Book excerpt: "Native Pacific Islander writer Craig Santos Perez has crafted a timely collection of eco-poetry comprised of free verse, prose, haiku, sonnets, satire, and a form he calls "recycling." Habitat Threshold begins with the birth and growth of the author's daughter and captures her childlike awe at the wondrous planet. As the book progresses, however, Perez confronts the impacts of environmental injustice, global capitalism, toxic waste, animal extinctions, water struggles, human violence, mass migration, and climate change. Throughout, Perez mourns lost habitats and species and faces his fears about the world his daughter will inherit. Yet this work does not end at the threshold of elegy; instead, the poet envisions a sustainable future in which our ethics are shaped by the indigenous belief that the earth is sacred and all beings are interconnected--a future in which we cultivate love and "carry each other towards the horizon of care.""--

Download or read book Effective Ecological Monitoring written by Gene Likens and published by CSIRO PUBLISHING. This book was released on 2018-05-01 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: Long-term monitoring programs are fundamental to understanding the natural environment and managing major environmental problems. Yet they are often done very poorly and ineffectively. This second edition of the highly acclaimed Effective Ecological Monitoring describes what makes monitoring programs successful and how to ensure that long-term monitoring studies persist. The book has been fully revised and updated but remains concise, illustrating key aspects of effective monitoring with case studies and examples. It includes new sections comparing surveillance-based and question-based monitoring, analysing environmental observation networks, and provides examples of adaptive monitoring. Based on the authors’ 80 years of collective experience in running long-term research and monitoring programs, Effective Ecological Monitoring is a valuable resource for the natural resource management, ecological and environmental science and policy communities.

This book was released on 1995-10-13 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Endangered Species Act (ESA) is a far-reaching law that has sparked intense controversies over the use of public lands, the rights of property owners, and economic versus environmental benefits. In this volume a distinguished committee focuses on the science underlying the ESA and offers recommendations for making the act more effective. The committee provides an overview of what scientists know about extinctionâ€"and what this understanding means to implementation of the ESA. Habitatâ€"its destruction, conservation, and fundamental importance to the ESAâ€"is explored in detail. The book analyzes: Concepts of speciesâ€"how the term "species" arose and how it has been interpreted for purposes of the ESA. Conflicts between species when individual species are identified for protection, including several case studies. Assessment of extinction risk and decisions under the ESAâ€"how these decisions can be made more effectively. The book concludes with a look beyond the Endangered Species Act and suggests additional means of biological conservation and ways to reduce conflicts. It will be useful to policymakers, regulators, scientists, natural-resource managers, industry and environmental organizations, and those interested in biological conservation.

This book was released on 2020-10-08 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the advent of global warming and the nuclear arms race, humans are rapidly approaching a moment of truth. Technologically supreme, they manifest their dreams and nightmares in the real world through science, art, adventures and brutal wars, a paradox symbolized by a candle lighting the dark yet burning away to extinction, as discussed in this book. As these lines are being written, fires are burning on several continents, the Earth’s ice sheets are melting and the oceans are rising, threatening to flood the planet’s coastal zones and river valleys, where civilization arose and humans live and grow food. With the exception of birds like hawks, black kites and fire raptors, humans are the only life form utilizing fire, creating developments they can hardly control. For more than a million years, gathered around campfires during the long nights, mesmerized by the flickering life-like dance of the flames, prehistoric humans acquired imagination, a yearning for omnipotence, premonitions of death, cravings for immortality and conceiving the supernatural. Humans live in realms of perceptions, dreams, myths and legends, in denial of critical facts, waking up for a brief moment to witness a world that is as beautiful as it is cruel. Existentialist philosophy offers a way of coping with the unthinkable. Looking into the future produces fear, an instinctive response that can obsess the human mind and create a conflict between the intuitive reptilian brain and the growing neocortex, with dire consequences. As contrasted with Stapledon’s Last and first Man, where an advanced human species mourns the fate of the Earth, Homo sapiens continues to transfer every extractable molecule of carbon from the Earth to the atmosphere, the lungs of the biosphere, ensuring the demise of the planetary life support system.”

This book was released on 2011-07-06 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume presents explicit approximations of the quasi-stationary distribution and of the expected time to extinction from the state one and from quasi-stationarity for the stochastic logistic SIS model. The approximations are derived separately in three different parameter regions, and then combined into a uniform approximation across all three regions. Subsequently, the results are used to derive thresholds as functions of the population size N.

This book was released on 2013-03-14 with total page 213 pages. Available in PDF, EPUB and Kindle. Book excerpt: Optical communications networks are an essential part of the world wide te- communication infrastructure . The number of users of present and future telecommunication services like Internet, web browsing and tele-education is expected to increase dramatically . As a consequence there is an imminent - mand for high broadband and high capacity communication systems. A prom- ing solution is found in the concept of all-optical networks . These networks exploit the vast capacity of the optical fiber by using multiplexing techniques that allow for an overall capacity of terabits per second. Channels are routed and switched in the optical domain . In this manner data channels are carried from the receiver side to its destination making use of optical transmission techniques . Wavelength division multiplexing (WDM) is a transmission technique that has dramatically increased the capacity of optical transmission systems. WDM allows for transmission of several channels over a single optical fiber by - ing different wavelength as the channel carrier . Optical switching and routing techniques are also being developed to cope with the high data speeds and n- ber of channel carried in the optical fibers. These functionalities are provided by optical crossconnects. The use of transmission techniques such as WDM in combination with optical crossconnects is enabling optical networking at high bit-rates reaching terabits per second . These techniques also offer ways to improve the network flexibility and configurability .

Available in PDF, EPUB and Kindle. Book excerpt: Alien species (weeds and pest animals) are acknowledged as the second greatest cause of biodiversity decline, after habitat loss. Despite this, there is a lack of information on the biodiversity at risk from alien species. This lack has hampered effective management of invasive species at all levels from government policy to on-ground control. Given that the number of new introductions of alien species has increased dramatically over the past century, it is imperative that proper information on their impacts be compiled and disseminated.

Download or read book Human-Environment Interactions written by Mark R. Welford and published by Springer Nature. This book was released on 2020-10-06 with total page 251 pages. Available in PDF, EPUB and Kindle. Book excerpt: This textbook explores the growing area of human-environment interaction. We live in the Anthropocene, an era dominated by humans, but also by the positive yet destructive environmental feedbacks that are poised to completely reset the relationships between nature and society. Modern and historic political, social, and cultural processes and physical landscape responses determine the intensity of these impacts. Yet different cultural groups, political and economic entities view, react to, and impact these human-environmental processes in spatially distinct and divergent ways. Providing an accessible, up-to-date, approach to human-environment interactions with balanced coverage of both social and natural science approaches to core environmental issues, this textbook is an integrative, multi-disciplinary offering that discusses environmental issues and processes within the context of human societies. The book begins by addressing the three most pressing issues of our time: climate change, threshold exceedance, and the 6th mass extinction. From there the authors identify within chapters on resources, population, agriculture and urbanization what precipitated and continues to sustain these three issues. They end with a chapter outlining some practical solutions to our human-environment crises. The book will be a valuable resource for interdisciplinary environment related courses bridging the gap between the social and natural sciences, human geographies and physical geographies.
