Research themes

  • Effects of lemming fluctuations on predator/prey interactions between geese, raptors and foxes on Bylot Island, Nunavut.
  • Feeding ecology of herbivores in relation to the response of plants to grazing.
  • Growth bioenergetics in young precocial birds in relation to food quality and energy expenditure.
  • Reproductive strategies, demography, migration, energy balance, autoecology and trophic relations in the Greater Snow Goose.
  • Study of survival and movements (dispersal, migration) with capture/recapture models.
  • The role of trophic interactions and abiotic factors in regulating avian populations: the case of the Greater Snow Goose.
  • The role played by food availability and its seasonal variations in several aspects of reproduction in birds, including body condition of individuals, egg laying date, clutch size and fledging success.
