Table 2 Spearman correlation of the first DCA axis with BIAS, structural properties of plots (number of species, cover of layers and bare rock) and bioindicator values. We used a permutation test, with which we treated bioindicator values
Variable | Axis 1 | p | Bioindicator | Axis 1 | P.par | P.perm | P.modif |
|---|---|---|---|---|---|---|---|
BIAS2 | 0.815 | *** | Light | 0.601 | *** | ** | - |
Number of species | − 0.325 | * | Temperature | 0.629 | *** | ** | * |
Cover tree layer | − 0.166 | - | Moisture | − 0.48 | *** | ** | - |
Cover tree layer burned | 0.835 | *** | Reaction | − 0.088 | - | - | - |
Cover bare rock | − 0.135 | - | Nutrients | 0.089 | - | - | - |
Cover shrub layer burned | 0.09 | - | |||||
Cover herb layer | − 0.809 | *** | |||||
Cover bare rock | 0.636 | *** | |||||
P, calculated probability in interval; ***0.001; **0.01; *0.05, as P.par, P parametric; P.perm., permutation test; P.modif, modified permutation test | |||||||
