Almost 50% of the total area of Austria is forested, and the forests are dominated by commercially valuable stands of Norway spruce ( (Picea abies). The few remaining forests that resemble the natural vegetation composition are located in forest reserves with restricted management. These natural forests are used as reference systems for evaluating silvicultural research on sustainable forest management. Natural forests are expected to have high biodiversity, where the structural richness of the habitat enables complex relationships between fauna, flora, and microflora. They also provide refugia for rare plants and animals found only in natural forest types. Austria had 180 of these forest reserves up to the year 2003. Most of these forests are privately owned, and owners are compensated by the government for loss of income associated with conservation status. The Ministerial Conference for the Protection of Forest Ecosystems (MCPFE) has launched a world-wide network of protected forest areas which should cover all major forest types (MCPFE and UNECE/FAO, 2003). The sites selected for our investigation of soil conditions and communities were chosen by vegetation ecologists and soil scientists. The stands have developed under natural competition conditions with no management interventions. All sites were well documented with known forest history. Our set of sites spans gradients of environmental conditions as well as species composition, providing a realistic evaluation of the interactions of biotic and abiotic factors.

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.

This book describes the latest research advances, innovations, and applications in the field of water management and environmental engineering as presented by leading researchers, engineers, life scientists and practitioners from around the world at the Frontiers International Conference on Wastewater Treatment (FICWTM), held in Palermo, Italy in May 2017. The topics covered are highly diverse and include the physical processes of mixing and dispersion, biological developments and mathematical modeling, such as computational fluid dynamics in wastewater, MBBR and hybrid systems, membrane bioreactors, anaerobic digestion, reduction of greenhouse gases from wastewater treatment plants, and energy optimization. The contributions amply demonstrate that the application of cost-effective technologies for waste treatment and control is urgently needed so as to implement appropriate regulatory measures that ensure pollution prevention and remediation, safeguard public health, and preserve the environment. The contributions were selected by means of a rigorous peer-review process and highlight many exciting ideas that will spur novel research directions and foster multidisciplinary collaboration among different water specialists.

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.

This book reviews the current state of knowledge on, recent advances in, and future prospects of Montenegrin river basins in the context of anthropogenic activities. Edited by three respected experts in the field, the book begins with an introduction to the specific hydrogeological conditions in Montenegro and critical reflections on the impact of hydropower projects. It then reviews the vulnerability of river ecosystems, exploring potential genotoxic effects and water quality, and explaining typology and monitoring of these aspects, and particularly highlighting mollusk assemblages and monitoring of intermittent rivers. The closing chapters focus on the impact of river flooding and discuss controversial projects aiming to find an approach mutually acceptable to all stakeholders. Given its scope, the book is an indispensable resource for scientists in academia and the water industry, as well as for decision-makers in the field investigating the interactions between land and water, limnology and biota, and natural and cultural resources.

This book offers a unique collection of inter- and multidisciplinary studies on river systems. Rivers have been the prime source of sustenance since the advent of civilization and river systems often form the basis for agriculture, transport, water, and land for domestic, commercial, and industrial activities, fostering economic prosperity. A river basin is a basic geographical and climatological unit within which the vagaries of natural processes act and manifest themselves at different spatio-temporal scales. Even if compared side-by-side, no two river basins respond to natural processes in the same way and thus, it has long been recognized that each river basin is unique. Hence, any developmental activity or conservation effort has to be designed and implemented to match each unique river basin. With the burgeoning population and increasing dependency on natural resources, understanding and maintaining river systems has become increasingly important. This book provides a varied reference work on and unprecedented guidelines for conducting and implementing research on river basins, and for managing their ecological development.

This authoritative but highly accessible book presents the reader with a powerful framework for understanding the critical role of the energy return on investment (EROI) in the survival and well-being of individuals, ecosystems, businesses, economies and nations. Growth and development are fundamental and ubiquitous processes at all scales, from individuals to food crops to national economies. While we are all familiar with the concepts of economic growth and living standards as measured by gross domestic product (GDP), we often take for granted the energy use that underpins GDP and our expectations for year-on-year growth. In this book, you will learn how these measures of "progress" are completely dependent on the balance that can be achieved between energy costs (inputs) and gains. Nothing is made or moved without an energy surplus, and it is the EROI of available energy sources more than any other single factor that determines the shape of civilization. Nearly all politics and economics assume that policy and market forces are the levers upon which future outcomes will hinge. However, this book presents many examples of historical and current events that can be explained much more clearly from an energetic perspective. In addition, a future scenario is developed that gives a central place to EROI in assessing the potential of governmental and private initiatives to substitute so-called renewable energy sources for diminishing stocks of fossil fuels. When cheap fossil fuels are no longer available in the abundance needed to mask economic problems and power business as usual, it will be EROI more than the plethora of "green" technologies that creates the boundary conditions for a sustainable future.

The purpose of this work is to develop a better understanding and thinking about the cumulative impacts of multiple natural resource development projects. Cumulative impacts are now one of the most pressing, but complex challenges facing governments, industry, communities, and conservation and natural resource professionals. There has been technical and policy research exploring how cumulative environmental impacts can be assessed and managed. These studies, however, have failed to consider the necessary integration of community, environment and health. Informed by knowledge and experience in northern British Columbia, this book seeks to expand our understanding of the cumulative impacts of natural resource development through an integrated lens. The book offers a timely response to a growing imperative - proposing integrative response to multiple natural resource developments in a way that addresses converging environment, community and health issues. Informed by the editors' experiences across several complementary areas of expertise, we envision this book as appealing to a wide range of researchers, educators and practitioners, with relevance to a growing audience with appetite for and interest in integrative approaches.

A unified theory of conservation that addresses the broad problem of conservation, the principles that inform conservation choices, and the application of those principles to the management of the natural world. The conservation of natural resources, like that of any other asset, involves trade-offs. Yet, in a world faced with the harsh realities of climate change, crafting the right environmental policies is an increasingly urgent task. In Conservation, Charles Perrings and Ann Kinzig bring together new research in economics and biodiversity to investigate conservation decisions and the theory behind them. Perrings and Kinzig apply the concept of conservation broadly to examine how the principles of conservation apply to the management of the natural world. They demonstrate that the same basic principles serve as the foundation of all rational conservation decisions, from managing financial assets to safeguarding at-risk ecosystems. Whether someone is deciding to hold or dispose of a stock or whether to exploit or preserve a natural resource, they are better off choosing to conserve a resource when its value to them, if conserved, is greater than its value when converted. The book also considers the context of such conservation decisions. Just as national tax rules influence choices about financial investments, environmental regulations within countries, and environmental agreements between countries, impact the decisions regarding natural resources. Building on their basic theory of conservation, Perrings and Kinzig address key issues in the field of environmental economics, including the valuation of ecosystem services and environmental assets; the limits on the substitutability of produced and natural capital; and the challenges posed by the often weak markets for ecosystem services oriented toward the public good. They also address the problem of scale: while decisions might be easier to make at the local level, many conservation policies need to apply at either the national or international level to succeed. Written by experts from both social and hard sciences, this book presents a unified theory of conservation and provides a model for a more effective way to approach the vitally important issue.

This book explores how individuals and communities perceive and understand climate change using their observations of change in the world around them. Because processes of climatic change operate at spatial and temporal scales that differ from those of everyday practice, the phenomenon can be difficult to understand. However, flora and fauna, which are important natural and cultural resources for human communities, do respond to the pressures of environmental change. Humans, in turn, observe and adapt to those responses, even when they may not understand their causes. Much of the discussion about human experiences of our changing climate centers on disasters and extreme events, but we argue that a focus on the everyday, on the microexperiences of change, has the advantage of revealing how people see, feel, and make sense of climate change in their own lives. The chapters of this book are drawn from Asia, Europe, Africa, and South and North America. They use ethnographic inquiry to understand local knowledge and perceptions of climate change and the social and ecological changes inextricably intertwined with it. Together, they illustrate the complex process of coming to know climate change, show some of the many ways that climate change and our responses to it inflict violence, and point to promising avenues for moving toward just and authentic collaborative responses.

USDA Forest Service Experimental Forests and Ranges (EFRs) are scientific treasures, providing secure, protected research sites where complex and diverse ecological processes are studied over the long term. This book offers several examples of the dynamic interactions among questions of public concern or policy, EFR research, and natural resource management practices and policies. Often, trends observed - or expected -- in the early years of a research program are contradicted or confounded as the research record extends over decades. The EFRs are among the few areas in the US where such long-term research has been carried out by teams of scientists. Changes in society's needs and values can also redirect research programs. Each chapter of this book reflects the interplay between the ecological results that emerge from a long-term research project and the social forces that influence questions asked and resources invested in ecological research. While these stories include summaries and syntheses of traditional research results, they offer a distinctly new perspective, a larger and more complete picture than that provided by a more typical 5-year study. They also provide examples of long-term research on EFRs that have provided answers for questions not even imagined at the time the study was installed.

The scientific community has voiced two general concerns about the future of the earth. Climatologists and oceanographers have focused on the changes in our physical environment -- changes in the climate, the oceans, and the chemistry of the air we breathe. Environmental biologists, on the other hand, have addressed issues of conservation and the extinction of species. There is increasing evidence that these two broad concerns are intertwined and mutually dependent. Past changes in biodiversity have both responded to and caused changes in Earth's environment. In its discussions of ten key terrestrial biomes and freshwater ecosystems, this volume uses our broad understanding of global environmental change to present the first comprehensive scenarios of biodiversity for the twenty-first century. Combining physical earth science with conservation biology, Global Biodiversity in a Changing Environment provides a starting point for regional assessments on all scales. The book will be of interest to those concerned with guiding research on the changing environment of the earth and with planning future policy, especially in accordance with the Global Biodiversity Convention.

Weeds are the main biological constraint to crop production throughout the year. Uncontrolled weeds could cause 100% yield loss. In Australia, the overall cost of weeds to Australian grain growers was estimated at AU$ 3.3 billion annually. In terms of yield losses, weeds amounted to 2.7 million tonnes of grains at a national level. In the USA, weeds cost US$ 33 billion in lost crop production annually. In India, these costs were estimated to be much higher (US$ 11 billion). These studies from different economies suggest that weeds cause substantial yield and economic loss. Biology and Management of Problematic Weed Species details the biology of key weed species, providing vital information on seed germination and production, as well as factors affecting weed growth. These species include Chenopodium album, Chloris truncata and C. virgate, Conyza bonariensis and C. canadensis, Cyperus rotundus, and many more. This information is crucial for researchers and growers to develop integrated weed management (IWM) strategies. Written by leading experts across the globe, this book is an essential read to plant biologists and ecologists, crop scientists, and students and researchers interested in weed science.

This book contains some of the papers which were presented at the NATO Science, Environmental Security, Advanced Research Workshop on "Implementing Ecological Integrity: Restoring Regional and Global Environmental and Human Health" held in Budapest from June 26 to July 1, 1999. All papers presented are summarized in the Introduction and, in some cases, shorter versions are published. A mUltidisciplinary core of American and Western European participants had met over the preceeding years to discuss the concept of ecological integrity. The term "ecological integrity" is found in environmental policy documents but, generally, is not defined. It competes with other recent terms, or environmental narratives, such as "ecosystem health" and "sustainable development" and also with older ones such as "conservation." Therefore, it is deemed important not only to sort out the definitions of these concepts but also to find out whether their practical implications differ. Moreover, it was interesting to find out whether participants from Central and Eastern European Countries (CEEC) and, more generally, from NATO partner countries would be, first, responsive to this concept and, second, would hold different views of it. This explains the broad, albeit not always consistent, range oftopics which are covered in this book. The core group learned that CEEC and other NATO partners participants were responsive to the concept but that they were less exclusive of human influence.

This book offers an environmental-economic analysis of exploited ecosystems with a clear policy orientation. The study tries to move beyond traditional economic fishery analysis in two respects. First, several theoretical and numerical models are offered that combine economic and ecological descriptions of fisheries. These models give special attention to spatial processes as well as to combining exploitation and conservation objectives. Second, valuation and stakeholder concerns are addressed in empirical analyses employing both qualitative and quantitative approaches. The latter is done by using advanced methods of monetary valuation. In addition, the 1st part of the book presents short, introductory overviews of integrated assessment, economic modeling of fishery management, and incorporating uncertainty in fisheries analysis. These introductions will allow readers of a variety of disciplines to create a sufficient background so as to be able to read later parts of the book.

This book is geared for advanced level research in the general subject area of remote sensing and modeling as they apply to the coastal marine environment. The various chapters focus on the latest scientific and technical advances in the service of better understanding coastal marine environments for their care, conservation and management. Chapters specifically deal with advances in remote sensing coastal classifications, environmental monitoring, digital ocean technological advances, geophysical methods, geoacoustics, X-band radar, risk assessment models, GIS applications, real-time modeling systems, and spatial modeling. Readers will find this book useful because it summarizes applications of new research methods in one of the world s most dynamic and complicated environments. Chapters in this book will be of interest to specialists in the coastal marine environment who deals with aspects of environmental monitoring and assessment via remote sensing techniques and numerical modeling."

The southwestern Australian flora is unique in the world, not only for its biodiversity and endemism, but also for its functional biodiversity. It also contains the world's most nutrient-impoverished soils, has a prolonged-summer period and the vegetation is extremely fire-prone. These conditions have engendered an array of survival adaptations that have evolved in these harsh conditions across a diverse range of species. It is well recognised that the southwest flora has the toughest and most spiny vegetation of the world, the greatest number of species that store their seeds in woody fruits, and the most specialised means of obtaining limited soil nutrients and water. This book focuses on the survival mechanisms, adaptations and ecology of the unique Southwest Australian flora (restricted here to flowering plants). The book begins with an examination of how the flora has evolved into the present forms. It describes further in detail the adaptive responses of the flora to the main environmental pressures influencing survival - fire, summer drought, nutrient-impoverished soils, pollination and seed dispersal agents. Specialised responses to obtain essential nutrients are presented in three chapters - carnivorous plants, parasitic plants and specialised roots. An entire chapter is devoted to leaves, with an insight into how leaves may assist in protecting flowers and fruits from herbivores and seed-eaters. The book provides an ecological perspective on how the flora has evolved complex strategies to ensure species survival in the relatively harsh seasonal climate of a Mediterranean-type ecosystem.

The novelty of the book is a strong focus on perception, perspectives and prediction by scientists with profound insight into the ecology of ecosystems or into human demands and activity. The challenge is to bridge from empirical data and the knowledge of the past to the possibilities of the performance in the future. We assume that there is scope for more cooperation between the fields of ecology and practical philosophy or other social sciences in organising ecosystems and shaping the cultural future of humankind, and that such collaboration should be accorded considerably more priority. This book deals with environmental processes seen within a framework of the nature of ecosystems and human cultures. The future of the environment, the development of ecosystems and effective nature conservation management are the essentials of this book. Human nature and culture, and in particular their interactions, are interpreted as a set of rules and as given. The aim is not only to assess the significance of human influence on species composition and biodiversity but also to weigh up the subsequent potentials for action. In this book we will analyze the problems independently of one another, even if they are interconnected. This book focuses on perspectives and prognoses for the impacts of anthropogenic activity on ecosystems and thus on species conservation. Its goal is to improve assessments of the impacts of human activity on the environment. We are aware that prognoses have very often proven to be false. It is difficult to impossible to be able to predict with precision how evolution and ecosystems will change in future under anthropogenic influence. This strengthens our resolve to attempt to retain the highest possible degree of scientific integrity and professionalism and not to shy away from expressing the uncertainty of our own ideas and prognoses. We venture prognoses in this book and we will fail. However, we hope that we will be wrong on the right side.

This book focuses on the development of DGT (diffusive gradients in thin films) and the related techniques for measuring and investigating the geochemical process and P transfer across the sediment/water or sediment/root interface in lakes. A series of DGT techniques such as new types of probes, test methods in sediment or the rhizosphere, DIFS (DGT induced fluxes in sediments and soils) model for kinetic P exchange, CID (computer imaging densitometry) for S(-II), and microchelex gel/LA-ICP-MS (laser ablation inductively coupled plasma mass spectrometry) have been developed. The corresponding chapters on the theory and methodology of DGT, the "internal P loading" or P transfer across sediment/root in two lakes, provide insights into the research method and conclusions, including the P release mechanism, the quantification of "internal P loading", kinetic P exchange in DGT/sediment interface, Fe- or S(-II)-microniches at submillimeter scales in sediments for the prediction of P release, and DGT as a surrogate for the prediction of P uptake by roots. It also offers new perspectives in the fields of P analysis and P process in micro-interfaces in lakes using DGT techniques. The P remobilization from Fe-bound P, the coupled Fe-S(-II)-P geochemical reaction and algae biomass breakdown causing P release, are elucidated using DGT methods in sediment layers. DGT parameters and curves for time or distance derived from DIFS can be used to assess kinetic P release in the sediment microzone. CID and LA-ICP-MS methods deliver Fe- and S(-II) images at submillimeter scales, which can be used for the quantification of flux related to microniche peaks and the prediction of P release from Fe-microniche or Fe-S(-II)-P geochemical reactions. DGT measurements in-situ in rhizosphere or rhizonbox can give CE (effective concentration) and CDGT values for the prediction of P accumulated in plant tissues. This book provides a valuable reference resource for senior graduate students, lecturers and researchers in the fields of the geochemical process of eutrophic elements in lakes, lake eutrophication mechanism and environmental analysis.

From Fossils to Astrobiology reviews developments in paleontology and geobiology that relate to the rapidly-developing field of Astrobiology, the study of life in the Universe. Many traditional areas of scientific study, including astronomy, chemistry and planetary science, contribute to Astrobiology, but the study of the record of life on planet Earth is critical in guiding investigations in the rest of the cosmos. In this varied book, expert scientists from 15 countries present peer-reviewed, stimulating reviews of paleontological and astrobiological studies. The overviews of established and emerging techniques for studying modern and ancient microorganisms on Earth and beyond, will be valuable guides to evaluating biosignatures which could be found in the extraterrestrial surface or subsurface within the Solar System and beyond. This volume also provides discussion on the controversial reports of "nanobacteria" in the Martian meteorite ALH84001. It is a unique volume among Astrobiology monographs in focusing on fossil evidence from the geological record and will be valuable to students and researchers alike.

Riparian forests along streams and rivers are diverse in species, structure, and regeneration processes, and have important ecological functions in maintaining landscape and biodiversity. This book discusses riparian forests from subpolar to warm-temperate zones, covering headwater streams, braided rivers on alluvial fans, and low-gradient meandering rivers. It presents the dynamics and mechanisms that govern the coexistence of riparian tree species, tree demography, the response to water stress of trees, and the conservation of endangered species, and focuses on natural disturbances, life-history strategies, and the ecophysiology of trees. Because many riparian landscapes have been degraded and are disappearing at an alarming rate, the regeneration of the remaining riparian ecosystems is urgent. With contributions by more than 20 experts in diverse fields, this book offers useful information for the conservation, restoration, and rehabilitation of riparian ecosystems that remain in world streams and rivers.

Antimicrobial resistance is recognised among the world’s most challenging problems. Despite its global spread, Africa, specifically sub-Saharan Africa, is the most affected by this malaise. Poor living conditions and inadequate access to sanitation and potable water supplies are among contributing factors that have influenced a high disease burden on the continent, requiring extensive antimicrobials. Weak health systems and the absence of firm policies further aggravate the problem, as the use of antimicrobials is mostly unregulated. The increasing demand for animal protein to meet the starving populations’ demands has also influenced the use of these antimicrobials, including those banned on other continents, for food animal production. The ripple effect of indiscriminate use in humans and animals is the massive discharge of antimicrobials, their residues, antimicrobial-resistant microorganisms and their associated genes into the environment.  This 14-chapter unique masterpiece presents the AMR problem in African, addressing the various compartments of the One Health – humans, animals, and the environment, to illustrate the need for concerted efforts in the fight against AMR, especially in Africa. Authors from the four cardinal points present diverse aspects of AMR in Africa, starting with behavioural and social drivers of AMR in Africa. Antimicrobial stewardship in an African context is also discussed. AMR in humans is presented through studies on antibiotic-resistant neonates and nontyphoidal Salmonella infections and the clinical relevance of the genetics of viral resistance. Topics on AMR in mastitis, biosecurity in animal farming and the linkage between disinfectants and AMR are discussed. The environmental dimension of AMR is discussed, notably in the aquatic environment, and its implication for aquaculture and irrigation and using nanomaterials to treat polluted waters from such environments are highlighted. Finally, Africa’s rich floral diversity is portrayed as an eco-friendly and cost-effective approach to combat AMR. Hopefully, the work presented will spur greater collaboration between scientists, environmental, animal and human health practitioners, the general population, and policymakers to assimilate and implement the One Health approach to combating AMR, rather than working in silos on their various sectors

This title includes a number of Open Access chapters. Environmental chemistry is an interdisciplinary field of study that involves the science of ecology as well as chemistry. Environmental chemistry covers the basic chemistry and biochemistry that occur naturally in the world around us. It focuses on the air, water, and land. Environmental science normally begins by determining the chemical reactions that are occurring in the environment when all systems are in balance and then goes on the discover how chemistry has changed when there is an imbalance caused by stress or pollution. The field is constantly changing, with new discoveries being made all the time. The availability of new and more sensitive instruments in analytical science is enabling the detection of smaller and smaller concentrations of pollutants in the environment. This new volume deals with a host of important topics in environmental chemistry, such as pesticide-related illnesses in humans and plants, the effects of litterfall in the soil of tropical forests, toxicants in various bodies of water, and much more.

This book highlights the relevant and timely global change movement: green entrepreneurship. Presented in this book is relevant literature and academic knowledge. The book is expected to support in creating more green entrepreneurship initiatives in collaboration with the UN Sustainable Development Goals.
