Choice of tree holes as oviposition sites by Kurixalus eiffingeri on Iriomote Island

Research on Kurixalus eiffingeri frogs on Iriomote Island, part of the UNESCO World Heritage Sites in Japan, reveals that these frogs prefer tree holes for oviposition based on their height and opening angle. The study found that higher tree holes with larger opening angles were more frequently used, likely due to reduced predation risk. This preference contrasts with findings from Taiwan, where height was the primary factor, suggesting that environmental differences may influence oviposition site selection in this species. The study analyzed eight tree hole variables, identifying height above ground and opening angle as key factors in the best predictive model.
