摘      要：Density-dependent non-monotonic species interactions are important in maintaining ecosystem stability and function,but empirical evidences are still ***,as both seed dispersers and seed predators,have dual effects on plant regeneration and may result in non-monotonic rodent-plant *** to the non-monotonic models,the relative positive or negative effects of rodents on seedling establishment can be measured based on the positive or negative association of seedling recruitment rate and rodent *** this study,we investigated the fates of acorns of Quercus serrata by tracking tagged seeds on 21 fragmented subtropical islands in the Thousand Island Lake,*** found that the proportion of germinated seeds of all released seeds showed a dome-shaped association with rodent abundance per *** proportion of removed seeds and cached seeds showed a saturated-and a weak dome-shaped association with rodent abundance per seed,*** results demonstrated a clear empirical evidence that rodent abundance per seed triggered a switch between the relative mutualism and predation in a rodent-seed *** study implied that the observed non-monotonic interactions between plants and animals may play a significant role in maintaining biodiversity and ecosystem *** appeal for more investigations of the complex non-monotonic interactions in various ecosystems.
