We suggest that the spatial patterns of epifaunal
diversity may be maintained by a feedback mechanism involving the interaction of the increased biogenic structure of the high-diversity patches, which enhances larval recruitment or restricts the dispersal of propagules.
Shale fossils include epifaunal
and nektobenthic species that Conway Morris (1986) suggested had been accidentally included during the deposit formation.
Mytilus edulis galloprovincialis was the most abundant epifaunal
invertebrate at depths influenced by the LSL [ILLUSTRATION FOR FIGURES 3 and 4 OMITTED].

community: competitive hierarchies and competitive networks.
However, even as late as the Cretaceous, outer-shelf habitats retained prominent epifaunal
suspension-feeders reminiscent of the ecological modes, although not the taxa, of Paleozoic seas (Jablonski et al.
Effects of periodic hypoxia on mortality, feeding and predation in an estuarine epifaunal
Most investigations that quantify filter feeding have been concerned with epifaunal
organisms (including sessile, tube-dwelling, and free-living organisms) or infaunal forms that have part of their body or tube in direct contact with the epibenthos (examples include the bivalve Mya arenaria and the polychaete Chaetopterus) (Wildish and Kristmansoa, 1997).
After the acclimation period, oysters were soaked in 9:1 water--chlorine bleach (HOCl) solution, rinsed in freshwater, and scrubbed to remove epifaunal
and burrowing organisms.
biomasses were collected for subsequent laboratory analysis.
Adaptations to environmental oxygen levels in infaunal and epifaunal
In conclussion, the distribution and space-seasonal variations of epifaunal
species, according to Miron and Desroniers (1990), depend on the interaction among particular environmental factors and interacting biotic factors as well (Commito and Boncavage 1989).
75 m) separating cage top and bottom layers in our study means that this explanation is less likely than differences in epifaunal
settlement, possibly in response to light intensity.

The dense communities of epifaunal
brachiopods that dominated level-bottom, shallow-water habitats prior to the Permo-Triassic extinction are largely absent from recent seas (reviewed by Thayer, 1986; Rudwick, 1970), and numerous attempts have been made to explain this shift in abundance and diversity (Stanley, 1977; Vermeij, 1977; Gould and Calloway, 1980; Gilmour, 1981; Thayer, 1981, 1985, 1986; Valentine and Jablonski, 1983a; Law and Thayer, 1991; Rhodes and Thayer, 1991; Thayer and Allmon, 1991; Rhodes and Thompson, 1993).
