Linkages in the Landscape by Andrew F. Bennett Pdf
The loss and fragmentation of natural habitats is one of the major issues in wildlife management and conservation. Habitat "corridors" are sometimes proposed as an important element within a conservation strategy. Examples are given of corridors both as pathways and as habitats in their own right. Includes detailed reviews of principles relevant to the design and management of corridors, their place in regional approaches to conservation planning, and recommendations for research and management.
Until well into recent times, a high level of connectivity existed among ecosystems. Through the ever-increasing extent and intensity of human exploitation of natural resources, however, the pattern of human activities as islands in a sea of nature has become reversed in most of the world's regions. Habitat fragmentation is now one of the most important causes of the decline in biodiversity. The main purpose of this review is to assist the understanding of the practical value of maintaining, enhancing, creating or restoring linkages.
Landscape Linkages and Biodiversity by Lisa Defenders of Wildlife Pdf
In Landscape Linkages and Biodiversity experts explain biological diversity conservation, focusing on the need for protecting large areas of the most diverse ecosystems, and connecting those ecosystems with land corridors to allow species to move among them more easily.

Applying Landscape Ecology in Biological Conservation by Kevin Gutzwiller Pdf
This book provides a current synthesis of principles and applications in landscape ecology and conservation biology. Bringing together insights from leaders in landscape ecology and conservation biology, it explains how principles of landscape ecology can help us understand, manage and maintain biodiversity. Gutzwiller also identifies gaps in current knowledge and provides research approaches to fill those voids.
Landscape Boundaries by Andrew J. Hansen,Francesco DiCastri Pdf
The emergence of landscape ecology during the 1980s represents an impor tant maturation of ecological theory. Once enamored with the conceptual beauty of well-balanced, homogeneous ecosystems, ecologists now assert that much of the essence of ecological systems lies in their lumpiness. Patches with differing properties and behaviors lie strewn across the land scape, products of the complex interactions of climate, disturbance, and biotic processes. It is the collective behavior of this patchwork of eco systems that drives pattern and process of the landscape. is not an end point This realization of the importance of patch dynamics in itself, however. Rather, it is a passage to a new conceptual framework, the internal workings of which remain obscure. The next tier of questions includes: What are the fundamental pieces that compose a landscape? How are these pieces bounded? To what extent do these boundaries influence communication and interaction among patches of the landscape? Will con sideration of the interactions among landscape elements help us to under stand the workings of landscapes? At the core of these questions lies the notion of the ecotone, a term with a lineage that even predates ecosystem. Late in the nineteenth century, F. E. Clements realized that the transition zones between plant communi ties had properties distinct from either of the adjacent communities. Not until the emergence of patch dynamics theory, however, has central signif icance of the ecotone concept become apparent.
Landscapes, Identities and Development by Zoran Roca,Paul Claval,John Agnew Pdf
Bringing together theoretical and empirical research from 22 countries in Europe, North America, Australia, South America and Japan, this book offers a state-of-the-art survey of conceptual and methodological research and planning issues relating to landscape, heritage, [and] development. It has 30 chapters grouped in four main thematic sections: landscapes as a constitutive dimension of territorial identities; landscape history and landscape heritage; landscapes as development assets and resources; and landscape research and development planning. The contributors are scholars from a wide range of cultural and professional backgrounds, experienced in fundamental and applied research, planning and policy design. They were invited by the co-editors to write chapters for this book on the basis of the theoretical frameworks, case-study research findings and related policy concerns they presented at the 23rd Session of PECSRL - The Permanent European Conference for the Study of the Rural Landscape, organized by TERCUD - Territory, Culture and Development Research Centre, Universidade Lusófona, in Lisbon and Óbidos, Portugal, 1 - 5 September 2008. With such broad inter-disciplinary relevance and international scope, this book provides a valuable overview, highlighting recent findings and interpretations on historical, current and prospective linkages between changing landscapes and natural, economic, cultural and other identity features of places and regions; landscape-related identities as local and regional development assets and resources in the era of globalized economy and culture; the role of landscape history and heritage as platforms of landscape research and management in European contexts, including the implementation of The European Landscape Convention; and, the strengthening of the landscape perspective as a constitutive element of sustainable development.
Basic Landscape Ecology by Robert Norris Coulson,Maria D. Tchakerian Pdf
Basic Landscape Ecology is intended to be a starting point for the study of landscape ecology. The goal is to provide a contemporary synthesis of basic landscape ecological concepts with an applied interpretation. The text is divided into two sections. The first section, which consists of six chapters, is intended to provide a uniform background for students from various academic disciplines. The second section, which consists of four chapters, is intended to provide an examination of the substance of contemporary landscape ecology.
Connectivity Conservation by Kevin R. Crooks,M. Sanjayan Pdf
One of the biggest threats to the survival of many plant and animal species is the destruction or fragmentation of their natural habitats. The conservation of landscape connections, where animals, plants, and ecological processes can move freely from one habitat to another, is therefore an essential part of any new conservation or environmental protection plan. In practice, however, maintaining, creating, and protecting connectivity in our increasingly dissected world is a daunting challenge. This fascinating volume provides a synthesis on the current status and literature of connectivity conservation research and implementation. It shows the challenges involved in applying existing knowledge to real-world examples and highlights areas in need of further study. Containing contributions from leading scientists and practitioners, this topical and thought-provoking volume will be essential reading for graduate students, researchers, and practitioners working in conservation biology and natural resource management.
Essentials of Landscape Ecology by Kimberly A. With Pdf
Human activity during the Anthropocene has transformed landscapes worldwide on a scale that rivals or exceeds even the largest of natural forces. Landscape ecology has emerged as a science to investigate the interactions between natural and anthropogenic landscapes and ecological processes across a wide range of scales and systems: from the effects of habitat or resource distributions on the individual movements, gene flow, and population dynamics of plants and animals; to the human alteration of landscapes affecting the structure of biological communities and the functioning of entire ecosystems; to the sustainable management of natural resources and the ecosystem goods and services upon which society depends. This novel and comprehensive text presents the principles, theory, methods, and applications of landscape ecology in an engaging and accessible format that is supplemented by numerous examples and case studies from a variety of systems, including freshwater and marine "scapes".
Designing Greenways by Paul Cawood Hellmund,Daniel Smith Pdf
How are greenways designed? What situations lead to their genesis, and what examples best illustrate their potential for enhancing communities and the environment? Designing greenways is a key to protecting landscapes, allowing wildlife to move freely, and finding appropriate ways to bring people into nature. This book brings together examples from ecology, conservation biology, aquatic ecology, and recreation design to illustrate how greenways function and add value to ecosystems and human communities alike. Encompassing everything from urban trail corridors to river floodplains to wilderness-like linkages, greenways preserve or improve the integrity of the landscape, not only by stemming the loss of natural features, but also by engendering new natural and social functions. From 19th-century parks and parkways to projects still on the drawing boards, Designing Greenways is a fascinating introduction to the possibilities-and pitfalls-involved in these ambitious projects. As towns and cities look to greenways as a new way of reconciling man and nature, designers and planners will look to Designing Greenways as an invaluable compendium of best practices.
Mosaic Landscapes and Ecological Processes by L. Hansson,L. Fahrig,G. Merriam Pdf
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.
Landscape Dynamics, Soils and Hydrological Processes in Varied Climates by Assefa M. Melesse,Wossenu Abtew Pdf
The book presents the processes governing the dynamics of landscapes, soils and sediments, water and energy under different climatic regions using studies conducted in varied climatic zones including arid, semi-arid, humid and wet regions. The spatiotemporal availability of the processes and fluxes and their linkage to the environment, land, soil and water management are presented at various scales. Spatial scales including laboratory, field, watershed, river basin and regions are represented. The effect of tillage operations and land management on soil physical characteristics and soil moisture is discussed. The book has 35 chapters in seven sections: 1) Landscape and Land Cover Dynamics, 2) Rainfall-Runoff Processes, 3) Floods and Hydrological Processes 4) Groundwater Flow and Aquifer Management, 5) Sediment Dynamics and Soil Management, 6) Climate change impact on vegetation, sediment and water dynamics, and 7) Water and Watershed Management.
How Landscapes Change by Gay A. Bradshaw,Pablo Marquet Pdf
North and South America share similar human and ecological histories and, increasingly, economic and social linkages. As such, issues of ecosystem functions and disruptions form a common thread among these cultures. This volume synthesizes the perspectives of several disciplines, such as ecology, anthropology, economy, and conservation biology. The chief goal is to gain an understanding of how human and ecological processes interact to affect ecosystem functions and species in the Americas. Throughout the text the emphasis is placed on habitat fragmentation. At the same time, the book provides an overview of current theory, methods, and approaches used in the analysis of ecosystem disruptions and fragmentation.
