Mammals of Chihuahua: taxonomy and distribution
Authors/Creators
Abstract (English)
STUDY OF PUBLISHED RECORDS and about 6500 specimens of native mammals of the state of Chihuahua, Mexico, revealed 122 species; at least 17 other species probably occur in the state. The number of species in any one area, however, is only about 35 to 55. Illustrated keys are based on external and cranial characters and also include 10 domestic and introduced species. The taxonomic status within Chihuahua of each species and subspecies is considered, including intrasubspecific variation when observed. A synonymy of names used for Chihuahuan specimens of each taxon is given. Specimens examined are listed and localities are mapped. Analysis indicates three major faunas in the tropical coastal plain, the wooded sierra, and the grassy to desert plateau. These faunas are correlated with geography, topography, climate, and vegetation.
