Biodiversity, community structural shifts, and biogeography of prokaryotes within Antarctic continental shelf sediment.
16S ribosomal DNA (rDNA) clone library analysis was conducted to assess prokaryotic diversity and community structural changes within a surficial sediment core obtained from an Antarctic continental shelf area (depth, 761 m) within the Mertz Glacier Polynya (MGP) region. Libraries were created from three separate horizons of the core (0- to 0.4-cm, 1.5- to 2.5-cm, and 20- to 21-cm depth positio...
متن کاملChanges of macrobenthos composition under different ENSO cycle conditions on the continental shelf off central Chile
The course of environmental conditions and shelf macrobenthic communities off Central Chile ( 361S) during the strong 1997–98 El Niño (EN) event is compared with a subsequent and basically ‘‘normal’’ period (2002–2003). Changes in macrofaunal community, feeding mode structure, and biomass size spectra are contrasted over time with changes in oceanographic and sediment settings, in order to asse...
متن کاملSediment Movement on the Continental Shelf near Washington and Oregon.
The nuclides zinc-65 and cobalt-60 associated with river-borne particulate matter are incorporated in sediment on the Continental Shelf near the Colum- ia River. Changes in the relative concentrations of zinc-65 and cobalt-60 and in the ratio of the activity of zinc-65 and cobalt-60 suggest that radioactive sediment moves northward 12 to 30 kilometers per year along the shelf and 2.5 to 10 kilo...

متن کاملA Study of Marine Biodiversity: Macrobenthos in Arabian Gulf
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...
