Plague causes fragmentation of prairie dog colonies in Conata Basin, South Dakota from 1993 – 2015

This data was used to investigate the invasion of a non-native disease, plague, to a keystone species, prairie dogs, in Conata Basin, South Dakota, United States. We documented the resulting extent of fragmentation and habitat loss in western grasslands using colony boundaries mapped by the USFS every one to three years from 1993 - 2015. Specifically, we assessed how the arrival of

Non-listed disease report to OIE (World Organisation for Animal Health) for the 1st semester of 2019

As a member of the World Organisation for Animal Health (OIE), and the reporting authority for the United States, the USGS National Wildlife Health Center (NWHC) is responsible for reporting wildlife disease outbreaks that involve diseases which are not OIE-listed (https://www.oie.int/wahis_2/public/wahidwild.php# ). These...

Boreal toad survival data in relation to Bd status and community composition

These data represent capture mark recapture data from toads, and results of testing for Bd (Batrachochytrium dendrobatidis) the pathogen that causes amphibian chytridiomycosis on individuals. The data span from 2004-2016 at three sites in Montana where boreal toads were declining. The data also include temperature measurements at the sites and information on the egg counts and Bd prevalen...

Data on serology results for green turtles with and without fibropapillomatosis from Hawaii and Florida

Fibropapillomatosis (FP) is a tumor disease associated with a herpesvirus (Chelonid herpesvirus 5-ChHV5) that affects mainly green turtles globally. Understanding the epidemiology of FP has been hampered by lack of robust serological assays to monitor exposure to ChHV5. This is due in part to inability to efficiently culture the virus in vitro for neutralization assays. Here, we expr

E2NHDPlusV2_us: Database of Ancillary Hydrologic Attributes and Modified Routing for NHDPlus Version 2.1 Flowlines

The National Hydrography Dataset Plus, Version 2 (NHDPlusV2) is an attribute rich, digital hydrologic network for the Conterminous U.S. developed by the U.S. Environmental Protection Agency (EPA) and U.S. Geological Survey (USGS). SPAtially Referenced Regressions On Watershed attributes (SPARROW), is a process-based/statistical model that relies on a digital hydrologic ne

Pseudogymnoascus destructans survival at elevated temperatures – Artificial media count data

The survival of Pseudogymnoascus destructans (Pd) was evaluated at temperatures outside of its thermal range of growth on three different artificial growth media; Sabouraud dextrose agar (SD), brain-heart infusion agar (BHI), and brain-heart infusion agar supplemented with 10% sheep red blood cells (BHI+B). Pd was harvested from starting cultures grown of MEA agar at 7%C

Avian Influenza Virus Test Results from Active Surveillance of North American Wild Birds Collected by Department of Interior from 2006-2011

Influenza A viruses are one of the most significant viral groups globally with substantial impacts on human, domestic animal and wildlife health. Wild birds are the natural reservoirs for these viruses, and active surveillance within wild bird populations provides critical information about viral evolution forming the basis of risk assessments and counter measure development. Unfortunately,...

Histopathology of zebra finches (Taeniopygia guttata) orally exposed to clothianidin (ver. 2.0, October 2019)

This dataset reports select histopathological changes in liver, kidney, gonad, spleen, brain, heart, skeletal muscle, lung, or adrenal gland of zebra finches exposed to 15mg/kg, 18mg/kg, 30mg/kg, 60mg/kg, 75mg/kg, 125mg/kg, or 250mg/kg clothianidin (CTD) (with controls) by gavage, in water, or on millet seed either as a single dose or for 7 da

Common murres collected in Alaska from January 1, 2015 through December 31, 2016 and shipped to USGS National Wildlife Health Center for cause of death determination

About 62,000 dead or dying common murres (Uria aalge), the trophically dominant fish-eating seabird of the North Pacific, washed ashore between summer 2015 and spring 2016 on beaches from California to Alaska. Most birds were severely emaciated and, so far, no evidence for anything other than starvation was found to explain this mass mortality. Three-quarters of murres were found in

Relating tissue egg counts to eggs/g of spleen in Hawaiian green turtles

The present study proposes a new methodology for the quantification of parasite eggs in animal tissue. Quantification of parasites are important to understand epidemiology of spirorchiid infections in sea turtles, however different methodologies for quantifying Spirorchiidae eggs in turtle tissues have been used. The most representative way to quantify Spirorchiidae burdens in tissues is...
