Geographic Variation in the Harvest Mouse, Reithrodontomys megalotis, On the Central Great Plains And in Adjacent Regions
"Geographic Variation in the Harvest Mouse, Reithrodontomys megalotis, On the Central Great Plains And in Adjacent Regions" by J. Knox Jones, Jr. and B. Mursaloglu is a scientific publication prepared for the University of Kansas, written in the early 1960s. This research paper focuses on the geographic variation of the western harvest mouse in the central Great Plains and surrounding areas, examining its range, habitat preferences, and subspecies classifications based on extensive specimen analysis. The book provides a detailed study of the morphological and color variations of the harvest mouse across different geographic regions. It reports on findings based on an examination of numerous specimens, highlighting the relative uniformity of the species in terms of pelage color and size variations, compared to other cricetid species. The authors identify two subspecies—Reithrodontomys megalotis aztecus and Reithrodontomys megalotis dychei—characterizing their distinct features based on geographic location and morphological measurements. Alongside anatomical data, the paper discusses the taxonomic history and classification of these subspecies, contributing valuable information to the understanding of rodents in this region.

Geographic Variation in Red-backed Mice (Genus Clethrionomys) of the Southern Rocky Mountain Region
"Geographic Variation in Red-backed Mice (Genus Clethrionomys) of the Southern Rocky Mountain Region" by E. Lendell Cockrum and Kenneth L. Fitch is a scientific publication written in the early 1950s. The book serves as a detailed examination of the red-backed mice, specifically focusing on their geographic variation across the southern Rocky Mountain region. Through this work, the authors aim to clarify the taxonomic status of these small mammals and recognize unnamed subspecies in the area. The book presents extensive findings based on the authors’ research into the red-backed mice, comparing physical characteristics such as pelage and cranial measurements across various geographic variants. The study identifies several distinct subspecies within the genus Clethrionomys, utilizing collected specimens from multiple locations in Wyoming, Colorado, New Mexico, and Arizona. Through detailed descriptions and taxonomic analysis, the authors provide insights into the morphological traits that differentiate these subspecies, contributing valuable knowledge to the field of mammalian biology and aiding in understanding the ecological adaptations of these mice within their diverse habitats.
