The decline of the harlequin toad, Atelopus varius (Critically Endangered), in Costa Rica and Panama has been dramatic. It has disappeared from suitable habitats, and the cause of its decline might be the fungal disease, chytridiomycosis, the incidence of which might be related to extreme climatic events, in particular drought.
