| Abstract: | An analysis is presented of some intertidal meiofauna assemblages from the Firth of Clyde. The results cast doubt on the validity of the nematode/copepod ratio as a means of assessing marine pollution. In the light of this analysis, data from the literature on the meiofauna assemblages of the Firth of Clyde are reinterpreted. It is concluded that the ratio is unreliable because (a) it oversimplifies a highly complex set of relationships and (b) nematode and copepod populations may react independently to a variety of environmental parameters, of which pollution is only one. In these circumstances it is suggested that the ratio should be abandoned as a practical pollution indicator. |
