Quelques peuplements malacologiques ayant contribue aux comblements du marais poitevin actuel (Vendee et Charente-Maritime)
Four cores have been sampled in the "Marais Poitevin": one of them in the east of Charron, another one near Pied-Lizet and the others near Maillezais. Pieces of shells of different species have been numbered and weighed. Ranks frequencies diagrams show the malacological associations homogeneity and diversity. The factorial analysis on the absences-presences makes clear an ecological gradient from the most marine associations to the most superficial and finally land associations.
