P7: Distribution of planktic communities in Upper Lake Constance

In this project, we will investigate the patchiness and dynamics of the zooplankton and phytoplankton distribution in the context of relevant limnological parameters. For this purpose, we will develop a measurement concept that will be implemented for a period of one year. In addition to traditional microscopic identification, this concept also comprises hydroacoustic, fluorescence-optical and molecular-biological methods. The data of the patchiness monitoring will be linked to existing measurements from the joint monitoring of the states bordering Lake Constance. We aim to test and establish new measuring procedures for environmental observation, and to better understand the processes that shape the spatial and temporal distribution patterns, based on optimised monitoring. We will obtain information about interactions and dependencies within the limnic ecosystem, and the responses of communities to changing environmental conditions. These results are essential for water conservation and the protection and conservation of biodiversity.
