Seaweed and seagrasses

Ocean acidification is a pervasive stressor that could affect many marine organisms and cause profound ecological shifts. A variety of biological responses to ocean acidification have been [...]

Ocean acidification represents a threat to marine species worldwide, and forecasting the ecological impacts of acidification is a high priority for science, management, and policy. As [...]

Although seagrasses and marine macroalgae (macro-autotrophs) play critical ecological roles in reef, lagoon, coastal and open-water ecosystems, their response to ocean acidification (OA) and [...]

Rising atmospheric carbon dioxide (CO2), primarily from human fossil fuel combustion, reduces ocean pH and causes wholesale shifts in seawater carbonate chemistry. The process [...]

Ocean and coastal acidification is occurring due to uptake of atmopsheric CO2, as well as nutrient-fueled respiration in some estuarine and costal environments. Multiple stressors, [...]

Seaweeds are key species of the Baltic Sea benthic ecosystems. They are the substratum of numerous fouling epibionts like bryozoans and tubeworms. Several of these epibionts bear calcified [...]

Ocean acidification (pH 7.7) impaired growth and development of an intertidal barnacle (Semibalanus balanoides), but warmer temperature (+4 °C) did not. The mineral composition of the [...]

Seagrass ecosystems are expected to benefit from the global increase in CO 2 in the ocean because the photosynthetic rate of these plants may be Ci-limited at the current CO 2 level. As well, it [...]

Ocean acidification reduces the concentration of carbonate ions and increases those of bicarbonate ions in seawater compared with the present oceanic conditions. This altered composition of [...]

Studies in Italy and in the Chesapeake Bay, USA, found that seagrasses lost phenolics, which protect against grazing and disease, when living in high CO2/low pH conditions. The findings [...]
