These species represent and of the respective 3-yr totals (Livingston et al . 1976). show distinct patterns of relative abundance throuqh a given seasonal period. Various independent ecological factors operate to determine the temporal distribution of the dominant estuarine organisms. Biological functions, such as adaptive response to the physical and trophic environment, determine distributional patterns, thereby allowing a somewhat orderly temooral succession of dominant forms within certain broad trophic spectra. Patterns of reproduction of various dominant estuarine species have evolved in such a way as to permit long- term partitioning of the estuarine environment. Superimposed on these patterns of response are varying levels of resource division based on vertical and horizontal distribution of the component 96
