Ancestral states reconstructions of genome size (Left) and TE abundance (Right) across 33 Synalpheus species. Branch colors indicate reconstructed values according to the scale bars below each phylogeny. Names and values on nodes represent the names and ancestral values of the ancestors of the four major Synalpheus clades, those with pair-living and eusocial species (the paraneptunus and rathbunae clades), with pair-living and communal breeding species (longicarpus clade), and with pair-living, communal breeding, and eusocial species (brooksi clade).
