Are Infaunal Predators Important in Structuring Marine Soft-Bottom Communities?

Benthic infaunal community structuring in an acidified tropical estuarine system

BACKGROUND Recent studies suggest that increasing ocean acidification (OA) should have strong direct and indirect influences on marine invertebrates. While most theory and application for OA is based on relatively physically-stable oceanic ecological systems, less is known about the effects of acidification on nearshore and estuarine systems. Here, we investigated the structuring of a benthic i...

Importance of predatory infauna in marine soft-sediment communities

Ambrose (1984a) suggested that a 3-way interactive model should be applied to marine infaunal communities having the levels of epibenttuc predators, predatory infauna and nonpredatory infauna. It is shown that the 3-level interactive model incorporates the implicit, unstated assumption that epibenthlc predators preferentially prey on predatory infauna. A review of the literature reveals that th...

Competition and Predation in Marine Soft-sediment Communities

One of the major goals of community ecology is to understand how interactions among the resident organisms affect their distribution and abundance. For terrestrial and rocky intertidal communities competition and predation clearly can play pivotal roles in community organization (28, 47, 84). The importance of biological processes in organizing marine soft-sediment communities is not as well un...

Discriminating mesozooplankton communities in Bushehr marine coastal ecosystems- Persian Gulf

Coastal ecosystems of Bushehr are shallow environments subject to human impacts, including shrimp aquaculture and urban expansion activities. A spatial-temporal study was conducted in order to assess the actual ecological status of the creeks, estuary and marine sites on the basis of their taxonomic composition and density of mesozooplankton. Zooplankton species distribution and abundance data ...
