Benthic foraminifera as bioindicators of anthropogenic impacts in two north African lagoons: a comparison with ostracod assemblages

摘要

Numerous investigations have used the foraminiferal assemblages or species as bioindicators.This paper tests the responses of these microorganisms to different environmental changes (heavy metalpollution, treatment stations, artificial inlets, agricultural and urban sewages) and compares them tothose observed previously on ostracod assemblages. Foraminifera are more tolerant to these changes,while ostracods present a more specialized response.
