Morgan 9408951 The inability of investigators to track microscopic larvae of marine animals has impeded our understanding of planktonic processes that regulate larval supply to adult populations. This project will be to adapt techniques that have been used by entomologists to study dispersal by crustacean larvae. The study will determine the feasibility of tagging barnacle and crab larvae with rare earth elements (REE) by examining uptake and persistence of marker, levels of marker passed from females to larvae and variability of rare earth elements in larvae from natural populations. The success of adapting this technique for marine animals largely depends on whether or not REEs can be accumulated and retained by animals in seawater long enough to be useful as tracers of larval movements. ***

摩根9408951 研究人员无法追踪海洋动物的微观幼虫，这阻碍了我们对调节幼虫向成年种群供应的增殖过程的理解。 该项目将调整昆虫学家用来研究甲壳类幼虫扩散的技术。 该研究将通过检查标记物的吸收和持久性、从雌性传递到幼虫的标记物水平以及自然种群幼虫中稀土元素的变异性，确定用稀土元素（REE）标记藤壶和螃蟹幼虫的可行性。 将这种技术应用于海洋动物的成功在很大程度上取决于稀土元素是否能被动物在海水中积累和保留足够长的时间，以作为幼虫运动的示踪剂。 ***
