Table 3 Strength of association (r2) between environmental variables and NMS ordination axes for ordinations based on (a) arthropod feeding guilds, or (b) individual arthropod species. Environmental variables significantly correlated with each axis (P<0.05 after sequential Bonferroni analysis) are noted in bold.
