Vocal networks remain stable after a disturbance in Emei music frogs

Social network analysis has been widely used to investigate the dynamics of social interactions and the evolution of social complexity across a range of taxa. Anuran species are highly dependent on vocal communication in mate choice; however, these species have rarely been the subject of social network analysis. The present study used social network analysis to investigate whether vocal network structures are consistent in Emei music frog (Babina daunchina) after the introduction of a simulated exotic rival of varying competitiveness into the social group. We broadcasted six categories of artificial calls (either highly sexually attractive calls produced from inside male nests or calls of low sexual attractiveness produced outside nests with three, five or seven notes, respectively) to simulate an intruder with different levels of competitiveness. We then constructed vocal networks for two time periods (before and after the disturbance) and quantified three network metrics (strength, cl...社会网络分析（Social Network Analysis）已被广泛应用于探究多个生物类群中社会互动的动态变化与社会复杂性的演化历程。无尾两栖类（Anuran）在配偶选择过程中高度依赖鸣声通讯，但此类群极少被作为社会网络分析的研究对象。本研究采用社会网络分析方法，探究峨眉弹琴蛙（Babina daunchina）在社交群体中引入不同竞争力水平的模拟外来竞争者后，其声学网络结构是否保持稳定。我们播放了六类人工模拟鸣声：一类为雄性巢穴内发出的高性吸引力鸣声，其余类群分别为巢穴外发出、具有3、5、7个音节的低性吸引力鸣声，以此模拟不同竞争力水平的入侵个体。随后我们基于干扰前后两个时间段构建声学网络，并量化了三项网络指标（强度、聚类...
