Mammals of the Grand Mesa, Colorado
"Mammals of the Grand Mesa, Colorado" by Sydney Anderson is a scientific publication written in the mid-20th century. This work focuses on the diverse mammalian species found in the unique montane habitat of the Grand Mesa, Colorado, highlighting the ecological significance of this area that stands apart from the surrounding lowlands. The author discusses various mammal species, their habitats, and the ecological observations made during field research. The book provides detailed accounts of 22 species of mammals documented during a field study on the Grand Mesa, along with additional observations of five species. The research gathered by a team from the Museum of Natural History covers the geographical range of certain subspecies, extending known ranges for some mammals westward. The species cataloged include shrews, voles, and various rodents, with discussions on their habitat preferences, reproductive conditions, and ecological roles within the montane ecosystem. Anderson's findings contribute to a better understanding of the wildlife inhabiting this unique high-altitude environment, underscoring the importance of conservation efforts for such specific habitats.
Robert B. Finley
A New Subspecies of Wood Rat (Neotoma mexicana) from Colorado
"A New Subspecies of Wood Rat (Neotoma mexicana) from Colorado" by Robert B. Finley, Jr. is a scientific publication that was released in the early 1950s. This document presents a detailed study concerning the identification and description of a previously unnamed subspecies of wood rat, known scientifically as Neotoma mexicana scopulorum, found in eastern Colorado. The work is aimed at contributing to the field of mammalogy, specifically expanding knowledge about the biodiversity and distinct characteristics of wood rats in that region. In this publication, Finley discusses the morphological differences between Neotoma mexicana scopulorum and other known subspecies, highlighting unique cranial features, size variations, and coloration traits that distinguish this new subspecies from its relatives, such as N. m. fallax and N. m. inopinata. The text includes comprehensive measurements and descriptions, along with habitats and ecological observations based on field and museum studies. Finley provides data collected from various locations in Colorado and New Mexico, presenting a rigorous and methodical approach to documenting this significant discovery in the study of North American rodents.
E. Raymond (Eugene Raymond) Hall
A New Pocket Gopher (Genus Thomomys) From Wyoming and Colorado
"A New Pocket Gopher (Genus Thomomys) From Wyoming and Colorado" by E. Raymond Hall is a scientific publication written in the early 1950s. This book presents a detailed description and classification of a new subspecies of pocket gopher found in the Sierra Madre Mountain Range of Wyoming and Colorado. The focus is on contributing to the field of natural history, specifically the taxonomy of small mammals. In this publication, Hall introduces the new subspecies, named Thomomys talpoides meritus, based on specimens collected from the region. He provides a thorough analysis of the physical characteristics, habitat, and measurements of this gopher compared to other subspecies. The study emphasizes the differences in size, color, and skull structure that distinguish T. t. meritus from its neighboring subspecies, T. t. rostralis and T. t. clusius. Overall, the work contributes valuable knowledge to the field of mammalogy and showcases the importance of detailed field research in understanding biodiversity.
E. Raymond (Eugene Raymond) Hall
A New Pocket Gopher (Genus Thomomys), from Eastern Colorado
"A New Pocket Gopher (Genus Thomomys), from Eastern Colorado" by E. Raymond Hall is a scientific publication written in the early 1950s. This work represents a study focused on the taxonomy of pocket gophers, specifically examining previously misclassified specimens from east-central Colorado and proposing a new subspecies. The text is aimed at scholars and researchers in the field of mammalogy and provides detailed anatomical and geographic information regarding this rodent species. In this publication, Hall identifies and describes a new subspecies of the pocket gopher, named "Thomomys talpoides retrorsus", which was discovered in the region of eastern Colorado. By analyzing specimens and their characteristics, Hall distinguishes this subspecies from others previously categorized and offers a thorough comparison based on various skull measurements, coloration, and other anatomical features. The study not only clarifies the subspecific identity of these gophers but also addresses previous taxonomic confusion, contributing valuable knowledge to the understanding of mammalian diversity in North America.
E. Raymond (Eugene Raymond) Hall
Two New Pocket Gophers from Wyoming and Colorado
"Two New Pocket Gophers from Wyoming and Colorado" by E. Raymond Hall and H. Gordon Montague is a scientific publication written in the early 1950s. This work details the identification of two previously unnamed subspecies of the northern pocket gopher, specifically focusing on their geographic variations and morphological distinctions. The publication serves as a significant contribution to the field of mammalogy, particularly concerning the study of rodent populations in the western United States. The book presents the findings of Montague’s study of the pocket gophers in Wyoming and Hall's subsequent research examining related specimens from Colorado. It provides detailed descriptions of the two new subspecies, namely "Thomomys talpoides rostralis" and "Thomomys talpoides attenuatus", highlighting their distinct characteristics, such as size, color, and skull morphology. The authors also compare these new subspecies to adjacent ones, discussing geographic distribution and variation, which enhances the understanding of the ecological and evolutionary dynamics of pocket gophers in this region.
