Photographs of free-living Symbiodinium habitats and individuals.
A. Photographs of Symbiodinium sp.-cell like sampled directly form macroalgal beds (Tobago samples). B–D. Bed-forming macroalgae samples where free-living zooxanthellae were sampled. B. Lobophora variegata. C. Halimeda spp. D. Amphiroa tribulus. (B–D. Salmedina Banks, 15 m, Cartagena, Colombia).
Table 1.
Summary of the sampling scheme. Reefs (sites), depths and number of samples (environmental and Sparisoma viride) collected.
Table 2.
Summary of the free-living Symbiodinium spp. clades found in the sampled reefs, depths, and substrates.
Figure 2.
Unrooted star phylograms of Symbiodinium spp.
Topologies were obtained with Bayesian inference (support for major clades are Bayesian clade credibility/maximum likelihood 100 bootstrap replicates). A. ITS2 phylogenetic hypothesis. B. cp 23S phylogenetic hypothesis. Terminal branch names correspond to the zooxanthellae clade letter plus GenBank accession numbers except for new free-living sequences.
