Different responses of functional traits and diversity of stream macroinvertebrates to environmental and spatial factors in the Xishuangbanna watershed of the upper Mekong River Basin, China

Variance partitioning analysis results of eight functional traits (Refuge (t1), Exoskeleton or external protection (t2), Respiration (t3), Body size (t4), Body shape (t5), Rheophily (t6), Habit (t7), Functional feeding groups (t8)) and six functional and trait diversity (FRic, FDis, RaoQ, TR, FEve, and TD) explained by spatial and environmental variables. The level of significance is given next to the bars. (* significance at α = 0.05, ** significance at α = 0.01).231
