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...

Capturing Long-Term Change Through Repeat Photography - WEB APPLICATION

The National Park Service and US Geological Survey have been repeating historic photographs in southeastern Utah and other areas of the southwest. Repeat photography collections such as this provide a unique long-term perspective on ecosystem dynamics, including shifts in plant communities, soil erosion and deposition, and evolution of stream and wash channels.

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

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,...

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
