Fig. 7

Ulvophyceae diversity. RAxML tree displaying 901 tufA sequences of the order Bryopsidales and ‘Ulvales-Ulothrichales’ based on an alignment of 891 bp. The tree was rooted with few outgroup taxa of the Chlorophyta and edited in iTOL for bootstrap support, molecular species, and sequencing method (Sanger, Cloning or Metabarcoding). OTU abundance color-coded for high read counts (red), moderate (brown) and low (black). Congruent clusters of molecular species between ABGD and GMYC are represented in alternating dark and light grey colors. Incongruent species boundaries are displayed in alternating colors yellow and red. Taxonomy is reported on the tree margin. Note important incongruence in molecular species delimitation between the two methods in the families Caulerpaceae and Halimedaceae
