Fig. 2

Scatter plots of the RDA residuals of Scottnema, Plectus, and Eudorylaimus. Residuals were obtained from an RDA model, the predictors of which were the same biotic and abiotic factors listed in Tables 1 and 2. RDA was applied to Hellinger transformed abundance data. Negative correlation is clear for the pairs Scottnema–Plectus (Pearson’s r = −0.59, P < 0.001) and the pairs Scottnema–Eudorylaimus (Pearson’s r = −0.60, P < 0.001)
