Salamanders in Europe are dying from a disease caused by the "salamander devouring fungus", Bsal. This pathogen has both swimming and encysted zoospores that can be transmitted long distances. It has not been found in the salamander biodiversity hotspot of the world, the Appalachian Mountains of North America..yet. Our research aims to understand how humans and animals can spread Bsal across a landscape and model the outcomes on fatally susceptible North American salamanders.
