Thresholds of hypoxia for marine biodiversity.
Hypoxia is a mounting problem affecting the world's coastal waters, with severe consequences for marine life, including death and catastrophic changes. Hypoxia is forecast to increase owing to the combined effects of the continued spread of coastal eutrophication and global warming. A broad comparative analysis across a range of contrasting marine benthic organisms showed that hypoxia threshold...
متن کاملGeneration of Tetracosahexaenoic Acid in Benthic Marine Organisms.
Tetracosahexaenoic acid (THA, 24:6n-3) has been shown to have the strongest ability to suppress accumulation of lipids in HepG2 cells among well-known n-3 highly unsaturated fatty acids, such as EPA and DHA. In this study, a method for mass production of THA was investigated using distributions of THA and DHA in thirty-two marine organisms, such as starfishes, right-eyed flounders, shellfishes,...

متن کاملEffects of fluctuating hypoxia on benthic oxygen consumption in the Black Sea (Crimean Shelf)
The outer western Crimean shelf of the Black Sea is a natural laboratory to investigate effects of stable oxic versus varying hypoxic conditions on seafloor biogeochemical processes and benthic community structure. Bottom-water oxygen concentrations ranged from normoxic (175 μmol O2 L ) and hypoxic (< 63 μmol O2 L ) or even anoxic/sulfidic conditions within a few kilometers’ distance. Variation...
متن کاملImproved oxygen isotope temperature calibrations for cosmopolitan benthic foraminifera
Despite decades of use as a paleoceanographic proxy, considerable uncertainty still surrounds the temperature dependence of benthic foraminiferal dO. Widely applied paleotemperature equations may mix non-equilibrium foraminifera with equilibrium synthetic calcite, resulting in temperature sensitivities that are too large. Warm-water foraminiferal calibrations may give temperature sensitivities ...
