Postdoctoral Research Fellowship in Biosciences Related to the Environment for FY 1997

摘要DBI 9750291卡罗尔·E·李这一行动资助了美国国家科学基金会1997年与环境相关的生物科学博士后研究奖学金。这一奖学金为研究员提供了一个在博士学位之外获得额外科学培训的机会，并在任何生物领域的分子、细胞、组织、种群、社区和/或生态系统层面上以创新和富有想象力的方式探索生物体与其环境之间相互作用的基本机制，这一领域得到了国家科学基金会生物科学局的支持。每个研究金资助一项研究和培训计划，该计划将在一个赞助实验室进行。该奖学金的研究和培训计划名为“栖息地转变期间的生理学进化”。它的副标题是“一种普通的甲壳类动物反复入侵淡水”。所有的动物门都是在海洋中进化的，大多数已经成功地过渡到淡水中。这种转变需要适应离子和渗透的变化。近些年来，甲壳类桡足类Eurytemora affinis已多次从咸水中独立入侵淡水水库。实验旨在通过结合生理和系统发育信息来确定在这些重复的栖息地转变过程中体液调节的变化。人们正在寻求关于生物地理转变期间生理学如何进化以及物种如何成功入侵新栖息地的见解。

Abstract DBI 9750291 Carol E. Lee This action funds an NSF Postdoctoral Research Fellowship in Biosciences Related to the Environment for 1997. This fellowship provides an opportunity for the Fellow to gain additional scientific training beyond the doctoral degree and to pursue innovative and imaginative into the fundamental mechanisms underlying the interactions between organisms and their environment at the molecular, cellular, organismal, population, community and/or ecosystem level in any area of biology supported by the Directorate for Biological Sciences of the National Science Foundation. Each fellowship supports a research and training plan to be carried out in a sponsoring laboratory. The research and training plan for this fellowship is entitled "Evolution of physiology during habitat transitions." It is subtitled "Repeated invasion of fresh water by a common crustacean." All animal phyla evolved in the sea, and most have successfully made the transition to fresh water. This transition requires adapting to ionic and osmotic changes. The crustacean copepod Eurytemora affinis has recently invaded freshwater reservoirs from salt water multiple times independently. Experiments are designed to determine changes in body fluid regulation during these repeated habitat transitions by combining physiological and phylogenetic information. Insights are being sought on how physiology evolves during biogeographic transitions and how species successfully invade new habitats.
