Spreading fungal scourge
salamanders succumbing
perfect storm draws near.
Many of the world’s amphibians are under threat from a chytrid fungus (Bd), particularly in the tropics where it is driving many amphibian species towards extinction. More recently a sister species (Bs) has been observed in Western-European salamanders. Observations of a salamander population across two years following initial detection of Bs suggest a rapid population collapse with little recovery. Bs also has an increased transmission strategy over Bd and may behave as a “perfect storm” as it spreads through European populations of salamanders. Stegen et al, 2017.
