Figure 5.

Scatter plots of CCA between soil properties and nematode indicators (MI, maturity index; PPI, plant-parasitic index; BI, basal index; CI, channel index; EI, enrichment index; SI, structure index; Pp/B+F, the ratio of obligate plant parasites to bacterivores and fungivores). Siena, percentage of variance explained was 29.35% for axis 2 (p < 0.05), no significance for axis 1. Foggia, percentage of variance was 57.49% for axis 1 (p < 0.04) and 36.75% for axis 2 (p < 0.004). Ragusa, percentage of variance explained was 24.38% for axis 2 (p < 0.05), no significance for axis 1. Trapani, percentage of variance was 80.91% for axis 1 (p < 0.001) and 18.00% for axis 2 (p < 0.007).
