Warner 9615516 Results of studies on biogeography and population ecology of marine organisms suggest that larval transport and recruitment are important process in determining the distribution and persistence of adult populations. Our understanding of these processes, however, is severely limited by our inability to determine the sources and subsequent dispersal patterns of marine larvae. Dr. Warner hypothesizes that spatial variation in water chemistry among potential source populations, both in terms of isotopic ratios and elemental concentrations, can be used to discriminate between recruitment events resulting from larval retention versus dispersal between populations. This can be achieved if larvae permanently record the environmental signature of their location of origin. He will test this hypothesis by comparing the otolith chemical composition of newly settled recruits to resident adults from populations with different chemical environments. ***

华纳9615516海洋生物的生物地理学和种群生态学研究结果表明，幼虫的运输和招聘是确定成年人种群的分布和持久性的重要过程。但是，我们对这些过程的理解受到我们无法确定海洋幼虫的来源和后续分散模式的严重限制。华纳博士假设，在同位素比和元素浓度方面，潜在源人群之间水化学的空间变化可用于区分幼体保留率与种群之间的分散性产生的募集事件。如果幼虫永久记录其原产地点的环境签名，则可以实现这一目标。他将通过比较来自具有不同化学环境的人群的居民成年人的耳石化学成分来检验这一假设。 ***
