...Jacob R. Winnikoff; Steven H. D. Haddock; Itay Budin ABSTRACT Animals are known to regulate the composition of their cell membranes to maintain key biophysical properties in response to changes in temperature. For deep-sea marine organisms, high hydrostatic pressure represents an additional, yet...

...Cornelia Maier; Pauline Popp; Nicole Sollfrank; Markus G. Weinbauer; Christian Wild; Jean-Pierre Gattuso ABSTRACT Ocean acidification is a major threat to calcifying marine organisms such as deep-sea cold-water corals (CWCs), but related knowledge is scarce. The aragonite saturation threshold (Ω...

...Malik S. Naumann; Covadonga Orejas; Christian Wild; Christine Ferrier-Pagès SUMMARY Scleractinian cold-water corals (CWC) represent key taxa controlling deep-sea reef ecosystem functioning by providing structurally complex habitats to a high associated biodiversity, and by fuelling biogeochemical...

...Brad A. Seibel; Patrick J. Walsh SUMMARY A recent proposal to store anthropogenic carbon dioxide in the deep ocean is assessed here with regard to the impacts on deep-living fauna. The stability of the deep-sea has allowed the evolution of species ill-equipped to withstand rapid environmental...
