Benthic macroinvertebrates have many important ecological functions, such as regulating the flow of materials and energy in river ecosystems through their food web linkages. Because of this correlation between flow of energy and nutrients, benthic macroinvertebrates have the ability to influence food resources on fish and other organisms in aquatic ecosystems.

Methodology/Principal Findings. The synthesis of million bacterial V6-rRNA amplicons for samples that span the global ocean's surface to the deep-sea floor shows that pelagic and benthic communities greatly differ, at all taxonomic levels, and share Cited by: The Caldera of Axial Volcano‑‑Remote Sensing and Submersible Studies of a Hydro thermally Active Submarine Volcano, In: Global Venting, Midwater, and Benthic Ecological Processes, M. de Luca and I.

Trawling can be divided into bottom trawling and midwater trawling, depending on how high the trawl (net) is in the water trawling is towing the trawl along (benthic trawling) or close to (demersal trawling) the sea floor. Midwater trawling is towing the trawl through free water above the bottom of the ocean or benthic zone. Depending on the local situation and the ecological objectives, the bypass systems can be established by connecting existing floodplain water bodies or by constructing new artificial channels. The flow of the bypass system should mimic pre-damming flow hydrographs to enable dynamic hydromorphological processes (Fig. ).Cited by: 7.

Active liquid and gas venting at shallow depths may be occurring now elsewhere on the Oregon shelf. If this is the case, venting could have additional effects on the structure and functioning of benthic assemblages at the shelf edge by the introduction of methane.
The ecological roles of small ( mg) predators in benthic marine systems are poorly understood. We investigated the natural history and predatory impact of one group of such mesopredators.

Midwater trawling is also known as pelagic trawling. Midwater trawling catches pelagic fish such as anchovies, shrimp, tuna and mackerel, whereas bottom trawling targets both bottom-living fish (groundfish) and semi-pelagic fish such as.
