Fig. 5 in Phylogeny, evolution, and classification of the ant genus Lasius, the tribe Lasiini and the subfamily Formicinae (Hymenoptera: Formicidae)

Fig. 5. Results of the BioGeoBEARS and life-history trait ancestral state estimation analyses on a chronogram pruned from the analysis of the Lasiini_w_outgroups_w_fossils_154t combined morphological and molecular dataset. Horizontal blue bars at nodes are 95% highest posterior density (HPD) intervals from the divergence dating. Coloured circles on nodes are inferred inherited biogeographic ranges, with the top half of each corresponding to the upper branch and bottom half with the lower branch; coloured circles at branch tips represent biogeographical coding for terminal; dashed lines at 60 and 30 Ma indicate the boundaries of the three BioGeoBEARS dispersal rate matrix time periods. Coloured boxes at branch tips represent presence or absence of two traits for Lasius: temporary social parasitism (black = absence, red = presence) and fungiculture (black = absence, green = presence). Stars on internal branches indicate the evolution of temporary social parasitism (red) and fungiculture (green) The figure background indicates generalized major climatological regimes during Earth's history (Royer et al., 2004; Zachos et al., 2008; Hansen et al., 2013), while the inset globes visually represent palaeoclimate and landmass configuration modified from Scotese (1998).
