- Summary of results of three-way ANOVA considering species number (S), species abundance (N) and Hill’s diversity indices (N1 and N21) for factors sediment profile (effect of different sediment layers-three levels: 0–5 cm, 5–10 cm and 10–20 cm down through the sediment), station (spatial effect-three levels: station IP-10, IP-17 and IP-38) and sampling period (temporal effect-three levels: prior to trawling period, 30 and 120 days after intense bottom trawling period) (asterisk denotes statistically significant results).
