Free-living soil nematode genera recovered at the field site.

*Ba, bacterivore; Fu, fungivore; Ca, carnivore; Om, omnivore.These genera contributed >90% of individual non-parasitic nematodes at the site. The functional guild and their position on the coloniser-persister scale (1–5, shown as a suffix) are as previously assigned to each genus [22], [23]. The sequence identity of the amplified region of 18S small subunit ribosomal RNA gene to that of the most similar genus in the GenBank data set is indicated together with the Accession Number of the most similar database sequence.
