Breeding phenology of amphibians in a Mediterranean ephemeral stream (Ardèche, France)

We present the results of monitoring breeding phenology an assemblage eight species amphibians in a Mediterranean ephemeral stream, located Ardèche department, France. For most species, during 11 consecutive years, was rather constant from year to year, which is unusual temporary ponds. The occurrence summer not rare for three species: Pelobates cultripes (Cuvier, 1829), Pelodytes punctatus (Daudin, 1803) and Hyla meridionalis Böttger, 1874. Breeding linked rewetting events caused by active karst resurgences, fuelled periods intense rainfall episodes called “cévenol” episodes. document first time triannual (spring, summer, autumn), situ record short tadpole development period, concerning particularly P. cultripes. ecological factors can explain this richness these observations are outlined. In conclusion, we encourage conservation amphibian communities streams, as natural scientific interests type habitat often underestimated.
