Ökosystemforschung am Bodensee – der See ändert sich grundlegend.

Ökosystemforschung am Bodensee. Abschluss des Forschungsprojekts SeeWandel: Leben im Bodensee – gestern, heute und morgen.
An article by Josephine Alexander, Markus Möst, Dietmar Straile, Harald Hetzenauer and Piet Spaak.
published on Juni 5, 2023 in the journal “AQUA & GAS”

Lake Constance in a state of change. Rising temperatures, invasive species and other factors have changed the composition of species in Lake Constance over the last century. Researchers are trying to understand how this could have happened and what it means for the lake.
An interview with Piet Spaak.

„Das Ökosystem Bodensee mit seinen Prozessen und Funktionen umfassend verstehen“. Der Einfluss verschiedener Stressfaktoren auf das Ökosystem Bodensee und dessen Resilienz stehen im Mittelpunkt von zwei aktuellen, breit angelegten und sich gegenseitig ergänzenden Forschungsprojekten. Das eine der beiden mit dem Titel „SeeWandel: Leben im Bodensee – gestern, heute und morgen“ wird im Interview von Projektleiter Piet Spaak (Eawag) vorgestellt. Er berichtet von den Zielen des Projekts und den verschiedenen Forschungsfragen sowie ersten Ergebnissen rund um Nährstoffe, Klimawandel, Quaggamuscheln, Stichlingen und vieles mehr.
