Chytrid Fungus in Amphibians in northern NY

Amphibians are under threat of extinction from many directions including climate change, habitat loss and fragmentation, as well as disease. In particular, chytrid fungus (Batrachochytrium dendrobatidis) and ranavirus are major sources of global amphibian decline. Chytrid fungus results in keratinization of the amphibian's skin, thereby impacting their ability to breathe and reducing survival. In the summer 2015, students and I commenced an assay of local wetlands (e.g., ephemeral ponds, wildlife management areas, reservoirs) while performing our tick sampling. We used sterile swabs to acquire samples of epithelial and potential fungal spores from amphibians we encountered (thus far northern leopard frogs, newts, green frogs, and American toads). We extracted DNA using Qiagen spin columns and are working on optimizing the BD and ITS-1 PCRs.

Stay tuned for our preliminary results...
