Results of RDA permutation analyses on bacterial community data derived from ARISA, testing for the effects of membrane type (PE, PSF, and PVDF), treatment (adhesion, Ringer, biofilm), and the interaction between both factors. λ 1 and λ 2 represent the eigenvalues of the first and second axes. λ tot represents the percentage of total community variation explained by the experimental factors.
