Gegenstand dieses Schwerpunktprogramms sind beobachtende, experimentelle und modellierende Untersuchungen zu den Auswirkungen des prognostizierten Klimawandels auf aquatische Ökosysteme. In Übereinstimmung mit den meisten Klimaprognosen für unsere Region soll das Schwergewicht auf den Auswirkungen saisonaler Temperaturerhöhungen (Schwerpunkt der Erwärmung im Winter) liegen, für Fließgewässer auch auf dem Problem häufiger werdender Extremereignisse. Wegen der unterschiedlichen Auswirkungen der prognostizierten Erwärmung auf vorwiegend lichtabhängige Prozesse (Primärproduktion) und vorwiegend temperaturabhängige Prozesse (z.B. Wachstum heterotropher Organismen) werden nicht nur veränderte saisonale Aktivitäts- und Wachstumsmuster einzelner Arten, sondern in der Folge auch Verschiebungen in trophischen Interaktionen (Herbivorie, Räuber-Beute-Systeme) erwartet. Bisherige zeitliche Kopplungen von Angebot und Nachfrage (z.B. Verfügbarkeit geeigneter Nahrung und Bedarf durch bestimmte Lebenszyklusstadien der Konsumenten) könnten entsynchronisiert werden ("mismatch"). Die Folgen derartiger Entkopplungen für die Funktion und Entwicklung von Nahrungsnetzen soll die zentrale Frage des Schwerpunktprogramms sein.
