Available in PDF, EPUB and Kindle. Book excerpt: We live in a changing world; one in which there is much concern and discussion about the topics of global change, loss of biodiversity, and increasing threats to the sustainability of ecosystems. The effects these changes may have on the environment have lead governments and sCientists to make predictions as to how soon changes might occur, where, and with what impact for large and small regions of the Earth. Along with this concern for change in various regions has come the need to understand the role of boundaries between these regions and between landscape elements. Much previous ecological research has dealt with processes within relatively homogeneous landscape units or even the collective characteristics of a composite landscape. Now, however, there is an appreciation that abiotic and biotic components move across heterogeneous landscapes and that the boundaries between these units take on important control functions in this dynamic spatial system. Furthermore, landscape boundaries (or ecotones) are important not only in satisfying life-cycle needs of many organisms, but generally are characterized by high biological diversity.

Download or read book Ecotones Between Forest and Grassland written by Randall W. Myster and published by Springer Science & Business Media. This book was released on 2012-07-10 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecotones are dynamic over-lapping boundary areas where major terrestrial biomes meet. As past studies have shown, and as the chapters in this book will illustrate, their structure, size, and scope have changed considerably over the millennia, expanding and shrinking as climate and/or other driving conditions, also changed. Today, however, many of them are changing at a rate not seen for a long time, perhaps largely due to climate change and other human-induced factors. Indeed ecotones are more sensitive to climate change than the biomes on either side, and thus may serve as critical early indicators of future climate change. As ecotones change, they also redefine the limits of the biomes on either side by altering their distributions of species because, in addition to their own endemic species, any ecotone will also have species from both adjoining biomes. Consequently, they may also be places of high levels of species interaction, serving as active evolutionary laboratories, which generate new species that then migrate back into adjacent biomes. Ecotones Between Forest and Grassland explores how these ecotones have changed in the past, how they are changing today, and how they are likely to change in the future. The book includes chapters from around the world with a special focus on South American and Neotropical ecotones.
Download or read book The Importance of Aquatic Terrestrial Ecotones for Freshwater Fish written by F. Schiemer and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecotones are interface zones between different ecosystems. Their ecological role and significance with regard to ecological management and conservation has become increasingly appreciated. For the management of freshwater resources, for example, an improved understanding of the role of land/inland water interfaces, will be essential for reducing negative human impacts by engineering, nutrient loading, siltation, etc. The management of ecotones, on the other hand, offers the possibility to control aquatic system processes via stock control of fish populations. Fish apparently are both excellent indicators of ecotone quality as well as determiners of its structure and function.
Download or read book Landscape Boundaries written by Andrew J. Hansen and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 462 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Ecology of Himalayan Treeline Ecotone written by S P Singh and published by Springer Nature. This book was released on 2023-02-21 with total page 575 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book brings together comprehensive multi-disciplinary knowledge on diverse aspects of the Himalayan treeline ecotone which is considered one of the most sensitive ecosystems to climate change. The contents of this book are based on the results of extensive research and provide a holistic understanding of the treeline ecotone in Himalaya. The book will serve as an important reference manual and a textbook on treeline ecology. The book is unique in the sense that it provides an engaging account of almost all the aspects of the treeline ecotone, such as taxonomic, functional and phylogenetic species diversity, temperature lapse rates, tree phenology, water relations, and stress physiology, tree ring width chronology, and climate relationships and the role of treeline ecotone in human sustenance in the Indian Himalayan region The treelines in the Himalaya, being the highest in the Northern Hemisphere (up to 4900 m), are among the least investigated systems and hence this book is timely and fills all-important knowledge gaps vis-à-vis treeline shifts, physiognomic, structural, and functional changes in mountain landscapes and ecosystems, particularly under the changing climate This book, for the first time, summarizes evidence-based knowledge about various aspects of treeline ecotone in Himalaya that was largely generated through a well-coordinated a team science approach. The book will be of interest to ecologists, climatologists, dendrochronologists, foresters, plant physiologists and resource managers and policy planners for a better understanding of the organization and dynamics of this fragile ecosystem in relation to climate change and other anthropogenic stresses that are rampant in the Himalaya. The book lays a solid foundation for further investigation of the ecology and dynamics of the treeline ecotone in the Himalayas and provides a rationale for pursuing a team science approach for macroecological investigations.

Summing Up: Recommended. Undergraduates and general readers." —CHOICE Booklist Editors′ Choice 2008 "This superb interdisciplinary work should find a place on the shelves of every public and academic library that has the least bit of interest in environment issues—which should mean just about all." —Booklist (Starred Review) Where does the environment leave off and society begin? When expanding production and consumption drives greenhouse gas emissions that warm the planet, which in turn influence the conditions of economic expansion, it is unclear where the climate ends and the economy begins. This fact is not new to our era, however, our social and natural sciences have only recently come to grips with the incredible complexity of the world described by understanding the environment and society as being of a piece. As a result, in the last decade there has been an unprecedented explosion of new concepts, theories, facts, and techniques that follow from such an understanding. The Encyclopedia of Environment and Society brings together multiplying issues, concepts, theories, examples, problems, and policies, with the goal of clearly explicating an emerging way of thinking about people and nature. With more than 1,200 entries written by experts from incredibly diverse fields, this innovative resource is a first step toward diving into the deep pool of emerging knowledge. The five volumes of this Encyclopedia represent more than a catalogue of terms. Rather, they capture the spirit of the moment, a fascinating time when global warming and genetic engineering represent only two of the most obvious examples of socio-environmental issues. Key Features Examines many new ideas about how the world works, what creates the daunting problems of our time, and how such issues might be addressed, whether by regulation, markets, or new ethics Demonstrates how theories of environmental management based on market efficiency may not be easily reconciled with those that focus on population, and both may certainly diverge from those centering on ethics, justice, or labor Offers contributions from experts in their fields of specialty, including geographers, political scientists, chemists, anthropologists, medical practitioners, development experts, and sociologists, among many others Explores the emerging socio-environmental problems that we face in the next century, as well as the shifting and expanding theoretical tools available for tackling these problems Covers regions of North America in greater detail but also provides a comprehensive picture that approaches, as effectively as possible, a cohesive global vision Key Themes Agriculture Animals Biology and Chemistry Climate Conservation and Ecology Countries Geography History Movements and Regulations Organizations People Politics Pollution Society Packed with essential and up-to-date information on the state of the global socio-environment, the Encyclopedia of Environment and Society is a time capsule of its historic moment and a record of where we stand at the start of the 21st century, making it a must-have resource for any library. These inspiring volumes provide an opportunity for more new ways of thinking, behaving, and living in a more-than-human world.
Download or read book Tropical Forest Remnants written by William F. Laurance and published by University of Chicago Press. This book was released on 1997-06-21 with total page 646 pages. Available in PDF, EPUB and Kindle. Book excerpt: We live in an increasingly fragmented world, with islands of natural habitat cast adrift in a sea of cleared, burned, logged, polluted, and otherwise altered lands. Nowhere are fragmentation and its devastating effects more evident than in the tropical forests. By the year 2000, more than half of these forests will have been cut, causing increased soil erosion, watershed destabilization, climate degradation, and extinction of as many as 600,000 species. Tropical Forest Remnants provides the best information available to help us understand, manage, and conserve the remaining fragments. Covering geographic areas from Southeast Asia and Australia to Madagascar and the New World, this volume summarizes what is known about the ecology, management, restoration, socioeconomics, and conservation of fragmented forests. Thirty-three papers present results of recent research as well as updates from decades-long projects in progress. Two final chapters synthesize the state of research on tropical forest fragmentation and identify key priorities for future work.
Download or read book Long Term Ecological Research written by Felix Müller and published by Springer Science & Business Media. This book was released on 2010-06-21 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecosystems change on a multitude of spatial and temporal scales. While analyses of ecosystem dynamics in short timespans have received much attention, the impacts of changes in the long term have, to a great extent, been neglected, provoking a lack of information and methodological know-how in this area. This book fills this gap by focusing on studies dealing with the investigation of complex, long-term ecological processes with regard to global change, the development of early warning systems, and the acquisition of a scientific basis for strategic conservation management and the sustainable use of ecosystems. Within this book, theoretical ecological questions of long-term processes, as well as an international dimension of long-term monitoring, observations and research are brought together. The outcome is an overview on different aspects of long-term ecological research. Aquatic, as well as terrestrial ecosystems are represented.
Download or read book Nutrient Dynamics and Retention in Land Water Ecotones of Lowland Temperate Lakes and Rivers written by A. Hillbricht-Ilkowska and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecotones, or boundary zones between land and inland waters (such as lakes, streams and rivers), are the principal routes for transport of organic matter and nutrients across landscapes via physical and biological vectors. The ecotone is the place of cumulation and transformation of in situ production as well as of allochthonous material from adjacent aquatic and terrestrial systems. The ecotype functions as an important barrier or filter for principal nutrients, such as phosphorus and nitrogen, responsible for the eutrophication and degradation of surface waters. Intensive forest cutting, agriculture, pollution and bank regulation, urbanization and hydrotechnical constructions seriously endanger the ecotone systems and damage their protective function. It is vital to develop a scientific understanding of the behaviour of phosphorus and nitrogen in these transitional boundary habitats. Such an understanding is important for the rational protection, management and restoration of ecotones connected with lakes and rivers. The importance of nutrient cycling and retention is discussed from the point of view of ecotone function, management and reconstruction in order to sustain its protective role for water bodies. Various types of land/water transitory zones are discussed: wetlands, lake littoral systems, riparian zones of rivers, streams and brooks, the contact zones between groundwater and surface waters of lakes and rivers, air--water interfaces, and patch/ecotone structures in watersheds.
Download or read book Ecohydrology Hydrobiology written by and published by . This book was released on 2001 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: The international journal Ecohydrology & Hydrobiology (E&H) has been created to promote the concept of Ecohydrology, which is defined as the study of the functional interrelations between hydrology and biota at the catchment scale. Ecohydrology extends from the molecular level to catchment-scale processes and is based on three principles: • framework (hydrological principle) - quantification and integration of hydrological and ecological processes at a basin scale; • target (ecological principle) - necessity of enhancing ecosystem absorbing capacity and ecosystem services; and • management tool (ecological engineering) – the use of ecosystem properties for regulation the interplay between hydrology and biota. The journal encourages the submission of manuscripts which adopt an integrative approach to aquatic sciences, explaining ecological and hydrological processes at a river-basin scale or propose practical applications of this knowledge. It will also consider papers in other hydrobiological fields. Especially welcome are papers on regulatory mechanism within biocenosis and the resistance and resilience of freshwater and costal zones ecosystems. There is no page charge for published papers. All submitted papers, written exclusively in English, should be original works, unpublished and not under consideration for publication elsewhere. All papers are peer-reviewed. The following types of papers are considered for publication in E&H: • original research papers • invited or submitted review papers, • short communications
Download or read book Principles and Methods in Landscape Ecology written by Almo Farina and published by Springer Nature. This book was released on 2022-05-25 with total page 457 pages. Available in PDF, EPUB and Kindle. Book excerpt: This third, thoroughly updated edition of a well received book, presents the most complete collection of theories, paradigms and methods utilized by the landscape sciences. With the introduction of new ecosemiotic concepts and innovative managing procedures, it offers a broad list of ecological, ecosemiotical and cultural tools to investigate, interpret and manage the environmental complexity according to a species-specific individual-based approach. Readers will discover the importance of a landscape perspective to create strategic bridges between science and humanities favored by the holistic sight of sensorial (visual, acoustic, olfactory, tactile, and thermal) “scapes”. Distributed in 10 chapters, the content covers many aspects of the landscape sciences ranging from the description of fundamental theories, principles and models originated by ecological approaches like source-sink models, island biogeography, hierarchical theory and scale. The ecosemiotical approaches like the eco-field model, the ecoscape paradigm, and the general theory of resources are widely described and discussed. A cultural approach to landscape is utilized to focus on the heritage values of territories and their environmental identity. This book, written in an accessible and didactic style, is particularly dedicated to undergraduate and graduate students but also scholars in ecology, agroforestry, urban planning, nature design, conservation and remediation. Land practitioners, farmers and policymakers can use this book as an authoritative guide to better understand the function and role of environmental systems according to a social-economic integrated perspective.

Download or read book Environmental Information Management And Analysis written by W K Michener and published by CRC Press. This book was released on 1994-08-08 with total page 574 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most environmental studies are based upon data collected at fine spatial scales plots, sediments, cores, etc.. Furthermore, temporal scales of these studies have been relatively short days, weeks, months and few studies have exceeded three years duration the typical funding cycle.; Despite this history, environmental scientists are now being called upon to extrapolate findings from "plot-level" studies to broader spatial scales and from short-term studies to longer temporal scales, up to decades for questions related to long-term processes such as global warming and the rise in sea level.; The complex questions being addressed internationally require that scientists take advantage of new technologies including remote sensing, geographic information systems GIS, and powerful climatic and environmental simulation models. As more environmental scientists begin to work at these broader spatial and temporal scales, and to utilize many of the newer technologies, they are recognising a whole new class of problems.; This book aims to address the most pertinent issues, and includes a comprehensive review of selected topics, case studies, and theoretical discussions, divided into seven sections each preceded by a brief introduction.
