Heterogeneity of periphyton in French Mediterranean riversta. We also sampled simultaneously measurements of water quality and other relevant environmental variables. All investigations in mediterranean area show the high sensibility of periphyton reacting quickly to environmental parameters; it is shown by a heterogeneous pattern of colonization at different levels.

Assessment of the bio-indicator capacity of aquatic macrophytes using multivariate analysisligotrophic waters; . for eutrophicated waters and . for high nitrate levels. Five species groups characterizing the geology and mineralization as well as the perturbations in the quality of the water or the environment were identified (e.g. pollution, eutrophication, reposition and reshaping).
