(Normal seawater conditions in the locations where Carrington conducted her research are less acidic, with pH levels of 7.8, she said.) (aaas.org)
The researchers received another surprise when they used recently developed genomic approaches to compare the expression of genes related to calcification in coccolithophores grown under current and future seawater conditions. (sciencedaily.com)
The authors found that the oxygen consumption of Acropora digitifera larvae tended to be suppressed with reduced pH. Results also showed that the metamorphosis rate significantly decreased under acidified seawater conditions after both short (2 h) and long (7 d) term exposure. (reefresilience.org)
