Constrained analysis of principal coordinates (CAP) of a bacterial and b fungal communities on decomposing roots maximizing discrimination between irrigation treatment and the different stages of decomposition. Different symbols indicate different stages of decomposition (time), whereas the color-coding refers to the communities in irrigated (blue) and control (orange) plots. Gray vectors show the correlation between the measured environmental variables (soil water content, remaining weight, Ad/AlV, Ad/AlS, δ13C, δ15N, C/N) and the ordinations scores, with the length of the vector corresponding to the correlation coefficient (r). Statistical significance of the squared correlation coefficient (r2) and the level of significance (P-value) of the environmental variable fit are provided in a legend table
