The effects of different feed additives on bird performance and the gastrointestinal microbiome of Salmonella-challenged broilers

This dataset contain raw sequence data for 16S amplicon microbiome profiling of broilers challenged with Salmonella and fed several different intervention strategies. Files are tar archives containing zipped fastq raw data files for each sample.

Greater Blue Earth River Basin Sediment Budget Shapefiles

These are the extents of landforms used in the construction of suspended sediment budgets for the LeSueur, Blue Earth and Watonwan Rivers. The extents of bluffs, ravines, lakes, and subwatersheds in 2010 are included, as well as riverbanks from 2008 and 1938.

Vaccination Against Lawsonia intracellularis Decreases Shedding of Salmonella enterica serovar Typhimurium in Co-Infected Pigs and Alters the Gut Microbiome

*Salmonella enterica* is a leading cause of foodborne illness worldwide and pork can serve a source of infection. In this study, we investigated if vaccinating pigs against L*awsonia intracellularis*, a common pathogen of swine that has previously been shown to favor *Salmonella enterica* infection, confers protection against *Salmonella enterica serovar Typhimurium*. We investigated the underlying changes in the gut microbiome mediated by single *S. Typhiumurium* infection compared to co-infection with *L. intracellularis* as well as the effect of vaccination on the microbiome.

Leaf-level trade-offs between drought avoidance and desiccation recovery drive elevation stratification in arid oaks: site environmental data, individual tree stem and leaf physiological data, and analyses

We investigated whether oak species in the Chiricahua Mountains were 1) elevationally stratified, 2) whether that stratification was correlated with temperature minima, maxima, and water availability, 3) if physiological tolerances to freezing or drought stress correlated with elevation ranges, and 4) if traits important to local (elevation) distributions were correlated with climatic values of the wider species ranges. Data were collected at field sites from wild, adult trees in the Chiricahua Mountains, Arizona, USA from 2014-2015.

Environmental Association Analyses Identify Candidates for Abiotic Stress Tolerance in Glycine soja, the Wild Progenitor of Cultivated Soybeans

The present study explores an ex situ conservation collection, the USDA germplasm collection, genotyped at 32,416 SNPs, to identify population structure and test for associations with bioclimatic and biophysical variables in Glycine soja, the wild progenitor of Glycine max (soybean). Candidate loci were detected that putatively contribute to adaptation to abiotic stresses.

Restoration of the 1936 Statewide Forest Survey of Minnesota

Over 300 stand and stock tables and summary of volume tables for Minnesota were restored from the first FIA Lake States forest survey conducted between 1930 and 1938. The level of detail of the data varied, but included area of forest cover types and stand size classes, and number of trees and volumes per acre by individual species. The data was presented in an Access database with a series of tables and queries. Definitions and further explanations about the restored historic data can be found in Staff Paper Series No. 241, Department of Forest Resources, University of Minnesota.

Risk prioritization of pork supply movements during an FMD outbreak in the US - Data and Materials

This study recruited experts from production, harvest, retail, and allied pork industries to assess 30 common pork supply movements for their industry criticality. Movements spanned five categories: equipment, live animal production, genetics, harvest, and people. Experts were recruited via email to the American Association of Swine Veterinarians (AASV) mailing list and their assessments were collected via an online survey. The Data.csv file contains the raw survey responses.

Research, Education, and Economics Information System (REEIS)

The Research, Education, and Economics Information System (REEIS) is a source of information on the research, education and extension programs, projects and activities of the U. S. Department of Agriculture (USDA) National Institute of Food and Agriculture (NIFA), the USDA Forest Service, the USDA National Agricultural Statistics Service, the U. S. Patent and Trademark Office, U. S. Census Bureau, and the U. S. National Science Foundation. The system enables users to measure the impact and effectiveness of research, extension and education programs based on data related to agricultural research; forestry research; students, faculty and degrees related to agriculture; USDA partner institution snapshots; Food and nutrition research; 4-H programs; and agricultural snapshots of each state. Internet links to related agencies, institutions, and data bases are also included.

USDA Forest Service Geospatial Technology and Applications Center (GTAC)

The Forest Service's Remote Sensing Applications Center (RSAC) is in Salt Lake City, Utah, co-located with the agency's Geospatial Service and Technology Center. Guided by national steering committees and field sponsors, RSAC provides national assistance to agency field units in applying the most advanced geospatial technology toward improved monitoring and mapping of natural resources. RSAC's principal goal is to develop and implement less costly ways for the Forest Service to obtain needed forest resource information.
