Rachael DerbyshireI am examining how changes in primary prey density influence the foraging and movement behaviour of Canada lynx (Lynx canadensis) in the Kluane region of the Yukon. This study is part of a multi-year collaborative project which aims to understand how prey, conspecifics, and habitat heterogeneity influence population dynamics in a northern predator. A mechanistic understanding of what factors influence lynx movement and foraging behaviour will help inform the drivers of current patterns of population dynamics, and allow for accurate predictions of population stability in the face of current and future environmental change.
