Ocean acidification conditions interfered with the chemoreception, or "smelling", that hermit crabs use to find shells and prey. The hermit crabs moved less, had lower flicking rates of their antennae (a ‘sniffing’ behavior in decapods), and were less successful in locating the odor source. (Laboratory study)
Hermit crabs living in highly acidified seawater (pH 6.8) were less likely to leave a suboptimal shell in favor of an optimal shell. Those that did change shells took longer to do so. Crabs in acidified water also moved less and had lower flicking rates of their antennae (a ‘sniffing’ ...
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.
Ocean acidification did not have a major impact at the cellular level in the gill epithelia of green crabs. (Laboratory study)
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)
