Fig. 2

Phylogenetic inference of 26 morphospecies of foraminifera using the COI (A) and SSU (B) barcodes based on 1000 transfer bootstrap. The colored rectangles indicate the three main clades of planktonic foraminifera: Microperforates (light-blue), Non-spinose (blue) and Spinose (purple). The branch support is indicated by the colored circles on the branches (only above 80%). Note that the COI and SSU trees have different scales (nucleotide substitutions per site) at a ratio of about 1:100. (C) Box-plot and jitter-plots showing the ratio in patristic distances (leaf to leaf distance) measured on the trees between the tree clades (Inter-clades), the genus within the clades (Inter-Genus) and the species within the same genus (Inter-Species). The pairwise t-test results, are shown above the plots.
