COLLABORATIVE RESEARCH: Sensory Ecology of an Animal Communication Network

“合作研究：动物交流网络的感官生态学”（IBN 0239164/0238854）乔治W。Uetz，J. Andrew Roberts，辛辛那提大学大卫L.克拉克，阿尔马学院动物的沟通往往是多模式的，因为生产和检测的信号可能涉及几个感官模式。 引人注目的多模态信号可能被有意（潜在配偶）或无意（窃听竞争对手和捕食者）的接收器截获，信号行为的演变受到相互冲突的选择压力之间的权衡。 这项研究将通过实地观察、环境测量和实验室实验来研究窃听竞争对手和捕食者如何拦截和利用蜘蛛的求偶信号。 研究将探讨雄性狼蛛的视觉和振动信号如何受到复杂的森林地面环境的影响，并在潜在接收器的“通信网络”中传输。 多模态信号的“有效空间”或传输范围将在现场用计算机辅助照度分光光度法和激光多普勒振动记录进行测量。感官线索隔离和视频/音频播放实验将确定多种通信模式如何影响其他蜘蛛以及脊椎动物和无脊椎动物捕食者的信号检测。 总之，实地和实验室研究的结果将使我们更好地了解动物在复杂环境中的交流。来自一所大学和一所文科学院的研究人员之间的合作将通过博士后培训，两个机构的本科生参与研究以及与进行实地研究的环境教育中心建立研究和教育伙伴关系来促进教学，培训和学习。

"COLLABORATIVE RESEARCH: Sensory Ecology of an Animal Communication Network" (IBN 0239164/0238854)George W. Uetz, J. Andrew Roberts, University of Cincinnati David L. Clark, Alma CollegeAnimal communication is often multi-modal, as production and detection of signals may involve several sensory modes. Conspicuous, multi-modal signals may be intercepted by receivers that are intended (potential mates) or unintended (eavesdropping competitors and predators) and the evolution of signaling behavior is subject to trade-offs between conflicting selection pressures. This research will use field observation, environmental measurement and laboratory experimentation to examine how eavesdropping competitors and predators intercept and exploit the courtship signals of spiders. Studies will examine how visual and vibratory signals of male wolf spiders are influenced by the complex forest floor environment and transmitted within a "communication network" of potential receivers. The "active space", or transmission range of multi-modal signals will be measured in the field with computer-assisted illuminance spectrophotometry and laser doppler vibration recording. Sensory cue isolation and video/audio playback experiments will determine how multiple modes of communication influence signal detection by other spiders, as well as vertebrate and invertebrate predators. Taken together, results of field and laboratory studies will allow a better understanding of animal communication in a complex environment. Collaboration between researchers from a university and a liberal arts college will promote teaching, training and learning through post-doctoral training, involvement of undergraduate students from both institutions in the research, and a research and education partnership with the environmental education center where field research is done.
