摘要
Noise pollution has been shown to affect wild animals in various ways,but little is known about its consequences at the community level.Investigating animals’overall vocal responses to noise across multiple sympatric species can reveal the complex nature of noise impacts butis challenging.In this study,we employed social network analysis(SNA)to evaluate how anuran communities and populations vary their calling behaviors in response to aircraft noise.SNA of anuran communities revealed that conspecifc individuals increase the aggregation of theirspectral(i.e.,minimum frequency,maximum frequency,and dominant frequency),temporal(call duration,call rate,and call effort),and overallspectral-temporal features as an airplane passes through.SNA of populations also revealed that anurans could increase the interindividual similarity of multiple call characteristics in response to airplane noise.Furthermore,our network analysis of multiple species and multiple call traitsrevealed an effect of noise in species whose calling behavior did not change in previous separate analyses of each species and single traits.Thisstudy suggests that noise pollution may change the pattern of combined acoustic properties at the community level.Our fndings highlight theimportance of integrated methods and theories for understanding the ecological consequences of noise pollution in future studies.
