Recruitment of pelagic larvae plays a fundamental role in benthic marine populations, yet the sources and destinations of recruits are unknown for nearly all marine species. Because endemic species rely on retention of locally spawned larvae, they provide a novel opportunity for investigating the mechanisms allowing self-recruitment. I propose to compare the life histories and microchemical signatures in larval otoliths of endemic and closely related non-endemic reef fishes to determine the mechanisms and prevalence of self-recruitment. The results will broaden our understanding of how marine populations are replenished, information critically needed for marine conservation and resource management.

孢子幼虫的招募在底栖海洋人群中起着基本作用，但几乎所有海洋物种的新兵的来源和目的地都不为人所知。由于特有物种依赖于局部产卵幼虫的保留，因此它们为研究允许自我恢复的机制提供了新的机会。 我建议比较流行性和密切相关的非流行礁鱼的幼体耳石中的生命史和微化学特征，以确定自我招募的机制和流行率。结果将扩大我们对如何补充海洋人群的理解，海洋保护和资源管理至关重要的信息。
