. Canonical correspondence analysis (CCA) ordination plot of plant-parasitic nematode abundances and soil properties. The length and angle of arrows indicates the relative
contribution of a particular soil property to the axes. To reduce clutter, only the eight most important soil properties (as determined by forward selection of models) are shown.
Nematode genera abbreviations are: Cri ¼ Criconemoides, Hel ¼ Helicotylenchus, Hem ¼ Hemicycliophora, Tri ¼ Trichodorus, Tyl ¼ Tylenchorhynchus, and Xip ¼ Xiphinema.
