Is ecological knowledge relevant to environmental policy and if so, to what extent and in what way? After a series of oxygen depletion events in coastal waters in the 1980s, North Sea states acted to reduce inputs of nitrogen and phosphorus to the North Sea. The book analyzes the role of scientists and scientific information, as well as civil servants, in the formulation and implementation of these decisions.
Riverbank filtration is widely used in Europe and to some extent in
the United States for the public water supply. It is a
cost-effective and realisable treatment technology in which
horizontal and vertical wells pump a mixture of ground water and
induced surface water from a river. This book describes the
biogeochemical issues involved in contaminant removal from surface
water and the mechanisms of pathogen removal. Specifically, the
following three points are considered:
Decomposition of organic matter is a major ecosystem process involving an array of different organisms, including bacteria, fungi and invertebrates. The main objective of this book is to provide students and laboratory instructors at universities and professional ecologists with a broad range of established methods to study plant litter decomposition. Detailed protocols for direct use in the field or laboratory are presented in an easy to follow step-by-step format. A short introduction to each protocol reviews the ecological significance and principles of the technique and points to key references. Although most methods are described for freshwater ecosystems, many will work equally well in the presented or slightly modified form for studies in marine and terrestrial environments.
This book discusses the dynamics and resource management qualities of the peri-urban interface to address climate change consequences, focusing on the peri-urban region of the global city of Bengalaru. In 5 chapters, the authors document the unique challenges experienced in peri-urban areas, including soil-water vegetation dynamics, local and regional impacts on water bodies (surface and groundwater), food production issues, and the inhibited adaptive capacity of local communities. The book also provides knowledge on implementations of environmental management by local institutions, government interventions that have acted as catalysts in promoting community based adaptation strategies, and the physical, social and economic aspects of rural-urban dynamics. The book not only adds to the scarce existing literature on peri-urban contexts, but also addresses the role of culture in protecting ecological landscapes and how traditions play an important role in coping with climate change. Furthermore, the authors expand on these climate change coping mechanisms in peri-urban areas, taking into account local cultural factors and interesting governance interventions in the context of health. The book will be of interest to planners, policy makers, and students and researchers engaged in rural-urban dynamics and climate change adaptation.
This book provides a fresh analysis of the demography, health and well-being of a major African city. It brings a range of disciplinary approaches to bear on the pressing topics of urban poverty, urban health inequalities and urban growth. The approach is primarily spatial and includes the integration of environmental information from satellites and other geospatial sources with social science and health survey data. The authors Ghanaians and outsiders, have worked to understand the urban dynamics in this burgeoning West African metropolis, with an emphasis on urban disparities in health and living standards. Few cities in the global South have been examined from so many different perspectives. Our analysis employs a wide range of GIScience methods, including analysis of remotely sensed imagery and spatial statistical analysis, applied to a wide range of data, including census, survey and health clinic data, all of which are supplemented by field work, including systematic social observation, focus groups, and key informant interviews. This book aims to explain and highlight the mix of methods, and the important findings that have been emerging from this research, with the goal of providing guidance and inspiration for others doing similar work in cities of other developing nations.
The Andaman and Nicobar Islands, India, consist of 572 islands with a land area of 8,249 km2. Their topography is hilly and undulating, with elevations up to 732 m on the Andaman and up to 568 m on the Nicobar Islands. They are known for their rich biodiversity and a very high degree of endemicity in all taxa, especially in plants, reptiles, fishes and corals. Their habitats include bays, mangroves, moist deciduous forests and evergreen forests. Comprising 20 chapters each written by an expert or professional in his/her particular field this book offers new insights into the fascinating faunal communities of these islands and provides the fundamentals for their conservation and environmental management.
Over the past twenty-five years, the effects of the spatial distribution and scaling of resources on animal populations have been increasingly studied in wildlife biology, landscape ecology, conservation biology, and related fields. However, spatial patterns change over time. In Temporal Dimensions of Landscape Ecology: Wildlife Responses to Variable Resources, the authors discuss the effects that temporal changes in resources have on animal populations. Resource availability and quality are not distributed homogeneously over time, depending for example on predictable changes in seasons, mating and birthing cycles, unpredictable resource pulses and weather-related phenomena, ecological disturbances, and historical legacies. Temporal Dimensions of Landscape Ecology brings together chapters that address the idea of current as well as historical temporal influences on resource availability, quality, and distribution. The authors draw attention to the neglected temporal issues so important to understanding species and community responses. This book will be of interest to both wildlife and conservation students and practitioners working with temporal and spatial scale issues.
International concern in scientific, industrial, and governmental communi ties over traces of xenobiotics in foods and in both abiotic and biotic envi ronments has justified the present triumvirate of specialized publications in and this field: comprehensive reviews, rapidly published research papers progress reports, and archival documentations. These three international publications are integrated and scheduled to provide the coherency essential for nonduplicative and current progress in a field as dynamic and complex as environmental contamination and toxicology. This series is reserved ex clusively for the diversified literature on "toxic" chemicals in our food, our feeds, our homes, recreational and working surroundings, our domestic animals, our wildlife and ourselves. Tremendous efforts worldwide have been mobilized to evaluate the nature, presence, magnitude, fate, and toxi cology of the chemicals loosed upon the earth. Among the sequelae of this broad new emphasis is an undeniable need for an articulated set of authoritative publications, where one can find the latest important world literature produced by these emerging areas of science together with docu mentation of pertinent ancillary legislation. Research directors and legislative or administrative advisers do not have the time to scan the escalating number of technical publications that may contain articles important to current responsibility. Rather, these individu als need the background provided by detailed reviews and the assurance that the latest information is made available to them, all with minimal literature searching.
This volume is a collection of the some of the most significant lectures that well-known experts presented at our two international summits on evolution (2005, 2009) as updated and revised chapters. The meetings took place on one of the large islands of the Galapagos archipelago (San Cristobal) at GAIAS (Galapagos Institute for the Arts and Sciences) of the Universidad San Francisco de Quito (USFQ), Ecuador. The main goal of the two Galapagos Summits on Evolution has been to bring together scientists and graduate students engaged in the study of evolution, from life s origin to its current diversity. Because of their historical significance, the Galapagos are a unique venue for promoting comprehensive research on evolution and ecology and to make the research results available to students and teachers everywhere, but especially from developing countries. As shown by the enthusiastic attendance at both summits and the many suggestions to keep them continuing, the meetings have opened new opportunities for students from Ecuador and other Latin American countries to be inspired by some of the most brilliant minds in evolutionary science.
This book pursues a multidisciplinary approach in order to evaluate the socio-ecological dimensions of infectious diseases in Southeast Asia. It includes 18 chapters written by respected researchers in the fields of history, sociology, ecology, epidemiology, veterinary sciences, medicine and the environmental sciences on six major topics: (1) Infectious diseases and societies, (2) Health, infectious diseases and socio-ecosystems; (3) Global changes, land use changes and vector-borne diseases; (4) Monitoring and data acquisition; (5) Managing health risks; and (6) Developing strategies. The book offers a valuable guide for students and researchers in the fields of development and environmental studies, animal and human health (veterinarians, physicians), ecology and conservation biology, especially those with a focus on Southeast Asia.
The book presents an integration of existing ecosystem theories in
such a comprehensive way as to enable a full ecological and
theoretical pattern to be presented. It shows that ecosystems and
their reactions may be understood, provided that all basic systems
ecology is applied to different aspects of the properties of
ecosystems. Since the publication of the previous two editions of
this book, ongoing research and discussions on an international
scale have greatly clarified and enhanced this pattern. This
progress is presented as Chapter 16 in this new, third edition. It
is shown that the integrated ecosystem theory presented can be
applied to explain various ecological observations and rules.
This volume gathers together a representative set of examples from the many varied spatial techniques and analytical approaches being used by geographers, ecologists, and biogeographers to study plant and animal distributions, to assess processes affecting the observed patterns at selected spatial and temporal scales, and to discuss these examples within a strong conceptual spatial and/or temporal framework. Therefore, the aims of this volume are to: Identify the key spatial concepts that underpin Geographic Information Science (GISc) in biogeography and ecology; Review the development of these spatial concepts within geography and how they have been taken up in ecology and biogeography; Exemplify the use of the key spatial concepts underpinning GISc in biogeography and ecology using case studies from both vegetation science and animal ecology/biogeography that cover a wide range of spatial scales (from global to micro-scale) and different geographical regions (from arctic to humid tropical); and Develop an agenda for future research in GISc, which takes into account developments in biogeography and ecology, and their applications in GISc including remote sensing, geographic information systems, quantitative methods, spatial analysis, and data visualisation. B#/LISTB# The idea for GIS and Remote Sensing Applications in Biogeography and Ecology arose from two joint symposia organized by the Biogeography Study Group of the International Geographical Union; the Biogeography, Remote Sensing, and GIS Specialty Groups of the Association of American Geographers, and the Biogeography Research Group of the Royal Geographical Society-Institute of British Geographers and held in Leicester andHonolulu in 1999. These groups represent the majority of geographers conducting research in biogeography and ecology and teaching this material to geographers. While this material is increasingly being covered in a variety of disciplines and sub-disciplines (e.g., large-area ecology, landscape ecology, remote sensing and GIS), many researchers in these fields lack the training in spatial concepts behind the techniques that they utilize. The spatial concepts that are covered in this book are richer than those found within landscape ecology at the present time, and GIS and Remote Sensing Applications in Biogeography and Ecology will promote the use of many of these concepts among landscape ecologists.GIS and Remote Sensing Applications in Biogeography and Ecology is suitable as a secondary text for a graduate level course, and as a reference for researchers and practitioners in industry.
This is the third volume of Advances in Microbial Ecology to be produced by the current editorial board. I would, therefore, like to take this opportunity to thank my co-editors for all their efforts, particularly in maintaining a balance of subject matter and geographical distribution of the contributions. Volume 15 is no exception in that we have a balance between the prokaryo tic and eukaryotic organisms and a range of subject matter from applied ecology through process ecology to ecological theory. The response from our readers has been encouraging in the sense that the breadth of coverage is much appreciated, particularly by teachers and postgraduate/postdoctoral researchers. However, we still strive to improve our coverage and particularly to move wider than the North America/Europe axis for contributions. Similarly, we would like to see coverage of the more unusual microbes, perhaps a chapter devoted to the ecology of a particular species or genus. There must exist many ecological notes on "rarer" organisms that have not found their way into the standard textbooks or taxonomic volumes; properly compiled these could provide valuable information for the field ecologist. Ecological theory has, until recently, been the domain of the "macroecolo gist. " Recent advances in molecular techniques will ensure that the microbial ecologist will playa more significant role in the development of the subject. We shall not, therefore, change our policy of encouraging our contributors to specu late, permitting them sufficient space to develop their ideas.
Complex chemical mixtures impact our health every day. In the United States, and also in Central and Eastern Europe, there are a number of locations where complex chemical mixtures have been released to environmental media. Although exposure to mixtures is common, minimal information exists to quantify these exposures, or to determine their impact on human or ecological receptors. These proceedings present some of the most current research conducted to quantify complex mixtures in the environment and investigate their potential impact on human health. Many of the manuscripts reported in these proceedings represent the most up-to-date measurements of population exposures in Central and Eastern Europe. These studies are of value to health and environmental professionals around the world as they develop strategies for assessing exposures, remediating contaminated environments, and improving public health.
Post-agricultural studies have been central to the development of both the science of plant ecology and ecology in general. The study of old field succession in particular allows us to observe the development of the structure and function of communities, as well as understand the roles of history and initial conditions in that process. Understanding old field succession can help the public address important scientific and social issues, such as deforestation and forest regeneration, forest restoration, sustainability of agriculture, maintenance of biodiversity, and impacts of global climate change on forest dynamics. Post-Agricultural Succession in the Neotropics focuses on published scientific work and its implications for wise management of old field ecosystems in the neotropics, where conversion of land to cropping systems is the most common kind of disturbance and many landscapes are defined by areas recovering from agriculture. Written for researchers, professionals, and students of ecology, the book provides a background in old field ecosystems and proposes restoration strategies and a trajectory for future research. methodologies and management strategies proposed.
Arthropods are invertebrates that constitute over 90% of the animal kingdom, and their bio-ecology is closely linked with global functioning and survival. Arthropods play an important role in maintaining the health of ecosystems, provide livelihoods and nutrition to human communities, and are important indicators of environmental change. Yet the population trends of several arthropods species show them to be in decline. Arthropods constitute a dominant group with 1.2 million species influencing earth's biodiversity. Among arthropods, insects are predominant, with ca. 1 million species and having evolved some 350 million years ago. Arthropods are closely associated with living and non-living entities alike, making the ecosystem services they provide crucially important. In order to be effective, plans for the conservation of arthropods and ecosystems should include a mixture of strategies like protecting key habitats and genomic studies to formulate relevant policies for in situ and ex situ conservation. This two-volume book focuses on capturing the essentials of arthropod inventories, biology, and conservation. Further, it seeks to identify the mechanisms by which arthropod populations can be sustained in terrestrial and aquatic ecosystems, and by means of which certain problematic species be managed without producing harmful environmental side-effects. This edited compilation includes chapters contributed by over 80 biologists on a wide range of topics embracing the diversity, distribution, utility and conservation of arthropods and select groups of insect taxa. More importantly, it describes in detail the mechanisms of sustaining arthropod ecosystems, services and populations. It addresses the contribution of modern biological tools such as molecular and genetic techniques regulating gene expression, as well as conventional, indigenous practices in arthropod conservation. The contributors reiterate the importance of documenting and understanding the biology of arthropods from a holistic perspective before addressing conservation issues at large. This book offers a valuable resource for all zoologists, entomologists, ecologists, conservation biologists, policy makers, teachers and students interested in the conservation of biological resources.
Known as "a dream place for scientists" the Lamto savannas, located on the edge of the Cote d'Ivoire rain forests, are some of the only savannas in the world where ongoing ecological research has endured for over forty years. Drawing from and synthesizing this abundance of research, the book examines the structure, function, and dynamics of the Lamto humid savanna. Beginning with the history of the Lamto ecology station, proceeding on to an overview of the major enivronmental conditions of the site, and specifically examining the integrative view of energy and nutrient fluxes relative to the dynamics of the region's vegetation, this exacting work is as unique and treasured as Lamto itself.
Biological diversity is important for ecosystem function and services, which in turn is essential for human well-being. Under the Convention on Biological Diversity, international efforts have been made to achieve a significant reduction in the current rate of biodiversity loss. The loss continues, however. The Asia-Pacific region includes both developing countries with high biodiversity and developed countries with sophisticated data collection and analyses, but only limited information about the status quo of biodiversity in this region has been available. Many Asia-Pacific countries have rapidly grown their economies and social infrastructures, causing a loss of biodiversity and requiring an urgent mandate to achieve a balance between development and conservation in the region. In December 2009, scientists successfully organized the Asia-Pacific Biodiversity Observation Network in the region, to establish a network for research and monitoring of ecosystems and biodiversity and to build a cooperative framework. The present volume is the first collection of information on biodiversity in the Asia-Pacific and represents a quantum step forward in science that optimizes the synergy between development and biodiversity conservation.
Carbon and carbon dioxide always played an important role in the geobiosphere that is part of the Eartha (TM)s outer shell and surface environment. The booka (TM)s eleven chapters cover the fundamentals of the biogeochemical behavior of carbon near the Eartha (TM)s surface, in the atmosphere, minerals, waters, air-sea exchange, and inorganic and biological processes fractionating the carbon isotopes, and its role in the evolution of inorganic and biogenic sediments, ocean water, the coupling to nutrient nitrogen and phosphorus cycles, and the future of the carbon cycle in the Anthropocene. This book is mainly a reference text for Earth and environmental scientists; it presents an overview of the origins and behavior of the carbon cycle and atmospheric carbon dioxide, and the human effects on them. The book can also be used for a one-semester course at an intermediate to advanced level addressing the behavior of the carbon and related cycles. "By thoroughly researching the fundamental principles of the biogeochemical cycling of carbon, Mackenzie and Lerman have been able to illustrate with clarity the profound impact of humans, as a biogeological agent, are having on the global carbon cycle. Never before has there been a more pressing need to understand the intricacies of the geobiosphere with respect to the cycling of planetary carbon, and this text provides the most thoroughly researched, authoritative, and definite text of the global carbon cycle that exists to date. This book is a contemporary appraisal of knowledge on the global carbon cycle and should become the standard scientific reference manual for all those involved in the fight against climate change. It is difficultto think of a more important book for one of the greatest issues facing humanity in the 21st century." Review published in J. Environm. Qual. 36: 1546 (2007, by Dr. Jeffrey P. Obbard, Division of Environmental Sciences & Engineering, Tropical Marine Science Inst. National Univ. of Singapore "Mackenzie and Lerman's book is the culmination of two splendid careers dedicated to understanding the carbon cycle. Ita (TM)s everything you always wanted to know about carbon biogeochemistry past, present, and future." Lee R. Kump, Dept. of Geosciences, Pennsylvania State University, USA "Majestic in scope; this text builds from fundamentals to front-line research, showing the pivotal role of the carbon cycle in earth system science." Rob Raiswell, University of Leeds, UK "Using skills honed from decades of leadership in the field, Mackenzie and Lerman ably guide us along the pathways of carbon cycling in Eartha (TM)s outer layers. This is an essential journey for anyone interested in the origin and evolution of life and its fate under human influence." Tim Lyons, University of California, Riverside, USA
Large-scale natural catastrophes are environmental phenomena. Numerous studies in recent years have concluded that the frequency of occurrence of such natural disasters have been incereasing. leading to an enhanced risk of very considerable human and economic losses and the widespread destruction and pollution of habitats, settlements and infrastructure. In 2001 over 650 natural disasters happened around the globe with economic losses exceeding $35 billion. 2004 ended with the South East Asian tsunami on 26th December with its huge toll on life and local economics and this demonstrated that the efffects of such disasters are most keenly felt in poorer or developing regions. The problem of natural disaster prediction and the implementation of environmental monitoring systems to receive, store and process the information necessary for solutions of specific problems in this area, have been analysed by the three authors of this book, all of whom are internationally respected experts in this field.
Arising initially from a conference, the papers published here have been integrated into book form to provide information on human activities and the tropical rainforest in the past and present, and on the possible future of the rainforest, in a unique way. Other books have considered some, but not all, of these themes; however, none has stressed the continuity of change over time and its possible outcome for the people of the forest as well as for the forest itself. Because of the approach taken, this book should appeal across traditional disciplinary boundaries. Indeed a prime aim has been to suggest that rainforest, because of its complexity and the complexity of people-rainforest relationships throughout time, deserves study from a broad perspective. This book poses more questions than answers about the rainforest and it is hoped that it will encourage readers to think about the rainforest in a wider way than hitherto. This book is aimed at geographers (physical and human), social anthropologists, archaeologists, pedologists, foresters and tropical botanists and will be of value to graduates of various disciplines setting out to research the rainforest.
There is a plethora of information available on the river Ganga in the form of books, blogs, articles, websites, videos. Unfortunately, most of the information about this famous river is in a scattered form and reproduced from unverified sources. This contributed volume is the first multi-author volume publication on this subject. The River Ganga includes a vast array of topics written by several authors of distinction. Topics include; hydrology, tributaries, water uses, and environmental features such as river water quality, aquatic and terrestrial flora/fauna, natural resources, ecological characteristics, sensitive environmental components and more. Part I gives a basic introduction of the Ganga river. The existing data and available information from various sources has been compiled in a pictorial fashion in the form of cmaps. Its cultural importance with changing times is also discussed. Part II looks at the rich biodiversity of the Ganga Basin. It gives a detailed description of the major floral and faunal biodiversity with special emphasis on the national aquatic animal dolphin and Sunderbans, the largest mangrove wetland in the world. Part III examines 'The Ganga Water as it flows'. It focuses on the water quality as well as its associated challenges. Part IV looks at the complexities of issues confronting the river 'Ganga in changing times' be it snowmelt runoff, river bank erosion hazards and hydropower assessments; how the factors of population, poverty and pollution contribute to the fate of the river. Part IV touches on economic aspects derived from the river such as business opportunities and tourism.
It is more and more evident that our living system is completely disturbed by human intrusion. Such intrusion affects the functioning of entire systems in ways we do not yet fully understand. We use paradigms such as the disturbance to cover large and deep gaps in our scienti?c knowledge. Human ecology is an uncertain terrain for anthropologists, geographers, and ecologists and rarely is expanded to include the social and economic realms. The integration of different disciplines and the application of their many paradigms to problems of environmental complexity remains a distant goal despite the many efforts that have been made to achieve it. Philosophical and semantic barriers are erected when such integration is pursued by pioneering scientists. Recently, evolutionary ecology has shown great interest in the spatial processes well described by the emerging discipline of landscape ecology. But this interest takes the form of pure curiosity or at worst, of skepticism toward the real capacity of landscape ecology to contribute to the advancement of ecological science. The past two centuries have been characterized by huge changes occurring in the entire ecosphere. Global changes are the effects of human intervention at a planetary scale, with consequent degradation of the environment creating an e- logical debt for future generations. On the other side of the issue, new technologies have improved the welfare of billions of people and have given hope to many other billions that they may also see such improvement in the near future.
First published in 1981, Dynamics of Large Mammal Populations was written by experts from four continents and six countries. It is a collection of papers on the population dynamics of large mammals and was the first synthesis of work in the field. The book helped provide identity and coherence to an emerging field. It has become a much-sought-after book. The theoretical and empirical studies presented demonstrate the ways in which numbers of animals in large mammal populations change over time in response to a variety of factors. The studies cover a wide variety of species - including both terrestrial and marine mammals - and compare the population dynamics of various groups such as herbivores, carnivores, ungulates, cetaceans and pinnipeds. Included are species involved in controversial population management problems. Also covered are advances in managing the populations of large mammals, and advances in the theoretical basis of large mammal population dynamics. Numerous examples detail the interaction of mammals with their ecosystems. Population biologists, wildlife biologists and managers, government researchers, environmentalists and marine mammal scientists can use the information made available here as a basis for comparative research and practical applications. "The book contains an excellent mix of theoretical chapters, general overviews, and studies of specific animal speces, ranging from seals and whales to lions and elephants, taking deer, wolves, and grizzly bears along the way... But to the specialist it will be indispensable, forming as it does the only authoritative volume that deals with the population dynamics of this important group of animals." ORYX Fauna & Flora Preservation Society, July, 1983. "One immediately realizes, by skimming the citations of the different chapters, that the researchers, working on such animals as whales, bears, seals, lions, and elephants had not been talking to one another, and that this book represents something of a first in this regard." Mathematical Biosciences, 1983. "The book will be of particular interest and value to wildlife biologists faced with problems of managing wildlife resources and to people who use the resources." The Quarterly Review of Biology, 1982. "This is an excellent book. One doesn't have to be a population biologist to understand the material. Best of all, the authors are refreshingly frank about areas of ignorance in population biology and the failure of even the best simulaion models to fit the real world... To sum up, there is food for thought in this volume for every zoologist with an interest in population biology and especially for those who study large mammals." BioScience 1982. "In bringing a wealth of research effort to a wider readership, this book cannot fail to stimulate" Biometrics, 1982. |
