Effects of contextual parameters on variation in the wetland mat bacterial community structure.

Total and pure effects (i.e. when controlling for all other factors of the analysis) of explanatory factors were calculated by using canonical redundancy analysis (RDA) models. The proportion of explained community variation is expressed as R2 values. Significances of the respective F-ratios were tested by performing 1000 Monte Carlo permutation tests and are indicated by • marginally significant (P≤0.1), * significant (P≤0.05), ** very significant (P≤0.01), *** highly significant (P≤0.001), and ns when not significant (P>0.05).Effects of contextual parameters on variation in the wetland mat bacterial community structure.
