Our research line is focused towards the integral study of the variation of characters in an interspecific and intraspecific level, simultaneously considering different ecological (at different analytic level) and historical (phylogeny) aspects. Using different species as models, we inquire the processes and mechanisms that would show differences between populations. To infer processes at a proximal scale we use traditional morphometric and geometric tools, of quantitative genetics (common garden experiments), fieldwork and different DNA sequencing technics. To infer historical processes, we use mitochondrial and nuclear genes applying methods such as phylogeographic, phylogenetic and comparative methods. As an emergent research line, we’ve put our interest in conservation genetics, emphasizing on the genetic and evolutionary components of the different linage and their relationship with landscape genetics.
Our research projects in the past 15 years have been directed mainly to studying the evolution of the Altiplano’s species (Andean Plateau) and the systems that maintain them (lakes, lagoons, bofedales and rivers). This research line corresponds to a collaborative effort between scholars of different faculties addressing a problem of national importance related to the information needed for making decisions about the management of hydric resource in the XV, I, II Región of Chile. Since there’s previous precarious and disperse knowledge about the biodiversity in these systems, we have made the attempt, using a multidisciplinary and collaborative approach, to contribute knowledge about this system, through: a) phylogenetic reconstructions on model species (fish of the genus Orestias, snails of the genus Biomphalaria and Heleobia, amphibians of the genus Rhinella and Telmatobius), b) characterization of each system in abiotic (salinity, pH, oxygen concentration, among others) and biotic terms (biodiversity, biogeographic relationships and history). For this we have used different approaches: limnology, ecology, population genetics, phylogenetic studies, genomics and transcriptomics.
En la primera semana de Enero 2017, el Dr. Marco Méndez y Dr. Alvaro Zuñiga realizaron un curso de verano en las Jornadas de Actualización para profesores “Origen y evolución de los seres vivos” JAP 2017
The Evolution meeting in 2017, will be a joint annual conference of the Society for the Study of Evolution, the Society of Systematics Biologist, and the American Society of Naturalists. This joint meeting will take place in Portland, June 23-27. The registration fees will be available in January, 2017, and the online registration in February, 2017. For […]
Last week some members of our lab were in Bolivia dictating a course for the doctoral program of the Universidad Mayor Real y Pontificia de San Francisco Xavier de Chuquisaca. The name of the course is “Introducción al uso de marcadores moleculares II : Actividades Practicas” and it consisted in a theoretic and a practical […]
