Asymmetric cross-strain protection for amphibians exposed to a fungal-metabolite prophylactic treatment

KM Barnett, D.J. Civitello, T.A. McMahon & S.E. Detmering
Chytridiomycosis, an infectious disease of amphibians caused by the fungal pathogen Batrachochytrium dendrobatidis (Bd), poses an imminent conservation threat. The global spread of Bd has led to mass mortality events in many amphibian species, resulting in at least 90 species’ extinctions to date. Exposure to Bd metabolites (i.e., non-infectious antigenic chemicals released by Bd) partially protects frogs during subsequent challenges with live Bd, suggesting its use as a prophylactic treatment and potential vaccine. However, we...

Conservation of Birds in Fragmented Landscapes Requires Protected Areas

For successful conservation of biodiversity, it is vital to know whether protected areas in increasingly fragmented landscapes effectively conserve species. However, how large habitat fragments must be and what level of protection is required to sustain species, remains poorly known. We compiled a global dataset on almost 2000 bird species in 741 forest fragments varying in size and protection status, and show that protection is associated with higher bird occurrence, especially for threatened species. Protection...
