Identification and Recent Distribution of White-Footed Mice (Peromyscus) in New England

Abstract

External features and quantitative cranial characteristics can be used to distinguish between Peromyscus leucopus and P. maniculatus where they occur sympatrically in New England. Discriminant function analysis was used to prepare a test by which skulls of adults of these species can be identified. Geographic and ecological distributions of white-footed mice in New England were reviewed.
