Distribution of benthic diatoms in the littoral zone of the Gulf of Riga, the Baltic Sea [PDF]
European Journal of Phycology, 2000 The composition (% relative abundance) of the benthic diatom community was studied in the littoral zone (0–5 m) of the NW and E coasts of the brackish, non-tidal Gulf of Riga, in the Baltic Sea. The samples were collected concomitantly with measurements of sediment primary productivity and chlorophyll a during three cruises, representing three seasons (

Benthic phosphorus cycling in the Peruvian oxygen minimum zone [PDF]
Biogeosciences, 2016 Oxygen minimum zones (OMZs) that impinge on continental margins favor the release of phosphorus (P) from the sediments to the water column, enhancing primary productivity and the maintenance or expansion of low-oxygen waters.

Implications of a zoned fishery management system for marine benthic communities [PDF]
Journal of Applied Ecology, 2004 Summary The impacts of trawls and dredges on marine benthic habitats and communities have been studied extensively, but mostly at small scales and over short time periods. To investigate the large‐scale chronic impacts of towed fishing gears, zoned commercial fishery management systems allow comparison of habitats and communities between areas of ...

Benthic iron and phosphorus fluxes across the Peruvian oxygen minimum zone [PDF]
Limnology and Oceanography, 2012 Benthic fluxes of dissolved ferrous iron (Fe2+) and phosphate (TPO4) were quantified by in situ benthic chamber incubations and pore‐water profiles along a depth transect (11°S, 80‐1000 m) across the Peruvian oxygen minimum zone (OMZ). Bottom‐water O2 levels were < 2 µmol L−1 down to 500‐m water depth, and increased to ∼ 40 µmol L−1 at 1000 m.

Benthic nitrogen cycling traversing the Peruvian oxygen minimum zone [PDF]
Geochimica et Cosmochimica Acta, 2011 Benthic nitrogen (N) cycling was investigated at six stations along a transect traversing the Peruvian oxygen minimum zone (OMZ) at 11 °S. An extensive dataset including porewater concentration profiles and in situ benthic fluxes of nitrate (NO3–), nitrite (NO2–) and ammonium (NH4+) was used to constrain a 1–D reaction–transport model designed to ...

Acta Limnologica Brasiliensia, 2021 : Aim The maintenance and condition of riparian vegetation are important factors for conserving headwater streams and their species diversity. Thus, variations in the width of a riparian zone can have dramatic effects in the structure and functioning of

Journal of Limnology, 2022 The consistent warming of tropical lakes at all depths causes rapid development and long persistence of seasonal hypoxia in the hypolimnion, which greatly reduces the biodiversity of hypolimnetic benthic invertebrates. Full mixing of the water column in

Amazing Discoveries of Benthic Fauna from the Abyssal Zone of Lake Baikal [PDF]
Biology, 2021 Lake Baikal is a natural laboratory for the study of species diversity and evolution, as a unique freshwater ecosystem meeting the all of the main criteria of the World Heritage Convention. However, despite many years of research, the true biodiversity of the lake is clearly insufficiently studied, especially that of deep-water benthic sessile ...

The role of benthic foraminifera in the benthic nitrogen cycle of the Peruvian oxygen minimum zone [PDF]
Biogeosciences, 2012 Abstract. The discovery that foraminifera are able to use nitrate instead of oxygen as energy source for their metabolism has challenged our understanding of nitrogen cycling in the ocean. It was evident before that only prokaryotes and fungi are able to denitrify.

Benthic megafauna of the western Clarion-Clipperton Zone, Pacific Ocean
ZooKeys, 2022 There is a growing interest in the exploitation of deep-sea mineral deposits, particularly on the abyssal seafloor of the central Pacific Clarion-Clipperton Zone (CCZ), which is rich in polymetallic nodules. In order to effectively manage potential exploitation activities, a thorough understanding of the biodiversity, community structure, species ...
