Collaborative Research: Characterization of Aquatic Odor Signals Used for Chemosensory Orientation by Marine Crustaceans

在许多动物的生活中，化学信号在寻找食物、选择栖息地和配偶以及躲避捕食者方面起着重要作用。研究表明，底栖动物在几厘米到几米的距离内可以探测到其他动物或食物来源产生的化学信号并作出反应。本研究将测试一个假设，即气味在电流中浓度分布的微观尺度模式为动物提供了气味来源方向的信息。将进行实验室和现场实验工作，以描述和量化水生气味羽流中化学信号的分布，以及甲壳类动物对这些羽流的行为反应。＊＊＊

9315083 Atema Chemical signals play an important role in the lives of many animals for orientation to food, selection of habitats and mates, and avoidance of predators. It has been shown that benthic animals detect and respond to chemical signals produced by other animals or food sources at distances of centimeters to many meters. This study will test the hypothesize that the micro- scale pattern of concentration distribution of odors in a current provides information that is used by animals for orientation toward the odor source. Laboratory and in situ experimental work will be carried out to describe and quantify the distribution of chemical signals in aquatic odor plumes, and the behavioral responses of crustaceans to those plumes. ***
