This book is also available in paperback. What is it like to rehabilitate sun bears in the rainforests of Malaysia? Why are sloth bears trained to dance? How is traditional Chinese medicine implicated in the deaths of black bears in North America? Bear Necessities answers all of these questions, and many more. Through the voices of activists, scientists, and educators, readers walk alongside those who pull sun bears from Vietnamese bile farms, track Andean bears in the rugged hills of Ecuador, work to protect Montana's grizzlies in the courtroom, and gently heal the many wounded bears who live in sanctuaries around the world. Though almost every bear species is endangered or severely threatened, Bear Necessities offers hope through knowledge and understanding, which reside at the heart of change.

The analysis of meat and its place in Western culture has been central to Human-Animal Studies as a field. It is even more urgent now as global meat and dairy production are projected to rise dramatically by 2050. While the term 'carnism' denotes the invisible belief system (or ideology) that naturalizes and normalizes meat consumption, in this volume we focus on 'meat culture', which refers to all the tangible and practical forms through which carnist ideology is expressed and lived. Featuring new work from leading Australasian, European and North American scholars, Meat Culture, edited by Annie Potts, interrogates the representations and discourses, practices and behaviours, diets and tastes that generate shared beliefs about, perspectives on and experiences of meat in the 21st century.

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.

In Wild Winter, John D. Burns, bestselling author of The Last Hillwalker and Bothy Tales, sets out to rediscover Scotland's mountains, remote places and wildlife in the darkest and stormiest months. He traverses the country from the mouth of the River Ness to the Isle of Mull, from remote Sutherland to the Cairngorms, in search of rutting red deer, pupping seals, minke whales, beavers, pine martens, mountain hares and otters. In the midst of the fierce weather, John's travels reveal a habitat in crisis, and many of these wild creatures prove elusive as they cling on to life in the challenging Highland landscape. As John heads deeper into the winter, he notices the land fighting back with signs of regeneration. He finds lost bothies, old friendships and innovative rewilding projects, and - as Covid locks down the nation - reflects on what the outdoors means to hillwalkers, naturalists and the folk who make their home in the Highlands. Wild Winter is a reminder of the wonder of nature and the importance of caring for our environment. In his winter journey through the mountains and bothies of the Highlands, John finds adventure, humour and a deep sense of connection with this wild land.

Spring is nature's season of rebirth and rejuvenation. Earth's northern hemisphere tilts towards the sun, winter yields to intensifying light and warmth, and a wild, elemental beauty transforms the Highland landscape and a repertoire of islands from Colonsay to Lindisfarne. Jim Crumley chronicles the wonder, tumult and spectacle of that transformation, but he shows too that it is no Wordsworthian idyll that unfolds. Climate chaos brings unwanted drama to the lives of badger and fox, seal and seabird and raptor, pine marten and sand martin. Jim lays bare the impact of global warming and urges us all towards a more daring conservation vision that embraces everything from the mountain treeline to a second spring for the wolf.

"Diagnosing Wild Species Harvest" bridges gaps of knowledge fragmented among scientific disciplines as it addresses this multifaceted phenomenon that is simultaneously global and local. The authors emphasize the interwoven nature of issues specific to the ecological, economic, and socio-cultural realms of wild species harvest.

The book presents the diagnosing wild species harvest procedure as a universal approach that integrates seven thematic perspectives to harvest systems: resource dynamics, costs and benefits, management, governance, knowledge, spatiality, and legacies. When analyzed, these themes help to build a holistic understanding of this globally important phenomenon. Scholars, professionals and students in various fields related to natural resources will find the book a valuable resource.

Wild species form important resources for people worldwide, and their harvest is a major driver of ecosystem change. Tropical forests regions, including Amazonia, are among those parts of the world where wild species are particularly important for people's livelihoods and larger economies. This book draws on tangible experiences from Amazonia, presented in lively narratives intermingling scientific information with stories of the people engaged in harvest and management of wild species. These stories are linked to relevant theory of wild species harvest and wider discussions on conservation, development, and the global quest of sustainability.
Includes research and report-style narratives describing a wide variety of concrete casesAddresses wild species harvest from a holistic perspective including ecological, economic and socio-cultural issues, not limiting the scope to a single type of resourcesProvides theoretical treatment of wild species harvest worldwide, with special emphasis in the most recent scientific understanding on the biodiversity of the Amazonian lowland regionPresents an objective viewpoint, noting problems the harvest may cause as well as its potential to contribute both to biodiversity conservation and to local livelihoods and national economiesCoherent, easily followed structure and abundant illustrations help the reader absorb central messages

Today, the East African state of Tanzania is renowned for wildlife preserves such as the Serengeti National Park, the Ngorongoro Conservation Area, and the Selous Game Reserve. Yet few know that most of these initiatives emerged from decades of German colonial rule. This book gives the first full account of Tanzanian wildlife conservation up until World War I, focusing upon elephant hunting and the ivory trade as vital factors in a shift from exploitation to preservation that increasingly excluded indigenous Africans. Analyzing the formative interactions between colonial governance and the natural world, The Nature of German Imperialism situates East African wildlife policies within the global emergence of conservationist sensibilities around 1900.

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.

This book addresses the impacts of current and future reproductive technologies on our world food production and provides a significant contribution to the importance of research in the area of reproductive physiology that has never been compiled before. It would provide a unique opportunity to separate the impacts of how reproductive technologies have affected different species and their contributions to food production. Lastly, no publication has been compiled that demonstrates the relationship between developments in reproductive management tools and food production that may be used a reference for scientists in addressing future research areas. During the past 50 years assisted reproductive technologies have been developed and refined to increase the number and quality of offspring from genetically superior farm animal livestock species. Artificial insemination (AI), estrous synchronization and fixed-time AI, semen and embryo cryopreservation, multiple ovulation and embryo transfer (MOET), in vitro fertilization, sex determination of sperm or embryos, and nuclear transfer are technologies that are used to enhance the production efficiency of livestock species.

Federal Twist is set on a ridge above the Delaware River in western New Jersey, USA. It is a naturalistic garden that has loose boundaries and integrates closely with the natural world that surrounds it. It has no utilitarian or leisure uses (no play areas, swimming pools or outdoor dining) and the site is not an obvious choice for a garden (heavy clay soil, poorly drained: quick death for any plants not ecologically suited to it). The physical garden, its plants and its features, is of course an appealing and pleasant place to be but Federal Twist's real charm and significance lie in its intangible aspects: its changing qualities and views, the moods and emotions it evokes, and its distinctive character and sense of place. Monty Don commented after his visit, "it made me rethink what a garden can be and do." This book charts the author's journey in making such a garden. How he made a conscious decision not to "improve the land", planted large, competitive plants into rough grass, experimented with seeding to develop sustainable plant communities. And how he worked with light to provoke certain moods and allowed the energy of the place, chance and randomness to have its say. Part experimental horticulturist and part philosopher, James Golden has written an important book for naturalistic and ecological gardeners and anyone interested in exploring the relationship between gardens, nature and ourselves.

Rock iguanas of the West Indies are considered to be the most endangered group of lizards in the world. They are a flagship species in the Caribbean and on most islands are the largest native land animals. Unfortunately, human encroachment and introduced animals have brought this species to the brink of extinction. "Cyclura: Natural History, Husbandry, and Conservation of the West Indian Iguanas" is the first book to combine the natural history and captive husbandry of these remarkable reptiles, while at the same time outlining the problems researchers and conservationists are battling to save these beautiful, iconic animals of the Caribbean islands.

Authors Jeffrey Lemm and Allison Alberts have been studying West Indian iguanas for nearly 20 years in the wild and in captivity; their experiences with wild iguanas and their exquisite photos of these charismatic lizards in the wild make this book a must-have for reptile researchers, academics and enthusiasts, as well as anyone interested in nature and conservation.
Includes chapters with contributions by leading experts on rock iguana taxonomy, nutrition, and diseases Features color photos of all taxa, including habitat and captive shotsProvides easily understandable and usable information gleaned from experience and hands-on reptile research

The unexpected and fascinating interspecies relationship between humans and horseshoe crabs. Horseshoe crabs are considered both a prehistoric and indicator species. They have not changed in tens of millions of years and provide useful data to scientists who monitor the health of the environment. From the pharmaceutical industry to paleontologists to the fishing industry, the horseshoe crab has made vast, but largely unknown, contributions to human life and our shared ecosystem. Catch and Release examines how these intersections steer the trajectory of both species' lives, and futures. Based on interviews with conservationists, field biologists, ecologists, and paleontologists over three years of fieldwork on urban beaches, noted ethnographer Lisa Jean Moore shows how humans literally harvest the life out of the horseshoe crabs. We use them as markers for understanding geologic time, collect them for agricultural fertilizer, and eat them as delicacies, capture them as bait, then rescue them for conservation, and categorize them as endangered. The book details the biomedical bleeding of crabs; how they are caught, drained of 40% of their blood, and then released back into their habitat. The model of catch and release is essential. Horseshoe crabs cannot be bred in captivity and can only survive in their own ecosystems. Moore shows how horseshoe crabs are used as an exploitable resource, and are now considered a "vulnerable" species. An investigation of how humans approach animals that are essential for their survival, Catch and Release questions whether humans should have divine, moral, or ethical claims to any living being in their path.

Habitat fragmentation and global climate change are the two major environmental threats to the persistence of species and ecosystems. The probability of a species surviving such changes is strongly dependent on its ability to track shifts in the environmental, either by moving between patches of habitat or by rapidly adapting to local condition. These 'solutions' to problems posed by environmental change depend on dispersal propensity, motivating our desire to better understand this important behavior. This book is a comprehensive overview of the new developments in the study of dispersal and the state-of-the-art research on the evolution of this trait. The causes, mechanisms, and consequences of dispersal at the individual, population, and species levels are considered. The promise of new techniques and models for studying dispersal, drawn from molecular biology and demography is explored. Perspectives on the study of dispersal are offered from evolution, conservation biology, and genetics. Throughout the book, theoretical approaches are combined with empirical data, and examples are included from as wide a range of species as possible.

NICOLA CHESTER - A visit to the rapid where she lost a cherished friend unexpectedly reignites Amy-Jane Beer’s love of rivers setting her on a journey of natural, cultural and emotional discovery. On New Year’s Day 2012, Amy-Jane Beer’s beloved friend Kate set out with a group of others to kayak the River Rawthey in Cumbria. Kate never came home, and her death left her devoted family and friends bereft and unmoored. Returning to visit the Rawthey years later, Amy realises how much she misses the connection to the natural world she always felt when on or close to rivers, and so begins a new phase of exploration. The Flow is a book about water, and, like water, it meanders, cascades and percolates through many lives, landscapes and stories. From West Country torrents to Levels and Fens, rocky Welsh canyons, the salmon highways of Scotland and the chalk rivers of the Yorkshire Wolds, Amy-Jane follows springs, streams and rivers to explore tributary themes of wildness and wonder, loss and healing, mythology and history, cyclicity and transformation. Threading together places and voices from across Britain, The Flow is a profound, immersive exploration of our personal and ecological place in nature.
