Batrachochytrium dendrobatidis (Bd) is causing catastrophic declines in amphibians worldwide. However, its impact varies widely between species and populations with a potential for coexistence in some host-pathogen systems. We aim to identify areas in Catalonia (NE Spain) where Bd is present but has little impact on amphibian populations. Understanding the mechanisms that underlie this coexistence may be key to mitigate the ongoing loss of biodiversity caused by Bd.
