Table 2. Results of the one-way ANOSIM (global and pairwise tests) for the MDS performed with all samples collected.

Differences between samples collected during periods of intense upwelling (IU), weak upwelling (WU) and downwelling (D) were assessed. The statistic estimated for each permutation is significant when its value is greater than or equal to the sample statistic. Significance level is calculated as the percentage of significant statistics in the total number of permutations used. R: Sample statistic.

	R	Statistic significance	Number of permutations	Significant statistics
Global test:
Upwelling	0.061	1.8% *	9999	180
Pairwise tests:
WU-IU	0.080	4.7% *	9999	468
WU-D	0.040	9.5% ns	9999	952
IU-D	0.103	0.3% **	9999	31

*: significant;

**: very significant, ns: non significant values.
