Spatial and temporal patterns of recruitment can strongly influence both the abundance and distribution of animals, as well as the evolution of life history characteristics. Larvae of most benthic and demersal fishes arrive on reefs with well-developed swimming and sensory capabilities and therefore, have the potential to strongly influence the pattern of recruitment by controlling where and when they settle. This research will experimentally examine the role of larval behavior in determining the pattern of settlement of a benthic fish common to oyster reefs. The naked goby was chosen because its larvae undergo a demersal schooling phase prior to settlement. Larvae of this species are extremely abundant and can be easily observed. Dr. Palmer and collaborators will focus on two aspects of larval behavior (1) how larval behavior influences pre-settlement distribution and dispersion patterns, in turn, influence spatial patterns of settlement. These two processes are extremely important to the ultimate patterns of recruitment because they can determine which other species influence larval survival and movement, the spatial distribution of recruits, the need for post-settlement dispersal and the importance of density-dependent interactions.

招募的空间和时间模式可以强烈影响动物的丰度和分布以及生活历史特征的进化。 大多数底栖鱼类和塞尔萨尔鱼类的幼虫以发达的游泳和感觉能力到达礁石上，因此有可能通过控制何时何地定居，从而强烈影响招募模式。 这项研究将在实验中研究幼虫行为在确定牡蛎珊瑚礁共有的底栖鱼类定居模式中的作用。 之所以选择赤裸的戈比，是因为其幼虫在定居前经历了塞尔萨尔教育阶段。 该物种的幼虫非常丰富，可以很容易地观察到。 帕尔默博士和合作者将重点关注幼虫行为的两个方面（1）幼虫行为如何影响安排前的分布和分散模式，进而影响定居点的空间模式。 这两个过程对招募的最终模式非常重要，因为它们可以确定哪些其他物种会影响幼虫的生存和运动，募集的空间分布，对分配后分散的需求以及密度依赖性相互作用的重要性。
