Living in the city: Angiostrongylus cantonensis is a novel threat to an urban population of Florida burrowing owls (Athene cunicularia floridana) in south Florida Open
Background: Angiostrongylus cantonensis, the rat lungworm, is a metastrongyloid parasite that uses rodents as definitive hosts, mollusks as intermediate hosts, and a wide range of invertebrate and vertebrate species as paratenic hosts. Alt…

Evaluating translocation success of wild eastern hellbenders (Cryptobranchus alleganiensis alleganiensis) in Blue Ridge Ecoregion streams using pre- and post-translocation home range sizes and movement metrics Open
Translocations of freshwater species have become a widespread conservation strategy to mitigate the impacts of habitat fragmentation, yet they are not often rigorously monitored using animal movement data to determine their success. We dem…

Validation of an environmental DNA protocol to detect a stream‐breeding amphibian, the Streamside Salamander (<i>Ambystoma barbouri</i>) Open
Environmental DNA (eDNA), or DNA that is shed into the environment by an organism, can be used to detect the presence of cryptic species. However, eDNA methodology requires validation of an assay in both laboratory and field environments. …
