Size distributions of biotic assemblages are important modifiers of productivity and function in marine sediments. We investigated the distribution of proportional organic biomass among logarithmic size classes (2(-6)J to 2(16)J) in the soft-bottom macrofaunal communities of the Strait of Georgia, Salish Sea on the west coast of Canada. The study examines how size structure is influenced by 3 f...

Biological diversity examines to study the habitats of the earth and marine environment which has a greater extent covers the oceans and soft sediment habitats. It helps us to find the associated terrestrial systems, and knowledge of marine biodiversity. Habitats are holding an assorted arrangement of macrobenthic communities which plays important roles in ecosystem processes like reprocess the...

Samples of macrobenthic organisms were obtained at seven stations on a presumed pollution gradient from the head of Vancouver Harbour through to outer Howe Sound. Polychaetes (83 apparent species) and molluscs (43 apparent species) were the most abundant faunal groups numerically (44.8 and 47.9%, respectively). Molluscs accounted for most of the biomass (87.9%). The following univariate and mul...

The study of interannual changes in the structure soft soil macrobenthic communities was carried out on basis material collected three littoral sites waters Keret archipelago White Sea 1983– 2013. analyzed differed biotopic heterogeneity (characteristics soil, degree closure water areas, salinity regime). This is a sandy beach seaward zone, and two silt-sandy beaches semi-enclosed practically c...

A menippid crab Myomenippe hardwickii (Gray, 1831) was obtained in the macrobenthic collections from Hukitola, a mangrove-associated Bay located south of Bhitarkanika, Odisha, on east coast India. Although reported coastal waters adjoining Andhra Pradesh and West Bengal, documentation species Odisha remained elusive until current study. Therefore, diagnosis with suitable illustrations ecologica...

Faunal analysis of modern (Benguela upwelling system, Namibia) and ancient (upper Cretaceous, Israel) sedimentary records rich in organic matter, biogenic silica, carbonate, and phosphate indicates that, contrary to stereotypes of upwelling systems as dead zones, macrobenthic communities are present but highly variable. Biofacies vary with distance from the upwelling core and as a function of b...
