Figure 3. Biogeographic and ancestral analyses. A.Inference of the historical biogeography of Ostreobium spp. using
Bayesian binary MCMC analysis (BBM) in RASP v. 3.0. Colors of pie wedges
at each node represent geographical areas inferred to have been occupied
by ancestral taxa. B. Mesquite Parsimony ancestral state
mapping suggesting the host for ancestors of Ostreobium spp.
Samples. The color of the branches represents the genera of the
ancestral host, some branches have two colors that represent the
uncertainly about the inferred host. The red labels in both cases
represent the new sequences of this study.
