1. The distribution of genetic diversity across a species distribution range is rarelyhomogeneous, as the genetic structure among populations is related to the degreeof isolation among them, such as isolation by distance, isolation by barrier,and isolation by environment.2. Jenynsia lineata is a small viviparous fish that inhabits a wide range of habitats inSouth America. To decipher the isolation processes that drive population structuringin J. lineata, we analyzed 221 sequences of the mitochondrial cytochrome c oxidaseI gene (COI), from 19 localities. Then, we examined the influence of the threemost common types of isolation in order to explain the genetic variation found inthis species.3. Our results revealed a marked structuration, with...
