Field development of Posidonia oceanica seedlings changes under predicted acidification conditions
11 pages, 7 figures, 2 tables Ocean acidification has been consistently evidenced to have profound and lasting impacts on marine species. Observations have shown seagrasses to be highly susceptible to future increased pCO2 conditions, but the responses of early life stages as seedlings are poorly un...
