A New Piñon Mouse (Peromyscus truei) from Durango, Mexico
"A New Piñon Mouse (Peromyscus truei) from Durango, Mexico" by Robert B. Finley, Jr. is a scientific publication written in the early 1950s. This work is focused on the documentation and classification of a newly identified subspecies of piñon mouse found in Durango, Mexico. It presents detailed morphological characteristics that differentiate this subspecies from its relatives in adjoining areas. The book discusses the findings from a collection of specimens collected by J. R. Alcorn, highlighting the darker pigmentation of the newly identified piñon mouse, designated as Peromyscus truei erasmus. The text outlines the physical traits, habitat, and geographic range of this subspecies, emphasizing its evolutionary adaptations to the surrounding rocky environment. Finley meticulously compares this mouse to others in the Peromyscus genus, providing measurements and diagnostic features that confirm its status as a distinct subspecies. Overall, the publication contributes to the understanding of mammalian diversity in Mexico and emphasizes the role of natural selection in shaping species characteristics.
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.
