Hellbenders are North America’s largest salamanders, living in rivers and growing to an incredible length of over two feet. Eastern newts are tiny and terrestrial, but both are susceptible to a fungal pathogen called Bsal. While Bsal has yet to make an appearance in the global hotspot of salamander diversity that is North America, it has wreaked havoc on populations in Europe, so biologists worry its impact could be even worse if it does. Eastern newts' susceptibility to Bsal coupled with their notable mobility mean they could act as “super-spreaders” of Bsal if the fungus ever gets to North America. For hellbenders, which are already listed as endangered and suffer from habitat degradation, a new pathogen is hardly good news.  On this episode we speak with Dr. Becky Hardman from the University of Tennessee-Knoxville, and Dr. Anna Longo of the University of Florida about these fascinating and unique species, and discuss what is being done to prepare for a Bsal invasion that experts say is inevitable.
