Necropsy reference number and summary collection information for Washington state population of northern sea otters examined during 1989-2010

Morbillivirus epidemics in marine mammals first gained prominence in 1988 when an outbreak of phocine distemper virus (PDV) occurred in European harbor seals (Phoca vitulina vitulina). Prior to 2001, all serosurveys for morbilliviruses in sea otters (Enhydra lutris) in California, Washington and Alaska documented a 0% seroprevalence. The first published serodetections of morbi

Fleas collected from black-tailed prairie dog burrows in 2016 and 2017

The data are a list of the number and species of fleas that were collected from black-tailed prairie dog burrows in Montana, North Dakota, South Dakota, Colorado, and New Mexico. Fleas were collected by swabbing ~100 burrows at 3 sites at each of 6 sites. Burrows were sampled twice each summer during 2016 and 2017.

Histopathology of bearded dragons (Pogona vitticeps) exposed to Nannizziopsis guarroi

This work is part of a study demonstrating that the fungus Nannizziopsis guarroi is the cause of the disease known as yellow fungus disease in bearded dragons (Pogona vitticeps) by fulfilling Koch’s postulates. In this study, bearded dragons were exposed to N. guarroi to assess gross and microscopic lesion development and the ability to re-culture the fungus from infected sites. At

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

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
