Aldo Leopold: A Sand County Almanac & Other Writings on Conservation and Ecology
by Aldo Leopold Curt MeineSince his death in 1948, Aldo Leopold has been increasingly recognized as one of the indispensable figures of American environmentalism. A pioneering forester, sportsman, wildlife manager, and ecologist, he was also a gifted writer whose farsighted land ethic is proving increasingly relevant in our own time. Now, Leopold's essential contributions to our literature--some hard-to-find or previously unpublished--are gathered in a single volume for the first time. Here is his classic A Sand County Almanac, hailed--with Thoreau's Walden and Carson's Silent Spring--as one of the main literary influences on the modern environmental movement. Published in 1949, it is still astonishing today: a vivid, firsthand, philosophical tour de force. Along with Sand County are more than fifty articles, essays, and lectures exploring the new complexities of ecological science and what we would now call environmental ethics. Leopold's sharp-eyed, often humorous journals are illustrated here for the first time with his original photographs, drawings, and maps. Also unique to this collection is a selection of over 100 letters, most of them never before published, tracing his personal and professional evolution and his efforts to foster in others the love and sense of responsibility he felt for the land.
Aldo Leopold's Odyssey: Rediscovering the Author of A Sand County Almanac
by Julianne Lutz NewtonA household icon of the environmental movement, Aldo Leopold (1887-1948) may be the most quoted conservationist in history. A Sand County Almanac has sold millions of copies and Leopold's writings are venerated for their perceptions about land and how people might live in concert with the whole community of life. But who is the man behind the words? How did he arrive at his profound and poetic insights, inspiring generations of environmentalists? Building on past scholarship and a fresh study of Leopold's unpublished archival materials, Julianne Lutz Newton retraces the intellectual journey generated by such passion and intelligence. Aldo Leopold's Odyssey illuminates his lifelong quest for answers to a fundamental issue: how can people live prosperously on the land and keep it healthy, too? Leopold's journey took him from Iowa to Yale to the Southwest to Wisconsin, with fascinating stops along the way to probe the causes of early land settlement failures, contribute to the emerging science of ecology, and craft a new vision for land use. More than a biography, this articulate volume is a guide to one man's intellectual growth, and an inspirational resource for anyone pondering the relationships between people and the land.
Aldo Leopold's Odyssey, Tenth Anniversary Edition: Rediscovering the Author of A Sand County Almanac
by Julianne Lutz WarrenIn 2006, Julianne Lutz Warren(néeNewton) asked readers to rediscover one of history's most renowned conservationists. Aldo Leopold's Odyssey was hailed by The New York Times as a "biography of ideas," making "us feel the loss of what might have followed A Sand County Almanac by showing us in authoritative detail what led up to it. " Warren's astute narrative quickly became an essential part of the Leopold canon, introducing new readers to the father of wildlife ecology and offering a fresh perspective to even the most seasoned scholars. A decade later, as our very concept of wilderness is changing, Warren frames Leopold's work in the context of the Anthropocene. With a new preface and foreword by Bill McKibben, the book underscores the ever-growing importance of Leopold's ideas in an increasingly human-dominated landscape. Drawing on unpublished archives, Warren traces Leopold's quest to define and preserve land health. Leopold's journey took him from Iowa to Yale to the Southwest to Wisconsin, with fascinating stops along the way to probe the causes of early land settlement failures, contribute to the emerging science of ecology, and craft a new vision for land use. Leopold's life was dedicated to one fundamental dilemma: how can people live prosperously on the land and keep it healthy, too? For anyone compelled by this question, the Tenth Anniversary Edition of Aldo Leopold's Odyssey offers insight and inspiration.
¡Alerta!: Engineering on Shaky Ground
by Elizabeth ReddyA lively account of a controversial technology developed to mitigate earthquake risk and change how we live with threatening environments.The Sistema de Alerta Sísmica Mexicano is the world&’s oldest public earthquake early warning system. Given the unpredictability of earthquakes, the technology was designed to give the people of Mexico City more than a minute to prepare before the next big quake hits. How does this kind of environmental monitoring technology get built in the first place? How does its life-saving promise align with reality? And who shapes modern risk mitigation? In ¡Alerta!, Elizabeth Reddy surveys this innovation to shed light on what it means to imagine a world where sirens could sound out an ¡alerta sísmica! at any moment—and what it would be like to live in such a world.Proponents of earthquake early warnings have long held that the technology can save lives and limit economic losses. Drawing on ethnographic fieldwork and archival data, Reddy conducts a thorough, qualitative analysis of these claims and considers the requirements and uses of the alert system. She embeds her study in a rich narrative of the engineers who designed the system in conjunction with contingent political and environmental conditions. The result demonstrates how addressing earthquake dangers is no small task: it means trying to change relationships between the environment, society, and technology. Doing so, she critiques universalist and techno-centric approaches to hazard risk mitigation and celebrates the potential of contextually appropriate and broadly supported efforts.¡Alerta! takes readers on a vivid journey into the world of Mexican earthquake risk mitigation, with critical insights for anthropologists and science and technology studies scholars, as well as specialists in the geosciences, engineering, and emergency management.
Alexander von Humboldt: Multiperspective Approaches
by Gregor C. Falk Manfred R. Strecker Simon SchneiderThis book aims to view and to understand Alexander von Humboldt from different perspectives and in varying disciplinary contexts. His contributions addressed numerous topics in the earth but also life sciences—spanning from geo-botany, climatology, paleontology, oceanography, mineralogy, resources, and hydrogeology to links between the environmental impact of humans, erosion, and climate change. From the very beginning, he paved the way for a modern, integrated earth system science approach to decipher, characterize, and model the different forcing factors and their feedback mechanisms. It becomes obvious that Humboldt’s holistic approach is far beyond simple description and empiric data collection. As documented and analyzed in the different texts of this volume, he combines observation and analysis with emotions and subjective perceptions in a very affectionate way. However, this publication does not intend to add another encyclopedic text compilation but to observe and critically analyze this unique personality´s relevance in a modern context, particularly in discussing environmental and social key issues in the twenty-first century.

An Alfred Russel Wallace Companion
by Charles H. SmithAlthough Alfred Russel Wallace (1823–1913) was one of the most famous scientists in the world at the time of his death at the age of ninety, today he is known to many as a kind of “almost-Darwin,” a secondary figure relegated to the footnotes of Darwin’s prodigious insights. But this diminution could hardly be less justified. Research into the life of this brilliant naturalist and social critic continues to produce new insights into his significance to history and his role in helping to shape modern thought. Wallace declared his eight years of exploration in southeast Asia to be “the central and controlling incident” of his life. As 2019 marks one hundred and fifty years since the publication of The Malay Archipelago, Wallace’s canonical work chronicling his epic voyage, this collaborative book gathers an interdisciplinary array of writers to celebrate Wallace’s remarkable life and diverse scholarly accomplishments. Wallace left school at the age of fourteen and was largely self-taught, a voracious curiosity and appetite for learning sustaining him throughout his long life. After years as a surveyor and builder, in 1848 he left Britain to become a professional natural history collector in the Amazon, where he spent four years. Then, in 1854, he departed for the Malay Archipelago. It was on this voyage that he constructed a theory of natural selection similar to the one Charles Darwin was developing, and the two copublished papers on the subject in 1858, some sixteen months before the release of Darwin’s On the Origin of Species. But as the contributors to the Companion show, this much-discussed parallel evolution in thought was only one epoch in an extraordinary intellectual life. When Wallace returned to Britain in 1862, he commenced a career of writing on a huge range of subjects extending from evolutionary studies and biogeography to spiritualism and socialism. An Alfred Russel Wallace Companion provides something of a necessary reexamination of the full breadth of Wallace’s thought—an attempt to describe not only the history and present state of our understanding of his work, but also its implications for the future.
Alfred Wegener: Science, Exploration, and the Theory of Continental Drift
by Mott T. GreeneA masterful biography of Alfred Wegener (1880–1930), the German scientist who discovered continental drift.Winner of the CHOICE Outstanding Academic Title of the Choice ACRLAlfred Wegener aimed to create a revolution in science which would rank with those of Nicolaus Copernicus and Charles Darwin. After completing his doctoral studies in astronomy at the University of Berlin, Wegener found himself drawn not to observatory science but to rugged fieldwork, which allowed him to cross into a variety of disciplines. The author of the theory of continental drift—the direct ancestor of the modern theory of plate tectonics and one of the key scientific concepts of the past century—Wegener also made major contributions to geology, geophysics, astronomy, geodesy, atmospheric physics, meteorology, and glaciology. Remarkably, he completed this pathbreaking work while grappling variously with financial difficulty, war, economic depression, scientific isolation, illness, and injury. He ultimately died of overexertion on a journey to probe the Greenland icecap and calculate its rate of drift. This landmark biography—the only complete account of the scientist’s fascinating life and work—is the culmination of more than twenty years of intensive research. In Alfred Wegener, Mott T. Greene places Wegener’s upbringing and theoretical advances in earth science in the context of his brilliantly eclectic career, bringing Wegener to life by analyzing his published scientific work, delving into all of his surviving letters and journals, and tracing both his passionate commitment to science and his thrilling experiences as a polar explorer, a military officer during World War I, and a world-record–setting balloonist. In the course of writing this book, Greene traveled to every place that Alfred Wegener lived and worked—to Berlin, rural Brandenburg, Marburg, Hamburg, and Heidelberg in Germany; to Innsbruck and Graz in Austria; and onto the Greenland icecap. He also pored over archives in Copenhagen, Munich, Marburg, Graz, and Bremerhaven, where the majority of Wegener’s surviving papers are found. Written with great immediacy and descriptive power, Alfred Wegener is a powerful portrait of the scientist who pioneered the modern concept of unified Earth science. The book should be of interest not only to earth scientists, students of polar travel and exploration, and historians but to all readers who are fascinated by the great minds of science.

Algae and Environmental Sustainability (Developments in Applied Phycology #7)
by Faizal Bux Bhaskar Singh Kuldeep BauddhThis book presents the dynamic role of algae in a sustainable environment. Two major aspects, namely bioenergy and bioremediation, have been elaborated in various chapter contributed by scientists and teachers from different geographical areas throughout the world. Algal biofuels is an emerging area of equal interest to researchers, industries, and policy makers working or focusing on alternative (i. e. renewable) fuels. Algae have been an area of interest due to their wide range of applications. Over the last 5 decades, eukaryotic algae have been used in the aquaculture industry as feed for invertebrates, providing a rich source of antioxidants, dietary fiber, minerals and protein. More recently, there has been a focus on the use of algal biomass in the development of alternative fuels. The extraction of oil from algae has been widely explored as a much more viable feedstock than plant-based oils in large-scale fuel production. using algae as feedstock has the advantages that it doesn't require arable land and that wastewater can be used as a source of nutrients in their culture. The multifunctional approach of algae includes pollution remediation, carbon sequestration, biofuels production, and delivery of value-added products. However, there are still some obstacles that need to be overcome to make their use as potential feedstock for biofuels techno-economically feasible. In order to maintain the sustainability aspect of algal biofuels, various aspects have to be studied and critically analyzed to assess the long-term sustainability of algal derived biofuels. This book discusses the role of algae as a promising future feedstock for biofuels. They are known to sequester carbon in much larger amounts than plants and as such the book also describes their phycoremediation potential for conventional as well as emerging contaminants. It describes the role of anaerobic digestion in algal biorefineries; bioreactions and process parameters; biogas recovery and reuse. The role of algal biofilm based technology in wastewater treatment and transforming waste into bio-products is discussed, and remediation of sewage water through algae is assessed. The book also describes the production of biohydrogen, bio-oil, biodiesel; and the major bottlenecks in their usage. The emerging characterization techniques of these biofuels (bio-oil and biodiesel) are described, as are the decolorizing potential of algae and the genetic engineering techniques that could enhance the production of lipids in algae. Other aspects of the book include the role of remote sensing technology in the monitoring of algae and a life cycle assessment of algal biofuels.
Algae in Agrobiology: Realities and Perspectives
by Joel FleurenceAlgae, macroalgae and microalgae can be valuable biological resources in a new, more environmentally friendly form of agriculture known as agrobiology. Indeed, the biological properties associated with algae are frequently relevant for agricultural and zootechnical purposes. It is this aspect that is behind the current popularity of algae in the development of new agricultural practices that are related to plant and animal production, which are referred to as agrobiology. Algae in Agrobiology offers a current and forward-looking account of algae use: in agriculture and in the sector of land and marine animal production, as algal extracts and molecules in the form of fertilizers or biostimulants for crops with agronomic interest, and as algal compounds in the area of plant and animal health. This book is based on advances in biochemical and agronomic research in order to explain the conventional practices associated with the use of algae in agriculture and livestock breeding. These advances make it possible to establish possible uses for marine algal resources in the agriculture of the future.

Algal Biorefinery: An Integrated Approach
by Debabrata DasThis book critically discusses different aspects of algal production systems and several of the drawbacks related to microalgal biomass production, namely, low biomass yield, and energy-consuming harvesting, dewatering, drying and extraction processes. These provide a background to the state-of-the-art technologies for algal cultivation, CO2 sequestration, and large-scale application of these systems. In order to tap the commercial potential of algae, a biorefinery concept has been proposed that could help to extract maximum benefits from algal biomass. This refinery concept promotes the harvesting of multiple products from the feedstock so as to make the process economically attractive. For the last few decades, algal biomass has been explored for use in various products such as fuel, agricultural crops, pigments and pharmaceuticals, as well as in bioremediation. To meet the huge demand, there has been a focus on large-scale production of algal biomass in closed or open photobioreactors. Different nutritional conditions for algal growth have been explored, such as photoautotrophic, heterotrophic, mixotrophic and oleaginous. This book is aimed at a wide audience, including undergraduates, postgraduates, academics, energy researchers, scientists in industry, energy specialists, policy makers and others who wish to understand algal biorefineries and also keep abreast of the latest developments.

Algebraic Structure of String Field Theory (Lecture Notes in Physics #973)
by Martin Doubek Branislav Jurčo Martin Markl Ivo SachsThis book gives a modern presentation of modular operands and their role in string field theory. The authors aim to outline the arguments from the perspective of homotopy algebras and their operadic origin. Part I reviews string field theory from the point of view of homotopy algebras, including A-infinity algebras, loop homotopy (quantum L-infinity) and IBL-infinity algebras governing its structure. Within this framework, the covariant construction of a string field theory naturally emerges as composition of two morphisms of particular odd modular operads. This part is intended primarily for researchers and graduate students who are interested in applications of higher algebraic structures to strings and quantum field theory. Part II contains a comprehensive treatment of the mathematical background on operads and homotopy algebras in a broader context, which should appeal also to mathematicians who are not familiar with string theory.

Algorithms and the Assault on Critical Thought: Digitalized Dilemmas of Automated Governance and Communitarian Practice (Routledge Series on Digital Spaces)
by Nancy EttlingerThis book examines the digitalization of longstanding problems of technological advance that produce inequalities and automated governance, which relieves subjects of agency and critical thought, and prompts a need to weaponize thoughtfulness against technocratic designs. The book situates digital-era problems relative to those of previous sociotechnical milieux and argues that technical advance perennially embeds corrosive effects on social relations and relations of production, recognizing variation across contexts and relative to entrenched societal hierarchies of race and other axes of difference and their intersections. Societal tolerance, despite abundant evidence for harmful effects of digital technologies, requires attention. The book explains blindness to social injustice by technocratic thinking delivered through education as well as truths embraced in the data sciences coupled with governance in universities and the private sector that protect these truths from critique. Institutional inertia suggests benefits of communitarianism, which strives for change emanating from civil society. Scaling postcapitalist communitarian values through communitybased peer production presents opportunities. However, enduring problems require critical reflection, continual revision of strategies, and active participation among diverse community citizens. This book is written with critical geographic sensibilities for an interdisciplinary audience of scholars and graduate and undergraduate students in the social sciences, humanities, and data sciences.

Alien Gene Transfer in Crop Plants, Volume 1: Innovations, Methods and Risk Assessment
by Aditya Pratap Jitendra KumarGenetic engineering and biotechnology along with conventional breeding have played an important role in developing superior cultivars by transferring economically important traits from distant, wild and even unrelated species to the cultivated varieties which otherwise could not have been possible with conventional breeding. There is a vast amount of literature pertaining to the genetic improvement of crops over last few decades. However, the wonderful results achieved by crop scientists in food legumes’ research and development over the years are scattered in different journals of the World. <P><P> The two volumes in the series ‘Alien Gene Transfer in Crop Plants’ address this issue and offer a comprehensive reference on the developments made in major food crops of the world. These volumes aim at bringing the contributions from globally renowned scientists at one platform in a reader-friendly manner.<P><P> The 1st volume entitled, ‘Alien Gene Transfer in Crop Plants: Innovations, Methods and Risk Assessment” will deal exclusively with the process and methodology. The contents of this volume have been designed to appraise the readers with all the theoretical and practical aspects of wide hybridization and gene transfer like processes and methods of gene transfer, role of biotechnology with special reference to embryo rescue, genetic transformation, protoplast fusion and molecular marker technology, problems such as cross incompatibility and barriers to distant hybridization and solutions to overcome them. Since wild and weedy relatives of crop plants may have negative traits associated with them, there are always possibilities of linkage drag while transferring alien alleles. Therefore, problems and limitations of alien gene transfer from these species will also be discussed in this series. Further, the associated risks with this and assessment of risks will also be given due weightage.
