AN ECOLOGICAL SURVEY OF A SANDY BEACH
Abstract
An ecological survey of a sandy beach was made to determine relationships between population densities and sand grain size distributions, season and height above the tidal datum plane (MLLW). Fifteen species of invertebrates in four phyla were collected. Four zones relative to tidal datum and two major habitats - protected outer coast sandy beach and outer coast sandy beach - were defined. Nephtys caecoides, Nephtys californiensis and Archaeomysis maculata showed distinctive distribution patterns relative to mean grain size which require further investigation.
