Athelognathus patagonicus is an endemic frog from a lagoon in a small area surrounding Laguna Blanca National Park, Northwestern Patagonia. In 2000 it was categorized as endangered because it disappeared from the main water body, the Laguna Blanca. The apparent cause was the introduction of a Patagonian fish “Perch” that had never lived on these lagoons.

The aim of this project is to do surveys and monitor the surrounding lagoons to detect the presence of this frog and study their abundance and phenology. The team will also test tadpole susceptibility and the alteration of aquatic vegetation (the frogs' refuge) as possible causes of their extinction.
