About This Book

A regional taxonomic study examines geographic variation in the meadow vole across Wyoming, Colorado, and adjacent areas, employing a five-point pelage-color scoring system anchored to two standard skins and detailed skull measurements. Specimens from numerous localities were scored, averaged, and mapped; cranial metrics were measured and compared statistically, with pair-matching used to control for size and age. Analysis documents a geographic pattern of dark and pale populations and other morphological differences, leading to recognition of multiple subspecies within the study area and the proposal of three additional subspecies to better reflect the observed variation.

About the Author

Sydney Anderson

Sydney Anderson was a notable biologist and researcher specializing in mammalogy, particularly in the study of bats and rodents. His work contributed significantly to the understanding of various species within these groups, with a focus on their subspeciation and ecological ranges. Among his key publications are "Extensions of Known Ranges of Mexican Bats" and "Mammals of Mesa Verde National Park, Colorado," which reflect his dedication to documenting and analyzing mammalian diversity in North America. Anderson's research has been influential in the fields of wildlife biology and conservation, providing valuable insights into the habitats and behaviors of lesser-known species.
