Description
Summary:Crawshaw, L., Buchanan. T., Shirose, L., Palahnuk, A., Cai, H.Y., Bennett, A.M., Jardine, C.M., Davy, C.M. We conducted surveillance for two chytrid fungi (Batrachochytrium dendrobatidis and B. salamandrivorans) in south-central Canada, in an area where previous niche modelling suggests low habitat suitability for B. dendrobatidis. Sampling of 1041 amphibians across Ontario and Akimiski Island (Nunavut) revealed that B. dendrobatidis is ubiquitous in our study area, but did not detect B. salamandrivorans. Niche models informed by these data show high habitat suitability for B. dendrobatidis, and temperature models suggest high habitat suitability for B. salamandrivorans if it is introduced, emphasizing the need for enhanced coordinated, trans-boundary regulation of trade and surveillance of potential pathways of transmission.
