Fig. 7 Temporal variations in IPR scores in four successive sectors of the Seine River, from the
confluence with the Aube River to the beginning of the estuary. A decrease in index values
corresponds to an improvement in the state of the fish community. Smoothing curves were
constructed using LOWESS tools (see Fig. 6 for location of the four sectors)
