We conducted several hundreds of projects successfully since 1980. We point out two of them since they are special to us. The first one is special since this is the only project so far that has been paid by a French waterauthority (D.I.R.E.N.) In this project we participated together with Ecoconsult and Waterfauna. The second one is special because it concerns subfossil desmid communities and their response to acidification in soft water.
An impression of the other projects can be obtained from the Bibliography.
