About This Book

The paper analyzes geographic and morphological variation in the western harvest mouse across the central Great Plains and adjacent regions using 1,350 museum specimens. It documents range and habitat associations, measures external and cranial characters, and examines pelage development and molt patterns. Secondary sexual variation was tested and found negligible, so sexes were pooled for analysis. The authors compare populations to evaluate the application of several subspecific names and conclude that geographic differentiation is relatively modest compared with other regional cricetids, supporting taxonomic judgments based on measurement-based comparisons of specimens.
