Additional file 1 of Host starvation and in hospite degradation of algal symbionts shape the heat stress response of the Cassiopea-Symbiodiniaceae symbiosis

Additional file 1: Figure S1. Schematic presentation of the experimental setup viewed from the side and from above with sampling design information. Figure S2. Photos of the medusae collected at SP2 on day 1 and 10 of the experiment in the control treatment, and heat stress treatment. Figure S3. Impact of heat stress on chlorophyll a content and algal symbiont density per wet weight. Figure S4. Temperature effects on the enrichment from assimilation of isotopically labeled bicarbonate and ammonium in the epidermis of heat-stressed medusae. Figure S5. SEM and 12C2- and 14N12C- NanoSIMS images corresponding to the correlative SEM and NanoSIMS images presented in Fig. 3. Figure S6. Tissue and cellular ultrastructure of control and heat-stressed medusae bells at SP2 imaged by light microscopy with H&E staining and SEM. Table S1. Number of NanoSIMS images per biological replicate and the associated number of regions of interest (ROIs) per Cassiopea compartment defined for the isotopic enrichment analyses.
