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 …
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.
Across multiple study sites in Colorado, mule deer body fat was not well explained by spatial or temporal effects, suggesting individual characteristics, particularly the successful weaning of fawns in the previous year are the dominant forces driving variation in body fat.
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.
