About This Book

A regional study documents the distribution and habitat associations of the meadow mouse in Wyoming and Colorado, emphasizing occupation of moist mountain grasslands separated by xeric or rocky barriers. The author analyzes more than 1,100 specimens collected over several field seasons, employing 27 measurements and fifteen key external and cranial characters with statistical comparison of local series. Results highlight irregular population fluctuations and partly isolated local populations that exhibit modest subspecific differentiation likely influenced by selection and genetic drift. Taxonomic conclusions adjust previously assigned ranges, recognize local variants, and describe two additional subspecies.

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.
