Water and energy are crucial to sustainable development, both globally and within Germany. WANDEL focuses on the question of whether limited water availability restricts the use of conventional energy systems and thereby accelerates the energy transition, or whether it actually slows the transition down.
Our proposal aims to use existing size data of fish and their prey in lakes obtained for European monitoring programs (EU Water Framework Directive) and from several lake-specific research programs to test whether predator-prey interactions and resource subsidy modify the size-density relationships of fish and fish prey as predicted by the Energetic Equivalence Hypothesis
Woody riparian buffer strips along rivers have widely been used mainly to reduce nutrient and fine sediment input from agricultural areas but potentially offer many more ecosystem services (e.g. habitat provision increasing biodiversity, shading and temperature regulation, mitigating climate change effects).
New scientific publications about the taxonomy of small suspended algae, called phytoplankton will be implemented into an update of the German taxa list. This update is needed to ensure uniform identification and coding of indicator species used for the assessment of the ecological status of lakes and rivers in Germany.
