The Anthropocene is the "age of human influence", an epoch well known for its urban impact. More than half of all people already live in cities, and this proportion is expected to rise to almost 70 percent by 2050. Like other species in urban areas, bats must contend with the pressures of profound and irreversible land cover change and overcome certain unique challenges, such as the high density of roads, lights, glass, and free-ranging domestic animals. Research on urban bats in recent decades indicates that when it comes to urban life, some bats are synanthropes. In other words, although most species of bats are negatively impacted by urbanisation, many appear to not only succeed, but also thrive in cities and towns. This observation has inspired interesting questions about bats in relation to urbanisation. Which traits and behaviours equip bats for urban success? What features of urban areas increase the likelihood that bats will successfully persist there or even colonize new areas? And how does the success of urban bats affect co-habiting humans? Our book explores the interactions between bats and urban environments through case studies and reviews. Understanding how different species interact with urban environments can reveal potential opportunities to mitigate urban threats to bats and threats posed by bats to other urban organisms, including humans. With this book, we thus aspire to provide a knowledge base to help guide current and future efforts to conserve bats.

17 van ons land se voorste boskundiges skryf oor die Bosveld se bewaring en bestuur, die geologie en grond, veld en plante, houtsoorte en ouderdomme van bome, oorlewing en veldgebruik in historiese tye, hedendaagse toerisme en wat dit sou behels om ’n plaas hier te koop.

In die volksmond verwys ‘bos’ na ’n houtagtigheid wat in samestelling, digtheid en hoogte verskil. Dit is ’n plek waar die lewensiklusse van sowat 5 700 plantsoorte bydra tot die polsende ritme en dinamiek van soet-, suur-, gemengde of dorre bosveld. ’n Anderhalf miljoen besoekers put jaarliks enorme plesier uit hierdie kosbare bioskat, maar dit is besig om vinnig te verarm weens die druk van menslike aktiwiteite en wanbestuur. Die benutting daarvan moet dringend met meer sensitiwiteit en kundigheid benader word. Om hierdie ideaal groter momentum te gee, deel 17 van ons land se voorste boskundiges hul kennis op ’n maklik verstaanbare en kleurvolle wyse – wonderlike leesstof vir die bewaarder, boer, student en elke bosliefhebber.

Hierdie bondige kroniek vertel van die Bosveld se bewaring en bestuur, die geologie en die grond, die veld en die plante, van houtsoorte en die ouderdomme van bome, van oorlewing en van veldgebruik in historiese tye, van hedendaagse toerisme en wat dit sou behels om ’n plaas hier te koop.

Human exploitation of other mammals has passed through three histori cal phases, distinct in their ecological significance though overlapping in time. Initially, Homo sapiens was a predator, particularly of herbivores but also of fur-bearing predators. From about 11 000 years ago, goats and sheep were domesticated in the Middle East, rapidly replacing gazelles and other game as the principal source of meat. The principal crops, including wheat and barley, were taken into agriculture at about the same time, and the resulting Neolithic farming culture spread slowly from there over the subsequent 10 500 years. In a few places such as Mexico, Peru and China, this Middle Eastern culture met and merged with agricultural traditions that had made a similar but independent transition. These agricultural traditions provided the essential support for the industrial revolution, and for a third phase of industrial exploita tion of mammals. In this chapter, these themes are drawn out and their ecological signifi cance is investigated. Some of the impacts of humans on other mammals require consideration on a world-wide basis, but the chapter concen trates, parochially, on Great Britain. What have been the ecological consequences of our exploitation of other mammals? 2. 2 HISTORICAL PHASES OF EXPLOITATION 2. 2. 1 Predatory man Our nearest relatives - chimpanzees, orang utans and gorillas - are essentially forest species, deriving most of their diet from the fruits of forest trees and the shoots and leaves of plants."

Operations Research Management Science approaches have helped people for the last 40 years to understand the complex functioning of the systems based upon natural resources, as well as to manage natural resources in the most efficient manner. The areas usually viewed within the natural resources field are: agriculture, fisheries, forestry, and mining and water resources. All of these areas share the common problem of optimally allocating scarcity over a period of time. The scale of time or length of the planning horizon differs from one area to another. We have almost a continuous renewal in the case of the fisheries, periodic cycles in the case of agriculture and forestry and enormous periods of time much beyond the human perception in the case of mining resources. But in all the cases, the critical issue is to obtain an efficient use of the resource along its planned time horizon.

Another element of connection among the different natural resources is due to the interaction between the use of the resource and the environmental impact caused by its extraction or harvest. This type of interaction implies additional complexities in the underlying decision-making process, making the use of OR/MS tools especially relevant.

HANDBOOK OF OPERATIONS RESEARCH IN NATURAL RESOURCES will be the first systematic handbook treatment of quantitative modeling natural resource problems, their allocated efficient use, and societal and economic impact. AndrA(c)s Weintraub is the very top person in Natural Resource research. Moreover, he has an international reputation in OR and a former president of the International Federation of Operational Research Societies (IFORS). He has selectedco-editors who are at the top of the sub-fields in natural resources: agriculture, fisheries, forestry, and mining. The book will cover these areas in terms with contributions from researchers on modeling natural research problems, quantifying data, developing algorithms, and discussing the benefits of research implementations. The handbook will include tutorial contributions when necessary. Throughout the book, technological advances and algorithmic developments that have been driven by natural resource problems will be called out and discussed.

The effects of disturbed ecosystems, from devastating algal blooms to the loss of whale populations, have demonstrated the vulnerability of the oceans¿ biodiversity. Conservation of marine systems requires knowledge from many different fields in order to understand the complex interactions that threaten those systems. Dynamic Modeling for Marine Conservation provides a method of learning how these systems function, determining how natural and human actions have put them in peril and how we can best influence the marine world in order to maintain biodiversity. The difficulties of research and experimentation in the oceans make computer modeling particularly helpful for marine conservation. Modeling also enables scientists to communicate their findings with managers and others concerned with putting their ideas into practice. The book will demonstrate dynamic modeling through the use of the STELLA modeling program and case studies from marine conservation. After a section devoted to the concepts and tools needed to model marine systems, each chapter introduces background information about a key topic in marine conservation, presents an appropriate model, and discusses the results and implications. Contributors bring a wide range of expertise and experience to a selection of models relevant to real-world conservation problems. All models and a run-time version of the STELLA software are included with the book on a CD-ROM, which is compatible with both Macintosh and Window platforms.

This book discusses recent developments in the study of chemical processes and equilibria in the marine environment and in the air/water and water/sediment interfaces. The chemical cycle of carbon as well as the effect of organic substances on the speciation and distribution of inorganic and organometallic substances are extensively discussed. Much of the recent progress in the area is the direct result of advanced analytical technologies and chemometric applications which are highlighted in the book.

In Underland, Robert Macfarlane delivers an epic exploration of the Earth's underworlds as they exist in myth, literature, memory, and the land itself. Traveling through the dizzying expanse of geologic time-from prehistoric art in Norwegian sea caves, to the blue depths of the Greenland ice cap, to a deep-sunk "hiding place" where nuclear waste will be stored for 100,000 years to come-Underland takes us on an extraordinary journey into our relationship with darkness, burial, and what lies beneath the surface of both place and mind. Global in its geography and written with great lyricism, Underland speaks powerfully to our present moment. At once ancient and urgent, this is a book that will change the way you see the world.

National institutions involved in environmental policy planning respond more to the accommodation of special interests, whether vested, parochial, or societal, than to the realities of technological advances. This situation, combined with the added problem of widespread scientific illiteracy, makes the formulation of effective environmental policy a very difficult task to accomplish.

Our politico-legal system and relationships among science, scientists, and society are explored here with specific attention to issues arising from pharmaceutical innovation and biotechnology. The identification of the resultant dilemmas reveal disenfranchisement and point to possible means of reform. Howell focuses on the need for multilateral responsibility for communication to improve the accommodation of science in policy. A truly multidisciplinary study, this book is for environmental planners as well as the interested public.

Environmental concerns are on the corporate agenda, and companies are searching for effective managerial strategies. Multinational corporations command huge financial resources and technical skills, and their actions toward the environment can have a profound impact. Drawing detailed examples from major multinational companies, this book provides a wealth of practical insight on how companies approach the difficult task of responding to an increasing variety of environmental challenges. The authors identify several specific programs being developed and implemented by corporations to establish accountability for environment, health and safety and to integrate environmental concerns throughout the corporate decision making process.

The material in this work is drawn from extensive interviews conducted in U.S.-based companies, and examinations of production facilities in developed and developing countries. In addition, results of a survey on corporate environment, health and safety practices are woven into the analysis. Although they note that there are inadequacies in some corporate responses to environmental challenges, the authors contend that improved practice will result from actions on the part of government and universities, as well as companies themselves. This book will help decision makers review their environmental programs and develop sound strategies to overcome the corporate environmental anxiety that, We know we're out of compliance somewhere in the world all of the time.

This book, the result of the author's experience in psychology and forestry studies, studies the relation between these two seemingly different disciplines. The author indicates how human actions and programs affect a range of threatened or endangered situations ranging from forests and species of animals to our own traditional values and cultural groups. Sustainers, the persons who advocate and support sustainability, possess or must come to possess certain characteristics that are shown to be renunciation, knowledge, attitude, controllability, and patterning. This book seeks to discover and advocates how and why those attributes must be strengthened if we are to sustain our environment and ourselves.

Deciding what user impacts are natural or unnatural has inspired much debate. Biophysically, moose cause similar kinds of soil and vegetation impacts as hikers. Yet moose are the sign of nature while hikers are the sign of damage. The field of outdoor recreation is beset with paradoxes, and this book presents a unique, alternative framework to address these dilemmas. Examining outdoor recreation through the lens of ecological theory, Ryan draws from theorists such as Foucault, Derrida and Latour. The book explores minimum impact strategies designed to protect and enhance ecological integrity, but that also require a disturbing amount of policing of users, which runs counter to the freedom users seek. Recent ecological theory suggests that outdoor recreation's view of nature as balanced when impacts are removed is outdated and incorrect. What is needed, and indeed Ryan presents, is a paradoxical and ecological view of humans as neither natural nor unnatural, a view that embraces some traces in nature.

In the first study to examine F. W. J. Schelling's political thought, Velimir Stojkovski not only unearths a neglected dimension of the influential thinker's philosophy but further shows what it can teach us about our ethical and political responsibilities today. Unlike Hegel or Fichte, Schelling never wrote a political treatise. Yet by reconstructing the portions of such works as The New Deductions of Natural Right that deal explicitly with the political and by thematically rethinking parts of his writings that have a clear repercussion on politics - in particular those on nature, freedom and religion - this book reveals the centrality of politics to his oeuvre. Revisiting his corpus in this way, Stojkovski uncovers a number of ways we can learn from Schelling and his reception. He examines how Schelling's views on nature can clarify our moral and political obligations to the non-human world and further demonstrates how the separation of ontology as first philosophy from the ethico-political has resulted in a fragmented view of the status of the political subject and thus the body politic. Forcefully renouncing this fragmentation, Stojkovski explores how the same divide has contributed to the ongoing political turmoil in Europe and America. Combining an exploration of German Idealism with contemporary concerns, this is an essential study that will introduce readers to a new Schelling: a political thinker for the 21st century.

This book presents a comprehensive overview and analysis of mangrove ecological processes, structure, and function at the local, biogeographic, and global scales and how these properties interact to provide key ecosystem services to society. The analysis is based on an international collaborative effort that focuses on regions and countries holding the largest mangrove resources and encompasses the major biogeographic and socio-economic settings of mangrove distribution. Given the economic and ecological importance of mangrove wetlands at the global scale, the chapters aim to integrate ecological and socio-economic perspectives on mangrove function and management using a system-level hierarchical analysis framework. The book explores the nexus between mangrove ecology and the capacity for ecosystem services, with an emphasis on thresholds, multiple stressors, and local conditions that determine this capacity. The interdisciplinary approach and illustrative study cases included in the book will provide valuable resources in data, information, and knowledge about the current status of one of the most productive coastal ecosystem in the world.

This book explains why international negotiations have not produced a sustainable solution to tropical rainforest degradation. Using an innovative, critical approach to international regimes, the author analyzes the structure and operation of the International Tropical Timber Organization (ITTO). He shows how the timber industry and producing- and consuming-country governments created a blocking alliance that favored developmentalist interests and ideas. The ITTO bolstered this alliance by permitting environmentalists merely to voice, but not negotiate, their concerns.

The authors of Re-Indigenizing Ecological Consciousness and the Interconnectedness to Indigenous Identities share the diversity and complexities of the Indigenous context of worldviews, examining relationships between humans and other living beings within an eco-conscious lens. Michelle Montgomery's edited volume shows that we belong not only to a human community, but to a community of all nature as well. The contributors demonstrate that the reciprocity of Indigenous knowledges is inclusive and represents worldviews for regenerative solutions and the need to realign our view of the environment as a "who" rather than an "it." This reciprocity is intertwined as an obligation of environmental ethics to acknowledge the attributes of Indigenous knowledges as not merely a body of knowledge but as multiple layers or levels of placed-based knowledges, identities, and lived experiences.

A Philosophical Journey into the Anthropocene: Discovering Terra Incognita presents the Anthropocene as more than a geological epoch, but rather it as the potential metarecit of our age and the most faithful expression of the current Zeitgeist. Insofar as the Anthropocene establishes that the human agency as technological omni-power represents a "global geophysical force" capable of altering the destiny of the Earth system, the coming of this new epoch shows that technology now embodies the subject of both history and nature. This technology achieves the status of an integral epochal phenomenon: the new environment for human life. Agostino Cera traces how the "technisches Zeitalter" (age of technology) outlined by twentieth-century philosophical thought emerged out of the Anthropocene and suggests that a more appropriate name for this planetary framework Technocene. The book develops along four basic directions: epistemological, ontological, anthropological, and ethical. It argues that the Anthropocene is something radically new, a terra incognita or an "epistemic hyperobject with a (geo-)historical barycenter," giving rise to: 1) an unprecedented form of reification of nature ("pet-ification of nature"); 2) an unexpected version of anthropocentrism ("Aidosean Prometheanism"), and 3) an unpredictable ethical paradox ("paradox of omni-responsibility").

This book owes a great deal to the outstanding universal value of the natural heritage of Hubei Shennongjia, which offers an outstanding example of the ongoing ecological processes occurring in the development of intact subtropical mixed broad-leaved evergreen and deciduous forests in the northern hemisphere. The book demonstrates the value from the typical example of mountain altitudinal biological zones in the Oriental Deciduous Forest Biogeographical Province, and the vital origin location for global temperate flora, harboring the highest concentration of global temperate genera. Moreover, the heritage value in exceptional biodiversity and key habitat for numerous relic, rare, endangered, endemic, and type specimen species are presented. The richness of deciduous woody species in Shennongjia is the highest in the world.

A riveting portrait of the cultural struggles and political conflicts of proposed copper-nickel mines in Minnesota's Iron Range On an unseasonably warm October afternoon in Saint Paul, hundreds of people gathered to protest the construction of a proposed copper-nickel mine in the rural northern part of their state. The crowd eagerly listened to speeches on how the project would bring long-term risks and potentially pollute the drinking water for current and future generations. A year later, another proposed mining project became the subject of a public hearing in a small town near the proposed site. But this time, local politicians and union leaders praised the mine proposal as an asset that would strengthen working-class communities in Minnesota. In many rural American communities, there is profound tension around the preservation and protection of wilderness and the need to promote and profit from natural resources. In Mining the Heartland, Erik Kojola looks at both sides of these populist movements and presents a thoughtful account of how such political struggles play out. Drawing on over a hundred ethnographic interviews with people of the region, from members of labor unions to local residents to scientists, Kojola is able to bring this complex struggle over mining to life. Focusing on both pro- and anti-mining groups, he expands upon what this conflict reveals about the way whiteness and masculinity operate among urban and rural residents, and the different ways in which class, race, and gender shape how people relate to the land. Mining the Heartland shows the negotiation and conflict between two central aspects of the state's culture and economy: outdoor recreation in the Land of Ten Thousand Lakes and the lucrative mining of the Iron Range.

An environmental historian delves into the history, science, and philosophy of a paradoxical pursuit: the century-old quest to design natural places and create wild species. Environmental restoration is a global pursuit and a major political concern. Governments, nonprofits, private corporations, and other institutions spend billions of dollars each year to remove invasive species, build wetlands, and reintroduce species driven from their habitats. But restoration has not always been so intensively practiced. It began as the pastime of a few wildflower enthusiasts and the first practitioners of the new scientific discipline of ecology. Restoration has been a touchstone of US environmentalism since the beginning of the twentieth century. Diverging from popular ideas about preservation, which romanticized nature as an Eden to be left untouched by human hands, and conservation, the managed use of natural resources, restoration emerged as a "third way." Restorationists grappled with the deepest puzzles of human care for life on earth: How to intervene in nature for nature's own sake? What are the natural baselines that humans should aim to restore? Is it possible to design nature without destroying wildness? Laura J. Martin shows how, over time, amateur and professional ecologists, interest groups, and government agencies coalesced around a mode of environmental management that sought to respect the world-making, and even the decision-making, of other species. At the same time, restoration science reshaped material environments in ways that powerfully influenced what we understand the wild to be. In Wild by Design, restoration's past provides vital knowledge for climate change policy. But Martin also offers something more-a meditation on what it means to be wild and a call for ecological restoration that is socially just.
