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.
Pleistocene Bats from San Josecito Cave, Nuevo Leon, Mexico
"Pleistocene Bats from San Josecito Cave, Nuevo León, México" by J. Knox Jones Jr. is a scientific publication written in the mid-20th century. This work focuses on the study of bat fossils found in the San Josecito Cave, detailing specific species from the Pleistocene era, some of which are newly identified within this publication. In the book, J. Knox Jones Jr. provides an in-depth analysis of bat specimens collected from San Josecito Cave, highlighting the morphological characteristics and classifications of various bat species. The research is significant as it introduces the new species Desmodus stocki and offers comparative data on other bat species from both Pleistocene and modern contexts. The text includes cranial measurements, descriptions of the specimens, and insights into the paleobiology of bats, contributing to the understanding of biodiversity and evolutionary history in the region. The findings presented are critical for paleontologists and researchers interested in the mammalian fauna of the Pleistocene epoch in North America.
Comments on the Taxonomic Status of Apodemus peninsulae, with Description of a New Subspecies from North China
"Comments on the Taxonomic Status of Apodemus peninsulae, with Description of a New Subspecies from North China" by J. Knox Jones, Jr. is a scientific publication written in the mid-20th century. It presents a detailed examination of the taxonomy of the rodent species Apodemus peninsulae, originally described in the early 20th century. The book likely focuses on the taxonomic classification of this species, specifically examining its relationships with other related species and subspecies based on specimens collected primarily from Korea and North China. In the work, Jones discusses the classification of Apodemus peninsulae and provides a new subspecies designation, Apodemus peninsulae sowerbyi, based on extensive comparisons of morphological characteristics and cranial measurements. The study highlights the distinctions of peninsulae from related species like Apodemus flavicollis and Apodemus sylvaticus, describing key differences in physical features such as skull shape, color, and reproductive traits. Through his analysis, Jones seeks to clarify the taxonomic standing of the species and its subspecies within the broader context of mammalian classification in northeastern Asia, underscoring the need for further research in this relatively under-explored area of zoology.
