Squeezed by a habitat split: Warm ocean conditions and old-forest loss interact to reduce long-term occupancy of a threatened seabird

Theory predicts that species requiring multiple habitat types simultaneously should have heightened sensitivity to anthropogenic pressures, yet tests of this prediction are especially rare. We tested whether breeding site occupancy of the threatened …

Synergistic effects of climate and land‐use change influence broad‐scale avian population declines

Bird species in the Pacific Northwest of the United States declined most in areas that had both habitat loss and climate change (measured as temperature and precipitation).

Black bear population ecology in Ontario

This project is focused on understanding what factors influence variation in black bear population density across the province of Ontario. We are using non-invasive sampling and spatial capture-recapture models to estimate black bear population density and relate variation in density to factors such as harvest, habitat fragmentation and climate.

Mule deer and natural gas development in the Piceance Basin

The focus of this research is to understnad how natural gas development influences the behavior and population dynamics of mule deer. Natural gas development increased rapidly throughout western North America through the 2000s.
