Unifying the functional diversity in natural and cultivated soils using the overall body-mass distribution of nematodes

Table 1 Environmental-driven functional trends (Divergence, FD, Evenness, FE, Richness, FR, and overall body-mass distribution, BMD) for positive or negative Pearson’s correlation coefficients (upper lines, italics) and significances (n = 200, Prob > |r|, lower lines) for the body-mass distribution of nematodes and soil abiotics (pH, carbon, nitrogen and phosphorus)
