Predicted Batrachochytrium dendrobatidis infection sites in Guyana, Suriname, and French Guiana using the species distribution model maxent

A study predicts significant areas in Guyana, Suriname, and French Guiana where the fungal pathogen Batrachochytrium dendrobatidis (Bd), known for causing chytridiomycosis in amphibians, could establish and proliferate. Using a species distribution model (MaxEnt) with environmental variables and presence data, researchers identified that maximum temperature of the warmest month was the strongest predictor of Bd habitat suitability, inversely correlated with its occurrence. While Guyana and French Guiana showed large, localized suitable areas, Suriname's potential infection sites were more scattered, primarily in high-elevation regions. These findings highlight critical zones for proactive monitoring to mitigate future outbreaks and prevent the spread of this devastating amphibian disease.
