David McCorquodale joined the faculty at Cape Breton University in 1990 after completing his graduate work at University of Alberta and Australian National University and then postgraduate training at the University of Calgary.  Initially his interests focused on the evolution of social behaviour in wasps and bees.  To take advantage of research opportunities on Cape Breton Island his focus is now on the beetle fauna of Cape Breton and changes in bird populations on the island.  Besides his research and teaching – which focuses on environmental biology, entomology, natural history and evolution – he serves on the Forestry Advisory Committee for NewPage, Port Hawkesbury, Scientific Committee of the Biological Survey of Canada (Terrestrial Arthropods), the Nova Scotia Species at Risk Working Group, actively participates in the Maritimes Breeding Bird Atlas, assesses the impact of wind energy projects on bird populations and contributes to the monthly Bird Hour on CBC Cape Breton radio. 

Research Interests

Faunistics of insects, especially beetles (Coleoptera) of eastern Canada
Changes in bird populations of Cape Breton Island
The influence of pasture management on insect diversity
The influence of forest management on insect diversity
