The relative concentrations of DIC species are influenced by symbiont photosynthesis and CO 2-uptake during the day ... Webthe presence of active photosynthesis in the foraminifera is given by the measurement of fluorescence induced by light capture in the photosystem II of the algal chloro-phyll. These methods have been used in benthic symbiont-bearing foraminifera (e.g., Uthicke, 2006; Schmidt et al., 2011; Ziegler and Uthicke, 2011) and have been recently suc-

WebForaminifera, or forams for short, are single-celled organisms that live in the open ocean, along the coasts and in estuaries. Most have shells for protection and either float in the water column (planktonic) or live on the sea floor (benthic). Of the approximately 8,000 species living today, only about 40 species are planktonic, thus the vast ...
