FIGURE 5.

Distance-based RDA of protist OTUs in soil of four land-use systems (rainforest, jungle rubber, rubber, and oil palm plantation). Factors in black and bold are significant in the forward selection procedure and are used as constraining factors (soil pH, canopy openness, plant abundance, soil fauna abundance, the sum of Gram-positive bacterial phospholipid fatty acids = GRAM+^PLFA), factors in gray are not significant (water content = H₂O, microbial basal respiration = Basal respiration, microbial biomass = C_mic, C concentration = C, N concentration = N, air temperature, humidity, plant richness, soil fauna richness, the sum of Gram-negative bacterial phospholipid fatty acids = GRAM-^PLFA, the sum of fungal phospholipid fatty acids = Fungi^PLFA and relative marker of arbuscular mycorrhizal fungal neutral lipid acid = AM-Fungi^NLFA). The position of trophic groups represents their centroid.
