A coralline red alga that lives in tide pools, where it is common for CO2 levels to fluctuate tremendously daily and seasonally, was relatively robust to ocean acidification conditions, compared to other types of coralline algae. (Laboratory study)
While ocean acidification may have some negative effects on the eggs of amphipods, exposure to low-salinity water is likely to affect the eggs more, based on ocean acidification trends projected for the next 300 years. (Laboratory study)
In the gulf toadfish, respiratory gas transport and acid–base balance are affected by ocean acidification. While the full physiological impacts are not known, the changes could compromise several physiological systems. (Laboratory study)
This field study in Papua New Guinea examined the effects of natural carbon dioxide seeps on coral reef ecosystems. At reduced pH, coral diversity was lower, population replenishment and abundance of some corals decreased, and interactions among species changed. Reef development ceased below pH 7.7. Ocean acidification, together with warmer ...
Ocean acidification may favor growth of algal turfs rather than kelp forests. Such a change would affect the many species associated with algal turf or kelp forest habitats.
When Atlantic herring eggs were fertilized, incubated, and hatched in ocean acidification conditions, there was no effect on embryo development or hatch rate. There was also no clear relationship between ocean acidification and length, weight, yolk sac area, or otolith area of the newly hatched larvae. However, the larvae did ...
In ocean acidification conditions (pH 7.7) embryos of an intertidal barnacle developed more slowly. Survival of adult barnacles dropped by 22 percent, and the mineral structure of adult shells changed. (Laboratory study)
Ocean acidification did not have a major impact at the cellular level in the gill epithelia of green crabs. (Laboratory study)
Post-larvae of an intertidal barnacle (Elminius modestus) grew more slowly under ocean acidification conditions, but there were no impacts on its shell calcium content and survival by either ocean acidification or warmer temperature. were observed in high CO2 but there were no impacts on shell calcium content and survival by ...
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 shells did not change with either ocean acidification or warmer temperature. The combination of reduced growth and maintained mineral content suggests that the barnacles ...
