Trophic interactions are a fundamental topic in ecology, but we know little about how competition between apex predators affects predation, the mechanism driving top-down forcing in ecosystems. We used long-term datasets from Scandinavia (Europe) and Yellowstone National Park (North America) … read more

Predator-induced stress has been used to exemplify the concept of stress for close to 100 years. Walter B. Cannon, one of the pioneers of the study of stress, used predatorinduced stress in wildlife in 1915 to exemplify the ‘fight or … read more

Coyotes, dingoes and wolves are all dogs, as intelligent and loyal as our familiars. Our treatment of them is unconscionable. As a rule, apex predators are the bosses of nature’s regulatory system, promoting ecological richness and stability by suppressing irruptions … read more

We developed models and provide computer code to make carcass recovery data more useful to wildlife managers. With these tools, wildlife managers can understand the spatial, temporal (e.g., across time periods, seasons), and demographic patterns in mortality causes from carcass … read more

Infection risk is assumed to increase with social group size, and thus be a cost of group living. We assess infection risk and costs with respect to group size using data from an epidemic of sarcoptic mange (Sarcoptes scabiei) among … read more

Understanding the regional vocal patterns of various canid species sheds light on animal communication and could help ranchers broadcast “keep away” messages to protect livestock.
