Trama

Landscape Ecology is a rapidly growing science of quantifying the ways in which ecosystems interact and or establish links between activities in one region and repercussions in another. This book, which will serve as a general introduction to this relatively new and emerging area of study, takes what the authors call a "top-down approach" i.e., believing that context is equally as important as content and that an isolated, dismembered landscape fragment will lose biodiversity. This is in contrast to past and current ecosystem studies which have not focused on outside influences. The authors argue that the most detailed mathematical models of all the biodiversity within a landscape will not suffice to predict the outcome of management practices if the contextual analysis reveals that human impacts outside the landscape are contributing to a reserve's ultimate demise. The authors will demonstrate, via the material presented in this book, that protecting disconnected vignettes of nature in isolated national parks and reserves or saving so-called "hot-spots" of biodiversity simply will not work.




Note Editore

Landscape Ecology - a rapidly growing science - quantifies the ways ecosystems interact. It establishes links between activities in one region and repercussions in another. Landscape Ecology: A Top-Down Approach serves as a general introduction to this emerging area of study.In this book the authors take a "top down" approach. They believe that context is equally as important as content and that an isolated, dismembered landscape fragment loses biodiversity. In contrast, past and current ecosystem studies have not considered the consequences of outside influences.The authors argue that the most detailed mathematical models of biodiversity within a landscape do not suffice to predict the outcome of management practices if the contextual analysis reveals that human impacts outside the landscape contribute to a reserve's ultimate demise. The material presented in this book demonstrates that protecting disconnected vignettes of nature in isolated national parks and reserves, or saving so-called "hot spots" of biodiversity, does not work.The rapid convergence of themes in ecology supports the study of the ecology of landscapes. Advances in this field will come from studies in landscape effects and the mobile organisms whose top down effects create and maintain landscapes. Landscape Ecology: A Top Down Approach supplies the basics for this work.
