Ray T. Alisauskas

Research Scientist - Arctic ecosystems and waterfowl conservation and management

CURRENT S&T / RESEARCH - Contributing to Environment Canada’s mandate to ensure wildlife is conserved and protected

  • Arctic ecosystem research with emphasis on arctic-nesting geese as keystone species that influence arctic vegetation and other wildlife
  • Wildlife population biology with emphasis on population dynamics and nutritional ecology of arctic-nesting and prairie-nesting geese and seaducks
  • Estimation of wildlife population size using aerial survey, hunter survey, and mark-recapture methods
  • Estimation of recruitment and survival in waterfowl populations and the role of exploitation through hunting
  • Focus of long-term research on population biology of waterfowl is at Migratory Bird Sanctuaries: Queen Maud Gulf (since 1990) in Nunavut and Redberry Lake (since 2000) in Saskatchewan

PROFESSIONAL ACTIVITIES / INTERESTS

Scientific and organizing committee membership for (1) North American Duck Symposium and (2) North American Arctic Goose Conference and Workshop

Member, Arctic Goose Habitat Working Group under the North American Waterfowl Management Plan

Member and North American Liaison, Goose Specialist Group of Wetlands International/World Conservation Union
