Education

Biography
Darcy’s education includes a B.Sc. in Environmental Studies (Biology) from The King’s University in 2000, a MSc in African Mammalogy from the University of Pretoria in South Africa, and a Ph.D in Ecology from the University of Alberta in 2010. His primary research interest is the role that behaviour plays in ecological processes, in particular, how animals trade-off foraging reward and predation risk. He investigates these topics using the three pronged approach of developing theory, building models to test theory, and grounding these results using statistical analysis of field data.

Projects

  • Investigations into the population level consequences of the non-consumptive effects of predation on porcupine.
  • The role of human disturbance in altering the spatial and temporal distribution of ungulates and canids.
  • Factors influencing the zoonotic potential of Echinococcus in peri-urban canids.
  • Predation risk-sensitive foraging in urban birds.
