The Greenland–Scotland Ridge in a Changing Ocean: Time to Act?
ABSTRACT The Greenland–Scotland Ridge is a submarine mountain that rises up to 500 m below the sea surface and extends from the east coast of Greenland to the continental shelf of Iceland and across the Faroe Islands to Scotland. The ridge not only separates deeper ocean basins on either side, that is, the North Atlantic and Arctic oceans, but also ...

Trawling is known to disturb benthic communities and habitats, which may in turn indirectly affect populations of commercial species that live in close association with the seabed.

SUMMARY Kelp forests are threatened by rising ocean temperatures. However, the effects of warming on early life stage interactions among co‐occurring kelp species, particularly competitive dynamics and reproductive timing, remain poorly understood. This study investigates the effects of temperature on embryonic sporophyte competitive interactions and ...

Secondary production (zooplankton and benthos)
In order to understand the dynamics of an ecosystem, it is necessary to determine the contribution of the different groups to total biomass as well as to evaluate their turnover rates and the amount of organic matter that each produces per unit time.

Abstract Introduction Coral reef restoration strategies are rapidly evolving to restore corals and reef functions in response to accelerating disturbances worldwide. One active restoration technique that is rapidly gaining momentum is the larval enhancement method which involves the introduction of cultured coral larvae directly onto degraded reefs ...

Feasibility of restoring native oyster reefs in highly modified urban estuaries
Abstract Introduction Urbanized estuaries are highly altered systems characterized by modified shorelines, degraded marine habitats, and abundant non‐native species. In South Australia's largest urbanized estuary, community‐based restoration initiatives aim to restore native flat oyster reefs (Ostrea angasi) lost over a century ago.

Specialized Committees of International Organizations an Important Source of Organizational Autonomy
ABSTRACT Assigning the preparation of decisions to specialized committees composed of member state representatives is a widespread response to the ‘governor's dilemma’, that is, the tension between competence and control, in international organizations (IOs). We theorize a causal mechanism referring to self‐selection and agenda‐setting effects and show

Benthic meiofauna in the Barents Sea were investigated for spatiotemporal variability and taxonomic composition. ABSTRACT Meiobenthic metazoans occur worldwide and are a cornerstone of aquatic ecosystems. Here, we investigate the composition of meiobenthic communities along a transect in the Barents Sea and Nansen Basin and provide the first ...

Primary Productivity and Habitat Depth Shape Developmental Mode in European Marine Gastropods
Thorson's rule suggests that marine gastropods in colder, high‐latitude regions tend to have non‐pelagic (non‐drifting) larval development. However, this study on 94 European gastropod species found that the rule disappears when examined at finer spatial scales, with temperature and phylogeny having little influence.

Temperate mesophotic ecosystems (TMEs) have the potential to act as climate refugia for shallower benthic species impacted by environmental change. However, the extent to which mesophotic ecosystems might provide an ecological refuge, particularly for key functional groups like sponges, remains poorly known in temperate systems.
