State of knowledge of the Chilean giant frog (Calyptocephalella gayi)

ABSTRACT Globally, at least 43% of amphibian species are declining, due primarily to habitat destruction and modification, over-exploitation, emerging diseases, and invasive alien species. In Chile there are 60 species of amphibians and of these, 62% are endemic and 73% are in a conservation categor...
