Infection with Batrachochytrium dendrobatidis is common in tropical lowland habitats: Implications for amphibian conservation. [PDF]
We conducted a survey testing for the fungal pathogen Batrachochytrium dendrobatidis (Bd) in four lowland sites in Costa Rica to identify local host‐pathogen dynamics and to describe the abiotic environment for this pathogen. We found evidence that lowland study sites exhibit enzootic dynamics with low infection intensity and moderate to high ...

Thermal tolerance in anuran embryos with different reproductive modes: relationship to altitude. [PDF]
Anurans are ectothermic animals very sensitive to temperature, mainly during the embryonic stage. In addition, environmental temperature decreases with altitude, and the amphibian fauna changes. Therefore, we studied the relationship between the embryonic thermal tolerances of twelve species of anurans and the temperatures of their microhabitat along ...
