Originally published in 1972, Homo Sapiens examines how humans emerged from among the millions of other species and achieved our unique position within the animal kingdom. The book examines what direction future evolution will take and what may be regarded as the 'meaning' of human existence. It stipulates that these are the questions for which no real basis of discussion existed before the 20th century, and at the time of publication, some were still without a definite answer. The book sets out analyse these questions and the continuing debate that has arisen from their study. This is an account of the uniqueness of man in the animal kingdom, how this uniqueness arose during evolution, and what traces of it can be detected in animals other than man. The book describes the mental and physical evolution of man, from his earliest ancestors to the present day. He also gives an account of man's cultural development seeking to establish that there is an underlying principal of cultural evolution, a principle that has been denied by many historians. Later chapters deal with the future and with possible forecasts of mankind's further physical, intellectual and cultural evolution.
Swathes of the human world are covered in ornamental grass lawns; they are the single most commonly encountered horticultural feature on the planet. Unfortunately, they are now often viewed as resource-draining green deserts due to the lack of plant and animal diversity, the need for frequent mowing and watering, and addition of lawn greening products to keep them looking at their best. It is a venerable horticultural feature that is essentially frozen in time, and with few alternatives to whet the appetite, the lawn has languished in its current grass-only format for decades. Until now. Tapestry lawns are a new, practically researched and timely development of the ornamental lawn format that integrates both horticultural practice and ecological science and re-determines the potential of a lawn. Mown barely a handful of times a year and with no need for fertilisers or scarifying, tapestry lawns are substantially richer in their diversity of plant and animal life compared to traditional grass-only lawns and see the return of flowers and colour to a format from which they are usually purposefully excluded. Tapestry Lawns: Freed from Grass and Full of Flowers traces the changes in the lawn format from its origins to the modern day and offers information on how and why the tapestry lawn construct is now achievable. It provides guidance on how to create and maintain a tapestry lawn of your own and champions the potential benefits for wildlife that can follow. Features Accessible and informative to all types of readers from academic to amateur Includes a refined and tested set of useful tapestry lawn plants Contains step-by-step instructions for creation and management methods of grass-free lawns Illustrated in full colour If you have ever thought about mowing your lawn much less, making it much more colourful and wildlife friendly, then this book will inform and guide you to create a perfect, grass-free lawn.
This open access book features essays written by philosophers, biologists, ecologists and conservation scientists facing the current biodiversity crisis. Despite increasing communication, accelerating policy and management responses, and notwithstanding improving ecosystem assessment and endangered species knowledge, conserving biodiversity continues to be more a concern than an accomplished task. Why is it so?The overexploitation of natural resources by our species is a frequently recognised factor, while the short-term economic interests of governments and stakeholders typically clash with the burdens that implementing conservation actions imply. But this is not the whole story. This book develops a different perspective on the problem by exploring the conceptual challenges and practical defiance posed by conserving biodiversity, namely: on the one hand, the difficulties in defining what biodiversity is and characterizing that "thing" to which the word 'biodiversity' refers to; on the other hand, the reasons why assessing biodiversity and putting in place effective conservation actions is arduous.
This title was first published in 2000: An edited collection based on a workshop which explored the biological, social, ethical, economic and political pressures underlying the present perceived loss of biodiversity. It brings together philosophers, economists, biologists and others whose fields deal with the conservation of nature's diversity, and with the preservation and protection of species and ecosystems.
This book describes the reasons humankind may be facing its last moments on Planet Earth. Darwin marked the path of species evolution, modification, and extinction. Following Darwin's trajectory of evolution, the author reveals how human-made technologies have had a devastating impact on Earth's biosphere, signaling the continuing disappearance of landscapes and the decline of species life.
Forestry today, like many other sectors that traditionally rely on material goods, faces significant global drivers of societal change that are less often addressed than the environmental concerns commonly in the spotlight of scientific, political, and news media. There are three major interconnected issues that are challenging forestry at its foundation: urbanization, tertiarization, and globalization. These issues are at the core of this book. The urbanization of society, a process in development from the first steps of industrialization, is particularly significant today with the predominance and quick growth rate of the world's urban population. Ongoing urbanization is creating new perspectives on forestry, inducing changes in its social representation, and changing lifestyles and practices with a tendency toward dematerialization. The process of urbanization is also creating a disconnect and in some ways is leaving behind rurality, the sector of society where forestry has traditionally developed and taken place over centuries. The second issue covered in this book is the tertiarization of the economy. In society today, the sector of services largely dominates the economy and occupies the major part of the world's active population. This ongoing process modifies professional modalities and ways of life and opens new doors to forests through the immaterial goods they provide. It also profoundly changes the framework, rules, processes, means of production, exchanges between economic factors, and the processes of innovation. The third issue is undoubtedly globalization in its economic, political, and social components. Whether it's through bridging distances, crossing borders, accelerating changes, standardizing practices, leveling hierarchical structures, or pushing for interdependence, globalization impacts everyone, everywhere in multiple ways. Forestry is no exception. Forestry in the Midst of Global Changes focuses on these global drivers of change from the perspective of their relationships with how society functions. By analyzing them in depth through multidisciplinary, interdisciplinary, and even transdisciplinary approaches, this book is helping to design the forestry of tomorrow.
Bees are critically important for ecosystem function and biodiversity maintenance through their pollinating activity. Unfortunately, bee populations are faced with many threats, and evidence of a massive global pollination crisis is steadily growing. As a result, there is a need to understand and, ideally, predict how bees respond to pollution disturbance, to the changes over landscape gradients, and how their responses can vary in different habitats, which are influenced to different degrees by human activities. Modeling approaches are useful to simulate the behavior of whole population dynamics as well as to focus on important phenomena detrimental to bee-life history traits. They also allow simulation of how a disease or a pesticide can impact the survival and growth of a bee population. In Silico Bees provides a collection of computational methods to those primarily interested in the study of the ecology, ethology, and ecotoxicology of bees. The book presents different cases studies to enable readers to understand the significance and also the limitations of models in theoretical and applied bee research. The text covers modeling of honey bee society organization, infectious diseases in colonies, pesticide toxicity, chemical contamination of the hive, and more. Written by an international team of scientists, this book is of primary interest to those whose research or professional activity is directly concerned with the study of bees. It is also intended to provide graduate and post-graduate students with a clear and accessible text covering the main types of modeling approaches that can be used in terrestrial ecology and ecotoxicology.
Population genomics has provided unprecedented opportunities to unravel the mysteries of marine organisms in the oceans' depths. The world's oceans, which make up 70% of our planet, encompass diverse habitats and host numerous unexplored populations and species. Population genomics studies of marine organisms are rapidly emerging and have the potential to transform our understanding of marine populations, species, and ecosystems, providing insights into how these organisms are evolving and how they respond to different stimuli and environments. This knowledge is critical for understanding the fundamental aspects of marine life, how marine organisms will respond to environmental changes, and how we can better protect and preserve marine biodiversity and resources. This book brings together leading experts in the field to address critical aspects of fundamental and applied research in marine species and share their research and insights crucial for understanding marine ecosystem diversity and function. It also discusses the challenges, opportunities and future perspectives of marine population genomics.
Out-migration might decrease the pressure of population on the environment, but what happens to the communities that manage the local environment when they are weakened by the absence of their members? In an era where community-based natural resource management has emerged as a key hope for sustainable development, this is a crucial question. Building on over a decade of empirical work conducted in Oaxaca, Mexico, Communities Surviving Migration identifies how out-migration can impact rural communities in strongholds of biocultural diversity. It reflects on the possibilities of community self-governance and survival in the likely future of limited additional migration and steady - but low - rural populations, and what different scenarios imply for environmental governance and biodiversity conservation. In this way, the book adds a critical cultural component to the understanding of migration-environment linkages, specifically with respect to environmental change in migrant-sending regions. Responding to the call for more detailed analyses and reporting on migration and environmental change, especially in contexts where rural communities, livelihoods and biodiversity are interconnected, this volume will be of interest to students and scholars of environmental migration, development studies, population geography, and Latin American studies.
This book is a product of the TEEB study (The Economics of Ecosystems and Biodiversity). It provides important evidence of growing corporate concern about biodiversity loss and offers examples of how leading companies are taking action to conserve biodiversity and to restore ecosystems. This book reviews indicators and drivers of biodiversity loss and ecosystem decline, and shows how these present both risks and opportunities to all businesses. It examines the changing preferences of consumers for nature-friendly products and services, and offers examples of how companies are responding. The book also describes recent initiatives to enable businesses to measure, value and report their impacts and dependencies on biodiversity and ecosystem services. The authors review a range of practical tools to manage biodiversity risks in business, with examples of how companies are using these tools to reduce costs, protect their brands and deliver real business value. The book also explores the emergence of new business models that deliver biodiversity benefits and ecosystem services on a commercial basis, the policy enabling frameworks needed to stimulate investment and entrepreneurship to realize such opportunities, and the obstacles that must be overcome. The book further examines how businesses can align their actions in relation to biodiversity and ecosystem services with other corporate responsibility initiatives, including community engagement and poverty reduction. Finally, the book concludes with a summary and recommendations for action.
The field of ecohydraulics integrates hydrodynamic and eco-dynamic processes. While hydrodynamic processes are usually well described by partial differential equations (PDE's) based on physical conservation principles, ecosystem dynamics often involve specific interactions at the local scale. Because of this, Cellular Automata (CA) are a viable paradigm in ecosystem modelling. All cells in a CA system update their states synchronously at discrete steps according to simple local rules. The classical CA configuration consists of uniformly distributed cells on a structured grid. But in the field of hydrodynamics, the use of unstructured grids has become more and more popular due to its flexibility to handle arbitrary geometries. The main objective of this research is to identify whether the CA paradigm can be extended to unstructured grids. To that end the concept of Unstructured Cellular Automata (UCA) is developed and various UCA configurations are explored and their performance investigated. The influence of cell size was analyzed in analogy with the Finite Volume Method. A characteristic parameter -min distance of UCA- was put forward and tested by numerical experiments. Special attention was paid to exploring the analogies and differences between the discrete CA paradigm and discrete numerical approximations for solving PDE's. The practical applicability of UCA in ecohydraulics modelling is explored through a number of case studies and compared with field measurements.
Structured in the form of a dichotomous key, comparable to those widely used in botany, the mineral key provides an efficient and systematic approach to identifying rock-forming minerals in thin-section. This unique approach covers 150 plus of the most commonly encountered rock-forming minerals, plus a few rarer but noteworthy ones. Illustrated in full colour, with 330 plus high quality mineral photomicrographs from a worldwide collection of igneous, metamorphic, and sedimentary rocks, it also provides a comprehensive atlas of rock-forming minerals in thin-section. Commencing with a brief introduction to mineral systems, and the properties of minerals in plane-polarised and cross-polarised light, the mineral key also includes line drawings, tables of mineral properties and an interference colour chart, to further aid mineral identification. To minimise the chance of misidentification, and enable less experienced petrologists to use the key with confidence, the key has been arranged to prioritise those properties that are most easily recognised. Designed for simplicity and ease of use, it is primarily aimed at undergraduate and postgraduate students of mineralogy and petrology, but should also provide a valuable source of reference for all practising geologists dealing with rock thin sections and their interpretation.
This book is the most thorough exploration to date of the many ways in which a wild creature has been absorbed, reimagined and represented across the ages in all of the major art forms. The authors consider not only how the identity of sharks in the natural environment became incorporated into a cultural environment but also how sharks came to be considered the most feared creatures in the open oceans as a consequence of this incorporation. Yet sharks are especially important in helping to maintain a balance that is essential to the health of the oceans. The book begins with a treatment of the three sharks at the top of global shark-attack files from scientific, economic and environmental perspectives. Subsequent chapters engage with cultural representations of sharks in poetry, drama, art, novels, screenplay adaptations and films. Through an exploration of the ways in which sharks have been represented in human culture through the centuries, this book alerts the global community to the importance of sharks as a common cultural heritage. It aims to change perceptions of sharks so that they can become more revered than feared. The authors of this book argue that an increased understanding of sharks should lead to the development of better strategies for shark and human interactions. This book will be of great interest to researchers and students of the Environmental Humanities, Cultural History and the Arts. It is also excellent supplementary reading for courses in Zoology and Marine Science.
Today, problems such as deforestation, biodiversity loss and illegal logging have provoked various policy responses that are often referred to as forest and nature governance. In its broadest interpretation, governance is about the many ways in which public and private actors from the state, market and/or civil society govern public issues at multiple scales. This book takes a fresh perspective on the study of forest and nature governance. Departing from 'practice theory', and building upon scholars like Giddens, Bourdieu, Reckwitz, Schatzki and Callon, it seeks to move beyond established understandings of institutions, actors, and knowledge. In so doing, it not only presents an innovative conceptual and methodological framework for a practice based approach, but also rich case studies and ethnographies. Finally, this book is about how actors involved in governance talk about and work with trees, forests, biodiversity, wildlife, and so on, while acting upon forest policies, environmental discourses, codes of conduct, or scientific insights.
This book provides insights into various aspects of medicinal plant-associated microbes, known to be a unique source of biological active compounds, including their biotechnological uses and their potential in pharmaceutical, agricultural and industrial applications. Featuring review papers and original research by leading experts in the field, it discusses medicinal plants and their interactions with the environment; medicinal plants as a source of biologically active compounds; medicinal plant-associated microbes (diversity and metabolites); their pharmaceutical, agricultural and industrial applications as well as their potential applications as plant growth stimulators and biocontrol agents. As such the book offers a valuable, up-to-date overview of the current research on medicinal plants, their ecology, biochemistry and associated biomes.
This volume provides a reference textbook and comprehensive compilation of multifaceted perspectives on the legal issues arising from the conservation and exploitation of non-human biological resources. Contributors include leading academics, policy-makers and practitioners reviewing a range of socio-legal issues concerning the relationships between humankind and the natural world. The Routledge Handbook of Biodiversity and the Law includes chapters on fundamental and cutting-edge issues, including discussion of major legal instruments such as the Convention on Biological Diversity and the Nagoya Protocol. The book is divided into six distinct parts based around the major objectives which have emerged from legal frameworks concerned with protecting biodiversity. Following introductory chapters, Part II examines issues relating to conservation and sustainable use of biodiversity, with Part III focusing on access and benefit-sharing. Part IV discusses legal issues associated with the protection of traditional knowledge, cultural heritage and indigenous human rights. Parts V and VI focus on a selection of intellectual property issues connected to the commercial exploitation of biological resources, and analyse ethical issues, including viewpoints from economic, ethnobotanical, pharmaceutical and other scientific industry perspectives.
Wood-pastures are important elements of European cultural identity and have an exceptional ecological value, yet they are in decline all over Europe. The structure of wood-pastures is strongly influenced by grazing and multiple other land uses and by local and regional environmental conditions. This book examines the diverse expressions of wood-pastures across Europe. It provides a new perspective, using a social-ecological framework to explore social and ecological values, governing institutions, threats and conservation approaches. It explores the major drivers of decline, which are shown to be related to accelerated cultural, institutional and developmental changes occurring across Europe over the past century. Case studies are included from North-Western, Southern, and Eastern Europe. Written by renowned scholars and conservationists, the book contributes to developing better, locally adapted conservation policies and management approaches for wood-pastures.
Community forestry focuses on the link between forest resources and livelihoods and contributes to forest conservation and reforestation. It is widespread in Nepal, with a very high proportion of the rural population involved, and is widely recognized as one of the most successful examples of community forestry in Asia. Through a combination of literature reviews and original research, this volume explores key experiences and outcomes of community forestry in Nepal over the last four decades as a model for improving forest management and supporting local livelihoods. The book takes a critical approach, recognizing successes, especially in forest conservation and restoration, along with mixed outcomes in terms of poverty reduction and benefits to forest users. It recognizes the way that community forestry has continued to evolve to meet new challenges, including the global challenges of climate change, environmental degradation and conservation, as well as national demographic and social changes due to large-scale labour migration and the growing remittance economy. In addition to examining the changes and responses, the book explores ways that community forestry in Nepal might move forward. Lessons from Nepal have relevance to community forestry and community-based approaches to natural resource management around the world that are also experiencing global pressures and opportunities.
The first edition of this incisive text on the problems of drought and famine facing Africa won worldwide critical acclaim. Revised with a new introduction, Lloyd Timberlake's bestselling study is invaluable reading for anyone interested in Africa.
"RFF's Roger Sedjo and his colleagues discuss initiatives designed to promote and enhance sustainable forestry in temperate countries. While concerns about tropical deforestation are considerable, temperate forests account for the vast majority of the world's roundwood production and most global trade in wood and paper. Improving forest sustainability in such regions is imperative, economically and environmentally. This book illustrates how far nations have progressed, and how far they still need to go, in that effort. The authors describe how temperate nations address forest sustainability, discussing recent developments affecting forestry and trade. Their compilation of international data on forest practices and regulation provides a useful comparative perspective. They analyze the effect of institutional changes (e.g., new laws) on land management. The volume assesses how national forestry industries are adapting to new laws and policies in the face of new realities in production and markets, particularly in the context of international trade and global competition. Country profiles provide details on sustainability policy and performance in eight timber-exporting or major wood-using temperate nations: the United States, Canada, Finland, Sweden, Germany, France, New Zealand, and Chile. The authors also assess how each nation would be affected by the application of various criteria for sustainability."
The Marcell Experimental Forest (MEF) in Minnesota serves as a living laboratory and provides scientists with a fundamental understanding of peatland hydrology, acid rain impacts, nutrient and carbon cycling, trace gas emissions, and controls on mercury transport in boreal watersheds. Its important role in scientific research continues to grow as the data gathered offers invaluable insight into environmental changes over the last century and goes far in answering many of today's pressing questions at landscape and global scales. Synthesizing five decades of research, Peatland Biogeochemistry and Watershed Hydrology at the Marcell Experimental Forest includes hundreds of research publications, dozens of graduate theses, and even some previously unpublished studies. Research at the MEF has been at the forefront of many scientific disciplines and these 15 chapters offer the depth and breadth of long-term studies on hydrology, biogeochemistry, ecology, and forest management on peatland watersheds at the MEF. Focusing on peatlands, lakes, and upland landscapes, the book begins with the pioneering research on hydrology done during the 1960s. It presents the innovative 1970's studies of atmospheric deposition; the 1980's research into nutrient cycles including carbon, nitrogen, and methane emissions; and the 1990's investigations into mercury deposition. The book concludes with a look at the latest and on-going studies such as this century's research into controls on methylmercury production and landscape-level carbon storage and cycling. Covering 50 years of research and written by a veritable who's who in peatland and forestry science, this important milestone in the collection of ecological data highlights bright prospects for future research, including the continuation of existing long-term measurements, the initiation of new monitoring programs, and plans for unprecedented studies on climate change.
Ever since Darwin, science has enshrined competition as biology's brutal architect. But this revelatory new book argues that our narrow view of evolution has caused us to ignore the generosity and cooperation that exist around us, from the soil to the sky. In Sweet in Tooth and Claw, Kristin Ohlson explores the subtle ways in which nature is in constant collaboration to the betterment of all species. From the bear that discards the remainders of his salmon dinner on the forest ground, to the bright coral reefs of Cuba, she shows readers not only the connectivity lying beneath the surface in natural ecosystems, but why it's vital for humans to incorporate that understanding into our interactions with nature, and also with each other. Much of the damage that humans have done to our natural environment stems from our ignorance of these dense webs of connection. As we struggle to cope with the environmental hazards that our behaviour has unleashed, it's more important than ever to understand nature's billions of cooperative interactions. This way, we can stop disrupting them and instead rely on them to renew ecosystems. In reporting from the frontlines of scientific research, regenerative agriculture, and urban conservation, Ohlson shows that a shift from focusing on competition to collaboration can heal not only our relationships with the natural world, but also with each other.
Freshwater ecosystems have the greatest species diversity per unit area and many endangered species. This book shows that, rather than being a marginal part of terrestrial protected area management, freshwater conservation is central to sustaining biodiversity. It focuses on better practices for conserving inland aquatic ecosystems in protected areas, including rivers, wetlands, peatlands, other freshwater and brackish ecosystems, and estuaries. The authors define inland aquatic ecosystems, showing just how diverse and widespread they are. They examine the principles and processes that are essential for the conservation of freshwater ecosystems and aquatic species. Major categories of threats to freshwater ecosystems and the flow-on implications for protected area design are described. Practical case studies are used to illustrate principles and practices applied around the world. Specific management needs of the main types of freshwater ecosystems are considered, as well as the management of freshwaters in the broader landscape, showing how natural resource governance processes can be harnessed to better manage freshwater biodiversity. The book offers commentary on how to adapt freshwater conservation practices to climate change and ends with an insightful synthesis.
This volume was developed from the proceedings of a symposium held in Miami Beach, at the 189th National Meeting of the American Chemical Society.It is the result of the combined efforts of many experts whose efforts have advanced our knowledge of the production, analysis, distribution, effects and control of chlorinated dioxins, dibenzofurans and related compounds.This is the third in a series of publications originating from current technology presented at national meetings of the American Chemical Society. Using this forum as a catalyst, researchers from all over the world came together to present and discuss their data and plan future work in this rapidly developing and sometimes highly emotional technical area.
Spellman's Standard Handbook for Wastewater Operators is a three-volume study guide and readily accessible source of information for review in preparing wastewater personnel for operator certification and licensure. These handbooks are resource manuals and troubleshooting guides that contain a compilation of wastewater treatment information, data, operational material, process control procedures and problem solving, safety and health information, new trends in wastewater treatment administration and technology, and numerous sample problem-solving practice sets, many based on actual tests. The Handbook volumes review the wastewater operator's job-related knowledge as job requirements identified by the examination developers as essential for a minimally competent Class IV through Class I or Grade I through Grade V wastewater treatment plant operator. Every attempt has been made to make the three Handbook volumes as comprehensive as possible, while maintaining their compact, practical format. |
