EducationPh.D. 1982. University of Guelph, Department of Zoology. M.Sc. 1979. University of Guelph, Department of Zoology. B.Sc.(hons) 1976. University of British Columbia, Department of Zoology ResearchI employ evidence from biochemical and molecular genetic variation in frogs and toads to decipher the relationships of species, the structure of populations, and mechanisms of evolutionary change. My research centres on species ranges and boundaries and thus looks beyond traditional population-level approaches to understanding biodiversity origins and maintenance. By seeking to understand range edge populations more fully, my research program aims towards understanding the biology of extinctions, the persistence of populations, and the conservation of species.Prizes and honoursQCBS studentsVictoria TawaM.Sc.
