Genetic (Genomic) and Morphological Evidence Suggest That the Korean Endemic Fat Minnow ( Rhynchocypris kumgangensis ) and the Deogyu Population Represent Distinct Species
ABSTRACT Geographically disconnected populations of freshwater fishes often show ecological and genetic divergence in response to opposing selection differentials in different habitat environments, sometimes leading to the formation of ecotypes and even speciation. Nevertheless, evidence for the speciation through allopatric processes in freshwater fish systems remains scarce. Kumkang fat minnow ( Rhynchocypris kumgangensis ), a Korean endemic coldwater fish, has recently been suggested to diverge into a separate s …
