The Headwater Catfish (Ictalurus lupus) is a catfish with olive-colored sides with a few black spots and a silvery abdomen. It occupies clear, temperate waters with a moderate gradient in southwestern New Mexico. It is probably ominvorious and feeds on stream bottoms. The Headwater Catfish 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 Headwater Catfish’s climate change vulnerability is impacted by factors related to distribution and evolutionary potential, which influence its ability to shift in space 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.
