Beschreibungen

This groundbreaking work connects the knowledge of system function developed in ecosystem ecology with landscape ecology's knowledge of spatial structure. The book elucidates the challenges faced by ecosystem scientists working in spatially heterogeneous systems, relevant conceptual approaches used in other disciplines and in different ecosystem types, and the importance of spatial heterogeneity in conservation resource management.
Among the most dif?cult problems in the life sciences is the challenge to understand the details of how ecosystems/watersheds/landscapes function. Yet,the welfare of all life,not just the human species,depends upon the s- cessful functioning of diverse and complicated ecosystems, each with va- ous dimensions and compositions. Central to this “working” is the dominance, and to a major extent control, of ecosystems by organisms, which means that these systems are constantly changing as the component organisms change and evolve. Such changes increase the challenge to understand the functioning of ecosystems and landscapes. Moreover,und- standing the interactions among the myriad components of these systems is mind-boggling as there are scores of biotic (probably many thousands of species when the microbial components are fully enumerated through genomics) and countless abiotic (ions, molecules, and compounds) entities, all simultaneously interacting and responding to diverse external factors to produce functional or dysfunctional environments for life. This book focuses on the problems of connectedness and ecosystem fu- tioning. It is dif?cult enough to understand how an ecosystem functions when it is considered in isolation, but all ecosystems are open and c- nected to everything else. Clearly, the inputs to any ecosystem are the o- puts from others and vice versa, and as such the ?uxes represent major, if not critical, points for managing or changing the overall functioning of an ecosystem or landscape. A major challenge is to ?nd appropriate conceptual frameworks to address these complicated problems.

The study of ecosystems, fundamental to ecology, has been complemented by the growing field of landscape ecology.  Ecosystem Function in Heterogeneous Landscapes addresses how interactions among ecosystems affect the functioning of individual ecosystems and the larger landscape.  This groundbreaking synthesis unites ecosystem ecology's knowledge of system function with landscape ecology's knowledge of spatial structure. 
Practical concerns about scaling up from individual ecosystems to larger landscapes require an understanding of how networks of interacting ecosystems function together.  The book elucidates the challenges faced by ecosystem scientists working in spatially heterogeneous systems, relevant conceptual approaches used in other disciplines and in different ecosystem types, and the importance of spatial heterogeneity in conservation resource management.  The distinguished authors discuss how how much heterogeneity needs to be taken into account for specific types of scientific and management issues.  Their chapters cover the spectrum from proposing novel conceptual approaches to detailing the practical implications of heterogeneous landscapes for fire management, water management and conservation planning.
No comparable book exists. Contributing authors provide overviews of specific disciplines, while several prominent scientists write synthesis chapters which help the reader draw connections between the fields of landscape ecology and ecosystem ecology
