Opossums, Shrews and Moles of British Columbia

SERIES: RBCM Handbooks
UBC Press

British Columbia has the greatest diversity of insectivores (shrews and moles) of any Canadian province: twelve species. In some habitats, insectivores are the dominant mammals. British Columbia's only marsupial, the North American opossum, was brought here by humans from eastern North America. But humans rarely see any of these mammals, except for the occasional shrew brought in by the family cats or molehills observed in gardens or on golf courses. Even naturalists are largely unfamiliar with them.

In Opossums, Shrews, and Moles of British Columbia, David W. Nagorsen presents a comprehensive summary of the most up-to-date information on these intriguing mammals. He provides general information on their biology, including ecology, diets, anatomy, relations with humans, and conservation. Illustrated keys aid in identification. In detailed species accounts, the author gives descriptions of each species, along with their identifying characteristics, natural history and taxonomy. Each account is accompanied by illustrations and a provincial range map.

David W. Nagorsen is Curator of Mammals at the Royal British Columbia Museum in Victoria, B.C., and the author, with R. Mark Brigham, of Bats of British Columbia.
