CURRENT S&T / RESEARCH - Contribution to meeting Environment Canada's mandate to guarantee the conservation and protection of wild species

  • Interdisciplinary research on impacts such as pollution (climate warming contaminants, pesticide and acid rain) and natural resource development (forestry, agriculture and fisheries) on ecosystem integrity (biodiversity) and the health of wildlife (waterfowl) caused by human activities
  • Assessment of the vulnerability of breeding birds to climate extremes
  • Characterization of the general biodiversity of a major river (the St. Lawrence)
  • Modelling of water-level effects on aquatic and palustrine birds in the Lake Ontario / St. Lawrence River system
  • Development of an expert satellite imaging system permitting the characterization of the richness of bird life in terrestrial and palustrine environments in southern Québec, leading to decision-making tools now used to promote sustainable development in Canada


Co-direction of graduate ornithology students at a number of Québec universities

Examiner for research grant applications

Reviewer of scientific journal articles
