| This work is based on about 2,000 samples. It provides a synthetic description of the distribution patterns of fûraminiferal assemblages in paralie environments and shows on two examples the effect of anthropogenic impacts. It shows that despite the great diversity of eeological parameters, foraminiferal assemblages are naturally distributeà along a fev/ major gradients. Anomalies in these distribution patterns or morphological abnormalities of the tests indicate anthropogenic or natural stresses. An increase in the number of individuals, specifie richness and test size indicate organic pollution while chemicai pollution as an inverse effect. ln Port-Joinville harbour, Cribroelphidium excavatum and Haynesina gennanica characterize the areas submited to the... |
