Preventing parasite-induced extinction of the San Miguel Island fox

 Since the recent appearance of an acanthocephalan parasite in the wild population, SMI fox reproductive success has been very low and mortalities have increased dramatically. The goal of this study is to understand the parasitological impacts of the SMI fox and develop a conservation management plan in conjunction with the Channel Islands National Park and USGS.


Ecology of amphibian parasites in Yosemite National Park

Amphibians are disappearing at an alarming rate due to multiple stressors, such as habitat loss, disease, and the introduction of non-native species. Within YNP, one current threat to amphibians is the American bullfrog, Lithobates [Rana] catesbeianus. Bullfrogs can introduce foreign parasites and support native parasites, altering natural host-parasite communities. This project aims to describe the parasite communities of both native and introduced amphibians. We coordinate with the Bullfrog Removal Program operated by YNP’s Aquatic Restoration Team.
