S1;Supplementary Results from The diversity of social complexity in termites

Supplementary Figure 1: A plot from DBscan showing how the morphometric traits of 1) hind femur (HF) 2) front tibia (FT) 3) head width (HW) are utilised to predict the number of morphs in a species. This shows two distinct clusters signifying Macrotermes gilvus; small soldiers (left of plots, red) and large soldiers (right of plots, green);The following are the results from analysing the explanatory power of each proximate social complexity trait in turn. FS, functional sterility; OS, obligate sterility; CS, colony size; NC, nest complexity; HM, helper polyphenism.
