Fig. 2. Floridoside levels of Symbiodinium in vitro and in hospite at different salinities.

Fig. 2

Floridoside levels represent measured amounts (in nanomoles) per 105 cells ml−1 for cultured Symbiodinium and per dry weight (in milligrams) of isolated Symbiodinium for coral samples. Data obtained for each experiment were normalized to the highest value (set to 100%). (A) Floridoside levels in four cultured Symbiodinium strains in vitro at low (25), ambient (38), and high salinities (55). Smic, S. microadriaticum (type A1); Sym A1, Symbiodinium sp. type A1; Smin, S. minutum (type B1); Spsy, S. psygmophilum (type B2). (B) Floridoside levels for S. thermophilum isolated from P. lobata cultured at salinities of 34 and 42. (C) Floridoside levels of Symbiodinium from corals with a different long-term survival capacity at high salinities after incubation at a salinity of 42. Floridoside levels were determined for Symbiodinium sp. type C96 (P. lichen), S. thermophilum (P. lobata), and Symbiodinium sp. type C40 (Hydnophora grandis). Error bars denote SE. Letters indicate Tukey’s HSD (honestly significant different) post hoc test differences based on pairwise comparisons of analysis of variance (ANOVA) results [groups with different letters are significantly different at P < 0.01 for (A) and P < 0.05 for (C)]. Osmolyte levels represent measured amounts (in nanomoles) per 105 cells ml-1.
