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.补充图1：基于DBSCAN密度聚类算法生成的可视化图谱，展示了如何利用1）后足腿节（hind femur，HF）、2）前足胫节（front tibia，FT）与3）头宽（head width，HW）这三项形态计量性状，预测某一物种的形态型数量。该图谱呈现出两个截然不同的聚类簇，对应黄翅大白蚁（Macrotermes gilvus）的两类个体：左侧红色簇为小型兵蚁，右侧绿色簇为大型兵蚁。以下为依次分析各近缘社会复杂性性状解释力所得的结果：功能不育（functional sterility，FS）、专性不育（obligate sterility，OS）、蚁群规模（colony size，CS）、蚁巢复杂度（nest complexity，NC）与帮手多型性（helper polyphenism，HM）。
