FIGURE 4 Morphological diversity of extant and fossil Ponto-Caspian gammaroids based on 43 morphometric measurements. (A) PCA plot depicting the morphospace occupation along the first two axes. Extant non-monotypic genera are shown with dimmed colors (dots or convex hulls if n> 2 species) while monotypic genera are shown with a gray square. Fossil taxa are shown with colored stars that are numbered according to species (see legend on lower left). Extreme morphologies are exemplified by drawings. (B) Biplot of variables along the first two PCA axes. C) A 3D PCA indicating morphospace occupation of fossils (colored triangles) and extant (gray dots) taxa within the first three axes.

FIGURE 3 Multivariate clustering (Ward's method) based on a Gower-transformed matrix of 114 morphological characters. The heat map represents a pairwise matrix of Euclidean distances among taxa. High similarity is shown with blue while low similarity with red. Green dots at nodes in the dendrograms indicate wellsupported groups (bootstrap values> 70%). The fossil clade is highlighted with orange and dagger symbol. Ecomorphs (sensu Copilaș-Ciocianu & Sidorov, 2022) are indicated with labels.

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).
