The conservation movement is moving rapidly away from traditional "protectionist" approaches toward nature to more integrated views of wildlife and landscape conservation. This volume reviews modern conservation approaches as they relate to mammals. A team of researchers and conservationists provide focused perspectives on preservation, such as the role of mammals within the conservation movement, how priorities should be set, allocation of funds, and promising techniques and approaches for future mammal protection. In addition, issues of broader conservation relevance are highlighted, including the integration of species and biodiversity approaches, the role of "flagship species," and the need for holistic conservation models in the wider context of society and government.
This book explores the politics of wildlife conservation policy in Africa, specifically Zambia, Kenya, and Zimbabwe. The book addresses a general question: Why don't wildlife policies seem to be working? Rather than use standard explanations such as "bureaucratic inefficiency" or "corrupt dictators," the book demonstrates how politicians at all levels use wildlife policy for their own political ends, which may or may not include conservation. The book uses electoral and archival data, as well as interviews with individuals ranging from presidents to poachers to address this issue.
Although wildlife fascinates citizens of industrialized countries, little is known about the politics of wildlife policy in Africa. In this innovative book, Clark Gibson challenges the rhetoric of television documentaries and conservation organizations to explore the politics behind the creation and change of wildlife policy in Africa. This book examines what Clark views as a central puzzle in the debate: Why do African governments create policies that apparently fail to protect wildlife? Moving beyond explanations of bureaucratic inefficiency and corrupt dictatorships, Gibson argues that biologically disastrous policies are retained because they meet the distributive goals of politicians and bureaucrats. Using evidence from Zambia, Kenya, and Zimbabwe, Gibson shows how institutions encourage politicians and bureaucrats to construct wildlife policies that further their own interests. Different configurations of electoral laws, legislatures, party structures, interest groups, and traditional authorities in each country shape the choices of policymakers - many of which are not consonant with conservation. This book will appeal to students of institutions, comparative politics, natural resource policymaking, African politics, and wildlife conservationists.
The Bears Ears National Monument in southeastern Utah, created by President Obama in 2016 and eviscerated by the Trump administration in 2017, contains more archaeological sites than any other region in the United States. It’s also a spectacularly beautiful landscape, a mosaic of sandstone canyons and bold mesas and buttes. This wilderness, now threatened by oil and gas drilling, unrestricted grazing, and invasion by Jeep and ATV, is at the center of the greatest environmental battle in America since the damming of the Colorado River to create Lake Powell in the 1950s. In The Bears Ears, acclaimed adventure writer David Roberts takes readers on a tour of his favorite place on earth as he unfolds the rich and contradictory human history of the 1.35 million acres of the Bears Ears domain. Weaving personal memoir with archival research, Roberts sings the praises of the outback he’s explored for the last twenty-five years.
Once described by the actress, Joanna Lumley, as "the man with no fear", Tristan Voorspuy spent his whole life living up to the legend. Early stints in Northern Ireland and Germany with the Blues and Royals regiment were but a precursor to a life defined by his love of Africa, a life cut tragically short in 2017 on his beloved game reserve, Sosian. From his epic motorbike ride from Cairo to Cape Town, to extraordinary wildlife encounters and many death-defying light aircraft near misses, Life on the Edge paints a picture of a man determined to live life to the full. It is also the story of compassion, conservation and, ultimately, tragedy. In the last two decades of his life, Voorspuy transformed the overgrazed and drought-blighted Sosian ranch in Northern Kenya into a celebrated game reserve, acclaimed tourist destination and successful cattle ranch. True to form, it was whilst defending this property that an unarmed Tristan, on horseback, was gunned down and killed, a murder that sent shockwaves around the world.
Australia's varied grasslands have suffered massive losses and changes since European settlement, and those changes continue under increasingly intensive human pressures for development and agricultural production. The values of native grasslands for conservation of endemic native biodiversity, both flora and fauna, have led to strong interests in the protection of remaining fragments, especially near urban centres, and documentation of the insects and other inhabitants of grasslands spanning tropical to cool temperate parts of the country. Attention to conservation of grassland insects in Australia is relatively recent, but it is increasingly apparent that grasslands harbour many localised and ecologically specialised endemic species. Their conservation necessarily advances from very incomplete documentation, and draws heavily on lessons from the far better-documented grasslands elsewhere, most notably in the northern hemisphere, and undertaken over far longer periods. From those cases, and the extensive background to grassland management to harmonise conservation with production and amenity values through honing use of processes such as grazing, mowing and fire, the needs and priorities for Australia can become clearer, together with needs for grassland restoration at a variety of scales. This book is a broad overview of conservation needs of grassland insects in Australia, drawing on the background provided elsewhere in the world on the responses to disturbances, and the ecological importance, of some key insect groups (notably Orthoptera, Hemiptera and Lepidoptera) to suggest how insect conservation in native, pastoral and urban grasslands may be advanced. The substantial references given for each chapter facilitate entry for non-entomologist grassland managers and stewards to appreciate the diversity and importance of Australia's grassland insects, their vulnerabilities to changes, and the possibilities for conserving them and the wider ecological roles in which they participate.
Domestic and wild large mammalian herbivores occur on every continent except Antarctica. Through their browsing and grazing, they affect the structure and distribution not only of vegetation, but also of associated fauna. Consequently, the interactions between management practices and herbivore populations influence the biodiversity, structure and dynamics of ecosystems across vast expanses around the globe: signs of human activity that will be detectable for epochs to come. As a follow-up work to The Ecology of Browsing and Grazing, published in 2008, this new volume presents cutting-edge research on the behaviour, distribution, movement, and direct and indirect impacts of domestic and wild herbivores on terrestrial ecosystems. The respective chapters highlight strategic and applied research on cross-cutting issues in palaeontology and ecology, and provide concrete recommendations on the management of large herbivores to integrate production and conservation in terrestrial systems. Given its scope, the book will appeal to students, researchers and anyone interested in understanding these fascinating wild animals and how they shape the natural world.
The most up-to-date and authoritative resource on the biology and evolution of solitary bees While social bees such as honey bees and bumble bees are familiar to most people, they comprise less than 10 percent of all bee species in the world. The vast majority of bees lead solitary lives, surviving without the help of a hive and using their own resources to fend off danger and protect their offspring. This book draws on new research to provide a comprehensive and authoritative overview of solitary bee biology, offering an unparalleled look at these remarkable insects. The Solitary Bees uses a modern phylogenetic framework to shed new light on the life histories and evolution of solitary bees. It explains the foraging behavior of solitary bees, their development, and competitive mating tactics. The book describes how they construct complex nests using an amazing variety of substrates and materials, and how solitary bees have co-opted beneficial mites, nematodes, and fungi to provide safe environments for their brood. It looks at how they have evolved intimate partnerships with flowering plants and examines their associations with predators, parasites, microbes, and other bees. This up-to-date synthesis of solitary bee biology is an essential resource for students and researchers, one that paves the way for future scholarship on the subject. Beautifully illustrated throughout, The Solitary Bees also documents the critical role solitary bees play as crop pollinators, and raises awareness of the dire threats they face, from habitat loss and climate change to pesticides, pathogens, parasites, and invasive species.
As the human impact on the earth leads to ever increasing environmental degradation, the restoration of dwindling populations of numerous plant and animal species has become urgent. In this volume, contributors examine the conceptual, planning, and applied aspects of recovery of rare or endangered species. It is unique in its treatment of both plants and animals, and in its presentation of scientific approaches to implemented restorations. Experts report on the restoration efforts and plans for the restoration of a wide variety of species including the dune thistle, lakeside daisy, woodland caribou, kit fox, and black-footed ferret and end with a broad overview, suggesting future opportunities and problems.
Population genomics has provided unprecedented opportunities to unravel the mysteries of marine organisms in the oceans' depths. The world's oceans, which make up 70% of our planet, encompass diverse habitats and host numerous unexplored populations and species. Population genomics studies of marine organisms are rapidly emerging and have the potential to transform our understanding of marine populations, species, and ecosystems, providing insights into how these organisms are evolving and how they respond to different stimuli and environments. This knowledge is critical for understanding the fundamental aspects of marine life, how marine organisms will respond to environmental changes, and how we can better protect and preserve marine biodiversity and resources. This book brings together leading experts in the field to address critical aspects of fundamental and applied research in marine species and share their research and insights crucial for understanding marine ecosystem diversity and function. It also discusses the challenges, opportunities and future perspectives of marine population genomics.
It is more than a thousand years since the exploitation of the elephant began.
'Divine beauty all. Here I could stay tethered forever with just bread and water, nor would I be lonely.' In the summer of 1869, John Muir joined a group of shepherds in the foothills of California's Sierra Nevada mountains, that he might study and expand his knowledge of the plants, animals and rocks he found there. My First Summer in the Sierra - first published in 1911 - is the detailed and colourful diary he kept while tending sheep and exploring the wilderness. Muir's account tracks his experiences in the Yosemite Valley and the High Sierra alongside faithful companion Carlo the St Bernard, describing the majestic landscapes and the flora and fauna of the area with the excitement and wonder of a child. From sleeping on silver-fir-bough mattresses to goading wild bears, and valuing everything from tiny pebbles to giant sequoia, he truly immerses himself and falls in love with the wilderness. Muir's enthusiasm is infectious, and over 100 years on his environmental message is more pertinent than ever. With a new introduction from Muir authority Terry Gifford, My First Summer in the Sierra is an enchanting and informative read for anyone passionate about the natural world and its splendours.
As it becomes ever more expensive to purchase land for conservation purposes, it is becoming increasingly important both to manage existing sites properly and to create new habitats. This comprehensive volume provides a pragmatic, habitat-by-habitat guide to conservation management, in which the prescriptions and methods are based on sound science coupled with practical experience. For each habitat, the book guides the reader through the options and solutions, highlights potential problems, and gives good and bad examples of habitat management in the past. This will be required reading for all practicing ecologists, land managers, wardens, landscape architects and conservationists, and will provide a valuable reference for students of ecology, conservation and environmental science.
This second edition emphasizes the environmental impact on reproduction, with updated chapters throughout as well as complete new chapters on species such as sharks and rays. This is a wide-ranging book that will be of relevance to anyone involved in species conservation, and provides critical perspectives on the real utility of current and emerging reproductive sciences.Understanding reproductive biology is centrally important to the way many of the world's conservation problems should be tackled. Currently the extinction problem is huge, with up to 30% of the world's fauna being expected to disappear in the next 50 years. Nevertheless, it has been estimated that the global population of animals in zoos encompasses 12,000 - 15,000 species, and we anticipate that every effort will be made to preserve these species for as long as possible, minimizing inbreeding effects and providing the best welfare standards available. Even if the reproductive biology community cannot solve the global biodiversity crisis for all wild species, we should do our best to maintain important captive populations. Reproductive biology in this context is much more than the development of techniques for helping with too little or too much breeding. While some of the relevant techniques are useful for individual species that society might target for a variety of reasons, whether nationalistic, cultural or practical, technical developments have to be backed up by thorough biological understanding of the background behind the problems.
This book describes the natural processes that must be understood in order to manage and protect the Earth's biological diversity. The author begins with a clear definition of biological diversity and a summary of the types of diversity patterns found on Earth. Next he lays out a scientific framework for understanding the complex array of diversity patterns, including the distribution of rare species to landscape patterns visible from space. Many fascinating case studies of coral reefs, fire-maintained shrublands, prairies, and tropical rain forests illustrate the theories and models described in this book, including such fundamental issues as endemism, invasions, and extinction in temperate, tropical, and marine ecosystems.
This book sheds light on the major functions of microbial communities in aquaculture ecosystems, showing that by recycling nutrients, degrading organic matter and preventing disease outbreaks, a variety of microbes are truly beneficial to a wide range of aquaculture industries. It discusses how deteriorating environmental quality enables some microbial strains to trigger disease, describes the development of highly sustainable tools to improve water quality, and identifies crucial factors that endanger microbial homeostasis in aquaculture ecosystems. The book also covers post-antibiotic approaches for preventing and treating opportunistic microbial infections based on harnessing environmental and fish-associated microbial communities. Furthermore, it explores how manipulating and engineering these complex microbial communities using bio-agents such as probiotics, phages, natural nutritional additives, or with fine-tuned biofilters will open the door for new ways to develop a more sustainable and cost-effective aquaculture industry. Including an accessible presentation of modern high-throughput sequencing technology to identify host-microbial interactions in aquaculture ecosystems, this book is a valuable resource for scientists, aquaculture and fishery experts, sustainability enthusiasts and scholars in the areas of biology and marine agriculture.
Since the first edition of this book published in 2005, there has been an immense amount of new and fascinating work on the history, ecology, and evolution of the Mediterranean flora. During this time, human impacts have continued to increase dramatically, significantly influencing both the ecology and evolution of the region's biota. This timely and comprehensive update of the original text integrates a diverse and scattered literature to produce a synthetic account of Mediterranean plant evolutionary ecology. It maintains the accessible style of its previous version whilst incorporating recent work in a new structural framework. This is not a traditional "plant science" book per se, but a novel integration of history, ecology, biogeography, and evolution, all set in the context of a dramatically increasing human footprint. There is a particular emphasis on the role of human activities as an ecological factor and their subsequent impact on plant evolution. Conversely, it demonstrates how an understanding of the evolutionary ecology of the region's flora can be used to provide insights into its future conservation and management. Plant Evolution in the Mediterranean is aimed at all those who are interested in the biology of the Mediterranean region, whether it is taxonomy, ecology, evolution, conservation policy and management, or the regional history of its biodiversity in general. It will be of relevance and use to all graduate students and researchers of Mediterranean-type ecosystem ecology and geography, as well as professional ecologists, evolutionary biologists, conservation biologists, and environmental practitioners requiring a concise, authoritative overview of the topic.
This groundbreaking book is a contemporary global synthesis of the rapidly developing and important field of insect conservation biology. Insects play important roles in terrestrial ecological processes and in maintaining the world as we know it. They present particular conservation challenges, especially as a quarter face extinction within the next few decades. This textbook addresses the ethical foundation of insect conservation, and asks why should we concern ourselves with conservation of a butterfly, beetle or bug? The success of insects and their diversity, which have survived glaciers, is now facing a more formidable obstacle: the meteoric impact of humans. After addressing threats, from invasive alien plants to climate change, the book explores ways insects and their habitats are prioritised, mapped, monitored and conserved. Landscape and species approaches are considered. This book is for undergraduates, postgraduates, researchers and managers in conservation biology or entomology, and the wider biological and environmental sciences.
This book highlights the fundamental association between aquaculture and engineering in classifying fish hunger behaviour by means of machine learning techniques. Understanding the underlying factors that affect fish growth is essential, since they have implications for higher productivity in fish farms. Computer vision and machine learning techniques make it possible to quantify the subjective perception of hunger behaviour and so allow food to be provided as necessary. The book analyses the conceptual framework of motion tracking, feeding schedule and prediction classifiers in order to classify the hunger state, and proposes a system comprising an automated feeder system, image-processing module, as well as machine learning classifiers. Furthermore, the system substitutes conventional, complex modelling techniques with a robust, artificial intelligence approach. The findings presented are of interest to researchers, fish farmers, and aquaculture technologist wanting to gain insights into the productivity of fish and fish behaviour.
This book provides a new inter-disciplinary look at the practice and policies of conservation in Africa. Bringing together social scientists, anthropologists and historians with biologists for the first time, the book sheds some light on the previously neglected but critically important social aspects of conservation thinking. To date conservation has been very much the domain of the biologist, but the current ecological crisis in Africa and the failure of orthodox conservation policies demand a radical new appraisal of conventional practices. This new approach to conservation, the book argues, cannot deal simply with the survival of species and habitats, for the future of African wildlife is intimately tied to the future of African rural communities. Conservation must form an integral part of future policies for human development. The book emphasises this urgent need for a complementary rather than a competitive approach. It covers a wide range of topics important to this new approach, from wildlife management to soil conservation and from the Cape in the nineteenth century to Ethiopia in the 1980s. It is essential reading for all those concerned about people and conservation in Africa.

Tortoises, those unmistakable turtles, evolved from a lineage that split off from the familiar pond turtles roughly 100 million years ago. Over time, these plant-eating land turtles spread around the world, growing to an enormous size (depending on the species) and living so long that they have become the stuff of legends. By most accounts, they are indeed the longest-lived of the turtles, with good records suggesting individuals may live as long as 180 years (anecdotal records suggest that some reach ages of 200 years or more). Providing the first comprehensive treatment of North America's tortoises, Biology and Conservation of North American Tortoises brings together leading experts to give an overview of tortoise morphology, taxonomy, systematics, paleontology, physiology, ecology, behavior, reproduction, diet, growth, health, and conservation. The contributors carefully combine their own expertise and observations with results from studies conducted by hundreds of other researchers. The result is a book that belongs in the library of every herpetologist. Contributors include: Gustavo Aguirre; L. Linda; J. Allison Matthew; J. Aresco Roy; C. Averill-Murray; Joan E. Berish; Kristin H. Berry; Dennis M. Bramble; K. Kristina Drake; Taylor Edwards; Todd C. Esque; Richard Franz; Craig Guyer; J. Scott Harrison; Sharon M. Hermann; J. Howard Hutchison; Elliott R.

'BRITAIN'S FINEST LIVING NATURE WRITER' - THE TIMES A SUNDAY TIMES BESTSELLER and BBC Radio 4 'Book of the Week' from 'indisputably, one of the best nature-writers of his generation' (Country Life) Written in diary format, The Wood is the story of English woodlands as they change with the seasons. Lyrical and informative, steeped in poetry and folklore, The Wood inhabits the mind and touches the soul. For four years John Lewis-Stempel managed Cockshutt wood, a particular wood - three and half acres of mixed woodland in south west Herefordshire - that stands as exemplar for all the small woods of England. John coppiced the trees and raised cows and pigs who roamed free there. This is the diary of the last year, by which time he had come to know it from the bottom of its beech roots to the tip of its oaks, and to know all the animals that lived there - the fox, the pheasants, the wood mice, the tawny owl - and where the best bluebells grew. For many fauna and flora, woods like Cockshutt are the last refuge. It proves a sanctuary for John too. To read The Wood is to be amongst its trees as the seasons change, following an easy path until, suddenly the view is broken by a screen of leaves, or your foot catches on a root, or a bird startles overhead. This is a wood you will never want to leave.
Clifton Bain now completes his trilogy with this look at the Peatlands of Britain and Ireland. A source of fuel for many generations, they are now a haven for wildlife and plants as well as a storehouse of greenhouse gasses. Their social history is one of exploitation and the value of mending and restoring is a major theme of the book. Like its predecessors, The Peatlands of Britain and Ireland will be a sumptuous volume richly illustrated with photographs and with drawings by the wildlife artist Darren Rees.
