Figure 4
δ13C in A. viridis from sites 1 (control), 2 (intermediate pCO2) and 3 (high pCO2).
(a) Mean δ13C (‰) values (±SEM; n = 5) of Symbiodinium (white circles) and animal tissue (black circles). (b) δ13CT vs. δ13CS (‰) for individual A. viridis specimens from sites 1 (triangles), 2 (squares) and 3 (circles). Note that the mean pCO2 (μatm; Table 1) is given in parentheses for each sampling site.
