FIGURE 2 in New Miocene fossil taxa illuminate the evolution and paleobiogeography of the Ponto-Caspian gammaroid amphipod radiation

FIGURE 2 Phylogenetic relationships among Ponto-Caspian gammaroids based on 114 morphological characters. Non-monotypic genera are highlighted in color. The fossil clade is highlighted with orange and a dagger symbol. Number at nodes represent support values for maximum likelihood (UFBS – ultrafast bootstrap, SHaLRT – Shimodaira-Hasegawa approximate likelihood ratio test), Bayesian (PP – posterior probability), and parsimony (JKBS – jackknifing bootstrap) analyses. Strongly supported nodes are highlighted with a green dot (UFBS ≥ 90; SHaLRT ≥ 80; PP ≥ 0.9; JKBS ≥ 90). Nodes that are not annotated received weak to no support (UFBS ≤ 50; SHaLRT ≤ 50; PP ≤ 0.5; JKBS ≤ 50).
