Mammals of Washington, Volume 2 University of Kansas Publications Museum of Natural History
"Mammals of Washington, Volume 2" by Walter Woelber Dalquest is a scientific publication written in the mid-20th century. This work dives into the study of mammals in the state of Washington, exploring their distribution, ecological habitats, and evolutionary background in light of the geographical and climatic factors impacting the region. It serves as a detailed resource for both naturalists and zoologists interested in the unique mammalian faunas that have developed in this ecologically diverse area. The opening of the book lays the groundwork for an in-depth examination of Washington's mammalian species by discussing the geological history and the effects of glaciation on local fauna. It highlights the uniqueness of the state's current mammalian inhabitants, many of whom are relatively recent immigrants following the retreat of glaciers. The author introduces the concept of life zones and physiographic provinces within Washington, underscoring how these parameters influence the distribution and classification of mammal species. This foundational information sets the stage for subsequent chapters detailing specific species and their habitats across various ecological zones.
Tadarida femorosacca (Merriam) in Tamaulipas, Mexico
"Tadarida femorosacca (Merriam) in Tamaulipas, Mexico" by Walter W. Dalquest and E. Raymond Hall is a scientific publication written in the mid-20th century. This work contributes to the field of mammalogy, specifically focusing on the distribution and identification of the pocketed free-tailed bat species, Tadarida femorosacca, in the region of Tamaulipas, Mexico. The content of the publication includes a detailed account of the discovery of two specimens of Tadarida femorosacca, one alive and one deceased, found in a cave in Tamaulipas. The authors report that this finding extends the known geographic range of the species significantly from its previously documented location in Jalisco, Mexico. Included in the discussion are morphological measurements of the skulls of the specimens, references to prior research, and an observation of a large population of bats likely residing in the cave, evidenced by substantial guano deposits. The publication serves as an important record for researchers interested in the biodiversity and distribution of bat species in Mexico.
A New Bat (Genus Myotis) From Mexico
"A New Bat (Genus Myotis) From Mexico" by Walter W. Dalquest and E. Raymond Hall is a scientific publication written in the mid-20th century. This document focuses on the details surrounding the discovery and classification of a new bat species, "Myotis argentatus", found in Mexico. The book outlines the circumstances of the discovery, which took place near the Rio Coatzacoalcos when Dalquest managed to collect two bat specimens from a decayed tree trunk. It details the distinctive physical characteristics of the newly identified species compared to other bats within the genus "Myotis", particularly noting variations in skull structure, body size, and fur coloration. The text provides a thorough comparison with another known species, "Myotis albescens", discussing specific measurements and morphology that set them apart. Overall, this work contributes to the understanding of bat diversity in Mexico and offers foundational taxonomic information for future research in chiropterology.
