Dr. Darcy Visscher

Assistant Professor, Biology P: 780-465-3500 Ext. 8121 F: 780-465-3534
Education
  • PhD Ecology, University of Alberta, 2010
  • M.Sc. Mammalogy, University of Pretoria, South Africa, 2002
  • B.Sc. ENVS Biology, The King's University College, 2000

Research Interests
My interest is the role individual behaviour plays in ecological processes, in particular how animals trade-off foraging reward and predation risk as well as how animals move through the landscape to maximize their fitness.

Projects

  • Predation risk sensitive foraging in birds
  • Optimal search strategies using genetic algorithms and Levy flights
  • Urban wildlife road crossing behaviour
