Elk migration influences the risk of disease spillover in the Greater Yellowstone Ecosystem
Wildlife migrations provide important ecosystem services, but they are declining. Within the Greater Yellowstone Ecosystem (GYE) some elk (Cervus canadensis) herds are losing migratory tendencies, which may increase spatiotemporal overlap between elk and livestock (domestic bison [Bison bison] and cattle [Bos taurus]), potentially exacerbating pathogen transmission risk.We combined disease, moveme

Estimating the risk of elk-to-livestock brucellosis transmission in Montana
Wildlife reservoirs of infectious disease are a major source of human-wildlife conflict because of the risk of potential spillover associated with commingling of wildlife and livestock. In Montana, the presence of brucellosis (Brucella abortus) in free-ranging elk (Cervus canadensis) populations is of significant management concern because of the risk of disease transmission from elk to livestock.

Spatiotemporal heterogeneity in prey abundance and vulnerability shapes the foraging tactics of an omnivore
Prey abundance and prey vulnerability vary across space and time, but we know little about how they mediate predator–prey interactions and predator foraging tactics. To evaluate the interplay between prey abundance, prey vulnerability and predator space use, we examined patterns of black bear (Ursus americanus) predation of caribou (Rangifer tarandus) neonates in Newfoundland, Canada using data fr
