Figure 2. A. Bayesian MCMC consensus tree of algae samples in the genus, Ostreobium , based on the chloroplast gene rbcLand species delimitation results, the names correspond whit host or source that inhabit the algae. Colored bars to the right of the phylogeny represent grouping based on GMYC and mPTP and the origin of the numbers represent the groups that coincide between the two analyses. Grey bars represent the sequences that are not grouping by the analysis. Red labels represent sequences obtaining in this study. Images of somePorites spp. Included in this study B. Porites furcata (Rosario islands, 3 m), C. P. porites (San Andrés, 22 m) D. Porites astreoides (San Andrés island, 5 m), E. P. furcata broken skeleton showing the greenOstreobium band, F. P. lobata (Gorgona island, 7 m),G. P. panamensis (Gorgona island, 10 m) (Photo credits: J.A. Sánchez).
