FIGURE 3 in New Miocene fossil taxa illuminate the evolution and paleobiogeography of the Ponto-Caspian gammaroid amphipod radiation

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.
