Somit ergibt sich die Frage, in welcher Weise die Respirationintensitat von verschiedenen Typen von Wasserpflanzen (Susswasser- und Meeresalgen,sowie hohere Wasserpflanzen) gegensuber unter streng kontrollierten Laboratoriumsbedingungen,auf eine Erniedringung bzw, Erhohung des Sauerstoffgehaltes des Wasser reagieren, wobei verschiedene Verhaltenstypen bestatigt werden konnte, die einen Einblick in den oecologischen Wechselwirkungen zwischen "Organismus" und "Lebensraum" ermoeglichen.
