Fungi have not traditionally been regarded as a conservation threat. Yet, many newly discovered fungal diseases are threatening wild and domestic animals, agriculturally important crops, and human health. Fungal diseases have caused some mass-mortality events and potentially extinctions in vertebrate hosts. The most notable examples include white-nose syndrome in bats and amphibian chytridiomycosis.
Our working group is considering the theoretical mechanisms that could predispose host populations to extinction. We are asking if these mechanisms are sufficient to explain the large impacts that recently emerging fungal diseases, such as chytridiomycosis and white nose syndrome, are having on their host populations, or if other unique features of fungal diseases are contributing to their impacts. We are using pre-existing datasets to address specific questions regarding transmission, rate of spread, the range of host species and pathogen persistence independent of the host, all of which are factors implicated in disease-induced extinction. We are also addressing the conservation challenges associated with highly lethal emerging diseases in wildlife and making specific recommendations for research and conservation for newly emerging fungal diseases that threaten their hosts with extinction.

Working Group 1: We had eighteen participants from four countries attended our first meeting on March 18-22, 2013. Our group was diverse, including participants from different career stages (e.g. graduate students and full professors) and from different scientific fields (e.g. molecular ecologists, physiologists, mathematical modelers, epidemiologists and evolutionary biologists).

Working Group 2: Seventeen participants joined our second meeting on September 12-14, 2013, including four people by videoconference. We continued with our work on a second manuscript entitled "Context dependent conservation responses to wildlife disease". We aim to submit this second paper to a conservation journal. We also outlined additional future manuscripts and assigned sub-groups to work on them.
