Satellites in the High Country - Searching for the Wild in the Age of Man (Hardcover): Jason Mark Satellites in the High Country - Searching for the Wild in the Age of Man (Hardcover)
Jason Mark

In New Mexico's Gila Wilderness, 83 Mexican gray wolves may be some of the most monitored wildlife on the planet. Collared, microchipped, and transported by helicopter, the wolves are protected and confined in an attempt to appease ranchers and conservationists alike. Once a symbol of the wild, these wolves have come to illustrate the demise of wilderness in this Human Age, where man's efforts shape life in even the most remote corners of the earth. And yet, the howl of an unregistered wolf, half of a rogue pair, splits the night. If you know where to look, you'll find that much remains untamed, and even today, wildness can remain a touchstone for our relationship with the rest of nature. In Satellites in the High Country, journalist and adventurer Jason Mark travels beyond the bright lights and certainties of our cities to seek wildness wherever it survives. In California's Point Reyes National Seashore, a battle over oyster farming and designated wilderness pits former allies against one another, as locals wonder whether wilderness should be untouched, farmed, or something in between. In Washington's Cascade Mountains, a modern-day wild woman and her students learn to tan hides and start fires without matches, attempting to connect with a primal past out of reach for the rest of society. And in Colorado's High Country, dark skies and clear air reveal a breathtaking expanse of stars, flawed only by the arc of a satellite passing - beauty interrupted by the traffic of a million conversations. These expeditions to the edges of civilization's grid show us that, although our notions of pristine nature may be shattering, the mystery of the wild still exists, and in fact, it is more crucial than ever. But wildness is wily as a coyote: you have to be willing to track it to understand the least thing about it. Satellites in the High Country is an epic journey on the trail of the wild, a poetic and incisive exploration of its meaning and enduring power in our Human Age.

This book explores how we can solve the urgent problem of optimizing the use of variable, uncertain but finite fisheries resources while maintaining sustainability from a marine-ecosystem conservation perspective. It offers readers a broad understanding of the current methods and theory for sustainable exploitation of fisheries resources, and introduces recent findings and technological developments. The book is divided into three parts: Part I discusses fish stock dynamics, and illustrates how ecological processes affecting life cycles and biological interactions in marine environments lead to fish stock variability in space and time in major fish groups; small pelagic fish, demersal fish and large predatory fish. These insights shed light on the mechanisms underlying the variability in fish stocks and form the essential biological basis for fisheries management. Part II addresses the technologies and systems that monitor changes in fisheries resources and marine ecosystems using two approaches: fishery-dependent and fishery-independent data. It also describes acoustic surveys and biological sampling, as well as stock assessment methods. Part III examines management models for effectively assessing the natural variability in fisheries resources. The authors explore ways of determining the allowable catch in response to changes in stock abundance and how to incorporate ecological processes and monitoring procedures into management models. This book offers readers a broad understanding of sustainable exploitation as well as insights into fisheries management for the next generation.

"Conservation of Tropical Birds" has been written by four conservation biologists whose expertise spans all the tropical regions of the world. It is the first book to cover all the major issues in tropical bird conservation. Current problems faced by tropical bird conservationists are summarised and potential solutions outlined based on the results of case studies.

Birds are key indicators of ecosystem health, and such a well-studied group of organisms, that they provide an excellent lens through which to examine global conservation problems caused by phenomena such as climate change, declines in ecosystem services, habitat loss, fires, overexploitation, and invasive species. Therefore, the book also provides an engaging synopsis of the general issues in conservation and the problems faced by other wildlife.

This book serves as an important resource and companion to all people interested in observing and conserving birds in the tropics and elsewhere.

From flat-topped acacia trees to great migrations of wildebeest across an edgeless expanse of grass, the Serengeti is one of the world's most renowned ecosystems. And at the apex of this incredible landscape prowls its seemingly indomitable ruler: the Serengeti lion. These majestic mammals are skillful hunters, iconic, and integral to Serengeti health. But they also commit infanticide, eat local people and destroy local livelihoods, are a source of profit for those who make money shooting or conserving them (and sometimes both), and are in constant danger from the encroachments of another species: humans. With Lions in the Balance, celebrated lion researcher and conservationist Craig Packer takes us back into the complex, tooth-and-claw worlds of lion conservation and behavior. A sequel to Packer's Into Africa-which gave many readers their first experience of field work in Africa, of Tanzanian roads, of long hours spent identifying lions by their ear marks and scars, and of the joys of bootlegged Grateful Dead tapes beneath savannah moons-this diary-based chronicle of adventure, real-life danger, and corruption will both alarm and entertain. Packer's story offers a look into the future of the lion, one in which the politics of conservation will require survival strategies far more creative and powerful than any now possessed by the citizens of the savannah-humans included. Packer is sure to infuriate poachers, politicians, and conservationists alike as he minces no words about the problems he sees. But with a narrative stretching from Arusha to Washington, DC, and marked by Packer's signature humor and incredible candor, Lions in the Balance is a tale of courage against impossible odds, a masterly blend of science and storytelling, and an urgent call to action that will captivate a pride of readers.

R653 Discovery Miles 6 530 Shipped within 7 - 11 working days

Native only to the California Channel Islands, the island fox is the smallest canid in North America. Populations on four of the islands were threatened to extinction in the 1990s due to human-mediated predation and disease. This is the first account of the natural history and ecology of the island fox, illustrating both the vulnerability of island ecosystems and the efficacy of cooperative conservation measures. It explains in detail the intense conservation actions required to recover fox populations, such as captive breeding and reintroduction, and large-scale ecosystem manipulation. These actions were successful due in large part to extraordinary collaboration among the scientists, managers and public advocates involved in the recovery effort. The book also examines the role of some aspects of island fox biology, characteristic of the 'island syndrome', in facilitating their recovery, including high productivity and an apparent adaptation to periodic genetic bottlenecks.

Arthropods are invertebrates that constitute over 90% of the animal kingdom, and their bio-ecology is closely linked with global functioning and survival. Arthropods play an important role in maintaining the health of ecosystems, provide livelihoods and nutrition to human communities, and are important indicators of environmental change. Yet the population trends of several arthropods species show them to be in decline. Arthropods constitute a dominant group with 1.2 million species influencing earth's biodiversity. Among arthropods, insects are predominant, with ca. 1 million species and having evolved some 350 million years ago. Arthropods are closely associated with living and non-living entities alike, making the ecosystem services they provide crucially important. In order to be effective, plans for the conservation of arthropods and ecosystems should include a mixture of strategies like protecting key habitats and genomic studies to formulate relevant policies for in situ and ex situ conservation. This two-volume book focuses on capturing the essentials of arthropod inventories, biology, and conservation.Further, it seeks to identify the mechanisms by which arthropod populations can be sustained in terrestrial and aquatic ecosystems, and by means of which certain problematic species be managed without producing harmful environmental side-effects. This edited compilation includes chapters contributed by over 80 biologists on a wide range of topics embracing the diversity, distribution, utility and conservation of arthropods and select groups of insect taxa. More importantly, it describes in detail the mechanisms of sustaining arthropod ecosystems, services and populations. It addresses the contribution of modern biological tools such as molecular and genetic techniques regulating gene expression, as well as conventional, indigenous practices in arthropod conservation. The contributors reiterate the importance of documenting and understanding the biology of arthropods from a holistic perspective before addressing conservation issues at large. This book offers a valuable resource for all zoologists, entomologists, ecologists, conservation biologists, policy makers, teachers and students interested in the conservation of biological resources.

Post-war Afghanistan is fragile, volatile, and perilous. It is also a place of extraordinary beauty. Evolutionary biologist Alex Deghan came to Afghanistan and created a startup, Conservation X Labs, to save Afghanistan's unique and extraordinary wildlife and natural landscape after decades of war. His workplace was so remote that roads themselves would disappear, and travel was by foot, yak, or mule, following ancient pathways for weeks into the mountain kingdoms and desolate landscapes. Conservation, it turned out, provided a common bond between Alex's team and the people of Afghanistan, where his international team worked unarmed in some of the most dangerous places in the country. They successfully built the country's first national park, completed the first wildlife survey in thirty years, and worked to stop the poaching of the country's iconic endangered animals, including the elusive snow leopard. In doing so, they restored a part of Afghan identity that is ineffably tied to the land itself. For a people who had spent decades as refugees or subject to the horrors and desolation of war, the quest to restore Afghanistan's wildlife became the restoration of Afghanistan's very culture and deep history.

Amphibian species around the world are unusually vulnerable to a variety of threats, by no means all of which are properly understood. Volume 11 in this major series is published in parts devoted to the causes of amphibian decline and to conservation measures in regions of the world. This volume, Part 4 in the series, is concerned with Southern Europe (Italy, Malta, Croatia, Slovenia, Serbia, Montenegro, Bosnia and Herzegovina, Macedonia, Albania, Greece, Romania, Hungary, Bulgaria, Turkey, and Cyprus). Each chapter has been written by experts from each country, describing the ecological background and the conservation status of affected species, with an emphasis on native species. As well as infectious diseases and parasites, threats take the form of introduced and invasive species, pollution, destruction and alteration of habitat, and climatic change. These are discussed as they affect each species. All these countries have monitoring schemes and conservation programs, whose origins and activities are described. Recommendations for action are also made. Edited by leading scholars in the field, Volume 11, when complete, will provide a definitive survey of the amphibian predicament and a stimulus to further research with the objective of arresting the global decline of an entire class of animal.

This book compiles the latest findings in the field of marine and brackishwater aquaculture. It covers significant topics such as techniques of culture of live feeds (microalgae, rotifer, Artemia, marine copepod & polychaetes), while also highlighting vital themes like the culture and applications of free and marine sponge associated microbial probiotics, controlled breeding, seed production and culture of commercially important fin and shell fishes. Moreover, the book focuses on the breeding and culture of marine ornamental fishes, sea cucumber and sea urchin and discusses seaweeds culture, aqua feed formulation and nutrition, water quality management in hatchery and grow-out culture systems, fish disease diagnosis and health management and cryopreservation of fish gametes for sustainable aquaculture practices, all from a multidimensional perspective. The global fish production was 154 million tonnes in 2011 which more or less consisted of capture and culture fisheries (FAO, 2012). Roughly 80% of this is from inland-freshwater aquaculture and the remainder from capture fisheries in the marine and brackishwater sector. However, marine and brackishwater catches have recently begun to diminish due to overexploitation, climate change and pollution. The UNEP report affirmed that if the world remains on its current course of overfishing, by 2050, the ocean fish stock could become extinct or no longer commercially viable to exploit. In these circumstances, aquaculture is considered to be a promising sector to fulfill our future protein requirement. However, brackishwater and marine fish production now face serious challenges due to e.g. lack of quality fish seeds, feeds, poor water quality management and diseases. Fisheries and aquaculture sectors play a vital role as potential sources of nutritional security and food safety around the globe. Fish food is rich in protein, vitamins, phosphorous, calcium, zinc, selenium etc. In addition, fish contains omega-3 fatty acids, which help to prevent cardiovascular diseases. Fish food can also provide several health benefits to consumers. The omega 3 fatty acids found in fish can reduce the levels of LDL cholesterol (the "bad" cholesterol) and increase the HDL levels (the "good" cholesterol). Research conducted in Australia has proved that fish consumption can be used to cure hypertension and obesity. It is also reported that people who ate more fish were less prone to asthma and were able to breathe more easily. Omega 3 fish oil or fish consumption can help to prevent three of the most common forms of cancer: breast cancer, colon and prostate cancer. The omega 3 fatty acids present in fish or fish oil induce faster hair growth and prevent hair loss. Since most varieties of fish are rich in protein, eating fish helps to keep hair healthy. Furthermore, fish or fish oil helps in improving the condition of dry skin, giving it a healthy glow. It is useful in treating various skin problems such as eczema, psoriasis, itching, redness of skin, skin lesions and rashes. It is well known that eating fish improves vision and prevents Alzheimer's and type-2 diabetes, and can combat arthritis. Further, fish oil or fish is good for pregnant women, as the DHA present in it helps in the development of the baby's eyes and brain. It helps to avoid premature births, low birth weights and miscarriages. In addition, it is widely known that fish can be a good substitute for pulses in cereal-based diets for the poor. The global fish production was roughly 154 million tonnes in 2011 (FAO, 2012). It is estimated that by 2020 global fish requirements will be over 200 million tonnes; as such, innovative technological improvements are called for in order to improve the production and productivity in fisheries. In this context, this book provides valuable information for academics, scientists, researchers, government officials and farmers on innovative technological advances for sustainable fish production using aquaculture methods. The book identifies the main issues and trends in marine and brackishwater aquaculture from a global perspective in general and in the Indian context in particular. It includes 23 chapters written by prominent researchers from various institutes and universities across India, who address the latest aquaculture technologies with distinctive approaches to support academics, researchers and graduates in the fields of Fisheries, Aquaculture, Marine Science, Marine Biology, Marine Biotechnology, Zoology and Agricultural Sciences. Our thanks go to our contributors; we are confident that all readers will immensely benefit from their valued expertise in the field of marine and brackishwater aquaculture.

Adaptive management is an approach to managing social-ecological systems that fosters learning about the systems being managed and remains at the forefront of environmental management nearly 40 years after its original conception. Adaptive management persists because it allows action despite uncertainty, and uncertainty is reduced when learning occurs during the management process. Often termed "learning by doing", the allure of this management approach has entrenched the concept widely in agency direction and statutory mandates across the globe. This exceptional volume is a collection of essays on the past, present and future of adaptive management written by prominent authors with long experience in developing, implementing, and assessing adaptive management. Moving forward, the book provides policymakers, managers and scientists a powerful tool for managing for resilience in the face of uncertainty.

Cynthia Moss has studied the elephants in Kenya's Amboseli National Park for over twenty-seven years. Her long-term research has revealed much of what we now know about these complex and intelligent animals. Here she chronicles the lives of the members of the T families led by matriarchs Teresia, Slit Ear, Torn Ear, Tania, and Tuskless. With a new afterword catching up on the families and covering current conservation issues, Moss's story will continue to fascinate animal lovers.
"One is soon swept away by this 'Babar' for adults. By the end, one even begins to feel an aversion for people. One wants to curse human civilization and cry out, 'Now God stand up for the elephants!'"--Christopher Lehmann-Haupt, "New York Times"
"Moss speaks to the general reader, with charm as well as scientific authority. . . . [An] elegantly written and ingeniously structured account." --Raymond Sokolov, "Wall Street Journal"
"Moss tells the story in a style so conversational . . . that I felt like a privileged visitor riding beside her in her rickety Land-Rover as she showed me around the park." --Sarah Blaffer Hrdy, "New York Times Book Review"

Does extinction have to be forever? As the global extinction crisis accelerates, conservationists and policy-makers increasingly use advanced biotechnologies such as reproductive cloning, polymerase chain reaction (PCR) and bioinformatics in the urgent effort to save species. Mendel's Ark considers the ethical, cultural and social implications of using these tools for wildlife conservation. Drawing upon sources ranging from science to science fiction, it focuses on the stories we tell about extinction and the meanings we ascribe to nature and technology. The use of biotechnology in conservation is redrawing the boundaries between animals and machines, nature and artifacts, and life and death. The new rhetoric and practice of de-extinction will thus have significant repercussions for wilderness and for society. The degree to which we engage collectively with both the prosaic and the fantastic aspects of biotechnological conservation will shape the boundaries and ethics of our desire to restore lost worlds.
