Kenneth S. Norris Rancho Marino Reserve

22 Jan, 03 AM - 23 Jan, 09 AM

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 that are accessible to recreational visitors and open to collecting will be chosen for similarity in topography, wave exposure and other factors that influence community structure, at a range of distances from the protected sites. 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 larval input of selected invertebrates using recruitment collectors. If a signal is detected showing recruitment enhanced near protected areas and declining at increasing distances from these areas, these patterns of recruitment will be used to infer realized dispersal distances of the study species. I will be conducting surveys for abundance and size structure of Lottia gigantea in the rocky intertidal areas in Rancho Marino reserve, and will be placing tiles as recruitment collectors in the high intertidal. These collectors will be periodically collected and replaced.
