Abstract
The current geographic distribution of Chilean freshwater fishes has likely been shaped by several abiotic factors, including fragmentation caused by the Pacific Ocean, glaciers that covered the entire southern part of Chile during the Pleistocene Epoch, and orogenic and volcanic activity. Exactly how these factors have impacted population histories of Chilean freshwater fishes remains unknown. In this project, we examined the phylogeographic history of the freshwater catfish Trichomycterus areolatus, a species native to Chile that occurs across most of the latitudinal range of this country (Fig. 1). Given the distribution and ubiquity of this species, we anticipate that the results of this work will provide insight into the predominant effects of historical events on the genetic and geographical distribution of Chilean freshwater taxa.
