Southern Deer Mouse (Peromyscus labecula) lives in desert grasslands across Southwestern North America. It feeds on seeds and insects. Its conservation status is Least Concern.
Fascinating facts about the Southern Deer Mouse
- The southern deer mouse was recognised as a separate species in a 2019 study that split it from the eastern deermouse. The revision promoted the former subspecies labecula, blandus and fulvus to full species status, a change adopted by the American Society of Mammalogists.
- Scientists once grouped the southern deer mouse with the North American deermouse, now called the eastern deermouse, treating it as conspecific. It was listed under the subspecies names P.
- The mouse's distribution runs from southern New Mexico and western Texas across the Southwestern United States. From there its range continues southward, reaching its southernmost limit in Oaxaca, the Mexican state at the edge of southern Mexico. This north-to-south stretch places the species in both United States and Mexican habitats, spanning diverse climatic zones.
- In the southern part of its range the southern deer mouse lives alongside the black-eared mouse, P. This overlap, described as sympatry, occurs where their habitats meet in the southern portion of the species' distribution. Both rodents are found in the same Mexican locales, sharing the ecological space without separating into distinct zones.
- The southern deer mouse, scientifically named Peromyscus labecula, belongs to the rodent family Cricetidae. It is a member of the genus Peromyscus, a group of New World mice commonly referred to as deermice. Its range extends across both the United States and Mexico, occupying habitats from southern New Mexico and western Texas down to Oaxaca in southern Mexico.
