The journal is concerned with fundamental studies on structure, function, dynamics and classification of plant-dominated aquatic ecosystems. It is also intended as an outlet for papers dealing with applied research on aquatic plants, including reports on the consequences of disturbance of aquatic ecosystems (e.g. transplantations, influence of herbicides and other chemicals, thermal pollution, biological control, grazing and disease), the use of aquatic plants, conservation of resources and all aspects of plant production and decomposition.
