摘　　要：背景噪声会降低发声动物声音通讯质量,同时降低特定个体被捕食的风险。因此,发声动物如何响应被噪声掩蔽的同种声音是事关其生存与繁殖的决策过程,但尚不清楚雌雄两性如何响应被掩蔽的同种声音以及其响应是否存在性别差异。以安徽树蛙(Zhangixalus zhoukaiyae)为模型,回放同种广告鸣叫、异种广告鸣叫、白噪声及同种广告鸣叫与其他声音的组合声音,记录雌雄两性的行为响应,探究非同种声音对安徽树蛙雌性选择和雄性竞争的影响。结果显示:(1)雌性安徽树蛙更偏爱信噪比高的同种广告鸣叫;(2)雄性能动态调整竞争策略,且更偏爱响应被异种广告鸣叫重叠的同种广告鸣叫;(3)雌雄两性行为响应存在差异,此差异可能源自自然选择和性选择双重压力的综合作用。研究结果有助于更好地理解不同噪声对动物行为决策及种群分布格局的影响,并为物种保护提供有益参考。Background noise reduces the quality of acoustic communication in vocal animals,and simultaneously reduces the risk of predation on specific individuals.Therefore,how to respond to conspecifics sounds masked by noise is a decision-making process related to survival and reproduction in vocal animals.However,it is unclear how males and fe⁃males respond to the masked conspecific sounds and whether there are sex differences in their responses.In the study,we utilized Anhui tree frogs(Zhangixalus zhoukaiyae)as a model and played back conspecific advertisement calls,heterospe⁃cific advertisement calls,white noise,as well as combined sounds of conspecific advertisement calls with other sounds.Subsequently,we recorded the behavioral responses of males and females,to investigate the effects of non-conspecifics sounds on female choice and male-male competition in Anhui tree frogs.The results showed that:(1)Female Anhui tree frogs exhibited a preference for conspecific advertisement calls with high signal-to-noise ratio.(2)Males displayed the abil⁃ity to dynamically adjust their competitive strategies and preferred to respond to conspecific advertisement calls overlapped by heterospecific advertisement calls.(3)There were differences in the behavioral responses of males and females,which might be stem from the combined effects of the dual pressures of natural selection and sexual selection.This study en⁃hances our comprehension of the impact of different noises on animal behavior and population distribution patterns,also provides a valuable reference for species conservation.
