Extensive occurrence of the amphibian chytrid fungus in the Albertine Rift, a Central African amphibian hotspot
Recent surveys for the amphibian chytrid fungus (Batrachochytrium dendrobatidis, Bd) in Africa have documented the infectious disease in frogs and caecilians from forested habitats in multiple areas of Central and East Africa. We tested 166 frogs for the presence of Bd from 45 localities representing a diverse array of habitats and elevations (793–2852 m.a.s.l.) in the Albertine Rift (AR) region of eastern Democratic Republic of the Congo during four field seasons from 2008–2011. Fifty-eight of these frogs were positive, for an overall Bd-prevalence of 34.9%. Three genera of frogs (Callixalus, Chrysobatrachus and Nectophryne) are reported to be Bd positive for the first time. Behavioural observations of Bd-positive frogs calling for mates and basking suggest the AR amphibian fauna was not severely affected by chytridiomycosis during the survey. Given the enormous levels of endemism and conservation value of the AR amphibian fauna, additional studies of Bd should focus on the region.

More about this publication?
- The Herpetological Journal is an international scientific journal that publishes papers on the natural history of amphibians and reptiles. Experimental, observational and theoretical studies are published along with reviews and book reviews. Faunistic lists, letters and results of general surveys are not published unless they shed light on herpetological problems of wider significance.
