About this book

Food webs have now been addressed in empirical and theoretical research for more than 50 years. Yet, even elementary foundational issues are still hotly debated. One difficulty is that a multitude of processes need to be taken into account to understand the patterns found empirically in the structure of food webs and communities.

Food Webs and Biodiversity develops a fresh, comprehensive perspective on food webs. Mechanistic explanations for several known macroecological patterns are derived from a few fundamental concepts, which are quantitatively linked to field-observables. An argument is developed that food webs will often be the key to understanding patterns of biodiversity at community level.

Food Webs and Biodiversity is a highly topical book which will be of interest to a wide ranging audience, including not only graduate students and practitioners in community and conservation ecology but also the complex-systems research community as well as mathematicians and physicists interested in the theory of networks.

"This is a comprehensive work outlining a large array of very novel and potentially game-changing ideas in food web ecology."
- Ken Haste Andersen, Technical University of Denmark

 "I believe that this will be a landmark book in community ecology [...] it presents a well-established and consistent mathematical theory of food-webs. It is testable in many ways and the author finds remarkable agreements between predictions and reality."
- Géza Meszéna, Eötvös University, Budapest

Axel G. Rossberg obtained an M.A. in theoretical physics at the University of Texas at Austin and a Ph.D. in complex-system physics at the University of Bayreuth. Since 2003 he is specializing on food-web theory and community ecology. To foster applications in the management context he recently joined UK's Centre for Environment, Fisheries & Aquaculture Science (Cefas). He is also Senior Research Fellow at Queen's University Belfast and Honorary Lecturer at University of East Anglia, and serves on the editorial board of The American Naturalist.
