Telmatobius have been disappearing all over the Andes. Of 59 recognized species of Telmatobius, 68%, or 40 species, have populations that are in decline, and the majority of the remaining 11 species are data-deficient (IUCN). T. marmoratus has the broadest distribution of any species within the genus, and is actually a complex of more than one species. T. marmoratus are found in the Andean highland region of southern Peru, northern and central Bolivia and northern Chile, and have the largest elevational distribution (3,000-5,244 m) of the genus. They are also listed as “Vulnerable to Extinction” by the International Union for the Conservation of Nature (IUCN), and like many species in this genus, the population is projected to decrease by more than 30% over the next 10 years due to the factors including chytridiomycosis, over-harvesting for the food trade, and a deterioration in habitat quality as a result of water pollution (http://www.iucnredlist.org/details/57349/0; Ergueta and Morales, 1996, Merino et al. 2005, Von May et al 2008, Seimon et. al 2007, Angulo et al 2008, Catenazzi et al 2010, Catenazzi et al. 2010b, Barrionuevo and Mangione. 2006). This project is designed to provide direct observations on how amphibians, including T. marmoratus, are being affected by two global threats: climate change and disease (chytridiomycosis) in high Andean watersheds of the Cordillera Vilcanota.
