This book will provide the state-of-the-art on most of the topics involved in the ecology and conservation of birds of prey. With chapters authored by the most recognized and prestigious researchers on each of the fields, this book will become an authorized reference volume for raptor biologists and researchers around the world.
This book is a unique collection of evolutionary and ecological perspectives in the study of biodiversity by some of the leading researchers in the field. The seventeen chapters are divided into three sections, each section beginning with an overview of its contents. The book traces past landmarks, current questions, and future trends in biodiversity reseach ranging from the evaluation of the fossil record and molecular phylogenies in untangling the genesis of diversity; to population, community, and ecosystem-level approaches in understanding patterns of species persistence; and finally to large-scale diversity patterns and species conservation. Subject reviews, case-studies, and discussions of techniques are combined to produce a state-of-the-art book.
'When a man plants a tree, he plants himself. Every root is an anchor, over which he rests with grateful interest, and becomes sufficiently calm to feel the joy of living.' Steep Trails encompasses a delightful mix of John Muir's essays and adventure narratives, spanning a period of twenty-nine years. The selections included in this book are varied: ranging from geological studies to stories of the people and towns he encounters throughout his exploits. As Muir expert Terry Gifford observes in the foreword, 'Most of Steep Trails' chapters are dispatches from Muir as travelling correspondent with a mixture of insights into local cultures, criticism of pollution and enthusiasm for everything wild.' Muir's refreshing philosophy of being 'at one' with nature shines through every account he details, as does his agenda for environmental activism - to treat wildness lovingly, rather than selfishly for material greed. Covering mostly the western regions of the states, California, Washington, Nevada, The Grand Canyon, Oregon and Utah; Steep Trails showcases Muir's passion continuously as he climbs mountains, bathes in lakes, and sketches his findings. Muir's classic extended metaphors and knowledgeable tone are present throughout, making for both an enjoyable and educational read. The enthusiasm contained within these pages is infectious, and as well as simply describing the beauty he sees, Muir will inspire you too, to 'go and see for yourselves' the rewards of studying the endless gift of nature: 'Surely faithful and loving skill can go no farther in putting the multitudinous decorated forms on paper. But the colours, the living, rejoicing colours, chanting morning and evening in chorus to heaven! Whose brush or pencil, however lovingly inspired, can give us these? And if paint is of no effect, what hope lies in pen-work? Only this: some may be incited by it to go and see for themselves.'
This book places lion conservation and the relationship between people and lions both in historical context and in the context of the contemporary politics of conservation in Africa. The killing of Cecil the Lion in July 2015 brought such issues to the public's attention. Were lions threatened in the wild and what was the best form of conservation? How best can lions be saved from extinction in the wild in Africa amid rural poverty, precarious livelihoods for local communities and an expanding human population? This book traces man's relationship with lions through history, from hominids, to the Romans, through colonial occupation and independence, to the present day. It concludes with an examination of the current crisis of conservation and the conflict between Western animal welfare concepts and sustainable development, thrown into sharp focus by the killing of Cecil the lion. Through this historical account, Keith Somerville provides a coherent, evidence-based assessment of current human-lion relations, providing context to the present situation. This book will be of interest to students and scholars of environmental and African history, wildlife conservation, environmental management and political ecology, as well as the general reader.
With a foreword by Sir David Attenborough, breathtakingly beautiful still photography, specially commissioned maps and graphics, and compelling text expanding on the remarkable TV stories and giving the reader a depth of information that is impossible on screen, this companion to the groundbreaking NETFLIX series presents a whole new view of the place we call home. Featuring some of the world's rarest creatures and previously unseen parts of the Earth—from deep oceans to remote forests to ice caps—Our Planet takes nature-lovers deep into the science of our natural world. Revealing the most amazing sights on Earth in unprecedented ways, alongside stories of the ways humans are affecting the world’s ecosystems—from the wildebeest migrations in Africa to the penguin colonies of Antarctica—this book captures in one concise narrative a fundamental message: What we do in the next twenty years will determine the future of not just the natural world but humanity itself. If we don't act now to protect and preserve our planet, the beauty we're lucky enough to witness on these pages will have disappeared...
A completely new look at plants - not only in food, drink and commerce, and how they have created civilisation, trade and empires, but also in love, in war, in crime, in horror and delight, in music, poetry and prose, and on the screen. Not just another gardening or plant book, this is a complete picture of how plants affect people, for better or worse, now, in the past and in the future with illuminating and startling facts about their ubiquitous presence in human affairs - through life, death, illness, happiness, murder, despair, desperation, love, hate, loss, and far more. From Presidents to pop stars, from scientists to slavers, royals to religious leaders, chefs to charlatans, pioneers to politicians, artists to actors, Plants & Us is a unique overview of plants, wild and cultivated, their vital importance and the threats they face. Above all, how they affect all our lives in stories that will often surprise the reader.
The aim of this book is to systematize and discuss population genetic studies of freshwater fish in a region that harbors the greatest diversity of species among all inland water ecosystems. This volume explores the genetic evaluation for a number of orders, families and species of Neotropical fishes, and provides an overview on genetic resources and diversity and their relationships with fish domestication, breeding, and food production.
If you could bring back just one animal from the past, what would you choose? It can be anyone or anything from history, from the King of the Dinosaurs, T. rex, to the King of Rock `n' Roll, Elvis Presley, and beyond. De-extinction - the ability to bring extinct species back to life - is fast becoming reality. Around the globe, scientists are trying to de-extinct all manner of animals, including the woolly mammoth, the passenger pigeon and a bizarre species of flatulent frog. But de-extinction is more than just bringing back the dead. It's a science that can be used to save species, shape evolution and sculpt the future of life on our planet. In Bring Back the King, scientist and comedy writer Helen Pilcher goes on a quest to identify the perfect de-extinction candidate. Along the way, she asks if Elvis could be recreated from the DNA inside a pickled wart, investigates whether it's possible to raise a pet dodo, and considers the odds of a 21st century Neanderthal turning heads on public transport. Pondering the practicalities and the point of de-extinction, Bring Back the King is a witty and wry exploration of what is bound to become one of the hottest topics in conservation - if not in science as a whole - in the years to come. READ THIS BOOK - the King commands it.
This book encompasses the body of available scientific information on the notothenioid fish Pleuragramma antarctica commonly known as Antarctic silverfish. This plankton-feeder of the intermediate trophic level is the most abundant fish in the coastal regions of high Antarctica, and plays a pivotal ecological role as the main prey of top predators like seals, penguins, whales and Antarctic toothfish. Broad circum-polar distribution, a key role in the Antarctic shelf pelagic ecosystem, and adaptations makes understanding the species' likely response to environmental change relevant to foresee the potential responses at the local ecosystem level. Additionally, a detailed understanding of the abundance and trophic interactions of such a dominant keystone species is a vital element of informing the development of marine spatial planning and marine protected areas in the Antarctic continental shelf region. Experts in the field provide here unique insights into the evolutionary adaptation, eco-physiology, trophic ecology, reproductive and population ecology of the Antarctic silverfish and provide new clues about its vulnerability in facing the challenges of the ongoing environmental changes.
This book explores how the state can foster collective action by fisher's communities in fisheries management. It presents a different perspective from Elinor Ostrom's classic work on the eight institutional conditions that foster collective action in natural resource management and instead emphasizes the role of the state in fisheries co-management, engaging a state-centric notion of 'meta-governance'. It argues that first, the state is required to foster collective action by fishers; and secondly, that the current fisheries co-management arrangements are state-centric. The study develops these arguments through the analysis of three case studies in Japan, Vietnam and Norway. The author also makes a theoretical contribution to governance literature by developing Ostrom's 'society-centric' framework in a way which makes it more amenable to the analysis of state capacity and government intervention in a comparative context. This book will appeal to students and scholars of global governance, fisheries management, co-management, and crisis management, as well as practitioners of fisheries management.
This book provides a snapshot of representative modeling analyses of coastal hypoxia and its effects. Hypoxia refers to conditions in the water column where dissolved oxygen falls below levels that can support most metazoan marine life (i.e., 2 mg O2 l-1). The number of hypoxic zones has been increasing at an exponential rate since the 1960s; there are currently more than 600 documented hypoxic zones in the estuarine and coastal waters worldwide. Hypoxia develops as a synergistic product of many physical and biological factors that affect the balance of dissolved oxygen in seawater, including temperature, solar radiation, wind, freshwater discharge, nutrient supply, and the production and decay of organic matter. A number of modeling approaches have been increasingly used in hypoxia research, along with the more traditional observational and experimental studies. Modeling is necessary because of rapidly changing coastal circulation and stratification patterns that affect hypoxia, the large spatial extent over which hypoxia develops, and limitations on our capabilities to directly measure hypoxia over large spatial and temporal scales. This book consists of 15 chapters that are broadly organized around three main topics: (1) Modeling of the physical controls on hypoxia, (2) Modeling of biogeochemical controls and feedbacks, and, (3) Modeling of the ecological effects of hypoxia. The final chapter is a synthesis chapter that draws generalities from the earlier chapters, highlights strengths and weaknesses of the current state-of-the-art modeling, and offers recommendations on future directions.
This book brings together leading conservation practitioners to reflect on their response to the current global biodiversity crisis, through the lens of island species recovery and management. Initial chapters cover the biological understanding of small population biology and the growing threat of invasive species, while subsequent chapters discuss the management of these threats and the complexity of leading projects within a dynamic and still relatively unknown system. Multiple case studies from islands worldwide illustrate key points, allowing readers to draw on the first-hand practical experience of experienced professionals. This resource will be invaluable to both current and future conservation professionals, helping them to go beyond disciplinary 'comfort zones' and develop, manage and lead projects over extensive timeframes in a way that brings others with them on the journey.
This book documents and examines the state of health of coral reefs in the eastern tropical Pacific region. It touches on the occurrence of coral reefs in the waters of surrounding countries, and it explores their biogeography, biodiversity and condition relative to the El Nino southern oscillation and human impacts. Additionally contained within is a field that presents information on many of the species presented in the preceding chapters.
Many endangered species of wild animals are managed in captivity through studbooks. In this book these data-rich resources are mined in innovative, integrated and statistically tested ways to maximise information gain for conservation practice - whether for captive or released/reintroduced or managed wild populations. This book is thus an important tool for all species managers, and for students and researchers in small population biology and wildlife conservation. The book's studbook analyses are grouped in three interrelated sections: natural history, demography and genetics. Statistical tests to determine the significance of results or to compare results between subgroups are undertaken throughout. Real studbooks of a variety of species, e.g. cranes, wolverines, blesbok, illustrate the practical applications and interpretations of the analyses and statistics. The "natural history" section presents analyses to determine baseline species information such as litter size, inter-birth interval, longevity and seasonality. "Demography" covers census(-style) analyses, age-class based life tables, comparative survival analyses and population projections. Solutions for dealing with small sample sizes are included.Inbreeding depression and unconscious selection form the main focus of the "genetics" section. Survival and life table analyses are used to assess inbreeding effects. Quantitative genetics methods are applied to natural history traits as a tool to monitor genetic variation. A fourth section on "conservation" shows how data from captive populations can be used where natural history data from wild populations are missing. A real example uses studbook data to inform Population Viability Analysis. The final section deals with issues related to incomplete and missing data and statistical topics. The purpose-written open-source software programs "Population Management Library (PML)" and "studbookR" used for analyses in the book, are available at www.princee.com.
This Brief discusses potential alternative sources for feeds in aquaculture fish diet, and explains that the future of aquaculture's development is dependent on the costs of fishmeal and fish oil. Considering that the increasing costs of traditional feeds constrain this development, research is looking into alternatives, which can ensure adequate nutrition for animals' growth. This work reviews the use of alternative plant, microbial and insect protein sources, evaluating in particular their impact on growth, nutrient digestibility, fillet quality traits and sensorial perception in the most important farmed marine and freshwater fish species. The Brief specifically summarizes the pros and cons of plant oils from oilseeds, which can on the one hand be a sustainable substitute for fish oil, but which are on the other hand less rich in omega-3 long-chain polyunsaturated fatty acids. The feeding might therefore result in an undesired reduced nutritional value of the flesh of farmed fish. The authors also explore the possible use of fishery discards as potential aquaculture feed source. Since the landing of by-catch will with the new Common Fisheries Policy (CFP) become obligatory (instead of simply returning it to the sea, often dead), suitable uses of what must not be used for human consumption can be investigated. The authors give an outlook whether this might become a sensible alternative to improve the management of discards and create more sustainable fisheries. The Brief also addresses the issues of additives to aquafeeds, such as vitamins, minerals, and antioxidants, but also immunostimulants and enzymes. The authors discuss which effects these additives may have on fish growth, welfare, reproduction and health status in aquacultures.
In Decolonizing Extinction Juno Salazar Parrenas ethnographically traces the ways in which colonialism, decolonization, and indigeneity shape relations that form more-than-human worlds at orangutan rehabilitation centers on Borneo. Parrenas tells the interweaving stories of wildlife workers and the centers' endangered animals while demonstrating the inseparability of risk and futurity from orangutan care. Drawing on anthropology, primatology, Southeast Asian history, gender studies, queer theory, and science and technology studies, Parrenas suggests that examining workers' care for these semi-wild apes can serve as a basis for cultivating mutual but unequal vulnerability in an era of annihilation. Only by considering rehabilitation from perspectives thus far ignored, Parrenas contends, could conservation biology turn away from ultimately violent investments in population growth and embrace a feminist sense of welfare, even if it means experiencing loss and pain.
In 2006, vaquita, a diminutive porpoise making its home in the Upper Gulf of California, inherited the dubious title of world’s most endangered marine mammal. Nicknamed “panda of the sea” for its small size and beguiling facial markings, vaquita have been in decline for decades, dying by the hundreds in gillnets intended for the commercially valuable fish, totoaba. When international crime cartels discovered a lucrative trade in the swim bladders of totoaba, illegal gillnetting went rampant, and now the lives of the few remaining vaquita hang in the balance. Author Brooke Bessesen takes us on a journey to Mexico’s Upper Gulf region to uncover the story. She interviewed townspeople, fishermen, politicians, scientists, and activists, teasing apart a complex story filled with villains and heroes, a story whose outcome is unclear. When diplomatic and political efforts to save the little porpoise failed, Bessesen traveled with a team of veterinary experts in a binational effort to capture the remaining ten vaquita and breed them in captivity—the only hope for their survival. In this fast-paced, soul-searing tale, she learned that there are no easy answers when extinction is profitable. Whether the rescue attempt succeeds or fails, the world must ask itself hard questions. When vaquita and the totoaba are gone, the black market will turn to the next vulnerable species. What will we do then?

Loss of biodiversity is among the greatest problems facing the world today. "Conservation and the Genetics of Populations" gives a comprehensive overview of the essential background, concepts, and tools needed to understand how genetic information can be used to conserve species threatened with extinction, and to manage species of ecological or commercial importance. New molecular techniques, statistical methods, and computer programs, genetic principles, and methods are becoming increasingly useful in the conservation of biological diversity. Using a balance of data and theory, coupled with basic and applied research examples, this book examines genetic and phenotypic variation in natural populations, the principles and mechanisms of evolutionary change, the interpretation of genetic data from natural populations, and how these can be applied to conservation. The book includes examples from plants, animals, and microbes in wild and captive populations. This second edition contains new chapters on Climate Change and Exploited Populations as well as new sections on genomics, genetic monitoring, emerging diseases, metagenomics, and more. One-third of the references in this edition were published after the first edition. Each of the 22 chapters and the statistical appendix have a Guest Box written by an expert in that particular topic (including James Crow, Louis Bernatchez, Loren Rieseberg, Rick Shine, and Lisette Waits). This book is essential for advanced undergraduate and graduate students of conservation genetics, natural resource management, and conservation biology, as well as professional conservation biologists working for wildlife and habitat management agencies. Additional resources for this book can be found at: www.wiley.com/go/allendorf/populations.
Whether referring to a place, a nonhuman animal or plant, or a state of mind, wild indicates autonomy and agency, a will to be, a unique expression of life. Yet two contrasting ideas about wild nature permeate contemporary discussions: either that nature is most wild in the absence of a defiling human presence, or that nature is completely humanized and nothing is truly wild. This book charts a different path. Exploring how people can become attuned to the wild community of life and also contribute to the well-being of the wild places in which we live, work, and play, Wildness brings together esteemed authors from a variety of landscapes, cultures, and backgrounds to share their stories about the interdependence of everyday human lifeways and wildness. As they show, far from being an all or nothing proposition, wildness exists in variations and degrees that range from cultivated soils to multigenerational forests to sunflowers pushing through cracks in a city alley. Spanning diverse geographies, these essays celebrate the continuum of wildness, revealing the many ways in which human communities can nurture, adapt to, and thrive alongside their wild nonhuman kin. From the contoured lands of Wisconsin's Driftless region to remote Alaska, from the amazing adaptations of animals and plants living in the concrete jungle to indigenous lands and harvest ceremonies, from backyards to reclaimed urban industrial sites, from microcosms to bioregions and atmospheres, manifestations of wildness are everywhere. With this book, we gain insight into what wildness is and could be, as well as how it might be recovered in our lives and with it, how we might unearth a more profound, wilder understanding of what it means to be human.
'How glorious a greeting the sun gives the mountains! To behold this alone is worth the pains of any excursion a thousand times over.' John Muir is known internationally for his dedication to protecting the environment and for founding The Sierra Club in 1892. His first book, as Muir authority Terry Gifford writes in the foreword, 'became the bible of the fledgling Sierra Club, which is now a major national environmental activists' organisation with branches in every corner of America'. The Mountains of California not only details Muir's visits to the magnificent mountains along the Sierra Nevada Range, which he affectionately calls 'The Range of Light', but also the stunning glaciers, forests and landscapes that he encounters: 'Climbing higher, I saw for the first time the gradual dwarfing of the pines in compliance with climate ... patches of the dwarf vaccinium with its round flowers sprinkled in the grass like purple hail; while in every direction the landscape stretched sublimely away in fresh wildness: a manuscript written by the hand of nature alone.' Throughout the book, Muir's philosophy of nature's ability to soothe and amaze is evident. He heart-warmingly discusses at length how his encounters with animals, such as the Douglas squirrel, cheered him so. This is a truly beautiful read; Muir's writing, embedded with emotion, wit, and at times, humour, will never fail to speak to his reader. The enthusiasm contained within these pages is infectious, and as well as making a powerful read, Muir will inspire you, too, to 'come and see' the innumerable delights that nature can offer: 'The best words only hint at [California's] charms. Come to the mountains and see.' |
