冲浪区水动力学变化沿着海岸线可能会影响交付的幼虫和浮游动物的补贴潮间带社区，因此，强度的沉降后的相互作用，生长和繁殖的滤食性基础物种和反食鱼类。我们调查了浮游动物组合进入加州沙城的裂缝通道、更具耗散性的海滩的宽冲浪区和附近卡梅尔河州立海滩的陡峭反射性海滩的窄冲浪区的能力。一个月的每一天，我们调查了浮游动物内部和外部的冲浪区和随之而来的幼虫定居的优势无脊椎动物在每个网站在这个上升流制度在岸上。在更耗散的冲浪区，所有的动物园更集中在冲浪区内比外面。许多类群增加了在冲浪区和主要的无脊椎动物在海滩上，Emerita analoga，解决了大量的时候，盛行的西北风放松和波浪小。在反射冲浪区，大多数类群的zooterters的浓度远远大于冲浪区内的外部，和许多类群增加冲浪区时，波小。两倍多的类群呈正相关的内部和外部的冲浪区的耗散比反射冲浪区，表明动物更自由地交换，虽然行为也发挥了作用。因此，碎波区水动力的空间和时间变化可能会调节浮游动物食物和幼体新兵的补贴，近岸社区的潜在级联效应，对社区动态和结构。
Surf zone hydrodynamics vary along shorelines potentially affecting the delivery of larvae and zooplankton subsidies to intertidal communities, and, hence, the intensity of postsettlement interactions, growth and reproduction of filter‐feeding foundation species and planktivorous fishes. We investigated the ability of zooplankton assemblages to enter the wide surf zone of the rip‐channeled, more dissipative beach at Sand City, California, and the narrow surf zone of the steep reflective beach at nearby Carmel River State Beach. Every day for a month, we surveyed zooplankton inside and outside the surf zone and concomitant larval settlement of the dominant invertebrate onshore at each site in this upwelling regime. At the more dissipative surf zone, all zooplankters were far more concentrated inside than outside the surf zone. Many taxa increased in the surf zone and the predominant invertebrate on beaches, Emerita analoga, settled abundantly when prevailing northwesterly winds relaxed and waves were small. At the reflective surf zone, concentrations of zooplankters of most taxa were far greater outside than inside the surf zone, and many taxa increased in the surf zone when waves were small. Twice as many taxa were positively correlated inside and outside the surf zone at the dissipative than the reflective surf zone, indicating that zooplankters were more freely exchanged although behavior also played a role. Thus, spatial and temporal variation in surf zone hydrodynamics may regulate subsidies of zooplankton food and larval recruits to nearshore communities with potential cascading effects on community dynamics and structure.
