The dissimilarity of several functional composition between upper (blue), lower (green) and upper vs. lower (yellow) layer soil samples from two major TP ecosystems farmlands (left three boxes) and alpine meadow (right three boxes). Components of the box are: top of the box, upper hinge; midline of box, median; bottom of box, lower hinge; bars, 1.5 times length of box (1.5 times the horizontal spread); dots, values that are > or <1.5 times the horizontal spread of the distribution, plus the upper or lower hinge. The variation of dissimilarity was compared between farmland and alpine meadow ecosystems computed with Bray-Curtis based on relative abundance of functional genes in the KEGG pathway.
