"How can we increase the production and harvest of living marine resources in the new millennium? Bridging potentials and environmental constraints". This was the theme of the 1st Maricult Conference arranged in Trondheim, Norway in June 2000 in connection with termination of the Norwegian research programme Maricult (1996-2000; www.maricult.org). The intention for the conference was not only to present a state of the art overview of the research conducted as part of the programme, but also to describe other experiences and to discuss the ideas and the scientific status of the programme with the international scientific community. A total of 50 oral communications and 8 posters were presented at the conference. Sixteen of them are included in the present volume. They deal with such topics as strategies for improving marine harvest, underlying mechanisms for marine productivity, new concepts of mariculture with emphasize on mussels, and nutrient supply and environmental impact.
How can natural and cultural values be a resource for sustainable development? That is the question the Nordic Blue Parks project has tried to answer by providing case-studies of regional and local success stories, thereby assessing the possible synergistic effects of cross-sectoral working with both nature- and cultural heritage bodies. Nordic Blue Parks is a new concept that combines underwater nature and cultural trails in four Nordic countries, i.e. Finland, Sweden, Norway and Denmark.The Nordic Blue Parks project has created an international forum to foster ties not only between the various groups working regionally on this project, but also to engender links between the general public and their own cultural and natural resources. Through this project both natural and cultural administrations from several Nordic countries have for the first time cooperated concerning the underwater environment. The Nordic Blue Parks project ably integrates components of sustainable development and provides new economic possibilities to develop local natural tourism, international cooperation, education and research, as well as cultural identity.
The present text compiles the latest research within the field of biology performed in the Baltic Sea area. The themes span from theoretical and philosophical aspects of the ecosystem concept over population and autecological studies to detailed descriptions of plant and animal physiology. Results from microcosm and mesocosm experiments as well as direct observations in field together bring insight of the special structure and function of the Baltic Sea ecosystem. How the spawning success of cod and spat are dependent of each other and environmental factors, the impact of alien species to the composition of plankton or benthic communities, the flip of phytobenthic to planktonic communities in lagoons and mechanisms triggering the change, pure descriptions of e.g. the Estonian coast and shallow off shore areas as well as strategies for the reproductive success of Fucus vesiculosus, and the influence of eutrophication of the different Baltic Sea areas and the fate of pollutants as radionucleids and PAH etc. and other themes are all discussed in the 24 original papers of this volume.
Presents experimental studies of kinetics, configuration, and hydrodynamic properties of adsorbed polymer chains at colloidal surfaces. Describes flocculation and stabilization of colloidal particles in solutions containing adsorbing or nonadsorbing uncharged polymers or polyelectrolytes. Highlights theoretical and computer simulation studies of the structure and dynamics of polymers adsorbed at interfaces. Discusses interactions of macromolecules with micelles, bilayers, liposomes, and proteins.
