Ocean acidification, which like global warming is an outcome of anthropogenic CO2emissions, severely impacts marine calcifying organisms, especially those living in coral reef ecosystems. However, knowledge about the responses of reef calcifiers to ocean acidification is quite limited, although coral responses are known to be generally negative. In a culture experiment with two algal symbiont-bearing, reef-dwelling foraminifers, Amphisorus kudakajimensis and Calcarina gaudichaudii, in seawater under five different pCO2 conditions, 245, 375, 588, 763 and 907 µatm, maintained with a precise pCO2-controlling technique, net calcification of A. kudakajimensis was reduced under higher pCO2, whereas calcification of C. gaudichaudii generally increased with increased pCO2. In another culture experiment conducted in seawater in which bicarbonate ion concentrations were varied under a constant carbonate ion concentration, calcification was not significantly different between treatments in Amphisorus hemprichii, a ... : Supplement to: Hikami, Mana; Ushie, Hiroyuki; Irie, Takahiro; Fujita, Kazuhiko; Kuroyanagi, Azumi; Sakai, Kazuhiko; Nojiri, Yukihiro; Suzuki, Atsushi; Kawahata, Hodaka (2011): Contrasting calcification responses to ocean acidification between two reef foraminifers harboring different algal symbionts.
