Dynamic Food Webs challenges us to rethink what factors may determine ecological and evolutionary pathways of food web development. It touches upon the intriguing idea that trophic interactions drive patterns and dynamics at different levels of biological organization: dynamics in species composition, dynamics in population life-history parameters and abundances, and dynamics in individual growth, size and behavior. These dynamics are shown to be strongly interrelated governing food web structure and stability and the role of populations and communities play in ecosystem functioning.Dynamic Food Webs not only offers over 100 illustrations, but also contains 8 riveting sections devoted to an understanding of how to manage the effects of environmental change, the protection of biological diversity and the sustainable use of natural resources.Dynamic Food Webs is a volume in the Theoretical Ecology series.- Relates dynamics on different levels of biological organization: individuals, populations, and communities- Deals with empirical and theoretical approaches- Discusses the role of community food webs in ecosystem functioning- Proposes methods to assess the effects of environmental change on the structure of biological communities and ecosystem functioning- Offers an analyses of the relationship between complexity and stability in food webs

Presenting new approaches to studying food webs, this book uses practical management and policy examples to demonstrate the theory behind ecosystem management decisions and the broader issue of sustainability. All the information that readers need to use food web analyses as a tool for understanding and quantifying transition processes is provided. Advancing the idea of food webs as complex adaptive systems, readers are challenged to rethink how changes in environmental conditions affect these systems. Beginning with the current state of thinking about community organisation, complexity and stability, the book moves on to focus on the traits of organisms, the adaptive nature of communities and their impacts on ecosystem function. The final section of the book addresses the applications to management and sustainability. By helping to understand the complexities of multispecies networks, this book provides insights into the evolution of organisms and the fate of ecosystems in a changing world.

Die Landwirtschaft in Deutschland, Europa und weltweit befindet sich in einem dramatischen Umbruchprozess. Einerseits bieten Liberalisierung und Marktöffnung, neue technologische Entwicklungen, die wachsende Weltbevölkerung und neue Kundenwünsche vielen landwirtschaftlichen Betrieben neue Möglichkeiten. Andererseits stehen viele Landwirtinnen und Landwirte in internationaler Konkurrenz, sind zum betrieblichen Wachstum mit hohem Investitionsrisiko gezwungen, sind Teil strikt regulierter Wertschöpfungsketten und müssen steigenden gesellschaftlichen Ansprüchen genügen. Zugleich machen sich viele Menschen Sorgen, dass die Prozesse der Rationalisierung und Modernisierung der landwirtschaftlichen Produktion auf Kosten von Natur-, Umwelt- und Tierschutz gehen. Auf vielen Ebenen wird daher bereits nach einer neuen Verständigung darüber gesucht, was die Gesellschaft von der Landwirtschaft erwartet, und welche Unterstützung die Landwirtinnen und Landwirte im Gegenzug dafür erwarten dürfen. Vor diesem Hintergrund entwickelt das vorliegende Open Access-Buch eine wissenschaftlich fundierte Kritik der Umweltauswirkungen der Landwirtschaft und der politischen Logik der Agrarpolitik. Es präsentiert ein neues Leitbild mit konkreten Indikatoren sowie alternative strategische Handlungsoptionen. Die umfassende Analyse wird zu einem Vorschlag für eine neue Architektur der europäischen Agrarpolitik gebündelt, die eine breite Diskussion um einen Neuen Gesellschaftsvertrag für die Landwirtschaft in Deutschland und Europa anstoßen soll.
