Abstract: An ecological survey was conducted along a stretch of beach in southern Monterey Bay to determine the distribution of sandy beach macrofauna with repsect to a lateral wave action gradient, and other physical gradients. Biological and physical studies were performed along six intertidal transects during the spring of 1972. Sand particle size was shown to be directly correlated with wave action, and intertidial water and organic carbon content were inversely correlated. Species diversity and population densities varied inversely with wave action, particle size, and immersion frequency. Hypotheses concerning ecological stresses as applied to beach communities are offered.
