 Abstract, the fungus the tracheocytrium salamandriverans, BSAL, which causes a deadly disease called catridiomicosis in amphibians, has been found in Europe and could potentially spread to North America. In order to assess the potential impacts of this disease, researchers conducted dose-response experiments with 35 North American species from 10 different families, including level stages of five species. They found that 74% of the species were infected by BSAL and 35% died as a result. This suggests that BSAL could cause significant damage to amphibian populations in North America. Researchers also used environmental suitability models and geographical data to predict where the disease would have the greatest impact. They concluded that the Appalachian region and the west coast of the US are likely to experience the highest levels of biodiversity lost due to BSAL. This article was authored by Matthew J.
