Summary of results of two-way PERMONAVA with respect to the temporal (three levels: prior to trawling period, 30 and 120 days after intense bottom trawling period) and spatial (three levels: station IP-10, IP-17 and IP-38) variation components of benthic community structure (asterisk denotes statistically significant results).
