Living organisms are exposed to environmental cycles that result from the movement of the planet, as well as the movement of the moon. Most species have adapted to the solar day and the alternation of seasons and show oscillations in their physiology and behavior that are in synchrony with these cycles. Furthermore, species living at the seashore show biological oscillations in synchrony with the tidal cycle. Many of these daily and tidal biological oscillations are generated by biological clocks, which are endogenous biological processes that can oscillate in synchrony with the environment. Very little is known about the neural and molecular components that constitute these biological clocks in crustaceans of coastal habitats. The main goal of this project is to characterize the biological clocks responsible for daily and tidal rhythmicity in crustaceans living in coastal areas. Techniques will be used that involve isolation of specific genes involved in the clock mechanism and the study of behavioral rhythmicity in the laboratory. The studies will contribute to the understanding of biological timing systems and it will more specifically establish how species inhabiting the seashore have adapted to the environmental changes that result from the solar day and the tidal cycles. This project provides an excellent opportunity to study biological rhythms in a unique costal environment, namely the Pacific Northwest Coast and will provide a forum for both graduate and undergraduate student research training, by exploiting the research facilities at University of Washington and at Friday Harbor Laboratories.

生物体暴露于由行星运动和月球运动引起的环境周期中。大多数物种已经适应了太阳日和季节的交替，并表现出与这些周期同步的生理和行为振荡。此外，生活在海滨的物种显示出与潮汐周期同步的生物振荡。许多这些每日和潮汐生物振荡是由生物钟产生的，生物钟是可以与环境同步振荡的内源性生物过程。很少有人知道的神经和分子组成部分，构成这些生物钟的甲壳类动物的沿海栖息地。该项目的主要目标是描述生活在沿海地区的甲壳类动物的生物钟，这些生物钟负责日常和潮汐节律。将使用的技术，涉及分离的特定基因参与的时钟机制和行为的节奏在实验室中的研究。这些研究将有助于了解生物计时系统，并将更具体地确定居住在海滨的物种如何适应太阳日和潮汐周期造成的环境变化。这个项目提供了一个很好的机会，研究生物节律在一个独特的沿海环境，即太平洋西北海岸，并将提供一个论坛，研究生和本科生的研究培训，利用研究设施在华盛顿大学和星期五港实验室。
