In the mid-eulittoral, competition between Mytilus edulis and Semibalanus balanoides is the dominant biological interaction. Predation and herbivory are the main factors affecting space utilization (Menge and Sutherland, 1976; Menge, 1978a,b; Lubchenco, 1983; 1986). By clearing space, Nucella lapillus and other predators of Mytilus edulis allow the persistence of Fucus vesciculosus and Ascophyllum nodosum on semiprotected and protected sites, respectively (Keser and Larson, 1984a,b). 8 Schematic diagram showing the vertical distribution patterns of major taxa on northwest Atlantic shores.

When sea urchins are rare, communities of kelp and other macrophytes flourish. 9). 3 THE PACIFIC COAST OF NORTH AMERICA The northeast Pacific coastline stretches nearly 2000 km from Alaska (53°N) to the tip of Baja California (23°N). In the northeast Pacific, temperatures range from 5°C near the Aleutian Islands to 20°C near Baja California. Inshore temperatures are affected by coastal upwelling, a seasonal feature most prevalent off California and Baja California. Tides along the northeast Pacific coast are mixed semidiurnal: two highs and two lows occur in each lunar day, with successive high and low waters and successive low waters each having different heights.

Lower Eulittoral: All three barnacles that characterize the upper eulittoral extend somewhat into the lower eulittoral, where they are in competition with algal turfs and only flourish in clearings. Balanus glandula may be plentiful at the top of this zone, Tetraclita is often common, and Chthalamus dalli may form dense sheets at the bottom of the zone. As exposure increases, dense beds of mussels (Mytilus californianus) occur and may extend up into the lower part of the upper eulittoral. Another common clumpforming species is the goose-necked barnacle, Pollicipes polymerus.
