Population Regulation in a Temperate Reef Fish System

生物海洋学和海洋生态学的一个基本主题是了解海洋生物系统如何响应各种环境和生物过程和扰动。 目前这些领域的大部分研究兴趣集中在影响海洋生态系统内种群动态和调节的过程上。 该延续项目重点关注如何监管温带珊瑚礁鱼类种群的基本问题。 特别是，博士。施密特和霍尔布鲁克将探讨这些鱼类种群在多大程度上受平衡或非平衡动态控制，以及导致其调节的过程和机制。 他们将讨论密度依赖性是否以及如何在鱼类的不同生命阶段发挥作用。 所研究的条纹鲈鱼（Embiotoca Lateris）和黑鲈鱼（E. jacksoni）代表了一类海洋生物，其中的局部补充可能在某种程度上与新繁殖体的产生相结合。 因此，通过这项研究获得的信息将有助于更广泛地了解环境和生态过程如何影响生物耦合系统的动态和调节。

A fundamental theme in biological oceanography and marine ecology is to understand how marine biological systems respond to various environmental and biological processes and perturbations. Much of the current research interest in these fields is on the processes that affect the dynamics and regulation of component populations within marine ecosystems. This continuation project focuses on the essential issue of how populations of temperate reef fish are regulated. In particular, Drs. Schmitt and Holbrook will address the extent to which populations of these fishes are governed by equilibrium or non-equilibrium dynamics, together with the processes and mechanisms that result in their regulation. They will address whether and how density- dependence may (or may not) operate at different life stages of the fishes. The fishes investigated, striped surfperch (Embiotoca lateralis) and black surfperch (E. jacksoni), represent a class of marine organisms where local recruitment may be coupled to some extent with production of new propagules. As such, information gained by this research will contribute to a broader understanding of how environmental and ecological processes can affect dynamics and regulation in biologically coupled systems.
