Honighäuschen (Bonn) - Newly developed and innovative methods are mentioned and outlined so that the book can be used as a source of information for scientists and professionals specialised in the treatment of soils as well as for students in courses of environmental studies. The book offers a short, compressed overview of the important features of this subject and can be used as a reference book of the state of the art. The appendix offers the interested reader a detailed survey of materials, test methods and apparatuses as well as a description of analytical directions and processes.

Honighäuschen (Bonn) - Symbiosis is the fourth volume in the series Cellular Origin and Life in Extreme Habitats (COLE). Fifty experts, from over a dozen countries, review their current studies on different approaches to these phenomena. The chapters present various aspects of symbiosis from gene transfer, morphological features, and biodiversity to individual organisms sharing mutual cellular habitats. The origin of the eukaryotic phase is discussed with emphasis on cyanelles, H syntrophy, N2 fixation, and S-based symbiosis (as well as the origin of mitochondrion, chloroplast, and nucleus). All members of the three domains of life are presented for sharing symbiotic associations. This volume brings the concept of living together as `One plus One (plus One) equals One.' The purpose of this book is to introduce the teacher, researcher, scholar, and student as well as the open-minded and science-oriented reader to the global importance of this association.

Honighäuschen (Bonn) - The present paper gives an overview about the Lake Hiidenvesi Research Project which was built to clarify the structure and function of the food web of eutrophic, clay-turbid lakes. Lake Hiidenvesi ist situated in southern Finland and it consists several separate basins with variable water quality. Studies of the role of bacteria, phytoplankton, macrophytes as well as planktivorous and piscivorous fish in the food webs were performed. The results of the project have implications for lake restoration, since the effects of clay-turbidity on the effectivity of food web management are poorly known.

$Honighäuschen (Bonn) - In March 23rd 1986, a small group of scientists from 11 countries met at the Department of Limnology, University of Vienna, to discuss sediment phosphorus problems. The discussions lasted three days during which twenty lectures were delivered and discussed under the following headings: 1. Sedimentation, 2. Release, 3. Bioavailability and 4. Fractionation of P. The final day was devoted to summarize the information gathered and to make proposals for future research. Four working groups were formed for this task. In the first group (Sedimentation) the sources, transport and transformation processes of particulate phosphorus during sedimentation were discussed. The second group (Release) was dealing with concepts, causes and consequences of phosphorus fluxes through the interface. Group number three (Bioavailability) treated the availability of different P compounds to organisms, and group four (Fractionation) tried to summarize and to update the present knowledge of fractionation methods. Some of the original papers presented at the meeting appear in this volume$
