Within the bathym?trie range of the species (about ?30 m to +4 m; Chan, 1973) the mussels occur at highest density in the middle intertidal zone, at approximately +1.5 m to +3.0 m (Paine, 1974). M.

The results can be summarized as follows: 1. The California mussel (Mytilus californianus) is a large edible mussel, a marine bivalve mollusk in the family Mytilidae. In some long-term studies of Mytilus californianus it was observed that gaps could continue to increase in size post-disturbance due to wave action and predation (Paine & Levin, 1981; Brosnan & Crumrine, 1994; Smith & Murray, 2005) potentially due to the weakening of the byssus threads leaving them more vulnerable to environmental conditions (Denny 1987). transverse Habitat Mytilus californianus, California Mussels, form mussel beds, and are abundant on surf-exposed rocks and pier pilings.Found mainly in upper-middle intertidal zone on outer coast and can be found subtidal and offshore to 24 m (depth). Mats can form habitats for more than 100 other species (Ref. Mature M. californianus Enlarge image. Nevertheless, the above evidence suggests that mussel beds are potentially intolerant of the effects of trampling, depending on trampling intensity and frequency. We examine biophysical mechanisms responsible for patchy mortality in beds of the competitively dominant ecosystem engineer, the marine mussel Mytilus californianus, on the west coast of the United States.
