Mantel tests with 1000 permutations were performed on the
distance matrices of the plant parameters (Euclidean distance),
CLPP carbon use data (Euclidean distance), bacterial ARISA fingerprints
(BrayeCurtis distance) and fungal ARISA fingerprints
(BrayeCurtis distance), with the data of all harvesting points. The
bacterial and fungal fingerprints had a significant correlation coefficient
(r) of 0.31 (p < 0.05; H0: r 0), but these two datasets
differed strongly in their respective correlations with the plant and
CLPP data. Namely, while the bacterial fingerprints data had rvalues
of 0.2 (p < 0.05; H0: r 0) and 0.13 (p < 0.1; H0: r 0) with
the CLPP and plant data, respectively, the respective values for the
fungal fingerprint data were the non-significant 0.06 and 0.02
(p > 0.2; H0: r 0)
