Examining predation risk and antipredator responses of snowshoe hares in Northern Canada’s boreal forest
DownloadFall 2020
Predators limit prey populations not only through direct killing of prey but also through changes in behavior due to predation risk and negative fitness consequences that result. Prey species are known to respond to both predictable (e.g. risky times and places) and unpredictable variation (e.g....

The sublethal effects of high predation risk on both prey behavior and physiology may have long-term consequences for prey population dynamics. We tested the hypothesis that snowshoe hares during the population decline are chronically stressed because of high predation risk whereas those during...

A ubiquitous problem for all foragers is the trade-off between acquiring food energy while simultaneously avoiding the risk of predation. In central montane Alberta I modelled how ungulate forage changes with succession within cutblocks and the implications for forage availability to ungulates...

Reintroduction of wolves (Canis lupus) to Yellowstone National Park in 1995–1996 has been argued to promote a trophic cascade by altering elk (Cervus elaphus) density, habitat-selection patterns, and behavior that, in turn, could lead to changes within the plant communities used by elk. We...
