“…Increased CO 2 enhanced rates of primary productivity (Wu et al, 2010;Trimborn et al, 2013) and growth (Sobrino et al, 2008;Tew et al, 2014;Baragi et al, 2015;Chen et al, 2015;King et al, 2015) in some diatom species, while others were unaffected (Chen and Durbin, 1994;Sobrino et al, 2008;Berge et al, 2010;Trimborn et al, 2013;Chen et al, 2015;Hoppe et al, 2015;King et al, 2015;Bi et al, 2017). In contrast, CO 2 -related declines in primary productivity and growth rate have also been observed (Barcelos e Ramos et al, 2014;Hoppe et al, 2015;King et al, 2015;Shi et al, 2017), suggesting that responses to ocean acidification are largely species specific.…”
