Biological effects of OCA

Shark feeding could be affected by changes in seawater chemistry projected for the end of this century. When smooth dogfish were placed for five days in ocean acidification conditions, [...]

A species of burrowing shrimp was able to tolerate ocean acidification conditions (pH 7.64) for 35 days. At a lower pH of 7.35, individuals experienced extracellular acidosis, [...]

Ocean acidification increased the rate at which sponges bored into scallop shells. At pH 7.8, sponges bored twice the number of papillar holes and removed two times more shell [...]

Common sunstar larvae and juveniles in ocean acidification conditions grew faster without apparent effects on survival or body structure. Unlike the larvae of some other sea [...]

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 [...]

The ongoing warming and acidification of the world’s oceans are expected to influence the marine ecosystems, including benthic marine resources. Ocean acidification may especially [...]

Humans are continuing to add vast amounts of carbon dioxide (CO2) to the atmosphere through fossil fuel burning and other activities. A large fraction of the CO2 is taken up by the oceans in a [...]

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 [...]

Blue mussels exposed to highly acidified seawater for sixty days were able to protect their body tissues involved in reproduction, digestion, and respiration. However, the physiological [...]

Juvenile oysters living in acidified seawater had higher mortality rates and less growth of shell and soft-body tissues. They also had higher metabolic rates, likely because of the higher energy [...]
