Figure 1.
Ancestral state reconstruction of ant habitat.
Ancestral state reconstruction of ant habitat strata based on phylogram plus 500 trees sampled from the original likelihood distribution of Brady et al. [9]. The outgroup in this reconstruction performed in the program RASP was coded as soil-dwelling, surface-dwelling or arboreal. The root node of ants is reconstructed as being subterranean (soil dwelling) with a posterior probability of 91.45%.

Support for Leptanillinae as sister to all other ants.
Three depictions of a four-cluster likelihood map visualizing the strength of the phylogenetic signal supporting the placement of lepantillines outside the poneroid + formicoid clade. The top triangle indicates density of individual reconstructions; bottom left and right indicate percentage of points in divided cluster-space, with each tip representing a particular hypothesis (or specific arrangement of taxa). a: outgroups, b: leptanillines, c: poneroids, d: formicoids.

Figure 3.
Evolutionary transitions among habitat strata.
Rate of transitions among six habitat states summarized across 500 trees sampled from the original likelihood distribution of Brady et al. [9]. Thickness of arrows corresponds to rate of transitions. The percentages of ant genera that occupy a habitat category are indicated within each circle.
