The Yellow-nosed Cotton Rat (Sigmodon ochrognathus; 15-20 cm [6-8 in]; 50–80 g [2-3 oz]) is found in the southwestern US and northern Mexico. Aside from the ochre color on its snout, its fur is typically brown or gray, which provides it camouflage from predators. It occupies grasslands, deserts, and rocky slopes. It is herbivorous, eating mostly grasses and seeds. The Yellow-nosed Cotton Rat will experience a high degree of climate exposure and has a moderately high adaptive capacity. Overall, it has a Climate Change Vulnerability Index ranking of Less Vulnerable under the Representative Concentration Pathway (RCP) 4.5 Scenario and Moderately Vulnerable under the RCP 8.5 Scenario. The Yellow-nosed Cotton Rat’s climate change vulnerability is impacted by movement factors, which influence its ability to shift in space.
