Benthic Assemblage Composition of South Atlantic Seamounts

چکیده
Seamounts and oceanic islands rise from the seafloor provide suitable habitat for a diverse range of biological assemblages including Vulnerable Marine Ecosystems (VMEs). Whilst they have been focus some work globally, there has little description physical environments seamounts in South Atlantic Ocean. In this study, we characterized benthic assemblage composition 13 spanning 8–40°S within exclusive economic zones (EEZs) Ascension Island, Saint Helena Tristan da Cunha. Drop camera imagery was collected between 170 1000 m. All fauna present images were identified quantified, multivariate statistics used to describe identify their environmental drivers. Benthic communities temperate regions (Tristan Cunha archipelago) shown be distinct those found tropics, with latitude depth as key drivers composition. Our results are consistent current understanding biogeography Atlantic, both terms distinction tropical regions, influence water mass structure on distribution.

Extraordinarily high biomass benthic community on Southern Ocean seamounts
We describe a previously unknown assemblage of seamount-associated megabenthos that has by far the highest peak biomass reported in the deep-sea outside of vent communities. The assemblage was found at depths of 2-2.5 km on rocky geomorphic features off the southeast coast of Australia, in an area near the Sub-Antarctic Zone characterised by high rates of surface productivity and carbon export ...
متن کاملBetween-Habitat Variation of Benthic Cover, Reef Fish Assemblage and Feeding Pressure on the Benthos at the Only Atoll in South Atlantic: Rocas Atoll, NE Brazil
The Southwestern Atlantic harbors unique and relatively understudied reef systems, including the only atoll in South Atlantic: Rocas atoll. Located 230 km off the NE Brazilian coast, Rocas is formed by coralline red algae and vermetid mollusks, and is potentially one of the most "pristine" areas in Southwestern Atlantic. We provide the first comprehensive and integrative description of the fish...
متن کاملSpionidae (Polychaeta: Canalipalpata: Spionida) from seamounts in the NE Atlantic.
Spionidae (Polychaeta) collected from seamounts in the Atlantic Ocean were studied. Altogether six species were found of which two are new to science and one belongs to a new genus. Aonidella cf. dayi Maciolek in López-Jamar, 1989 and Glandulospio orestes gen. et sp. nov. were the most common species and occurred on both the Great and Little Meteor Seamount, the Irving Seamount and the Hyeres S...
