The results indicate that the species abundances, biomass, and diversity in spring 2011 were all lower than those in autumn 2000 and spring of 2001. Most of the dominant species have changed from 2001 to 2011, with the exception of the echinoderm Ophiura sarsii vadicola that was dominant in these years. Small-sized animal species have increased possibly due to gradual environment deterioration such as the pollution and the climate warmer.展开更多
