| Summary: | A study was carried out in the Forth estuary (Scotland) to determine the impact of industrial effluents on
the nematodes and harpacticoid copepods species of an estuarine mudflat. The nematodes and harpacticoid
copepods species in the area ranging from the species which are absent from the vicinity of the effluents to
the species which occure predominantly in the most highly polluted sediments display a spectrum of responses
to the discharges. It is thought at least some of the species favouring the immmediate vicinity of the effluent
channels would be associated with the dense microalgal mat that fringes the channels. Two factors seemed
to be dominant in controlling the species distribution of nematodes and harpacticoid copepods in the area
interdal height and pollution. Cluster analysis of the species abundance data from the sampling stations "clearly
showed the separation of sites on the upper, middle and lower shore. The ordination of the stations was
also strongly influenced by intertidal height superimposed by pollution. |
