Abstract
We assessed the potential impacts of the emergent fungal pathogen, Batrachochytrium salamandrivorans (Bsal), on salamander populations in Costa Rica by conducting pathogen surveillance and generating an ecological niche model (ENM) to predict areas at high risk of Bsal introduction. Across one year, we surveyed for Bsal, B. dendrobatidis, and Ranavirus in highland salamanders (n=100) in Cerro de la Muerte and el Parque Nacional Volcan Poas. We did not detect any of the above pathogens in our study specimens. Though we did not detect Bsal in our study, our ENM predicted that a large portion of Costa Rica’s landmass (22.82%) is at least moderately ecologically suitable to Bsal. Additionally, our ENM identified multiple locations throughout Costa Rica where moderate/high Bsal suitability overlaps with high salamander biodiversity and/or high human visitation. We encourage extensive monitoring and research at these locations with goals of early Bsal detection and introduction mitigation.
