Landscape Ecology of a Stressed Environment

This series presents studies that have used the paradigm of landscape ecology. Other approaches, both to landscape and landscape ecology are common, but in the last decade landscape ecology has become distinct from its predecessors and its contemporaries.

This series presents studies that have used the paradigm of landscape ecology. Other approaches, both to landscape and landscape ecology are common, but in the last decade landscape ecology has become distinct from its predecessors and its contemporaries. Landscape ecol­ ogy addresses the relationships among spatial patterns, temporal pat­ terns and ecological processes. The effect of spatial configurations on ecological processes is fundamental. When human activity is an import­ ant variable affecting those relationships, landscape ecology includes it. Spatial and temporal scales are as large as needed for comprehension of system processes and the mosaic included may be very heteroge­ neous. Intellectual utility and applicability of results are valued equally. The International Association for Landscape Ecology sponsors this series of studies in order to introduce and disseminate some of the new knowledge that is being produced by this exciting new environmental science. Gray Merriam Ottawa, Canada Preface In Europe, during the seventies, landscape ecology emerged as a fusion of the spatial approach of geographers and the functional approach of ecologists. The latter focused on ecosystem functioning, regarding eco­ systems as homogeneous, almost abstract units in space, with input and output of energy and matter to and from the undefined surroundings.
