Pasture Landscapes and Nature Conservation
One of the main problems and aims of nature conservation in Europe is to protect semi-open landscapes. The development during the past decades is characterized by an ongoing intensivation of land use on the one hand, and an increasing number of former meadows and pastures lying fallow caused by changing economic conditions on the other hand. In several countries the estabishment of larger "pasture landscapes" with a mixed character of open grassland combined with shrubs and forests has been recognized as one solution to this problem. The book gives an overview of the European projects concerning to this topic - nature conservation policy and strategies, scientific results and practical experiences creating large scale grazing systems.
The Death of Our Planet's Species
The present rate and extent of species extinction -- estimated by some scientists as one species every 20 minutes -- are unprecedented in the history of mankind. Human activities are responsible for nearly all species loss, yet ethical aspects of this crisis are rarely mentioned. Any concern expressed tends to be over potentially valuable resources -- information for scientists, or compounds that could be used in new medicines -- that are lost when a species disappears. In The Death of Our Planet's Species, Martin Gorke argues that such a utilitarian perspective is not only shortsighted but morally bankrupt. Holding doctoral degrees in both ecology and philosophy, Gorke is uniquely qualified...

Database and Expert Systems Applications
DEXA 2004, the 15th International Conference on Database and Expert Systems Applications, was held August 30 ? September 3, 2004, at the University of Zaragoza, Spain. The quickly growing spectrum of database applications has led to the establisment of more specialized discussion platforms (DaWaK Conference, EC-Web Conference, EGOVConference, Trustbus Conference and DEXA Workshop: Every DEXA event has its own conference proceedings), which were held in parallel with the DEXA Conference also in Zaragoza. In your hands are the results of much effort. The work begins with the preparation of the submitted papers, which then go through the reviewing process. The accepted papers are revised to fin...
Database and Expert Systems Applications
DEXA 2005, the 16th International Conference on Database and Expert Systems Applications, was held at the Copenhagen Business School, Copenhagen, Denmark, from August 22 to 26, 2005. The success of the DEXA series has partly been due to the way in which it has kept abreast of recent developments by spawning specialized workshops and conferences each with its own proceedings. In 2005 the DEXA programme was co-located with the 7th International Conference on Data Warehousing and Knowledge Discovery [DaWaK 2005], the 6th International Conference on Electronic Commerce and Web Technologies [EC-Web 2005], the 4th International Conference on Electronic Government [EGOV 2005], the 2nd International...
Mediation
Mediation provides an attractive alternative to resolving disputes through court proceedings. Mediation promises just results in the interest of all parties concerned, a reduction of the court caseload, and cost savings for the parties involved as well as for the treasury. The European Directive on Mediation has given mediation in Europe new momentum by establishing a common framework for cross-border mediation. Beyond Europe, many states have tried in recent years to answer the question whether, and if so, how mediation should be regulated at a national and international level. The aim of this book is to promote the understanding and discussion of regulatory issues by presenting comparative...
Vertical Food Web Interactions
In the past years, much work has been carried out on either life-history evolu tion or structure and function of food webs. However, most studies dealt with only one of these areas and often touched upon the other only marginally. In this volume, we try to synthesize aspects of both disciplines and will concen trate on how the interactions between organisms depend on their life-history strategies. Since this is a very comprehensive topic, this volume will focus on vertical interactions to remain within a clearly arranged field. We present some scenaria based on life-history variation of resource and consumer, and show how particular patterns of life-history combinations will lead to particul...
Flux Control in Biological Systems
Comprehending and modelling biomass production, nutrient, and water fluxes in biological systems requires understanding control mechanisms at various levels of organiztion. This new book, with 16 pages of four-colorplates, compares patterns and mechanisms of regulation-starting from enzyme reactions and ending at the population and ecosystem level. By doing so, the book investigates the general principles of how fluxes are adjusted and regulated. Such principles areessential for preparing effective models and for predicting human impacts on ecosystems. Flux Control in Biological Systems: From Enzymes to Populations and Ecosystems will be an essential personal library addition for student and professional environmental biologists, ecologists, physiologists, biochemists, botanists, microbiologists, soil scientists, and zoologists; as well as anyone who investigate patterns of matter and energy transfer in biological systems of different levels of complexity.* Presents the mechanisms of flux control* Explains the similarities of flux control at various levels of complexity and organization* Demonstrates how fluxes are adjusted in complex systems of interacting groups of organisms
Aphids as Crop Pests, 2nd Edition
Aphids are among the major global pest groups, causing serious economic damage to many food and commodity crops in most parts of the world. This revision and update of the well-received first edition published ten years ago reflects the expansion of research in genomics, endosymbionts and semiochemicals, as well as the shift from control of aphids with insecticides to a more integrated approach imposed by increasing resistance in the aphids and government restrictions on pesticides. The book remains a comprehensive and up-to-date reference work on the biology of aphids, the various methods of controlling them and the progress of integrated pest management as illustrated by ten case histories.
