Telmatobius is the most diverse group of anurans in the Andean Altiplano (highlands) Morphologically, these amphibians have a generally conserved morphology but in turn present large intraspecific variation, which has led to a complex taxonomy and systematics. T. marmoratus has the widest distribution of the genus and forms a complex composed of at...
The species that inhabit systems highly affected by anthropic activities usually exhibit this external influence in their gene pool. In this study, we investigated the genetic patterns of populations of Heleobia atacamensis, a freshwater microgastropod endemic to the Atacama Saltpan, a system historically exposed to environmental changes, and curre...
We report the first record of predation on a Helmeted water toad Calyptocephalella gayi tadpole by an adult specimen of the invasive African clawed frog Xenopus laevis in the locality of Pichi, Alhué (Santiago Metropolitan Region). This finding is discussed in the light of new sightings, in which both species have been detected to coexist in differ...
The minute freshwater gastropod Heleobia atacamensis is only known from its type locality Tilopozo, located at the southern end of the Atacama Saltpan, Antofagasta Region, Chile. It is classified as Critically Endangered by the national agency, Ministerio del Medio Ambiente de Chile, due to its restricted distribution. For the first time, we have i...
On the basis of molecular and morphological evidence, we evaluated the taxonomic identity of two species of Andean frogs of the genus Telmatobius: Telmatobius pefauri and T. zapahuirensis, present in the western Andean slopes at the northern extreme of Chile. We also investigated the taxonomic assignment of five populations of Telmatobius recently...
The Andean Altiplano has served as a complex setting throughout its history, driving dynamic processes of diversification in several taxa. We investigated phylogeographic processes in the Telmatobius marmoratus species complex occurring in this region by studying the geographic patterns of genetic variability, genealogies, and historical migration,...
The amphibian genus Telmatobius is a diverse group of species that inhabits the Andes. This study analysed the phylogenetic relationships of 19 species described from the central Andes of Chile and Bolivia, and 12 undescribed populations of Chile. A molecular phylogeny based on mitochondrial DNA 16S and cytochrome b shows that the Chilean species b...

The use of nondestructive methods for obtaining DNA from amphibians (e.g. buccal swabs) allows genetic studies to be performed without affecting the survival of the studied individuals. In this study, we compared two methods of nondestructive DNA sampling, buccal swabs and interdigital membrane or toe-clipping, in several amphibian species of diffe...

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.
