In Focus: Lewanzik, D., Sundaramurthy, A. K., Goerlitz, H. R. (2019). Insectivorous bats integrate social information about species identity, conspecific activity and prey abundance to estimate cost-benefit ratio of interactions. Journal of Animal Ecology, 88, 1462-1473. Social interactions can generate social structures that shape the fate of individuals and populations. A key feature of social environments is the information produced by others. Whether actively shared or obtained via 'eavesdropping', individuals of many species use publically available information to guide their decision making in important ways. Lewanzik et al. (2019) explore social information use within and across several echolocating bat species. They experimentally manipulated the content of social information about prey abundance with playback experiments of echolocation calls. All species were found to use heterospecific and conspecific social information about conspecific activity levels and prey abundance. This is a rare experimental confirmation of social information use at a community level.
Lewanzik，D.，Sundaramurthy，A. K.，Goerlitz，H. R.（2019）。食虫蝙蝠整合有关物种身份、同种活动和猎物丰度的社会信息，以估计相互作用的成本效益比。动物生态学杂志，88，1462-1473。社会互动可以产生影响个体和种群命运的社会结构。社会环境的一个关键特征是他人产生的信息。许多物种的个体无论是主动共享还是通过“偷听”获得，都会以重要方式利用公开可用的信息来指导他们的决策。Lewanzik 等人（2019）在几种回声定位蝙蝠物种内和跨物种探索了社会信息的使用。他们通过回声定位叫声的回放实验来实验性地操纵关于猎物丰度的社会信息的内容。所有物种都被发现使用同种和同种活动水平以及猎物丰度的异源和同源社会信息。这是对社区层面社会信息使用的罕见实验验证。
