FIGURE 2 in Needle in a haystack-genetic evidence confirms the expansion of the alien echinoid Diadema setosum (Echinoidea: Diadematidae) to the Mediterranean coast of Israel
FIGURE 2 Phylogenetic relationships of the genus Diadema. Superimposed Maximum Likelihood and Bayesian Inference phylogenetic trees based on COI sequences representing all extant species of Diadema, rooted by Astropyga radiata. Major clades were collapsed. The clades including Mediterranean Diadema sequences are highlighted in yellow (D. setosum clade b). Supporting values (> 0.9 posterior probabilities and> 70% ML bootstrap values) are shown above the nodes (before and after the slash, respectively). ML bootstrap support was calculated from 1000 replications and BI posterior probabilities from 7.5 million generations (after burn-in). GenBank accession numbers of the corresponding sequences used in the analysis are given in Supplementary materials Tab. S2.
