Figure 7
Partitioning of assimilated 13C and 15N in the coral symbiosis after 6 hours. Shown are the shares of the total cross-sectional area composed of symbiont (yellow), host gastrodermis (orange), and host epidermis (red) of the surface body wall coenenchyme and the 13C- and 15N distribution across these compartments in each mode of nutrition (pie charts left to right) at ambient conditions (outer filled part) and after 11.2 DHW (inner clear part). Data for C and N partitioning were obtained by combining the size of each compartment with its average 13C and 15N turnover (Fig. 6) obtained from multiple NanoSIMS images (N indicated; see also IAF calculation in Methods). These data provide a semi-quantitative view on the distribution of the assimilated C- and N-pool at the end of the 6 h pulse.
