The Mottled Sculpin (Cottus bairdii) is a small (up to 15 cm [6 in]) freshwater fish found in the Animas, Navajo, Pine, and San Juan Rivers in New Mexico, frequently in well-oxygenated water like mountain streams. It feeds mostly on insect larvae but is also known to eat small fish and fish eggs. The Mottled Sculpin (will experience a high degree of climate exposure and has a low adaptive capacity. Overall, it has a Climate Change Vulnerability Index ranking of Extremely Vulnerable under both Representative Concentration Pathway (RCP) 4.5 and RCP 8.5 Scenarios. The Mottled Sculpin’s climate change vulnerability is impacted by factors related to demography, life history, evolutionary potential, and abiotic niche, which influence its ability to persist in place and respond to climate change impacts. It is also impacted by barriers, land-use changes, and other anthropogenic and biologic factors that could increase the effects of climate change.
