We investigated the dynamics of canine distemper virus (CDV) in grizzly bears (Ursus arctos) and wolves (Canis lupus) of the Greater Yellowstone Ecosystem (GYE) using serological data collected from 1984 to 2014. 565 sera samples were obtained from 425 unique grizzly bears (134 females and 291 males) from 1984 to 2014 and 319 sera samples were obtained from 285 unique wolves (130 females and 155 males) from 1996 to 2014. Here we provide the unique identifier for each individual, the species and sex, the date the individual was captured, the estimated birth year and age, and the CDV antibody titer results based upon serum neutralization assays.

Remotely sensed elk locations were derived from satellite and Unmanned Aerial Systems (UAS) imagery collected during the winter of 2018 and the winter and spring of 2019 at the National Elk Refuge in Jackson, Wyoming and compared to locations from Global Positioning System (GPS) collars from 2017 - 2019. This data release provides the source, date, time, latitude, and longitude of elk locations and the type of analyses the location data were used for in the accompanying manuscript by Graves and others 2021. DOI will be provided once supplied by the journal.

A total of 200 soil samples were collected in the Greater Yellowstone Ecosystem in Grand Teton National Park and the National Elk Refuge in July 2019 for chronic wasting disease (CWD) monitoring purposes. To collect samples from locations where ungulates are most likely to be shedding or encountering CWD, we targeted elk collar data locations, known migration routes of mule deer and elk, and areas where yearly elk supplemental feeding generally occurs on the National Elk Refuge. We sampled 10 transects in Grand Teton National Park and 10 transects in the National Elk Refuge, each 1,000 meters in length. We collected soil samples every 100 meters along the transect for a total of 10 samples per transect. Terra Core...

Wildlife aggregation patterns can influence disease transmission. However, limited research evaluates the influence of anthropogenic and natural factors on aggregation. Many managers would like to reduce wildlife contact rates, driven by aggregation, to limit disease transmission. We develop a novel analytical framework to quantify how management activities such as supplemental feeding and hunting versus weather drive contact rates while accounting for correlated contacts. We apply the framework to the National Elk Refuge (NER), Wyoming, USA, where the probable arrival of chronic wasting disease (CWD) has magnified concerns. We used a daily proximity index to measure contact rates among 68 global positioning system...
