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 ecology addresses the relationships among spatial patterns, temporal patterns and ecological processes. The effect of spatial configurations on ecological processes is fundamental. When human activity is an important 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 heterogeneous. Intellec tual utility and applicability of results are valued equally. The Inter national 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 Foreword This is a book about real nature, or as close to real as we know - a nature of heterogeneous landscapes, wild and humanized, fine-grained and coarse-grained, wet and dry, hilly and flat, temperate and not so temper ate. Real nature is never uniform. At whatever spatial scale we examine nature, we encounter patchiness. If we were to look down from high above at a landscape of millions of hectares, using a zoom lens to move in and out from broad overview to detailed inspection of a square meter we would see that patterns visible at different scales overlay one another.

1 Landscape mosaics and ecological theory.- 1.1 Introduction.- 1.2 The role of theory in ecology.- 1.3 How have ecologists viewed space?.- 1.4 How have ecologists dealt with spatial mosaics?.- 1.5 Developing theory in landscape ecology.- One Origin of Landscape Pattern.- 2 Spatial and temporal landscape patterns in arid and semi-arid African savannas.- 3 Effects of animals on landscape pattern.- Two Response of Individuals and Populations to Landscape Pattern.- 4 Movement patterns related to spatial structures.- 5 Habitat selection in mosaic landscapes.- 6 Resource tracking in space and time.- Three Landscape Pattern, Population Dynamics and Population Genetics.- 7 Landscape structure and genetic variation in plants: empirical evidence.- 8 Effects of population dynamics on genetics in mosaic landscapes.- Four Effects of Landscape Pattern on Species Interactions.- 9 Effects of landscape pattern on competitive interactions.- 10 Effects of landscape composition on prédation rates at habitat edges.- 11 The plant-pollinator landscape.- Five Implications for Conservation.- 12 Landscape pattern and population conservation.- 13 Incorporating landscape pattern into conservation programs.- Summary - Ecology of Mosaic Landscapes: Consolidation, Extension and Application.

The examination of the most recent studies including more than one habitat and interactions between habitats, plus the significance of this approach for generalizations to other ecological mechanisms, is the subject of this important book. Mosaic Landscapes and Ecological Processes will help ecologists and conservation biologists to solve real-life problems. - Ethology, Ecology & Evolution; ...I found Mosaics Landscapes a pleasure to read...the entire enterprise comes together splendidly, offering for the first time an appreciation of the 'organism eye-view' of landscape ecology...Mosaic Landscapes offers a 'state of the art' discussion of the ecological theory... - Trends in Ecology and Evolution
