| Abstract: | The present study investigated the macrobenthic community in Tolo Harbour, Hong Kong, aiming at linking heavy metal concentrations
to differences in macrobenthic community. The stations investigated in Tolo Harbour have widely contrasting features, with
some areas located in the Plove Cove displaying both high species richness and abundance while other areas displaying quite
impoverished or even void of macrobenthos. High diversity and abundance of macrobenthos in areas with low heavy metal concentrations
were recorded. Strong negative correlation between macrobenthic diversity and heavy metal concentrations was found, and this
implicated the pollution-induced degradation of macrobenthos in some locations in Tolo Harbour. These results support the
Pearson–Rosenberg model for succession along a pollution gradient. |
