Landscapes of fear describe a spatial representation of an animal's perceived risk of
predation and the associated foraging costs, while energy landscapes describe the spatial …

Declining Arctic sea ice is increasing polar bear land use. Polar bears on land are thought to
minimize activity to conserve energy. Here, we measure the daily energy expenditure (DEE) …

Around the world, climate change has impacted many species. In this study, we used
bioclimatic variables and biophysical layers of Central Asia and the Asian Highlands …

Climate-mediated phenological shifts can cause species to lose access to their primary prey
while increasing opportunities for alternative-prey encounters. Species that are able to …

Climate change is expected to increase the frequency and duration of long-distance swims
by polar bears (Ursus maritimus). The energetic costs of such swims are assumed to be …

Ursids are the largest mammals to retain a plantigrade posture. This primitive posture has
been proposed to result in reduced locomotor speed and economy relative to digitigrade …

Simple Summary Human-caused climate change is proceeding rapidly and providing
challenges to wildlife species, especially those adapted to colder temperatures. We …

Dinosaur foraging ecology has been the subject of scientific interest for decades, yet much
of what we understand about it remains hypothetical. We wrote an agent-based model …

During much of the year, polar bears in western Hudson Bay use energy-conserving hunting
tactics, such as still-hunting and stalking, to capture seals from sea-ice platforms. Such …

Relatively little is known about the feeding ecology of grizzly bears (Ursus arctos) in Wapusk
National Park. Other ursids, polar bears (Ursus maritimus), are well known predators of …
