Fishes known from the Colorado River basin successfully modeled and accepted under study criteria (see text).

Maximum probability of occurrence in BCW, number of collecting events documenting species occurrences in BCW from surveys and historical collections, average test AUC, variable set used in model construction, and number of records used in training and testing models shown for each species. Bold marks native species with >0.5 max watershed probability, but lacking documentation by collections from the BCW. (*) represents a vouchered record of “Macrhybopsis sp,” here arbitrarily identified as M. marconis, but that could be M. hyostoma. (I) represents species introduced (not native) to the Colorado River basin. (+) Refer to Table 3 for details on variable sets.
