Theses, Dissertations and Capstones
Blacknose dace (Rhinichthys) are one of the most common cyprinid fishes in eastern North America. They also have been a topic of debate for over 30 years because morphology-based systematics has failed to clearly define their taxa. Taxonomists classify the complex into two species and one subspecies: the eastern form, R. atratulus atratulus; and the western form R. obtusus obtusus, and southern form R. obtusus meleagris. This research uses the mitochondrial cytochrome b gene and genomic RAG 2 gene in a phylogenetic analysis to help clarify species relations according to differences between each current species. Maps have been created to …
