Comparison of gravisensing organs in different zooplankton organisms – evolution and morphology
The high reproductive output and the essential role in aquatic food webs suggest especially aquatic zooplankton species to be suitable for life support systems. Considering the broad range of gravity-perception systems there is still a considerable lack of knowledge for zooplankton species regarding this aspect. Hence, the purpose of the current project is to develop a highly representative comparison of gravity-perception systems in selected zooplankton organisms with special emphasis on their evolutionary history. In addition, sensitivity windows in ontogeny and thresholds of graviperception will be analysed in selected organisms. Moreover, ground based studies will be performed to investigate the effects of reduced gravity on life history of the selected zooplankton species. The outcome will foster the selection of zooplankton species for life support systems and additionally significantly increase knowledge on the evolution of graviperception in aquatic ecosystems. It also may elucidate general gravity-related mechanisms valid for other organisms as well.
