Measure marked individuals and survey plots. Measure tagged individuals and survey plots. I will tag 40 individuals of Pelvetiospsis, Hesperophycus, Silvetia using colored zip ties to monitor mortality, growth, and reproduction. I will clip 0.5 g samples of rockweeds and collect water samples. The goal of my research is to address the question: What are the abiotic and biotic factors that determine the communities that are associated with three rockweed species (Hesperophycus, Silvetia, and Pelvetiopsis) along the California rocky shore. To address this question I will travel to nine locations that span the California coast from San Diego County to Humboldt County. At each site I will measure seawater nutrient availability, salinity, and water flow. I will use weather station data (PRISM) to determine air temperatures and buoy data (NOAA) to determine water temperatures at each site. At each location, I will survey the communities associated with each rockweed species by estimating percent cover of sessile species and counting mobile species. These data will be used to determine the biotic associations that are being formed by individual species at each location. Following surveys, I will remove rockweed individuals from the upper, middle and lower parts of the tidal distribution. These individuals will be brought back to the lab to determine C:N ratios and nutrient uptake rates.
