动物使用各种信号形式相互交流,其中任何一种都可以向非预期的接收者或窃听者提供有用的信息。化学信号的衰减是一种普遍的现象,但它在塑造多物种组合行为中的作用却知之甚少。在这里,我们测试的假设,工人的多个新热带区蚂蚁物种改变他们的行为时,暴露在气味的共同冠层蚂蚁,阿兹特克三角。我们将16种冠层蚂蚁(5个亚科)的工蚁暴露于三角蚁警报信息素,并比较它们对对照处理(环境空气)中蚂蚁行为的行为反应。与对照相比,七种植物对三角藻表现出不同的反应。最常见的行为反应是增加触角和运行。这项研究的结果表明,窃听异源警报信号,使蚂蚁,以避免广义的威胁或消极的相互作用与aggressiveA.trigonaworkers。这样的窃听大概是有选择性的优势,并可能确定当地的树栖蚂蚁物种分布和种间差异,在森林冠层资源的访问。
Animals communicate with each other using a variety of signal modalities, any of which can provide useful information to non-intended receivers, or eavesdroppers. Eavesdropping on chemical signals is a widespread phenomenon but its role in shaping the behavior of multi-species assemblages is poorly known. Here, we tested the hypothesis that workers of multiple Neotropical ant species change their behaviors when exposed to odors of the common canopy ant,Azteca trigona. We exposed workers of 16 canopy ant species (five subfamilies) toA.trigonaalarm pheromones and compared their behavioral responses to the behavior of ants in control treatments (ambient air). Seven species showed distinct responses toA.trigonaodors relative to the control. The most common behavioral responses were increased antennation and running. The results of this study suggest that eavesdropping on heterospecific alarm signals allows ants to avoid generalized threats or negative interactions with aggressiveA.trigonaworkers. Such eavesdropping presumably is selectively advantageous and may determine local arboreal ant species distributions and interspecific differences in access to resources in the forest canopy.
