FIG. 7 in Ulva L. biodiversity in the central Mediterranean Sea: cryptic species and new records

FIG. 7. — Consensus phylogenetic tree of Ulva L. species inferred from tufA sequences. Bayesian Inference (BI) and Maximum likelihood (ML) analysis were carried out for 44 specimens and one outgroup taxon. The numbers on branches are Bayesian posterior probabilities (BPP) and bootstrap (BS) values (> 0.7 and 70%, respectively). Asterisks indicate full support (= 1.00 and 100%). The scale bar represents the number of substitutions per site.
