Respective effects of sponge type, sponge taxonomy, geographic location and water depth on the structure of sponge-associated bacterial communities.

aSimple and partial RDA models were used to quantify the relative effects of sponge type (HMA versus LMA), sponge family, and sponge species, in combination with the co-factors reef location and water depth, on changes in bacterial community structure. The “|” sign indicates that the effects of the factors in parenthesis were accounted for by partial regression analysis.bDegrees of freedom.cCoefficient of determination (R2) of each multivariate model, adjusted for the number of explanatory terms in the respective model. Significances of the F ratios, as determined by 1000 Monte Carlo permutation tests, are indicated as ***, P
