  1. Summary of results of two-way ANOVA considering species number (S), species abundance (N) and Hill’s diversity indices (N1 and N21) for factors sampling period (temporal effect-three levels: prior to trawling period, 30 and 120 days after intense bottom trawling period) and station (spatial effect-three levels: station IP-10, IP-17 and IP-38) (asterisk denotes statistically significant results).
