Book Description
The effects of isolation, area size, and habitat quality on the survival of animal and plant populations in the cultural landscape are central aspects of a research project started in Germany in 1993 (,Forschungsverbund, Isolation, FHichengroBe und BiotopquaIiHit', abbreviated to 'FIFB'). After a long period of preparation, scientists from seven univer sities and one research institution started to work within the frame of this project. Fund ing for four years was provided by the former German Federal Ministry of Research and Technology (BMFT), now the Ministry of Education and Research (BMBF). A strong focus of the project has been the improvement of the methodology for environmental impact assessments and the implementation of results into environmental planning. As there is a certain risk that national projects develop some kind of 'mental in breeding', it was decided to discuss concepts, methods, and first results with scientists of international reputation at a rather early stage of the project. For this purpose, an inter national workshop was held in the small village of Lubast, north of Leipzig (state of Saxony) in March 1995. 130 scientists from 10 nations met to discuss and debate issues surrounding habitat fragmentation for three days. Papers presented there formed the basis for this book. As discussions included general reviews as well as particular case studies, we decided to structure this book in a similar way. Consequently, a combination of broad and more general, review-like papers as well as original papers are presented.

Book Description
Mark W. Schwartz Soon after we came into extensive meadows: and I was assured that those meadows continue for a hundred and fifty miles. being in winter drowned lands and marshes. By the dryness of the season they were now beautiful pastures, and here presented itself one of the most delightful prospects I have ever beheld; all low grounds being meadow, and without wood, and all of the high grounds being covered with trees and appearing like islands: the whole scene seemed an elysium. Capt. Thomas Morris. 1791 I am sitting in a 60-mile-an-hour bus sailing over a highway originally laid out for horse and buggy. The ribbon of concrete has been widened and widened until the field fences threaten to topple into the road cuts. In the narrow thread of sod between the shaved banks and the toppling fences grow the relics of what once was Illinois: the prairie.

Ecology of Fragmented Landscapes

Category : Nature
Languages : en
Pages : 358

Book Description
Ask airline passengers what they see as they gaze out the window, and they will describe a fragmented landscape: a patchwork of desert, woodlands, farmlands, and developed neighborhoods. Once-contiguous forests are now subdivided; tallgrass prairies that extended for thousands of miles are now crisscrossed by highways and byways. Whether the result of naturally occurring environmental changes or the product of seemingly unchecked human development, fractured lands significantly impact the planet’s biological diversity. In Ecology of Fragmented Landscapes, Sharon K. Collinge defines fragmentation, explains its various causes, and suggests ways that we can put our lands back together. Researchers have been studying the ecological effects of dismantling nature for decades. In this book, Collinge evaluates this body of research, expertly synthesizing all that is known about the ecology of fragmented landscapes. Expanding on the traditional coverage of this topic, Collinge also discusses disease ecology, restoration, conservation, and planning. Not since Richard T. T. Forman's classic Land Mosaics has there been a more comprehensive examination of landscape fragmentation. Ecology of Fragmented Landscapes is critical reading for ecologists, conservation biologists, and students alike.

Pasture Landscapes and Nature Conservation

Pasture Landscapes and Nature Conservation PDF Author: Bernd Redecker

Pages : 443

Book Description
One of the main problems and aims of nature conservation in Europe is to protect semi-open landscapes. The development during the past decades is characterized by an ongoing intensivation of land use on the one hand, and an increasing number of former meadows and pastures lying fallow caused by changing economic conditions on the other hand. In several countries the estabishment of larger "pasture landscapes" with a mixed character of open grassland combined with shrubs and forests has been recognized as one solution to this problem. The book gives an overview of the European projects concerning to this topic - nature conservation policy and strategies, scientific results and practical experiences creating large scale grazing systems.

Landscape Ecology of a Stressed Environment

Landscape Ecology of a Stressed Environment PDF Author: Claire C. Vos
Publisher: Springer Science & Business Media
ISBN: 9401123187
Category : Science
Languages : en
Pages : 310

Book Description
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.

Book Description
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.

How Landscapes Change

How Landscapes Change PDF Author: Gay A. Bradshaw
Publisher: Springer Science & Business Media
ISBN: 3662052385
Category : Science
Languages : en
Pages : 373

Book Description
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.

Conservation Medicine

Conservation Medicine PDF Author: A. Alonso Aguirre
Publisher: Oxford University Press
ISBN: 0195348621
Category : Medical
Languages : en
Pages : 432

Book Description
Conservation medicine is an emerging discipline, focussing on the intersection of ecosystem health, animal health, and human health. Work in the biomedical and veterinary sciences is now being folded into conservation biology; to explore the connections between animal and human health; trace the environmental sources of pathogens and pollutants; develop an understanding of the ecological causes of changes in human and animal health; and understand the consequences of diseases to populations and ecological communities. Conservation Medicine defines this new discipline. It examines ecological health issues from various standpoints, including the emergence and resurgence of infectious disease agents; the increasing impacts of toxic chemicals and hazardous substances; and the health implications of habitat fragmentation and degradation and loss of biodiversity. It will provide a framework to examine the connections between the health of the planet and the health of all species and challenge practitioners and students in the health sciences and natural sciences to think about new, collaborative ways to address ecological health concerns.
