Defensive advantage of colonies in the asexual lineage. a Cross section showing the structure of a Glyptotermes nakajimai nest. Small tunnels connecting chambers are indicated by arrows. (inset, right) A tunnel-blocking soldier (phragmotic defense). Scale bars, 2 mm. b Comparison of the within-colony coefficient of variation (CV) of soldier head width between the asexual and sexual lineages. Values are mean ± SEM (n = 5). Individual data points are represented by open circles. *, P < 0.05 (Mann–Whitney U test). For raw data, see Additional file 7c Comparison of the proportion of soldiers to other individuals of mature field colonies between the asexual and sexual lineages. Values are mean ± SEM (n = 37). Individual data points are represented by open circles. ****, P < 0.0001 (GLM). For raw data, see Additional file 7
