Description :

With the accelerating loss of biodiversity there is increasing concern about how this loss may be affecting ecosystem processes that are of benefit to human well-being. The limited studies that address the principal question directly, species numbers versus system function, are evaluated. Moreover, the degree of redundancy within systems, the ubiquity of keystone species, the tightness of species interactions from mutualism to food webs, the resilience of systems to perturbation, and the interactions of landscape units are explored, as are how policy decisions are made in this research area, this volume brings together in a substantive and integrative manner the disciplines of population biology and ecosystem science, both directed toward evaluating the consequences of anthropogenic disruptions of natural systems.
