Amphibians are a highly threatened vertebrate group, and populations of these animals have declined drastically. An important global threat to amphibians is the pathogenic fungus Batrachochytrium dendrobatidis (Bd), which causes the disease chytridiomycosis. However, not all species develop chytridiomycosis when exposed to Bd. We compared susceptibility to disease in two species of marsupial frogs and found that Gastrotheca nebulanastes is susceptible, whereas its congeneric G. excubitor is resistant.(...)
