This study will compare a variety of rocky intertidal sites with a gradient of human visitation and use. A set of well-protected sites spanning the California coastline will form the focal point of the study, while reference sites in nearby areas, accessible to recreational visitors and open to collecting, will be chosen for similarity in topography, wave exposure, and other factors that may influence community structure. At each site I will measure population abundance and size structure to confirm that differences exist between areas with varying levels of human impact, and measure recruitment of selected invertebrates. Patterns of recruitment will be used to infer dispersal distances from sites with higher densities and more large individuals to surrounding areas. Species: A number of intertidal species, representing a range of dispersal regimes, will be selected. These species are subject to collection for recreation, food, or bait, or affected by trampling. Many of these species have already been shown to be reduced in abundance or size in exploited areas. Potential species of interest include Lottia gigantea, Tegula funebralis, Stenoplax conspicua, Tonicella lineata, Asterina miniata, Astrea undosa, Strongylocentrotus purpuratus, and Mytilus californianus.
