This dataset contains two types of distribution models: (1) probability of presence, and (2) abundance. The model type, species, and season depicted in a raster are defined in the file name. File names begin with either abun (indicating that it is an abundance model) or prob (indicating a probability of occurrence model). Following model type is species, for which there are 10 provided: ABDU (American Black Duck), AMEW (American Wigeon), BWTE (Blue-winged Teal), CITE (Cinnamon Teal), GADW (Gadwall), AGWT (Green-winged Teal), MALL (Mallard), MODU (Mottled...

This dataset identifies positive or negative test results for qRT-PCR (quantitative reverse transcriptase polymerase chain reaction) for avian influenza virus through identification of the Type A influenza virus matrix gene from aquatic sediment samples. Sediment samples were collected from waterfowl habitat so as to determine if temporal and spatial differences in virus detection by qRT-PCR were evident among test sites.

These data reflect the digitization of the shorelines of 21 sub-estuaries throughout the Chesapeake Bay (USA) as observed from 2010 through 2014. Shoreline segments are classified into one of seven shoreline types: bulkhead, riprap, developed, natural marsh, Phragmites-dominated marsh, sandy beach, and forest. These data were collected as part of a larger effort to understand the impacts of shoreline hardening on waterbird community integrity.

These data detail the virological sampling results, obtained post release, which include a single positive for clade 2.3.4.4 H5N1 virus of the A/goose/Guangdong/1/1996 (Gs/GD) H5N1 lineage of highly pathogenic IAV. These data also include the movements of the infected bird from release until death as well as four conspecifics marked and released concurrent with the HPAI positive bird.

To improve our understanding of the spatial and temporal trends in transmission risk we developed a model that predicts hotspots of novel virus emergence between domestic and wild birds and incorporates H5N1 risk factors. Models were produced at 30 km spatial resolution across two temporal seasons. Files are named using a TransmisisonDirection_Season_DataType format such that Transmission direction can end in a (poultry to waterfowl) or b (waterfowl to poultry), Season can be breeding (br) or wintering...

Using geographic information software and Monte Carlo simulations, we developed geospatial indices of waterfowl abundance at 1 km resolutions for the breeding and wintering seasons for China, the epicenter of H5N1. Two types of spatial layers were developed: cumulative waterfowl abundance (WAB), a measure of predicted abundance by species, and cumulative abundance weighted by H5N1 prevalence (WPR), whereby abundance for each species was adjusted based on species specific prevalence values....
