Sympatry of species has been a central debate in ecology for decades but the mechanisms that aloow coexistence are still heatedly disputed. The main paradigms include the importance of abiotic conditions, predation risk, and competition as determinants of community structure. In this study, we investigated oviposition-site selection of two anuran species, Asiatic toads and dark-spotted frogs , which coexist in southwestern China. We sampled the abiotic and biotic attributes of 36 B. gargarizans breeding sites and 34 adjacent unused sites, and 30 P. Nigroimaculata spawning sites and 36 nearby unused sites.
