Factors related to the distribution and prevalence of the fungal pathogen Batrachochytrium dendrobatidis in Rana cascadae and other amphibians in the Klamath Mountains

► We surveyed lakes in the Klamath Mountains for amphibians and a fungal pathogen. ► Batrachochytrium dendrobatidis (Bd) is widespread and infects several amphibians. ► Bd infection rate varied with species, life stage, date, and elevation. ► There was no sign of recent, large-scale die-offs in an at-risk frog species.
