Organisms living in the marine rocky intertidal zone compete for space. This, together with predation, physical disruption, and differing species tolerances to physiological stress, explains the structure of the ecological communities at some sites. At other sites the supply of larvae is limiting, and events in the offshore waters, such as wind-driven upwelling, explain the composition of intertidal communities. Whether the community ecology at a site is governed by adult-adult interactions within the site, or by limitations to the supply of larvae reaching the site, is determined by the regional pattern of circulation in the coastal waters. Models combining larval circulation with adult interactions can potentially forecast population fluctuations. These findings illustrate how processes in different ecological habitats are coupled.
生活在海洋岩石潮间带的生物会争夺空间。这与捕食、物理干扰以及不同物种对生理压力的耐受性共同解释了某些地点生态群落的结构。在其他地点，幼虫的供应是有限的，而近海水域的事件，如风生上升流，则解释了潮间带群落的组成。一个地点的群落生态是由该地点内成年个体之间的相互作用所支配，还是由到达该地点的幼虫供应限制所决定，取决于沿海水域的区域环流模式。将幼虫环流与成年个体相互作用相结合的模型有可能预测种群波动。这些发现说明了不同生态栖息地中的过程是如何相互关联的。
