The Northern Pygymy Mouse (Baiomys taylori ater) is a small (10-12 cm [4-5 in]; 7-10 g [0.2-0.4 oz]) rodent in the vole family (Cricetidae) that is found in the southwestern regions of the US and Mexico. It is omnivorous and eats seeds, grains, and small insects. The Northern Pygmy Mouse is charactarized by its small size and comparitively large ears. Its habitats range from grasslands and deserts to and forested areas with dense ground cover. The Northern Pygmy Mouse will experience a high degree of climate exposure and has a high adaptive capacity. Overall, it has a Climate Change Vulnerability Index ranking of Less Vulnerable under both Representative Concentration Pathway (RCP) 4.5 and RCP 8.5 Scenarios. The Northern Pygmy Mouse’s climate change vulnerability is impacted by factors related to distribution and movement, which influence its ability to shift in space.
