Introduction The Fourth Symposium on Sediment/Water Interactions was held in Melbourne, Australia, February 16-20th, 1987. The previous three symposia were held in Amsterdam, Kingston (Ontario), and Geneva, In keeping with the approach established in Geneva, contributions addressed sediment/water interactions related to both fresh and salt water conditions. More than 160 papers were given in Melbourne, including more than 20 poster presentations, and collected Abstracts are available from Dr. B. T. Hart. A total of 51 papers, subsequently, have been published as proceedings of the Melbourne Symposium; 45 of these appear in this issue of Hydrobiologia. A further six appeared earlier as a selection of papers in J. Environ. Geol. and Water Science (1988, issue # 1); these six papers appear in abstract form, only, in the present pUblication. Although concerned with the global environment, the International Association for Sediment Water Science attempts to ensure that there is a genuine opportunity for participants to focus on regional issues throughout the world and, in particular, to provide a local forum for their presentation. The Melbourne meeting was particularly successful in achieving this objective, and Australasia was well represented by about 36 percent of the contributors. About 27 percent were from Europe, 17 percent from North America, 7 percent from China and Japan, 7 percent from Southeast Asia and India, and about 6 percent came from other areas. In all, 25 countries were represented.

Skickas inom 10-15 vardagar
An understanding of the ecology of a fish pond is essential for the achievement of steady and high fish production in ponds. For the ecologist, the fish pond is a small laboratory: easy to investigate and responding rapidly to manipulation. For the aquaculturist, the ecology shows the ways and means of interventions ensuring an increase of production. The book deals with the different aspects of natural production within a pond, referring it to African conditions: considering first the role of soil as source and sink of nutrients for the water, then nutrient cycling within water and the fate of fertilizers added to ponds, and finally the contribution of natural productivity to fish production. The important sum of information brought together in this volume is valuable for both aquaculturist and ecologist, who lack a handbook on the ecology of a fish pond. It will capture the interest of African aquaculturists and stimulate aquaculture research on natural production.
Dissolved Organic Matter in Lacustrine Ecosystems
Energy Source and System Regulator

Skickas inom 10-15 vardagar
Concentrations of dissolved organic matter (DOM) in lakes are often an order of magnitude greater than concentrations of particulate organic matter; nevertheless, the biogeochemical analysis of DOM is described in only a few textbooks on limnology (most thoroughly by Wetzel). The origins of dissolved organic substances are largely photosynthetic; DOM is either autochthonously synthesized by littoral and pelagic flora through secretions and autolysis of cellular contents, or allochthonously generated in terrestrial systems of the drainage basin, composing largely of humic substances refractory to rapid microbial degradation. The role of DOM in lacustrine ecosystems, as energy source and system regulator, however is still relatively poorly known. The aim of the book is to present state-of-the-art reviews of the role of dissolved autochthonous and allochthonous organic matter in pelagial and littoral zones, and to focus attention on poorly understood but critical topics and hence to provide direction for future research activity.

The volume starts with comparative reservoir limnology and deals with problems relating tropical, semi-arid and temperate reservoirs. The second part concerns mathematical models of reservoirs, including new techniques for investigating their limnology. These cover physical, chemical and biological phenomena, remote sensing and the use of modelling to establish the most efficient strategy for water quality sampling. In the third part, on reservoir water quality management, the potential available in fish population management for biomanipulation of reservoir water quality is introduced. Also included is a valuable section on a wide range of water quality measures, coming from the well-known Czech hydrobiological laboratory. Finally the editors summarize the present state of reservoir limnology. This book should be of interest to hydrobiologists and aquatic ecologists, reservoir and sanitary engineers, fisheries officers, postgraduate teaching, and the water industry dealing with drinking water supply and will provide insight into regulated rivers. It draws information from all over thye world and is relevant to the whole world.

The limnological study of Toolik Lake began in the Summer of 1975. This research was an outgrowth of the arctic IBP project which had focused mainly on small Arctic pond ecosystems on the Alaskan Arctic coastal plain. It was thought desirable to study larger, deeper lakes which contained fish to further generalizations developed during the IBP study. Initial research on Toolik Lake and the surrounding lakes and ponds focused on process studies such as annual primary productivity of the lake or the vertical migration patterns of the resident zooplankton. In 1983 the philosophy of the research changed with the funding of a more integrated programmer. The fundamental question posed was whether Arctic lake and stream ecosystems are regulated from the bottom up by nutrient availability or from the top down by the density and activity of top predators. In 1987 the Toolik Lake area was designated an LTER (Long-Term Ecological Research) site, one of 18 such sites throughout the United States, Puerto Rico, and the Antarctic. The research theme for the Arctic LTER also focuses on the regulation of Arctic ecosystems, whether regulation comes from the top down or bottom up.The Arctic LTER also incorporates a terrestrial component as well as a lake and stream component.

The mangrove, seagrass and coral reef ecosystems are of paramount ecological importance but have already undergone great degradation, which is advancing at an alarming rate. If present trends continue, the natural resource basis of the economy and ecology of tropical coastal regions will soon be ruined. This was the unanimous conclusion of the 110 scientists from 23 countries who gathered in Mombasa, Kenya, for a Symposium on the ecology of these ecosystems. Mangrove forest systems yield large amounts of fish, crabs, prawns and oysters. They are also valuable sources of fuelwood, timber, tannin and other natural products. Their non-marketable value is of equal importance: stabilization of the coastline, an indispensable nursery ground for numerous marine species with commercial value, a natural filter maintaining the clarity of nearshore water, a home for resident and migratory birds and other wildlife. Many of the true mangrove flora and fauna are now endangered by the clearing of the mangroves. It has been shown that in many countries between 25 and 100% of the mangrove forest has been destroyed alraedy in the last twenty years. The international scientific assembly concluded that much can be done to stop the degradation of these damaged ecosystems and to rehabilitate them. But new techniques must be found to use them on a sustainable basis for long-term economic return and for the well-being of coastal human settlements and a healthy environment.

Ecotones, or boundary zones between land and inland waters (such as lakes, streams and rivers), are the principal routes for transport of organic matter and nutrients across landscapes via physical and biological vectors. The ecotone is the place of cumulation and transformation of in situ production as well as of allochthonous material from adjacent aquatic and terrestrial systems. The ecotype functions as an important barrier or filter for principal nutrients, such as phosphorus and nitrogen, responsible for the eutrophication and degradation of surface waters. Intensive forest cutting, agriculture, pollution and bank regulation, urbanization and hydrotechnical constructions seriously endanger the ecotone systems and damage their protective function. It is vital to develop a scientific understanding of the behaviour of phosphorus and nitrogen in these transitional boundary habitats. Such an understanding is important for the rational protection, management and restoration of ecotones connected with lakes and rivers.The importance of nutrient cycling and retention is discussed here from the point of view of ecotone function, management and reconstruction in order to sustain its protective role for water bodies. Various types of land/water transitory zones are discussed: wetlands, lake littoral systems, riparian zones of rivers, streams and brooks, the contact zones between groundwater and surface waters of lakes and rivers, air-water interfaces, and patch/ecotone structures in watersheds.

For the first time a paper was presented on the historical aspects of Rotiferology, covering European research between 1680-1950. A special workshop session was devoted to a debate on a controversial topic: Rotifer Phylogeny. The workshop resulted in a very successful discussion and the integration of scattered evidence and hypotheses on the phylogenetic origin of rotifers, the relationships between major rotifer groups, and the mechanisms of evolution.

Industrial seaweed use started in Brittany in the XVII century. Today, 700 species have been identified along 1000 km of shoreline, producing 10 million tons of biomass. In the Fourteenth International Seaweed Sumposium the latest developments in the area are discussed. The blending of molecular biology with traditional taxonomy is improving our understanding of phylogeny and species relationships among many of the important algae. A new generation of biologically-based management models is gradually incorporating field testing, concepts from ecological theory and principles from population biology. Prediction is being improved, and an appropriate balance is being struck between commercial exploitation and the preservation of wild seaweed resources. Cell and tissue culture of seaweeds is entering the mass-production phase. Field farming is now entering the large-scale production area. New, biologically active compounds are being described, obtained from algae, and new tools for the characterisation of phytocolloids are described. Microalgal blooms and toxins are also experiencing a flourish of new results.
