Abstract

We report two new locations for Chaetodipus fallax (Merriam 1889) in Baja California Sur, Mexico: the first, south of San Ignacio; and the second, in the plains of Magdalena Bay. These are the southernmost records for the presence of this species and broaden the species’ previously known distribution range in ~400 km. We suggest that changes in weather conditions could explain the southward expansion of the distribution of C. fallax in Baja California Peninsula.

Keywords: adaptation; arid zones; desert; pocket mouse; recent range expansion
