Fig. 3. Grassland management impact on soil food web.

Principal coordinates analysis (PCoA) of soil food web communities from grasslands with different land management (extensive in orange, intensive in blue) from the control plots at 5 sampling date (n = 90). The PCoA was based on Bray–Curtis distance using soil mesofauna abundances (individuals m⁻²) and PLFA biomass (g m⁻²). Grey arrows show the correlation vectors of the variables with the ordination. Significance was tested by Monte Carlo permutation against 999 random datasets and variables with P > 0.05 were kept (see Supplementary Table 2).
