The Effects of Geology on Intertidal Community Structure
The extensive anthropogenic armoring of the shoreline in California changes the substrate available to settling invertebrate larvae and algal spores that are passively distributed in the ocean currents. Rock type available to settlers likely influences the community structure in the intertidal, as rock characteristics have been shown to favor or inhibit settlement. Much research has been done examining the mechanisms that determine intertidal community patterns, but the role of rock type has been largely neglected. My goals are to: 1) determine if there is a difference in community assemblages relating to different rock types, and if so, 2) demonstrate the mechanisms responsible for these differences, and 3) link those patterns to life history characteristics of selected species. I am conducting two studies — the first comparing two sites with armored, rip-rapped shorelines and the second using settling plates at two sites with different bedrock within Monterey Bay, California. The intertidal community structure on the armored rocks and settling plates shows different patterns for certain species distributions, and warrants further examination. These studies will help in predicting how continued armoring of the shoreline will affect species assemblages, as well as enhance our understanding of why there are different intertidal community assemblages at different sites along the coast.
