The Speckled Chub (Macrhybopsis aestivalis) is a slender minnow with a greenish-silver back with purple reflections and silvery sides with scattered black spots. It is typically smaller than 6 cm (2 in) in New Mexico. It is a bottom-feeder, eating insect larvae, detritus, and plants. The Speckled Chub will experience a high degree of climate change 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 Speckled Chub’s climate change vulnerability is impacted by factors related to demography, life history, and abiotic niche, which influence its ability to persist in place and respond to climate change impacts.
