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：本图为DBSCAN聚类算法生成的可视化结果，展示了如何利用1）后足股节（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，预测某一物种的品级数目。图中存在两个界限清晰的聚类簇，对应黄翅大白蚁（Macrotermes gilvus）的两个类群：小型兵蚁（图左侧，红色）与大型兵蚁（图右侧，绿色）。以下为依次分析各近因社会复杂性性状解释力所得的结果：功能型不育（functional sterility, FS）、专性不育（obligate sterility, OS）、巢群规模（colony size, CS）、巢穴复杂度（nest complexity, NC）以及辅助者多型性（helper polyphenism, HM）。
