First Record ofChrosomus erythrogaster(Cypriniformes: Cyprinidae) in the Mobile Basin

Abstract

We document the discovery of Chrosomus erythrogaster (Southern Redbelly Dace) in the Bankhead National Forest, Double Springs, AL. This collection represents the first documented collection of C. erythrogaster in the Mobile Basin and adds to the biodiversity found in the Bankhead National Forest. Biogeographically, the discovery of C. erythrogaster at this locality leads us to propose the idea of interbasin transfer through subterranean pathways. No evidence exists for stream capture through surface waters, and bait-bucket transfer is unlikely given the isolation of the area due to its wilderness designation.
