Breeding phenology and larval distribution of amphibians in a Mediterranean pond network with unpredictable hydrology

摘要: Understanding spatial and temporal breeding patterns in Mediterranean amphibian communities is urgent considering the rate of habitat loss. Breeding phenology selection by amphibians were analysed through monthly occurrence larvae a mosaic 198 temporary ponds during three years. A generalized linear model (GLM) coupled with principal component analysis showed that, for almost all species, was significantly positively correlated to pond depth. In addition, openness negatively affected presence some species. Temporal varied among Some species exhibited flexibility their date (Pelobates cultripes, Pelodytes punctatus, Hyla meridionalis, Rana perezi), while others did not (Triturus marmoratus, Triturus helveticus, Bufo calamita). When faced inter-annual hydrological variability, first group had more constant success than second. Variable conditions caused differential larval between These fluctuations might favour long-term persistence whole community. We finally discuss implications our results management habitats region.
