Introduction
I am a conservation biologist dedicated to the study of the evolution, biogeography and macroecology of small neotropical vertebrates, with emphasis on amphibians and reptiles. I am part of the research unit team of Instituto Nacional de Biodiversidad (INABIO) of Ecuador, where I develop lines of research in integrative taxonomy, monitoring of threatened species and bioecological characterization in areas of importance for conservation.

Gal apagos snakes are among the least studied terrestrial vertebrates of the Archipelago. Here, we provide a phylogenetic analysis and a time calibrated tree for the group, based on a sampling of the major populations known to occur in the Archipelago. Our study revealed the presence of two previously unknown species from Santiago and R abida Islan...

Ecuador is one of the most biodiverse countries in the world, but faces severe pressures and threats to its natural ecosystems. Numerous species have declined and require to be objectively evaluated and quantified, as a step towards the development of conservation strategies. Herein, we present an updated National Red List Assessment for amphibian...

We provide several lines of evidence to delimit a new species of Hyloscirtus and define its phylogenetic position inside the Hyloscirtus bogotensis group. The new species is the sister taxon to Hyloscirtus mashpi and is related to a clade formed by H. alytolylax and a putative new species from the province of El Oro in, southwestern Ecuador. Hylosc...

The Province of Carchi is a strategic area, where the most important remnants of tropical forests of the Ecuadorian Chocó come together. These contact the western foothills of the Andes, between the Mira and San Juan river basins, and ascend to the paramo platforms above 3400 meters in altitude and all the way to 4800 meters. This impressive altitu...
