Short summary
For water managers, analysing time variations in short and incomplete bioindicator series is necessary but tricky. From our work on benthic invertebrate indicator series sampled in the Saône basin (France), we conclude that (1) combining statistical tests and graphical analyses is relevant for classifying time series, (2) environmental contexts explain similarities between series better than river size classes, (3) a single value can summarise a serie to link bioindicators to land-use stressors.
