Photosynthetic characteristics of Symbiodinium in four Caribbean gorgonian species.

Sample sizes for each gorgonian species (see Figure 1 legend for full genus names) are given in parentheses next to the species name. Parameters include the abundant Symbiodinium (Sym) internal transcribed spacer region two (Sym ITS2) type, Sym cell density, chlorophyll content (chl), estimated absorbance at 675 nm (De 675), as well as the pressure over photosystem II (Qm). Table cells contain the sample mean ± standard deviation. The mean square (MS), F statistics (F), and significance value (p) from a one-way ANOVA, using gorgonian species as a factor, are shown for each variable. All variables were transformed prior to conducting the ANOVA. Means with different superscript letters were statistically different (α = 0.05) and this was diagnosed by Tukey's HSD post hoc tests. Power (1- β) is shown for non-significant results.Photosynthetic characteristics of Symbiodinium in four Caribbean gorgonian species.
