The identification of closely related species with partially overlapping distributions is fundamental for effective conservation. Here we analyzed 28 sequenced microsatellites, mtDNA sequences, and morphological data, to describe the connec-tivity, genetic relationship, and distribution of Percilia gillissi and Percilia irwini, two endangered speci...
An understanding of how genetic variability is distributed in space is fundamental for the conservation and maintenance of diversity in spatially fragmented and vulnerable populations. While fragmentation can occur from natural barriers it can also be exacerbated by anthropogenic activities such as hydroelectric power plant development. Whatever th...

Development and characterization of 33 microsatellite markers for Percilia irwini, a threatened species endemic to Chile
Genetics data have provided unprecedented insights into evolutionary aspects of colonization by non‐native populations. Yet, our understanding of how artificial (human‐mediated) and natural dispersal pathways of non‐native individuals influence genetic metrics, evolution of genetic structure, and admixture remains elusive. We capitalize on the wide...
Projects
Project (1)
Our research questions are, (i): How severe are connectivity alterations in river basins between the Aconcagua and the Imperial rivers due to fragmentation by dams and interconnection by irrigation canals?; (ii): What are the main dispersal patterns of native fish species?; (iii): How do connectivity changes affect gene flow and genetic diversity of fish species with different dispersal abilities?; (iv): How alpha and beta diversity patterns respond to the within basin fragmentation and among basin connectivity described in (i)?; (v): How to improve the impacted longitudinal connectivity by developing efficient fish passes for Chilean native fish species? The knowledge generated within the project will allow understanding of the effects of anthropogenic
alterations of riverine connectivity on fish populations and communities and inform management actions to rehabilitate native fish populations.
