Distance-based redundancy analysis (dbRDA) plot of Distance-based linear modeling (DistLM) results in 2-dimensional space for environmental variables and macroinvertebrate community in dry and wet seasons. The length and direction of the vectors represent the strength and direction of the relationship (Alkal., alkalinity; Col., water color; Cond., electrical conductivity; Hard., hardness; Oxy., oxydability; Turb., turbidity).
