The other stations cluster in the middle, with Station B most similar to Station A. Stations G and D, which both reside in small coves on different sides of Fiesta Island, also appear relatively similar to each other. The analysis of five stations in summer and winter months reveals seasonality in the faunal communities, but the back-bay/front-bay gradient observed in the overall MDS (Fig. 5B) is evident in both seasons. Station A had the highest similarity between the summer and winter months, while Station E had the lowest similarity. SIMPER analyses between stations A, B, and E (Table 2) demonstrate how differences in abundances of dominant species (Fig.'s 2 and 3) drive seasonal community dissimilarities. In summer months, M. senhousia is most important in driving differences among the three stations, and Praxillella pacifica distinguishes Stations A from both B and E. The polychaete Lumbrineris sp. was responsible for differences among all stations in both summer and winter. In winter, Diplo- cirrus sp. distinguishes the front-bay from the back-bay stations, and Phoronis sp. distinguishes Stations B from A and E. Examining all stations together, some general patterns emerge. The average within-year and between-year similarities (Table 1) were correlated (R-^ = using exponential regression), indicating that stations that were spatially variable at any one time also were variable over time. Also, suspension feeders showed relatively large temporal variability (Fig. 4), with an average coefficient of vari-.
