The goal of this research is to characterize the mechanosensors on the first antenna of calanoid copepods and evaluate their importance for prey and predator detection. Behavioral and morphological analyses have indicated that mechanoreception may be critical to pelagic copepods for prey detection, predator avoidance and mate recognition. Yet mechanoreception in copepods has not been studied physiologically. Dr. Hartline and a collaborator at the State University of New York, Stony Brook will combine expertise in copepod ecology and crustacean neurophysiology to investigate the sensory capabilities of copepods physiologically, and to integrate the sensory physiology with data on their ecology. The basic objectives of this project are: 1. To characterize the physiological responses to quantified mechanical stimuli. 2. To relate the physiological data to the external and internal morphology of the sensors. 3. To determine intraspecific differences in physiological properties and relate these to differences in species ecology. 4. To measure behavioral responses to mechanical stimuli and relate these to the physiological properties and the species ecology.

这项研究的目标是表征桡足类第一天线上的机械传感器，并评估它们对于猎物和捕食者检测的重要性。 行为和形态学分析表明，机械感受可能对远洋桡足类动物检测猎物、躲避捕食者和识别配偶至关重要。 然而桡足类的机械感受尚未进行生理学研究。 Hartline 博士和纽约州立大学石溪分校的合作者将结合桡足类生态学和甲壳类神经生理学方面的专业知识，从生理角度研究桡足类的感觉能力，并将感觉生理学与其生态学数据相结合。 该项目的基本目标是： 1. 表征对量化机械刺激的生理反应。 2. 将生理数据与传感器的外部和内部形态相关联。 3. 确定种内生理特性的差异，并将这些差异与物种生态学的差异联系起来。 4. 测量对机械刺激的行为反应并将其与生理特性和物种生态联系起来。
