Self-organization in biological systems / Camazine, S. ; Deneubourg, J.-L. ; Franks, N.R. ; Sneyd, J. ; Theraulaz, G. ; Bonabeau, E. (2001)

Public ISBD Titre : Self-organization in biological systems Type de document : livre Auteurs : Camazine, S. ; Deneubourg, J.-L. ; Franks, N.R. ; Sneyd, J. ; Theraulaz, G. ; Bonabeau, E. Editeur : Princeton, New Jersey : Princeton University Press Année de publication : 2001 Collection : Princeton studies in complexity Importance : 538 p. ISBN/ISSN/EAN : 978-0-691-11624-2 Note générale : Inventaire 2008: Pointé en rayon le 10/04/2008 Langues : Anglais (eng) Mots-clés : Biological systems  Self regulatory organizations Résumé : The synchronized flashing of fireflies at night. The spiraling patterns of an aggregating slime mold. The anastomosing network of army-ant trails. The coordinated movements of a school of fish. Researchers are finding in such patterns--phenomena that have fascinated naturalists for centuries--a fertile new approach to understanding biological systems: the study of self-organization. This book, a primer on self-organization in biological systems for students and other enthusiasts, introduces readers to the basic concepts and tools for studying self-organization and then examines numerous examples of self-organization in the natural world. Self-organization refers to diverse pattern formation processes in the physical and biological world, from sand grains assembling into rippled dunes to cells combining to create highly structured tissues to individual insects working to create sophisticated societies. What these diverse systems hold in common is the proximate means by which they acquire order and structure. In self-organizing systems, pattern at the global level emerges solely from interactions among lower-level components. Remarkably, even very complex structures result from the iteration of surprisingly simple behaviors performed by individuals relying on only local information. This striking conclusion suggests important lines of inquiry: To what degree is environmental rather than individual complexity responsible for group complexity? To what extent have widely differing organisms adopted similar, convergent strategies of pattern formation? How, specifically, has natural selection determined the rules governing interactions within biological systems? Broad in scope, thorough yet accessible, this book is a self-contained introduction to self-organization and complexity in biology--a field of study at the forefront of life sciences research.

Robustness and evolvability in living systems / Wagner, Andreas (2005)  

Public ISBD Titre : Robustness and evolvability in living systems Type de document : livre Auteurs : Wagner, Andreas Editeur : Princeton, New Jersey : Princeton University Press Année de publication : 2005 Collection : Princeton studies in complexity Importance : 367 p. ISBN/ISSN/EAN : 978-0-691-12240-3 Note générale : 2 ex. Langues : Anglais (eng) Mots-clés : Biological systems  Molecular evolution  Mutation  Robust control  Stability Résumé : All living things are remarkably complex, yet their DNA is unstable, undergoing countless random mutations over generations. Despite this instability, most animals do not grow two heads or die, plants continue to thrive, and bacteria continue to divide. Robustness and Evolvability in Living Systems tackles this perplexing paradox. The book explores why genetic changes do not cause organisms to fail catastrophically and how evolution shapes organisms' robustness. Andreas Wagner looks at this problem from the ground up, starting with the alphabet of DNA, the genetic code, RNA, and protein molecules, moving on to genetic networks and embryonic development, and working his way up to whole organisms. He then develops an evolutionary explanation for robustness. Wagner shows how evolution by natural selection preferentially finds and favors robust solutions to the problems organisms face in surviving and reproducing. Such robustness, he argues, also enhances the potential for future evolutionary innovation. Wagner also argues that robustness has less to do with organisms having plenty of spare parts (the redundancy theory that has been popular) and more to do with the reality that mutations can change organisms in ways that do not substantively affect their fitness. Unparalleled in its field, this book offers the most detailed analysis available of all facets of robustness within organisms. It will appeal not only to biologists but also to engineers interested in the design of robust systems and to social scientists concerned with robustness in human communities and populations.

Principles of terrestrial ecosystem ecology / Chapin, F.S. (2011)  

Public ISBD Titre : Principles of terrestrial ecosystem ecology Type de document : livre Auteurs : Chapin, F.S., Auteur ; Matson, P.A., Auteur ; Vitousek, P.M., Auteur Mention d'édition : 2nd ed. Editeur : New York : Springer Année de publication : 2011 Importance : 529 p. ISBN/ISSN/EAN : 978-1-4419-9502-5 Note générale : Voir aussi la 1ère édition de 2002 à la cote 67407/15 Langues : Anglais (eng) Mots-clés : Applied Ecology  Biogeochemical cycles  Biological systems  Ecosystem management Résumé : L'éditeur indique : Humans have directly modified half of the ice-free terrestrial surface and use 40% of terrestrial production. We are causing the sixth major extinction event in the history of life on Earth. With the Earth’s climate, flora, and fauna changing rapidly, there is a pressing need to understand terrestrial ecosystem processes and their sensitivity to environmental and biotic changes. This book offers a framework to do just that. Ecosystem ecology regards living organisms, including people, and the elements of their environment as components of a single integrated system. The comprehensive coverage in this textbook examines the central processes at work in terrestrial ecosystems, including their freshwater components. It traces the flow of energy, water, carbon, and nutrients from their abiotic origins to their cycles through plants, animals, and decomposer organisms. As well as detailing the processes themselves, the book goes further to integrate them at various scales of magnitude—those of the ecosystem, the wider landscape and the globe. It synthesizes recent advances in ecology with established and emerging ecosystem theory to offer a wide-ranging survey of ecosystem patterns and processes in our terrestrial environment. Featuring review questions at the end of each chapter, suggestions for further reading, and a glossary of ecological terms, Principles of Terrestrial Ecosystem Ecology is a vitally relevant text suitable for study in all courses in ecosystem ecology. Resource managers and researchers in many fields will welcome its thorough presentation of ecosystem essentials.
