Marine Ecological Journal| Резюме: | The information about the dominant species of macro- and meiobenthic polychaetes of the seaside estuary of Danube River has presented. According to the results of analysis of variance (ANOVA) it has established that the depth and type of substrate significantly influence on the total number of macrozoobenthic polychaete worms; the depth, sediment type and salinity form the total biomass. The highest abundance and biomass reported on muddy bottoms at the depths of 10.1 – 20 m, dominated by Neanthes succinea and Heteromastus filiformis; at the depths 20 m or more – Melinna palmata. Significant values of abundance were formed at the salinity of at least 10 ‰. The largest number of juvenile polychaetes (pseudomeiobenthos) were recorded in autumn, dominant species were N. succinea and Polydora cornuta. A feature of polychaete taxocene of seaside estuary was almost complete absence of the eumeiobenthos. |
