pre-incubation while enzymes pre-incubated in buffer alone retained all of their activity. The strength of the inhibition or deactivation effect depended on the type of enzyme, the microorganism from which the enzyme was derived, and the type of phenolic compounds present. beta-Glucosidase from Aspergillus niger was the most resistant to inhibition and deactivation, requiring about 5 and 10-fold higher concentrations, respectively, for the same levels of inhibition or deactivation as observed for enzymes from Trichoderma reesei. Of the phenol molecules tested, tannic acid was the single, most damaging aromatic compound that caused both deactivation and reversible loss (inhibition) of all of enzyme activities tested.

AB This study investigated the effect of fiber hornification during drying on lignocellulosic substrate enzymatic saccharification. Two chemically pretreated wood substrates and one commercial bleached kraft hardwood pulp were used. Heat drying at 105 and 150 degrees C and air drying at 50% RH and 23.8 degrees C for different durations were applied to produce substrate with various degrees of hornification. It was found that substrate enzymatic digestibilities (SEDs) of hornified substrates made from the same never-dried sample correlate very well to an easily measurable parameter, water retention value (WRV), and can be fitted by a Boltzmann function. The hornification-produced SED reduction at a given degree of hornification as the percentage of the total SED reduction when the substrate is completely hornified depends on two parameters. The first is WRV, which is primarily a function of the effective enzyme molecule size, and Delta, which is related to the substrate pore size distribution shape. The low values of SED(CH), SED of a completely hornified substrate, obtained from curve fittings for the three sets of samples studied, suggest that enzyme accessibility to cellulose is mainly through the pores in the cell wall rather than substrate external surface. The SEDs of hornified substrates were found to correlate to Simons' staining measurements well. A new parameter was proposed to better correlate enzyme accessibility to cellulose using the two-color Simons' staining technique. Published by Elsevier Inc.

AB The efficacy of carvacrol (CAR), trans-cinnamaldehyde (TC), eugenol (EUG) and beta-resorcylic acid (BR) as a wash treatment for reducing Salmonella spp. on tomatoes was investigated. Plum tomatoes inoculated with a six-serotype mixture of Salmonella (10(8) CFU) were subjected to washing in sterile deionized water (control) or deionized water containing chlorine (100 ppm), CAR (0.25 and 0.75%), TC (0.5 and 0.75%), EUG (0.25 and 0.75%), or BR (0.75 and 1.0%) for 15 sec, 1 min, and 3 min. The plant molecules were more effective (P<0.05) in reducing Salmonella on tomatoes compared to washing in water and chlorine. Both concentrations of CAR and TC, and 0.75% EUG decreased Salmonella counts on tomatoes by similar to 6.0 log CFU/ml at 1 min. Both concentrations of BR decreased the pathogen on tomatoes to undetectable levels at 3 min of exposure. Washing of tomatoes in deionized water and chlorine for 3 min reduced Salmonella by ca. 2.0 and 4.0 log CFU/ml, respectively. No Salmonella was detected in the wash water containing the plant molecules or chlorine, whereas a substantial population of the pathogen survived in the control wash water. Moreover, none of the dipping treatments had any effect on the red color of tomatoes (P>0.05). Results indicate that CAR, TC, EUG and BR could effectively be used to kill Salmonella on tomatoes, but additional studies on sensory and quality characteristics of tomatoes treated with plant molecules are warranted.

AB The Autographa californica multiple nucleopolyhedrovirus (AcMNPV) occlusion-derived virus (ODV) envelope protein ODV-E56 is essential for oral infection of larvae of Heliothis virescens. Bioassays with recombinant clones of AcMNPV lacking a functional odv-e56 gene showed that ODV-E56 was required for infectivity of both polyhedra and to a lesser extent, purified ODV. However, binding and fusion assays showed that ODV lacking ODV-E56 bound and fused to midgut cells at levels similar to ODV of wild-type virus. Fluorescence microscopy of midguts from larvae inoculated with ODV-E56-positive and -negative viruses that express GFP indicated that ODV-E56 was required for infection of the midgut epithelium. Purified ODV-E56 bound to several proteins in midgut-derived brush border membrane vesicles, but failed to rescue infectivity of ODV-E56-negative viruses in trans. These results indicate that ODV-E56 is a per os infectivity factor (pif-5) required for primary midgut infection at a point before or after virion binding and fusion. (C) 2010 Elsevier Inc.

TI Nitrous oxide emission from denitrification in stream and river networks

AB Nitrous oxide (N2O) is a potent greenhouse gas that contributes to climate change and stratospheric ozone destruction. Anthropogenic nitrogen (N) loading to river networks is a potentially important source of N2O via microbial denitrification that converts N to N2O and dinitrogen (N-2). The fraction of denitrified N that escapes as N2O rather than N-2 (i.e., the N2O yield) is an important determinant of how much N2O is produced by river networks, but little is known about the N2O yield in flowing waters. Here, we present the results of whole-stream N-15-tracer additions conducted in 72 headwater streams draining multiple land-use types across the United States. We found that stream denitrification produces N2O at rates that increase with stream water nitrate (NO3-) concentrations, but that <1% of denitrified N is converted to N2O. Unlike some previous studies, we found no relationship between the N2O yield and stream water NO3-. We suggest that increased stream NO3- loading stimulates denitrification and concomitant N2O production, but does not increase the N2O yield. In our study, most streams were sources of N2O to the atmosphere and the highest emission rates were observed in streams draining urban basins. Using a global river network model, we estimate that microbial N transformations (e. g., denitrification and nitrification) convert at least 0.68 Tg.y(-1) of anthropogenic N inputs to N2O in river networks, equivalent to 10% of the global anthropogenic N2O emission rate. This estimate of stream and river N2O emissions is three times greater than estimated by the Intergovernmental Panel on Climate Change.

AB The Rusty Blackbird (Euphagus carolinus), a formerly common breeding species of boreal wetlands, has exhibited the most marked decline of any North American landbird. North American Breeding Bird Survey (BBS) trends in abundance are estimated to be -12.5%/yr over the last 40 years, which is tantamount to a >95% cumulative decline. Trends in abundance calculated from Christmas Bird Counts (CBC) for a similar period indicate a range-wide decline of -5.6%/yr. Qualitative analyses of ornithological accounts suggest the species has been declining for over a century. Several studies document range retraction in the southern boreal forest, whereas limited data suggest that abundance may be more stable in more northerly areas. The major hypotheses for the decline include degradation of boreal habitats from logging and agricultural development, mercury contamination, and wetland desiccation resulting from global warming. Other likely reasons for decline include loss or degradation of wooded wetlands of the southeastern U. S and mortality associated with abatement efforts targeting nuisance blackbirds. In addition, the patchy breeding distribution of this species may inhibit population consolidation, causing local populations to crash when reduced to low levels. Progress in understanding the causes and mechanisms for observed declines has remained limited until recently. Here we present initial attempts to understand the habitat requirements of Rusty Blackbirds and offer specific predictions associated with each of the hypotheses for decline as a way of guiding future research.

AB How hunting mortality affects population size is an important but understudied problem in the applied ecology of grouse and other upland gamebirds. At issue is whether mortality from recreational hunting is additive and therefore depresses population size, or is compensatory and does not. Empirical analyses of this issue may be inconclusive if harvest levels increase with population size or if statistical analysis fails to control for serial dependence in estimates of population size. We examined the effect of hunting on population size in Greater Sage-Grouse (Centrocercus urophasianus) using a lek count time series from an intermittently hunted and relatively isolated population in eastern California. Over a 39-year study period (1960-1998), annual variation in harvest recorded in the field was uncorrelated with the previous spring's lek count. After controlling for a positive correlation between lek counts in successive years, numbers of males on leks in spring decreased significantly as harvest during the previous autumn increased. This pattern is expected if hunting mortality is additive and lowers population size. In light of this and similar results from an independent study in Idaho, we suggest that additive, rather than compensatory, hunting mortality should become the default assumption for wildlife managers when setting hunting regulations for Greater Sage-Grouse.

AB The establishment of broadly applicable insect transgenesis systems will enable the analyses of gene function in diverse insect species. This will greatly increase our understanding of diverse aspects of biology so far not functionally addressable. Moreover, insect transgenesis will provide novel strategies for insect pest management and the means to impair transmission of pathogens by human disease vectors. Especially the Sterile Insect Technique (SIT) might be improved by the use of transgenic approaches. The SIT represents an effective and ecologically safe method for area-wide pest control that reduces the pest population by mass release of sterilized organisms, leading to infertile matings and in consequence to a decline of the pest population. Although the SIT is already successfully applied for some species, each of its steps mass-rearing, sex-separation for male-only releases, sterilization, and marking for monitoring can be improved biotechnologically to optimize the efficiency and to reduce the costs of ongoing programs or to transfer this effective technique to a wider range of species. However, this powerful transgenic technology must be applied with great care to avoid harm to our environment.

AB Background: Intake of industrially produced trans fatty acids (TFAs) is, according to observational studies, associated with an increased risk of cardiovascular disease, but the causal mechanisms have not been fully elucidated. Besides inducing dyslipidemia, TFA intake is suspected to promote abdominal and liver fat deposition.
Objective: We examined the effect of a high intake of TFA as part of an isocaloric diet on whole-body, abdominal and hepatic fat deposition, and blood lipids in postmenopausal women.
Methods: In a 16-week double-blind parallel intervention study, 52 healthy overweight postmenopausal women were randomized to receive either partially hydrogenated soybean oil providing 15.7 g day(-1) of TFA or a control oil with mainly oleic and palmitic acid. Before and after the intervention, body composition was assessed by dual-energy X-ray absorptiometry, abdominal fat by magnetic resonance (MR) imaging, and liver fat by H-1 MR spectroscopy.
Results: Compared with the control fat, TFA intake decreased plasma high-density lipoprotein (HDL)-cholesterol by 10%, increased low-density lipoprotein (LDL)-cholesterol by 18% and resulted in an increased LDL/HDL-cholesterol ratio (baseline adjusted mean (95% CI) difference between diet groups 0.41 (0.22; 0.60); P<0.001). TFA tended to increase the body fat (0.46 (-0.20; 1.17) kg; P = 0.16) and waist circumference (1.1 (-0.1; 2.4) cm; P = 0.08) more than the control fat, whereas neither abdominal nor liver fat deposition was affected by TFA.
Conclusion: The adverse effect of dietary TFA on cardiovascular disease risk involves induction of dyslipidemia, and perhaps body fat, whereas weight gain-independent accumulation of ectopic fat could not be identified as a contributory factor during short-term intake.

AB Global climate change, driven by the buildup of greenhouse gas (GHG) emissions in the atmosphere, is challenging the dairy industries in the United States and throughout the world to develop sustainable initiatives to reduce their environmental impact. The U. S. dairy industry has committed to lowering the GHG emissions, primarily CH4, N2O, and CO2, in each sector of the fluid milk supply chain which extends from the farm, to the processing plant, and to distribution of the packaged product, where it is refrigerated by the retailer and then the consumer. This chapter provides an overview of the life cycle analysis (LCA) technique and its use in identifying the GHG emissions in each sector of the fluid milk supply chain, from cradle to grave, and the best practices and research that is currently being conducted to reduce or mitigate GHG emissions in each sector. We also discuss the use of on-farm and off-farm process simulation as tools for evaluating on-farm mitigation techniques, off-farm alternative processing scenarios, and use of alternative energy management practices.

AB The primary proteins in milk, casein and the whey proteins alpha-lactalbumin and beta-lactoglobulin, have a number of health benefits and desirable functional properties. In a twin-screw extruder, mechanical shear forces, heat, and pressure cause considerable changes in the molecular structures of the dairy proteins, a process known as texturization. These changes further impart unique functional properties to dairy proteins, resulting in new protein-based food ingredients. The new functional behavior depends on the extent of texturization and the degree of structural change imparted and is controlled by adjusting parameters such as extrusion temperature and moisture level. Such texturized proteins can be used to produce puffed high-protein snacks. Softer gels and expanded structures can be made using supercritical fluid extrusion and cold extrusion, techniques that avoid elevated temperatures, minimizing possible damage to the nutritive components and functionality of the texturized dairy proteins. The uses of the texturized dairy ingredient in food products with improved functionality and enhanced nutritive profiles are presented.

TI The Effect of GM Labeling Regime on Market Outcomes
SO GENETICALLY MODIFIED FOOD AND GLOBAL WELFARE

DT Article; Book Chapter
DE GM labeling; mandatory labeling; GM markets; non-GM markets
ID GENETICALLY-MODIFIED FOOD; EUROPE
AB Purpose - This chapter investigates the role that mandatory genetically modified (GM) labeling versus voluntary labeling has played in the split between those countries with small GM markets and those with large GM markets.
Methodology/approach - Data on product introductions and other market evidence are used to examine market outcomes and identify the likely drivers of GM market bifurcation.
Findings - Labeling has negligible effects on consumer choice or on GM differentiation costs and therefore does not explain the split in GM market outcomes. Other factors have driven market outcomes: namely, consumer confidence in government and the safety of the food supply, competition among manufacturers and retailers, market momentum, and most importantly, the affordability of a non-GM strategy. Ultimately, a non-GM market strategy is feasible only if consumers are willing to cover the additional costs associated with non-GM production and marketing. The two elements composing the cost/price wedge between GM and non-GM products - the cost-reducing benefits of the GM technology and the costs of differentiating non-GM products - therefore play an important role in market outcomes. In the mid-1990s, when producers, manufacturers, and retailers were determining their strategies, neither element was very large. As a result, both GM and non-GM marketing strategies were economically feasible.
Practical implication - Regardless of the labeling regime, changes in the cost/price wedge between GM and non-GM products could change the mix of GM and non-GM products on the market.
Originality/value of paper - This analysis extends the literature by focusing on the impact of labeling regime on both consumer behavior and the cost/price wedge between GM and non-GM products.

AB Microwave treatment is a newly developed technique to expel resin from pine wood by generating high internal steam pressure. To understand the mechanism of deresination process during the treatment, a mathematical model was developed and was used to predict its critical conditions. The model indicated that the critical pressure inside Masson pine wood was 1.17x10(5) Pa and its corresponding critical temperature was 104 C-degrees in order to expel the resin mixture from the interior to the surfaces. The experiment results showed that during microwave deresination large quantities of the resin overflowed to the wood surfaces when the temperature of the pine wood was controlled in the range 104-112 degrees C. The result observed during the microwave treatment matched well with the critical temperature predicted from the simple mathematical model. The validated model could provide some understanding and improvement of microwave deresination process.

AB Production of the harmful carcinogenic aflatoxins by Aspergillus parasiticus and Aspergillus flavus has been postulated to be a mechanism to relieve oxidative stress. The msnA gene of A. parasiticus and A. flavus is the ortholog of Saccharomyces cerevisiae MSN2 that is associated with multi-stress response. Compared to wild type strains, the msnA deletion (Delta msnA) strains of A. parasiticus and A. flavus exhibited retarded colony growth with increased conidiation. The Delta msnA strains also produced slightly higher amounts of aflatoxins and elevated amounts of kojic acid on mixed cereal medium. Microarray assays showed that expression of genes encoding oxidative stress defense enzymes, i.e., superoxide dismutase, catalase, and cytochrome c peroxidase in A. parasiticus Delta msnA, and the catalase A gene in A. flavus Delta msnA, was up-regulated. Both A. parasiticus and A. flavus Delta msnA strains produced higher levels of reactive oxygen species (ROS), and ROS production of A. flavus msnA addback strains was decreased to levels comparable to that of the wild type A. flavus. The msnA gene appears to be required for the maintenance of the normal oxidative state. The impairment of msnA resulted in the aforementioned changes, which might be used to combat the increased oxidative stress in the cells.

TI Relationship between skin color and some fruit quality characteristics
of 'Hass' avocado
SO JOURNAL OF AGRICULTURE OF THE UNIVERSITY OF PUERTO RICO
LA English
DT Article
DE Skin blackening; firmness; dry matter; weight; maturity index
ID OIL CONTENT; DRY-MATTER
AB Mexico is the main 'Hass' avocado exporter in the world. More than 300,000 t are exported every year. The United States of America, Japan, the European Union, and Canada are the main importer countries. Recently, 'Hass' avocado shipments to Canada containing fruit with skin blackening have been rejected since this characteristic is associated with low pulp firmness and short shelf life. The objective of this study was to determine the relationship between skin color of 'Hass' avocado fruit with quality characteristics. Fruit varying in black skin color (from 0 to 100%, categories 1 to 5) were collected from two different packinghouses in Michoacan, Mexico. Treatments were arranged in a split-plot design with five replications. Significant differences were detected between packinghouses for weight, length, skin color ('a', 'b', chroma and hue) and pulp firmness but not for width, dry matter content or the Avocado Maturity Index (AMI). As color skin category increased towards more blackened fruit, AMI value increased, firmness decreased but dry matter content did not change. These results provide evidence that fruit skin blackening is not associated with lower fruit quality, but it did lower pulp firmness at fruit packing.

ID GROWTH; TECHNOLOGY; INDEX
AB Agricultural productivity in sub-Saharan Africa remains low and is falling further behind the rest of the world. Nevertheless, agricultural output growth for the region accelerated in the 1990s and if sustained could spur economic development and poverty reduction. This chapter combines production function and index number approaches while incorporating natural resource quality variables to explore patterns of agricultural productivity growth in sub-Saharan Africa between 1961 and 2008. The results indicate that most of the recent rise in agricultural productivity has been due to resource expansion that can be explained in part by improved macroeconomic and political environments. The rise in global commodity prices since 2006 has also improved agriculture's terms of trade. In addition, there is evidence that total factor productivity growth improved in some countries. This chapter explores possible reasons why some African countries have apparently been able to accelerate agricultural productivity growth and whether this can be sustained.

TI An Overview of the Forest Products Sector Downturn in the United States
SO FOREST PRODUCTS JOURNAL
LA English
DT Article
ID CONSUMPTION; US
AB In recent years, the forest products industry of the U.S. experienced a downturn in output to levels not seen in decades and employment losses in the hundreds of thousands -- for instance, a number far greater than witnessed in the Nation's automotive industry. The extent of the forest industry downturn varies by sector, impacted by structural changes in the overall economy coupled with substantial impacts from the Great Recession. Globalization of manufacturing and expanded use of electronic communication media contributed to a decline in U.S. pulp, paper, and paperboard output since the late 1990s, while the collapse of housing construction since 2006 and off-shoring of furniture production contributed to declines in U.S. wood product output. The paper points to structural changes that may be difficult to reverse, but also points to some potential prospects for growth in the future such as increased secondary product manufacturing and wood energy. This paper serves as an introduction to the extent of the downturn with a particular focus on trends in forest sector economic production and employment across the U.S. Because the nation's forest industry varies by region due to differences in forest resources and forest industries, additional regional examinations of this downturn (same issue) will highlight variations in the regional industrial response to the "Great Recession."

TI An Assessment of the Downturn in the Forest Products Sector in the
Northern Region of the United States
SO FOREST PRODUCTS JOURNAL
LA English
DT Article
AB The forest industry within the northern region of the U.S. has declined notably in employment, mill numbers, wood consumption, and forest harvests since 2000...a downturn exacerbated by the recession of 2007 to 2009. Longer term industrial decline (since 2000) has been evidenced by reductions in secondary products (e.g., furniture) and print paper manufacturing which cab be attributed, respectively, to the lack of global competitiveness due to high U.S. wages and ascent of electronic media. In contrast, shorter term (since 2008), yet sharper declines occured in industries such as composite panel production that serve the housing industry. Despite a decade of decline, there are future opportunities for this region's forest industry. The region's forests are predominantly sawtimber (e.g., select hardwoods). Compled with this natural resource is a present, but underutilized industry with excess capacity and a skilled work force. As evidenced by recent trends in positive trade balances, the decline of the northern region's forest industry may be mitigated with a focus on new markets (e.g., wood energy) and balancing increased export of unfinished products (e.g., logs) with increased use of the region's skilled secondary product workforce (e.g., increasing international competiveness of U.S. producition).

TI Recession Effects on the Forests and Forest Products Industries of the
South
SO FOREST PRODUCTS JOURNAL
LA English
DT Article
AB The economic recession affected southern forests and related industries substantially, particularly those sectors most closely related to home construction. Between 2005 and 2009, for example, the three primary forestry sectors wood manufacturing, paper manufacturing, and forestry and logging - lost more than 110,000 jobs in the southern United States. This article assesses the effects of the recession on the southern U.S. by reviewing existing data related to economic and resource impacts, including employment, timber product output, production facilities, state economies, exports, and forest area and management activities. While all sectors were affected, wood products and furniture manufacturing experienced the greatest change. As a result of the downturn, the South's forest sector's direct contribution to the regional economies decreased by 24 percent between 2004 and 2009. Some developments such as rebounding paper consumption, expanding export markets, and bioenergy, however, offer potential growth opportunities for the future.

TI Impact of the Great Recession and Housing Collapse on the Forest
Products Industry in the Western United States
SO FOREST PRODUCTS JOURNAL
LA English
DT Article
AB The first decade of the Twenty-first Century proved tumultuous for the West's forest products industry. A strong economy, low interest rates, easy access to credit, and real estate speculation fostered more than two million U.S. housing starts in 2005 and record lumber consumption from 2003 to 2005. With the decline in U.S. housing beginning in 2006, the 2008 global financial crisis, an over 50-year record low 554,000 housing starts in 2009, wood product prices and production fell dramatically. In 2009 and 2010, virtually every major western mill suffered curtailments and 30 large mills closed permanently. Sales value of wood and paper products in the West dropped from $49 billion in 2005 to $34 billion in 2009. Employment declined by 71,000 workers and lumber production fell by almost 50 percent from 2005 to 2009. Capacity utilization at sawmills and other timber-using facilities in the West fell from over 80 percent in 2005 to just over 50 percent in 2009 and 2010. With the exception of exports and some paper markets, U.S. wood products markets have improved little since the recession officially ended in 2009. Modest improvements are expected in domestic markets in the short term but substantial improvements are unlikely until 2014 or later, as U.S. home building recovers and global demand increases. Much of the West retains the bulk of its pre-recession (2006) capacity and mills could respond quickly to increased demand spurred by economic recovery.

TI Predicting Internal White Oak (Quercus alba) Log Defect Features Using
Surface Defect Indicator Measurements
SO FOREST PRODUCTS JOURNAL
LA English
DT Article
AB As hardwood trees grow and develop, surface defects such as limb stubs and wounds are overgrown and encapsulated into the tree. Evidence of these defects can remain on the tree's surface for decades and in many instances for the life of the tree. The location and severity of internal defects dictate the quality and value of products that can be obtained from logs. Thus, log surface defect indicators such as log diameter at defect and surface indicator width, length, and rise provide a viable means of estimating the location and severity of internal defects. Evaluation of white oak (Quercus alba) log defects revealed that good correlations exist between external indicators and internal features for most severe defect types. Weaker correlations were observed with less severe defect types, such as bark distortions and adventitious knots.

Thinning in Mixed-Conifer Forest
SO FOREST PRODUCTS JOURNAL

DT Article
ID WESTERN UNITED-STATES; FIRE; SYSTEMS; ECONOMICS; POLICY; ENERGY; STAND;
TREES; USA
AB Removing submerchantable size trees and forest residues as well as sawlogs is preferred in fuel reduction thinning because it improves treatment effectiveness and avoids slash burning. Fuel reduction thinning was investigated to describe integrated harvesting machine processes and productivity and to characterize stump-to-truck costs for sawlogs and biomass for energy production. This system was studied in mixed-conifer forest on land owned by the US Forest Service in northern California and southern Oregon. Detailed time-study methods were paired with standard machine rate calculation methods to evaluate productivity and costs for the system. Sensitivity analysis and a standardized comparison were performed to evaluate costs and productivity under varying operation parameters. Treatment costs (stump-to-truck; without mobilization, overhead, or profit) were US$0.42/ft(3) for sawlogs and US$52.41 per bone dry ton (BDT) for biomass. Standardized unit production costs for sawlog skidding varied little, but the smaller skidder was clearly preferable for biomass tree skidding when external skidding distances exceeded 200 feet. The grinder had the highest hourly cost of any machine in the system and its unit production cost (USS/BDT) was sensitive to changes in utilization rate. Evaluations on system balance showed that improved utilization of the grinder could be accomplished as the grinder and loader often waited for a chip van. Integrated harvesting was a cost-effective way of implementing fuel reduction thinning method because of the potential for sawlog revenues to offset some of the biomass extraction cost.

AB Tightly controlled gene expression is a hallmark of multicellular development and is accomplished by transcription factors (TFs) and microRNAs (miRNAs). Although many studies have focused on identifying downstream targets of these molecules, less is known about the factors that regulate their differential expression. We used data from high spatial resolution gene expression experiments and yeast one-hybrid (Y1H) and two-hybrid (Y2H) assays to delineate a subset of interactions occurring within a gene regulatory network (GRN) that determines tissue-specific TF and miRNA expression in plants. We find that upstream TFs are expressed in more diverse cell types than their targets and that promoters that are bound by a relatively large number of TFs correspond to key developmental regulators. The regulatory consequence of many TFs for their target was experimentally determined using genetic analysis. Remarkably, molecular phenotypes were identified for 65% of the TFs, but morphological phenotypes were associated with only 16%. This indicates that the GRN is robust, and that gene expression changes may be canalized or buffered. Molecular Systems Biology 7: 459; published online 18 January 2011; doi:10.1038/msb.2010.114

AB Calibrachoa (Calibrachoa x hybrida) is a popular annual ornamental that was introduced in the late 1990s by the greenhouse ornamental industry. Little is published about its interaction with pathogens commonly associated with greenhouse production. We report here for the first time the response of Calibrachoa to infection by pathogens that may be introduced in greenhouse production cycles through the use of infested soil, contaminated tools, infected cuttings, and contaminated irrigation water. Rooted cuttings of 'Colorburst Violet' were artificially inoculated with isolates from Phytophthora, Pythium, Verticillium and Botrytis. Symptoms expressed in response to infection included interveinal chlorosis of young leaves, wilting and necrotic root tips with fewer or no secondary or tertiary roots. Non-challenged plants had healthy root systems with an abundance of primary, secondary, and tertiary roots. We observed a 12 to >80% decrease in root fresh weight in symptomatic plants compared to plants that showed no disease symptoms. All isolates from infected plants were recovered and identities confirmed. Greenhouse managers and clinicians should be aware that Calibrachoa is susceptible to several important plant pathogens and should scout regularly for them in order to exclude them as much as possible from their production systems.

AB Rapid identification of bacterial microorganisms is particularly relevant to efforts to monitor the safety and security of domestically grown and imported foods. Mass spectrometry (MS) is increasingly utilized to identify and characterize bacterial microorganisms and in particular food-borne pathogens. Matrix-assisted laser desorption/ionization (MALDI) time-of-flight time-of-flight tandem mass spectrometry (TOF-TOF-MS/MS) has recently been shown to fragment small and modest-sized singly-charged protein ions (without prior protein digestion) to generate sequence-specific fragment ions. These sequence-specific fragment ions can be used for identification of the protein and, if the protein sequence is sufficiently unique, the source microorganism. Our group has developed web-based software for rapid top-down identification of protein biomarkers of bacterial microorganisms from sequence-specific fragment ions analyzed by MALDI-TOF-TOF-MS/MS. The software rapidly compares the mass-to-charge (m/z) of MS/MS fragment ions to the m/z of in silico fragment ions derived from hundreds of bacterial protein sequences that have the same molecular weight as the protein biomarker ion. We have identified several protein biomarkers from pathogenic and non-pathogenic E. coli using this top-down proteomic identification approach.

AB Functional medical textiles are undergoing a revolution in structural design. Medical textiles as non-implantables, implantables and extracorporeals are playing central roles in healthcare improvements enhancing and prolonging the quality of life. Developments in the design of materials that function at the biological-material interface address material biocompatibility and bioactive function. A deeper understanding of the physiological, biochemical and biophysical milieus of biomaterials is being achieved in critical areas like wound healing, implant biocompatibility, dialysis and pressure ulcer prevention, which coupled with advances in nanotechnology holds great promise for tissue engineering and areas of biomaterial design for wound healing and prevention.

AB Microarrays have emerged as an important tool in identifying changes in gene expression under different conditions, including plant responses to pathogen infection. A logical extension of the technology is the detection of the pathogen itself, and a number of laboratories have developed either macroarrays or microarrays capable of detection and differentiation of the viruses known to infect a specific crop. Microarrays, broad spectrum PCR, Real-time PCR, and other methods of detecting multiple viruses are discussed.

ID MOSAIC POTEXVIRUS; IDENTIFICATION
AB Several species of Phlox are commonly cultivated as perennial bedding plants, and hybrid varieties of annual phlox (Phlox drummondii) have recently entered the market as vegetatively propagated pot plants. Virus-like symptoms are commonly observed in plants offered for sale. We have detected several viruses in different species of phlox, typically in mixed infections of up to five distinct viruses, using a combination of electron microscopy, host range, and broad-spectrum or virus-specific serological or polymerase chain reaction (PCR) assays. The potexvirus Alternanthera mosaic virus (AltMV) was detected in plants of creeping phlox (P. stolonifera), sweet William phlox (P. divaricata), and downy phlox (P. pilosa). One novel carlavirus, which we have named Phlox virus S (PhlVS), was isolated from P. stolonifera; another previously undescribed carlavirus, Phlox virus B (PhlVB), was detected only in P. divaricata; a third carlavirus, Phlox virus M (PhlVM), was detected in hybrid annual phlox. Two distinct potyviruses were detected, Spiranthes mosaic virus 3 (SpiMV-3), and a previously undescribed potyvirus; both were found together in P. stolonifera 'Blue Ridge' and 'Bruce's White', and in P. glaberrima 'Anita Kistler'. SpiMV-3 was also detected in P. divaricata, and potyvirus isolates of as yet-undetermined sequence were also detected in P. divaricata, P. pilosa, and P. subulata. Tobamovirus isolates were found in P. stolonifera, P. divaricata and P. subulata, Cucumber mosaic virus (CMV) in P. subulata, and Tobacco ringspot virus (TRSV) in P. stolonifera and P. subulata. Angelonia flower break virus (AnFBV, carmovirus) has been detected in hybrid annual phlox (P. drummondii) in combination with PhlVM. However, it is difficult to determine which viruses are most important, as there is little difference in symptom severity between P. stolonifera plants carrying a single virus (AltMV) and plants infected with up to five viruses (AltMV, PhlVS, TRSV, SpiMV3, and a novel potyvirus).
We have determined the complete sequences of PhlVS and PhlVB, and the 3'-terminal region of PhlVM. These three viruses infect different species of phlox, are clearly distinct from each other and from previously characterized carlaviruses at both the nucleotide and amino acid level, and thus represent separate species in the genus Carlavirus.

AB Clover yellow vein virus (ClYVV), Bidens mottle virus (BiMoV) and Apium virus Y (ApVY) were identified in Ammi majus in south Florida cut flower production areas in 2005 and/or 2007. To the best of our knowledge, these results are the first report of ClYVV and BiMoV infection of A. majus in North America and the first report of ApVY in North America. Common weeds in Florida are known reservoir hosts for ClYVV including white clover (Trifolium repens) and for BiMoV including Spanish needles (Bidens pilosa) and tropical soda apple (Solanum viarum). Detection of ClYVV and BiMoV in other ornamental crops in Florida suggests that these viruses pose a broader risk to ornamental production.

AB Many plant virus diseases cause significant losses in the production and quality of ornamental crops, are very difficult to control, and new diseases occur as different crops are introduced or grown in new areas. Many crops are susceptible to multiple viruses, each of which may cause serious economic losses, and infected plant material may not be acceptable for export. Growers have reported problems with previously unreported viruses in several economically important ornamental crop species exhibiting virus-like symptoms. Testing of various ornamental plants exhibiting mosaic, ringspot, or flower break symptoms with our potyviral broad-spectrum monoclonal antibody PTY-1 revealed that the causal agent might be a potyvirus. Electron microscopic examination of leaf dips or thin sections usually revealed the presence of potyvirus-like particles or potyviral cytopathology, respectively. The potyvirus group contains over 200 definitive and possible members which cause significant losses in many important agronomical and horticultural important crop species. Here we report the detection, cloning, sequencing and identity of potyviruses detected by PTY-1 in various ornamental plants. Total RNA extracts from symptomatic PTY-1 'positive' plants were used with potyvirus-specific primers in RT-PCR assays. The degenerate primers used for the genus Potyvirus direct the amplification of fragments from the 3' terminus of most potyviruses (including the coat protein gene and 3' NCR). The resultant PCR amplicons were cloned, sequenced and compared to potyvirus sequences in the international databases. Serological and pair-wise and phylogenetic sequence analysis revealed the identification of new potyviruses, including Tricyrtis virus Y in toad lily Tricyrtis formosana (in a mixed infection with Lily virus X potexvirus) and Omphalodes virus Y in Navelwort Omphalodes. Previously identified reoccurring potyviruses infecting Euphorbia (Euphorbia ringspot virus), Brugmansia (Columbian datura virus), Impatiens (Impatiens flower break virus), Osteospermum (Lettuce mosaic virus), Schizostylis (Bean yellow mosaic virus) and Spiranthes (Dasheen mosaic virus, Spiranthes mosaic virus 2 and 3 were also detected and confirmed.

AB The soybean genome assembly has been available since the end of 2008. Significant features of the genome include large, gene-poor, repeat-dense pericentromeric regions, spanning roughly 57% of the genome sequence; a relatively large genome size of similar to 1.15 billion bases; remnants of a genome duplication that occurred similar to 13 million years ago (Mya); and fainter remnants of older polyploidies that occurred similar to 58 Mya and >130 Mya. The genome sequence has been used to identify the genetic basis for numerous traits, including disease resistance, nutritional characteristics, and developmental features. The genome sequence has provided a scaffold for placement of many genomic feature elements, both from within soybean and from related species. These may be accessed at several websites, including http://www.phytozome.net, http://soybase.org, http://comparative-legumes.org, and http://www.legumebase.brc.miyazaki-u.ac.jp. The taxonomic position of soybean in the Phaseoleae tribe of the legumes means that there are approximately two dozen other beans and relatives that have undergone independent domestication, and which may have traits that will be useful for transfer to soybean. Methods of translating information between species in the Phaseoleae range from design of markers for marker assisted selection, to transformation with Agrobacterium or with other experimental transformation methods.

AB Phytophthora stem and root rot, caused by Phytophthora sojae, is one of the most destructive diseases of soybean [Glycine max (L.) Merr.], and the incidence of this disease has been increasing in several soybean-producing areas around the world. This presents serious limitations for soybean production, with yield losses from 4 to 100%. The most effective method to reduce damage would be to grow Phytophthora-resistant soybean cultivars, and two types of host resistance have been described. Race-specific resistance conditioned by single dominant Rps ("resistance to Phytophthora sojae") genes and quantitatively inherited partial resistance conferred by multiple genes could both provide protection from the pathogen. Molecular markers linked to Rps genes or quantitative trait loci (QTLs) underlying partial resistance have been identified on several molecular linkage groups corresponding to chromosomes. These markers can be used to screen for Phytophthora-resistant plants rapidly and efficiently, and to combine multiple resistance genes in the same background. This paper reviews what is currently known about pathogenic races of P. sojae in the USA and Japan, selection of sources of Rps genes or minor genes providing partial resistance, and the current state and future scope of breeding Phytophthora-resistant soybean cultivars.

DT Article
ID FIGITIDAE EUCOILINAE; CIRCUMSCRIPTION; EVOLUTION; GENUS
AB Wing interference patterns (WIPs) are a potentially rich source of taxonomic data. We surveyed a broad range of Cynipoidea (Hymenoptera) for the presence of these patterns. Further, we used phylogeny to investigate the evolutionary patterns of WIPs throughout the superfamily. We also documented that WIPs occur across nearly all species sampled, in both the hindwing and forewing; in many instances, the forewing WIP is carried over to the hindwing. Only Austrocynips mirabilis Riek lacked WIPs. Among species that possess WIPs, we were able to recognise four distinct categories: radiform (radiating), striatiform (longitudinally striate), campiform (continuous field) and galactiform (amorphous mixture of colours). Wing interference patterns are not found in infuscate wings or areas of infuscation on otherwise hyaline wings, and are reduced on large wings. Within Figitidae, WIPs are more phylogenetically conservative, especially at the tribal level: within Cynipidae the phylogenetic conservatism of WIPs is somewhat less clear, though all Synergini sampled had a very consistent WIPs. For certain genera, such as Ganaspidium and Andricus, WIPs may prove useful for species-level discrimination.

ID REPRODUCTIVE ISOLATION; ZEA; POPULATION; DIVERSITY; LOCUS
AB Gametophyte factors in maize (Zea mays L) mediate pollen-pistil interactions that confer preferential fertilization of some pistil genotypes by pollen carrying compatible alleles. Non-Mendelian segregation ratios caused by gametophyte factors have been observed in maize since the early 1920's. In this study, we mapped the gal locus by analyzing segregation distortion and QTL for seed set in recombinant inbred lines from the cross B73 x Hp301. The dent corn parent of this cross, B73, carries ga1, whereas the popcorn parent Hp301 carries the Ga1-s allele conferring preferential fertilization and cross-sterility. High density genotyping-by-sequencing markers were used to delineate the position of ga1 to a 2.6 Mbp region of the B73 reference sequence (AGP version 2). We also mapped ga1 based on its inheritance in backcross between W22 (ga1) and a near-isogenic line carrying Ga1-s on a chromosome segment introgressed from a popcorn variety. The chromosome blocks introgressed from popcorn into W22 were identified with a high-density SNP assay. We created simple sequence repeat markers targeting sequences linked to ga1 to track its inheritance in the W22 backcross populations. Recently, other researchers independently mapped ga1 in crosses of Chinese dent and popcorn lines, and we compared our results to theirs with reference to the B73 reference sequence. All lines of evidence were consistent, with the intervals containing ga1 among all studies overlapping in a 2.2 Mbp interval on chromosome 4 containing 13 predicted genes in the B73 reference sequence.

AB This study demonstrates sulfite pretreatment to overcome recalcitrance of lignocellulose (SPORL) for robust bioconversion of corn stalks. With only about 3% sodium bisulfite charge on corn stalks and 30 min pretreatment at temperature 180 degrees C, SPORL can achieve near complete cellulose conversion to glucose in 48h enzymatic hydrolysis. Sulfuric acid charge has great effect on SPORL pretreatment. Enzymatic cellulose conversion of substrate increased with the increase in acid charge under the studied conditions. Bisulfite with different counter-ions can be used in the SPORL. Magnesium as counter ion was found to be more effective on enzymatic hydrolysis of substrate than sodium or ammonium.

AB Wild emmer wheat (Triticum dicoccoides Korn ex Asch. & Graebn.) Thell. is the allotetraploid (2n=4x=28; genome BBAA) progenitor of cultivated wheat. It is fully compatible with the tetraploid (BBAA) durum wheat (Triticum durum), and can be crossed with the hexaploid (2n=6x=42; BBAADD) wheat (Triticum aestivum). In the Fertile Crescent, the centre of origin and centre of diversity of wild emmer wheat, the wild progenitor exhibits a wide phenotypic and genotypic variation and displays a rich adaptive genetic diversity which is ecologically and genetically structured as an "archipelago." The fertile hybrids between wild emmer wheat and domesticated durum wheat point to the early, and probably current, extensive gene flow that must have enriched the genetic structure of both subspecies in the Fertile Crescent. Specific alleles and allele combinations predominate, at the macro-and microgeographic scales, as co-adaptive blocks of genes adapted to diverse biotic and abiotic stresses. Wild emmer wheat is recognized as a source of genes for agronomically important traits. These include genes for large spike and grain size, high grain and protein yield, desirable composition of storage proteins, photosynthetic yield, herbicide response, salt tolerance, drought tolerance, disease (leaf rust, stripe rust, powdery mildew, and soil-born mosaic virus) resistance, profuse tillering, and genes for other quantitative traits. For millennia, the vast genetic diversity in wild emmer wheat must have contributed to the spatially and temporally sustainable wheat production as a major component of dynamic cropping systems in the Fertile Crescent. With the advent of, and easy access to, molecular genetics and breeding tools, wild emmer wheat is expected to contribute the full range of its diversity in quantitative and qualitative traits for a more globally sustainable wheat production. It is expected that the current and future detailed records of phenotypes and genotypes and their spatio-temporal variation patterns in the Fertile Crescent will form an integral part of a relational database that can serve future strategies for in situ conservation, collection, evaluation, and utilization by wheat geneticists and breeders.

AB Radiations from different electrical devices cause electromagnetic interference which will influence the performance realization of other electromagnetic device and cause the health concerns. The aluminum plates were then used to develop wood electromagnetic shielding composites by laminating with the plywood. Their static modulus of elasticity and electromagnetic shielding effectiveness of the composites with different thickness and position of aluminum plates were evaluated. The results showed that the strength of composites were improved by laminating the aluminum plates on the surface. The electromagnetic shielding performance of the composites were increased by the design of the multilayer and sandwich shielding structure. Again, It was also found that the composites made by laminating two aluminum plates (1mm, in the middle or on the surface) had a better shielding effectiveness (60 dB to 92 dB, 60 dB to 106 dB, Ranged from 1 GHz to 10 GHz) and met the requirement for a commercial electromagnetic shielding building product.

AB Serum proteins and peptides have potential as biomarkers since they form the structural and functional basis of tissues and are involved in metabolic and regulatory processes. Changes in their profiles or their breakdown products have been of interest as potential biomarkers. Tibial dyschondroplasia (TD) and femoral head separation (FHS) are two metabolic skeletal problems in poultry that cause lameness. The objective of this study was to identify serum peptide changes associated with lameness in poultry that may be predictive of the disease and may help in eliminating these hereditary defects from the genetic pool. Serum peptides were extracted from six-wk-old chickens with or without the above leg problems using C-18 magnetic beads and analyzed by MALDI-TOF mass spectrometry. Differentially expressed peptides were analyzed in the m/z range of 1,000-10,000 using ClinproToolTM software. Twenty two peaks from TD and 20 from FHS affected chickens were compared with their respective controls. The spectral peaks were identified using mass spectrometry followed by a data base search. Some of the peptides identified were hemostasis associated breakdown products. No differentially expressed peptide was detected in FHS but a peptide with m/z 5308.1 was elevated in chickens with TD (p <= 0.05). It was identified as a fragment of alpha 1 type-XI isoform 1. Type XI collagen is a cartilage specific extracellular matrix protein that is involved in the organization of other collagens and maintains extracellular matrix integrity. Its breakdown product may indicate cartilage degeneration in tibial dyschondroplasia thus may serve as a surrogate marker for this problem.

AB Pinus parviflora Siebold et Zucc. on Ulleung Island, Korea, has been proposed to be more closely related to P. armandii Franch. because both have long leaves and seeds that are either wingless or have very short wings. Randomly amplified polymorphic DNA (RAPD) markers using nine primers and sequence analysis of the trnG gene and the matK gene and morphological characteristics of seeds and cones were used to assess the genetic relatedness of this taxon on Ulleung Island with P armandii in China and P parviflora in Japan. This current study showed that Pin us armandii from China, R parviflora from Japan, and R parviflora populations of Ulleung Island formed distinct groups that were separated from each other. R parviflora from Ulleung Island grouped with R parviflora from Japan, rather than P armandii from China based on the RAPD dendrogram and SNPs in matK. It is believed that R parviflora on Ulleung Island is genetically well differentiated, indicating limited gene flow from Japan, although cones and seeds of P parviflora on Ulleung Island are more similar to var. parviflora in southern Japan than R armandii in central China. It seems that the entities that comprise parviflora exhibit widely overlapping ranges in morphological attributes except Leaf length.

AB Microorganisms able to infect and kill insect pests, metabolites from plants and microorganisms, and transgenic crops are biotechnologically-derived products that are being promoted for use to control insect pests in lue of chemical insecticides. Products based on these technologies effectively control important pests of health, food and agriculture systems. Among products classified as bioinsecticides, entomopathogenic microorganisms, organism metabolites and transgenic seeds are considered as biotechnology derived agents for insect pest control. There are many bioinsecticides that are efficacious and currently available as commercial products in the agroindustry market. This review describes background of the general categories of bioinsecticides and lists current bioinsecticide products available for use to control insect pests.

TI Recycling of Pentachlorophenol-Treated Southern Pine Utility Poles. Part
I: Preservative Retention and Mechanical Properties
SO FOREST PRODUCTS JOURNAL

DT Article
ID WOOD PRODUCTS; SERVICE; LIFE
AB Reusing decommissioned wood utility poles will extend the service life of the treated wood and offer economic and ecological advantages. The aim of this study was to evaluate pentachlorophenol (penta) retention and distribution, together with physical and mechanical properties of penta-treated southern pine (Pinus spp.) utility poles for reuse and recycling. Fifteen penta-treated decommissioned southern pine utility poles and pole sections were collected and studied. As expected, residual penta retention decreased from outside to the pith and from the top to the bottom of the poles. Of the 15 poles tested, penta retention averages at the two outer test zones varied from 3.9 to 5.6 kg/m(3), while the overall penta retention averages of these poles varied from 3.2 to 5.4 kg/m(3). The modulus of rupture (MOR) and modulus of elasticity (MOE) averages of the 15 poles and pole sections were 33.7 and 68.1 percent lower, respectively, than the published MOR and MOE values of virgin loblolly pine (Pinus taeda) wood. MOR and MOE varied in an M shape across the diameters of the poles due to surface aging. The shallow, aged surface layers, particularly of older poles, had low strength and relatively high penta retention, suggesting that surface layers should be removed from the recycled poles. However, most of the remaining pole portions had medium to high strength and were therefore reusable for other products.

AB The Asian longhorned beetle, Anoplophora glabripennis, is an invasive pest that poses a serious threat to many species of North American hardwoods. An efficacious heat treatment schedule for this insect is crucial to allow wood to move from quarantined areas in the United States. A series of experiments were conducted using naturally infested trees to evaluate the International Standards for Phytosanitary Measures Rule No. 15 heat treatment schedule (56 degrees C core temperature for 30 min) on overwintering A. glabripennis larvae. Results indicate that this treatment is effective, as no overwintering larvae were observed to survive. Overwintering larval stage, heating rates, oven load factors, and treatments are reported.

TI A New Slash Bundling Concept for Use in a Southern US Logging System
SO FOREST PRODUCTS JOURNAL

DT Review
ID PRODUCTIVITY
AB John Deere's biomass bundler unit is an effective machine for harvesting forest residues, which can be used as a source of fuelwood and/or a feedstock for biofuel production. This project explored an avenue that could supply a promising source of readily available energy in southeastern forested lands. Typical southern harvesting operations consist of whole-tree harvesting in which trees are felled and then skidded to a landing. Limbs and tops are usually either deposited over the landscape or piled in windrows. The biomass bundler captures the otherwise nonmerchantable material and maximizes the marketability of the entire tree. In order to reduce costs, maximize efficiency, and implement the bundler in a tree-length harvesting operation, this project tested a prototype harvesting system. This venture (1) adapted the John Deere B380 bundler unit to a motorized trailer, (2) designed an optimum landing configuration, and (3) conducted a productivity study of the bundler unit. The unit produced 13.2 tonnes per productive machine hour (PMH; 14.6 tons/PMH) of 250-cm bundles and 14.9 tonnes/PMH (16.4 tons/PMH) of 350-cm bundles, assuming minor delays at a cost of $12.50 to $14.20/tonne ($11.25 to $12.85/ton).

TI Shading Aboveground L-Joint and Lap-Joint Tests: Comparison of White
Pine and Sugar Maple Test Assemblies
SO FOREST PRODUCTS JOURNAL
LA English
DT Review
ID UNTREATED WOOD; DECAY
AB Five-year performance ratings are presented for two types of untreated, uncoated wood joints (L and lap) in aboveground tests under shaded conditions. The effect of shading on moisture entrapment in pine and maple L and lap joints was evaluated in a moderate decay zone (Madison, Wisconsin). Variations were observed between wood species, visual ratings, joint type, moisture content readings, and fungal growth on the specimens. Representative fungal fruiting bodies were identified as members of the Peniophorella praetermissa species complex by microscopic and DNA analyses. After 5 years, the highest average rating (indicative of most severe deterioration) occurred in white pine L-joint specimens followed by maple lap joints and maple L joints. Pine and maple L-joint specimens demonstrated considerably lower rating variation between specimens compared with lap-joint specimens. White pine lap joints shaded with a tarp had lower average moisture content but showed similar average ratings to pine lap joints shaded by a tree. Regardless of the shading method, white pine lap joints had the lowest average decay rating. Under shaded conditions in a moderate decay zone, untreated and uncoated L-joint performance was notably more uniform from specimen to specimen than lap-joint performance following 5 years of outdoor exposure. A single-point moisture content taken at the time of inspection was not a reliable indicator of the degree or rate of decay for aboveground joint test assemblies evaluated in this study. Likewise, uniform specimen wetting or drying is not predictable under shaded conditions.

AB The influences of temperature, heating rate, purge gas type, and flow rate on the yield of chars produced from pyrolyzing southern pine chips were investigated. Pyrolysis temperatures were between 450 degrees C and 1,000 degrees C, with heating rates of 0.5 degrees C/min, 1.0 degrees C/min, 1.0 degrees C/min, 30 degrees C/min, 50 degrees C/min, and 100 degrees C/min. Purge gases, nitrogen (N-2), hydrogen (H-2), and N-2-H-2 mixture (10% H-2), were used at flow rates from 100 to 1,000 mL/min. Pine char yield decreased as temperature, heating rate, or purge gas flow rate increased. Two regions with significantly different decrease rates of pine char yield can be identified for temperature or heating rate as they increase. The yield decrease rate turning points were 550 degrees C and 10 degrees C/min for yield-temperature and yield-heating rate charts, respectively. The pine char yield was lowest when hydrogen was the purge gas and highest with nitrogen.

ID WATER-CONTENT; STORAGE; TREES; SOIL; STEM
AB The responsible usage of water by facilities that rely on wet log storage in the southern United States has become an issue of great importance as restrictions on water usage have grown in recent years. In order to learn about the dynamics of moisture content in wet-stored logs over time, it is necessary to conduct continuous monitoring of log piles. Time domain reflectometry (TDR) is a method that current research has shown to have potential for use in this area. In this study, TDR probes of three lengths (75, 100, and 125 mm) were systematically inserted into 39 saturated bolts of Pinus taeda L., and both TDR and moisture content measurements were taken nine times over a period of 16 days as the bolts air dried. The samples were then oven dried, and measurements were taken three more times during that process. TDR readings from the 125-mm probes had the strongest relationship (R-2 = 0.9426) with moisture content measurements. This result indicates TDR readings are sufficiently correlated with moisture content to accurately predict moisture variation over time and can be used to learn how water application and other factors affect the moisture content of wet-stored logs.

AB We describe and illustrate two techniques for enhancing curatorial and processing efficiency as it pertains to parasitic Hymenoptera (Chalcidoidea, Cynipoidea). These techniques were developed in response not only to the massive number of parasitoids that have been acquired through various biodiversity studies, but also the difficulty in mobilizing the human resources to curate this material. The first technique uses small, crystal polystyrene boxes with tight-fitting lids to store dehydrated specimens prior to mounting. Locality information is affixed to the box and specimens are spread in a layer for ease of examination by researchers. Solutions for managing static electricity within the specimen boxes are discussed. The second involves a vacuum pump connected to a funnel with a filtration membrane and flask apparatus to rapidly dehydrate hard-bodied parasitoids (Figitidae) that are not subject to collapse during air-drying.

AB There are numerous options for monitoring ATP synthesis in chloroplasts using isolated thylakoid membranes, intact chloroplasts, and even whole leaves. Currently, the most commonly used method employs isolated thylakoids coupling the synthesis of ATP to light emission from luciferin in a reaction catalyzed by luciferase. The luciferin-luciferase assay can be highly sensitive and is a direct measure of ATP. Another direct measurement of ATP is the incorporation of P-32 into ATP, which, while more technically difficult, has the advantage over the luciferin-luciferase assay of being able to distinguish newly synthesized from total ATP. The phosphorylation of ADP results in a net decrease in pK(a) (acid disassociation constant) between the reactants and the product ATP, resulting in an increase in the pH of the assay media, which can be used as a convenient, continuous measurement of ATP synthesis. The formation of Delta mu(H+) across the thylakoid membrane and its concomitant dissipation as ATP is synthesized can be measured by an electrochromic absorption band shift (ECS) of thylakoid pigments measured at 518 nm (Witt, Biochim. Biophys. Acta 505:355-427, 1979; Petty and Jackson, Biochim. Biophys. Acta: Bioenergetics 547:463-473, 1979). The first-order decay time of the ESC can be used to estimate the rate of ATP synthesis providing a noninvasive, indirect method for measuring ATP synthase activity that can be used with intact leaves.

AB This chapter discusses the major causes of postharvest losses in tropical and subtropical fruits due to fungal pathogens. First, the etiology, biology and environmental and horticultural factors that are involved in infection and development of decay are reviewed. Here, understanding the relationship between production conditions and the postharvest handling chain is crucial for improving fruit quality. Details on the host-pathogen interactions of major pathogens of tropical and subtropical fruits and their modes of infection are provided. Special emphasis is given to Colletotrichum as it has a very wide host range and causes extensive postharvest losses in many fruits. Information about natural (constitutive and induced) fruit defense mechanisms in major tropical and subtropical fruit is also discussed. The chapter addresses current control strategies based mainly on the use of synthetic fungicides but also includes information on safer alternatives.

AB International trade in tropical and subtropical fruits has become increasingly important, but phytosanitary restrictions continue to limit its growth. Phytosanitary or quarantine treatments are often required to disinfest host commodities of economically important arthropod pests before they are moved through market channels within or between countries to areas where the pest does not occur. This chapter describes some of the important quarantined pests, as well as some of the treatments that can be used for their control and the effects of the commercially developed or potential insect quarantine treatments and systems on the quality of tropical and subtropical fruits, thus allowing the evaluation of the potential of the commercial application of these treatments or systems on the basis of their effect on fruit quality.

AB This chapter describes past outbreaks, potential routes of contamination for specific pathogens, potential interventions, and operational procedures associated with tropical and subtropical fruits. Various preharvest sources can result in contamination of fruits. Survival and growth of pathogens on whole and fresh-cut fruits are variable depending on the biotic and abiotic factors such as indigenous microorganisms, storage temperature and humidity, etc. The effectiveness of chemical, physical, and biological treatments designed to eliminate pathogens on these fruits can be limited by the surface topography, hydrophobicity, organic material present on fruits, and other confounding factors. Integrated food safety management programs, and pathogen prevention and decontamination approaches in the supply chain must be utilized to make tropical and subtropical fruits safe for consumption.

AB Rambutans (Nephelium lappaceum) are exotic tropical fruit with a relatively short shelf life. Fresh rambutans are bright red or yellow at harvest, but the peel color and spinterns darken during storage. Postharvest diseases also limit the successful marketing and export of this specialty fruit. Pericarp browning can be delayed when the fruit are held at 8-12 degrees C and 95% relative humidity, depending on cultivar. The use of modified atmosphere packaging or enhanced CO2 atmospheres (9-12%) can also maintain the visual quality of rambutans. Integrated preharvest and postharvest practices that achieve disease control while reducing desiccation and browning are needed to extend rambutan shelf life beyond two weeks.

AB EARLY RECOVERY OF SUBTROPICAL DRY FOREST IN SOUTHWESTERN PUERTO RICO Tree cover and species composition were surveyed in 1998, 2003, and 2010 after the elimination of grazing and fire on the lower 32 hectares of the Tinaja tract at Laguna Cartagena National Wildlife Refuge in south-western Puerto Rico. Surveys of the secondary subtropical dry forest showed that stems increased 3.9 times, trees 6.7 times, basal area 3.3 times, and biomass 4.4 times between 1998 and 2010. Notable differences occurred by site. Greater numbers of stems and trees, greater basal areas, and usually biomass were tallied on 10 plots along the southern boundary closer to residual tree cover than on the northern 22 plots in all three years of measurement. Four plots situated in arroyos and one plot along a fence-line also showed greater values when compared to the respective mean values for all 32 plots on lower Tinaja. Other major trends between 1998 and 2010 were: exotics increased from 70 to 84% of the stems and from 70 to 86% of the trees; the ratio of stems to trees declined from 2.3 to 1.3; Leucaena leucocephala (Lam.) DeWit increased from 7 to 53% of the stems and from 14 to 64% of the trees; Pilosocereus royenii (L.) Byles & Rowley decreased from 10 to 2% of the stems and from 7 to 1% of the trees, largely due to attack by the cactus mealybug, Hypogeococcus pungens; and tree species richness increased from 30 to 34.

AB The fig (Ficus carica L.), one of the first cultivated trees in the world, is grown in many parts of the world with moderate climates. Figs are eaten dry and fresh; however, as fresh figs are highly perishable they are largely consumed near production areas. Figs are nutritious fruits rich in fiber, potassium, calcium, and iron. Fresh figs are highly sensitive to physical damage, and susceptible to postharvest decay infections. Preharvest and postharvest conditions are very important to improve fruit quality and postharvest life. At this point, reducing postharvest losses and developing global fresh fig marketing is a big challenge for plant breeders, physiologists and postharvest technologists.

AB From field-scale measurements to global climate simulations and remote sensing, the growing body of very large and long time series Earth science data are increasingly difficult to analyze, visualize, and interpret. Data mining, information theoretic, and machine learning techniques-such as cluster analysis, singular value decomposition, block entropy, Fourier and wavelet analysis, phase-space reconstruction, and artificial neural networks-are being applied to problems of segmentation, feature extraction, change detection, model-data comparison, and model validation. The size and complexity of Earth science data exceed the limits of most analysis tools and the capacities of desktop computers. New scalable analysis and visualization tools, running on parallel cluster computers and supercomputers, are required to analyze data of this magnitude. This workshop will demonstrate how data mining techniques are applied in the Earth sciences and describe innovative computer science methods that support analysis and discovery in the Earth sciences.

AB Identification of geographic ecoregjons has long been of interest to environmental scientists and ecologists for identifying regions of similar ecological and environmental conditions. Such classifications are important for predicting suitable species ranges, for stratification of ecological samples, and to help prioritize habitat preservation and remediation efforts. Hargrove and Hoffman [1, 2] have developed geographical spatio-temporal clustering algorithms and codes and have successfully applied them to a variety of environmental science domains, including ecological regionalization; environmental monitoring network design; analysis of satellite-, airborne-, and ground-based remote sensing, and climate model-model and model-measurement intercomparison. With the advances in state-of-the-art satellite remote sensing and climate models, observations and model outputs are available at increasingly high spatial and temporal resolutions. Long time series of these high resolution datasets are extremely large in size and growing. Analysis and knowledge extraction from these large datasets are not just algorithmic and ecological problems, but also pose a complex computational problem. This paper focuses on the development of a massively parallel multivariate geographical spatio-temporal clustering code for analysis of very large datasets using tens of thousands processors on one of the fastest supercomputers in the world.

AB We investigate methods for geospatiotemporal data mining of multi-year land surface phenology data (250 m(2) Normalized Difference Vegetation Index (NDVI) values derived from the Moderate Resolution Imaging Spectrometer (MODIS) in this study) for the conterminous United States (CONUS) as part of an early warning system for detecting threats to forest ecosystems. The approaches explored here are based on k-means cluster analysis of this massive data set, which provides a basis for defining the bounds of the expected or "normal" phenological patterns that indicate healthy vegetation at a given geographic location. We briefly describe the computational approaches we have used to make cluster analysis of such massive data sets feasible, describe approaches we have explored for distinguishing between normal and abnormal phenology, and present some examples in which we have applied these approaches to identify various forest disturbances in the CONUS.

AB One of the principal recurring themes in the search for effective responses to the continuing public health and economic problems caused by Salmonella contamination of eggs concerns reducing the susceptibility of egg-laying chickens to infection. Decreasing the overall prevalence or level of Salmonella infection among commercial laying flocks has the potential to exert a corresponding influence on the likelihood that contaminated eggs will be produced and marketed. This chapter considers both the capabilities and limitations of three leading options for reducing the susceptibility of laying hens to Salmonella: vaccination to induce immunity, genetic selection for naturally occurring resistance to infection, and gastrointestinal colonization control.

AB Vegetation water content (VWC) is a useful parameter in agriculture, forestry and hydrology studies. It is particularly valuable in accounting for vegetation effects in retrieving soil moisture using microwave radiometers. Microwave vegetation indices (MVIs) reflect information of the whole vegetation canopy. They may provide a mean for estimating VWC. In this study, a methodology for retrieving VWC using MVIs is presented. Coefficients of the relationship were found to be dependent only on a vegetation structure parameter. The methodology was tested with brightness temperature observations at C and X bands collected over a growing season of cotton. It was found that results compared well with field observations of VWC measured during the early growing season. The methodology should be useful for vegetation monitoring and soil moisture retrieval over low vegetated areas.

AB This paper investigates tree scattering effects at L-band by using a first-order radiative transfer (RT) model and truck-based measurements of brightness temperature over natural conifer stands to assess the performance of the tau - omega (tau-omega) model, a zero-order RT solution, over forest canopies. The tau-omega model accounts for vegetation effects in terms of "effective" vegetation parameters (single-scattering albedo and vegetation opacity) which represent the canopy as a whole. This approach inherently ignores multiple-scattering effects and it thus has a limited validity depending on the level of scattering within the canopy. The fact that the scattering from large forest components such as branches and trunks is significant at L-band requires that retrieved vegetation parameters be evaluated (compared) with their theoretical definitions to provide better understanding of these parameters in the soil moisture (SM) retrievals over moderately to densely vegetated landscapes. In this paper, the tau-omega model is fitted to a first-order RT model with an "effective" albedo assuming that "effective" vegetation optical depth is same as the "theoretical" opacity [1]. The "effective" albedo is found to be less than half of the "theoretical" one, which is generally around 0.5-0.6 for tree canopies at L-band. The "effective" albedo differs from the albedo of a single forest canopy element and becomes a global parameter which depends on all the processes taking place within the canopy including multiple-scattering and ground reflection.

AB Soil Moisture Active Passive (SMAP), a proposed mission in support of the Earth Science Decadal Survey, conducted a field campaign in June 2010 to support algorithm development. As part of the experiment in situ soil moisture measurements were made over a two week period in which multiple UAVSAR flights were conducted. Repeat-pass polarimetric-interferometric data generated from these flights were analyzed to see if phase changes could be correlated with soil moisture changes. Also, we compared the data to that predicted by simple surface scattering models and showed moderate agreement with the Oh model [4].

AB The Soil Moisture Active Passive (SMAP) mission is one of the first-tier satellite missions recommended by the U. S. National Research Council Committee on Earth Science and Applications from Space. The SMAP mission 1 is under development by NASA and is scheduled for launch late in 2014. The SMAP measurements will allow global and high-resolution mapping of soil moisture and its freeze/thaw state at resolutions from 3-40 km. These measurements will have high value for a wide range of environmental applications that underpin many weather-related decisions including drought and flood guidance, agricultural productivity estimation, weather forecasting, climate predictions, and human health risk. In 2007, NASA was tasked by The National Academies to ensure that "emerging scientific knowledge is actively applied to obtain societal benefits" by broadening community participation and improving means for use of information. SMAP is one of the first missions to come out of this new charge, and its Applications Plan forms the basis for ensuring its commitment to its users. The purpose of this paper is to outline the methods and approaches of the SMAP applications activity, which is designed to increase and sustain the interaction between users and scientists involved in mission development.

AB SMOS observations provide an opportunity to develop a testbed for the evaluation of different SMAP algorithm options. The use of real-world global observations will help in the development and selection of different land surface parameters and ancillary observations needed for the soil moisture algorithms. In this study, SMOS observations were used with one soil moisture retrieval algorithm and the results were evaluated using in situ soil moisture measurements. The SMOS soil moisture product, which exploits multiple incidence angle observations, compares well with the ground-based observations (RMSE 0.043 m(3)/m(3) (ascending) and 0.047 m(3)/m(3) (descending)). The alternative SMAP compatible algorithm also performed well (RMSE 0.040 m(3)/m(3) (ascending) and 0.043 m(3)/m(3) (descending)). Although preliminary, these initial results are encouraging for the potential of SMAP to meet its required soil moisture accuracy.

ID ATMOSPHERIC CORRECTION; MODIS DATA
AB NDVI maps have been proven valuable in providing a spatially complete view of crop's vegetation condition, which manifests disastrous events such as massive flood and drought. It is virtually impossible to obtain from ground survey data. This paper uses NASA MODIS 250m resolution, daily surface reflectance data for crop condition monitoring. The NDVI provides an absolute metrics for vegetation condition. However, a relative measurement of the current vegetation condition against a reference vegetation condition is critical for understanding, interpreting and quantifying the current vegetation condition. In this paper, a new NDVI based vegetation condition index is presented to measure the vegetation condition with respect to the "normal condition", which is characterized by historical average. The proposed new vegetation condition index is empirically compared with several other vegetation indices to evaluate its effectiveness. Its advantages and utility for crop vegetation condition measurement are evidenced by the preliminary results.

AB The Nile basin River system spans 3 million km(2) distributed over ten nations. The eight upstream riparian nations, Ethiopia, Eretria, Uganda, Rwanda, Burundi, Congo, Tanzania and Kenya are the source of approximately 86% of the water inputs to the Nile, while the two downstream riparian countries Sudan and Egypt, presently rely on the river's flow for most of the their needs. Both climate and agriculture contribute to the complicated nature of Nile River management: precipitation in the headwaters regions of Ethiopia and Lake Victoria is variable on a seasonal and inter-annual basis, while demand for irrigation water in the arid downstream region is consistently high. The Nile is, perhaps, one of the most difficult trans-boundary water issue in the world(1) , and this study would be the first initiative to combine NASA satellite observations with the hydrologic models study the overall water balance in a comprehensive manner. The cornerstone application of NASA's Earth Science Research Results under this project are the NASA Land Data Assimilation System (LDAS)(2) and the USDA Atmosphere-Land Exchange Inverse (ALEXI)(3) model. The end-users such as Regional Center for Mapping of Resources for Development (RCMRD, Nairobi, Kenya), Eastern Nile Technical Regional Office (ENTRO, Addis Ababa, Ethiopia), Ethiopian and Kenya Meteorological and Famine Early Warning System Network (FEWSNet) will be the eventual benefactors of this work.

AB Date palm (Phoenix dactylifera L) belongs to the genus Phoenix which is distributed throughout the tropical and subtropical areas of South Asia and Africa. The species are dioecious and the fruits are drupes of varying sizes. P dactylifera apparently originated in the area near the present Iraq and Iran, was domesticated in ancient times and spread into adjacent regions having appropriate climates. Primitive date palms were probably similar to modern date palms but with smaller, less palatable fruits. Genetic diversity of date palms in the center of origin is threatened by such factors as development, desertification, ecosystem change and salinization. Examination of traditional oasis culture of date palms suggests that many of the trees in those oases were khalts or mixtures of seedlings. Propagation by offshoots was probably less common but was important in introducing superior varieties from other areas. In general, populations of date palms appear to be mixtures of khalts with some elite named varieties present. The introduction of elite varieties, whether from other oases or via tissue culture, may contribute to the genetic erosion of R dactylifera in traditional oases. Farmers should be encouraged to continue cultivating traditional varieties in the oasis cultures, but ex-situ collections of date palms should also be established in order to facilitate access and utilization of date palm germplasm. Work is needed to better characterize and evaluate date palm germplasm and to understand the genetic basis for the traits expressed. This is vital to a rational and successful utilization of date palm genetic resources.

AB The use of near infrared (NIR) diffuse reflectance spectroscopy for the estimation of basic density and moisture content of loblolly pine (Pinus taeda L.) logs was explored. A total of 219 wood disks representing the large and small ends of 146 merchantable logs 4.87m in length, ranging in age from 13 years to 19 years, were analysed. NIR spectra were obtained from the transverse surface of the disks when the wood was green using a Foss XDS NIR System coupled with a Smart Probe Analyser. Each disk was divided into four quadrants and two spectra were collected per quadrant (one representing juvenile wood and one mature wood). NIR calibration models were fitted using pre-processed spectra with multiplicative scatter correction and the dimensionality of the models was kept constant for comparison purposes. Successful models based on an average of all spectra collected from both ends of the logs were obtained for basic density (R-C(2)=0.84) and moisture content (R-C(2)=0.85) using nine factors for both properties. The predictive ability of the calibrations was acceptable, with mean square errors of 22.8 kg m(-3) for basic density and 2.1% for moisture content. It was found that the number of spectra per disk could be reduced to four readings but further reductions increased prediction errors considerably. Calibration models based only on spectra collected from one of the log ends were also examined. Using large-end diameter spectra only, the fit statistics for basic density models fell to R-C(2)=0.76 for (eight spectra) and R-C(2)=.0.71 (four spectra). Similarly, the fit statistics for moisture content calibrations dropped to R-C(2)=0.76 for (eight spectral and R-C(2)=0.72 (four spectral. Calibrations based only on small-end diameter spectra were considerably weaker than those based on large-end diameter spectra.

AB The chemical composition and fatty acid content of both white sorghum hybrids and pure lines grown in various areas of the world were studied. Various attributes were investigated including moisture, protein, carbohydrate, dietary fiber, fat contents, and fatty acid composition. Slight variations in both protein and in fiber contents were observed among cultivars. Linoleic, oleic and palmitic were the most abundant fatty acids in all samples with little difference in their percentage content among the cultivars. Enzyme-linked immunosorbent assays (ELISA) demonstrated, for all sorghum flours analyzed, the absence of toxic protein sequences for celiac patients. The present results demonstrate that food-grade sorghum varieties are potentially able to be grown in Mediterranean countries in addition to regions where sorghum has been traditionally produced, i.e. either in arid tropical and sub-tropical regions of Africa and Asia or in dry regions of America.

AB Tomato ripening is a highly coordinated developmental process that coincides with seed maturation. Regulated expression of thousands of genes controls fruit softening as well as accumulation of pigments, sugars, acids, and volatile compounds that increase attraction to animals. A combination of molecular tools and ripening-affected mutants has permitted researchers to establish a framework for the control of ripening. Tomato is a climacteric fruit, with an absolute requirement for the phytohormone ethylene to ripen. This dependence upon ethylene has established tomato fruit ripening as a model system for study of regulation of its synthesis and perception. In addition, several important ripening mutants, including rin, nor, and Cnr, have provided novel insights into the control of ripening processes. Here, we describe how ethylene and the transcription factors associated with the ripening process fit together into a network controlling ripening.

TI The wildland fire emission inventory: western United States emission

AB Biomass burning emission inventories serve as critical input for atmospheric chemical transport models that are used to understand the role of biomass fires in the chemical composition of the atmosphere, air quality, and the climate system. Significant progress has been achieved in the development of regional and global biomass burning emission inventories over the past decade using satellite remote sensing technology for fire detection and burned area mapping. However, agreement among biomass burning emission inventories is frequently poor. Furthermore, the uncertainties of the emission estimates are typically not well characterized, particularly at the spatio-temporal scales pertinent to regional air quality modeling. We present the Wildland Fire Emission Inventory (WFEI), a high resolution model for non-agricultural open biomass burning (hereafter referred to as wildland fires, WF) in the contiguous United States (CONUS). The model combines observations from the MODerate Resolution Imaging Spectroradiometer (MODIS) sensors on the Terra and Aqua satellites, meteorological analyses, fuel loading maps, an emission factor database, and fuel condition and fuel consumption models to estimate emissions from WF.
WFEI was used to estimate emissions of CO (ECO) and PM2.5 (EPM2.5) for the western United States from 2003-2008. The uncertainties in the inventory estimates of ECO and EPM2.5 (u(ECO) and u(EPM2.5), respectively) have been explored across spatial and temporal scales relevant to regional and global modeling applications. In order to evaluate the uncertainty in our emission estimates across multiple scales we used a figure of merit, the half mass uncertainty, (u) over tilde (EX) (where X = CO or PM2.5), defined such that for a given aggregation level 50% of total emissions occurred from elements with u(EX) < <(u)over tilde>(EX). The sensitivity of the WFEI estimates of ECO and EPM2.5 to uncertainties in mapped fuel loading, fuel consumption, burned area and emission factors have also been examined.
The estimated annual, domain wide ECO ranged from 436 Gg yr(-1) in 2004 to 3107 Gg yr(-1) in 2007. The extremes in estimated annual, domain wide EPM2.5 were 65 Gg yr(-1) in 2004 and 454 Gg yr(-1) in 2007. Annual WF emissions were a significant share of total emissions from non-WF sources (agriculture, dust, non-WF fire, fuel combustion, industrial processes, transportation, solvent, and miscellaneous) in the western United States as estimated in a national emission inventory. In the peak fire year of 2007, WF emissions were similar to 20% of total (WF + non-WF) CO emissions and similar to 39% of total PM2.5 emissions. During the months with the greatest fire activity, WF accounted for the majority of total CO and PM2.5 emitted across the study region. Uncertainties in annual, domain wide emissions was 28% to 51% for CO and 40% to 65% for PM2.5. Sensitivity of u(ECO) and u(EPM2.5) to the emission model components depended on scale. At scales relevant to regional modeling applications (Delta x = 10 km, Delta t = 1 day) WFEI estimates 50% of total ECO with an uncertainty < 133% and half of total EPM2.5 with an uncertainty < 146 %. (u) over tilde (ECO) and (u) over tilde (EPM2.5) are reduced by more than half at the scale of global modeling applications (Delta x = 100 km, Delta t = 30 day) where 50% of total emissions are estimated with an uncertainty < 50% for CO and < 64% for PM2.5. Uncertainties in the estimates of burned area drives the emission uncertainties at regional scales. At global scales (u) over tilde (ECO) is most sensitive to uncertainties in the fuel load consumed while the uncertainty in the emission factor for PM2.5 plays the dominant role in (u) over tilde (EPM2.5). Our analysis indicates that the large scale aggregate uncertainties (e. g. the uncertainty in annual CO emitted for CONUS) typically reported for biomass burning emission inventories may not be appropriate for evaluating and interpreting results of regional scale modeling applications that employ the emission estimates. When feasible, biomass burning emission inventories should be evaluated and reported across the scales for which they are intended to be used.

AB Zeolite minerals may improve nitrogen availability to plants in soil and reduce losses to the environment. A study was conducted to determine the influence of clinoptilolite (CL) on nitrogen (N) mineralization from solid dairy manure (224 kg N ha(-1)) in a sandy soil. Clinoptilolite was added to soil at six rates (0 to 44.8 Mg CL ha(-1)), each sampled during 11 sampling dates over a year. Over time, nitrate (NO3)-N increased, ammonium (NH4)-N decreased, but total inorganic N increased. Clinoptilolite did not influence the nitrification rates of initial manure NH4-N or mineralization of organic N (ON) over time. It is possible that adsorption of manure-derived potassium (K) outcompeted the NH4-N for CL exchange sites. The ON concentration was constant up to 84 days and then decreased by approximately 18% over the remaining time of the study across all treatments. Clinoptilolite use in this sandy soil did not alter mineralization of N from dairy manure.

AB This work tested the hypothesis that E. coli survival after streambed sediment inoculation does not differ significantly from survival in the same sediment after re-inoculation. The E. coli O157:H12 survived in two sediments with markedly different particle size distributions and organic matter contents in one-month-long experiments in flow-through chambers at 14 degrees C and 23 degrees C.The inactivation rates after re-inoculation were smaller than after inoculation; the differences were significant (P < 0.1) in two of four experiments. This study suggests that E. coli O157:H12 was able to adapt to the sediment environment so that its survival after re-inoculation improved.

PEATLANDS
AB Peatlands occupy a relatively small fraction of the Earth's land area, but they are a globally important carbon store because of their high carbon density. Undisturbed peatlands are currently a weak carbon sink (similar to 0.1 Pg C y(-1)), a moderate source of methane (CH4; similar to 0.03 Pg CH4 y(-1)), and a very weak source of nitrous oxide (N2O; similar to 0.00002 Pg N2O-N y(-1)). Anthropogenic disturbance, primarily agriculture and forestry drainage (10%-20% of global peatlands), results in net CO2 emissions, reduced CH4 emissions, and increased N2O emissions. This likely changes the global peatland greenhouse gas balance to a C source (similar to 0.1 Pg C y(-1)), a 10% smaller CH4 source, and a larger (but still small) N2O source (similar to 0.0004 Pg N2O-N y(-1)). There is no strong evidence that peatlands significantly contributed to 20th century changes in the atmospheric burden of CO2, CH4, or N2O; will this picture change in the 21st century? A review of experimental and observational studies of peatland dynamics indicates that the main global change impacts on peatlands that may have significant climate impacts are (1) drainage, especially in the tropics; (2) widespread permafrost thaw; and (3) increased fire intensity and frequency as a result of drier climatic conditions and (or) drainage. Quantitative estimates of global change impacts are limited by the sparse field data (particularly in the tropics), the large variability present in existing data, uncertainties in the future trajectory of peatland use, interactive effects of individual impacts, and the unprecedented rates of climate change expected in the 21st century.

AB Results from an agency-wide survey of U.S. Forest Service personnel indicate that respondents in our sample engage in National Environmental Policy Act (NEPA) public involvement processes primarily to accomplish two goals. The most commonly supported goal was to inform and disclose as mandated by the act. The other goal reflected interests in managing agency relationships with various, often adversarial, publics. Respondents expressed variable views about how to conduct public involvement. Most favored informal meetings and/or formal agency-endorsed strategies, though some respondents favored strategies associated with avoiding or containing the public. Qualitative results suggest that variable views concerning how to go about public involvement are related to individual views of planning in general, the public, and administrative structures and processes. The study raises the question of which factors-the beliefs of those conducting public involvement, or the strategies of public involvement employed-most powerfully impact the outcomes of public involvement processes.

ID FLAX; FIBER
AB Bethune seed flax was collected from Canada with seed removed using a stripper header and straw pulled and left in field for several weeks. Unretted straw was decorticated providing a coarse fiber bundle feedstock for enzyme treatments. Enzyme treatments using a bacterial pectinolytic enzyme with lyase activity were conducted in lab-scale reactors. Four fiber specimens were created: no retting, minimal retting, moderate retting, and full retting. Fiber characterization tests: strength, elongation, diameter, metal content, wax content, and pH were conducted with significant differences between fibers. Thermosetting vinyl ester resin was used to produce composite panels via vacuum-assisted infusion. Composite performance was evaluated using fiber bundle pull-out, tensile, impact, and interlaminar shear tests. Composite tests indicate that composite panels are largely unchanged among fiber samples. Variation in composite performance might not be realized due to poor interfacial bonding being of larger impact than the more subtle changes incurred by the enzyme treatment.

AB Phytoplasmas are cell wall-less bacteria that cause numerous diseases in diverse crops worldwide. Phytoplasma-infected plants often exhibit symptoms suggestive of hormone disorders. Indole-3-acetic acid (IAA), a naturally-occurring auxin, is involved in multiple essential plant growth and developmental processes. It has been shown that exogenous application of IAA can effectively remit symptoms caused by phytoplasma infections. The present study was designed to learn whether exogenously applied IAA would modify phytoplasma-induced changes in host gene expression profiles at the protein level and to understand the role of IAA in phytoplasma pathogenesis.

AB A phytoplasma strain belonging to group 16SrI, subgroup B ('Candidatus Phytoplasma asteris'), the most widely spread phytoplasma worldwide, was detected in diseased larch (Larix sp.) in Ukraine. Detection, identification, and classification of the larch infecting phytoplasma were accomplished through RFLP and sequence analysis of 16S rRNA and ribosomal protein (rp) gene sequences amplified in polymerase chain reactions. The larch infecting phytoplasma was named larch dwarfed needle proliferation (LDNP) phytoplasma. The findings revealed Larix as a previously unknown host of phytoplasma and indicated that 'Ca. P. asteris' is capable of infecting a gymnosperm, while raising questions concerning the identity of possible insect vector(s) involved in transmission of 'Ca. P. asteris' to larch and perhaps to other gymnosperms.

DE RFLP; SNP; differentiation; phytoplasmas; secY gene
AB The number of newly discovered phytoplasma strains has increased dramatically in the last decade. For epidemiological studies and for international quarantine, appropriate molecular tools are essential to identify and distinguish phytoplasmas at taxonomic ranks at and below ribosomal group level. Currently, use of RFLP analysis of the secY gene is one of the finest tools available to achieve the resolving power needed for fine differentiation of closely related phytoplasmas. In the present study, we developed a sytem for computer-simulated SNP-based analysis of secY sequences that incorporates SNPs located both within and outside of restriction sites, increasing the number of characters beyond those used in RFLP analyses. With the inclusion of the additional informative characters, the SNP-based system further enhances strain separation and characterization. This new system will provide additional molecular markers and should aid identification and characterization of strains that are ecologically distinct and/or originate from different geographical regions.

Based on results from restriction fragment length polymorphism profiling and nucleotide sequence alignments of 16S rRNA, tuf, hlyC, trxA-truB, cbiQ-glyA, and rplS-csdB genes, 'bois noir' phytoplasma strains were grouped in five SNP lineages. The data suggest that strain composition of BN phytoplasma populations may be modified by ecological relationships in vineyards.

AB Potato purple top (PPT) is an emerging potato disease complex. The etiological agents of PPT are phloem-inhabiting, cell wall-less bacteria known as phytoplasmas. Tomato is an alternative host of these phytoplasmas. PPT phytoplasma-infected tomato plants exhibit symptoms including abnormal foliage development and formation of "big buds". In the present study, two-dimensional gel electrophoresis (2-DE) was performed to compare the proteomes of healthy and Columbia Basin PPT phytoplasma-infected 'Rutgers' tomato. Our results showed that the levels of at least 15 host proteins were significantly altered in response to PPT phytoplasma infection. The identities of these PPT-responsive proteins and their roles in phytoplasma pathogenesis are currently being examined.

AB The distribution of sagebrush (Artemisia spp.) within the Sage-Grouse Conservation Area (SGCA, the historical distribution of sage-grouse buffered by 50 km) stretches from British Columbia and Saskatchewan in the north, to northern Arizona and New Mexico in the south, and from the eastern slopes of the Sierra Nevada and Cascade mountains to western South Dakota. The dominant sagebrush (sub) species as well as the composition and proportion of shrubs, grasses, and forbs varies across different ecological sites as a function of precipitation, temperature, soils, topographic position, elevation, and disturbance history. Most important to Greater Sage-Grouse (Centrocercus urophasianus) are three subspecies of big sagebrush (Artemisia tridentata)(basin big sagebrush [A. t. ssp. tridentata], Wyoming big sagebrush [A. t. ssp. wyomingensis], and mountain big sagebrush [A. t. ssp. vaseyana]); two low or dwarf forms (little sagebrush [A. arbuscula] and black sagebrush [A. nova]); and silver sagebrush (A. cana), which occurs primarily in the northeast portion of the sage-grouse range. Invasive plant species, wildfires, and weather and climate change are major influences on sagebrush habitats and present significant challenges to their long-term conservation. Each factor is spatially pervasive across the Greater Sage-Grouse Conservation Area and has significant potential to influence processes within sagebrush communities. Cheatgrass (Bromus tectorum), the most widespread exotic annual grass, has invaded much of the lower-elevation, more xeric sagebrush landscapes across the western portion of the Greater Sage-Grouse Conservation Area. A large proportion of existing sagebrush communities are at moderate to high risk of invasion by cheatgrass. Juniper (Juniperus spp.) and pinyon (Pinus spp.) woodlands have expanded into sagebrush habitats at higher elevations creating an elevational squeeze on the sagebrush ecosystem from both extremes. Number of fires and total area burned have increased since 1980 throughout the SGCA except in the Snake River Plain, which has a long-term history of high fire disturbance. Climate change scenarios for the sagebrush region predict increasing trends in temperature, atmospheric carbon dioxide, and frequency of severe weather events that favor cheatgrass expansion and in creased fire disturbance resulting in a decline in sagebrush. Approximately 12% of the current distribution of sagebrush is predicted to be replaced by expansion of other woody vegetation for each 1 degrees C increase in temperature. Periodic drought regularly influences sagebrush ecosystems; drought duration and severity have increased throughout the 20th century in much of the interior western United States. Synergistic feedbacks among invasive plant species, fire, and climate change, coupled with current trajectories of habitat changes and rates of disturbance (natural and humancaused), will continue to change sagebrush communities and create challenges for future conservation and management.

AB Land use in sagebrush (Artemisia spp.) landscapes influences all sage-grouse (Centrocercus spp.) populations in western North America. Croplands and the network of irrigation canals cover 230,000 km(2) and indirectly influence up to 77% of the Sage-Grouse Conservation Area and 73% of sagebrush land cover by subsidizing synanthropic predators on sage-grouse. Urbanization and the demands of human population growth have created an extensive network of connecting infrastructure that is expanding its influence on sagebrush landscapes. Over 2,500 km(2) are now covered by interstate highways and paved roads; when secondary roads are included, 15% of the Sage-Grouse Conservation Area and 5% of existing sagebrush habitats are >2.5 km from roads. Density of secondary roads often exceeds 5 km/km(2), resulting in widespread motorized access for recreation, creating extensive travel corridors for management actions and resource development, subsidizing predators adapted to human presence, and facilitating spread of exotic or invasive plants. Sagebrush lands also are being used for their wilderness and recreation values, including off-highway vehicle use. Approximately 12,000,000 animal use months (AUM = amount of forage to support one livestock unit per month) are permitted for grazing livestock on public lands in the western states. Direct effects of grazing on sage-grouse populations or sagebrush landscapes are not possible to assess from current data. However, management of lands grazed by livestock has influenced sagebrush ecosystems by vegetation treatments to increase forage and reduce sagebrush and other plant species unpalatable to livestock. Fences (>2 km/km(2) in some regions), roads, and water developments to manage livestock movements further modify the landscape. Oil and gas development influences 8% of the sagebrush habitats with the highest intensities occurring in the eastern range of sage-grouse; >20% of the sagebrush distribution is indirectly influenced in the Great Plains, Wyoming Basin, and Colorado Plateau SMZs. Energy development physically removes habitat to construct well pads, roads, power lines, and pipelines; indirect effects include habitat fragmentation, soil disturbance, and facilitation of exotic plant and animal spread. More recent development of alternative energy, such as wind and geothermal, creates infrastructure in new regions of the sage-grouse distribution. Land use will continue to be a dominant stressor on sagebrush systems; its individual and cumulative effects will challenge long-term conservation of sage-grouse populations.

AB Geographic ranges of Greater Sage-Grouse (Centrocercus urophasianus) and Gunnison Sage-Grouse (C. minimus) have contracted across large areas in response to habitat loss and detrimental land uses. However, quantitative analyses of the environmental factors most closely associated with range contraction have been lacking, results of which could be highly relevant to conservation planning. Consequently, we analyzed differences in 22 environmental variables between areas of former range (extirpated range), and areas still occupied by the two species (occupied range). Fifteen of the 22 variables, representing a broad spectrum of biotic, abiotic, and anthropogenic conditions, had mean values that were significantly different between extirpated and occupied ranges. Best discrimination between extirpated and occupied ranges, using discriminant function analysis (DFA), was provided by five of these variables: sagebrush area (Artemisia spp.); elevation; distance to transmission lines; distance to cellular towers; and land ownership. A DFA model containing these five variables correctly classified >80% of sage-grouse historical locations to extirpated and occupied ranges. We used this model to estimate the similarity between areas of occupied range with areas where extirpation has occurred. Areas currently occupied by sage-grouse, but with high similarity to extirpated range, may not support persistent populations. Model estimates showed that areas of highest similarity were concentrated in the smallest, disjunct portions of occupied range and along range peripheries. Large areas in the eastern portion of occupied range also had high similarity with extirpated range. By contrast, areas of lowest similarity with extirpated range were concentrated in the largest, most contiguous portions of occupied range that dominate Oregon, Idaho, Nevada, and western Wyoming. Our results have direct relevance to conservation planning. We describe how results can be used to identify strongholds and spatial priorities for effective landscape management of sage-grouse.

populations; restoration; sagebrush
AB Recent analyses of Greater Sage-Grouse (Centrocercus urophasianus) populations indicate substantial declines in many areas but relatively stable populations in other portions of the species' range. Sagebrush (Artemisia spp.) habitats necessary to support sage-grouse are being burned by large wildfires, invaded by nonnative plants, and developed for energy resources (gas, oil, and wind). Management on public lands, which contain 70% of sagebrush habitats, has changed over the last 30 years from large sagebrush control projects directed at enhancing livestock grazing to a greater emphasis on projects that often attempt to improve or restore ecological integrity. Nevertheless, the mandate to manage public lands to provide traditional consumptive uses as well as recreation and wilderness values is not likely to change in the near future. Consequently, demand and use of resources contained in sagebrush landscapes plus the associated infrastructure to support increasing human populations in the western United States will continue to challenge efforts to conserve Greater Sage-Grouse. The continued widespread distribution of sage-grouse, albeit at very low densities in some areas, coupled with large areas of important sagebrush habitat that are relatively unaffected by the human footprint, suggest that Greater Sage-Grouse populations may be able to persist into the future. We summarize the status of sage-grouse populations and habitats, provide a synthesis of major threats and challenges to conservation of sage-grouse, and suggest a roadmap to attaining conservation goals.

AB In this paper, the conversion of a PC or laptop-controlled microwave moisture meter to a stand-alone meter hosting its own embedded system is discussed. The moisture meter is based on the free-space transmission measurement technique and uses low-intensity microwaves to measure the attenuation and phase shift of the sample, from which the dielectric properties are calculated. The dielectric properties are then used for instantaneous and nondestructive determination of the moisture content in the grain or seed sample. The previous system consisted of the moisture meter and measurement procedure being controlled via USB interface by an external laptop or PC. Though effective, the system lacked full portability and was susceptible to computer failure and interruptions in communication between the meter and computer. To improve the system, a microcontroller was selected in the design of an embedded system for the moisture meter, making it a stand-alone system. The microcontroller provides a graphical 144 x 32 pixel LCD and 16-button keypad to facilitate user interaction. The embedded system provides the following functionalities: user interface (input/output), event execution, process control, data acquisition and data storage. The integration of the embedded system with the microwave meter provides a portable, robust, and cost-effective solution for microwave moisture sensing.

AB The U.S. hardwood sawmilling industry has experienced significant changes over the past decade. A slowing housing industry, competition from imported products, higher transportation costs, and high stumpage prices have changed the business of manufacturing and marketing hardwood lumber. Also, hardwood lumber buyers are changing their business practices by shortening lead times, requiring a more customized product, and buying smaller lumber quantities to cut costs and increase operational flexibility. A survey of hardwood lumber manufacturers was conducted in the fall of 2009 to assess changes and adaptations within the industry. Among respondents, average hardwood lumber sales decreased by 13.2 percent during the study's focus period from 2004 to 2008. Respondents also identified a change in customer demand with smaller, more frequent orders becoming more common. Moreover, the species mix shifted, with red oak losing considerable market share. Intermediaries, such as hardwood lumber distributors, were able to capture more of the industry's business. Respondents identified the slowing housing market and high energy costs as major factors affecting their businesses. While the survey's responses reflected the extremely challenging economic conditions, industry participants are aggressively adapting their businesses and pursuing new opportunities with the understanding that markets will eventually recover.

AB Lignocellulosic feedstocks are often prepared for ethanol fermentation by treatment with a dilute mineral acid catalyst that hydrolyzes the hemicellulose and possibly cellulose into soluble carbohydrates. The acid-catalyzed reaction scheme is sequential, whereby the released monosaccharides are further degraded to furans and other chemicals that are inhibitory to the subsequent fermentation step. This work tests the use of agricultural residues (e. g., plant waste) as starting materials for making activated biochars to adsorb these degradation products. Results show that both furfural and hydroxymethylfurfural (HMF) are adsorbed by phosphoric acid-activated and steam-activated biochars prepared from residues collected from cotton and linen production. Best results were obtained with steam-activated biochars. The activated biochars adsorbed about 14% (by weight) of the furfurals at an equilibrium concentration of 0.5 g/L, and by adding 2.5% of char to a sugar solution, with either furfural or HMF (at 1 g/L), 99% of the furans were removed.

AB We examined the scale-dependent relationship between spatial fire likelihood or burn probability (BP) and some key environmental controls in the southern Sierra Nevada, California, USA. Continuous BP estimates were generated using a fire simulation model. The correspondence between BP (dependent variable) and elevation, ignition density, fuels and aspect was evaluated at incrementally increasing spatial scales to assess the importance of these explanatory variables in explaining BP. Results indicate the statistical relationship between BP and explanatory variables fluctuates across spatial scales, as does the influence of explanatory variables. However, because of high covariance among these variables, it was necessary to control for their shared contribution in order to extract their 'unique' contribution to BP. At the finest scale, fuels and elevation exerted the most influence on BP, whereas at broader scales, fuels and aspect were most influential. Results also showed that the influence of some variables tended to mask the true effect of seemingly less important variables. For example, the relationship between ignition density and BP was negative until we controlled for elevation, which led to a more meaningful relationship where BP increased with ignition density. This study demonstrates the value of a multi-scale approach for identifying and characterising mechanistic controls on BP that can often be blurred by strong but correlative relationships.

AB The frequent fires typical of the longleaf pine ecosystem in the south-eastern USA are carried by live understorey vegetation and pine litter. Mature longleaf pine stands in the xeric sandhills region have a variable understorey vegetation layer, creating several fuel complexes at the within-stand scale (20 m(2)). We identified three fuel complexes found in frequently burned stands on the Carolina Sandhills National Wildlife Refuge, and used prescribed fire to test whether distinct sets of fire conditions were associated with each fuel complex. Study plots were dominated by either turkey oak or wiregrass in the understorey, or lacked understorey vegetation and contained only longleaf pine litter. Turkey oak-dominated plots had the highest fuel loads, and during burns they had higher total net heat flux than wiregrass- or longleaf pine litter-dominated plots, and longer burn durations than wiregrass-dominated plots. Across all plots, the quantity of litter fragments had the greatest effect on fire temperature and duration of burn. These results show that the patchy understorey vegetation within longleaf pine stands will create heterogeneous fires, and areas dominated by turkey oak may have increased fire intensity and soil heating compared with the other two fuel complexes.

AB We investigated the association of inbreeding and infection by the introduced disease white pine blister rust (caused by the fungus Cronartium ribicola J. C. Fisch) with genetic diversity of whitebark pine (Pinus albicaulis Engelm.) by genetically comparing cohorts of different ages in natural stands. Isozyme analysis of bud tissue was used to estimate expected and observed heterozygosity (H(e) and H(o)), and Wright's fixation index (F(is)) for three age cohorts (seedling, young, and mature), sampled from 14 sites in British Columbia, Oregon, Idaho, and Montana. Comparison of genetic diversity parameters among cohorts within a site was used to assess the extent and persistence of inbreeding with age, while comparisons of parameters among sites within a cohort were used to assess the impact of the disease on genetic diversity. Significant evidence of inbreeding (F(is) > 0) was found in all age cohorts. When sites were stratified by level of blister rust infection, differences in F(is) and H(o) among cohorts were only significant when level of infection was low. A significant negative association was found between level of blister rust infection and H(o) in the mature cohort. This suggests that when differential selection due to blister rust is weak, more heterozygous individuals may be favored; however, more homozygous individuals may have higher fitness under higher blister rust levels

AB A Custom made NIR spectroscope was used to determine the moisture content of in-shell peanuts of two different market type peanuts namely Virginia and Valencia. Peanuts were conditioned to different moisture levels between 6 and 26 % (wet basis). Samples from the different moisture levels were separated into two groups one for calibration and the other for validation. NIR absorption spectral data from 1000 nm to 2500 nm were collected on the peanuts from the calibration and validation groups. Measurements were obtained on 30 replicates within each moisture level. Reference moisture data were developed using standard air-oven method on calibration set samples. Partial Least Square (PLS) analysis was performed on the calibration set with certain pretreatments on the measured data and models were developed using the reference moisture data. The Standard Error of Calibration (SEC) and R-2 of the calibration models were computed to select the best calibration model for each of the two peanut types. Both Valencia and Virginia types gave R-2 of 0.99 for the pretreated as well as for the raw spectral data. The selected models were used to predict the moisture content of peanuts in the validation sample set. Predicted moisture contents of the validation samples were compared with their air-oven moisture values determined similarly as for the calibration samples. Goodness of fit was determined based on the lowest Standard Error of Prediction (SEP) and highest R-2 value obtained for the prediction models. The model, with reflectance plus normalization spectral data with an SEP of 0.74 for Valencia and 1.57 for Virginia type in-shell peanuts was selected as the best model. The corresponding R-2 values were 0.98 for both peanut types.

AB The objective of this study was to analyse genetic mutations in the swine odorant binding protein (OBP), map them on the swine genome, and to investigate the association between genetic variants and growth traits. The tissue sample of intramuscular fat from 10 individuals for each growth stage (0, 90, 150, and 210 days) was used to analyse expression levels of OBP gene, resulting in the highest expression levels at day 90. Sequencing analysis of 307 purebred Yorkshire pigs revealed eight single nucleotide polymorphisms, and the sequence was submitted into the GenBank with an accession number (FJ222446). The SNPs at positions 333 and 508 located in an intron region accounted for significant variation of average daily gain. The analysis of radiation hybrid mapping confirmed a location of the swine OBP gene on chromosome 7 between markers S0064 (475.6 cM) and S0025 (497.4 cM) based on the Sus scrofa radiation hybrid and United States Department of Agriculture swine maps. It is concluded that the identified single nucleotide polymorphism may be used as a useful genetic marker associated with average daily gain.

AB There has been little research concerning the association between "place meanings" and "place attachment." An understanding of the association between these constructs is important because they do not stand alone, but rather, complement one another. We documented the meanings ascribed to a national forest in California by five groups of respondents that varied in their mode and attachment intensity to the setting. For example, respondents with high-attachment intensity ascribed meanings related to memories of shared experiences and sense of comfort; whereas the low-attachment respondents were distinguished by the brevity of their narratives. The findings provide a more nuanced understanding of how individuals' level of place attachment is manifested in the way in which they understand and experience the setting.

AB A 126-d feeding trial was performed to investigate graded combinations of distillers dried grains with solubles (DDGS) and soybean meal (SBM) in diets formulated for yellow perch Perca flavescens. Six experimental diets contained DDGS and SBM at 0 and 31.5% (dry matter basis), respectively (0/31.5 diet), 10 and 26% (10/26), 20 and 20.5% (20/20.5), 30 and 15% (30/15), 40 and 9.5% (40/9.5), and 50 and 4% (50/4) to obtain similar levels of crude protein (mean +/- SE = 30.1 +/- 0.2%), crude lipid (16.7 +/- 0.7%), and digestible energy (13.5 +/- 0.2 kJ/g). Fourteen fish (initial individual weight = 19.1 +/- 0.5 g) were randomly selected and stocked into each of twenty-four 110-L tanks (4 replicate tanks/diet). Common biological and mechanical filter systems were used to recirculate the water and maintain similar water quality. Fish that received the 40/9.5 diet exhibited the highest apparent absolute weight gain and percent weight gain, while fish that were fed the 10/26, 20/20.5, 30/15, and 40/9.5 diets exhibited similar absolute weight gain. Fish that were given the 20/20.5, 30/15, and 40/9.5 diets also exhibited similar percent weight gain. Fulton's condition factor and apparent protein digestibility were significantly lower and higher, respectively, for fish that received the 50/4 diet than for all other treatment groups. Crude protein and crude lipid levels in muscle samples did not significantly differ among treatment groups. Results indicated that yellow perch can utilize DDGS plus SBM at a combined inclusion level of up to 49.5% without negative effects on growth. The mechanical strength and color of the extruded pellets were related to the level of DDGS plus SBM in the feed blends. Hepatosomatic indices were correlated with pellet color, while protein digestibility decreased with increasing pellet strength.

TI Use of Fish Hydrolysates and Fish Meal Byproducts of the Alaskan Fishing
Industry in Diets for Pacific White Shrimp Litopenaeus vannamei
SO NORTH AMERICAN JOURNAL OF AQUACULTURE

DT Article
ID AQUACULTURE; PROTEIN; SILAGE; BOONE
AB We determined the suitability of four fish hydrolysates and two fish meals (Pacific halibut Hippoglossus stenolepus and arrowtooth flounder Atheresthes stomias; all derived from byproducts of the Alaskan fishing industry) as replacements for menhaden fish meal in shrimp diets. A control diet (30% crude protein; 8.5% crude lipid) was produced with menhaden meal (13% of diet). Experimental diets were manufactured by using each hydrolysate or fish meal to replace 50% of the menhaden meal on an isonitrogenous basis. Each diet was fed to Pacific white shrimp Litopenaeus vannamei in an outdoor, zero-water-exchange system for 8 weeks. Final weight, survival, feed efficiency, and growth rate were compared among treatments by analysis of variance. The final weights and growth of Pacific white shrimp fed two of the hydrolysates (one acidified to pH 3.8 and left in a liquid state; the other acidified, then neutralized to pH 6.5 and drum-dried) and the two fish meals were not different from those of shrimp fed the control diet. Shrimp that were given the other two hydrolysates (one acidified to pH 3.8 and then drum-dried; the other hydrolyzed [but not acidified] and then drum-dried) had lower final weights and growth than shrimp fed the control diet. These data indicate that the two fish meals and two of the hydrolysates in this trial can replace 50% of menhaden meal in diets for shrimp, although there is some loss of growth potential in some cases. The lack of a diet effect on feed efficiency indicates that the growth differences were mostly the result of differences in feed intake rather than nutritional quality.

AB The effect of daily minimum dissolved oxygen (DO) concentration on the growth and yield of channel catfish Ictalurus punctatus and channel catfish hybrids (female channel catfish x male blue catfish I. furcatus) sharing the Jubilee strain of channel catfish as the maternal parent was evaluated in a 234-d study in sixteen 0.1-ha earthen ponds (15,113 fish/ha). Ponds were managed to maintain a minimum DO concentration of 25% or 50% of saturation. The total consumption of 32%-protein feed at the high and low DO concentrations was 12,973 and 10,262 kg/ha, respectively, for channel catfish and 12,805 and 11,592 kg/ha, respectively, for hybrid catfish. The net yield of hybrid catfish (8,069 kg/ha) did not differ from that of channel catfish (8,037 kg/ha), but the mean individual weight of hybrid catfish was significantly greater. Net yield (8,740 kg/ha), individual weight (0.75 kg/fish), and feed consumption (12,889 kg/ha) were higher for fish in the high DO than in the low DO concentration treatment (7,366 kg/ha, 0.65 kg/fish, and 10,927 kg/ha, respectively). Net yield, individual weight, and feed consumption for channel catfish were 22, 23, and 21% lower, respectively, for the low-DO treatment than for the high-DO treatment, whereas the respective differences for the hybrid catfish were 10, 4, and 10%. Growth did not differ between fish genetic groups but was faster in the high-DO treatment. Channel catfish grew faster in the high-DO treatment, whereas the growth of hybrid catfish did not differ with respect to DO concentration.

AB Two trials were conducted to evaluate two gram-negative bacterial control strategies in batch cultures of the rotifer Brachionus plicatilis. In the first trial, rotifers at an initial density of 47/mL were cultured for 5 d and dosed with a 10-mg/L solution of either oxytetracycline or a commercial probiotic consisting principally of Bacillus and Lactobacillus. In the second trial, rotifers at an initial density of 140/mL were cultured for 4 d and dosed with 20-mg/L solutions of oxytetracycline or the probiotic. Rotifer density, egg counts, and egg : female ratios were determined daily. At the termination of trial 1 and on days 0, 2, and 4 of trial 2, counts of bacterial colonies were conducted to estimate bacterial loads in the rotifer culture water. Oxytetracycline was an effective antimicrobial and enhanced rotifer production in the higher-density culture but had only a marginal effect on production in the lower-density culture. Conversely, inoculation of the low-density culture with the probiotic had no effect on rotifer production. Inoculation of the high-density culture adversely affected rotifer production by increasing mortality and reproductive inhibition.

AB The following study was conducted in order to compare the modified single-seed descent method of selection used in soybean breeding at the Institute of Field and Vegetable Crops in Novi Sad, Serbia, with the standard bulk method and the pedigree method. The source materials for the development of hybrid populations were 15 genotypes, and a total of 10 cross combinations were made. Comparison of the lines developed by the different breeding methods was done in the F6 generation. Genetic gain from selection was taken as the main indicator of efficiency of the tested methods. The modified single-seed descent method produced the best results. In most cases, the mean values for seed yield of the populations developed by that method were significantly higher than the values shown in the populations developed by the other 2 methods. The advantages of using genetic gain as the indicator of breeding efficiency were clearly demonstrated when interpreting the results for seed yield and yield components. Populations possessing desirable traits were easier to perceive, which is exceedingly useful when breeding for a complex trait such as yield.

AB The Run1 locus for dominant resistance to powdery mildew (Erysiphe necator) has been successfully introgressed into Euvitis from Vitis rotundifolia. In the current study, Run1 vines were hybridized with breeding lines at Cornell University, and the presence of the locus was assayed using the markers GLP1-12 and VMC8g9. Signs of powdery mildew were observed on 14 of 113 Run1-positive seedlings in October 2010 in Geneva, N.Y. Severity of infection was lower for Run1-positive than for Run1-negative seedlings. Presence of mature cleistothecia suggested infection by at least two pathogen genotypes, which since V rotundifolia is not grown within 800+ km of Geneva, N.Y., evolved from a pathogen population naive to Run1 resistance. Therefore, caution in the deployment of the Run1 locus in new resistant cultivars is suggested so the effectiveness of Run1 does not diminish over time.

AB There is a strong economic interest in routine measurements of cotton quality as production processes and final products depend on it. An important cotton property is "micronaire," a parameter that is indicative of the fibers' maturity and its fineness. Currently, micronaire is normally measured in laboratories with equipment that prohibits routine field analyses. The goal of this study is a proof-of-principle demonstrating that cotton quality as determined via fiber micronaire is correlated to fiber properties and that these properties can be determined by near-infrared (NIR) reflection spectroscopy using portable instrumentation in conjunction with Principal Component Regression for micronaire prediction. A set of 191 cotton samples was acquired from over 100 different upland cotton varieties, and initial spectroscopic studies confirmed the feasibility of NIR spectroscopy to measure cotton micronaire in the laboratory with portable NIR instrumentation. Sample reproducibility was an issue which has been resolved with two approaches, that is, model spectral artifacts, mainly baseline shifts, by means of chemometric calibrations or application of second derivative spectroscopy to suppress baseline drifts. Results from this study demonstrated in up to 90% of the test samples that the micronaire values fall into the acceptance range. Thus, a promising new approach for field analyses is on the horizon and has been assessed in this study. Further, the acceptance range could be reduced to +/- 0.2 m.u. and still >= 70% of the samples fell inside the restricted acceptance range. Up to 60% of the samples fell inside an acceptance range of +/- 0.1 m.u.

AB Shifts in vegetation composition and cover are the result of processes acting at different levels such as landscapes, hill slopes, or plant interspaces. Analytical approaches designed for discrete objects which are based upon the inherently hierarchical nature of complex systems are well suited to research applications conducted across spatial scales. We quantified spatial and temporal vegetation dynamics over 71 years at three spatial scales, landscape, plot, and patch, in a Chihuahuan Desert ecosystem in southern New Mexico, USA, using object-based analysis. We analyzed time series aerial photography from 1937 to 2008 to include automated image analysis at the landscape scale and manual delineation of shrub image objects at the patch scale. We sought to identify patch mechanisms associated with changes in shrub patch density and percent cover by characterizing structural changes in individual shrub patches from one image to the next in the time series. The classification scheme captured colonization by new shrub patches, growth or decline in patch area, and patch stability (i.e., change in size of less than 15%). Patch growth was categorized as growth by coalescence with neighboring patches or canopy expansion. Similarly, patch decline was distinguished as either loss of patch area due to canopy dieback or fragmentation of conglomerate patches. Interpretations of change in patch density based solely on shrub colonization and mortality can be too simplistic. Increases in patch density can result from an influx of new patches or fragmentation of patches into its constituent patches; conversely, decreases in density may be due to mortality of patches or coalescence of existing patches. We demonstrate that patches grew in size at the beginning of the study in conjunction with increases in shrub cover (0.5% in 1937 to 11% in 1960) and patch density increased during the initial encroachment phase of shrub proliferation (4 patches ha(-1) in 1937 to 80 patches ha(-1) in 1960). Shrub cover remained stable at 7% from 1967 to 1989 and over this period, patch dynamics were broadly characterized by growth and persistence of patch area with roughly equal proportions of mortality and colonization. Shrub cover increased linearly from 8% in 1989 to 14% in 2008, approaching a projected maximum shrub cover of 18% based on mean annual precipitation (MAP) of 230 mm. Patch fate over this period constituted growth and persistence of shrub patch area whereas appearance of new patches remained relatively stable. Shrub patch dynamics were non-linear and variable over time. We documented the transition from grass-to shrub-dominated states with patch dynamics signifying a shifting mosaic in which shrub patch establishment, growth, and mortality wax and wane. Monitoring patch dynamics will become increasingly important in actively managed ecosystems as an important indicator of impending shifts in ecosystem structure and function.

AB This study examined U.S. demand for salmon imports differentiated by source (Canada, Chile, and the rest of the world [ROW]), product cut (fillets and other salmon products), and form (fresh and frozen). The Rotterdam model was used in estimation, and source-aggregation tests were performed to determine the significance of source differentiation in analysis. We also performed separability tests to determine if import preferences were source-wise dependent or source independent. Test results strongly reject source aggregation; however, source-wise dependence could not be rejected. Furthermore, source-aggregated demand was significantly more price-elastic when compared to source-wise dependent demand. Results show that import preferences are not homogeneous across exporting countries, and there is significant information loss when source differentiation is not considered.

AB Nyssa trees involved in a breeding program for ornamentals were found to be affected deleteriously by a leaf spot disease. The causative agent was identified as a species of Mycosphaerella that had been classified as morphologically indistinguishable from M. punctiformis. A subsequent taxonomic investigation using morphological data from new and existing herbarium collections, cultural data, and ITS region rDNA sequences suggested that this was a distinct species on Nyssa that represents the previously described M. nyssicola. The species is lectotypified and epitypified to promote nomenclatural and taxonomic stability.

AB Thin films of hafnium oxide (HfO2) were deposited by atomic layer deposition (ALD). The structural properties of the deposited films were characterised by transmission electron microscopy (TEM) and X-ray diffraction (XRD). We investigated the effect of phase transformations induced by thermal treatments on the mechanical properties of ALD HfO2 using nanoindentation. The elastic modulus of the amorphous low temperature deposited ALD HfO2 films was measured to be 370 +/- 20 GPa. Subsequent to crystallisation by annealing in a rapid thermal annealing (RTA) chamber, the elastic modulus dropped to 240 +/- 20 GPa. Similarly, the Meyer hardness decreased from a value of 18 +/- 1 GPa for amorphous HfO2 to 15 +/- 1 GPa following the transition temperature from amorphous to polycrystalline HfO2.

AB The presence of Listeria monocyto genes on the surfaces of equipment and worker's hands during different production stages, as well as on fish skin and meat during processing and storage of cold-smoked trout, was investigated. Listeria monocyto genes was recovered from 10 (6.06%) of a total 165 cotton-swabbed samples collected from the surfaces of equipment and worker's hands at two separate processing facilities. Of 105 samples collected from fish skin and meat during various production steps in both processing plants, 14 (13.33%) were confirmed culture-positive for L. monocyto genes, with recovery being most frequently in samples collected in the area before vacuum packaging. Recovery rates at two different Serbian processing plants did not differ (p<0.05), but suggested that different L. monocyto genes serotypes appeared to be resident within each processing plant and may have contributed to the final product contamination. From all smoked trout samples collected during 7, 14, 21 and 28 days of storage at 4 degrees C only two were culture-positive for L. monocyto genes serotype 1/2a and both of these were collected on the 7(th) day of storage. Conversely, 4, 3 and 1 sample(s) were contaminated with L. monocyto genes serotypes 1/2a and 1/2b after 7, 14 and 21 days storage at 10 degrees C. Listeria monocyto genes was not recovered from smoked trout stored 28 days at 10 degrees C. Results emphasize the importance of adhering to strict hygienic and quality control standards throughout the processing environment.

AB Natural fibers for many and varied industrial uses are a current area of intense interest. Production of these fibers, furthermore, can add to farmer incomes and promote agricultural sustainability. Flax (Linum usitatissimum L.), which has been used for thousands of years, is unparalleled in supplying natural fibers for industrial applications as diverse as textiles and paper, providing high value linseed and fiber from a single plant, and maintaining sustainable agriculture in temperate and subtropical climates for summer or winter production, respectively. As a value-added replacement for glass fiber from a renewable resource, flax fiber is recyclable, biodegradable, and sustainable for the economy, ecology, and society. To the point, Daintier Chrysler reported that natural fibers for automotive components required 83% less energy and were 40% less expensive than glass fiber components. A better understanding of the fiber characteristics that influence composite performance could lead to the development of additives, coatings, binders, or sizing suitable for natural fiber and a variety of polymeric matrices. Stems of flax require retting to separate fiber from nonfiber components and rigorous mechanical cleaning to obtain industrial-grade fibers. Considerable work has been undertaken to improve the retting process using specific cell-free enzymes, especially pectinases, to control and tailor properties for industrial applications. Fiber processing and use in composites are affected by variables such as length, uniformity, strength, toughness, fineness, surface constituents, surface characteristics, and contaminants. One of the main concerns for the composite and other industries in incorporating natural fibers, such as flax, into production parts is the fiber variability resulting from crop diversity, retting quality, and different processing techniques. Standardized methods to assess flax fiber properties, therefore, are needed to maintain quality from crop to crop and provide a means to grade fibers for processing efficiency and applications. Other parts of the plant stalk, notably the waste shive and dust, can potentially be utilized as coproducts to offset costs for producing the major products of fiber and seed.

AB Theobroma cacao (cacao) is a tropical understory tree with sensitivity to drought. Cacao responds to drought by decreases in net photosynthesis, PS II efficiency, stomatal conductance, water potential and changes in leaf florescence. Drought also alters cacao gene expression as well as leaf glucose and free amino acid content. In recent years an incredible diversity of fungal endophytes has been identified in association with cacao. These endophytes are being studied for the benefits they provide to cacao including tolerance to biotic and abiotic stresses. During establishment of the endophytic association between cacao and fungal endophytes both plant and fungal gene expression are altered. The endophytic Trichoderma hamatum isolate DIS 219b delays the onset of drought stress in cacao. This delay manifests itself through enhanced root growth, maintenance of stomata] conductance, water potential, net photosynthesis, and PSII efficiency, changes in free amino acid concentrations, and a delay in drought-induced changes in leaf gene expression. The cacao plant and DIS 219b adapt to each other and this adaptation may contribute to the observed plant growth promotion and the delay in onset of drought stress. The increase in root growth is thought to increase water uptake and availability, delaying the time point where the water supply becomes limiting and drought stress occurs.

AB There is a rising concern among natural resource scientists and managers about decline of the many plant and animal species associated with early successional habitats. There is no concise definition of early successional habitats. However, all have a well developed ground cover or shrub and young tree component, lack a closed, mature tree canopy, and are created or maintained by intense or recurring disturbances. Most ecologists and environmentalists agree that disturbances and early successional habitats are important to maintain the diverse flora and fauna native to deciduous eastern forests. Indeed, many species, including several listed as endangered, threatened, sensitive, or of management concern, require the openness and thick cover that early successional habitats can provide. Management of early successional habitats can be based on the "historic natural range of variation", or can involve active forest management based on goals. In this book, expert scientists and experienced land managers synthesize knowledge and original scientific work to address critical questions on many topics related to early successional habitats in the Central Hardwood Region. Our aim is to collate information about early successional habitats, to aid researchers and resource management professionals in their quest to sustain wildlife and plant species that depend on or utilize these habitats.

AB Oaks and hickories characterize the Central Hardwood Region, with its temperate, humid climate and deep soils. Several xerophytic species characterize stands on xeric sites; mesic sites usually have greater diversity of oaks and hickories and include maple, ash, beech, and yellow-poplar. Ice and wind storms are common disturbances across the region; wildland fires ignited by lightning are uncommon and generally confined to small, stand-size areas. Variable environmental conditions, topography, and forest species compositions from the eastern Appalachians to the western Ozarks can require different silvicultural prescriptions to create early successional habitats, even in stands of similar appearance.

AB Fire helped shape the structure and species composition of hardwood forests of the eastern United States over the past 14,000 years. Periodic fires were common in much of this area prior to European settlement, and fire-resilient species proliferated. Early European settlers commonly adopted Native American techniques of applying fire to the landscape. As the demand for wood products increased, large cutover areas were burned, sometimes leading to catastrophic fires and subsequent early successional habitats. By the early 1900s, these catastrophic fires resulted in political pressure leading to policies that severely restricted the use of fire. Fire suppression continued through the twentieth century due to an emphasis on commodity production and under-appreciation of the ecological role of fire. Without fire, fire-sensitive species were able to successfully outcompete fire-adapted species such as oak and pine while early successional habitats matured into older and more homogeneous forests. In the late twentieth century, land managers began reintroducing fire for ecosystem restoration, wildlife habitat improvement, hazardous fuel reduction, and forest regeneration. Responsible expanded use of prescribed fire and other management tools in the region could help mitigate past actions by increasing the amount and distribution of early successional habitats, plant and animal diversity, and landscape heterogeneity.

AB Early successional habitats can be created with a broad array of silvicultural techniques that remove all or most canopy trees in one to several cuttings and small to large patch sizes. Composition and early structural development of the resulting vegetation can be variable. Arborescent species composition is a function of regeneration sources already present and those that arrive during or after the cutting. The suite of species available for regeneration of a site, large or small, is a cumulative effect of disturbances and varies across multiple environmental gradients that include moisture, elevation (temperature), and soil chemistry.

ID MANAGEMENT
AB Forest inventory data provide simple indicators of forest structural diversity in the form of forest age distributions and their change over time. A result of past land use and disturbance, more than half of the 51 million ha of forest in the Central Hardwood Region is between 40 and 80 years old and young forest up to 10 years old constitutes only 5.5% of the area. Simulations of a sustained level of management over time produce more uniform (flatter) age-class distributions. A management scenario designed to maintain about 7% of total forest area as young habitat results in a region-wide young forest deficit of one million ha relative to current conditions. However, management activities that create an average of 200 ha of additional young forest per county per year would be sufficient to erase that deficit.

AB The herbaceous layer varies with topographic heterogeneity and harbors the great majority of plant diversity in eastern deciduous forests. We described the interplay between disturbances, both natural and human-caused, and composition, dynamics, and diversity of herbaceous vegetation, especially those in early successional habitats. Management actions that create low to moderate disturbance intensity can promote early successional species and increase diversity and abundance in the herb layer, although sustaining communities such as open areas, savannahs, and woodlands may require intensive management to control invasive species or implement key disturbance types. A mixture of silvicultural practices along a gradient of disturbance intensity will maintain a range of stand structures and herbaceous diversity throughout the central hardwood forest.

AB Young (1-10 year post-disturbance) upland hardwood forests function as high-quality food patches by providing abundant fruit, and nutritious foliage and flowers that attract pollinating and foliar arthropods and support high populations of small mammals that, in turn, are prey for numerous vertebrate predators. Reductions in basal area increase light penetration to the forest floor, which stimulates vegetative growth and promotes fruiting. Fruit biomass (dry edible pulp) can be 5 to nearly 50 times greater in young forest than mature forest as "pioneer" species, such as pokeweed and blackberry, ericaceous shrubs, various forbs and grasses, and stump sprouts of many tree species produce fruit. Forage production can increase substantially after disturbances that significantly reduce overstory basal area, such as timber harvests, heavy thinning, or intense prescribed fire. Hard mast (nut) production can be sustained in young forests if some mature, good mast-producing oak, hickory, or beech trees are retained. Balancing the creation of young, recently disturbed upland hardwood forests with the desired amount and distribution of other forest age-classes will sustain high-quality food patches for wildlife within a landscape context.

AB Early successional habitats are an important part of the forest landscape for supporting avian communities. As the frequency and extent of the anthropogenic disturbances have declined, suitable habitat for scrub-shrub bird species also has decreased, resulting in significant declines for many species. We related changes in the proportion and distribution of small-diameter upland hardwood forest throughout the eastern USA (US Forest Service Forest Inventory and Analysis data) with North American Breeding Bird Survey data (US Geological Survey) on population trends of 11 species that use early successional hardwood forest. The availability of small-diameter upland hardwood forest has changed over the past four decades, with the biggest differences seen as declines from the 1990s to the 2000s. Most scrub-shrub species also declined since the inception of the Breeding Bird Survey in 1966. The declines in most of the bird species, however, did not closely track the changes in small-diameter forest availability. Scrub-shrub birds use a variety of habitats that originate from a diverse array of disturbance sources. The total availability of these habitats across the region apparently limits the populations for these species. A comprehensive management strategy across all of these types is required to conserve these species.

AB Early successional habitats are important foraging and commuting sites for the 14 species of bats that inhabit the Central Hardwood Region, especially larger open-adapted species such as hoary bats (Lasiurus cinereus), red bats (L. borealis), silver-haired bats (Lasionycteris noctivagans), and big brown bats (Eptesicus fuscus). Forest gaps, small openings, and the edges between early successional patches and mature forest are especially important habitats because they are used by both open-adapted and clutter-adapted species. Several bat species select roosts in close proximity to early successional patches, perhaps to minimize foraging and commuting costs. Future research on effects of early successional patch size, shape, vegetation structure, and connectivity on bat use, and the distribution of early successional habitats in relation to mature forest, roosting sites, and water sources will assist managers in providing the optimal types and distribution of early successional patches on the landscape.

AB Herpetofauna responses to forest management and early successional habitats are influenced by species-specific adaptations to historical disturbance regimes. It can take decades for woodland salamander diversity to recover after heavy overstory removal for even-aged forest regeneration or hot fires that yield higher light, drier microclimates, and reduced leaf litter cover, but some frog and toad species may tolerate or even increase after disturbances. In particular, disturbances that retain some canopy cover, such as selection harvests or low intensity burns, can mitigate effects on terrestrial salamanders. The same early successional conditions that are detrimental to salamanders can benefit many reptile species, such as fence lizards (Sceloporus undulatus). Maintaining stand age diversity across central hardwood forest landscapes, including retention of mature forest communities, should provide habitats for both early successional wildlife and mature forest species.

AB Tree harvests that create early successional habitats have direct and indirect impacts on water resources in forests of the Central Hardwood Region. Stream( low increases substantially immediately after timber harvest, but increases decline as leaf area recovers and biomass aggrades. Post-harvest increases in stormflow of 10-20%, generally do not contribute to downstream flooding. Sediment from roads and skid trails can compromise water quality after cutting. With implementation of Best Management Practices (BMPs), timber harvests are unlikely to have detrimental impacts on water resources, but forest conversion from hardwood to pines, or poorly designed road networks may have long lasting impacts. Changing climate suggests the need for close monitoring of BMP effectiveness and the development of new BMPs applicable to more extreme climatic conditions.

AB Across a forested landscape, stand-level management actions or natural disturbances that create early successional habitats result in a short-term loss of carbon in any given stand, but are often offset by carbon gains in other, undisturbed stands. Standing carbon stocks and rates of sequestration vary with species, site productivity, stand age, and stand structure. The age distribution of forest stands has a particularly large effect on landscape-level carbon storage. Consequently, forest management activities, including creation of early successional habitats, have short-term implications for stand-level carbon storage, but their impact on forest- or landscape-level carbon storage ultimately depends upon the temporal distribution and spatial scale of young forest stands on the landscape.

AB This chapter describes how forest type and age distributions might be expected to change in the Appalachian-Cumberland portions of the Central Hardwood Region over the next 50 years. Forecasting forest conditions requires accounting for a number of biophysical and socioeconomic dynamics within an internally consistent modeling framework. We used the US Forest Assessment System (USFAS) to simulate the evolution of forest inventories in the subregion. The types and ages of forests in the Appalachian-Cumberland portions of the Central Hardwood Region are likely to shift over the next 50 years. Two scenarios bracket a range of forest projections and provide insights into how wood products markets as well as economic, demographic, and climate changes could affect these future forests. Shifts in the future age distributions of forests are dominated by projected harvest regimes that lead to qualitatively different forest conditions. The future area of young forests correlates with change in total forest area-as total forest area declines, so does the area of young forests. However, changes in the area of young forests and forest age class distributions are most directly altered by the extent of harvesting within the Appalachian-Cumberland subregion.

TI Keeping Springtime Low-Volume Road Damage to a Minimum Toolkit of
Practical Low-Cost Methods for Road Managers
SO TRANSPORTATION RESEARCH RECORD
LA English
DT Article
AB There are approximately 3 million miles of low-volume roads (LVRs) in the United States, and approximately half of them are located in seasonal frost areas. Limiting or prohibiting loads during spring thaw can keep damage to a minimum. However, methods of determining when to place and remove spring load restrictions, particularly on LVRs, are often highly subjective if restrictions are imposed at all. In partnership with several other agencies, the U.S. Department of Agriculture Forest Service has been compiling a toolkit of practical low-cost diagnostic techniques for determining conditions under which spring load restrictions should be placed and removed. This paper expands on techniques reported in a previous paper from a TRB low-volume roads conference and reports on further developments of additional methods. Techniques discussed include (a) subsurface instrumentation, (b) lightweight deflectometer, (c) thaw index, (d) climatic thaw predictor model, and (e) length of time. Requirements and equipment needed to use each of the techniques are described, strengths and weaknesses of each are outlined, and recommendations on various combinations of methods are provided to enable road managers to optimize placement of spring load restrictions.

AB Cropping systems in the Great Plains are changing because of no-till. Rotations now include a diversity of crops in contrast with rotations in tilled systems that grow only one or two crops. This diversity of crops often leads to yield increases because of the rotation effect. We have observed that crop response to the rotation effect can be categorized as either improving resource-use efficiency or increasing plant size and yield capacity. An example of the efficiency response, which we term synergism, is that some crops improve water-use efficiency (WUE) of following crops. Crops produce more grain with the same water use in synergistic sequences; in contrast, crops that increase yield capacity consume more water to produce more grain. Further, synergism among crops increases tolerance of weed interference because of improved resource-use efficiency. Synergism is more prominent in low-yielding environments due to stresses such as drought, and appears to be rare among crop sequences. The cause of synergism among crops is likely related to a multitude of interacting factors such as microbial changes, growth-promoting substances, and altered nutrient cycling. Quantifying WUE as affected by preceding crop may provide a method to identify synergism among crops. No-till rotations that include synergistic crop sequences are improving land productivity, farm economics, soil health, and resource-use efficiency in the semiarid Great Plains.

AB Insects make up the largest and most diverse group of organisms on earth, contributing to as much as 80-90% of the world's biodiversity. Approximately 950,000 species of insects have been described; some estimate there are 4,000,000+species in total. Over 70% of drugs on the market are derived from natural compounds. However, insects are one of the least explored groups in drug discovery. The world adds about 70 million people each year. In this chapter you will find: (1) an introduction to the topic of arthropod chemical biodiversity and chemical defense; (2) a brief discussion on various uses of insect chemistry by various cultures; (3) an overview of insect venoms and other chemical defense studies, with a case study on methods utilized to analyze ant venoms; (4) a short discussion on the importance of preserving tropical habitats for bioprospecting; (5) a review of research on stick insect (Order Phasmatodea) chemical defenses, stick insects as a model for biosynthesis studies and my personal experiences with the editors of this book and 2008 PAST workshop in Peru which resulted in this chapter; (6) an overview of examples from the literature of insect-derived substances with medicinally relevant biological properties such as toxins and antibiotics; (7) a brief description of the importance of studying biosynthetic pathways in insects and other organisms from whence valuable natural products are identified and (8) a list of recommended literature which I expect would be of particular interest to the readers of this chapter.

AB Moisture diffusivity values of different rice kernel components, namely endosperm, bran and husk, are required to solve mathematical models describing absorption and desorption processes. In addition to the rice variety and temperature, the moisture diffusivity also depends on its instantaneous moisture content or water activity (a(w)) and whether rice is absorbing or desorbing moisture. This research was undertaken to determine moisture diffusivity values of rough rice components in different a(w) ranges during absorption and desorption. Experiments were performed to measure sorption rates of different rice forms, including white rice, brown rice, and rough rice kernels. Mathematical models were developed to predict their moisture distribution during moisture sorption processes. These models were solved by finite element method using Comsol Multiphysics (R) simulation program. Moisture diffusivity values of different rice components were calculated and found to be different during absorption and desorption. Diffusivity of rice endosperm was higher during desorption than absorption at a(w) higher than 0.20 and increased with an increase in a(w) in 0.20-0.80 a(w) range. Diffusivity of bran remained almost the same with a(w) while diffusivity of husk decreased with an increase in a(w). Results obtained in this research demonstrated that the moisture diffusivity of different rice components varies significantly with the change in water activity or moisture and should be accounted in the mathematical models.

AB Papaya is a major fruit crop in the tropics and has recently evolved sex chromosomes. Towards sequencing the papaya sex chromosomes, two bacterial artificial chromosome (BAC) libraries were constructed from papaya male and female genomic DNA. The female BAC library was constructed using restriction enzyme BstY I and consists of 36,864 clones with an average insert size of 104 kb, providing 10.3x genome equivalents. The male BAC library was constructed using restriction enzyme EcoR I and consists of 55,296 clones with an average insert size of 101 kb, providing 15.0x genome equivalents. The male BAC library was used in constructing the physical map of the male-specific region of the male Y chromosome (MSY) and in filling gaps and extending the physical map of the hermaphrodite-specific region of the Y(h) chromosome (HSY) and the X chromosome physical map. The female BAC library was used to extend the X physical map gap. The MSY, HSY, and X physical maps offer a unique opportunity to study chromosomal rearrangements, Y chromosome degeneration, and dosage compensation of the papaya nascent sex chromosomes.

AB Guidelines for water-quality monitoring have traditionally focused on the use of bacterial indicators. However, efforts to effectively mitigate fecal contamination necessitate greater clarity in source recognition. Host (mammalian and avian) epithelial cells are shed in the gut lumen and expelled in feces. These cells have multiple numbers of mitochondria, an organelle with its own genome, containing species-specific DNA sequences. These properties make mitochondrial DNA sequences (mtDNA) excellent molecular targets as they are host-specific and robust. This chapter describes the development of molecular methods such as PCR, qPCR, PCR with consensus primers, and DNA microarrays to detect and quantify mtDNA in effluents, influents, and environmental surface waters. These assays represent a paradigm shift in source tracking by detecting DNA from the host rather than its fecal bacterial population. Future development to increase the sensitivity of the assays and ease sample processing of large volumes is warranted. Contamination by nonfecal sources such as skin, hair, and sputum of swimmers needs to be evaluated in the context of providing data for source tracking, i.e., presence of human activity impacting the site. The significance of meat carryover in human feces, waste from kitchen garbage disposals and abattoir or industrial manufacturing requires further study to assess their impact on species-specific source tracking.

AB Fourier transform infrared (FT-IR) spectra of seed and lint cottons were collected to explore the potential for the discrimination of immature cottons from mature ones and also for the determination of actual cotton maturity. Spectral features of immature and mature cottons revealed large differences in the 1200-900 cm(-1) region, and such spectral distinctions formed the basis on which to develop simple three-band ratio algorithm for classification analysis. Next, an additional formula was created to assess the degree of cotton fiber maturity by converting the three-band ratios into an appropriate FT-IR maturity (M-IR) index. Furthermore, the M-IR index was compared with parameters derived from traditional image analysis (IA) and advanced fiber information system (AFIS) measurements. Results indicated strong correlations (R-2 > 0.89) between M-IR and M-AFIS and between M-IR and M-IA among either International Cotton Calibration (ICC) standards or selected cotton maturity references. On the other hand, low correlations between the pairs were observed among regular cotton fibers, which likely resulted from the heterogeneous distribution of structural, physical, and chemical characteristics in cotton fibers and subsequent different sampling specimens for individual and independent measurement.

TI Stream Simulation for Aquatic Organism Passage at Road-Stream Crossings
SO TRANSPORTATION RESEARCH RECORD
LA English
DT Article
AB Historically, road stream crossing structures were designed on the basis of the hydraulic capacity of the structure for a specific design flood without consideration of aquatic species or the swimming and jumping abilities of a single target fish species and life stage during its migration, and ignored the movement needs of other adult fish, juvenile fish, and aquatic organisms occupying the stream. Hydraulic designs typically constrict the channel, create flow hydraulics and channel conditions that are markedly dissimilar from those in the natural channel, and impede the movement of most other nontarget fish and aquatic organisms along the stream corridor. The stream simulation approach for designing road stream crossing structures was recently adopted by the U.S. Department of Agriculture Forest Service as a pragmatic and sustainable long-term solution to maintain passage for all aquatic organisms at all life stages at road stream crossings while meeting vehicle transportation objectives. This study shows how the stream simulation design process integrates fluvial geo-morphology concepts with engineering principles to design a natural and dynamic channel through the road stream crossing structure. The premise of stream simulation is that the creation of channel dimensions and characteristics similar to those in the adjacent natural channel will enable fish and other aquatic organisms to experience no greater difficulty moving through the structure than if there were no crossing. Stream simulation channels are designed to adjust laterally and vertically to a wide range of floods and sediment or wood inputs without compromising the movement needs of fish and other aquatic organisms or the hydraulic capacity of the structure.

TI Storm Damage Risk Reduction Storm Proofing Low-Volume Roads
SO TRANSPORTATION RESEARCH RECORD
LA English
DT Article
AB The United States and other countries spend millions of dollars annually on storm damage repairs. Most of this work is to repair existing roads and transportation facilities. Large amounts of repair work have been done on the low-volume road network of the U.S. Department of Agriculture Forest Service over the past three decades, particularly in the Pacific Northwest. Agencies cannot afford to build roads to be 100% storm resistant, or stormproof, but they can be made more storm resistant. Measures can be taken to reduce the risk of storm damage from any given event. The objectives of this paper are to identify the assessment process and discuss treatments that can be used to reduce road damage and environmental impacts. Storm damage risk reduction first involves an assessment of any given road, the natural setting, the value of the road, traffic use, and design standards. Because resources are always limited, roads in areas of high risk, in steep terrain, or in areas subject to flooding, and the most important roads, from both the infrastructure and environmental standpoints, should be prioritized for preventative work. Storm damage risk reduction measures include many maintenance, drainage improvement, and structural tasks. Roadway surface drainage structures such as ditches, cross drains, and rolling dips need to be clean, properly armored, and properly spaced to prevent the concentration of water. Drainage-crossing structures such as bridges, fords, and culverts need to have adequate capacity or at least be clear of debris, well armored, scour resistant, and functioning properly. Trash racks can be added. Marginally stable road cuts and fills can be modified and reinforced with vegetation or soil bioengineering treatments. Staying current with road maintenance is critical for proper road function during storms.

AB Biology of Bemisia tabaci on five different host plants viz., cassava, sweet potato, cotton, egg plant and tobacco showed that developmental duration was maximum on cassava and fecundity was maximum on tobacco. Population of cassava whitefly (CWF) and sweet potato whitefly (SPWF) separately maintained on the respective host plants were used in two sets of experiments viz., choice and no-choice studies on cassava, sweet potato, egg plant, cotton, tobacco and tomato. Oviposition was recorded on all host plants, but no CWF nymphs emerged beyond the first instars on sweet potato, while there was no pupal formation or adult development of SPWF on cassava. In choice tests, CWF reproduced on cassava, egg plant, tomato and tobacco, but not on cotton and sweet potato. Conversely, SPWF reproduced on sweet potato, cotton, egg plant, tomato and tobacco, but not on cassava, indicating two different biotypes. In isozymes studies five non-shared alleles to CWF and six to SPWF were observed, ascertaining the biotypes. The analysis of amplification products obtained using the single primers revealed that the CWF and SPWF do not share any similarity among them, confirming the biotypes. Secondary endosymbionts were not associated with the two biotypes.
Role of B. tabaci CWF and SPWF on Indian cassava mosaic virus (ICMV) transmission was elucidated from cassava to cassava and cassava to tobacco, with different number of whiteflies and different acquisition access feeding periods (AAFP) and inoculation access feeding periods (IAFP). Even a single whitefly was capable of ICMV transmission under 10 h/10 h AAFP/IAFP and maximum percentage of transmission was in 48 h/48 h AAFP/IAFP. ICMV transmission in cassava plants through B. tabaci was ascertained using dot-blot immunoassay, TAS-ELISA and Immuno-scanning electron microscopy. ICMV DNA tests in whitely stylet, salivary gland and digestive tract showed positive.
The activity of rhodanese and beta-cyanoalanine synthase; cyanide detoxifying enzymes in B. tabaci reared on cassava and sweet potato gave supportive evidence for different biotypes. Whitefly feeding induced pathogenesis related (PR) proteins in both ICMV-free and ICMV-infected cassava plants. Heavy infestation of B. tabaci showed increased level of PR proteins. Quantitative measurement and electrophoretic detection of total protein, peroxidase, chitinase and beta 1,3 glucanase in both ICMV-infected and ICMV-free cassava plants under whitefly infested and non-infested conditions revealed that cassava plants with whitefly infestation had an increased level of peroxidase, chitinase and beta 1,3 glucanase, and decreased level of total proteins.

AB Remote sensing technology has long been used for detecting insect infestations on agricultural crops. With recent advances in remote sensing sensors and other spatial information technologies such as Global Position Systems (GPS) and Geographic Information Systems (GIS), remote sensing is finding more and more practical applications for the detection and management of insect pests, including sweetpotato whitefly, Bemisia tabaci (Gennadius). This chapter begins with an extended overview of remote sensing principles and systems that can be used for entomological studies. Properties and behavior of electromagnetic energy, major divisions of the electromagnetic spectrum (i.e., ultraviolet, visible, infrared and microwave), and the interactions between radiation and ground targets are discussed. Major types of remote sensing systems are described, including ground-based spectroradiometers, aerial photographic cameras, airborne digital multispectral and hyperspectral imaging systems, and moderate and high resolution satellite imaging systems. The second part of the chapter provides a brief review on the use of remote sensing for detecting whitefly infestations and presents an application example to illustrate how remote sensing can be integrated with GPS and GIS technologies for detecting and mapping whitefly infestations in cotton fields. The methodologies for ground reflectance and airborne image acquisition and for the integration of image data with GPS and GIS are discussed.

AB A more thorough understanding of the multi-scale spatial structure of land surface heterogeneity will enhance understanding of the relationships and feedbacks between land surface conditions, mass and energy exchanges between the surface and the atmosphere, and regional meteorological and climatological conditions. The objectives of this study were to (1) quantify which spatial scales are dominant in determining the evapotranspiration flux between the surface and the atmosphere and (2) to quantify how different spatial scales of atmospheric and surface processes interact for different stages of the phenological cycle. We used the ALEXI/DisALEXI model for three days (DOY 181, 229 and 245) in 2002 over the Ft. Peck Ameriflux site to estimate the latent heat flux from Landsat, MODIS and GOES satellites. We then applied a multiresolution information theory methodology to quantify these interactions across different spatial scales and compared the dynamics across the different sensors and different periods. We note several important results: (1) spatial scaling characteristics vary with day, but are usually consistent for a given sensor, but (2) different sensors give different scalings, and (3) the different sensors exhibit different scaling relationships with driving variables such as fractional vegetation and near surface soil moisture. In addition, we note that while the dominant length scale of the vegetation index remains relatively constant across the dates, the contribution of the vegetation index to the derived latent heat flux varies with time. We also note that length scales determined from MODIS are consistently larger than those determined from Landsat, even at scales that should be detectable by MODIS. This may imply an inability of the MODIS sensor to accurately determine the fine scale spatial structure of the land surface. These results aid in identifying the dominant cross-scale nature of local to regional biosphere-atmosphere interactions.

AB The involvement of microRNA (miRNA) in various developmental programs in plants, such as leaf and flower development, and the response of plants to biotic and abiotic stresses, has been characterized. Information on the involvement of miRNA in seed biology is limited, but emerging. miRNAs and transcription factors or other genes that are targeted by miRNA are expressed during embryogenesis, seed maturation, imbibition, and seedling establishment, suggesting that the downregulation of target genes by miRNA may play a critical role in seed development and germination. This chapter focuses on the biological function of miRNA and miRNA-targeted genes involved in seed formation, the sensitivity of mature seeds to plant hormones, and postembryonic seedling development.

AB Trees are spectacular organisms that can accumulate a large amount of biomass, live for millennia, grow in stressful environments, and have global importance to organisms and human society as a result of their roles in contributing to diverse ecosystem services. They survive in an enormous range of environments with disturbances of various frequencies and severities, and by their very nature of being long-lived and sessile, they must possess the ability to change. This chapter provides a context for the chapters that follow, by describing a history of the investigations and of several important technological innovations that have enabled research to progress, and some of the foundations of water relations which underpin many of the later chapters. The chapter then discusses seven recurrent themes brought out by the diverse chapter authors: microclimate and other abiotic forces that change with tree and stand age; the changing structure and function employed as trees grow; what we can learn from scaling -which scaling laws pertain, when, and what is the biology or physics embedded in these laws; the tradeoffs that occur as structures and functions change through growth and development; the causes and correlates of the decline in productivity of trees and stands with age; the extent to which changes are plastic; and the meaning of whether changes occur relative to age versus size. The chapter concludes with a discussion on the emerging issues and questions raised in the chapters of this book. The overall aim is to give insights into the whole tree, whole lifespan perspective of the structural and functional strategies trees employ to persist in the face of internal and external factors that change as trees grow and age. This knowledge can be used to develop management approaches to manipulate trees and stands to provide a wide range of ecosystem goods and services.

AB Understanding how tree size impacts leaf- and crown-level gas exchange is essential to predicting forest yields and carbon and water budgets. The stable carbon isotope ratio (delta C-13) of organic matter has been used to examine the relationship of gas exchange to tree size for a host of species because it carries a temporally integrated signature of foliar photosynthesis and stomatal conductance. The carbon isotope composition of leaves reflects discrimination against C-13 relative to C-12 during photosynthesis and is the net result of the balance of change in CO2 supply and demand at the sites of photosynthesis within the leaf mesophyll. Interpreting the patterns of changes in delta C-13 with tree size are not always clear, however, because multiple factors that regulate gas exchange and carbon isotope discrimination (Delta) co-vary with height, such as solar irradiance and hydraulic conductance. Here we review 36 carbon isotope datasets from 38 tree species and conclude that there is a consistent, linear decline of Delta with height. The most parsimonious explanation of this result is that gravitational constraints on maximum leaf water potential set an ultimate boundary on the shape and sign of the relationship. These hydraulic constraints are manifest both over the long term through impacts on leaf structure, and over did l periods via impacts on stomatal conductance, photosynthesis and leaf hydraulic conductance. Shading induces a positive offset to the linear decline, consistent with light limitations reducing carbon fixation and increasing partial pressures of CO2 inside of the leaf, p(c) at a given height. Biome differences between tropical and temperate forests were more important in predicting Delta and its relationship to height than wood type associated with being an angiosperm or gymnosperm. It is not yet clear how leaf internal conductance varies with leaf mass area, but some data in particularly tall, temperate conifers suggest that photosynthetic capacity may not vary dramatically with height when compared between tree-tops, while stomatal and leaf internal conductances do decline in unison with height within canopy gradients. It is also clear that light is a critical variable low in the canopy, whereas hydrostatic constraints dominate the relationship between Delta and height in the upper canopy. The trend of increasing maximum height with decreasing minimum A suggests that trees that become particularly tall may be adapted to tolerate particularly low values of p(c).

AB Components of the tree water transport pathway; roots, trunks, branches and leaves; can also serve as water storage compartments and therefore act transiently as intermediate sources of water for transpiring leaves. However, most previous work has focused on gradual depletion and recharge of tree internal water reserves as soil water availability varies over seasonal cycles. This chapter focuses on the underappreciated role that internal water storage plays in stabilizing the physiological function of trees under the dynamic conditions that prevail over the course of a day. Capacitive discharge of water into the transpiration stream can buffer daily fluctuations in xylem tension, thereby diminishing the risk of xylem embolism and hydraulic failure under dynamic conditions. Intrinsic sapwood capacitance and reliance on stored water increase with tree size. An inverse relationship between sapwood capacitance and resistance to embolism across diverse woody species suggests that above a minimum threshold value of capacitance, the tree survives by using capacitance to provide hydraulic safety by buffering fluctuations in tension, rather by relying on xylem structural features that directly reduce vulnerability to embolism. Progress in understanding the physiological role of capacitance in trees is impeded by non-uniformity in the way capacitance is measured and expressed, preventing much of the available information from being synthesized. To remedy this, standard protocols are described for defining and expressing capacitance and water storage capacity.

AB Xylem pressure at the tops of trees decreases with increasing tree height as a result of gravitational force and friction associated with water movement through the xylem. Unless altered by osmotic adjustment, the turgor of cells in the apical and vascular meristems will decline proportionally with xylem pressure. In the tallest coniferous species on earth osmotic adjustment is insufficient to compensate for the negative impact of vertical gradients of xylem pressure on turgor of developing and mature tissue. This chapter synthesizes the research addressing turgor-related constraints on growth at the cellular, tissue, and whole tree levels. We examine the role of turgor in plant growth and foliar and stem structural and functional characteristics as they are influenced by height-related trends in turgor. We also evaluate height-related trends in turgor as a cause of observed patterns of tree height and tree biomass growth with an emphasis on how reductions in turgor can influence sink/source relationships for photosynthate in tall trees. Height-related reductions in cell turgor generate a cascade of direct and indirect effects on shoot extension and expansion. The multiple consequences of turgor-limited growth may act in a synergistic manner to further constrain shoot extension as trees approach species- and site-specific height limits. Turgor-limited tissue expansion has permanent anatomical and morphological consequences that govern height-dependent changes in an array of growth-related physiological processes. These include the impact of reduced xylem conduit dimensions on efficiency of water supply to growing tissues at the terminal portions of the water transport pathway, reduced growth efficiency associated with increased leaf mass per area, and increased resistance to CO2 diffusion through the mesophyll to the sites of carboxylation.

AB Three test sections were established in 2005 along a portion of the Kancamagus Highway in New Hampshire, where different reconstruction techniques were used: conventional (box-cut) reconstruction, full-depth reclamation (FDR), and FDR with cement-treated base. During the 2005-2006 winter and spring, elevation surveys were conducted to examine frost heave behavior. In 2006, those three test sections were folded into a larger research project sponsored by the New Hampshire Department of Transportation and the U.S. Department of Agriculture's Forest Service. For that project, extensive falling weight deflectometer (FWD) testing was conducted during the 2008 spring-thaw period to investigate variations in pavement stiffness that result from seasonal changes in temperature and moisture. An additional elevation survey was conducted in July 2009 to check for rutting in the wheelpaths. Results of this research suggest that FDR provides an economical and environmentally friendly alternative for reconstruction of low-volume roads. The 2005-2006 data show that the two FDR test sections exhibited more frost heave than the box-cut section, presumably due to frost-susceptible sub-grade soils that remained in place in those sections. However, the 2008 FWD data suggest that the overall stiffness of all three test sections was similar. Five years after initial reconstruction, survey data indicate that little to no rutting has occurred. Visual inspection revealed some cracking, with most of the observed distress attributed to thermal cracking on all three test sections.

AB Winter CO(2) fluxes represent an important component of the annual carbon budget in northern ecosystems. Understanding winter respiration processes and their responses to climate change is also central to our ability to assess terrestrial carbon cycle and climate feedbacks in the future. However, the factors influencing the spatial and temporal patterns of winter ecosystem respiration (R(eco)) of northern ecosystems are poorly understood. For this reason, we analyzed eddy covariance flux data from 57 ecosystem sites ranging from similar to 35 degrees N to similar to 70 degrees N. Deciduous forests were characterized by the highest winter R(eco) rates (0.90 +/- 0.39 gCm(-2) d(-1)), when winter is defined as the period during which daily air temperature remains below 0 degrees C. By contrast, arctic wetlands had the lowest winter R(eco) rates (0.02 +/- 0.02 gCm(-2) d(-1)). Mixed forests, evergreen needle-leaved forests, grasslands, croplands and boreal wetlands were characterized by intermediate winter R(eco) rates (g Cm(-2) d(-1)) of 0.70(+/- 0.33), 0.60(+/-0.38), 0.62(+/-0.43), 0.49(+/-0.22) and 0.27(+/-0.08), respectively. Our cross site analysis showed that winter air (T(air)) and soil (T(soil)) temperature played a dominating role in determining the spatial patterns of winter R(eco) in both forest and managed ecosystems (grasslands and croplands). Besides temperature, the seasonal amplitude of the leaf area index (LAI), inferred from satellite observation, or growing season gross primary productivity, which we use here as a proxy for the amount of recent carbon available for R(eco) in the subsequent winter, played a marginal role in winter CO(2) emissions from forest ecosystems. We found that winter R(eco) sensitivity to temperature variation across space (Q(S)) was higher than the one over time (interannual, Q(T)). This can be expected because Q(S) not only accounts for climate gradients across sites but also for (positively correlated) the spatial variability of substrate quantity. Thus, if the models estimate future warming impacts on R(eco) based on Q(S) rather than Q(T), this could overestimate the impact of temperature changes.

AB Biological control of plant-parasitic nematodes can be accomplished either by application of antagonistic organisms, conservation and enhancement of indigenous antagonists, or a combination of both strategies. The application of biological control has been inconsistent in suppressing nematode populations because the efficacy of antagonists is influenced by other soil organisms and the host-plant. Integration of biological control with nematicides, solarization, organic amendments, and crop rotation has also had varied success. Progress in biological control of nematodes has been hampered by the opaque nature of soil, the microscopic size of nematodes and their antagonists, and the complex interactions among soil organisms. Molecular biology offers new tools that will aid in determining which organisms are involved in naturally-suppressive soils, the fate of introduced antagonists, and how populations of indigenous and introduced antagonists change seasonally and with different crop production practices. Moreover, organisms have been engineered to over-express traits that enhance their activity against plant-parasitic nematodes.

AB Few studies have estimated the effect of environmental amenities on the rental price of houses. We address this gap in the literature by quantifying the effect of urban trees on the rental price of single-family homes in Portland, Oregon, USA. We found that an additional tree on a house's lot increased monthly rent by $5.62, and a tree in the public right of way increased rent by $21.00. These results are consistent with a previous hedonic analysis of the effects of trees on the sales price of homes in Portland, which suggests that homeowners and renters place similar values on urban trees.

ID STORAGE; SEQUESTRATION; RESOURCE; TREES; USA
AB While the urban forest is considered an eligible source of carbon offset credits, little is known about its market potential and the quality aspects of the credits. As credit suppliers increase in number and credit buyers become more interested in purchasing carbon credits, it is unclear whether and how urban forest carbon credits can perform relative to the other types of carbon credits available in the market. Delivering quality credits would be crucial especially in voluntary markets such as the U.S., where buyers are more likely to be committed to reducing their GHGs emissions and maintaining a positive public image, than just abiding by regulations. Utilizing the results of a nationwide survey of local governments. this study takes a first step toward evaluating the quality aspects of urban forest carbon credits. We conclude that the local municipalities and cities in the U.S., acting as sellers of carbon credits, have the resources and capacity to be competitive in carbon credit markets. In addition, they have capacity and resources to implement carbon projects that will meet the key quality criteria (e.g., additionality, permanence, and verification). (C) 2011 Elsevier GmbH.

AB A high-throughput transformation system previously developed in our laboratory was used for the regeneration of transgenic plum plants without the use of antibiotic selection. The system was first tested with two experimental constructs, pGA482GGi and pCAMBIAgfp94(35S) that contain selective marker and reporter genes. Transformation was monitored by GUS detection, and estimated transformation efficiencies were 5.7% and 17.7% for pGA482GGi and pCAMBIAgfp94(35S), respectively. Subsequently, an intron-hairpin-RNA (ihpRNA) construct, carrying the Plum Pox Virus coat protein (ppv-cp) gene, without selectable or reporter marker genes was designed. Five transgenic lines were regenerated as confirmed by DNA blot analysis. We believe that this is the first report on the production of marker-free plants transformed with a potential agronomically important trait in a Prunus species.

AB Avalanche hazard evaluation relies in part on representative snowpack stability observations. Thus, understanding the spatial patterns of snowpack instabilities and their environmental determinants is crucial. This case study integrates intensive field observations with spatial modeling to identify associations between incoming radiation, surface hoar development and its subsequent shear strength across an inclined forest opening. We examined a buried surface hoar layer in southwest Montana, USA, over five sampling days, collecting 824 SnowMicroPen resistance profiles and performing 352 shear frame tests. Spatial models of incoming long- and shortwave radiation were generated for the surface hoar formation period using modeled hemispheric sky visibility, physically based parameters and the Bird Clear Sky Radiation Model in a Geographic Information System. Before burial, the surface hoar persisted despite moderate winds and relatively high air temperatures. The buried surface hoar layer thickness varied between 3 and 21 mm within a distance of 30 m. Modeled incoming radiation explained spatial variations in layer thickness and shear strength. In areas exposed to large amounts of radiation, the surface hoar layer was strong and thin, while areas with limited incoming radiation (due to high sky visibility and shading) possessed a thicker surface hoar layer that sheared more easily. This demonstrates the usefulness of microclimate modeling for slope-scale avalanche hazard evaluation. We also identify that over the 3 week sample period, strengthening occurred without thinning of the surface hoar layer.

TI EFFECT OF CHITOSAN MOLECULAR WEIGHT ON RHEOLOGICAL BEHAVIOUR OF CHITOSAN

AB Effect of chitosan molecular weight (M(cs)) on the rheological properties of chitosan-modified clay (CMCs) at highly hydrated state was investigated. With special emphasis on its effect on the thixotropy of CMCs, the structure recovery at rest after underwent a pre-shearing process was further performed by the oscillatory shear measurements in the linear viscoelastic region. It was observed that both stress-strain behaviour and moduli of CMCs are closely correlated to M(cs). An interesting slope transition from negative to positive in the tan delta versus Ig omega plot is observed at omega = 2.5 rad/s. The value of tan delta < 0.5 over the entire range of frequency suggests a strong association in CMCs and a dominant elastic response of CMCs. Small peak-like transition of the shear viscosity, which denotes the yield region of the CMCs network, shifts to high shear rate with the increase of M(cs). Remarkably different thixotropic behaviour of these considered CMCs are observed relating to M(cs).G'(After) of CMCs with high M(cs) shows a linearly monotonic increase with the increase of the testing time, which well matches the power law of G'(After) similar to t(n). G'(After) of those CMCs with low M(cs), however, is distinctly deviated from the power law and possesses an exponential increase. The deviation of G'(After) becomes more marked with the decrease of M(cs). Furthermore, the effect of the pre-shearing history on the thixotropic properties of CMCs is performed by employing a large range of the pre-shear rate. Analysis of the empirical Cox Merz rule indicates a failure of the rule in CMCs system. CMCs prepared from low M(cs) chitosan are easier to be orientated at low shear rate.

AB Individual cuttings from five shrub species were burned over a flat-flame burner under wind conditions of 0.75-2.80 m s(-1). Both live and dead cuttings were used. These included single leaves from broadleaf species as well as 3 to 5 cm-long branches from coniferous and small broadleaf species. Flame angles and flame lengths were determined by semi-automated measurements of video images. Additional data, such as times and temperatures corresponding to ignition, maximum flame height and burnout were determined using video and infrared images. Flame angles correlated linearly with wind velocity. They also correlated with the Froude number when either the flame length or flame height was used. Flame angles in individual leaf experiments were generally 50 to 70% less than flame angles derived from Froude number correlations reported in the literature for fuel-bed experiments. Although flame angles increased with fuel mass and moisture content, they were unaffected by fuel species. Flame lengths and flame heights decreased with moisture contents and wind speed but increased with mass. In most cases, samples burned with wind conditions ignited less quickly and at lower temperatures than samples burned without wind. Most samples contained moisture at the time of ignition. Results of this small-scale approach (e.g. using individual cuttings) apply to ignition of shrubs and to flame propagation in shrubs of low bulk density. This research is one of the few attempts to characterise single-leaf and small-branch combustion behaviour in wind and is crucial to the continued development of a semi-empirical shrub combustion model.

AB Broadcast seeding is one of the most commonly used post-fire rehabilitation treatments to establish ground cover for erosion control and mitigation of non-native plant species invasions. Little quantitative information is available on overall trends of post-fire seeding expenditures and seed mixes used over time in forested ecosystems in the western USA. We reviewed scientific articles, government publications and unpublished documents as well as USDA Forest Service Burned Area Reports to determine trends in post-fire seeding in forested ecosystems over time. Of 1164 USDA Forest Service Burned Area Reports, 380 contained information on seeding treatments conducted in forested ecosystems. A review of 40 papers and 67 Burned Area Reports reporting species seeded between 1970 and 2007 revealed a trend of increasing use of native species, annual cereal grains and sterile-grass hybrids, with natives dominating seed mixes. According to 380 Burned Area Reports with data on costs and area seeded, total post-fire seeding expenditures have increased substantially, averaging US$3.3 million per year spent on post-fire emergency seeding treatments in forested ecosystems that involved the Forest Service during the period 2000 to 2007 - an increase of 192% compared with the average spent during the previous 30 years. The percentage of the total burned area seeded averaged 21% in the 1970s, compared with only 4% between 2000 and 2007.

AB In this study, eight commercial and three feral bumble bee (Bombus impatiens Cresson and Bombus pensylvanicus DeGeer respectively, Hymenoptera: Apidae) colonies were tested for the presence of Kodamaea ohmeri(Ascomycota: Saccharomycotina), a yeast known to attract small hive beetles (SHB) (Aethina tumida Murray, Coleoptera: Nitidulidae) to honey bee (Apis mellifera L, Hymenoptera: Apidae) colonies. Swabs of commercial bumble bee colonies and homogenates of bumble bee colony components (adults, brood, honey, pollen and wax) were plated on selective media. The resulting yeast isolates were compared to K. ohmeri previously isolated from SHB. Yeasts were detected in all of the commercial bumble bee colony swab samples (n = 56) and a selected subsample was shown through molecular, chemical, and microbiological evidence to be K. ohmeri: For the second part of the study, feral bumble bee colonies were excavated and evaluated for the presence of any SHB life stage (none was found). Adult bees and swabs from the colonies were plated on selective media. Kodamaea ohmeri was isolated in all samples collected from the feral bumble bee colonies. The presence of K. ohmeri in commercial and feral bumble bee colonies is of concern, as SHB, which harbour K ohmeri; are attracted to the volatiles produced by K ohmeri growing on bee collected pollen.

ID ALFALFA LEAFCUTTING BEE; LOCATION
AB The alfalfa leafcutting bee, Megachile rotundata F. (Hymenoptera: Megachilidae), is an important pollinator for the commercial production of alfalfa seed. Poor nest establishment is, however, an ongoing problem for bee managers. Megachile rotundata are solitary yet gregarious bees that nest in pre-existing cavities and are attracted to previously used nests. Nest cells contain several components that may serve as cues for nesting females. In the current study, we sought to: 1. determine if there is a preference for cells that previously held male or female conspecific bees; 2. verify attraction to conspecific whole nest cells; and 3. determine which individual nest components of a cell are attractive to nesting females. In a series of cage and open field experiments, M. rotundata females were allowed to initiate nests in blocks containing whole cells or individual cell components from old nests. Statistical analyses of results verified the attraction to conspecific nest cells, with no preference for male or female cells. Females were equally attracted to whole cells from conspecifics and from another megachilid bee, Osmia lignaria. In field cages, females were equally attracted to all cell components, but preferred some cell components over others in open field experiments. These results provide a foundation for future studies to identify potential chemical lures to aid in the retention of bee populations at commercial nest sites.

ID MANAGEMENT PRACTICE ADOPTION; FARM
AB Current federal and state soil and water conservation programs consist primarily of cost-sharing or compensating farmers for implementing a set of pre-defined best management practices. This approach does not consider specific environmental outcomes or the cost-effectiveness of the program at the farm or watershed level. Performance-based incentives are payments that are attached to a specified environmental performance measure, for example a reduction in nutrient, sediment, pesticide, or bacteria loss from a field, or reduction in loading at the mouth of a watershed. Assessing environmental performance requires the definition of a performance measure, which is used to calculate resulting incentive payments. In this paper, we discuss issues related to the selection of a performance measure, such as the scale at which the performance is measured, modeling versus monitoring, and the ability of the measure to foster farmer learning and adaptive management. Numerous examples of performance measures adopted or considered by watershed stakeholders in several states are presented. Watershed managers, policy makers, and extension agents can consider this information to make informed choices among proposed approaches toward improving water quality in streams affected by agricultural nonpoint source pollution.

AB At least 1,065 introduced vertebrate species have been introduced in the United States and its territories, including at least 86 mammalian, 127 avian, 179 reptilian/amphibian, and 673 fish species. Examples in each major taxonomic group include domestic cat, small Indian mongoose, red fox, goat, pig, rabbit, rats, house mouse, gray squirrel, nutria, starling, Indian common myna, red-vented bulbul, brown treesnake, red-eared slider, brown trout, tilapia, and grass carp. We briefly review some of these species and the types of damage they cause. We then review the basic types of methods used for control or eradication of each taxonomic group, including physical, chemical, biological, and cultural methods. We discuss some of the challenges in managing these species, including issues with the use of toxicants, land access, public attitudes, and monitoring difficulties. Finally, we list some ongoing research and future research needs, including improved detection methods, improved attractants, improved barriers, improved capture methods, fertility control, and risk assessment methods [Current Zoology 57 (5): 559-567, 2011].

AB The purpose of this review is to summarize briefly the toxicology and current state of biomarker development for commercially important mycotoxins. Combining information about known exposure, clinical indicators and biomarkers will provide a potential bioinformatic 'silver bullet' for identifying disease causation in the most economical and definitive manner. There is no single diagnostic approach that can identify/pinpoint when a disease outbreak is due to exposure to a mycotoxin or even when a mycotoxin could be a possible contributing factor to a disease outbreak of unknown etiology. One major problem is that the dose-response studies necessary to reveal the threshold for changes in mechanism-specific biochemical alterations (mechanism-based biomarkers) often have not been statistically correlated with thresholds for disease progression and exposure biomarkers ( parent compound or a metabolite in tissues/fluids). The key is to better define the underlying biochemical changes and thresholds that ultimately lead to adverse effects. To accomplish this, the first site of action or more precisely, the proximate cause for all the downstream effects must be identified. The development of validated biomarkers is critical to the effort to reduce the existing uncertainty in the risk assessment of most mycotoxins and to be able to predict with some degree of certainty when a specific mycotoxin is a contributing factor in a disease outbreak.

AB Research methods to identify and characterize genes involved in mycotoxin biosynthetic pathways have evolved considerably. Before whole genome sequences were available (e. g. pre-genomics), work focused primarily on chemistry, biosynthetic mutant strains and molecular analysis of single or relatively small numbers of genes. In recent years, reductions in the cost of DNA sequencing technologies have made genomic methods more widely available. The availability of whole genome sequence for multiple mycotoxin-producing fungi has led to important discoveries both within single genomes and between genomes via comparative genomics (post-genomic). The ability to analyze simultaneously the expression of a large number of genes through expressed sequenced tags (ESTs) and microarrays (transcriptomics) has also had a significant impact on gene cluster identification. This chapter discusses the pre-genomics strategies used to identify toxin biosynthetic genes/gene clusters in fungi as well as more recently developed genomic strategies that greatly enhance the efficiency of the identification process. Pregenomic researchers focused on analysis of a small number of genes, while post-genomic researchers can compare genomes and examine transcription patterns of thousands of genes at a time to help define biosynthetically related genes involved in mycotoxin synthesis. An examination of two Fusarium secondary metabolites (SMs), the mycotoxins fumonisins and a perithecial pigment, provide models for similar studies of other fungi. The identification of additional mycotoxin gene clusters in other fungi will proceed significantly faster in the future using genomic technologies.

AB Stagonospora nodorum is a major pathogen of wheat in many parts of the world and particularly in Western Australia. The pathosystem is characterised by interactions of multiple pathogen necrotrophic effectors (NE) (formerly host-specific toxins) with corresponding dominant host sensitivity loci. To date, five NE interactions have been reported in S. nodorum. Two proteinaceous NE (ToxA and SnTox3) have been cloned and expressed in microbial systems. The identification of wheat cultivars lacking sensitivity to one or more NE is a promising way to identify cultivars suitable for use in breeding for increased resistance to this economically important pathogen.
The prevalence of sensitivity to the NE SnTox3 was investigated in 60 current Western Australian-adapted bread wheat (Triticum aestivum L.) cultivars. Infiltration of SnTox3 into seedling leaves caused a moderate or strong necrotic response in 52 cultivars. Six cultivars were insensitive and two cultivars exhibited a weak chlorotic response. Five of the cultivars that were insensitive or weakly sensitive to SnTox3 were noticeably more resistant to the disease. The 60 cultivars gave a very similar reaction to SnTox3 and to the crude S. nodorum SN15 culture filtrate demonstrating that SnTox3 is the dominant NE in this isolate. We conclude that a simple screen using both SnTox3 and ToxA effectors combined with simple greenhouse disease evaluation, will allow breeders to select cultivars that are more resistant to the disease, allowing them to concentrate resources on other still intractable breeding objectives.

AB Genetically modified crops expressing insecticidal proteins from Bacillus thuringiensis (Bt) have dramatically increased in acreage since their introduction in the mid-1990's. Although the insecticidal mechanisms of Bt target specific pests, concerns persist regarding direct and indirect effects on non-target organisms. In the field, spiders may be exposed to Bt toxins via multiple routes, including phytophagy and pollenivory, consumption of Bt-containing prey, and soil exudates in the detrital food web. Beyond direct toxicity, Bt crops may also have indirect impacts, including pleiotropic and prey-mediated effects. Here, we comprehensively review the literature and use meta-analyses to reveal that foliar spider abundance is unaffected by Bt corn and eggplant, while cotton and rice revealed minor negative effects and there were positive effects from potato. Moreover, the soil-dwelling community of spiders was unaffected by Bt corn and cotton, while positively impacted in potato. However, Bt crops had higher populations of both foliar and epigeal spiders than insecticide-treated non-Bt crops. The current risk-assessment literature has several caveats that could limit interpretations of the data, including lack of taxonomic resolution and sampling methods that bias the results in favor of certain spiders. These families responded differently to Bt crops, and spider responses to insecticides are species- and toxin-specific, thus highlighting the need for greater taxonomic resolution. Bt crops have become a prominent, and increasingly dominant, part of the agricultural landscape; understanding their interactions with spiders, a diverse and integral component of agroecosystems, is therefore essential.

AB The cereal cyst nematode, Heterodera avenue, occurs in at least seven western states of the USA and reduces grain yield in localised regions and in selected crop management systems. Virulence phenotypes for H. avenae populations in North America have not been reported. Nine individual assays in six experiments were conducted to determine the reactions of barley, oat and wheat cultivars to five H. avenue populations in the Pacific Northwest (PNW) states of Idaho, Oregon and Washington. Three populations were evaluated for virulence to 23 entries of the 'International Test Assortment for Defining Cereal Cyst Nematode Pathotypes', plus selected local cultivars and entries representing a greater diversity of resistance genes. The virulence phenotype(s) for populations of H. avenue in the PNW did not correspond to any of the 11 pathotypes defined by the Test Assortment. Five PNW populations exhibited affinities with Group 2 but were not defined by pathotypes Ha12 and Ha22. Reproduction was prevented or greatly inhibited by barley carrying the Rha3 resistance gene and by most carriers of Rha2 resistance, and by selected oat cultivars with multigenic resistance. Wheat cultivars carrying the Cre1 resistance gene were highly effective in suppressing H. avenae reproduction. Current PNW wheat cultivars do not carry the Cre1 resistance gene. Crosses between Ouyen, an Australian bread wheat with Cre1 resistance, and several PNW wheat cultivars were resistant. The CreR gene also prevented H. avenue reproduction in the trial where it was tested. Intermediate levels of reproduction occurred on wheat cultivars carrying the Cre5, Cre7 and Cre8 resistance genes, each of which was considered useful for pyramiding into cultivars with Cre1 resistance. This research identified genetic resources of value in PNW cereal crop breeding programmes.

AB A novel and facile one-step approach to in situ synthesize silver nanoparticle-filled nylon 6 nanofibers by electrospinning is reported. The method does not need post-treatments and can be carried out at ambient conditions without using additional chemicals. It employs the electrospinning solvent as a reducing agent for in situ conversion of AgNO(3) into silver nanoparticles during the solution preparation. The resultant silver nanoparticle-filled nylon 6 hybrid nanofibers show an excellent fibrous structure (fiber diameter at 50-150 nm), with narrow size 2-4 nm silver nanoparticles uniformly dispersed throughout the nylon 6 matrix. DSC analysis shows that the in situ incorporation of silver nanoparticles increased the T(g) and crystallinity of the resultant nanofibers. These silver nanoparticle-filled nylon 6 nanofibers exhibit a steady and long-lasting silver ion release behavior, and robust antibacterial activity against both Gram-positive B. cereus and Gram-negative E. coli microorganisms.

AB Controlling wildfire suppression expenditures has become a major public policy concern in the United States. However, most policy remedies have focused on the biophysical determinants of suppression costs: fuel loads and weather, for example. We show that two non-biophysical variables-newspaper coverage and political pressure-have a significant effect on wildfire suppression costs. Hausman tests showed that newspaper coverage and fire size were endogenous, so regression models were estimated using two-stage least squares. We suggest a number of non-biophysical policy remedies that may be able to reduce wildfire suppression expenditures more cost-effectively than traditional biophysical remedies such as fuel management.

AB Conservation of genetic diversity is important for continued evolution of populations to new environments, as well as continued availability of traits of interest in genetic improvement programs. Rapidly changing climates present new threats to the conservation of forest genetic resources. We can no longer assume that in situ reserves will continue to preserve existing genetic diversity. Management of reserves should become more active. In some reserves, existing genetic diversity should be preserved by creating stands that are more resistant to threats using silvicultural treatments such as thinning and prescribed burning. In other reserves, natural selection and adaptation to changed environments should be promoted by increasing within population genetic diversity and promoting gene flow. This may be done by locating reserves in areas of high environmental heterogeneity, minimizing fragmentation, and using assisted colonization to increase genetic diversity by establishing populations adapted to future climates within or adjacent to reserves. Threats to native stands from climate change and other interacting threats should bring a renewed importance to ex situ collections, particularly for rare and disjunct populations and those at the warmer and drier edges of a species range. Assisted colonization to move threatened populations to new environments must be considered as an additional conservation measure.

AB In this study, we evaluated the influences of 3 Agrobactrium rhizogenes strains (15384, A4, and K599), 4 different tissue types (internodes, stem-cut and petiole-cut surfaces on in vitro plants, and young shoots excised from in vitro plants), and 14 Vitis species (Vitis cinerea, V. champinii, doaniana, V. ficifolia, V. flexuosa, V. girdiana, V. jacquemontii, labrusca, V. nesbittiana, V. novae-angliae, V. palmata, V. piasezkii, V. treleasii, and V. vinifera) on the induction of transgenic hairy roots. Our results revealed that both 15834 and A4, but not K599, were effective in inducing hairy roots in Vitis species and that different Vitis species and tissue types responded differently to hairy root induction. Among the 14 species evaluated, V. champinii, V. cinerea, V. labrusca, V. treleasii, and V. vinifera-1044 produced hairy roots within a 2-week observation period when the induction was carried out on in vitro plants. Compared with the tissues of stem-cut and petiole-cut surface, the internode tissue showed a higher efficiency for hairy root induction. We further revealed that when young shoots were excised from in vitro plants and used as inoculation material, the overall induction efficiency of hairy roots could be much improved. In addition, we also investigated the feasibility of producing composite plants with transgenic hairy roots and non-transgenic shoots. Although a number of such in vitro composite plants were established from inoculated young shoots, none of them were successfully maintained after being transplanted to pot soil.

AB Despite the ubiquity of denning as a natural history strategy among terrestrial vertebrates, little is known regarding basic patterns of within-den behavior, how such patterns are influenced by demographic and environmental parameters, or how within-den behavioral repertoires relate to activities performed in external environments. Den usage is believed to facilitate increased expression of behaviors that compromise fitness in external environments, though empirical data validating these assumptions are generally lacking. Relative isolation from external light cues within dens has been linked to temporal patterns of den use, yet few studies examine associations between photoperiod and rhythmicity strictly for within-den behavior. Also, for denning species with relatively equivalent parental investment, conclusions regarding sex-specific behavior have been equivocal, and no studies have examined potential segregation of parental activity within dens. We videorecorded 1506 h of within-den activity from 23 beaver (Castor canadensis) colonies and characterized behavioral patterns based on sex and age over daily and monthly intervals. Within-den time-activity budgets were equivalent among male and female adult beavers, with feeding, sleeping, allogrooming, and individual grooming accounting for more than 95% of all recorded behaviors. Behavioral repertoires within dens exhibited distinct seasonality and were influenced by temporal variation in external conditions associated with food availability, indicating linkages between activities within and outside of dens. Lastly, beaver age classes varied considerably in their associations between dial activity patterns and photoperiod, with adults and kits exhibiting single and multiple sleep-wake cycles, respectively.

AB Both nutrient concentrations and pre- and post-harvest pool sizes were determined across down woody debris decay classes of several hardwood and softwood species in a long-term, natural disturbance based, silvicultural experiment in central Maine. Concentrations of N, P. Ca, Mg, Cu, Fe, and Zn generally increased 2- to 5-fold with increasing decay class. Concentrations of Mn, Al and B did not differ among decay classes, while K decreased by 20-44% from decay class 1 to class 4. C:N-ratios declined with increasing decay class, while N:P-ratios increased from decay class 1 to 2 and then plateaued with further decay. Within decay classes, softwoods generally had lower nutrient concentrations and higher C:N-ratios than hardwoods; N:P-ratios did not differ between hardwoods and softwoods. Although gap harvesting increased the size of the overall clown woody debris nutrient pools, mostly through a large pulse of decay class I material, harvesting generally reduced the nutrients held in advanced decay classes. Pre-harvest down woody debris pools for N. P. K and Ca were 11.0, 0.6, 2.1 and 21.1 kg ha(-1), respectively, while postharvest were 20.0, 1.3, 6.2 and 46.2 kg ha(-1), respectively. While the gap-based silvicultural systems sampled in this study doubled the size of the pre-harvest, downed woody debris nutrient pools, the post-harvest pools were estimated to be only 3.2-9.1% of aboveground nutrients.

AB Sustainable land use is the management of the natural environment and the built environment to conserve the resources that help to sustain the current local human population and that of future generations. This review serves three purposes. First, it gives an introduction to the concept of sustainability in relation to land use, assessing what is "unsustainable" and what is "sustainable." The environmental, historical, and social context is described for understanding current land-use practices. But this will not suppress the demand for viable developmental processes and the potential collateral effects in order to avoid resource depletion. Where natural resources exist, exploitation needs to be adjusted to carrying capacity that is, it must be determined to what degree the environment is capable of absorbing the impact of the development. As agricultural soil is the foundation for nearly all land uses, soil quality stands as a key indicator of sustainable land use. Second, land use and its mismanagement of arable areas by farmers and grazing areas by livestock is addressed as one of the major causes of soil degradation. This result from erosion, decline in fertility, changes in aeration and soil-water content, salinization, or a change in soil flora or fauna. By reflecting the basic functioning capacity of the soil, it is the measure of many potential uses. On the other hand, management policy will have to adapt agriculture to climate change by encouraging flexibility in land use, crop production, and farming systems. In doing so, it is necessary to consider the multifunctional role of agriculture and to strike a versatile balance between economic, environmental, and social functions in different regions and sectors. Also, attention needs to be paid to all issues concerning agricultural strategies in order to mitigate climate change through a reduction in emissions of greenhouse gases, by increasing carbon sequestration in agricultural soils and mediating the growth of energy crops as substitutes for fossil fuels. Third, it concludes that sustainable land use in agricultural systems involves readjusting unsuitable land use and promoting the appropriate use of land for sustainable systems. This review discusses some of the fundamental tasks and examines why sustainable land-use practices and innovations need to be adopted, providing a perspective of close collaboration among scientists, land managers, and policymakers.

AB Fire management will face many challenges in the future from global climate change to protecting people, communities, and values at risk. Simulation modeling will be a vital tool for addressing these challenges but the next generation of simulation models must be spatially explicit to address critical landscape ecology relationships and they must use mechanistic approaches to model novel climates. This chapter summarizes important issues that will be critical for wildland fire management in the future and then identifies the role that simulation modeling can have in tackling these issues. The challenges of simulation modeling include: (i) spatial representation, (ii) uncertainty, (iii) complexity, (iv) parameterization, (v) initialization, (vi) testing and validation. The LANDFIRE project is presented as an example on how simulation modeling is used to support current fire management issues. Research and management needs for successful wildland fire-related simulation modeling projects will need (i) extensive mechanistic research programs, (ii) comprehensive databases, (iii) statistical validation methods and protocols, (iv) software and hardware research, (v) modeling science explorations, and (vi) extensive training. Models will continue to play an integral role in fire management but only if the science keeps pace and managers are poised to take advantage of advances in modeling.

AB Managers of forested landscapes must account for multiple, interacting ecological processes operating at broad spatial and temporal scales. These interactions can be of such complexity that predictions of future forest ecosystem states are beyond the analytical capability of the human mind Landscape disturbance and succession models (LDSM) are predictive and analytical tools that can integrate these processes and provide critical decision support information. We briefly review the state of the art of LDSMs and provide two case studies to illustrate the application and utility of one LDSM, LANDIS. We conclude that LDSMs are able to provide useful information to support management decisions for a number of reasons: (i) they operate at scale that is relevant to many forest management problems, (ii) they account for interactions among ecological and anthropogenic processes, (iii) they can produce objective and comparable projections of alternative management options or various global change scenarios, (iv) LDSMs are based on current ecological knowledge and theory, (v) LDSMs provide a vehicle for collaboration among decision-makers, resource experts and scientists, (vi) LDSMs are the only feasible research tool that can be used to investigate long-term, large area dynamics.

AB Three-dimensional (3D) visualization is a useful tool that depicts virtual forest landscapes on computer. Previous studies in visualization have required high end computer hardware and specialized technical skills. A virtual forest landscape can be used to show different effects of disturbances and management scenarios on a computer, which allows observation of forest landscapes without time limitations. This chapter lists updated methods and software used for 3D visualization of forest landscapes, and demonstrates a fire visualization using Visual Nature Studio and standard computer hardware. Elevation and vegetation data were used to create a representation of the New Jersey pine barrens environment. Photographic images were edited to use as image object models for forest vegetation. The FARSITE fire behavioral model was used to model a fire typical of that area. Output from FARSITE was used to visualize the fire with tree models edited to simulate burning and flame models. Both static and animated views of the fire spread and effects were visualized. The visualization method was evaluated for advantages and disadvantages. VNS visualization is realistic, including many effects such as ground textures, lighting, user-made models, and atmospheric effects. However VNS has additional hardware requirements in terms or memory or hard drive space and sometimes renders images slowly.

AB We demonstrate an approach to integrated land-management planning and quantify differences in vegetation and avian habitat conditions among 5 management alternatives as part of the Hoosier National Forest planning process. The alternatives differed in terms of the type, extent, magnitude, frequency, and location of management activities. We modeled ecological processes of disturbance (e.g. tree harvest, prescribed fire, wildfire, windthrow) and succession using LANDIS, a spatially explicit landscape decision-support model, and applied habitat suitability models for six species of birds to the output from that model. In this way, we linked avian habitat suitability models to spatially explicit vegetation change models that include ecological processes affecting vegetation composition, horizontal and vertical structure, and configuration. The detailed and synthetic nature of our approach provides a framework and structure that (1) is readily conveyed to multiple constituencies, (2) is based on explicitly stated assumptions and relationships, (3) provides a basis for testing, refinement, and extension to other forest commodities and amenities, and (4) provides a way to consider cumulative effects of multiple forest attributes at multiple spatial and temporal scales.

AB Forest biodiversity is crucial to the ecological, economic, and social well-being of earth's civilisations. Unfortunately, however, forest biodiversity is threatened to a serious degree in nearly all countries. Therefore, many countries have agreed to be parties to international agreements focused on maintaining, restoring, and monitoring biodiversity; further, these countries have agreed to report to international bodies on the status and trends in forest biodiversity. NFIs are the primary source of large-scale information available for this purpose, but the large variety of definitions, protocols, sampling designs, and plot configurations used by NFIs makes comparable international reporting extremely difficult. COST Action E43 was initiated to address this problem by developing harmonization techniques that facilitate common reporting. Harmonization typically consists of two components: development of common international reference definitions and development of bridging techniques that facilitate estimation according to reference definitions using data collected according to national definitions. Working Group 3 of COST Action E43 has focused its harmonization efforts on issues related to biodiversity. The chapters and sections that follow document these efforts in detail.

AB Forest biodiversity assessments may be based on species or taxon groups, structural traits of forest ecosystems and/or biodiversity indicators derived from these variables. Working Group 3 (WG3) of COST Action E43 initially selected 41 candidate biodiversity variables based on current ecological knowledge. The next step entailed construction and distribution of a questionnaire regarding the importance of the candidate variables for assessing forest biodiversity and their feasibility for assessment by national forest inventories (NFI). Responses were received from 22 countries. Analyses of the responses with respect to importance and feasibility resulted in further selection of 17 biodiversity variables that were then grouped into seven essential biodiversity features: forest categories, forest age, forest structure, deadwood, regeneration, ground vegetation and naturalness. These seven essential features constitute the second level of WG3's 4-level reference framework: (1) concept, (2) essential feature, (3) indicator, and (4) NFI variable. This chapter addresses in detail the analyses of the questionnaire responses, selection of the 17 biodiversity variables, and derivation of the seven essential forest biodiversity features.

AB Following selection of the 13 biodiversity variables that were evaluated as both important and feasible for assessment by NFIs and grouping them into essential features, additional information was solicited regarding the degree to which the 13 variables are currently assessed by NFIs. The objective was to evaluate the prospects for harmonized estimates of biodiversity indicators based on these variables. The prospects varied considerably depending on the particular variable and essential feature. The evaluations produced positive harmonization possibilities for forest categories and the tree height and diameter variables associated with forest structure. For forest age, possibilities were constrained by lack of common reference definitions. However, possibilities for construction of a common reference definition and bridges to compensate for the differences in estimates resulting from using national and reference definitions were deemed positive. Prospects for regeneration, ground vegetation, and naturalness were less positive because of variability in definitions, assessment methods, measurement thresholds and other factors. Thus, efforts at harmonization for these essential features were constrained to a few variables or a few countries with similar NFI features.

ID FOREST MANAGEMENT
AB Chapter 5 reports the results of testing the proposed procedures for harmonizing estimates of indicators for six of the seven essential features of forest biodiversity. Twenty indicators were tested using data from the common database. In general, positive results were obtained for forest categories, forest structure, forest age, deadwood, and naturalness; the results were less positive for ground vegetation because of the considerable differences in definitions and data acquisition methods. Of importance is, that the test focused on assessing harmonization procedures rather than on producing comprehensive estimates for particular countries or forest categories.

AB Calcium is an essential plant nutrient, thus the influx of Ca2+ into plant cells is a critical process. In addition, the efflux of Ca2+ out of a cell is important to prevent toxicity resulting from Ca2+ excess, and to modulate levels of cytosolic Ca2+ required for signaling functions. Biochemical and genetic analysis of plants has begun to identify the complement of Ca2+-permeable channels and Ca2+-ATPases that function in Ca2+ flux across the plasma membrane. In addition to understanding the mechanisms of plasma membrane Ca2+ transport, some of the specific functions of these pathways are now emerging. Comparative genomics of higher plant, algal and moss species has identified significant variation in the mechanisms of plasma membrane Ca2+ transport between higher and lower plants, and provides insight into the evolution of Ca2+ transport processes.

AB The intestinal microbial ecosystem is a dense and diverse population that can be utilized to reduce pathogenic bacterial populations that affect animal production efficiency and the safety of food products. Strategies to capture and utilize this complex natural resource have been developed that reduce the populations of foodborne pathogenic bacteria and eliminate pathogens that negatively impact animal production or food safety on the farm. Products used in animals to reduce pathogens in the food supply include probiotics, prebiotics and competitive exclusion cultures, as well as bacteriocins and bacteriophage (bacterial viruses). The individual efficacy of any of these compounds is due to specific microbial ecological factors within the gut of the food animal and its native microflora that alter the competitive pressures of the gut. This review explores the ecology behind the efficacy of these products against foodborne pathogens that inhabit food animals.

AB The mosaic nature of the Salmonella enterica genome facilitates its access to multiple environments. Many large scale genomic events have been described that contribute to the combinatorial complexity of the pathogenic Salmonellae. However, the impact of small scale genetic change occurring at the level of single nucleotide polymorphism (SNP) on the emergence of niche specialization is just now becoming appreciated. This chapter describes concepts behind the evolution that culminated in the remarkable ability of Salmonella enterica serovar Enteritidis to contaminate and survive in the internal content of eggs produced by otherwise healthy hens. Evidence suggests that combinations of SNPs facilitate niche specialization by Salmonella enterica. However, few typing methods incorporate unbiased strategies for their detection. Selection of appropriate biological assays for ranking SNPs and combinations of SNPs for their impact on the ability of Salmonella enterica to propagate outbreaks, pandemics and disease will be a significant challenge to improve the safety of the food supply.

AB The aging process is characterized by the gradual decrease in muscle mass, strength and power leading to a decline in physical functioning, increased frailty and disability. This age related loss of muscle mass and function has been termed sarcopenia. The mechanisms that underlie sarcopenia are only beginning to be elucidated. However, specific modes and intensities of physical activity can both act to preserve and also increase skeletal muscle mass, strength, power in healthy and functionally limited older individuals. This effect appears to be pervasive throughout the lifespan and there is evidence for similar responses in men and women. The focus of this chapter is on the role of exercise as a therapeutic intervention for the prevention and treatment of sarcopenia. This will be accomplished by (1) reviewing the epidemiology on physical activity and sarcopenia (2) summarizing the molecular mechanisms associated with sarcopenia and exercise, (3) discussing the efficacy of resistance and endurance exercise or multi-modal exercise, such as the combination of aerobic and resistance exercise for the management of sarcopenia.

AB Recently the world has been entangled by insufficient food such as the lack of rice which threatens the safety of world food and affect sustainable development of the world economy, resulting in rising of food price. To address this issue, cotton appears as a possible source of both fiber and food. The research in recent years indeed showed bright prospects for this expectation. However, gossypol stored in the glands of cotton is toxic to nonruminant animals and humans, which wastes large amounts of cottonseed protein that could potentially provide the annual protein requirements for half a billion people. Gossypium species are characterized by their lysigenous glands containing terpenoid aldehydes, important secondary phytoalexins consisting mainly of gossypol, which constitute one of the important plant's defense system against pests and diseases. The best approach to address this issue is to create glandless seed and glanded plant cotton. A breakthrough in this field would realise the fulfilment of making cotton both a fiber and a food crop, which would be a feat of great magnitude for sustainable development of agriculture. Research on the relationship between glands and their secondary inclusions at the molecular level would be one approach for genetic engineering to control the glands and gossypol content. In this article, we review recent progress on glands and gossypol content for diverse gland types in Gossypium species, inheritance of glands and gossypol content, traditional breeding of glandless seeds and glanded plant cotton, the terpenoid aldehyde biosynthesis pathway, molecular cloning of the related genes, the strategy for genetic engineering, and future prospects.

AB About 4 billion people will be added onto the present population by 2050. To meet further demand for food, agricultural production should increase on the existing land. Since the Green Revolution, higher crop production per unit area has resulted in greater depletion of soil phytoavailable micronutrients while less attention has been paid to micronutrients fertilization. Now, micronutrient deficiency has become a limiting factor for crop productivity in many agricultural lands worldwide. Furthermore, many food systems in developing countries can not provide sufficient micronutrient content to meet the demands of their citizens, especially low-income families. There are several solutions such as soil and foliar fertilization, crop systems, application of organic amendments to correct micronutrients deficiency and to increase their density in edible parts of plants. This review article presents (1) agronomic approaches to improve crop yield and micronutrient content of food crops, and (2) genotypic variation in uptake and accumulation of micronutrients. Considering ecological concerns, cultivation and breeding of micronutrient-efficient genotypes in combination with proper agronomic management practices appear as the most sustainable and cost-effective solution for alleviating food-chain micronutrient deficiency. Micronutrient-efficient genotypes could provide a number of benefits such as reductions in the use of fertilizers, improvements in seedling vigor, and resistance to biotic and abiotic stresses. Using bioavailable micronutrient dense staple crop cultivars can also be used to improve the micronutrient nutritional status of human.

AB As animal agriculture has evolved to larger production operations in subtropical regions of United States, the problems associated with manure handling, storage and disposal have grown significantly. Understanding the interaction effects of sustainable cow farming with water-table management, nutrient dynamics and water quality in pastures could be the key to reducing nutrients in runoff. Soils do not contribute equally to nutrient export from watersheds or have the same potential to transport nutrient to runoff nor would soil test levels accurately predict total dissolved nutrients. Better understanding of soil nutrient dynamics and crop nutrient changes resulting from different management systems should allow us to predict potential impact on adjacent surface waters. In many states, these issues are critical and of increasing importance among environmentalists, ranchers, and public officials particularly in the case of N and P. One of the first steps in assessing N or P level on any farm is to consider total N or total P inputs and outputs. In Florida, reduction of P transport to receiving water bodies is the primary focus of several studies because P has been found to be the limiting nutrient for eutrophication in many aquatic systems. Long-term monitoring of the changes in soil nutrients, especially soil P would enable us to predict soil chemical or physical deterioration under continuous forage-livestock cultivation and to adopt measures to correct them before they actually happen. Despite substantial measurements using both laboratory and field techniques, little is known about the spatial and temporal variability of nutrient dynamics across the entire landscape, especially in agricultural landscapes with cow-calf operations.

AB The final outcomes of the approach of the anthroscape, seeking to develop a powerful tool for use by the local communities/administrations and relevant bodies for a bottom to top approach, as a quantified entity, means to direct the future land and water use decisions to be taken at lower levels - as farm domains etc. - leading to the development of an "Anthroscape Land Quality Class" map and the relevant "Ideal Land Use Patterns" of the Seyhan Anthroscape. These two final products of quantification are sought to be capable in revealing the magnitude and the distribution of the degradation of the selected area, as well as allocating the ideal land use types given for the percentages of the distributions of land except their specific location. In this context, the downstream part of the map will show the abundant degradation arising via the intensive cultivation practices where the class stated in the map reveals the urgent need of an integrated SLWM Programme to revert the lower class C and D ALQCs to higher ALQCs to meet the requirements of the sustainable use of the land. Whereas, the higher ALQC land in the transition or upstream zone stands for higher resilience and lower input requirements to meet the ideal use of the land. The Net Primary Production (NPP) - The remainder of photosynthesis and respiration which has significance in the global and regional carbon budgets and is a function of the standing biomass (an important component of the carbon cycle and a key indicator of ecosystem performance) was utilized via land cover and management to serve as a supplementary indicator of the Anthroscape and the Anthroscape Land Quality.

AB Anthroscapes are important in the assessment of human-induced land degradation. In case of soils affected by land use changes in large-scale farming, the anthropogenic processes have been created in China for over a few thousands years. The Chinese started to use soil for crop production as early as in the Stone Age. Soil properties in China and Taiwan have been greatly influenced by various anthropogenic processes to form anthroscapes. Paddy soils or rice-growing soils are more than 30 million hectares, distributed in China and Taiwan, which are one of the world's most important soil resources for food production. According to the Chinese Soil Taxonomy [ISS/CAS (Institute of Soil Science, Chinese Academy of Sciences) (ed.) (2001) Chinese Soil Taxonomy. Science Press, Beijing, 203p], Anthrosols meet the requirements of the combination of horizons, including anthrostagnic, fimic, siltigic and cumulic epipedons and the hydragic horizon. The changes of soil characteristics after planting rice are degradation of soil organic matter (SOM), redistribution of exchangeable bases, translocation and segregation of iron (Fe) and manganese (Mn) by the cycling of reduction And oxidation processes, as well as decomposition and synthesis of clay minerals. The genetic horizons of paddy soils in China and Taiwan include a cultivated gray horizon, a plowpan, a percogenic horizon, and a plinthitic horizon or illuvial horizon with various redoximorphic features. The landscape position is the major factor to control the duration of saturation and reduction in the paddy soils of Taiwan. An anthrogleyic epipedon in Taiwan was also common in the surface horizon in paddy soils. Irrigation has induced the enrichment of the soil organic carbon (SOC) stock in the paddy soils. The free Fe contents of paddy profiles tend to be increased as the length of cultivation history increases in China, but this trend is much less profound in non-paddy profiles.

DT Article; Book Chapter
DE Shifting cultivation; Sarawak; Impact analyses; Mismanaged systems
AB Shifting cultivation has a negative connotation particularly in western societies. It is viewed as a system that progressively deforests without attempts to regenerate the forests. Although the system is practiced in many developing countries its contributions to the forest ecosystem and the low-input agricultural system is not recognized. A major advantage is the biodiversity that prevails in this system in comparison to that which exists in the mono-clonal plantations. Mismanaged systems can lead to a land becoming a biodiversity-desert. Shifting cultivation, as practiced by the forest communities is a viable, sustainable enterprise but becomes compromised by modern interventions. Despite the negative connotations, the impact of shifting cultivation can be contained in a sustainable land management system. Precise data on spatial distribution of land areas affected by shifting cultivation is needed. The degradation potential of various fragile systems where shifting agriculture has been detected, can be ascertained with greater precision with such precise data.

AB Plant communities associated with the agricultural landscape are gradually getting impoverished and even eradicated and replaced by poor species in many places of the world. A large number of studies are now available about the interactions between root and the soil system. However, influence of plants on aggregate stability remains to be a complex issue. The aim of this work was to determine the changes in the soil quality indicators that have developed at the rhizospheres under the selected weeds in the abandoned land. The results confirmed significant changes on bio-diversity of weed communities in a succession of over a decade. There were only 14 weed species in the abandoned field in the spring of 1998. The survey in the spring of 2008 confirmed the presence of 34 species. A decadal abandonment of the prime soil of the Mediterranean environment proved to increase the amount of the water stable aggregates and the mycorrhizal activity along with the accumulation of the organic and available nitrogen.

AB Black-foot disease of grapevine is caused by a complex of soilborne fungi. The most common and virulent species, which are found across all major grapegrowing regions of the world, are Cylindrocarpon liriodendri (C. liriodendri) and C. macrodidymum (teleomorph = Neonectria). Other species with a more limited distribution and uncertainty regarding their pathogenicity include C. destructans, C. obtusisporum, C. pauciseptatum, Campylocarpon fasciculare (C. fasciculare), and C. pseudofasciculare. The goal was to identify the species associated with black-foot disease in vineyards of the northeastern United States (U.S.) and southeastern Canada as such regions have not previously been surveyed. Recent expansion of winegrape acreage in these regions necessitates a clear understanding of the disease risks. Eleven U.S. states and two Canadian provinces were surveyed. Genus-level identification was based preliminarily on colony morphology. Species-level identity was based on phylogenetic analysis of two nuclear loci, 5.8S rDNA and beta-tubulin, using voucher specimens and sequences with high sequence identity. We report for the first time from Canada recovery of C. liriodendri, C. macrodidymum, and C. destructans from symptomatic grapevines. Also reported are species not previously identified from black-foot symptomatic grapes anywhere in the world, including C. didymum and a Neonectria mammoidea-like species. Results suggest that local viticultural practices, primarily burying the vine underground during winter, may create injuries, and thus exacerbate infection by wound pathogens such as Cylindrocarpon. Overall this work improves the knowledge of black-foot disease in these nascent grapegrowing regions and will be helpful to growers in their decisions regarding viticultural practices, planting, and disease management.

AB Native sagebrush ecosystems in the Great Basin (western USA) are often invaded following fire by exotic Bromus tectorum (cheatgrass), a highly flammable annual grass. Once B. tectorum is established, higher fire frequencies can lead to local extirpation of Artemisia tridentata ssp. vaseyana (mountain big sagebrush) and have cascading effects on sagebrush ecosystems and the species that depend on them. We conducted a landscape-scale observational study to examine the distribution and cover of B. tectorum and A. tridentata 6 years after a large wildland fire. We used structural equation models to quantify the interacting influences of pre-fire tree canopy cover, perennial species cover, distance from potential seed source, and site environment on post-fire cover of B. tectorum and A. tridentata. Results confirmed a hypothesised negative effect of pre-fire tree canopy cover on post-fire cover of A. tridentata. Site-and landscape-level abiotic factors influenced pre-fire tree canopy cover, which, in turn, influenced the probability of rapid recovery to A. tridentata. However, B. tectorum cover was primarily influenced by a positive effect of incident solar radiation and a negative effect of perennial herbaceous species cover. Restoration efforts to reduce tree canopy cover should be limited to productive sites with sufficient cover of perennial herbaceous species to facilitate site recovery.

TI Control of Orange Hawkweed (Hieracium aurantiacum) in Southern Alaska
SO INVASIVE PLANT SCIENCE AND MANAGEMENT
LA English
DT Article
DE Alaska; exotic weeds; greenhouse; nonindigenous plant; weed control
AB Orange hawkweed is a perennial European plant that has colonized roadsides and grasslands in south-central and southeast Alaska. This plant is forming near-monotypic stands, reducing plant diversity, and decreasing pasture productivity. A replicated greenhouse study was conducted in 2006 and repeated in 2007 to determine the efficacy of six herbicides (aminopyralid, clopyralid, picloram, picloram + chlorsulfuron, picloram + metsulfuron, and triclopyr) for orange hawkweed control. Based on results of the greenhouse trials, replicated field studies were conducted at two sites each year in 2007 and 2008 with three rates each of aminopyralid and clopyralid to determine efficacy of orange hawkweed control and impacts on nontarget native vegetation. In the field, only aminopyralid at 105 g ae ha(-1) (0.1 lb ae ac(-1)) and clopyralid at 420 g ae ha(-1) controlled orange hawkweed consistently, with peak injury observed 1 yr after treatment. Control with clopyralid was slightly less than that provided by aminopyralid at all observation times, except at Homer, AK, in 2007, where there was a near-monotypic stand of orange hawkweed, and clopyralid did not remove all orange hawkweed plants. Aminopyralid controlled clover (Trifolium spp.), seacoast angelica (Angelica lucida), arctic daisy (Chrysanthemum arcticum), common hempnettle (Galeopsis tetrahit), and willow (Salix spp.) in the treated areas. Other plant species, such as grasses and some annual forbs, recovered or increased following control of the hawkweed. Clopyralid had less impact on nontarget species with most recovering the year after treatment. In a pasture system, where grasses are preferred to forbs and shrubs, aminopyralid has an advantage because it controls a broader array of forbs compared with clopyralid. In natural areas, where the desire to retain biodiversity and the aesthetics of multiple forb species mixed with grasses and willows is preferred, clopyralid will leave greater species diversity than aminopyralid.

AB Broom snakeweed is a native weed widely distributed on rangelands of western North America. It often increases to near monocultures following disturbance from overgrazing, fire, or drought. This paper presents an up-to-date review of broom snakeweed toxicology, seed ecology, population cycles, succession, and management. The greatest ecological concern is that broom snakeweed displaces desirable forage for livestock or wildlife and greatly reduces biodiversity. It also is toxic and can cause abortions in all species of livestock. Propagation usually is pulse-driven in wet years, allowing large expanses of even-aged stands to establish and dominate plant communities. Snakeweed can be controlled by prescribed burning or spraying with herbicides. A weed-resistant plant community dominated by competitive grasses can prevent or minimize its reinvasion.

AB Many perennial bioenergy grasses have the potential to escape cultivation and invade natural areas. We quantify dispersal, a key component in invasion, for two bioenergy candidates:Miscanthus sinensis and M X giganteus. For each species, approximately 1 X 10(6) caryopses dispersed anemochorously from a point source into traps placed in annuli near the source (0.5 to 5 m; 1.6 to 16.4 ft) and in arcs (10 to 400 m) in the prevailing wind direction. For both species, most caryopses (95% for M sinensis and 77% for M X giganteus) were captured within 50 m of the source, but a small percentage (0.2 to 3%) were captured at 300 m and 400 m. Using a maximum-likelihood approach, we evaluated the degree of support in our empirical dispersal data for competing functions to describe seed-dispersal kernels. Fat-tailed functions (lognormal, Weibull, and gamma (Gamma)) fit dispersal patterns best for both species overall, but because M. sinensis dispersal distances were significantly affected by wind speed, curves were also fit separately for dispersal distances in low, moderate, and high wind events. Wind speeds shifted the M. sinensis dispersal curve from a thin-tailed exponential function at low speeds to fat-tailed lognormal functions at moderate and high wind speeds. M. sinensis caryopses traveled farther in higher wind speeds (low, 30 m; moderate, 150 m; high, 400 m). Our results demonstrate the ability of Miscanthus caryopses to travel long distances and raise important implications for potential escape and invasion of fertile Miscanthus varieties from bioenergy cultivation.

AB Invasive plants are negatively affecting the ecological and economic production of rangelands by reducing resource productivity, decreasing biodiversity, displacing native vegetation, and altering ecosystem processes and functions. However, despite these well-known negative effects, once invasive plants are regionally established, limited effort is directed at preventing their continued spread across rangelands. Most efforts are directed at restoration at specific locations while additional rangelands are invaded. Restoring native plant communities invaded by exotic plants is frequently unsuccessful, especially in more arid environments, and is often too costly to apply at the scale required to make meaningful progress in reducing invasive plant populations relative to their expansion. Of the few prevention efforts being implemented, most are a second priority to control and restoration efforts. Integrating strategies to prevent new infestations and restrict the expansion of existing populations in invasive plant management programs is critical to limiting the negative effects of invasive plants in rangelands. However, we are "missing the boat" on this issue by not providing sufficiently developed and validated management actions. Limited information is available for developing management strategies to prevent the spread of invasive plants, although it has been suggested that land managers need to increase biotic resistance of desired plant communities, decrease invasive plant propagule pressure, and eradicate small incipient infestations to prevent the continued expansion of invasive plants. Thus, instead of scientifically validated methods developed to limit the spread of invasive plants, managers are often left with vague suggestions for preventing the continued spread of invasive plants. We suggest that if prevention is going to be successful, researchers are going to need to conduct more applied research to provide land managers with specific prevention strategies and quantify the benefits of various prevention strategies.

AB Fibers are industrially important particles that experience coupling between rotational and translational motion during sedimentation. This leads to helical trajectories that have yet to be accurately predicted or measured. Sedimentation experiments and hydrodynamic analysis were performed on 11 copper "fibers" of average length 10.3 mm and diameter 0.20 mm. Each fiber contained three linear but non-coplanar segments. Fiber dimensions were measured by imaging their 2D projections on three planes. The fibers were sequentially released into silicone oil contained in a transparent cylinder of square cross section. Identical, synchronized cameras were mounted to a moveable platform and imaged the cylinder from orthogonal directions. The cameras were fixed in position during the time that a fiber remained in the field of view. Subsequently, the cameras were controllably moved to the next lower field of view. The trajectories of descending fibers were followed over distances up to 250 mm. Custom software was written to extract fiber orientation and trajectory from the 3D images. Fibers with similar terminal velocity often had significantly different terminal angular velocities. Both were well-predicted by theory. The radius of the helical trajectory was hard to predict when angular velocity was high, probably reflecting uncertainties in fiber shape, initial velocity, and fluid conditions associated with launch. Nevertheless, lateral excursion of fibers during sedimentation was reasonably predicted by fiber curl and asymmetry, suggesting the possibility of sorting fibers according to their shape.

TI Artificial Neural Network Models as a Decision Support Tool for
Selection in Sugarcane: A Case Study Using Seedling Populations
SO CROP SCIENCE
LA English
DT Article
ID PHENOTYPIC PATH ANALYSES; YIELD PREDICTION; IDENTIFICATION
AB Artificial neural network (ANN) models are mathematical models based on biological neural networks; they are a supervised learning method and use pattern learning from a training dataset that is a subsample of the whole dataset to produce predictions of response variables. We demonstrate the potential of an ANN model as a tool for selection in sugarcane. Cane yield components, namely stalk number, stalk height, and stalk diameter, were measured on individual seedlings and used as predictor variables to produce a selection decision (reject or select a seedling) based on an ANN model. Compared with the currently used visual method of selection, the difference in cane yield between the mean of the selected and rejected seedlings was greater for seedlings selected by the ANN model. The difference increased when similar selection intensity was applied in both selection methods. The ANN model selected fewer seedlings with cane yield lower than the population mean and rejected fewer seedlings with higher cane yield compared with the visual method. The ANN model compels the breeder to consider all traits simultaneously when deciding whether to select or reject a clone, which is likely to be more efficient than judging the merit by considering each trait independently. The ANN model can be a valuable tool to determine selection rates to be applied in selecting sugarcane families during seedling selection.

TI Complex Ploidy Level Variation in Guayule Breeding Programs

AB Guayule (Parthenium argentatum A. Gray) is a potential source of natural rubber, but attempts to domesticate and cultivate this perennial crop for large-scale production in the southwestern United States have been intermittent over the past century. Genetic improvement through modern plant breeding is needed to increase its yield potential and suitability for commercialization. Natural variation for ploidy level is extensive among individuals in wild guayule populations, but less is known about the extent of ploidy level variation in guayule breeding germplasm. Because ploidy variation is among the factors that slow the rate of genetic gain in guayule breeding programs, determining the ploidy level of publicly available guayule accessions would help to accelerate the development of stable, high yielding cultivars. To that end, we adapted flow cytometry to examine the ploidy of 34 guayule accessions available from the National Plant Germplasm System. The data revealed a natural polyploid series ranging from diploid (2n = 2x = 36) to pentaploid (2n = 5x = 90), with 4x being the predominant ploidy. Interestingly, not all plants sampled from an accession had the same ploidy level (mixed ploidy). Notably, the integration of ploidy and pedigree data uncovered complex ploidy variation in guayule breeding programs. The frequency and range of ploidy variation observed in this germplasm will help to direct future breeding efforts as well as linkage analysis and genome-wide association studies.

AB In soybean [Glycine max (L.) Merr.], mutations in genes involved in meiosis can lead to altered chromosome pairing and result in nonfunctional gametes. Mutability of the w(4) flower color locus in soybean is due to an unstable allele designated w(4)-m (mutable). Several germinal revertant studies using the w(4)-m system resulted in generation of mutants for necrotic roots, chlorophyll-deficiency, and sterility. In the present study, six male-sterile, female-sterile mutant lines were identified from an independent mutational event that involved T366H (female-partial sterile mutant), which was a germinal revertant of w(4)-m. In addition, two spontaneous mutations were identified that resulted in male-sterile, female-sterile mutants. The objectives of this study were to investigate if the newly identified six male-sterile, female-sterile germinal revertant mutants were allelic to previous germinal revertant steriles or are novel mutants and to molecularly map the locations of these six mutants along with two spontaneous male-sterile, female-sterile mutants. Three of the six mutants identified in the germinal revertant study mapped to the st8 region on chromosome Gm16 (molecular linkage group [MLG] J). The other three mutants mapped to a novel location on chromosome Gm14 (MLG B2). Of the two spontaneous mutants, one mapped to chromosome Gm02 (MLG D1b) and the second one mapped to Gm18 (MLG G).

AB Information on field management practices for seed production of newly domesticated grasses native to the southern Great Plains of North America has not been well documented. This study was conducted to document seed yield responses of one accession of plains bristlegrass [Setaria vulpiseta (Lam.) Roem. & Schult.] and three accessions of streambed bristlegrass [Setaria leucopila (Scribn. & Merr.) K. Schum.] to 0, 50, 75, 100, and 140 kg N ha(-1) yr(-1) under irrigation at Stephenville and Beeville, TX, during 2005 and 2006. The soil at Stephenville was a Windthorst fine sandy loam, mixed, thermic Udic Paleustalfs and at Beeville a Parrita clayey, mixed, active, hyperthermic, shallow Petrocalcic Paleustolls. Seed yields across N levels at Stephenville in year of establishment ranged (p < 0.05) from 57 to 753 kg ha(-1) yr(-1). October seed yield of accession 648 increased (p < 0.05) 305% with 75 kg N ha(-1) compared to the no-N treatment at Beeville. Seed production peaked at 328 kg ha(-1) for accession 648 and 352 kg ha(-1) for accession 715 in spring 2006 at Beeville. Inflorescence density was positively correlated to seed yield (from 81 to 93%). Optimum bristlegrass N fertilizer management varied with accession, location, and year.

AB Characterizing and assessing spatial distribution of soil phosphorus and herbage mass in relation to landscape properties, land use, or landscape positions is important for understanding how pasture sustainability can be managed and improved properly. Our reason for conducting this study was to determine the effects of different slope aspects and slope positions on spatial distribution of soil phosphorus and herbage mass in subtropical pastures. Soil and forage samples were collected from contiguous south-, north-, east-, and west-facing slopes across different landscape positions (top slope, middle slope, and bottom slope) in 100 ha of bahiagrass (Paspalum notatum)-based pastures from 2003 to 2006 in subtropical region of southeastern USA. Averaged across years, soils on the north-facing slope contained the greatest amount of soil phosphorus (12.4 +/- A 2.7 mg kg(-1)) when compared with other slope aspects. Slope aspect may be acting as an important topographic factor influencing local site microclimate mainly because it determines the amount of solar radiation received. The greatest herbage mass (averaged across year) of 2,967 +/- A 980 kg ha(-1) and the highest phosphorus accumulation of 7.7 +/- A 3.0 kg ha(-1) for bahiagrass were from the top slope position. There was a significant (P a parts per thousand currency sign 0.05) decrease in the average herbage mass and phosphorus accumulation with decreasing slope (top to middle slope). Between the top slope and the bottom slope, herbage mass declined from 2,967 +/- A 980 to 1,805 +/- A 370 kg ha(-1) while phosphorus accumulation was reduced by approximately 40% (7.7-4.6 kg ha(-1)). Results of our study may increase awareness on how the arrangement of food, water, and shelter and their interactions with topographic and landscape features can significantly influence the movement of animals and utilization of different pastures' resources. While our study supports our hypothesis that slope aspect and slope position could be of relative importance in controlling spatial distribution of soil phosphorus and herbage mass, broad knowledge of cattle movement in pasture situations is as critical to understanding their impact on agro-ecosystems.

AB Novel management practices are needed to increase dryland soil organic matter and crop yields that have been declining due to long-term conventional tillage with spring wheat (Triticum aestivum L.)-fallow system in the northern Great Plains, USA. The effects of tillage, crop rotation, and cultural practice were evaluated on dryland crop biomass (stems + leaves) yield, surface residue, and soil organic C (SOC) and total N (STN) at the 0-20 cm depth in a Williams loam (fine-loamy, mixed, superactive, frigid, Typic Argiustolls) from 2004 to 2007 in eastern Montana, USA. Treatments were two tillage practices [no-tillage (NT) and conventional tillage (CT)], four crop rotations [continuous spring wheat (CW), spring wheat-pea (Pisum sativum L.) (W-P), spring wheat-barley (Hordeum vulgaris L.) hay-pea (W-B-P), and spring wheat-barley hay-corn (Zea mays L.)-pea (W-B-C-P)], and two cultural practices [regular (conventional seed rates and plant spacing, conventional planting date, broadcast N fertilization, and reduced stubble height) and ecological (variable seed rates and plant spacing, delayed planting, banded N fertilization, and increased stubble height)]. Crop biomass and N content were 4 to 44% greater in W-B-C-P than in CW in 2004 and 2005 and greater in ecological than in regular cultural practice in CT. Soil surface residue amount and C and N contents were greater in NT than in CT, greater in CW, W-P, and W-B-C-P than in W-B-P, and greater in 2006 and 2007 than in 2004 and 2005. The SOC and STN concentrations at 0-5 cm were 4 to 6% greater in CW than in W-P or W-B-P in NT and CT from 2005 and 2007. In 2007, SOC content at 10-20 cm was greater in W-P and W-B-P than in W-B-C-P in CT but STN was greater in W-B-P and W-B-C-P than in CW in NT. From 2004 to 2007, SOC and STN concentrations varied at 0-5 cm but increased at 5-20 cm. Diversified crop rotation and delayed planting with higher seed rates and banded N fertilization increased the amount of crop biomass returned to the soil and surface residue C and N. Although no-tillage increased surface residue C and N, continuous nonlegume cropping increased soil C and N levels at the surface layer compared with other crop rotations. Continued return of crop residue from 2004 to 2007 may increase soil C and N levels but long-term studies are needed to better evaluate the effect of management practices on soil C and N levels under dryland cropping systems in the northern Great Plains.

AB Grassland canopy management (spring burn, mowing and residue removal in late-summer, or no management) and native tallgrass species composition (cool season mixture, warm season mixture, or combined cool and warm mixture) effects on C and N in aboveground biomass and soil were investigated at Brookings SD on a previously-plowed Barnes clay loam (fine-loamy, superactive, frigid Calcic Hapludoll). During the last 2 yr of the 9-yr experiment, shoot biomass was affected by canopy management with the burn (2,730 kg ha(-1)) and mow (3,421 kg ha(-1)) treatments containing less than no management (4,655 kg ha(-1)). Burn treatment biomass contained 1,189 kg ha(-1) and 25 kg ha(-1) of C and N, mow contained 1,433 kg ha(-1) and 33 kg ha(-1) of C and N, while no management contained 2,014 kg ha(-1) and 39 kg ha(-1) of C and N, respectively. Soil C accumulation was independent of grass species composition. Soil C accumulation rates, which increased in strong linear fashion (r (2) of 0.89 to 0.92) after initial grass establishment, were 387 kg C ha(-1) yr(-1), 503 kg C ha(-1) yr(-1), and 711 kg C ha(-1) yr(-1) for burn, mow, and no management treatments, respectively. Thus, grassland management methods used after conversion of cropland to grassland have important effects on grass biomass and soil C accumulation.

AB Prediction of soil organic C sequestration with adoption of various conservation agricultural management approaches is needed to meet the emerging market for environmental services provided by agricultural land stewardship. The soil conditioning index (SCI) is a relatively simple model used by the USDA-Natural Resources Conservation Service to predict qualitative changes in soil organic matter. Our objective was to develop a quantitative relationship between soil organic C derived from published field studies in the southeastern USA and SCI scores predicted from matching management conditions. We found that soil organic C sequestration (at 20 +/- 5 cm depth) could be reliably related to SCI across a diversity of studies in the region using the regression slope: 1.65 Mg C ha(-1) SCI(-1) [which translated into a rate of 0.25 +/- 0.04 Mg C ha(-1) yr(-1) SCI(-1) (mean +/- standard error of 31 slope estimates)]. The calibration of soil organic C on SCI scores will allow SCI to become a quantitative tool for natural resource professionals to predict soil organic C sequestration for farmers wanting to adopt conservation practices.

AB The microbiota of 84 different agricultural soils were transferred to separate samples of a 7 irradiation-sterilized field soil enriched with potato periderm, and the resulting soils were assayed for biological suppressiveness to Phytophthora erythroseptica and their effect on zoospore production. The 13 most suppressive soil samples, which reduced zoospore production by 14 to 93% and disease severity on tubers by 6 to 21%, were used to isolate 279 organisms. Fourteen strains that reduce pink rot infections in preliminary tests were selected for further study. Six bacterial strains that reduced the severity of disease (P <= 0.05, Fischer's protected least significant difference) in subsequent tests were identified as Bacillus simplex (three strains), Pantoea agglomerans, Pseudomonas koreensis, and P. lini. Relative performance indices (RPIs) for biocontrol efficacy and for each of four kinetic parameters, including total colony-forming units (CFU(max)), biomass production values (DW(max)), cell production after 8 h (OD(8)), and time of recovery from oxygen depletion (DT) were calculated for each strain. Overall RPI(Eff,Kin) values for each strain then were calculated using strain RPI values for both efficacy (RPI(Eff)) and kinetics (RPI(Kin)). Strains with the highest RPIEff,K; possess the best biocontrol efficacy of the strains tested and liquid culture growth characteristics that suggest commercial development potential.

AB Soybean rust, caused by Phakopsora pachyrhizi, is an important foliar disease of soybean. Disease severity is dependent on several environmental factors, although the precise nature of most of these factors under field conditions is not known. To help understand the environmental factors that affect disease development, soybean rust epidemics were studied in Nigeria by sequentially planting an early-maturing, highly susceptible cultivar, TGx 1485-1D, and a late-maturing, moderately susceptible cultivar, TGx 1448-2E, at 30- to 45-day intervals from August 2004 to September 2006. Within each planting date, disease onset occurred earlier on TGx 1485-1D than on TGx 1448-2E, and rust onset was at least 20 days earlier on soybean planted between August and October than on soybean planted between November and April. The logistic model provided a better description of the temporal increase in rust severity than the Gompertz model. Based on the logistic model, the highest absolute rates of disease increase were observed on soybean planted in September 2006 and October 2004 for TGx 1485-1D and TGx 1448-2E, respectively. Disease severity as measured by the relative area under disease progress curve (RAUDPC) was significantly (P < 0.05) negatively correlated with evaporation (r = -0.73), solar radiation (r = -0.59), and temperature (r = -0.64) but positively correlated with urediniospore concentration (r = 0.58). Planting date and soybean cultivar significantly (P < 0.05) affected disease severity, with severity being higher on soybean crops planted during the wet season than those planted in the dry season. Within the wet season, planting in May and July resulted in a significantly (P < 0.05) lower RAUDPC than planting between August and October. Yields were significantly (P < 0.001) related to RAUDPC during the wet season, whereby an increase in RAUDPC resulted in a linear decrease in yield. This study suggests that selection of planting date could be a useful cultural practice for reducing soybean rust.

AB Biomass is the largest source of renewable energy in the United States, and corn ethanol currently constitutes the vast majority of the country's biofuel. Extended plantation of annual crops for biofuel production, however, has raised concerns about long-term environmental, ecological, and socioeconomic consequences. Switchgrass (Panicum virgatum L.), along with other warm-season grasses, is native to the precolonial tallgrass prairie in North America and is identified as an alternative energy crop for cellulosic feedstocks. This article describes a phenology-based geospatial approach to mapping the geographic distribution of this perennial energy crop in the tallgrass prairie. Time series of Moderate Resolution Imaging Spectroradiometer (MODIS) satellite imagery (500-m resolution, eight-day interval) in 2007 were processed to extract five phenology metrics: end of season, season length, peak season, summer dry-down, and cumulative growth. A multitier decision tree was developed to map major crops, especially native prairie grasses in the region. The geographic context of the 20 million ha of perennial native grasses extracted in this study could be combined with economic and environmental considerations in a geographic information system to assist decision making for energy crop development in the prairie region.

AB The role of land-atmosphere interactions under heterogeneous surface conditions is investigated in order to identify mechanisms responsible for altering surface heat and moisture fluxes. Twelve coupled land surface large eddy simulation scenarios with four different length scales of surface variability under three different horizontal wind speeds are used in the analysis. The base case uses Landsat ETM imagery over the Cloud Land Surface Interaction Campaign (CLASIC) field site for 3 June 2007. Using wavelets, the surface fields are band-pass filtered in order to maintain the spatial mean and variances to length scales of 200 m, 1600 m. and 12.8 km as lower boundary conditions to the model (approximately 0.25, 1.2 and 9.5 times boundary layer height). The simulations exhibit little variation in net radiation. Rather, there is a pronounced change in the partitioning of the surface energy between sensible and latent heat flux. The sensible heat flux is dominant for intermediate surface length scales. For smaller and larger scales of surface heterogeneity, which can be viewed as being more homogeneous. the latent heat flux becomes increasingly important. The simulations showed approximately 50 Wm(-2) difference in the spatially averaged latent heat flux. The results reflect a general decrease of the Bowen ratio as the surface conditions transition from heterogeneous to homogeneous. Air temperature is less sensitive to variations in surface heterogeneity than water vapor, which implies that the role of surface heterogeneity may be to maximize convective heat fluxes through modifying and maintaining local temperature gradients. More homogeneous surface conditions (i.e. smaller length scales), on the other hand, tend to maximize latent heat flux. The intermediate scale (1600 m) this does not hold, and is a more complicated interaction of scales. Scalar vertical profiles respond predictably to the partitioning of surface energy. Fourier spectra of the vertical wind speed, air temperature and specific humidity ((w) over tilde, (T) over tilde and (q) over tilde) and associated cospectra ((w) over tilde(T) over tilde, (w) over tilde(q) over tilde and (T) over tilde(q) over tilde), however, are insensitive to the length scale of surface heterogeneity, but the near surface spectra are sensitive to the mean wind speed.

AB 1. A valuable technique in the study of insect movement is protein marking, a quantitative method where individuals are categorized as marked or unmarked based on the amount of foreign protein detected by an enzyme-linked immunosorbent assay (ELISA).
2. Whether individuals are considered marked or not is dependent on a threshold value chosen by the experimenter. The traditional method of choosing the threshold accepts some risk of false positives, wherein unmarked individuals are misclassified as marked. The error rate associated with this method, adopted from the rubidium marking literature, relies on assumptions violated by most ELISA data.
3. We critically examined the effect of violating these assumptions on the false positive rate. In long-distance dispersal studies where the ratio of unmarked to marked insects is high, false positives can seriously bias estimates of insect movement abilities.
4. Simulations demonstrated that the conventional method for choosing a threshold (i) masks the presence of false positives, (ii) results in a 10-fold higher than expected false positive rate, and (iii) relies on assumptions of normality that are rarely satisfied; non-normality produces further increases in false positive rates.
5. We provide some solutions by introducing a new procedure for choosing a threshold that decreases the incidence of false positives and allows data to be corrected for anticipated rates of false positives. This methodology should enhance researcher confidence in the data generated from dispersal studies using protein marking techniques.

AB Forest carbon sinks significantly contribute to mitigation of atmospheric concentrations of carbon dioxide. Thus, estimating forest carbon is becoming important to develop policies for mitigating climate change and trading carbon credits. However, a great challenge is how to quantify uncertainties in estimation of forest carbon. This study investigated uncertainties of mapping aboveground forest carbon due to location errors of sample plots for Lin-An County of China. National forest inventory plot data and Landsat TM images were combined using co-simulation algorithm. The findings show that randomly perturbing plot locations within 10 distance intervals statistically did not result in biased population mean predictions of aboveground forest carbon at a significant level of 0.05, but increased root mean square errors of the maps. The perturbations weakened spatial autocorrelation of aboveground forest carbon and its correlation with spectral variables. The perturbed distances of 800 m or less did not obviously change the spatial distribution of predicted values. However, when the perturbed distances were 1600 m or larger, the correlation coefficients of the predicted values from the perturbed locations with those from the true plot locations statistically did not significantly differ from zero at a level of 0.05 and the spatial distributions became random.

AB Combustion of coal produces over half of the electricity used in the United States and generates 123.5 m mt year (1) of coal combustion products (CCPs). Only about 45% of CCPs are beneficially utilized and the rest are discarded, mainly in landfills. One class of CCPs, called flue gas desulfurization (FGD) products, generated by removal of SO(2) from the exhaust gas of power plants, has physical and chemical properties that make them suitable for beneficial uses in agriculture. FGDs can be used as a soil amendment to provide a nutrient source for crops; ameliorate acidic soils; remediate sodic soils; improve soil structure to increase infiltration and water storage; reduce soil erosion and movement of sediments, nutrients, and pesticides to surface water; and stabilize and enrich organic composts and manures. FGD gypsum produced by a forced oxidation step following wet scrubbing of SO2, is the most promising of the FGD materials for agricultural uses. FGD gypsum is comparable to commercially available mined gypsum. When applied to soil at agronomic rates, FGD gypsum appears to pose little environmental risk. However, more information is needed on risks associated with the introduction of trace elements such as Hg and As to the environment. Management practices for specific uses of FGDs also need to be developed across a range of soils, cropping systems, and climate regimes.

AB Rice (Oryza sativa L.) is a globally important cereal plant, and as a primary source of food it accounts for 35-75% of the calorie intake of more than 3 billion humans. With the likely growth of world's population toward 10 billion by 2050, the demand for rice will grow faster than for other crops. There are already many challenges to achieving higher productivity of rice. In the future, the new challenges will include climate change and its consequences. The expected climate change includes the rise in the global average surface air temperature. At the end of the twenty-first century, the increases in surface air temperature. At the end of the twenty-first century, the increases in surface air temperature will probably be around 1.4-5.8 degrees C, relative to the temperatures of 1980-1999, and with an increase in variability around this mean. Most of the rice is currently cultivated in regions where temperatures are above the optimal for growth (28/22 degrees C). Any further increase in mean temperature or episodes of high temperatures during sensitive stages may reduce rice yields drastically. In tropical environments, high temperature is already one of the major environmental stresses limiting rice productivity, with relatively higher temperatures causing reductions in grain weight and quality. Developing high-temperature stress-tolerant rice cultivars has become a proposed alternative, but requires a thorough understanding of genetics, biochemical, and physiological processes for identifying and selecting traits, and enhancing tolerance mechanisms in rice cultivars. The effects of high-temperature stress on the continuum of soil-rice plant-atmosphere for different ecologies (with or without submerged conditions) also need detailed investigations. Most agronomic interventions for the management of high-temperature stress aim at early sowing of rice cultivars or selection of early maturing cultivars to avoid high temperatures during grain filling. But these measures may not be adequate as high-temperature stress events are becoming more frequent and severe in the future climate. In this review, the effects of high-temperature stress on rice growth, yield, and quality characters, including various morphological, physiological, and biochemical mechanisms along with the possible use of conventional and molecular breeding methods, and crop growth simulation models and techniques are discussed. The mitigation and adaptation strategies for dealing with high-temperature stress in rice are highlighted. We conclude that there are considerable risks for rice production, stemming from high-temperature stress but benefits from the mitigation or adaptation options through progress in rice research may sustain the production systems of rice in the future warmer world.

AB The need for accurate and rapid field identification of wood to combat illegal logging around the world is outpacing the ability to train personnel to perform this task. Despite increased interest in non-anatomical (DNA, spectroscopic, chemical) methods for wood identification, anatomical characteristics are the least labile data that can be extracted from solid wood products, independent of wood processing (sawing, drying, microbial attack). Wood identification using anatomical characteristics is thus still a viable approach to the wood identification problem, and automating the process of identification is an attractive and plausible solution. The undisputed increase of computer power and image acquisition capabilities, along with the decrease of associated costs, suggests that it is time to move toward non-human based automated wood identification systems and methods. This article briefly reviews the foundations of image acquisition and processing in machine vision systems and overviews how machine vision can be applied to wood identification.

AB Variation in the size and overlap of space use by white-tailed deer (Odocoileus virginianus) has broad implications for managing deer-human conflicts and disease spread and transmission in urban landscapes. Understanding which factors affect overlap of home range by various segments (i.e., age, sex) of an urban deer population has implications to direct contact between deer on disease epidemiology. We assessed size of home range and overlap of space use using the volume of intersection index (VI) for deer in an urban landscape by sex, age, season, and time of day. We found mean space use was larger for males than for females, for males,3 years old than for males >= 3 years old, and during nocturnal hours compared with diurnal hours. We also identified larger space use by both sexes during the nongrowing than the growing season. Overlap of space use for female and male deer in our urban landscape differed considerably depending on demographic (i.e., age) and environmental variables (i.e., time, season). For example, highest mean VIs occurred between 6-year-old females (mean = 0.51 +/- 0.10) and 5- and 6-year-old males (mean = 0.49 +/- 0.14); no mean VI was greater than 0.31 between females and males for any age combination. Variation in overlap of space use for urban deer provides new information for managing deer-human conflicts and direct transmission of disease between various segments of a deer population in an urban landscape.

AB Recent literature suggests that natural disasters such as wildfires often have the short-term effect of obringing people togethero while also under some circumstances generating social conflict at the local level. Conflict has been documented particularly when social relations are disembedded by nonlocal entities and there is a perceived loss of local agency. There is less agreement about longer term impacts. We present results of a re-study of a set of communities affected by the largest wildfire in Arizona history. The re-study uses structuration theory to suggest that while local recovery has been generally very successful, vestiges of both fire-related social cohesion and conflict have survived. While some sources of post-fire conflict and cohesion have remained relatively unchanged, others have evolved. We suggest that more needs to be known about the longer term effects of large wildfire events and the role that advanced preparation for such events plays in local recovery.

AB Non point-source pollution of fresh waters by agricultural phosphorus (P) can accelerate eutrophication of surface waters and limit their use for drinking, recreation, and industry. An important pathway of agricultural P transport is surface runoff, to which unincorporated dung from grazing cattle can be a significant contributor. Computer models commonly used to identify agricultural areas with a high potential for P export do not adequately simulate dung application to the soil surface, dung disappearance, and dung P loss to runoff. We developed a new model to simulate these processes for grazing cattle dung. The model simulates dung organic matter decomposition and assimilation into soil by bioturbation as a function of air temperature and dung moisture. We validated that the model can accurately predict rates of dung disappearance, using data from 12 published studies. The model also simulates four pools of inorganic and organic P, P mineralisation to water-extractable P, leaching of dung water-extractable P into soil by rain, and loss of dissolved inorganic P in runoff. We validated the ability of the model to reliably simulate these P processes, using data from six published dung P transformation studies and six runoff studies. Overall, the model represents a novel approach for assessing the environmental impact of grazing dairy and beef cattle. Research should investigate the impact of dung deposition rate as a function of time and animal diet and type, where deposition occurs relative to runoff movement, weather conditions, and the ability of dung pad crusting to reduce P release to runoff.

AB Introduction Atmospheric deposition is an important input of major nutrients into forest ecosystems. The long-term goal of this work was to apply stable isotope methodology to assess atmospheric nutrient deposition in forest systems.
Materials and methods A labelling experiment of foliage with stable isotopes of primary and secondary macro nutrients (N-15, Mg-26 and Ca-42 injected into the stem sapwood) was carried on standing trees to monitor interactions between canopy and precipitations. N-15 rapidly reached the foliage; however, Mg and Ca were not detected in foliage until more than a year after injection.
Results and discussion The delay in mobilization of Mg and Ca prevented us from accurately modelling deposition contributions of these two elements. Nonetheless, an upscaling approach based on published results on Ca transport in shoots xylem was used to simulate our results. These simulations of Ca transport at the tree scale were consistent with our experimental data.
Conclusion This consistency suggested that mechanisms of nutrient transport are the same at the different scales. Nitrogen was rapidly transported in the xylem to foliage, probably mainly by mass flow. Conversely, transport of Mg and particularly Ca was considerably delayed, probably due to successive cation exchanges along the xylem vessels.

AB Ten polymorphic microsatellite loci from the fungus Puccinia emaculata, responsible for rust disease of switchgrass (Panicum virgatum) were developed. Loci were characterized using 20 single-pustule derived isolates of P. emaculata collected from switchgrass plants growing in the southeastern US. The number of alleles per locus ranged from 2 to 5. Observed heterozygosity ranged from 0 to 0.89 and expected heterozygosity ranged from 0.21 to 0.77. These microsatellite loci provide a sufficient set of markers to perform genetic diversity and epidemiological studies of P. emaculata.

AB This study demonstrates the feasibility of integrating the production of nano-fibrillated cellulose (NFC), a potentially highly valuable biomaterial, with sugar/biofuel (ethanol) from wood fibers. Commercial cellulase enzymes were used to fractionate the less recalcitrant amorphous cellulose from a bleached Kraft eucalyptus pulp, resulting in a highly crystalline and recalcitrant cellulose (RC). The RC is difficult to hydrolyze to sugars but very suitable for producing biobased nanomaterials through mechanical homogenization. A range of fractionation yields of RC from 10-70% can be achieved by varying fractionation duration and enzyme dosage. The crystallinity of the RC was found to be as much as 24% higher than that of the original bleached pulp. The cellulase fractionation process facilitated mechanical homogenization by significantly reducing the degree of polymerization (DP) to about 400 and the length of the fibers to about 200 mm. The hydrolyzed sugars were found to be easily converted to ethanol through yeast fermentation with excellent efficiency of 92%. Films made from nano-fibrillated cellulose were found to be optically transparent, with opacity as low as 12%. The NFC films were mechanically strong and stiff, with tensile strengths and moduli approximately 10 and 6 times higher than film made from fibers that had not been nano-fibrillated.

AB Interdisciplinary teamwork has become a foundation of natural resources planning and management in the US. Yet, we know little about the degree of interdisciplinary collaboration of natural resource planning teams. We conducted 10 case studies of Forest Service NEPA (National Environmental Policy Act) teams working on projects related to the 2005 Travel Management Rule. Although teams' critical tasks were similar, we found wide variation in interdisciplinary teamwork approaches. We propose three typologies of teamwork processes and discuss relationships between teams' work approaches and process outcomes. Rather than being easily labelled as holistically 'collaborative' or 'non-collaborative', teams may more typically move in and out of different modes of collaboration (or non-collaboration) throughout the different stages of teamwork processes. Results suggest that greater external pressure may lead teams to adopt a more internally collaborative approach and that empowering leadership styles may enhance the success of more collaborative approaches in terms of perceived outcomes. Future research on the relationships between extra-team context, team collaboration, and leadership styles may provide insight into the drivers of outcomes in natural resource planning teams.

DE Urban trees; Tree benefits; Real estate value; Urban forest evaluation
AB It is well known that urban trees produce various types of benefits and costs. The computer tool i-Tree STRATUM helps quantify tree structure and function, as well as the value of some of these tree services in different municipalities. This study describes one of the first applications of STRATUM outside the U.S. Lisbon's street trees are dominated by Celtis australis L, Tilia spp., and Jacaranda mimosifolia D. Don, which together account for 40% of the 41,247 trees. These trees provide services valued at $8.4 million annually, while $1.9 million is spent in their maintenance. For every $1 invested in tree management, residents receive $4.48 in benefits. The value of energy savings ($6.20/tree), CO2 reduction ($0.33/tree) and air pollutant deposition ($5.40/tree) were comparable to several other U.S. cities. The large values associated with stormwater runoff reduction ($47.80/tree) and increased real estate value ($144.70/tree) were substantially greater than values obtained in U.S. cities. Unique aspects of Lisbon's urban morphology and improvement programs are partially responsible for these differences. (C) 2011 Elsevier GmbH. All rights reserved.

AB Old World climbing fern, Lygodium microphyllum, is one of the most serious invasive weeds impacting south Florida and development of biological control is crucial for sustainable management. Larvae of a small moth, Austromusotima camptozonale, were discovered defoliating L. microphyllum in Australia. Preliminary testing suggested this moth was a Lygodium specialist. Laboratory host range testing was conducted on 65 species of test plants, from 31 families, comprising seven Lygodium species, four close relatives, 45 other species of ferns and fern allies, eight agricultural crops and one gymnosperm species plus the primary host L. microphyllum. Significant oviposition occurred only on other species of Lygodium. No eggs were laid on the agricultural crops, or about half the species of non-Lygodium ferns and fern allies tested. Oviposition on the other non-Lygodium ferns was very low, except on Anemia adiantifolia and Blechnum serrulatum, which received modest egg loads, but did not support development to adult. Larval feeding was low to non-existent on all the non-Lygodium species. Larvae developed to adult only on the native, American climbing fern L. palmatum, and to a lesser extent on L. japonicum. Lygodium japonicum is a naturalized invasive weed in the United States. Colonies of A. camptozonale were unable to persist on L. palmatum and died out in two to seven generations. Freezing winter temperatures in states where L. palmatum occurs would be lethal to A. camptozonale. It was concluded that A. camptozonale would pose no threat to native or cultivated plants in North America or the Caribbean and should be considered as a weed biological control agent against L. microphyllum.

AB Ammonia (NH3) volatilization is the major pathway for mineral nitrogen (N) loss from N sources applied to soils. The information on NH3 volatilization from slow-release N fertilizers is limited. Ammonia volatilization, over a 78-d period, from four slow-release N fertilizers with different proportions of urea and urea polymer [Nitamin 30L (liquid) (L30), Nitamin RUAG 521G30 (liquid) (G30), Nitamin 42G (granular) (N42), and Nitroform (granular) (NF)] applied to a sandy loamy soil was evaluated. An increase in temperature from 20 to 30 degrees C increased cumulative NH3 volatilization loss in the sandy soil by 1.4-, 1.7-, and 1.8-fold for N42, L30, and G30, respectively. Increasing the proportion of urea in the slow-release fertilizer increased NH3 volatilization loss. At 30 degrees C, the cumulative NH3 volatilization over 78 d from a sandy soil accounted for 45.6%, 43.9%, 22.4%, and 1% of total N applied as N42, L30, G30, and NF, respectively. The corresponding losses in a loamy soil were 9.2%, 3.1%, and 1.7%. There was a significantly positive correlation between NH3 volatilization rate and concentration of NH4-N released from all fertilizers, except for NF (n = 132; r = 0.359, P = 0.017 for N42; r = 0.410, P = 0.006 for L30; and r = 0.377, P 0.012 for G30). Lower cumulative NH3 volatilization from a loamy soil as compared to that from a sandy soil appeared to be related to rapid nitrification of NH4-N in the former soil than that in the latter soil. These results indicate the composition of slow-release fertilizer, soil temperature, and soil type are main factors to dominate NH3 volatilization from slow- release fertilizers.

AB Roxarsone is used in the poultry and swine industries as a feed additive to treat coccidiosis and other intestinal disorders as well as to improve feed efficiencies and weight gain. 3-Amino-4-hydroxyphenylarsonic acid (AHPA) was conjugated with keyhole limpet hemocyanin in the presence of bis-sulfosuccinimidyl-suberate for the immunogen in rabbits. The antibody has minor cross-reactivity towards 2-aminophenylarsonic acid (7.3%, n = 3), arsanilic acid (5.3%, n = 3), AHPA (4%, n = 3), and phenylarsonic acid (3%, n = 3). The mean IC(50)s for PBST, muscle 1:10, and muscle 1:20 were 11.7 +/- 1.50, 13.1 +/- 2.53 and 12.0 +/- 2.45 ng/mL (n = 6). Using a standard curve prepared in chicken muscle extract and diluted with PBST at 1:20, muscle samples spiked with roxarsone at 2.5, 5, 10 and 25 ng/mL had recoveries of 117%, 98%, 80% and 65% having coefficients of variation of 36, 9.2, 10.2 and 11.5 respectively (n = 6).

AB To advance the understanding of delignification with polyoxometalates (POMs) that have been explored for use in bleaching of chemical pulps, the transformation of lignin during anaerobic treatment of birch kraft pulp with an equilibrated POM mixture composed of Na(5(+2))[SiV(1(-0.1))MoW(10(+0.1))O(40)] was investigated. The conversion factor between the Klason lignin and the kappa number corrected for the hexenuronic acid (HexA) contribution gradually increased, indicating loss of lignin oxidizability. Comparative analysis of residual lignins isolated from pulps of decreasing kappa number showed that lignin undergoes changes that include a sharp reduction in the content of PhOH groups, a gradual demethylation, and a high increase in carbonyl groups. The results indicated that the POM treatment of kraft pulps leads to the loss of aromaticity, most likely caused by the conversion of aromatic rings to quinone moieties. The 2D NMR studies revealed the disappearance of the correlations assigned to stilbene structures formed during kraft pulping, and the weakening of those assigned to the native lignin bonds. The GPC studies showed a gradual lignin depolymerization.

AB Whole-canopy net CO2 exchange (NCEC) was measured near key stages of fruit development in grapevines (Vitis vinifera L. cv. Cabernet Sauvignon) that were managed under three approaches to regulated deficit irrigation (RDI): (1) standard practice (RDIS), or weekly replacement of 60-70% of estimated evapotranspiration for well watered grapevines; (2) early additional deficit (RDIE), or one-half of RDIS applied between fruit set and the onset of ripening (veraison), followed by RDIS; and (3) RDIS followed by late additional deficit (RDIL), or one-half of RDIS applied between veraison and harvest. Summed between fruit set and harvest, nearly 40% less irrigation was applied to RDIE vines and similar to 20% less to RDIL vines than to those continuously under RDIS. After similar to 5 weeks of additional deficit, NCEC in RDIE vines was 43-46% less per day than in RDIS vines. After RDIL vines had been under additional water deficit for similar to 3 weeks, NCEC was similar to 33% less per day than in RDIS vines. Instantaneous rates of NCEC responded rapidly to irrigation delivery and elapsed time between irrigation sets. Concurrent single-leaf measurements (NCEL) reflected the relative differences in NCEC between irrigation treatments, and were linearly associated with NCEC (r(2) = 0.61). Despite halving the water applied under commercial RDI, mid-day stomatal conductance values in RDIE and RDIL of similar to 50-125 mmol m(-2) s(-1) indicated that the additional deficit imposed only moderate water stress. There was no effect of additional deficit on yield or berry maturity.

AB Forests in the United States generate many non-market benefits for society that can be enhanced and diminished by wildfire and wildfire management. The Federal Wildland Fire Management Policy (1995, updated 2001), and subsequent Guidance to the Implementation of that policy provided in 2009, require fire management priorities be set on the basis of values to be protected (including natural and cultural resources), costs of protection, and natural resource management objectives (including beneficial fire effects). Implementation of this policy is challenging because those charged with executing the policy have limited information about the value that society places on non-market goods and services at risk. This paper reviews the challenges of accommodating non-market values affected by wildfire in social cost-benefit analysis and proposes an economic research agendum to support more efficient management of wildfire in the United States.

AB Wildland fires and resulting effects have increased in recent years. Efforts are under way nationwide to proactively manage vegetative conditions to reduce the threat of wildland fires. Public support is critical to the successful implementation of fuels reduction programs, particularly at the wildland-urban interface. This study examines public acceptance of fuels treatments and influencing factors in five neighbourhoods in Oregon and Utah located adjacent to public lands. Support for treatment use was high across locations. Findings suggest citizen trust in agency managers to successfully implement treatment activities is particularly influential on treatment acceptance. Thus, building and maintaining trust with local citizens is an essential element in the successful implementation of fuel management programs.

AB The Healthy Forests Restoration Act of 2003 (HFRA) encourages communities to develop community wildfire protection plans (CWPPs) to reduce their wildland fire risk and promote healthier forested ecosystems. Communities who have developed CWPPs have done so using many different processes, resulting in plans with varied form and content. We analysed data from 13 case-study communities to illustrate how the characteristics of HFRA have encouraged communities to develop CWPPs that reflect their local social and ecological contexts. A framework for analysing policy implementation suggests that some elements of HFRA could have made CWPP development and implementation problematic, but these potential shortcomings in the statute have provided communities the freedom to develop CWPPs that are relevant to their conditions and allowed for the development of capacities that communities are using to move forward in several areas.

AB Determining age in crustaceans is inherently imprecise because they molt periodically and do not retain hard structures throughout their lifespan. Morphological measurements are often used to estimate age, but variability in individual growth rate and molt frequency can result in a wide distribution of sizes in a single age class, making size a poor predictor of true age. Concentration of the autofluorescent age pigment, lipofuscin, has been shown to be directly related to actual age in many crustaceans. The present study assessed the potential of using extractable lipofuscin as a method for determining age in the ghost shrimp Neotrypaea californiensis. Following validation of the technique, lipofuscin-based aging was used to determine age structures for 3 populations of N. californiensis, and these were compared to age structures determined using traditional length-based methods. Analysis of lipofuscin revealed up to 13 age classes where the size-based analysis showed only 7. Comparison of mean size-at-age among populations in Oregon and Washington estuaries demonstrated that growth rate varied spatially, probably responding to site-specific environmental factors like food availability and population density. N. californiensis negatively impact oyster aquaculture in Pacific Northwest estuaries. Analysis of extractable lipofuscin proved to be a more accurate method of age determination than body-length measurements and should facilitate more in-depth investigations of basic biological and ecological processes, which will benefit current efforts to develop an integrated pest management plan for N. californiensis.

AB Tilapias have been shown to have a dietary requirement for linoleic (n-6) series fatty acids (FAs; 18:2[n-6] or 20:4[n-6]). The optimum dietary levels of n-6 previously reported were 0.5% for redbelly tilapia Tilapia zillii and 1.0% for Nile tilapia Oreochromis niloticus. Tilapias may also have a requirement for the linolenic (n-3) FA series (18:3[n-3], 20:5[n-3], or 22:6[n-3]), but the optimum dietary requirement levels for n-3 in various tilapia species have not been determined. The presence of high levels of either n-6 or n-3 may spare the requirement of the other, although n-6 appears to have a better growth-promoting effect than n-3. Tilapias possess the ability to desaturate and chain elongate 18:2(n-6) to 20:4(n-6) and 18:3(n-3) to 20:5(n-3) and 22:6(n-3). Plant oils that are rich in n-6, n-3, or both FA series (e.g., soybean oil, corn oil, sunflower oil, palm oil products, and linseed oil) have been reported to be good lipid sources for tilapia. Beef tallow and pork lard are poorly utilized by tilapia. However, these lipids can be used in combination with other lipid sources provided that the essential FA requirements are met. Information on the nutritional value of fish oil for tilapias is inconsistent. Some studies have shown that the nutritional value of fish oil is similar to that of plant oils, while others have reported poor performance of diets that contain fish oil. Fish oil provided good spawning performance for tilapia broodstock reared in brackish water, whereas soybean oil yielded good reproductive performance in freshwater. The sparing effect of dietary lipids on protein utilization has also been demonstrated. However, tilapias do not tolerate as high a dietary lipid level as do salmonids. A dietary lipid level of 5-12% has been suggested as optimum in diets for tilapias.

AB Water-extractable phosphorus (WEP) in manures can influence the risk of phosphorus (P) losses in runoff when manures are land applied. We evaluated several manure handling and extraction variables to develop an extraction procedure for WEP that will minimize pre-analysis manure-sample-handling effects on WEP measurements. We also related manure WEP determinations to runoff dissolved reactive phosphorus (DRP) concentrations found in previously conducted field simulated rainfall experiments using the same manures to evaluate WEP as a predictor of P runoff losses. Dairy and poultry manure WEP concentrations increased with manure-to-water extraction ratio and shaking time. Relative to fresh manures, drying and grinding dairy manures before analysis usually decreased WEP concentrations, while WEP in poultry manures was often increased. Pre-analysis handling effects on WEP were minimized at the 1: 1000 extraction ratio with a 1-h shaking time. Relationships between manure WEP and runoff DRP concentrations were strongly influenced by season of year and WEP extraction procedure. The best prediction of DRP concentration in spring runoff experiments was with manure WEP concentration at the 1: 1000 extraction ratio. With fall runoff studies, DRP concentrations were best predicted with WEP application rate rather than concentration. These seasonal differences can be explained by the greater percentage of rainfall that ran off in the fall compared to the spring. For all studies, runoff DRP concentrations were strongly related (r(2) = 0.82) to the ratio of runoff to rainfall volumes, confirming that models need to take runoff hydrology into account as well as manure WEP in P-loss risk assessments.

The nutrient deficiency treatments were induced with a complete nutrient formula minus one of the nutrients. Boron toxicity was also induced by increasing the element ten times higher than the complete nutrient formula. Reagent grade chemicals and deionized water of 18-mega ohms purity were used to formulate treatment solutions. The plants were automatically irrigated and the solution drained from the bottom of the pot and captured for reuse. The nutrient solutions were completely replaced weekly. Plants were monitored daily to document and photograph sequential series of symptoms as they developed. Typical symptomology of nutrient disorders and critical tissue concentrations are presented. Plants were harvested for nutrient analysis when initial symptoms were expressed. Nutrient deficiency symptoms were described and foliar nutrient concentrations provided.

ID ANTIMYCIN
AB Aquaculturists have often suffered predation losses in the production of freshwater giant river prawn Macro-brachium rosenbergii due to the presence of wild fish species in culture ponds. The piscicide rotenone is widely used to remove undesirable fish species from ponds. Although evidence in the technical literature suggests that crustaceans generally have a higher tolerance to rotenone than fish, there are currently no data on the acute or chronic toxicity of rotenone to juvenile freshwater prawns. In this study, two static acute-toxicity bioassays (96 h) were conducted using Prentox Prenfish (5% active ingredient) rotenone to determine the median lethal concentration (LC50) for juvenile freshwater prawns (average weight = 0.55 g, SD = 0.25; length = 41.43 mm, SD = 6.45). In bioassay 1, prawns were exposed to rotenone concentrations of 1.0, 3.0, 5.0, and 10.0 mg/L. In bioassay 2, prawns were exposed to rotenone concentrations of 2.2, 3.6, 6.0, 10.0, and 16.7 mg/L. All rotenone concentrations used in the study were based on the total product of the commercial rotenone formulation. The LC50 calculated in bioassay 1 was 6.2 mg/L, and the LC50 calculated in bioassay 2 was 7.5 mg/L. Freshwater prawns were able to tolerate 3.0 to 3.6 mg/L of rotenone with no mortality or apparent adverse effects during the study. Prawns held at the end of each bioassay for 5 d showed no signs of delayed effects from rotenone exposure. Data from this study indicate that juvenile prawns should be able to tolerate the concentrations of rotenone required to eradicate certain problematic wild fish species.

AB The European grape vine moth, Lobesia botrana ([Denis and Schiffermuller]), is one of the most destructive pests of grape in the Palearctic Region. Larvae feed on fruit, causing direct damage and promoting secondary infection by Botrytis cinerea Persoon (botrytis bunch rot or gray mold). On September 30, 2009, tortricid larvae damaging grapes in the Napa Valley of California were identified as L. botrana, representing the first records of this species in North America. The presence of L. botrana could have a significant impact on California agriculture-wine, table, and raisin grapes are grown on more than 800,000 acres throughout the state. We provide descriptions and illustrations to aid in the identification of this newly arrived pest, along with a brief history of its discovery.

AB A new species of leafmining fly in the genus Phytomyza Fallen (Diptera: Agromyzidae) is reared from Gelsemium Juss, representing the first known instance of an agromyzid feeding on a host plant in Gelsemiaceae (Asteridae). The host plant, likely G. sempervirens (L.) (the "evening trumpetflower"), but possibly also G. rankinii Small, is a perennial vining species native to the southeastern United States. All examined specimens of this leafminer were reared from leaves collected in North Carolina from January to April in 1996 and 1997. The morphology and life history of the new species, Phytomyza omlandi Scheffer and Lonsdale, are discussed; photographs and illustrations are provided for external structures, the male genitalia and the leafmine. Morphological and molecular data support a close phylogenetic relationship between this species and the holly leafmining P. ilicis Curtis complex, although exact relationships are still uncertain and studies are ongoing.

AB Aiming to determine if there is genetic differentiation among Pious patula Schiede et Chamizo populations along an attitudinal gradient and for quantifying the genotype x environment interaction, 13 Pious patula populations were sampled from forests of the Native Indian Community of Ixtlan de Juarez, Oaxaca, state of Mexico, along an attitudinal gradient (2400 m to 3000 m), cones being collected on groups of trees on every 50 m of attitudinal step). Seedlings were grown in tree pots in two different environments: a shadehouse located at Ixtlan de Juarez, and in a greenhouse and then in a shadehouse situated at Quebec, Canada. Total seedling height was measured at 6-months of age in both locations. Results indicated that populations differed significantly (P = 0.025), but there was no significant genotype x environment interaction (P = 0.426; B type genetic correlation = 0.93). Population from 2650 m (middle altitude) exhibited the best height. Although not definitive, our study suggests the presence of a weak attitudinal pattern of variation in seedling height, where populations originating of mid-altitudes exhibit the highest growth potential while populations from the upper and lower attitudinal extremes exhibit the lowest growth potential.

AB Rhizoctonia solani is an important plant pathogen for a number of crops and maintaining an extensive collection of reference isolates is important in understanding relationships of this pathogen with multiple hosts. Current long-term storage methods typically call for frequent transfer increasing the risk of changes in morphological, physiological or virulence characteristics. Cryopreservation using storage in liquid nitrogen (LN) was evaluated to examine the potential for storage of a R. solani culture collection containing 106 isolates (primarily from sugar beet). Cultures were stored on autoclaved barley grains in the vapour phase of LN. After 60 days, 5 years and 10 years in storage, all isolates were tested for viability by calculating the percentage of barley grains from which R. solani mycelia grew. Five years after initial storage, all isolates except one had no change in viability. After 10 years in storage, 67 of 106 isolates had no significant decrease in viability, 39 of 106 isolates had a significant decrease in viability but only 9 isolates had less than 10% growth, with 4 having no growth. A subset of isolates stored for 10 years were tested for pathogenicity on a susceptible (FC901) and resistant (FC703) sugar beet germplasm. All isolates tested maintained approximately the same level of virulence that they had prior to storage on both germplasms. This indicates that cryogenic methods are suitable for the preservation or storage of R. solani culture collections, although efficacy may vary with individual isolates.

AB An azalea little leaf (AzLL) disease characterised by abnormally small leaves, yellowing and witches'-broom growth symptoms was observed in suburban Kunming, southwest China. Transmission electron microscopic observations of single-membrane-bound, ovoid to spherical bodies in phloem sieve elements of diseased plants and detection of phytoplasma-characteristic 16S rRNA gene sequence in DNA samples from diseased plants provided evidence linking the disease to infection by a phytoplasma. Results from restriction fragment length polymorphism, phylogenetic and comparative structural analyses of multiple genetic loci containing 16S rRNA, rpsS, rplV, rpsC and secY genes indicated that the AzLL phytoplasma represented a distinct, new 16Sr subgroup lineage, designated as 16SrI-T, in the aster yellows phytoplasma group. The genotyping also revealed that the AzLL phytoplasma represented new rp and secY gene lineages [rp(I)-P and secY(I)-O, respectively]. Phylogenetic analyses of secY and rp gene sequences allowed clearer distinctions between AzLL and closely related strains than did analysis of 16S rDNA.

AB A new genomic antibody (Ab) has been developed against a spore-wall protein SWP-32 of the honey bee intracellular pathogen, Nosema ceranae. In dot blots and Western blots this Ab specifically recognized N. ceranae spore antigens and did not cross-react with N. apis spore lysates, unless blots were overdeveloped. The detection sensitivity depends on both the concentration of the anti-SWP-32 Ab and the concentration of Nosema spores in the lysates. To avoid non-specific staining, we suggest using this new Ab at 1: 5000 dilution for detection of 1x10(3) and higher spore numbers per assay. Considering that a single infected bee can produce over 50 x 10(6) spores, this level of sensitivity will allow detection of a very low level of Nosema infection in bee colonies.

AB Intercropping of legumes with non-legumes is an ancient crop production method used to improve quality and dry matter (DM) yields of forage and grain, and to control weeds. However, there is little information regarding intercropping at high latitudes. The objectives of this field study were to evaluate performance of (1) sole cropped oat (Avena sativa L.) (cultivars Toral and Calibre) and pea (Pisum sativum L.) (cultivars Carneval and Orb) and their intercrop combinations, and (2) inter- and sole-crop responses to weeds. The different cropping systems were studied with different weed treatments (weed-free all season long, weed-free until flowering, and left weedy all season long). In general intercrops of oat and pea produced DM (forage) and grain yields similar to sole oat crops and higher than sole pea crops although the difference was not statistically significant. Furthermore, forage quality [ crude protein (CP), acid detergent fiber (ADF) and neutral detergent fiber (NDF)] was improved by intercropping. Most of the variables measured were unaffected by weed treatments, however weed DM was generally lower in sole oat and oat-pea intercropping than sole pea cropping systems. More than 80% of the weed DM was from common lamb's quarters (Chenopodium album L.). The CP of this weed was higher than oat and pea, and ADF and NDF were equivalent to the sole cropped oat. Thus, including weeds as part of the forage is possible. However, if crops are grown for grain, weeds are likely to produce large numbers of seeds that would enter the seed bank. Thus, pea-oat intercrops show potential as an alternative and sustainable approach for optimum yield and high quality forage and weed control under Alaskan subarctic conditions.

AB The Pacific oyster (Crassostrea gigas) is an important commercial species in the US Pacific Northwest with a history of production initially based on wild-caught seed imported directly from the Miyagi region of northern Japan (1920s-1970s) followed by an extended period of seed collection from a small number of naturalized, self-recruiting populations in US estuaries (early 1970s-present) and more recently through large-scale hatchery production of seed oysters (mid 1970s-present). I studied the genetic level consequences of each of these major transformations of the oyster industry by examining the patterns of private alleles (bands unique to one sample), the number of polymorphic loci, expected heterozygosity, genetic distance between populations and genetic divergence between individuals within and among three native Pacific oyster populations in Japan (Hiroshima, Miyagi, Midori River), five naturalized populations in North America (Pipestem Inlet BC, Nootka Inlet BC, Dabob Bay WA, Willapa Bay, WA, and Tillamook Bay, OR), two in New Zealand (Chance Bay and Kaipara Harbor), and seven domesticated and selectively bred cohorts from an ongoing genetic improvement program on the West Coast of the United States using amplified fragment length polymorphism (AFLP) markers. All but one of the naturalized populations in both the USA and New Zealand are genetically more similar to native populations from the Ariake Sea (Midori River) than to the Miyagi region of their origin, but all domesticated stocks more closely resemble the wild Miyagi population. According to local oyster producers, the one exceptional naturalized population (Tillamook) is a very recent colonization derived from farmed oysters. Such consistency is unexpected under random genetic drift, and I speculate that both natural and artificial selection may have altered AFLP allele frequencies in this species in the course of naturalization and domestication.

AB Rhizoctonia root rot causes serious losses on sugar beet worldwide. In order to help explain why Rhizoctonia root rot management practices have not performed well in some areas of the Intermountain West (IMW), a survey was conducted. In the IMW from 2004 to 2006, 94 Rhizoctonia solani field isolates were collected from sugar beet roots. These field isolates were compared with 19 reference strains and 46 accessions from GenBank for genetic diversity based on sequencing of the ITS-5.8S rDNA region. Greenhouse pathogenicity tests on sugar beet and silage corn were conducted and plant damage was assessed using a randomized complete block design with at least four replications. The majority of the isolates had sequence identity with the AG-2-2 IIIB (47%) or AG-4 subgroups (44%). Most of the AG-2-2 isolates (87%) were associated with fields in the western portion of the production area, while 71% of the AG-4 isolates came from the eastern portion of the production area. Isolates from AG-2-2 IIIB were frequently more virulent on sugar beet and sequence of the ITS-5.8s region required cloning because of genetic diversity within isolates. Seven (all AG-2-2 IIIB) of 18 isolates tested could attack both sugar beet and corn, while two of the seven virulent isolates caused less root rot on corn. To reduce Rhizoctonia root rot on sugar beet and corn, crop rotations and the isolates utilized for selecting host resistance could be given further consideration.

AB Emerging bioenergy markets portend both boon and bane for regions of intensive agricultural production worldwide. To understand and guide the effects of bioenergy markets on agricultural landscapes, communities, and economies, we engaged leaders in the Corn Belt state of Iowa in a participatory workshop and follow-up interviews to develop future policy scenarios. Analysis of workshop and interview data, in conjunction with the results of regional social and ecological research, was used to develop a heuristic model outlining interactions between key drivers and outcomes of regional landscape change. Three policy scenarios were built on this framework and included the following approaches: tweak, adapt, and transform. Our results suggest that if macroscale markets, technologies, and federal farm policies are allowed to be the overriding drivers of farm owner and operator decision making, Iowa's agricultural landscapes will likely become highly efficient at row crop production at the cost of other desired outcomes. However, the perspectives of Iowa leaders demonstrate how multifunctional agricultural landscapes can be achieved through a concerted portfolio of change coordinated across local, regional, and national scales.

ID ECOLOGICAL KNOWLEDGE; PERCEPTIONS; CHALLENGES
AB Interviews of tribal and nontribal residents of the Flathead Indian Reservation in Montana, U.S., were conducted to contrast the meanings that different cultures attach to the Mission Mountains Tribal Wilderness. Legislation that created a national system of wilderness areas ( in 1964 and still growing) was conceived, supported, and enacted by a fairly distinct social group generally residing in urban areas and schooled in modern civilization's scientific model and relationship with nature. The places this legislation protects, however, provide many other poorly recognized and little understood meanings to other parts of society. There is a link between indigenous people and nature that is not described well in this legislation or management policy in most places. The Wilderness Act suggests that these protected areas should be "untrammeled," or unmanipulated, unfettered, when in fact it is common knowledge that, for most areas in North America, indigenous people have intervened, with respect, for generations. The Mission Mountains Tribal Wilderness in Montana, though not part of the National Wilderness Preservation System, was designated to protect many of these same values but also extend to protect important cultural meanings assigned to this wild landscape. Protecting the relationship between indigenous people and relatively intact, complex systems, which we commonly refer to as wilderness in North America, can be an important contributor to sustainability of the landscape and cultural heritage.

TI Effects of producing maple syrup from concentrated and reconstituted

LA English
DT Article
DE Alternative sweeteners; evaporation; evaporator; maple sap; maple syrup;
membrane separation; sugar maple
AB Maple syrup is produced and marketed as a specialty, 'natural' sweetener with highly desirable properties, particularly its unique flavor and aroma profile. Pre-concentration of maple sap by membrane separation is used to increase the efficiency and profitability of maple production by reducing the time and fuel necessary to concentrate sap to maple syrup density using only the traditional method of thermal evaporation in open-pan style evaporators. However, there is some concern that producing syrup from sap concentrated by membrane processes to higher than previously standard concentration levels (5-8%) might yield negative impacts on the properties of maple syrup by reducing the length of time sap is processed with heat, which generates the majority of color, flavor, and aroma compounds. To investigate this question, experiments were conducted in which maple syrup was produced simultaneously from concentrated and reconstituted maple sap at four levels of sugar concentration, 2, 8, 12, and 15%. The chemical composition and flavor of the syrups produced were subsequently analyzed and evaluated. Maple syrup produced from more concentrated sap material was lighter in color, had a higher pH, and contained smaller quantities of invert sugar and volatile flavor compounds than syrup produced simultaneously with less concentrated sap material. However, differences observed in chemical composition were numerically small and not likely of practical significance. In addition, panelists in sensory evaluation experiments were unable to detect overall differences in the flavor of syrup produced simultaneously from sap material at 2 and 15% sugar concentration. The results indicate that chemical composition and flavor do not differ significantly in maple syrup produced from sap material of different sugar concentrations, and thus that producing syrup from sap concentrated by membrane separation to higher sugar concentration levels (up to 15%) is an acceptable method maple producers can use to increase the profitability of maple syrup production.

DT Article
DE chemical composition; remote sensing; sucrose; sugarcane
ID PLANT PIGMENTS; YIELD; SPECTROSCOPY
AB Remote sensing for crop maturity parameters may offer sugarcane producers a method to develop harvest schedules that maximize sucrose production. Several tests were conducted to determine if leaf reflectance measurements could be used to predict theoretically recoverable sugar (TRS) levels (crop maturity) prior to harvest. Leaf samples were collected from multi-variety first-ratoon (FR) sugarcane maturity studies in 2005 at three sample dates and from the plant-cane (PC) and first-ratoon (FR) sugarcane maturity studies throughout the 2006 September through December harvest season. Sugarcane juice was analyzed for its Brix, and sucrose content to predict TRS and leaf reflectance measurements were taken using a dual input, fiber optic spectrometer. Discriminant analysis showed that leaf reflectance was effective at predicting TRS in 56-79% of the cases if cultivars were combined using resubstitution and in 36-54 % of the cases using cross validation. If the cultivars were considered separately then 99-100% of the cases could be correctly classified using resubstitution and 60-100% of the cases using cross validation. Regression analyses between leaf reflectance values and TRS indicated that simple models could be developed that described much of the variability present in stalk sucrose levels. Several regions appeared to be important in describing stalk sucrose levels, including; the ultraviolet (250-330 nm), blue, green and yellow (450-590 nm), orange and red (590-650 nm), and the near-infrared (740-850 nm). These combined results indicate that it may be possible to utilize remote sensing techniques to estimate sugarcane maturity (TRS) prior to harvest.

AB There is growing interest for fishmeals and oils made from utilizing different fish by-products (heads, viscera, frames, etc.) that come directly from the commercial processing line. The major components of fish processing waste from salmon filleting operations are heads and viscera. In order to maximize the utilization of these individual by-products, the different fractions were evaluated. Analysis of essential amino acids in fishmeal showed significant differences in all essential amino acids except lysine. Differences were also noted in the levels of minerals, fatty acid methyl esters, biogenic amines, and fat soluble vitamins. The largest difference observed was in the level of retinol in the oil extracted from heads (8.9 +/- 1.0 g/g oil) and viscera (26.9 +/- 3.8 g/g oil). Head processing resulted in more lipids and cake, while the majority of viscera became stickwater. Results suggest that the fishmeal produced from different by-product parts can result in different nutritional values for feed or food ingredients.

AB Oil in water emulsions of several vegetable oils were studied in order to prepare a useful lubrication fluid. Several previously uncharacterized systems were studied in this paper, including those made from epoxidized vegetable oils. A series of different surfactants were studied in order to obtain emulsions suitable for lubrication applications. The epoxidized oils were found to form stable oil in water emulsions using several different surfactant systems. Only the (4) lauryl ether dodecyl polyethoxylated nonionic surfactant and a modified palm stearin methoxy ester ethoxylate were able to stabilize ordinary soybean oil for 1 week under our test conditions. Overall, the best surfactants were those with an HLB value slightly above 9. The droplet size of emulsions made with surfactants formed submicron droplets, whereas only droplets of larger diameter were obtained when surfactants were not added. Most importantly, a lubrication study was performed showing that even a 1% emulsion of the vegetable oils used in this study can reduce friction nearly as well as using the base oil alone.

AB Successful establishment and productivity of Populus depends upon adventitious rooting from: 1) lateral roots that develop from either preformed or induced primordia and 2) basal roots that differentiate from callus at the base of the cutting in response to wounding. Information is needed for phytotechnologies about the degree to which Populus adventitious rooting is controlled by effects of individual genotypes, waste waters used as alternative fertigation sources, and their interactions. Our objective was to irrigate twelve Populus clones with well water (control) or municipal solid waste landfill leachate and to test for differences between initiation of lateral versus basal roots, as well as root growth rate and distributional trends for both root types. We evaluated number and length of lateral roots initiated from upper, middle, and lower thirds of the cutting, as well as basal callus roots. Overall, leachate irrigation affected lateral roots but not basal roots, and there was broad clonal variation between and within root types. On average, there were 129% more lateral than basal roots, which ranged from 3 to 27 (lateral) and 2 to 10 roots (basal). The percent advantage of number of roots from the middle portion of the cutting relative to other sections was 120% (upper), 193% (lower), and 24% (basal). Clones, treatments, and their interaction did not affect root growth rate, which ranged from 1.5 +/- 0.6 to 3.4 +/- 0.3 cm d(-1), with a mean of 2.3 +/- 0.2 cm d(-1). These results contribute baseline information for clonal selection needed to establish Populus for phytotechnologies, energy, and fiber.

AB Logistic regression models were developed to identify significant factors that influence the location of existing wood-using bioenergy/biofuels plants and traditional wood-using facilities. Logistic models provided quantitative insight for variables influencing the location of woody biomass-using facilities. Availability of "thinnings to a basal area of 31.7m(2)/ha," "availability of unused mill residues," and "high density of railroad availability" had positive significant influences on the location of all wood-using faciities. "Median family income," "population," "low density of railroad availability," and "harvesting costs for logging residues" had negative significant influences on the location of all woodusing faciities. For larger woody biomass-using mills (e. g., biopower) availability of "thinnings to a basal area of 79.2m(2)/ha," "number of primary and secondary wood-using mills within an 128.8km haul distance," and "amount of total mill residues," had positive significant influences on the location of larger wood-using faciities. "Population" and " harvesting costs for logging residues" have negative significant influences on the location of larger wood-using faciities. Based on the logistic models, 25 locations were predicted for bioenergy or biofuels plants for a 13-state study region in the Southern United States.

AB Three switchgrass cultivars ('Performer', 'BoMaster', and 'Colony' switchgrass) were delignified using NaOH at varying concentrations and residence times at 121 degrees C for improved sugar production in enzymatic hydrolysis. Because of its greater carbohydrate/lignin ratio and the more substantial lignin reduction upon alkaline attack, 'Performer' switchgrass gave greater sugar productions under all the pretreatment conditions investigated. Maximum sugar production from 'Performer' was 425 mg/g raw biomass, which was achieved at 1% NaOH and 0.5 h. Sugar production increased with the improvement of delignification until the lignin reduction reached 30%. The more severe pretreatment conditions, which led to greater lignin reductions, did not favor the increase of sugar production because of greater solid losses. Linear models were proven effective in correlating a modified severity parameter log(M-o) to lignin reduction and sugar production of 'Performer' switchgrass.

AB Coal combustion by-products can lower soil phosphorus (P) solubility, but few studies have assessed their effect on runoff P. A soil with elevated P content was amended with fluidized bed combustion ash, flue gas desulfurization gypsum, and anthracite refuse ash at rates of 0-40 g kg-1 soil, and runoff from small plots was monitored over 3 years. In the first year, by-products lowered dissolved P in runoff by up to 47% below the untreated control; however, effects did not persist into the remaining years of the study. Total P losses were not significantly affected by coal combustion by-products, likely because of elevated particulate P losses. Water-extractable P was up to 40% less in treated soils than in untreated soils across the 3 years. Results demonstrate that although coal combustion by-products readily lower P solubility in soils, their impact on P losses in runoff can be undermined by erosional processes.

TI Allocating fuel breaks to optimally protect structures in the

SO INTERNATIONAL JOURNAL OF WILDLAND FIRE
LA English

ID UNITED-STATES; FIRE GROWTH; LANDSCAPE; CALIFORNIA; MANAGEMENT; BEHAVIOR;
OREGON; RISK; TIME
AB Wildland fire is a major concern in the wildland-urban interface (WUI), where human structures intermingle with wildland vegetation. Reducing wildfire risk in the WUI is more complicated than in wildland areas, owing to interactions between spatial patterns of housing and wildland fuels. Fuel treatments are commonly applied in wildlands surrounding WUI communities. Protecting the immediate surroundings of structures and building with fire-resistant materials might be more effective, but limited resources and uncooperative homeowners often make these impractical. Our question was how to allocate fuel treatments in the WUI under these constraints. We developed an approach to allocate fuel breaks around individual or groups of structures to minimise total treatment area. Treatment units were ranked according to their housing density and fire risk. We tested this method in a Wisconsin landscape containing 3768 structures, and found that our treatment approach required considerably less area than alternatives (588 v. 1050 ha required to protect every structure independently). Our method may serve as a baseline for planning fuel treatments in WUI areas where it is impractical to protect every single house, or when fire-proofing is unfeasible. This approach is especially suitable in regions where spotting is a minor cause of home ignitions.

AB Expansion of western juniper (Juniperus occidentalis Hook. var. occidentalis) has altered vegetation composition, fire behaviour and fire potential throughout south-western Idaho and eastern Oregon. Utilising GIS-derived products and fire-simulation software, the influence of the spatial arrangement of different woodland developmental stages on simulated surface fire occurrence was evaluated. Custom fuel models and a recent vegetation map processed in FARSITE under moderate fire conditions were used to create a fire-occurrence grid in three sixth-order watersheds on the Owyhee Plateau of south-western Idaho. Landscape pattern metrics were selected to quantify the spatial arrangement of plant communities within a neighbourhood around points from each successional stage randomly placed within each watershed. Linear regression analysis of fire occurrence and each of the selected landscape metrics was compared for four successional stages of western juniper encroachment to assess the effect of landscape-scale vegetation arrangement on fire occurrence. The landscape structure had little influence on whether an early-successional area burns in a surface fire, whereas the surrounding landscape structure influenced whether a late-successional or mature woodland area burned. Landscape metrics that showed significance in late-successional and mature woodland stages include patch density, mean area and Simpson's diversity.

ID URBAN INTERFACE
AB Recent ex-urban development within the wildland interface has significantly increased the complexity and associated cost of federal wildland fire management in the United States. Rapid identification of built structures relative to probable fire spread can help to reduce that complexity and improve the performance of incident management teams. Approximate structure locations can be mapped as specific-point building cluster features using cadastral data records. This study assesses the accuracy and precision of building clusters relative to GPS structure locations and compares these results with area mapping of housing density using census-based products. We demonstrate that building clusters are reasonably accurate and precise approximations of structure locations and provide superior strategic information for wildland fire decision support compared with area density techniques. Real-time delivery of structure locations and other values-at-risk mapped relative to probable fire spread through the Wildland Fire Decision Support System Rapid Assessment of Values at Risk procedure supports development of wildland fire management strategies.

ID COORDINATE; MODEL
AB A warm-season (May through October) Haines Index climatology is derived using 32-km regional reanalysis temperature and humidity data from 1980 to 2007. We compute lapse rates, dewpoint depressions, Haines Index factors A and B, and values for each of the low-, mid-and high-elevation variants of the Haines Index. Statistical techniques are used to investigate the spatial and temporal variability of the index across North America. The new climatology is compared with a previous climatology derived from 2.5 degrees (similar to 280 km) global reanalysis data. Maps from the two climatologies are found to be very similar for most of North America. The largest differences appear along the eastern coastline and in regions of large elevation gradients, where the orography in the 32-km climatology is better resolved than that of the 2.5 degrees climatology. In coastal areas of eastern North America and where there is steeply sloping terrain, the new climatology can augment the information from the 2.5 degrees climatology to help analyse the performance and interpret the results of the Haines Index in these regions. Alinear trend analysis of the total number of high-Haines Index days occurring in each warm season reveals no significant linear trends over the 28-year data period.

AB Avoidance of injury and death on the fireline may depend on firefighters voicing their concerns, but often this does not occur. Reasons for employee reticence identified in the literature include a perception of various personal costs or a belief that raising concerns is futile. Additionally, the social context may play a significant role. In a qualitative study using in-depth interviews with 36 wildland firefighters in the US, we explored reasons firefighters do or do not voice concerns. Findings revealed two primary themes related to initiating voice (limits to environmental perception and social influence) that vary considerably depending on a firefighter's career stage. Additionally, the tactics that firefighters use similarly vary with career stage. Rookies (novice firefighters) often lack the ability to discern and interpret environmental cues, rely on others to ensure safety, fear being stigmatised if they voice worries, and may believe no one will listen to them. Veteran firefighters - both mid-career experienced firefighters and expert veterans in high-experience leadership roles - are better able than rookies to perceive and describe risky situations and feel more confident to raise concerns. However, experienced firefighters still face social pressures that may lead them to remain silent. Expert veterans face fewer social pressures, but their roles can put them in situations where they are either complacent or distracted. Implications of these findings for firefighter training and fire leadership are discussed.

AB Long-term fire history reconstructions enhance our understanding of fire behaviour and associated geomorphic hazards in forested ecosystems. We used C-14 ages on charcoal from fire-induced debris-flow deposits to date prehistoric fires on Kendrick Mountain, northern Arizona, USA. Fire-related debris-flow sedimentation dominates Holocene fan deposition in the study area. Radiocarbon ages indicate that stand-replacing fire has been an important phenomenon in late Holocene ponderosa pine (Pinus ponderosa) and ponderosa pine-mixed conifer forests on steep slopes. Fires have occurred on centennial scales during this period, although temporal hiatuses between recorded fires vary widely and appear to have decreased during the past 2000 years. Steep slopes and complex terrain may be responsible for localised crown fire behaviour through preheating by vertical fuel arrangement and accumulation of excessive fuels. Holocene wildfire-induced debris flow events occurred without a clear relationship to regional climatic shifts (decadal to millennial), suggesting that interannual moisture variability may determine fire year. Fire-debris flow sequences are recorded when (1) sufficient time has passed (centuries) to accumulate fuels; and (2) stored sediment is available to support debris flows. The frequency of reconstructed debris flows should be considered a minimum for severe events in the study area, as fuel production may outpace sediment storage.

AB Coarse woody debris serves many functions in forest ecosystem processes and has important implications for fire management as it affects air quality, soil heating and carbon budgets when it combusts. There is relatively little research evaluating the physical properties relating to the combustion of this coarse woody debris with even less specifically addressing decomposition, a condition that eventually affects all debris. We review studies evaluating the combustion and consumption of coarse woody debris in the field and under controlled conditions. The thermal properties affected by decomposition are also reviewed, as are current modelling tools to represent their combustion. Management implications and suggestions for future research are then presented.

AB This paper quantifies current fire severity distributions for 19 different fire-regime types in Yosemite National Park, California, USA. Landsat Thematic Mapper remote sensing data are used to map burn severity for 99 fires (cumulatively over 97 000 ha) that burned in Yosemite over a 20-year period. These maps are used to quantify the frequency distributions of fire severity by fire-regime type. A classification is created for the resultant distributions and they are discussed within the context of four vegetation zones: the foothill shrub and woodland zone; the lower montane forest zone; the upper montane forest zone and the subalpine forest zone. The severity distributions can form a building block from which to discuss current fire regimes across the Sierra Nevada in California. This work establishes a framework for comparing the effects of current fires on our landscapes with our notions of how fires historically burned, and how current fire severity distributions differ from our desired future conditions. As this process is refined, a new set of information will be available to researchers and land managers to help understand how fire regimes have changed from the past and how we might attempt to manage them in the future.

AB Wildfire is a common natural disturbance that can influence stream ecosystems. Of particular concern are increases in water temperature during and following fires, but studies of these phenomena are uncommon. We examined effects of wildfires in 2000 on maximum water temperature for a suite of second- to fourth-order streams with a range of burn severities in the Bitterroot River basin, Montana. Despite many sites burning at high severity, there were no apparent increases in maximum water temperature during the fires. One month after fire and in the subsequent year, increases in maximum water temperatures at sites within burns were 1.4-2.2 degrees C greater than those at reference sites, with the greatest differences in July and August. Maximum temperature changes at sites >1.7 km downstream from burns did not differ from those at reference sites. Seven years after the fires, there was no evidence that maximum stream temperatures were returning to pre-fire norms. Temperature increases in these relatively large streams are likely to be long-lasting and exacerbated by climate change. These combined effects may alter the distribution of thermally sensitive aquatic species.

AB Wildfire is a major forest disturbance in interior Alaska that can both directly and indirectly alter ecological processes. We used a combination of pre- and post-fire forest floor depths and post-fire ground cover assessments measured in the field, and high-resolution airborne hyperspectral imagery, to map forest floor conditions after the 2004 Taylor Complex in Alaska's boreal forest. We applied a linear spectral unmixing model with five endmembers representing green moss, non-photosynthetic moss, charred moss, ash and soil to reflectance data to produce fractional cover maps. Our study sites spanned low to moderately high burn severity, and both black and white spruce forest types; high cover of green or non-photosynthetic moss in the remotely sensed imagery indicated low consumption, whereas high cover of charred moss, ash or soil indicated higher consumption. Strong relationships (R-2 = 0.5 to 0.6) between green moss estimated from the imagery and both post-fire depth and percentage consumption suggest that potential burn severity may be predicted by a map of green (live) moss. Given that the depth of the post-fire forest floor is ecologically significant, the method of mapping the condition of the organic forest floor with hyperspectral imagery presented here may be a useful tool to assess the effect of future fires in the boreal region.

AB Residents' trust in the managing agency has been heralded as a necessary precursor to success in preventing wildland fire losses in the wildland-urban interface. Trust, however, is a complex concept. Homeowners' specific fire wise actions may not be easily linked to general measures of trust. This article uses two distinct trust indices to predict residents' intention to do fire wise actions to their house and adjacent site. Results of structural equation models using a survey of Colorado Front Range residents (n = 456) revealed strong explanatory power: 85% (house behaviours) and 72% (site behaviours) of the variation in intentions were accounted for by trust, previous fire wise behaviours and the perceived effectiveness of the actions. The trust measures, however, were not major influences. 'Trust in agency competence' weakly predicted perceived effectiveness for site behaviours; 'trust in agency information' weakly predicted past house behaviours. Neither trust variable directly affected intentions to perform these actions. We conclude that trust is best viewed as a broad precursor whose influence on behavioural intentions is mediated by other constructs (e. g. past behaviour, perceived effectiveness). The implications for further work to understand the role of trust and the possible social mechanisms involved are discussed.

AB This review describes the development of the multiplex PCR detection kit for Salmonella spp., Listeria monocytogenes, and Escherichia colt O157:H7 in food samples. To develop a detection assay, our research team evaluated the optimization of the pre-enrichment broth, the simple DNA extraction method, and the multiplex PCR settings. When this detection protocol was used to detect the above pathogenic bacteria, one cell per 25 g of inoculated sample was detected within 24 h. Moreover, there was excellent agreement between the multiplex PCR assay and the conventional culture method. The multiplex PCR detection assay system was confirmed to be a reliable and useful method for the rapid screening of food products for foodborne pathogens. The assay system was commercialized as a "(TA10] Pathogenic Bacterial Multiplex PCR Detection Kit". When this kit was provided to four different laboratories for an extensive validation study, there were no significant differences in detection sensitivity among the laboratories. The detection kit will be valuable as a screening method for foods contaminated with these pathogens, and it will also be useful for identifying the sources of outbreaks of foodborne illness.

AB Metallothinonein-III (MT-III) as a new member of the Metallothionein (MT) family has specific physiological effects different from known MT-I and MT-II. In this study, the yak MT-III gene coding region was amplified and cloned by RT-PCR from brain tissue of yak using YMT-III(SP1) and YMT-III(SP2) as specific primers. The isolated cDNA sequence of MT-III was 207 bp in length (Genbank accession, NO, DQ323545) and was subjected to BLASTn searching in NCBI. Results of the search indicate the nucleotide sequences of yak share 98, 97, 96, 92, 91, 90, 89, 88 and 86% sequence similarity with cattle, milk goat, pig, sheep, chimpanzee, human, dog and house mouse, respectively. Comparing homologies of MT-III sequences with MT-I and MT-II in yak, we found 69 and 67% homologies, respectively. The MT-III protein was composed of 68 amino acids, including 19 cysteines, similar to the number of cysteines of sheep but not human and mouse which lack the conserved ninth cysteine and have no aromatic amino acids. There were conserved motifs of MTs, such as C-X-C, C-C-X-C-C, C-X-X-C and KKS and specific motifs including MDPE, CPCP in MT-III. This conservation of motifs suggests a conservation of MT-III in molecular evolution. The MT-III in yak had no signal peptide and represented a form of cytoplasmic protein similar to MT-I/II. There were few sheets in secondary protein structures, obvious helices in 39-46th AA and mainly irregular curling in the 2D-structure of MT-III protein. The lack of the conserved ninth cysteine in yak MT-III merits further research.

AB We assessed the accuracy and precision of visual estimates from two divers and photogrammetric measurements from a diver-operated stereo-video camera system for determining the length of Saratoga Springs pupfish Cyprinodon nevadensis nevadensis (12-36 mm total length) under controlled conditions. Visual estimates by two divers differed significantly from true fish length (P < 0.001) but were not significantly different from each other (P = 0.42). Levels of accuracy and precision were similar to those previously reported for visual estimates by divers. On average, the two divers underestimated fish length by 2.74 mm (11%) and 2.93 mm (12%). The magnitude of underestimation error increased with fish length. Photogrammetric measurements from a stereo-video camera system were more accurate and precise than diver estimates of fish length. Little to no bias was evident (mean error = 0.05 mm), and the level of precision (coefficient of variation of the difference between observed length and true length) was 4.5% for the photogrammetric measurements compared with 10% and 11% for the two divers' estimates. In comparison with underwater visual surveys, surveys that use a stereo-video camera system may increase the consistency of long-term data sets and improve resolution to detect important length differences in small-bodied fishes. Managers must remain careful to avoid or correct sampling biases, which can affect underwater visual surveys and stereo-video surveys alike.

AB Variance estimators for probability sample-based predictions of species richness (S) are typically conditional on the sample (expected variance). In practical applications, sample sizes are typically small, and the variance of input parameters to a richness estimator should not be ignored. We propose a modified bootstrap variance estimator that attempts to capture the sampling variance by generating B replications of the richness prediction from stochastically resampled data of species incidence. The variance estimator is demonstrated for the observed richness (SO), five richness estimators, and with simulated cluster sampling (without replacement) in 11 finite populations of forest tree species. A key feature of the bootstrap procedure is a probabilistic augmentation of a species incidence matrix by the number of species expected to be 'lost' in a conventional bootstrap resampling scheme. In Monte-Carlo (MC) simulations, the modified bootstrap procedure performed well in terms of tracking the average MC estimates of richness and standard errors. Bootstrap-based estimates of standard errors were as a rule conservative. Extensions to other sampling designs, estimators of species richness and diversity, and estimates of change are possible.

AB We measured the dynamics of both biomass and nutrient pools on 7-, 17-, 31- and 51-year-old Pinus massoniana plantations in southern China. Using a chronosequence approach, we found that biomass of each component increased with aging while its proportion decreased except stem-wood. Nutrient pools varied with biomass pools except for foliage. For all harvest intensities (stem only, stem and branches, and aboveground), increasing the rotation length from 31 yrs to 51 yrs increased the biomass collection by >= 7.1% and reduced the nutrient export for K, Ca and Mg by <= 6.3% during 155 years, while N and P pools varied with harvesting intensities. A decreasing rotation length from 51 yrs to 17 yrs would increase the biomass collection by >= 12.4%, but remove significantly more nutrients. Although more biomass would be collected if harvesting intensity increased, the nutrient removal would have disproportionally increased. Therefore, increasing the rotation length and decreasing harvest intensity are recommended to sustain the site productivity for future Masson pine plantation.

TI Design of Field Experiments: Influence of Treatment Response Relative to
Standard Deviation and Blocking Factor Characteristics on Efficient
Blocking Strategy
SO JOURNAL OF THE AMERICAN POMOLOGICAL SOCIETY
LA English
DT Article
AB Selection of experimental design can markedly influence efficiency of field research. This study used Monte Carlo simulations to compare the ability of different field experimental designs to distinguish defined treatment differences, and the paper concludes with a section on practical use of the information obtained. In each simulation, a single experimental treatment was compared to a control treatment and each treatment was applied to twelve trees representing similar research effort. Experimental designs compared were twelve blocks with a single tree per treatment, six blocks of two trees per treatment, four blocks of three trees per treatment, and two blocks with six trees per treatment. In each case, analyses were compared in which data were collected with single tree experimental units (multiple trees independently assigned the same treatment within each block) or as is often done with spatial blocking, data were pooled on a group of trees (one data point per multiple tree experimental unit). Trees were blocked according to a specified factor, which was quantified for these comparisons but could represent a qualitative factor such as spatial position. The probability of rejecting the null hypothesis was computed for a range of situations including small and large values for the following parameters: treatment response, standard deviations of the response, blocking factor effects, and blocking factor standard deviations. In all cases, the probability of rejecting a false null hypothesis was significantly greater when data were collected on single-tree experimental units, and decreased as the number of trees pooled per data point increased (and number of blocks decreased). When data were collected on single-tree experimental units and the factor used for blocking actually had no relationship to the response variable, all four designs had similar probabilities of rejecting the null hypothesis; however, power decreased with increasing block size (more trees per block but fewer blocks) when the blocking factor was significantly correlated with the response variable but treatment did not change the slope of the blocking factor vs. response variable. When the blocking factor effect was significant and there was a significant treatment-by-block interaction, use of a single tree per treatment per block had the least power, but power decreased substantially with block size greater than two trees per treatment. In the last case, failing to account for block by treatment interaction effects resulted in test statistics having little power to reject the null hypothesis even when treatment effects were strong. These analyses indicate that use of one or two trees per treatment per block with data collected on individual-tree experimental units provides the greatest efficiency in distinguishing treatment effects, and that two trees per treatment per block is superior when there is a significant treatment-by-blocking factor interaction. When the blocking factor displayed a distinct spatial trend, incorrectly using individual tree data from multi-tree experimental units as pseudo-replicates resulted in false rejections of the null hypothesis well beyond the specified alpha=0.05, sometimes approaching P=0.50. Researchers are cautioned that proper analysis of multi-tree experimental units yields the same F-test using individual subsample data or single mean values representing each collective experimental unit.

TI Six-Year Performance of 14 Prunus Rootstocks at 11 Sites in the 2001
NC-140 Peach Trial
SO JOURNAL OF THE AMERICAN POMOLOGICAL SOCIETY
LA English
DT Article
AB Fourteen Prunus rootstock cultivars and selections budded with either 'Redtop'. Redhaven' or 'Cresthaven' peach [Prunus persica (L.) Batsch] were planted at 11 locations in North America in 2001 in a randomized block design with a tree spacing of 5 by 6 m and 8 replicates. This test planting was an NC-140 Cooperative Regional Rootstock Project (www.nc140.org). There were 14 rootstocks in total, which included three peach seedling rootstocks: Lovell, Bailey, and Guardian (R) 'BY520-9' [selection SC-17]. Clonal rootstocks included the peach x almond hybrids BH-4 and SLAP (Cornerstone); peach a plum hybrids K146-43 (Controller 5), K146-44, and P30-135 (Controller 9); interspecific plum hybrids Hiawatha, Jaspi and Julior; interspecific Prunus hybrids Cadaman (R) and VVA-1 (Krymsk (R) 1); and Prunus pumila L. selection Pumiselect (R). Final tree size was largest in California, Georgia, Maryland, and South Carolina. BH-4, SLAP, SC-17, Lovell, and Cadaman were the most vigorous rootstocks. Jaspi, K146-43, K146-44 and VVA-1 were the least vigorous, having trunk cross-sectional areas 20-50% of Lovell-rooted trees. No rootstock had a significantly higher survival rate than Lovell at all locations, but Bailey, K146-44, and P30-135 had good survival at all test sites. Julior and Jaspi consistently produced root suckers. Pumiselect (R) had anchorage problems at several locations. Cumulative fruit yields were highest on the peach seedling, peach x almond, and Cadaman (R) rootstocks. Lowest cumulative yields were from the small trees on Jaspi, VVA-1 and K146-44 rootstocks. Fruit weight did not differ much among rootstocks though cultivars on Pumiselect (R) and K146-43 often had smaller fruit. Cumulative yield efficiency was not consistently related to tree size. Rootstocks influenced dates of bloom and harvest, but not in a consistent manner across locations/cultivars.

AB Preplant fumigants and nematode-resistant rootstocks were evaluated as alternatives to methyl bromide in a vineyard replant situation. Two months after fumigation, Thompson Seedless on its own roots, Merlot on 1103 Paulsen rootstock, and Thompson Seedless on Freedom rootstock were planted. The study revealed that 1,3-dichloropropene plus chloropicrin (578 kg/ha shank injected), iodomethane plus chloropicrin (515 kg/ha shank injected or 448 kg/ha drip applied), and propargyl bromide (221 kg/ha shank injected or 207 kg/ha drip applied) generally controlled root-knot (Meloidogyne spp.) and citrus (Tylenchulus semipenetrans) nematodes as well as methyl bromide (507 kg/ha shank injected) over an 8-year evaluation period. Sodium azide (336 kg/ha drip applied followed with either a water cap or tarp), metam sodium (124 kg/ha applied with microspray sprinklers), and chloropicrin alone (448 kg/ha drip applied) were less effective. In general, the effect of fumigants on nematode control was very evident in the own-rooted Thompson Seedless. The 1103P rootstock was partially tolerant to root-knot and citrus nematodes for the first 3 to 4 years, respectively, before nematode populations began to rebuild. In contrast, Freedom rootstock proved to be highly resistant and kept root-knot nematode populations low during the 8-year evaluation. However, preplant fumigation is still likely to be required in fields where citrus nematodes are present. Application of propargyl bromide and replanting with Merlot on 1103P rootstock was the only fumigant-rootstock combination that resulted in grape yield similar to methyl bromide. However, this effect was observed only during the first four years of fruit production. The other fumigant and cultivar combinations did not result in yield differences compared to the untreated control.

AB Estolides are a developing class of natural and synthetic compounds that have been synthesized from hydroxy oils like castor and lesquerella or by the condensation of fatty acids across the olefin of a second fatty acid. Castor and lesquerella estolides are derived from either their triglycerides or their free fatty acids utilizing their hydroxyl moiety to establish the estolide bond. The triglyceride estolides have pour points of 9 to -36 degrees C but suffer poor oxidative stability with RPVOT times of 29 - 52 minutes even with 1% of an anti-oxidant package incorporated into the samples. In contrast to the triglyceride estolides of castor and lesquerella, the estolides from lesquerolic and ricinoleic acids have very good pour points of -36 to -54 degrees C. Estolides derived from the acid catalyzed condensation of oleic acid with a variety of fatty acids can be made in good yield and posses a wide range of physical properties. Of particular interest are the saturated capped estolides of oleic that have both good low temperature properties (pour point -5 to - 39 degrees C) and good oxidative stability. Estolides from meadowfoam fatty acids do not have good low temperature properties but have been extensively used in cosmetics where they provide good moisturizing properties.

AB The Florida pompano Trachinotus carolinus is a highly prized marine fish species, the larviculture of which currently includes the feeding of live rotifers and nauplii of brine shrimp Artemia spp. However, no previous studies have evaluated the feeding of copepod nauplii. In this study, the growth and survival of Florida pompano larvae fed nauplii of the calanoid copepod Pseudodiaptomus pelagicus were compared with those of larvae fed the standard reference diet of enriched rotifers Brachionus plicatilis. Experiments were conducted during the first 7-9 d posthatch (DPH), a period preceding the provision of Artemia nauplii. Treatments included feeding only copepod nauplii during the first day, the first three days, and on all days, as well as copepod nauplii mixed with rotifers during the entire experiment. In addition, the dietary effects on larval fatty acid composition were examined. Feeding copepod nauplii at a density of 2.0-3.5 nauplii/mL during the first day or the first three days of feeding had advantages over feeding only rotifers. However, after approximately 3 DPH, increased quantities of nauplii were needed to provide sufficient nutrients for growth. This was demonstrated in larvae fed copepod nauplii for the entire trial, for which survival was significantly higher than for the other treatments but for which growth was significantly reduced. Larvae fed a mixture of rotifers and nauplii for the entire trial had survival similar to that of larvae fed only rotifers (40%); however, growth was greater in larvae fed the mixed diet, suggesting that there is a nutritional advantage to including copepods in the diet. Fatty acid analyses revealed that increased levels of docosahexaenoic acid were associated with larvae fed copepods, which probably contributed to the observed higher survival and growth. These results indicate that there are multiple benefits to feeding copepods to Florida pompano larvae.

AB The study compared the effects of water stress under ambient (350mol mol-1) and elevated (700mol mol-1) carbon dioxide concentrations on canopy carbon assimilation rates, soil water use, and water use efficiency (WUE) of cotton plants on a daily basis. This research was carried out in four sun-lit SPAR (Soil Plant Atmosphere Research) units with soil bins located at Beltsville, Maryland, USA. Whole canopy net photosynthetic rates were recorded at 5-min intervals, and soil water content was measured hourly using time-domain reflectometry. Pre-dawn and mid-day leaf water potentials were measured during the water stress and the recovery periods. The soil water use rates of plants grown under elevated CO2 were significantly lower than those grown under ambient levels for both water-stressed and well-watered plants. The WUE of the ambient treatment did not begin to increase until most of the available water was depleted from the soil. The elevated CO2 non-irrigated treatment was able to maintain carbon assimilation rates similar to that of the well-watered treatment while decreasing water uptake during the first 10 days of the drying period. Both water use and carbon assimilation rates decreased in the ambient non-irrigated treatment, shortly after withholding water. Plants grown at 350mol mol-1 CO2 concentration depleted more water from the deepest part of the profile (0.35-0.85m) than did the plants from the elevated CO2 treatment.

AB Unmanned aerial systems (UAS) have great potential as a platform for acquiring very high resolution aerial imagery for vegetation mapping. However, image processing and classification techniques require adaptation to images obtained with low-cost digital cameras. We developed and evaluated an image processing workflow that included the integration of resolution-appropriate field sampling, feature selection, and object-based image analysis for the purpose of classifying rangeland vegetation from a five-centimeter-resolution UAS image mosaic. Classification tree analysis was used to determine the optimal spectral, spatial, and contextual features. Segmentation and classification rule sets were developed on a test plot and were applied to the remaining study area, resulting in an overall classification accuracy of 78% at the species level and 81% at the structure-group level. The image processing approach provides a roadmap for deriving quality vegetation classification products from UAS imagery with very high spatial, but low spectral resolution.

AB Many small unmanned aerial systems use true-color digital cameras for remote sensing. For some cameras, only the red channel is sensitive to near-infrared (NIR) light. Given a camera with this spectral capability, we modified it to obtain NIR-green-blue images. One advantage of this low-cost system is that images can be inspected directly from the camera. This camera was flown in a Piper Cub aircraft for estimating biomass of wheat and barley planted as winter cover crops. There was much greater variation in biomass within experimental strips than among strips, so correlations were not high. This research demonstrates the need to develop better calibration methods so inexpensive camera sensors can be used in precision agriculture.

AB Apparent amylose content is a key element for characterizing a rice (Oryza sativa L.) cultivar for cooking quality. However, cultivars with similar apparent amylose content can have widely varying quality attributes, including major parameters of flour paste viscosity. It has been postulated that the presence of a rice Waxy gene single nucleotide polymorphism (SNP) marker is associated with elevated Rapid Visco Analyser (RVA) properties in specific high amylose rice cultivars. A mapping population derived from a cross between two varieties, Cocodrie and Dixiebelle, having similar high apparent amylose contents, but with different paste viscosity properties and Waxy gene markers was analyzed for the genetic segregation of various pasting properties, measured with RVA instrumentation. Marker inheritance analyses revealed that the Waxy exon 10 SNP marker was associated with the proportion of soluble to insoluble apparent amylose and most RVA pasting measurements. Waxy gene markers can be used to efficiently improve the selection of rice with desirable characteristics, particularly for superior parboiling and canning quality. Published by Elsevier Ltd.

AB Ruffed grouse (Bonasa umbellus) are a popular game bird and the management indicator species for quaking aspen (Populus tremuloides) in the Black Hills National Forest (BHNF), which requires development of a robust monitoring protocol to evaluate trends in ruffed grouse populations. We used roadside drumming surveys in spring 2007 and 2008 to estimate ruffed grouse occupancy and detection probabilities in the BHNF while simultaneously assessing the influence of sampling and site covariates on these processes. Ruffed grouse occupancy estimates were constant between spring 2007 and 2008 (psi = 0.12, SE = 0.03) and were positively influenced by the amount of aspen surrounding the site. Detection probability estimates were constant between spring 2007 and 2008 (p = 0.27, SE = 0.06) and were influenced by survey date in a quadratic form and negatively influenced by wind speed and time of the survey. Collectively, our results demonstrated that ruffed grouse occupancy and detection probabilities in the BHNF were low. Occupancy could be increased by increasing the extent of aspen. To improve monitoring efficiency and maximize probability of detecting ruffed grouse, ruffed grouse monitoring should be conducted during the peak of drumming (mid-May), during favorable weather conditions such as low wind speeds and little precipitation, and during early morning, near sunrise.

AB We tested a bioenergetics model integrated within a mortality model that estimates numbers of European starlings (Sturnus vulgaris) poisoned with the avicide, Compound DRC-1339 Concentrate. The bioenergetics model predicted daily metabolic rate. Accuracy and reliability of this variable is critical because other algorithms (e.g., toxicity regressions, feeding behavior) in the mortality model depend on metabolic rate to calculate the amount of DRC-1339 ingested per bird. We tested the bioenergetics model by comparing its estimates of metabolic rate with those generated from measuring feeding rates of caged starlings during a feeding trial conducted outdoors during January 2008. Over the 12-day feeding trial, daily feeding rates of caged starlings indicated that metabolic rates ranged from 157 kJ/bird per day to 305 kJ/bird per day. The bioenergetics model predicted metabolic rates ranging from 208 kJ/bird per day to 274 kJ/bird per day. There was no difference between these 2 independently derived estimates of daily metabolic rate (paired t-test: t((11)) = 1.4, P = 0.18). Using 95% confidence intervals calculated from variation of feeding rates among cages (n = 4, 6 birds/cage), the bioenergetics model's estimates were within 95% confidence intervals on 9 of 12 days and greater than the upper 95% confidence interval on 3 days. Daily estimates of metabolic rate were directly correlated between the bioenergetics model and the feeding-rate model (r(12) = 0.57, P = 0.05). A broad range of temperatures (-17 degrees C to 14 degrees C), wind speeds (0-40 km/hr), and percent cloud cover (0-100%) were encountered during the feeding trial. The bioenergetics model's predictions appeared robust to varying meteorological conditions typical of winters in middle latitudes of the interior United States. Compound DRC-1339 Concentrate is used by USDA Wildlife Services to manage chronic infestations of starlings at livestock facilities, which occur mainly during fall and winter. Compared to other methods used for estimating DRC-1339 mortality (e.g., counting birds pre- and posttreatment), bioenergetics modeling should improve the mortality model's overall accuracy and precision.

AB We conducted the most intensive estimate of the endangered Lower Keys marsh rabbit (Sylvilagus palustris hefneri) metapopulation to date using pellet surveys and capture-recapture methodology. We livetrapped 83 rabbits, evaluated 5 closed population models, and selected the model that best represented the data. We considered the variation in behavioral response model the best model and correlated (r(2) = 0.913) its patch population estimates to patch pellet densities. From the prediction equation, we generated a range-wide metapopulation estimate of 317 rabbits, a western clade population of 257 rabbits, an eastern clade population of 25 rabbits, and translocated marsh rabbit populations of 35 and zero on Little Pine and Water keys, respectively. A subset of patches whose marsh rabbit subpopulations were last estimated in 1993 exhibited a 46% decline in abundance over 15 yr. Due to the low estimate of the eastern clade population, special effort should be initiated to avoid loss of genetic diversity. The prediction equation suffers from limited data at high pellet densities, patches with >= 5 pellets/m(2). Future studies should investigate if the slope of the regression is indeed near 1 by sampling patches across the range of pellet densities, especially those with >= 5 pellets/m(2). The equation provides managers a quick, efficient, and noninvasive method to estimate marsh rabbit abundance from pellet counts but the confidence of predicted rabbit densities from high pellet density patches is low.

AB Knowledge of how landscape features affect wildlife resource use is essential for informed management. Resource selection functions often are used to make and validate predictions about landscape use; however, resource selection functions are rarely validated with data from landscapes independent of those from which the models were built. This problem has severely limited the application of resource selection functions over larger geographic areas for widely distributed species. North American elk (Cervus elaphus) is an example of a widely-distributed species of keen interest to managers and for which validation of resource selection functions over large geographic areas is important. We evaluated the performance of resource selection functions developed for elk on one landscape in northeast Oregon with independent data from a different landscape in the same region. We compared predicted versus observed elk resource use for 9 monthly or seasonal periods across 3 yr. Results showed strong, positive agreement between predicted and observed use for 2 spring and 3 late summer-early fall models (3-yr r = 0.81-0.95). Predicted versus observed use was negatively or weakly positively correlated for 3 summer models and 1 mid-fall model (3-yr r = 0.57-0.14). Predicted and observed use correlated well when forage was limited ( spring and late summer or early fall), corresponding to important biological stages for elk (parturition and breeding seasons). For these seasonal periods, model covariates such as rate of motorized traffic and canopy closure often were effective predictors of elk resource selection. The models we validated for spring and late summer-early fall may be used to evaluate management activities in areas with similar landscape characteristics. (C) 2011 The Wildlife Society.

AB Densely vegetated environments have hindered collection of basic population parameters on forest-dwelling ungulates. Our objective was to develop a mark-recapture technique that used DNA from fecal pellets to overcome constraints associated with estimating abundance of ungulates in landscapes where direct observation is difficult. We tested our technique on Sitka black-tailed deer (Odocoileus hemionus sitkensis) in the temperate coastal rainforest of Southeast Alaska. During 2006-2008, we sampled fecal pellets of deer along trail transects in 3 intensively logged watersheds on Prince of Wales Island, Alaska. We extracted DNA from the surface of fecal pellets and used microsatellite markers to identify individual deer. With genotypes of individual deer, we estimated abundance of deer with moderate precision (+/- 20%) using mark-recapture models. Combining all study sites, we identified a 30% (SE 5.1%) decline in abundance during our 3-year study, which we attributed to 3 consecutive severe winters. We determined that deer densities in managed land logged > 30 years ago (7 deer/km(2), SE = 1.3) supported fewer deer compared to both managed land logged < 30 years ago (10 deer/km(2), SE = 1.5) and unmanaged land (12 deer/km(2), SE = 1.4). Our study provides the first estimates of abundance (based on individually identified deer) for Sitka black-tailed deer and the first estimates of abundance of an unenclosed ungulate population using DNA from fecal pellets. Our tool enables managers to accurately and precisely estimate the abundance of deer in densely vegetated habitats using a non-invasive approach. (C) 2011 The Wildlife Society.

AB Aquaculture methods for queen conch Strombus gigas have been established for several decades. However, there is a need to improve husbandry techniques for the grow out of juveniles. The purpose of this study was to determine the growth and survival of juvenile queen conchs fed artificial diets with increasing levels of a red alga Agardhiella sp. Agardhiella, soy protein isolate, and fish oil were increased at the expense of catfish feed, wheat flour, or both to keep the diets isonitrogenous (38% crude protein [CP]) with increasing protein to energy ratios (83-96 mg CP/kcal). Yttrium was also incorporated as an inert marker for determining the digestibility of dietary nutrients. Juvenile queen conchs were stocked at 75/m2 for a total of 16 conchs per replicate (three replicates) and were fed 125 mg of diet per conch each day for 6 months. Dietary crude protein ranged from 31% to 38%. The dietary lipid, moisture, energy, ash, fiber, carbohydrate, and yttrium in each diet were also determined. Juvenile conchs were measured (shell length and wet weight) every 6 weeks. At the end of the experiment, feces were collected to determine protein, energy, and dry matter digestibility. Results indicated the highest growth rates (0.10 mm/d and 0.11 mm/d) and survival were for conchs that were fed diets containing a soy protein isolate protein substitution of 15% or less. This study highlights the importance of the protein source in the artificial diets of juvenile queen conchs.

AB Translocations to recover native fishes have resulted in mixed success. One reason for the failure of these actions is inadequate assessments of their feasibility prior to implementation. Here, we provide a framework developed to assess the feasibility of one type of translocation-reintroduction. The framework was founded on two simple components of feasibility: the potential for recipient habitats to support a reintroduction and the potential of available donor populations to support a reintroduction. Within each component, we developed a series of key questions. The final assessment was based on a scoring system that incorporated consideration of uncertainty in available information. The result was a simple yet transparent system for assessing reintroduction feasibility that can be rapidly applied in practice. We applied this assessment framework to the potential reintroduction of threatened bull trout Salvelinus confluentus into the Clackamas River, Oregon. In this case, the assessment suggested that the degree of feasibility for reintroduction was high based on the potential of recipient habitats and available donor populations. The assessment did not provide a comprehensive treatment of all possible factors that would drive an actual decision to implement a reintroduction, but it did provide a fundamental level of feasibility assessment that is often lacking in practice.

TI An Evaluation of Underwater Epoxies to Permanently Install Temperature
Sensors in Mountain Streams
SO NORTH AMERICAN JOURNAL OF FISHERIES MANAGEMENT
LA English
DT Editorial Material
AB Stream temperature regimes are of fundamental importance in understanding the patterns and processes in aquatic ecosystems, and inexpensive digital sensors provide accurate and repeated-measurements of temperature. Most temperature measurements in mountain streams are made only during summer months because of logistical constraints associated with stream access and concerns that large annual floods will destroy sensor installations. We assessed six underwater epoxies to determine whether sensors could be attached to large rocks already in streams to provide durable installations and whether temperature measurements would be biased by heat conduction through the rocks. Only one of the six test epoxies bonded the sensors firmly to rock surfaces in laboratory trials. In subsequent field trials, 9 of 11 sensors attached to rocks with this epoxy successfully weathered above-average floods in four Idaho and Nevada streams in 2010. Comparisons of daily maximum, minimum, and mean temperatures between rock-mounted sensors and control sensors at 10 rocks suggested temperature measurements were not biased by attachment to rocks. We also assessed the effect of direct sunlight on sensors by removing solar shields from some sensors and noted rapid and statistically significant increases in daily means (+0.21 degrees C) and maxima (+0.54 degrees C), but not minima (-0.01 degrees C). Use of underwater epoxy for permanent installation of temperature sensors in mountain streams is a viable technique if an appropriate epoxy is chosen, sensors are shielded from direct sunlight, and rocks large enough to withstand floods are used. Moreover, installations using epoxy are rapid (approximately 20 min), and firm attachments to rock surfaces over a range of stream temperatures (5-20 degrees C) are possible.

It can be used for the two-carbon homologation of aldehydes to , -unsaturated aldehydes. The reagent can be prepared in good overall yield (82%) and purity by deprotection of commercially available diethyl-2,2-(diethoxy)ethylphosphonate with p-toluenesulfonic acid in 1.5% aqueous acetone to give diethyl formylmethyl-2-phosphonate, followed by a simple preparation of the dimethylhydrazone derivative with N,N-dimethylhydrazine.

TI FIBER OPTIC YIELD MONITOR FOR A SUGARCANE HARVESTER
SO TRANSACTIONS OF THE ASABE
LA English
DT Article
DE GPS; Mapping; Precision agriculture; Sugarcane; Yield monitor
AB A fiber optic yield monitoring system was developed for a sugarcane chopper harvester that utilized a duty-cycle type approach with three fiber optic sensors mounted in the elevator floor to estimate sugarcane yield. Field testing of the monitor demonstrated that there was a zero intercept linear relationship between the optical sensor response and the actual sugarcane yields with an R(2) value of 0.98. The average observed prediction error on 0.5 to 1.6 Mg estimates was 7.5%; however, the magnitude of the error decreased as the harvested area (tonnage) increased, with an estimated error of 0.03% for 57.8 Mg loads. Factor testing indicated that the duty cycle reading was not affected by sugarcane variety, harvester speed, harvested distance, or direction of cut (lay of the sugarcane). Field testing across several locations in the U.S. totaled more than 557 h of operation and indicated that the system was robust, maintenance free, and self-cleaning, but some obstruction of the fiber optic sensors did occur in wet, muddy soils. These obstructions were minimized by relocating the fiber optics closer to the bottom of the elevator and leaving holes on each side of the sensors to enhance cleaning and scouring. This monitoring system compares well with all previously tested methods and is very durable and easy to install.

ID SPRAY; SAMPLERS
AB Measurements of spray volume and droplet size are critical to evaluating the movement and transport of applied sprays associated with both crop production and protection practices and vector control applications for public health. Any sampling device used for this purpose will have an efficiency of collection that is a function of the sampling device itself the droplet size of the spray being sampled, and the airspeeds under which the sampling is conducted. This study focuses on two rotary impaction devices, the Hock and the FLB samplers, that were evaluated under two droplet sized sprays and four airspeeds. The collected spray concentrations were compared to standard passive samplers whose theoretical collection efficiency was calculated and used to estimate the actual spray volume sampled. Additionally, droplet sizing information derived from image analysis of droplet deposits on the rotary impactor collection surfaces was compared to actual measurements of droplet size of the sampled spray cloud. Generally, overall collection efficiencies ranged from 2.5% to 20%, with the FLB being more efficient than the Hock and with lower efficiencies at higher airspeeds for both samplers. Comparison of the droplet sizing data showed that the FLB sampler tended to underpredict the D(V10) and D(V50) data, while the Hock tended to overpredict the D(V50) and D(V90) data.

AB Infrared (IR) radiation heating could provide a high heating rate and rapid moisture removal for rough rice drying. The objective of this research was to investigate the effect of the drying bed thickness on drying characteristics and quality of rough rice subjected to IR heating. Samples of freshly harvested medium grain rice (M202 variety) with 20.5% and 23.8% (w.b.) moisture contents were used for this study. They were dried with two different radiation intensities (4685 and 5348 W m(-2)) and exposure times of 15, 30, 40, 60, 90, and 120 s for each drying bed thickness. The three tested drying bed thicknesses were single layer, 5 mm, and 10 mm. After IR drying, the samples were tempered for 4 h followed by natural cooling. The drying rate, moisture removal, and temperature of the rice were determined. The rice temperatures after the IR heating were in the range of 35.9 degrees C to 71.4 degrees C. The heating and drying rates decreased with the increase of bed thickness. Up to 2.2% of moisture was removed during natural cooling after tempering, without additional energy input. IR heating under tested conditions did not have adverse effects on rice sensory and milling quality, including total rice yield, head rice yield, and degree of milling of the dried rice. We concluded that a high heating rate, fast drying, and good rice quality can be achieved by IR heating of rough rice to about 60 degrees C followed by tempering and natural cooling with a tested bed thickness up to 10 mm.

AB Options for odor control from tunnel-ventilated swine barns are limited. Automated scrapers have proven successful for reducing odor at free-stall dairies and for reducing hydrogen sulfide at a research-scale swine facility, but their effectiveness for reducing odor in commercial tunnel-ventilated swine barns has never been evaluated. A research project was conducted to compare odor concentrations in exhaust of traditional flush barns and barns equipped with automated scrapers. The study was conducted at commercial tunnel-ventilated swine barns owned by Premium Standard Farms LLC in northwest Missouri. Odor samples were collected from the barn exhaust in Tedlar bags and analyzed by trained human panelists using triangular forced-choice olfactometry. Total reduced sulfur (TRS) concentrations were measured with a portable Jerome meter, and volatile organic compounds (VOCs) were sampled in sorbent tubes and analyzed by gas chromatography/mass spectrometry. Mean odor concentrations (dilutions to threshold, DT) were 75.6% lower in exhaust from scraper barns (DT = 941) than flush barns (DT = 3860) (p < 0.001). Mean recognition thresholds (RT) were 76.4% lower in exhaust from scraper barns (RT = 494) than flush barns (RT = 2095) (p < 0.001). TRS concentrations averaged 1.59 and 0.16 ppm in flush and scraper barns, respectively, for an 89.9% difference (p = 0.029). Hedonic tone and intensity were statistically similar for flush and scraper barns. Odor was positively correlated with TRS in flush barns, while in scraper barns odor was positively correlated with butyric acid, 4-ethylphenol, indole, and skatole. Odor concentrations were significantly greater during flush than between flush events (p = 0.002), but there was no difference in mean odor concentrations during scrape and between scrape events (p = 0.20). These results show that scraper barns are a practical alternative for the control of odor emitted from tunnel-ventilated swine barns.

TI CALCULATION OF EFFECTIVE GAS FLUX FROM SOIL FOLLOWING BAND APPLICATION

AB Greenhouse gases are emitted following application of manure and nitrogen-containing fertilizers to soil. Manure and fertilizers are often applied in subsurface bands in the soil, or in bands on the soil surface. This article presents a method that has been developed for calculating the effective gas flux for a multiple-band area to which manure or fertilizer has been applied in bands. The method has been developed for circular and rectangular flux chambers. In analyzing the method, a combination of CO(2) gas fluxes from a field experiment that gave a relatively low whole-plot effective flux and a combination that gave a relatively high whole-plot effective flux were used. For the lower-end flux situation, when the dimension of the flux chamber in the direction perpendicular to the band is considerably less than the band spacing, if the flux in a chamber that is centered on a band is assumed to be the whole-plot effective flux, then this assumption would overestimate the actual whole-plot effective flux by a considerable amount. The error of this type of assumption is reduced for the higher-end flux situation, regardless of flux chamber dimensions, and is reduced when the lower-end flux situation occurs and the dimension of the flux chamber in the direction perpendicular to the band is intermediate to nearly as large as the band spacing. The method in useful in calculating effective gas fluxes for whole plots to which manure or fertilizer has been band-applied.

AB Advanced remote sensing technologies provide researchers an innovative way to collect spatial data in precision agriculture. Sensor information and spatial analysis together allow for a detailed understanding of the spatial complexity of a field and its crop. The objective of the study was to describe field variability in the normalized difference vegetation index (NDVI) and characterize the spatial structure of NDVI data by geostatistical variogram analysis. Data sets at three different sampling densities were investigated and compared to characterize NDVI variation within the specified study area. Variograms were computed by Matheron's method of moments (MoM) estimator and fitted by theoretical models. The fitted spherical model was determined to be the best model for the data analysis in the study. The range of spatial dependence of the NDVI data was 40 m for a sampling area of 4 m x 3 m. Knowing the amount of remotely sensed data needed to characterize the spatial variation of the field with NDVI allows us to save sampling costs and prescribe site-specific nitrogen and other agrichemical applications.

SO TRANSACTIONS OF THE ASABE

DT Article
DE Entomology; Instrumentation; Radio frequency; Transponder
ID FLIGHT; TAGS; DESIGN
AB Monitoring technologies are needed to track insects and gain a better understanding of their behavior, population, migration, and movement. A portable microwave harmonic-radar tracking system that utilizes antenna miniaturization techniques was investigated to achieve this goal. The system mainly consists of a compact radar unit, a hand-held transmitter/receiver (Tx/Rx) patch antenna array panel, and a passive radio frequency (RF) transponder. The system transmits a signal at 5.882 GHz and receives returned signals in the 11.764 GHz band. The RF transponder to be mounted on insects is a 9.63 mm x 9.63 mm flat plane weighing 6 mg. Tests were conducted to optimize the horizontal and vertical tracking ranges of the system by measurement of radio frequency signal strength from the transponder in open terrain, inside tree canopies, and underground at different tracking angles. In open terrain, a directional tracking range of over 60 m was achieved. However, obstructions from tree canopies and the high water content of leaves severely weakened the microwave signal strength and restricted the tracking range to below 20 m. To obtain maximum signal strength, the Tx/Rx antenna panel and the transponder must be in a mutually clear line of sight and their angles must be maintained within a 10 degrees range. However, the use of harmonic radar technology to develop a portable tracking system with a small insect-borne transponder currently poses insurmountable challenges for antenna design due to the very stringent requirements to accommodate the tracking range, the transponder size and mass, and the methods used to attach the transponders to insects.

AB Cellular and subcellular mechanisms involved in tissue responses to larval and adult lungworms (Protostrongylidae) were respectively explored through experimental and natural infections in molluscan intermediate (Xeropicta candacharica) and ruminant definitive hosts (Ovis aries). Reaction to developing larval stages in the gastropod is manifested as cellular infiltration involving lymphocytes and macrophages into the infected tissue, which restricts damage and may result in destruction and elimination of parasites from the intermediate host. Variations in the patterns of localization for infective third-stage larvae in the foot tissue of the intermediate host are described. In the definitive host, evaluation of lung tissue by histology and transmission electron microscopy revealed the activation of lymphocytic and monocytic-macrophage systems. An intensive fibroblastic reaction in the lung parenchyma results in formation of connective-tissue capsules around helminths and more broadly demarcates zones of infected tissue.

AB The cytochrome c oxidase subunit I (COI) gene of the mitochondrial DNA was sequenced in eight holocyclic monoecious aphids (Hemiptera: Aphididae) that occur on wheat, Triticum aestivum L.; barley, Hordeum vulgare L.; oat, Avena sativa L.; and sorghum, Sorghum bicolor (L.) Moench in the United States. The first 640 bp of the 5' end were considered as a DNA barcoding technique for species identification. DNA barcoding successfully differentiated Schizaphis graminum (Rondani), Diruaphis noxia (Kurdjumov), Diruaphis tritici (Gillette), Diruaphis frequens (Walker), Diruaphis mexicana (McVicar Baker), Sipha flava (Forbes), Sipha elegans del Guercio, and Sitobion avenae (F.). In addition to the above-mentioned monoecious species, the common cereal aphids Rhopalosiphum padi (L.) and Rhopalosiphum maidis (Fitch) were included and successfully differentiated. DNA barcoding is a reliable alternative to traditional morphology in the identification of cereal aphids and their various life stages and morphs, including eggs. The application of DNA barcoding to aphid eggs found on grasses will be able to confirm whether D. noxia is now reproducing sexually in the United States after 20 yr of asexual reproduction.

AB The koinobiont endoparasitoid Diaphorencyrtus aligarhensis (Shafee, Alam & Agarwal) (Hymenoptera: Encyrtidae) is an imported biological control agent being released in Florida against the Asian citrus psyllid, Diaphorina citri Kuwayama (Hemiptera: Psyllidae). The eggs and early larvae were found free floating within the hemocoel. Larvae were soft bodied with no observable hairs, bristles, or external appendages, such as anal vesicles, in any instar. By the third instar, larvae had begun attaching to nymphal tissues by anal secretions that provided a means of orienting within the host nymph. The penultimate and last-instar larvae were found with their posterior anchored in the head-thoracic region of the host with their head oriented toward the posterior of the host nymph. Before the beginning of the prepupal stage, the host nymph was turned into a mummy and glued to a plant surface, apparently requiring some secretions from the wasp larva. Development from oviposition to adult eclosion of D. aligarhensis took approximate to 16 d at 25 degrees C when oviposition occurred in second-through early fourth-instar nymphs, although this time was shortened by 4 d (25%) when the wasps oviposited in mid-fourth-instar D. citri nymphs. This reduction in developmental time did not affect wasp fertility or life span and may offer a significant approach to improved rearing of this wasp for augmentative releases to control the Asian citrus psyllid.

AB The understanding of fall armyworm, Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae), physiology has frequently suffered from discrepancies between different studies. One potential source of error is the assumption that laboratory colonies are sufficiently representative of wild populations that their biological parameters can be generalized. This is unlikely to be valid if the phenotype in question exhibits extensive genetic variation in the natural population, in which case laboratory lines can only be expected to contain a subset of the relevant genotypes. Here, I investigated whether this is a concern for experiments measuring larval developmental rate, a parameter frequently used to assess the relative resistance of different plant lines to fall armyworm herbivory. To estimate the genetic variation in this phenotype a simple selection experiment was performed to determine whether significantly different developmental rates could be isolated from inbred laboratory colonies representing the fall armyworm subgroup (rice-strain) that is the primary pest of pasture grasses. The results indicate that a strong genetic component influences larval development. Therefore, the average larval duration of the test population for a given treatment will depend on its genotypic composition that could vary significantly with different colonies. The implications of these findings on designing and evaluating feeding studies for fall armyworm are discussed.

Strong evidence is found to support the hypothesis that TFP converges to a steady state. Health care supply in rural areas and research spillovers from other states and from nonagricultural sectors are found to have significant impacts on the productivity growth rate in both the short and the long run. These results suggest a richer set of opportunities for policy makers to enhance productivity growth than previously considered.

AB There is a realization that managed forests and other natural areas in the landscape matrix can and must make significant contributions to biodiversity conservation. Often, however, there are no consistent baseline vegetation or wildlife data for assessing the status of biodiversity elements across protected and managed areas for conservation planning, nor is there a rapid and efficient means to acquire those data. We used a unified vegetation classification and simple animal sampling design to describe the patterns of abundance of selected mammals as indicator, or characteristic, species in different vegetation types and protected areas vs. managed forest units in the Terai Conservation Area (TCA) in northern Uttar Pradesh state, India. We quantified the relative abundance of 15 mammals of conservation concern from dung counts in vegetation sampling plots within 122 sample patches in 13 vegetation types and 4 management units. Assemblages of species differed both among vegetation types and among management units. Species assemblages in the two protected areas differed strongly from those in two managed forests. Grasslands in protected areas were the most species diverse among vegetation types and had several indicator species. Protected forests were dominated by chital (Axis axis) and nilgai (Boselaphus tragocamelus) in a second species group. A third species group in open grasslands and savannas in managed forests was characterized by cattle (Bos taurus) and Indian hare (Lepus nigricollis). Protected areas clearly are the core conservation area of the TCA for their relatively high habitat value and species diversity, and their protected status minimizes human disturbance. Impacts of human use are high in managed forests, indicating their compromised value for biodiversity conservation. Our simple assessment methodology gives managers a simple way to assess the status of important mammals across landscape conservation units.

AB The effectiveness of extracting free and bound phenolic compounds and antioxidant activities from air-classified corn bran was evaluated by various extracting methods. Free phenolic contents and antioxidant activities decreased significantly with increasing particle sizes for all methods used in the study. Also, the oil, protein, and ash contents were noticeably decreased with increasing particle sizes. By contrast, bound phenolic content and antioxidant activities increased with increasing particle sizes. Free phenolic contents were much lower than those of bound phenolic contents for the same fraction. The free antioxidant activities were similar to bound antioxidant activities for the same fraction. It suggests that phenolic compounds may not exhibit antioxidant activity, and some antioxidant activities were not extractable or released during alkaline extraction. Considerable higher free antioxidant activities were found in both direct and double extractions when compared to the single neutral extraction using samples <30 mu m. Similar free antioxidant activities were observed for directed extraction and double extraction. For corn bran fractions, the direct method may be suitable for free phenolic content and antioxidant activity, while the sequential method may be proper for bound phenolic content and antioxidant activity.

TI Determining Weight and Moisture Properties of Sound and Fusarium-Damaged
Single Wheat Kernels by Near-Infrared Spectroscopy
SO CEREAL CHEMISTRY

ID RED WINTER-WHEAT; QUALITY CHARACTERISTICS; PREDICTION; SCAB
AB Single kernel moisture content (MC) is important in the measurement of other quality traits in single kernels because many traits are expressed on a dry weight basis. MC also affects viability, storage quality, and price. Also, if near-infrared (NIR) spectroscopy is used to measure grain traits, the influence of water must be accounted for because water is a strong absorber throughout the NIR region. The feasibility of measurement of MC, fresh weight, dry weight, and water mass of single wheat kernels with or without Fusarium damage was investigated using two wheat cultivars with three visually selected classes of kernels with Fusarium damage and a range of MC. Calibration models were developed either from all kernel classes or from only undamaged kernels of one cultivar that were then validated using all spectra of the other cultivar. A calibration model developed for MC when using all kernels from the wheat cultivar Jagalene had a coefficient of determination (R(2)) of 0.77 and standard error of cross validation (SECV) of 1.03%. This model predicted the MC of the wheat cultivar 2137 with R(2) of 0.81 and a standard error of prediction (SEP) of 1.02% and RPD of 2.2. Calibration models developed using all kernels from both cultivars predicted MC, fresh weight, dry weight, or water mass in kernels better than models that used only undamaged kernels from both cultivars. Single kernel water mass was more accurately estimated using the actual fresh weight of kernels and MC predicted by calibrations that used all kernels or undamaged kernels. The necessity for evaluating and expressing constituent levels in single kernels on a mass/kernel basis rather than a percentage basis was elaborated. The need to overcome the effects of kernel size and water mass on single kernel spectra before using in calibration model development was also high-lighted.

AB Long-grain nonparboiled, long-grain parboiled, and American basmati-type brown rice were bombarded with parboiled rice flour particles to create microperforations on the water-resistant outer layer of the kernels. These microperforations in the treated rice significantly increased the rate of hydration. Optimum conditions to produce microperforations without removal of the bran included air pressure maintained at 413 kPa and a parboiled rice flour average particle size of 124 mu m. The optimum blasting time was 40-60 sec, depending on the type of rice. The relative hardness of the fully cooked flour-blasted rice was the same at half the cooking time of the untreated brown rice but % water absorption of the untreated flour-blasted brown rice was higher because it required longer time to cook. Overall, untreated brown rice was approximate to 4.7% higher in % water absorption due to longer cooking time in comparison with the treated counterpart. The blasting treatment resulted in shorter cooking time and firmer and less gummy cooked rice as compared to freshly cooked untreated brown rice.

ID FREE FATTY-ACID; MILLED RICE; BRAN
AB Brown rice was blasted with rice flour rather than sand in a sand blaster to make microperforations so that water could easily penetrate the brown rice endosperm and cook the rice in a shorter time. The flour-blasted American Basmati brown rice, long-grain brown rice, and parboiled long-grain brown rice samples were stored in Ziploc storage bags under atmospheric conditions and in vacuum-packed bags. They were periodically tested for over 10 months for changes in water absorption, free fatty acid (FFA), peroxide value (POV), viscosity changes of flour using the Rapid Visco Analyser (RVA), and texture of whole cooked kernel using a texture analyzer during cooking. Flour-blasted brown rice absorbed less water but needed less cooking time than its counterpart that was not flour-blasted. There was an increase in FFA, POV, peak viscosity (PV), final viscosity (FV), breakdown viscosity (BD), and setback viscosity (SB) during storage of flour-blasted brown rice for 300 days, but no change was observed in texture (hardness, gumminess) and water absorption. The combined coefficient of correlation (including all types of rice) between FFA and FV is r = 0.86 and between FFA and SB is r = 0.90 at P < 0.0001.

AB Quality and agronomic effects of three transgenic high molecular weight glutenin subunit (HMW-GS) events were characterized in advanced-generation breeding lines of hard winter wheat (Triticum aestivum L.) in three Nebraska crop years. Two of the transgenic events studied, Dy10-E and B52a-6, overexpress HMW-GS 1Dy10, while the third event, Dx5 +Dy10-H, overexpresses HMW-GS 1Dx5 and, to a much lesser extent, 1Dy10. In addition, novel proteins possessing solubility characteristics defined as HMW-GS were present in Dx5+Dy10-H and B52a-6. Average grain yield of lines derived from the three transgenic events was statistically lower than that of a group of control cultivars and advanced breeding lines, but not lower than the mean values of respective nontransgenic siblings. Grain hardness was influenced by one of the events. Dx5+Dy10-H produced harder kernels than controls, its nontransgenic siblings, and the two additional transgenic events. All three events produced doughs with unusual mixing properties, although not likely to be directly useful in commercial applications. As a consequence, loaf volumes were depressed to variable degrees by the three events. The results indicated that overexpression of HMW-GS could eventually lead to improved breadmaking quality by optimizing the level of overexpression or by development and characterization of additional events.

AB The objective of this research was to compare the efficacy of potassium bromate with that of ozone treatment in wheat flour oxidation for breadmaking. In the first experiment, flour was treated with ozone at 1,500 ppm for 2, 4.5, 9, and 18 min. In the second experiment, flour was fully treated with ozone at 1,500 ppm for 45 min and then blended with control flour at concentrations of 10-30% (w/w). Flour became whiter and less yellow as ozonation time increased when compared to control flour. Size-exclusion HPLC detected an increase in SDS buffer insoluble polymeric proteins in flour exposed to ozone. Bread made from flour treated with ozone for 2-4.5 min and bread that was made from flour blended with fully zonated flour at 5 and 10% (w/w) was not significantly different for specific volume when compared with bread made with flour containing potassium bromate. Bread made from flour treated with ozone for 2, 4.5, and 9 min had a greater number of cells in crumb with larger loaf volumes than control flour. Results indicate that ozone treatment of flour could eliminate the need for potassium bromate in breadmaking.

AB Bahiagrass (Paspalum notatum Flugge) is the major pasture forage in the southern Gulf Coast, USA. A bahiagrass selection breeding program has been ongoing since 1960 at the Coastal Plain Experiment Station at Tifton, Georgia, USA, to increase forage yield in Pensacola (P. notatum var. sanese) bahiagrass. However, the impact of selecting for forage yield on forage nutritional quality is unknown. Forage quality was evaluated on four Pensacola derived selection cycles (C) of bahiagrass [C0 (Pensacola), C4, C9 (Tifton 9), and C23]. A total of 175 plants per cycle were grown. Forage from individual 1-year-old plants was harvested by hand on 3 October and again on 15 November 2000. The samples were dried, ground, and analyzed using internally calibrated near-infrared reflectance spectroscopy (NIRS) for dry matter (DM), in vitro-digestible organic matter (IVDOM), neutral detergent fiber (NDF), and crude protein (CP). Cycle means (g kg-1 DM basis combined over both harvest dates) for IVDOM, NDF, and CP were 497, 810, and 142; 503, 797, and 137; 528, 787, and 132; and 520, 785, and 129 for C0, C4, C9, and C23, respectively. The average IVDOM of C4 was greater than for C0 (P = 0.03) and that for C9 was greater than for C4 (P 0.001). Results indicated that forage quality also increased with advancing selection cycles for increasing yield.

AB Earthworms can influence incorporation of animal manures and composts into the soil. As this activity can decrease the potential for phosphorus (P) loss in runoff and increase plant nutrient availability, we evaluated the effect of manure application on earthworm activity. Earthworm activity (as indicated by surface casts of Lumbricus terrestris) and soil P distribution were determined as a function of superphosphate, manure, and compost (dairy and poultry) applied at rates of 0, 50, 100, and 200 kg P ha-1 yr-1. Surface earthworm cast production was greatest in the wet and warm months of May to July. For instance, average annual cast production was 24,520 and 13,760 kg ha-1 with respective applications of dairy manure and compost (100 kg P ha-1) compared with 9,090 kg ha-1 when superphosphate was added. This increased activity was accompanied by lower Mehlich 3 P (130 mg kg-1) at the surface (0-5 cm) of soils treated with 100 kg P ha-1 yr-1 dairy manure than those treated with superphosphate (210 mg kg-1) but greater concentrations at 5 to 10 cm deep (95 and 50 mg kg-1, respectively). While there may have been greater downward movement of organic P added in manure and compost, the stimulation of L. terrestris activity by application of manure or compost has the potential to redistribute surface-applied P within the soil profile to a greater extent than when equivalent applications of P are made in the form of inorganic fertilizer.

ID CRIME; TIME
AB In criminology, it is well understood that indicators of urban decay, such as abandoned buildings littered with broken windows, provide criminals with signals identifying neighborhoods with lower crime detection and apprehension rates than better maintained neighborhoods. Whether it is the resident population's sense of apathy, lack of civic pride, or fear of confrontation that causes criminals to perceive an easy mark, it nevertheless emboldens them to strike. Previous research of wildland arson hints that broken windows (e.g., areas of criminal activity) are partly responsible for arson outbreaks within the wildland-urban interface. We model the incidence of wildland and non-wildland arson ignitions in Michigan from 2001 to 2005 as a function of constructed Broken Windows indices. Our results suggest that crime prevention and urban revitalization programs may be as valuable as fire suppression, fuels management, and law enforcement in limiting incidence and the damage from both wildland and non-wildland arson.

ID ATMOSPHERIC CO2 ENRICHMENT
AB Root-soil relationships are pivotal to understanding crop growth and function in a changing environment. Plant root systems are difficult to measure and remain understudied relative to above ground responses. High variation among field samples often leads to non-significance when standard statistics are employed. The adaptive neuro-fuzzy inference system (ANFIS) has been applied in many agricultural and environmental fields and may represent a viable means for dealing with complexities of root distribution in soil. We applied this method to vertical and horizontal root distribution data collected from a potato (Solanum tuberosum L.) cropping system grown under ambient and elevated levels of atmospheric CO(2). The lack of a CO(2) effect on root length or dry mass densities was most likely due to the low growing season temperature limiting root growth in this subarctic system. At all CO(2) levels, potato roots were concentrated near row centre, particularly in the upper soil profile. Simulations indicated that ANFIS gave plausible results, indicating it offers a viable alternative to more traditional statistical techniques for evaluation of complex root distribution patterns.

TI Postharvest losses and waste in developed and less developed countries:
opportunities to improve resource use
SO JOURNAL OF AGRICULTURAL SCIENCE
LA English
DT Article
AB This review compares and contrasts postharvest food losses (PHLs) and waste in developed countries (especially the USA and the UK) with those in less developed countries (LDCs), especially the case of cereals in sub-Saharan Africa. Reducing food losses oilers an important way of increasing food availability without requiring additional production resources, and in LDCs it can contribute to rural development and poverty reduction by improving agribusiness livelihoods. The critical factors governing PHLs and food waste are mostly after the farm gate in developed countries but before the farm gate in LDCs. In the foreseeable future (e.g. up to 2030), the main drivers for reducing PHLs differ: in the developed world, they include consumer education campaigns, carefully targeted taxation and private and public sector partnerships sharing the responsibility for loss reduction. The LDCs' drivers include more widespread education of farmers in the causes of PHLs; better infrastructure to connect smallholders to markets; more effective value chains that provide sufficient financial incentives at the producer level; opportunities to adopt collective marketing and better technologies supported by access to microcredit; and the public and private sectors sharing the investment costs and risks in market-orientated interventions.

AB The National Environmental Policy Act (NEPA) and its accompanying regulations provide a spectrum of alternative analytical pathways for federal agencies proposing major actions that might significantly impact the human environment. Although guidance from the President's Council on Environmental Quality suggests the decision to develop an environmental impact statement (EIS), which requires the most rigorous level of analysis, should be based on the likelihood of significant environmental impacts, findings from an Internet survey with US Forest Service project leaders suggest that the decision may more commonly be. based on process-related risks, including the threat of litigation, perceived defensibility in court, and the level of public and political interest in the agency's proposed action. An analysis of judicial decisions in NEPA-related litigation reveals that EISs do not appear to be more defensible than environmental assessments in the courts, suggesting that current decisionmaking about NEPA documentation may be misguided, leading to unnecessary project expenditures and delays.

AB In the sawmill sector of the forest products industry, the clustering of mills and wide variation in forest stocking and ownership result in sawlog markets that are complex and spatially differentiated. Despite the inherent spatial attributes of markets for stumpage and logs, few studies have used geospatial methods to examine wood procurement in detail across political boundaries. This article provides a visual, representation of wood procurement pressure across the Northern Forest region of the northeastern United States based on a spatial analysis of woodshed maps provided by 273 sawmills in the United States and Canada. The analysis also includes the predicted woodsheds of 280 nonrespondent mills, which were modeled based on mill characteristics and location. In general, maps emphasize the magnitude of softwood procurement on industrial and investment-oriented forestlands in northern Maine, but also highlight distinct spatial procurement patterns in New York, Vermont, and New Hampshire. Sensitivity analyses of woodshed boundary uncertainty suggest that procurement pressure in existing hotspots will intensify if procurement range is restricted by high transportation costs. The methods used to visualize resource procurement in this study have the potential to benefit a broad range of stakeholders including industry, policymakers, and landowners.

AB An important objective of forest health research is that it is applicable to and used by end users. A survey, interviews, and two case studies determined how to best transfer research to US Forest Service end users in the Rocky Mountain Region. The survey indicated research information was most often found via the Internet, peer-to-peer interactions, publications, specialist visits, and field days. However, the most preferred methods were site visits by specialists, field days, and peers. Interviewees indicated that increased workloads and decreased budgets restricted them from staying current with research findings. Case studies found transferring findings directly from a researcher can be inefficient while using boundary spanners reduces researchers' efforts on technology transfer. To be better disseminated to end users, research findings should use face-to-face media, be easy to interpret and quick to use, and build on or establish trust between researchers, boundary spanners, and end users.

AB Species in which female choice is not strongly shaped by male-controlled resources present a challenge to sexual selection research, because it is typically difficult to identify the male phenotypic cues used in female mate selection or the fitness benefits accruing from such selection. In such species, mate selection is presumably based on direct benefits associated with sperm quantity or quality and/or indirect benefits relating to the viability or mating probability of the progeny. Across animal taxa in general, male age has received considerable attention as a potential indicator of these fitness benefits, and the importance of male age in affecting female choice and fitness has been investigated in various insect species with highly variable results. The present study examined whether females of the Mediterranean fruit fly (medfly), Ceratitis capitata (Wied.), a lek-forming species, discriminate among potential mates on the basis of male age and whether this selectivity results in fitness benefits to the females. Both young (10 days old) and old (40 days old) females were offered males from two groups differing in age by 10, 20, or 30 days. Young females mated randomly when the age difference between the younger and older males was 10 days but mated preferentially with the younger males when the age difference was 20 or 30 days. Old females did not discriminate among males of different ages. Although young females showed mate selectivity, we found no differences in fecundity, fertility, or larval viability between young females mated to 10 versus 40 day old males.

ID ALUMINUM TOLERANCE; MECHANISMS; EXUDATION; SOILS
AB Little is known about the adaptability of rambutan (Nephelium lappaceum) to highly acidic soils rich in aluminum (Al). A 2-yr field study was conducted to determine the effects of various levels of soil Al on dry matter production, plant growth, and nutrient concentration in the leaves of four cultivars of rambutan. Cultivars and the cultivar x year interaction were not statistically significant for most variables measured in the study. Total, leaf, petiole, stem and root dry weights significantly increased at soil Al concentrations ranging from 0.67 cmol kg-1 to 11.0 cmol kg-1. At this range of soil Al, the concentrations of Al and manganese (Mn) in leaf tissue declined sharply. The results of this study demonstrate that rambutan is highly tolerant to acid soils and that tolerance may involve an Al- and Mn- exclusion mechanism.

ID SURVIVAL; GROWTH; DESCRIBE; PH
AB Agricultural land application of biosolids is an environmentally sound method for recycling stabilized sludge generated during wastewater treatment processes. Meeting regulatory microbial criteria remains an expensive and time consuming process, especially when testing is performed prematurely and requires re-testing. The objective of this study was to determine how well neural network monitoring predicted microbial survival in response to changes in temperature and moisture content of biosolids under laboratory conditions. The backpropagation feed-forward neural network method showed superior performance in predicting the microbial inactivation of fecal coliforms (R(2) = 0.95) as a function of temperature and moisture relative to linear-regression models. Although mathematical modeling may not be a sufficient substitute for microbial testing, it may be a useful support tool to optimize the timing of testing for microbial quality designation of biosolids. Further studies involving prediction of specific pathogen levels (Salmonella sp., enteric virus, and viable helminth ova), while incorporating a variety of sludge matrices and environmental parameters, are needed to help determine the full advantages of ANN modeling.

AB The U.S. General Land Office land surveys document trees present during European settlement. However, use of these surveys for calculating historical forest density and other derived metrics is limited by uncertainty about the performance of plotless density estimators under a range of conditions. Therefore, we tested two plotless density estimators, developed by Morisita and Pollard, for two, three, and four trees per survey point under simulated ranges of tree densities, non-uniform densities, and different tree spatial distributions. Based on these results, we developed estimator corrections and determined number of survey points needed for reliable density estimates. The Morisita estimator was accurate for densities ranging from 5 to 1,000 trees per unit area, non-uniform densities, random and regular spatial distribution, and outperformed the Pollard estimator. Estimators using points with two or three trees did need a simple correction to account for overestimation. Likewise, for clustered distributions, depending on the number of trees per survey point and the amount of clustering, there should be adjustment for a range of under and overestimation. Sample sizes for survey points with three or four trees should be at least 200 survey points, and 1,000 survey points will have density estimates within +/- 10% tolerance range of actual density. For survey points with two trees, the minimum sample size should be 600 survey points, and 2,000 survey points should be the target value. These results provide guidelines for researchers to improve density estimates of historical forests.

AB This paper examines the theoretical intersection of place attachment and community through a study of the place attachment of residents who live, work, and play in a tourism-dependent community. Using a qualitative photo-elicitation technique best described as "resident employed photography," we asked 25 residents of Seward, Alaska, to share images and stories of important places in and around their local community. The findings suggest that place and community are intertwined, as evidenced by the use of community as a frame of reference for describing nearly every example of attachment to place. This suggests that place attachment can serve as a factor in the development "of" community, defined as a heightened engagement in collective actions that help people meet their day-to-day needs. It could also influence one's development "in" community, directing the behaviors that affect how people both participate in communities and seek to change their position within them.

AB P>The cauliflower (Brassica oleracea var. botrytis) Orange (Or) gene affects plant growth and development in addition to conferring beta-carotene accumulation. This study was undertaken to investigate the molecular basis for the effects of the Or gene mutation in on plant growth.
The OR protein was found to interact with cauliflower and Arabidopsis eukaryotic release factor 1-2 (eRF1-2), a member of the eRF1 family, by yeast two-hybrid analysis and by bimolecular fluorescence complementation (BiFC) assay. Concomitantly, the Or mutant showed reduced expression of the BoeRF1 family genes. Transgenic cauliflower plants with suppressed expression of BoeRF1-2 and BoeRF1-3 were generated by RNA interference.
Like the Or mutant, the BoeRF1 RNAi lines showed increased elongation of the leaf petiole. This long-petiole phenotype was largely caused by enhanced cell elongation, which resulted from increased cell length and elevated expression of genes involved in cell-wall loosening.
These findings demonstrate that the cauliflower Or gene controls petiole elongation by suppressing the expression of eRF1 genes, and provide new insights into the molecular mechanism of leaf petiole regulation.

DIET SELECTION; VARIED DIETS; STOCKING
AB Rotational grazing systems (RGS) are often implemented to alleviate undesirable selective grazing by livestock. At both fine and coarse scales, livestock selectively graze individual plants, patches, communities, and landscapes. Smaller pastures, increased stocking density, and rotation allow managers to constrain livestock movement and determine season and frequency of grazing, potentially limiting selectivity and preventing repeated grazing of preferred plants. However, in arid and semi-arid rangelands, forage growth is limited primarily by precipitation rather than defoliation frequency. When soil moisture is adequate, forage is abundant and defoliation levels are typically low, and repeated, intensive defoliation of preferred plants is less likely than in more mesic areas where more consistent precipitation and soil moisture storage allows animals to establish and maintain spatial hierarchies of grazing patterns. Many southwestern rangelands contain diverse vegetation, which provides quality forage during different times of the year. These spatial and temporal patterns of forage distribution may not be amenable to manipulation with RGS. Tracking data show that livestock often alternate among locations within pasture boundaries and can opportunistically exploit areas with higher quality forage when they are available. Higher stock densities combined with higher stocking rates can increase livestock use of less preferred areas, but overall distribution patterns of intensive-rotational and extensive grazing systems are often comparable at similar stocking rates and distances from water. Management that ensures that grazing of riparian areas does not occur during the critical late summer period may be more beneficial than RGS that periodically defers livestock use throughout the grazing season. In arid and semi-arid shrublands, timely adjustments to animal numbers and practices that improve grazing distribution at regional and landscape scales are more likely to be effective in maintaining or improving rangeland health than fencing and RGS.

AB Complete rest or grazing deferment is a general recommendation to encourage vegetative recovery following fire in the western United States. However, effects of grazing deferments on animal performance have not been determined. Prescribed fires were individually applied to nine separate, 1.5-ha pastures each year (2006 and 2007) for a total of 18 pastures. Grazing was deferred until spring (16 May), early summer (19 June), or late summer (1 August) the growing season after fire. At the end of each deferment, a 70-d (2007) or 41-d (2008) grazing period was initiated. Stocking rates were consistent between treatments within year, but were adjusted between years to achieve the targeted residual biomass of approximately 300 kg . ha(-1). Diet quality was assessed approximately every 15 d throughout each grazing period (three pastures . period(-1)) via collection of rumen extrusa throughout the 2-yr study. Ewe body weight was measured on and off-test for each grazing period. Diet extrusa samples for in vitro organic matter disappearance was less (P = 0.03) for late summer than early summer grazing periods and equal to the spring period (62.9, 64.6, and 61.0 +/- 0.90%, respectively for spring, early summer, and late summer grazing periods). In vitro neutral detergent fiber disappearance decreased (P = 0.01) by 10.6 percentage units from early grazing to late grazing period in 2007, whereas no differences were observed in 2008. Ewe average daily gain did not differ between spring and early summer grazing periods and were greater (P = 0.03) than the negligible body weight gains of the late summer grazing period. Total gain was 10.9 kg . ha(-1) greater in 2008, and a quadratic response was measured for grazing period in 2007. Results indicate that deferment until early summer may be preferable so that stocking rates can be more accurately determined and animal performance is not diminished.

AB Fire is an important process in many ecosystems, especially grasslands. However, documentation of plant community and soil environment responses to fire is limited for semiarid grasslands relative to that for mesic grasslands. Replicated summer fire research is lacking but necessary because summer is the natural fire season and the period of most wildfires in the western United States. We evaluated summer fire effects on soil temperature, soil moisture, aboveground biomass, root biomass, and functional group composition for 2 yr in semiarid C(3)-dominated northern Great Plains. Following pre-treatment measures, four 0.75-ha sites were burned during August for comparison with nonburned sites, and the experiment was repeated the next year on adjacent sites to assess weather effects. Soils were about 0.5 degrees C cooler on burned sites in the first experiment and similar in the second. Burned sites were consistently 1% drier than nonburned sites. Litter was reduced by fire but did not account for changes in soil moisture because differences occurred before the growing season. Current-year aboveground biomass and root biomass were similar between treatments, indicating productivity was resistant to summer fire. Perennial C(3) grasses increased in dominance because of positive biomass responses to fire for all but the bunchgrass, Hesperostipa comata, and a reduction of annual grasses. Perennial C(4) grasses were unaffected by summer fire. H. comata was resilient, with biomass on burned sites equaling nonburned sites the second growing season. Biomass was more responsive to precipitation than fire, and the fire-induced changes in species composition suggest exclusion of fire may be a greater disturbance than summer fire.

AB Broadleaf herbicides are commonly used in rangelands to suppress exotic weeds and release native communities from negative impacts of invasion. However, few studies have comprehensively evaluated treatment effects on differing community components across a gradient of initial invasion levels. We conducted a 6-yr experiment within grasslands of western Montana to measure local-scale effects of a broadcast application of picloram on 1) cover of the target invader, spotted knapweed (Centaurea stoebe L.), 2) prevalence of native functional groups, and 3) the secondary invader cheatgrass (Bromus tectorum L.) at differing initial levels of knapweed invasion,. Treatment effectively suppressed knapweed, with cover in treated vs. control plots reduced by > 60% in the sixth posttreatment year. Treatment also appeared to alleviate knapweed's impacts on native perennial grasses, but only at the highest initial level of invasion, where cover of this group increased by > 30% in treated vs. control plots to equal levels associated with noninvaded plots. In some cases, treatment appeared to exacerbate knapweed's impacts on native forbs. At the no-invasion level, perennial forb cover declined by > 20% in treated vs. control plots to match values associated with moderate or high levels of invasion, but these treatment effects were minimal at the latter invasion levels. Across initial invasion levels, species richness of perennial and/or annual forbs declined by > 20% in treated vs. control plots. Treatment also promoted increases in cheatgrass cover, although differences between treated and control plots were relatively small by the sixth posttreatment year. Overall, effects of picloram application depended on initial levels of knapweed invasion, largely due to the varying strength of release effects. Selective treatment of invaded patches vs. broadcast applications would reduce side effects of broadleaf herbicide application and increase compatibility with other management measures designed to improve rangeland conditions and restore grassland communities.

AB Long-term information on the effects of managed grazing versus excluded grazing effects on vegetation composition of desert rangelands is limited. Our study objectives were to evaluate changes in frequency of vegetation components and ecological condition scores under managed livestock grazing and excluded livestock grazing over a 38-yr period at various locations in the Chihuahuan Desert of southwestern New Mexico. Sampling occurred in 1962, 1981, 1992, 1998, 1999, and 2000. Range sites of loamy (1), gravelly (2), sandy (2), and shallow sandy (2) soils were used as replications. Black grama (Bouteloua eriopoda Tort.) was the primary vegetation component at the seven locations. Dyksterhuis quantitative climax procedures were used to determine trends in plant frequency based on a 1.91-cm loop and rangeland ecological condition scores. Frequency measures of total perennial grass, black grama, tobosa (Hilaria mutica Buckley), total shrubs, honey mesquite (Prosopis glandulosa Torr.), and other vegetation components were similar on both grazed and ungrazed treatments (P > 0.1) at the beginning and end of the study. The amount of change in rangeland ecological condition scores was the same positive increase (14%) for both grazed and ungrazed treatments. Major changes (P < 0.1) occurred within this 38-yr study period in ecological condition scores and frequency of total perennial grasses and black grama in response to annual fluctuations in precipitation. Based on this research, managed livestock grazing and excluded livestock grazing had the same long-term effects on change in plant frequency and rangeland ecological condition; thus, it appears that managed livestock grazing is sustainable on Chihuahuan desert rangelands receiving over 25 cm annual precipitation.

AB The American chestnut (Castanea dentata (Marshall) Borkh.), once a major component of eastern forests from Maine to Georgia, was functionally removed from the forest ecosystem by chestnut blight (an exotic fungal disease caused by Cryphotzectria parasitica (Murr.) Barr), first identified at the beginning of the twentieth century. Hybrid-backcross breeding programs that incorporate the blight resistance of Chinese chestnut (Castenea mollissima Blume) and Japanese chestnut (Castenea crenata Sieb. & Zuc.) into American chestnut stock show promise for achieving the blight resistance needed for species restoration. However, it is uncertain if limitations in tissue cold tolerance within current breeding programs might restrict the restoration of the species at the northern limits of American chestnut's historic range. Shoots of American chestnut and hybrid-backcross chestnut (i.e., backcross chestnut) saplings growing in two plantings in Vermont were tested during November 2006, February 2007, and April 2007 to assess their cold tolerance relative to ambient low temperatures. Shoots of two potential native competitors, northern red oak (Quercus rubra L.) and sugar maple (Acer saccharum L.), were also sampled for comparison. During the winter, American and backcross chestnuts were approximately 5 degrees C less cold tolerant than red oak and sugar maple, with a tendency for American chestnut to be more cold tolerant than the backcross chestnut. Terminal shoots of American and backcross chestnut also showed significantly more freezing damage in the field than nearby red oak and sugar maple shoots, which showed no visible injury.

AB Solanum series Conicibaccata is the second largest series in section Pet eta, containing 40 species widely distributed from southern Mexico to central Bolivia. It contains diploids (2n = 2x = 24), tetraploids (271 = 4x = 48) and hexaploids (2,1 = 6x = 72), and the limited number of species examined have been shown to be allopolyploids. Previous morphological and molecular studies using plastid DNA failed to discriminate clear species boundaries. Conserved orthologous nuclear DNA sequences (COSII) were used to compare the relationships among 72 accessions from 22 species from series Conicibaccata and 42 additional accessions from related series. The results supported previous studies showing the diploid members of series Conicibaccata to be related to other South American "clade 4" species, and showed all of the polyploids to be allopolyploids among members of clade 4 and other South American species of "clade 3" (series Piurana and related species). Low bootstrap support values and morphological similarity suggest recent origins and the need for a reduction in number of recognized species in series Conicibaccata.

AB Much of recent interest in biofuel species modeling has been for switchgrass (Panicum virgatum L.). Such modeling requires accurate simulation of light interception. We investigated the stability of the light extinction coefficient (k) in Beer's Law with data from Temple, TX; Lincoln, NE; and Elsberry, MO. Variability in k values was not related to fraction of light intercepted, time of day, or incident solar radiation. Only the magnitude of leaf area index (LAI) showed a significant impact on the k value. The mean k value (-0.37) for the 'Alamo' switchgrass data at Temple was similar to the previously published k value (-0.33) and similar to Alamo k values in Nebraska (-0.38) and Missouri (-0.31). Compared to Alamo, other switchgrass cultivars had similar k values in Nebraska but were higher in Missouri. This study gave guidance as to which factors are important for quantifying k with Beer's Law for light interception of switchgrass.

TI Planting Date Effects on Fall Forage Production of Oat Cultivars in
Wisconsin
SO AGRONOMY JOURNAL
LA English
DT Article
AB Previous research has shown that cereal-grains, such as oat (Avena sativa L.), that undergo stem elongation following late-summer establishment will likely exhibit a 2:1 advantage in forage dry matter (DM) yield before winter compared to other cereals that remain vegetative until spring. Our objectives for this project were to assess the effects of planting date on the fall forage growth of one forage-and three grain-type oat cultivars. Over a 3-yr trial, oat cultivars were planted on three target dates (15 July, 1 August, and 15 August), and subsequently evaluated over five harvest dates (15 September, 1 October, 15 October, 1 November, and 15 November) each year. For the 15 July planting date, a late-maturing forage cultivar (ForagePlus) produced maximum annual yields ranging from 4501 to 8100 kg ha(-1), and these responses were explained generally by linear (P < 0.01) and quadratic (P <= 0.03) effects of time. Accumulation of DM was superior to grain-type cultivars because ForagePlus matured slowly, and was better able to respond to sometimes erratic late-summer precipitation. With a 1 August planting date, maximum forage yields generally were similar to those observed with a mid-July planting date, but peak yield oft en was delayed by approximately 2 wk. For the 15 August planting date, maximum yields of forage DM were only 42.3, 79.9, and 20.5% of those observed following planting dates on 1 August of 2007, 2008, and 2009, respectively. Under these circumstances, the late-maturity characteristics of ForagePlus were less advantageous, oft en resulting in poorer yields throughout early harvest dates compared to grain-type cultivars.

AB Increasing interest of using broiler litter in the fall for row crops has implications for leaching losses of nutrients, particularly N. Any cultural practice that prevents nutrient losses could be agronomically beneficial and improve soil fertility. A field study was conducted in 2007 and 2008 on Leeper silty clay loam (fine, smectitic, nonacid, thermic Vertic Epiaquepts) soil to evaluate the impacts of a winter rye (Secale cereal L.) cover crop and broiler litter timing on cotton (Gossypium hirsutum L.) yield, yield components and leaching loss of NO(3)-N. Broiler litter was applied to the soil at the rates of 0, 4.5, 9, and 13.4 Mg ha(-1) in the fall and spring for both cover and no cover crop and incorporated immediately. Winter rye cover crop was planted following broiler litter application in the fall. Averaged across cropping system and broiler litter timing, cotton lint yield and yield components increased with increasing broiler litter application. Application of broiler litter at a rate >9 Mg ha(-1) was not advantageous and exceeded N need for optimum lint yield as evidenced by increasing postharvest NO(3)-N in the soil profile. In the absence of cover crop and averaged across litter rates, spring-applied broiler litter had the best agronomic response and increased lint yield by 19 and 18% compared with fall-applied litter in 2007 and 2008, respectively. Seeding a winter rye cover crop to fall-applied broiler litter did not benefit cotton lint yield and yield components but substantially reduced leaching loss of NO(3)-N.

TI Seasonal Fiber Content of Three Sugarcane Cultivars in Three Crop Cycles
on Sand and Muck Soils
SO AGRONOMY JOURNAL

ID REGISTRATION; YIELD
AB Accurate seasonal estimates of fiber are needed to maximize profits whether producing sugarcane (Saccharum spp.) for sucrose or ethanol. The main purpose of this study was to determine the effects of sample date and crop cycle on fiber content of three sugarcane cultivars growing on sand and organic (muck) soils, and secondarily to determine if fiber could be reliably estimated 1 mo before the beginning of the harvest season. From September through February, from 2007-2009, fiber content was estimated from monthly sampled stripped stalks of cultivars CP 72-2086, CP 78-1628, and CP 89-2143 growing in three replications of field plots in south Florida in the plant-cane, first-ratoon, and second-ratoon crop cycles on Pompano fine sand (siliceous, hyperthermic Typic Psammaquent) or Margate sand (Siliceous, hyperthermic Mollic Psammaquent), and Torry muck (euic, hyperthermic Typic Haplosaprist) soils. Linear increases in fiber content ranged from 0.07 to 0.28 g kg(-1) d(-1). Quadratic models usually predicted maximum fiber content from December through early January. On sand soils, the cultivar rankings were oft en similar to expectations, with fiber content of CP 78-1628 > CP 89-2143 > CP 72-2086. On the muck soil, CP 78-1628 fiber content was high, but differences between CP 72-2086 and CP 89-2143 were not consistent. For all soils, overall means were oft en not indicative of fiber status due to significant, but inconsistent interactions. Researchers should analyze fiber content whenever they analyze sucrose content, and mills should monitor fiber content daily of unique cultivar x crop cycle x soil deliveries.

AB Long-term field experiments (LTE) are ideal for predicting the influence of agricultural management on soil organic carbon (SOC) dynamics and examining biofuel crop residue removal policy questions. Our objectives were (i) to simulate SOC dynamics in LTE soils under various climates, crop rotations, fertilizer or organic amendments, and crop residue managements using the CQESTR model and (ii) to predict the potential of no-tillage (NT) management to maintain SOC stocks while removing crop residue. Classical LTEs at Champaign, IL (1876), Columbia, MO (1888), Lethbridge, AB (1911), Breton, AB (1930), and Pendleton, OR (1931) were selected for their documented history of management practice and periodic soil organic matter (SOM) measurements. Management practices ranged from monoculture to 2- or 3-yr crop rotations, manure, no fertilizer or fertilizer additions, and crop residue returned, burned, or harvested. Measured and CQESTR predicted SOC stocks under diverse agronomic practices, mean annual temperature (2.1-19 degrees C), precipitation (402-973 mm), and SOC (5.89-33.58 g SOC kg(-1)) at the LTE sites were significantly related (r(2) = 0.94, n = 186, P < 0.0001) with a slope not significantly different than 1. The simulation results indicated that the quantities of crop residue that can be sustainably harvested without jeopardizing SOC stocks were influenced by initial SOC stocks, crop rotation intensity, tillage practices, crop yield, and climate. Manure or a cover crop/intensified crop rotation under NT are options to mitigate loss of crop residue C, as using fertilizer alone is insufficient to overcome residue removal impact on SOC stocks.

TILLAGE; STRAW; DYNAMICS; REMOVAL
AB Impact of wheat (Triticum aestivum L.) and barley (Hordeum vulgare L.) straw removal from fields on soil organic carbon (SOC) is a concern. Increased animal populations and potential development of cellulosic ethanol production could increase the removal of straw from fields. This paper focuses on the effects of wheat and barley straw removal on SOC in irrigated production systems, and related the results to estimates of the minimum straw carbon inputs required to maintain soil organic carbon (MSC) from rain-fed systems. Six studies compared SOC changes with time in irrigated systems in which wheat straw was removed or retained. These studies indicated that SOC did not decline when residues were removed. Apparently belowground biomass is supplying C to irrigated soils at a rate sufficient to maintain SOC with time. However, under rain-fed systems, returning residue to the soil was required to maintain SOC. Estimates of MSC were obtained from nine rain-fed wheat system studies. Averaged across all rain-fed MSC values, 4.14 Mg more straw ha(-1) was required to maintain SOC in rain-fed than in irrigated systems. Presently, the rain-fed based MSC values are the best information available to evaluating residue removal effects but caution should be used in applying these in irrigated systems. The results from this limited number of irrigated studies suggest that rain-fed estimates of MSC will overestimate the MSC in irrigated systems and underestimate the available irrigated straw resources. There is need to evaluate the effect of residue removal on SOC for diverse irrigated systems.

AB Harvesting feedstock for biofuel production must not degrade soil, water, or air resources. Our objective is to provide an overview of field research being conducted to quantify effects of harvesting corn (Zea mays L.) stover as a bioenergy feedstock. Coordinated field studies are being conducted near Ames, IA; St. Paul and Morris, MN; Mead, NE; University Park, PA; Florence, SC; and Brookings, SD., as part of the USDA-ARS Renewable Energy Assessment Project (REAP). A baseline soil quality assessment was made using the Soil Management Assessment Framework (SMAF). Corn grain and residue yield for two different stover harvest rates (similar to 50% and similar to 90%) are being measured. Available soil data remains quite limited but sufficient for an initial SMAF analysis that confirms total organic carbon (TOC) is a soil quality indicator that needs to be closely monitored closely to quantify crop residue removal effects. Overall, grain yields averaged 9.7 and 11.7 Mg ha(-1) (155 and 186 bu acre(-1)) in 2008 and 2009, values that are consistent with national averages for both years. The average amount of stover collected for the 50% treatment was 2.6 and 4.2 Mg ha(-1) for 2008 and 2009, while the 90% treatment resulted in an average removal of 5.4 and 7.4 Mg ha(-1), respectively. Based on a recent literature review, both stover harvest scenarios could result in a gradual decline in TOC. However, the literature value has a large standard error, so continuation of this long-term multi-location study for several years is warranted.

ID SUPPLY-SYSTEM TRACEABILITY; ROBOT
AB In-field apple presorting is intended to separate culls that are only suitable for processing or making into juice from apples that would meet the fresh market requirements, so that growers can achieve cost savings in postharvest storage, grading, and sorting. This article reports on the cost benefits analysis of in-field presorting for the U. S. apple industry. Packinghouse costs for culls that would be saved from in-field presorting and in-field presorting yearly costs were defined and estimated to evaluate potential cost benefits for fresh apple growers, processing apple growers, and packinghouses. For fresh apple growers producing 1,400 bins (508 metric tons) or more, in-field presorting is beneficial if the machinery cost is equal to or less than $30,000 (assuming 7-year machine life, 0.3 full-time labor, and 44 bins/day sorting capacity). Smaller fresh apple growers producing 900 bins (327 metric tons) may also benefit from in-field presorting if the cullage rate is more than 40%. In-field presorting is more beneficial to processing apple growers even when the production capacity is as low as 700 bins (254 metric tons). Presorted apples are more consistent in quality, thus enabling packinghouses to better manage postharvest storage/packing operations to meet the market needs. In addition, a properly designed in-field presorting system can provide information about the origin and quality/condition of fruit in each bin, thus enhancing product traceability. The economic analysis results presented in this article are useful in guiding the development of in-field presorting systems that will ultimately benefit the apple industry.

AB Limited experimental data are available to allow direct evaluation of the effects of grazing initiation timing on net returns to dual-purpose wheat systems. The objectives were to simulate the effect of grazing initiation dates on net returns to a wheat (Triticum aestivum L.) - cattle (Bos taurus) enterprise, and to determine economically optimal dates of grazing initiation for selected grazing scenarios. A wheat grazing model was used to simulate the dual systems in north-central Oklahoma for six to eight grazing initiation dates (ranging from 10 October to 30 January), six stocking rates (SR 0.5 to 3 head ha(-1)), four planting dates (1 September to 1 October), three climate scenarios (dry, average, and wet), and an initial wet soil with 75% plant available water. Net returns were further estimated using an enterprise budget approach for the 1999 (favorable to beef production) and 2005 (neutral) markets. For the wheat-cattle production scheme studied in this work, grazing should be initiated as soon as wheat plants are anchored or top dry biomass reaches approximately 1120 kg ha(-1), irrespective of planting dates and climate. As a rule of thumb, for initial wet soils, regardless of climate, the most profitable practices in the region are early September planting, early grazing initiation (before mid-November), and heavy stocking (1.5 to 3 head ha(-1)), while lower SR such as 0.5 are preferable for later grazing initiation. Uncertainty in net return pertaining grazing initiation timing decreases as SR decreases, indicating that high SR appeal to risk lovers and low SR to risk averters.

AB The operational characteristics of center pivot sprinklers are well documented but few studies have been conducted to evaluate the effects that operating characteristics of a particular sprinkler have on infiltration, runoff and erosion for specific soil types. The objective of this study was to evaluate potential runoff and erosion from four commercial center pivot sprinklers on four widely distributed, south central Idaho soils. A modified commercial irrigation boom system was used to simulate center pivot irrigation on experimental runoff plots. Sprinklers used in the study were: 1) Nelson R3000 with brown plate, 2) Nelson R3000 with red plate, 3) Nelson S3000 with purple plate, and 4) Senninger I-Wob with standard 9-groove black plate. Significant differences in runoff and erosion between sprinkler types were observed but were not consistent across all runoff tests or soil types. However, on occasions sprinkler types that visually appear to more evenly distribute sprinkler droplets over the wetted area with respect to time produced the greatest soil erosion for bare soil conditions. This functional difference in spatial distribution of water application with respect to time may have caused sediment to remain in suspension in overland flow for a longer duration allowing sediment to be more readily transported down slope and removed from runoff plots. A 50% reduction in sprinkler flow rate reduced runoff and soil erosion 60% to 80% for the same volume of water applied in six irrigations. The practice of reducing sprinkler flow rate early in the growing season prior to crop canopy development could be an effective management tool for reducing center pivot sprinkler irrigation runoff and erosion.

AB Organic residues on equipment surfaces in poultry processing plants can generate cross contamination and increase the risk of unsafe food for consumers. This research was aimed to investigate the potential of LED-induced fluorescence imaging technique for rapid inspection of organic residues on poultry processing equipment surfaces. High-power blue LEDs with a spectral output at 400 nm were used as the excitation source for a line-scanning hyperspectral imaging system. Common chicken residue samples including fat, blood, and feces from ceca, colon, duodenum, and small intestine were prepared on stainless steel sheets. Fluorescence emission images were acquired from 120 samples (20 for each type of residue) in the wavelength range of 500 to 700 nm. LED-induced fluorescence characteristics of the tested samples were determined. PCA (principal component analysis) was performed to analyze fluorescence spectral data. Two SIMCA (soft independent modeling of class analogy) models were developed to differentiate organic residues and stainless steel samples. Classification accuracies using 2-class ('stainless steel' and 'organic residue') and 4-class ('stainless steel,' 'fat,' and 'feces') SIMCA models were 100% and 97.5%, respectively. An optimal single-band and a band-pair that are promising for rapid residue detection were identified by correlation analysis. The single-hand approach using the selected wavelength of 666 nm could generate false negative errors for chicken blood inspection. Two-band ratio images using 503 and 666 nm (F503/F666) have great potential for detecting various chicken residues on stainless steel surfaces. This wavelength pair can be adopted for developing a LED-based hand-held fluorescence imaging device for inspecting poultry processing equipment surfaces.
