FIG. 2 in Going with the Flow: Testing the Role of Habitat Isolation among Three Ecologically Divergent Darter Species

FIG. 2. Chart showing habitat characteristics of each darter species and predicted levels of gene flow between populations based on habitat variables. FST represents population differentiation, while AR represents allelic richness. Arrows pointing up indicate an increase, arrows pointing down a decrease, and horizontal arrows indicate moderate/intermediate levels.
