The Dynamic Nature of Ecosystems

The author presents the argument that it is the trade-off between the irregular, chaotic dynamics at the level of populations and the spatio-temporal organization at the level of the system as a whole that shapes ecological systems. This book combines the topics of theoretical analysis, natural science, philosophy and fundamental ecology in a synthetic treatment. Outlines a coherent framework to delineate the internal structure of ecological networks along the dimensions of time, space and function in the network context. Introduces mathematical tools to describe and quantify the functional importance of spatial and temporal patterns in ecological networks for ecosystem organization. Setting the Stage.

Claudia Pahl-Wostl is the author of The Dynamic Nature of Ecosystems: Chaos and Order Entwined , published by Wiley. The Dynamic Nature of Ecosystems Chaos and Order Entwined Claudia Pahl-Wostl Swiss Federal Institute of Technology (ETH), Zürich, Switzerland and Swiss Federal Institute for Environmental Science and Technology (EAWAG), Dübendorf, Switzerland How do ecosystems combine function and adaptability despite comprising large ensembles of individual populations that are not subject to any central control? This question is addressed in The Dynamic Nature of Ecosystems by replacing the prevailing static view of the balance of nature with a more dynamic perspective. It argues that it is the trade-off between the irregular, chaotic dynamics at the population level and the spatio-temporal organization of the system as a whole, that shapes ecological systems. Such a trade-off is mediated by the effects of positive feedback that link populations across time and space. By rejecting a purely mechanistic perception, this volume sets out to develop a new framework within which the dynamic nature and organization of ecosystems can be understood. Such a perspective leads to emphasizing uncertainty as an essential part of ecological systems instead of viewing it as an obstacle impeding quantitative evaluations and predictions. It is suggested in the book that it may be impossible to consider this issue solely from within the natural sciences, and indeed a collaborative effort by empirical and theoretical ecologists, resource managers, and social scientists may be needed in order to develop adequate concepts along these lines of reasoning, for tackling the pressing environmental problems facing humankind today.
