... and diversity of benthos. The highest mean (± standard error) benthic density was 15113.4 ± 3885.3 m −2 at stations 53, which was significantly different from that of all the other stations (73.5 ± 16.8 to 1625.8 ± 275.4 m −2 ). Oligochaeta species, which are indicators of organic pollution, dominated...
