Figure 1. A. Location of new collection fromPorites spp. Included in this study. B. Bayesian
posterior consensus tree of Ostreobium spp. based on chloroplast
gene rbcL , with red labels indicating new sequence data resulting
from this study Numbers to the right of each branch represent the
posterior probability of the indicated clade. The two dotted lines refer
to possible closing date of the Isthmus of Panama according to Montes
et al. (2012) (older date, 12-15 Ma) and O’Dea et al. (2016) (the
younger date of 3 Ma). Localities are indicated by the four colors,
where green corresponds to samples from the Atlantic ocean, purple
indicates Pacific, red is the Red Sea, and samples highlighted in Yellow
are from the Indo-Pacific. The purple horizontal bars represent the 95%
Highest Posterior Density for the node divergence time.
