WHERE WE ARE NOW The frogs of Madagascar have been kept by zoological institutions for decades, though only a handful of particularly charismatic and colorful species are well represented. A review of ISIS and ZIMS databases found barely two dozen of the more than 300 frog spe- cies known from Madagascar kept in captivity (5, 6). Nearly all of these were frogs from four genera: Dyscophus, Heterixalus, Mantella, and Scaphiophryne. Even though the species kept at zoos abroad represent just a small portion of Madagascar’s amphibian diversity, important conservation research has been carried out with them. For instance, Bristol Zoo, Chester Zoo, Paignton Zoo and the Paris Zoo have partnered with the Technical University of Braunschweig and the Emergency Chytrid Cell of Madagascar to develop effec- tive probiotic treatment to address the threat of amphibian chytrid (7). More often zoological institutions maintain public exhibits of these species to raise awareness of the plight of amphibians as a whole and, in some cases, to draw attention to conservation issues in Madagascar. 1Amphibian Specialist Group – Madagascar, c/o Durrell Wildlife Conservation Trust; 2Durrell Wildlife Conservation Trust; 3Museo Regionale di Scienze Naturali, Via G.
