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 …
Foraging behavior underpins many ecological processes; however, robust assessments of this behavior for free-ranging animals are rare due to limitations to direct observations. We leveraged acoustic monitoring and GPS tracking to assess the factors …
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).
We provide a test of the efficacy of the Northwest Forest Plan, showing that despite limiting cutting of old growth forest, wildlfire has caused continued losses and declines in old growth associated birds have been amplified.
We examined the spatial patterns of mule deer predation during periods of high and low natural gas development activity finding complex relationships between predation and both natural and anthropogenic features.
Comparing mule deer reproduction (pregnancy, fetal rates and fetal survival) between areas of low and high density natural gas development, we found limited evidence of an effect of development on reproduction. In 1 of 3 years, fetal survival was lower int he more heavily developed area.
Using a novel method to assess habtiat selection across spatiotemporal scales defined by animals movements, we show that mule deer display scale-dependent responses to most habitat features but scale-invariant avoidance of natural gas development.
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.
