A morphological comparison of muskrats ( Ondatra zibethicus ) from Newfoundland and New Brunswick
Adult muskrats (Ondatra zibethicus) from Newfoundland (N = 44) and New Brunswick (N = 21) were measured and data obtained were analyzed using multivariate techniques. On the basis of skull measurements it was possible to accurately predict (P < 0.01) the site of origin of individual animals....

Summary: | Adult muskrats (Ondatra zibethicus) from Newfoundland (N = 44) and New Brunswick (N = 21) were measured and data obtained were analyzed using multivariate techniques. On the basis of skull measurements it was possible to accurately predict (P < 0.01) the site of origin of individual animals. Size differences were related to the availability of preferred foodstuffs. Ondatra zibethicus obscurus is considered a valid taxon for the Newfoundland muskrat. |
