Carbon processing by the benthic ecosystem and benthic C fixation in methane-rich sediments on the South Georgia margin KU Leuven
© Copyright Antarctic Science Ltd 2019. As bottom water warms, destabilisation of gas hydrates may increase the extent of methane-rich sediments. The authors present an assessment of organic carbon processing by the benthic community in methane-rich sediments, including one of the first investigations of inorganic C fixation in a non-hydrothermal vent setting. This topic was previously poorly studied, and there is much need to fill the gaps in ...
Evaluating the consequences of bottom trawling on benthic pelagic coupling and ecosystem functioning Universiteit Gent
Do habitat type and dredge disposal intensity determine sensitivity of the marine benthic ecosystem? Instituut voor Landbouw-, Visserij- en Voedingsonderzoek
Multiple human activities are executed in the Belgian part of the North Sea (BPNS), such as sand extraction, fisheries, offshore wind energy installations and dredging of navigation channels, with the associated disposal of dredged material at sea. We assessed the impact of the dredge disposal activities on the benthic ecosystem, i.e. organisms living in, on and near the bottom, to evaluate the sensitivity of different habitat types and ...
Interregional comparison of benthic ecosystem functioning: Community bioturbation potential in four regions along the NE Atlantic shelf Instituut voor Landbouw-, Visserij- en Voedingsonderzoek Universiteit Gent
Bioturbation is one of the key mediators of biogeochemical processes in benthic habitats that can have a high contribution to seafloor functioning and benthic pelagic coupling in coastal waters. Previous studies on bioturbation were limited to point locations and extrapolations in single regions, but have not accounted for regional differences under changing environmental conditions, though there are indications that species contributions will ...
Can pulse trawling reduce the mechanical impact on the benthic ecosystem in the bottom trawl fishery for sole? Instituut voor Landbouw-, Visserij- en Voedingsonderzoek
In the beam trawl fishery for sole in the North Sea, the twin beam trawl has dominated the fishery since the 1960s. Beam trawlers used heavy gear with tickler chains to chase sole out of the sea bed. The fishery is criticised for the mortality imposed on benthic invertebrates, the adverse effects on the sediment structure and on the high energy consumption. Since 2010, a number of vessels has switched to the economic more profitable pulse ...
Understanding the impact of sand extraction on benthic ecosystem functioning : a combination of functional indices and biological trait analysis Universiteit Gent
Marine aggregates have been intensively extracted in the North-East Atlantic over the past decades. This study aimed to assess the effect of sand extraction on benthic ecosystem functioning using a combination of biological traits and functional indices (the bioturbation (BPc) and irrigation potential (IPc) and secondary production (SPc) of the macrobenthic community). Data on macrobenthos, sediment properties and extraction intensity were ...
Impacts of diffuse urban stressors on stream benthic communities and ecosystem functioning Universiteit Antwerpen
Catchment urbanisation results in urban streams being exposed to a multitude of stressors. Notably, stressors originating from diffuse sources have received less attention than stressors originating from point sources. Here, advances related to diffuse urban stressors and their consequences for stream benthic communities are summarised by reviewing 92 articles. Based on the search criteria, the number of articles dealing with diffuse urban ...
