Low Genetic Diversity in Diplomystes camposensis, an Endemic and Endangered Catfish from South Chile.

ABSTRACT: Carlos P. Muñoz-Ramírez, Evelyn Habit, Peter J. Unmack, Jerald B. Johnson, and Pedro F. Victoriano (2016) Despite the fundamental importance of the family Diplomystidae for understanding catfish evolution, its species are poorly known and most of them endangered. Diplomystes camposensis, restricted to a single river basin in southern Chile, is perhaps the most vulnerable species due to its small geographic range and imminent habitat alterations by dam constructions. Using mitochondrial DNA sequences, we describe the genetic diversity across its entire distribution in the Valdivia basin and test hypotheses related to the impact of glacial cycles on the genetic diversity and structure. We found that Diplomystes camposensis has low genetic diversity and structure across t
