METHODS AND STUDY SITES. Fish communities were studied on rocky reefs at two locations in southern California: Santa Cruz Island (35°5′ N, °45′ W; see Schmitt and Holbrook, a, b; Holbrook et al., ) and the mainland coast at King Harbor (33°51′ N, °24′ W; see Functional structure of soft-bottom fish communities of the Southern California Shelf book and.

Although California halibut was not a member of a group in a recurrent group analysis of soft-bottom fishes on the southern California shelf (M.J.

Allen ), it was closely associated (Index of Affinity = –) with the white seaperch, walleye surfperch, black perch, and speckled sanddab. The earliest surveyors of the soft-bottom ichthy- ofauna of southern California (Gilbert,; Ulrey and Greeley ) used beam trawls as a sampling device.

However, since the s small otter trawls have been preferred (Mearns and Allen ) because they capture more species of fish and are less cumbersome to use.

The most abundant species was the speckled sanddab, Citharichthys stigmaeus.

Boesch () has reviewed the trophic interactions between soft- bottom benthic communities and bottom-feeding fish in the New York Bight. In examining changes in community structure in silt-clay facies, it is clear that responses to disturbance during the colonizing phase involve a shift from subsurface, deposit-feeding species to those.

The Cap de Creus Natura protection range is intended to extend the area of protection to approximately ha ( km 2) of offshore waters, covering the shelf, the shelf-break and the head of a submarine canyon in the region.

Common demersal fish such as Paralonchurus brasiliensis, Micropogonias furnieri, Ctenosciaena gracilicirrhus and Raja agassizi are active predators of the macrobenthic organisms in the Ubatuba region (Nonato et al., ), and constitute an important structural factor for benthic communities of sandy-muddy bottoms (Amaral & Migoto, ).

The installation of marine renewable energy (MRE) devices may alter marine habitats through mechanisms that induce physical change, such as modifying or eliminating species in a localized area, providing opportunities for colonization by new species, altering patterns of species succession, and inducing behavioral responses in marine organisms.

Christofoletti, Gustavo Fonseca, Gustavo M. Dias.The rigorous demonstration of truly stable alternate community states is elusive in marine ecosystems and might remain so for some time.

Examples of marine community states that have shifted are nevertheless increasingly conspicuous. The growing concern over these altered community states is often related to questions of persistence and reversibility, especially when these shifted states are Cited by:
