Agents and Implications of Landscape Pattern (eBook, PDF)

Working Models for Landscape Ecology

• Format: PDF

Produktbeschreibung

This is an ecology textbook focused on key principles that underpin research and management at the landscape scale. It covers (1) agents of pattern (the physical template, biotic processes, and disturbance regimes); (2) scale and pattern (why scale matters, how to 'scale' with data, and inferences using landscape pattern metrics); and (3) implications of pattern (for metapopulations, communities and biodiversity, and ecosystem processes). The last two chapters address emerging issues: urban landscapes, and adapting to climate change.

This book stems from two graduate-level courses in Landscape Ecology taught at the Nicholas School of the Environment at Duke University. The subject has evolved over time, from a concepts-based overview of what landscape ecology is, to a more applied practicum on how one does landscape ecology. As landscape ecology has matured as a discipline, its perspectives on spatial heterogeneity and scale have begun topermeate into a wide range of other fields including conservation biology, ecosystem management, and ecological restoration. Thus, this textbook will bring students from diverse backgrounds to a common level of understanding and will prepare them with the practical knowledge for a career in conservation and ecosystem management.

Autorenporträt

Dean Urban is Professor of Landscape Ecology in the Nicholas School of the Environment at Duke University. His research focuses on devising innovative and rigorous approaches to applications of immediate practical concern. His research tools include habitat classification and mapping, site prioritization, spatial simulation, and integrated assessment. A hallmark of his work is integrated studies that extrapolate our fine-scale empirical understanding of environmental issues to the larger space and time scales of management and policy. Most of his work in landscape ecology has explored the causes and consequences of spatial pattern in forest systems. Specific interests include the implications of climate change for forest ecosystems, and the consequences of land use pattern on forest habitat connectivity and watershed function in developed landscapes. His current research focus is how land use affects the provision of ecosystem services, and in reconciling human institutions with natural systems.
