Tropical snake diversity collapses after widespread amphibian loss.

摘要: Biodiversity is declining at unprecedented rates worldwide. Yet cascading effects of biodiversity loss on other taxa are largely unknown because baseline data often unavailable. We document the collapse a Neotropical snake community after invasive fungal pathogen Batrachochytrium dendrobatidis caused chytridiomycosis epizootic leading to catastrophic amphibians, food source for snakes. After mass mortality contained fewer species and was more homogeneous across study site, with several in poorer body condition, despite no systematic changes environment. The demise amphibian demonstrates repercussive unnoticed consequences crisis calls attention invisible declines rare data-deficient species.
