Replicated hybrid zones of Xiphophorus swordtails along an elevational gradient.

Molecular ecology - 1 Jan 2011

Abstract excerpt

Natural hybrid zones provide opportunities to study a range of evolutionary phenomena from speciation to the genetic basis of fitness-related traits. We show that widespread hybridization has occurred between two neo-tropical stream fishes with partial reproductive isolation. Phylogenetic analyses of mitochondrial sequence data showed that the swordtail fish Xiphophorus birchmanni is monophyletic and that X....
