Subspeciation in Pocket Gophers of Kansas, [KU. Vol. 1 No. 11]

"Subspeciation in Pocket Gophers of Kansas" by Bernardo Villa-R. and E. Raymond Hall is a scientific publication produced by the University of Kansas, likely written in the mid-20th century, specifically around the late 1940s. This work focuses on the taxonomic status and distribution of various subspecies of pocket gophers belonging to the genus "Geomys" found across Kansas, providing detailed morphological descriptions and geographical analysis. The authors conducted a thorough examination of 335 specimens, identifying several subspecies of pocket gophers in Kansas and highlighting intergradation between them. The study reveals that the previously recognized distinctions among different gopher types were too rigid and points to a more fluid classification based on geographical distribution and morphological variants. By analyzing the structural features, the authors arranged the species under the name "Geomys bursarius", in recognition of the oldest available name, and presented a detailed description of the five recognized subspecies, noting their unique characteristics, geographic ranges, and relationships to one another. The research contributes significantly to our understanding of pocket gopher subspeciation, emphasizing the complexity of species classification in natural populations.
