Beyond The Secret Elephants is the continuing story of Gareth Patterson’s almost two decades of research into the secretive Knysna elephants. Significantly, however, it also reveals his startling discovery of a much more mysterious being than the elephants – a relict hominoid known to the indigenous forest people as the Otang. Gareth had long heard about the existence of the otang from the local people but he mentioned it only briefly in The Secret Elephants, focusing instead on his rediscovery of the Knysna elephants and their survival against the odds. He was reluctant to blur the story of the elephants with his findings about the otang. That is, until now. The possible existence of relict hominoids is today gaining momentum worldwide with ongoing research into Bigfoot in North America, the Yeti in the Himalayas and the Orang Pendek in Sumatra. Eminent conservationists and scientists – among them Dr Jane Goodall, Dr George Schaller and Professor Jeff Meldrum – have publicly stated that they are open-minded about the possible existence of these cryptid beings. In the course of his unannounced research into the otang Gareth heard many accounts – mostly spontaneous and unprompted – of otang sightings by others in the area over a number of years. These accounts, documented in the book, are astonishingly consistent both in the descriptions of the otang and in the shocked reactions of the individuals who saw them. Gareth Patterson’s work supports the increasing realisation that humankind still has much to learn about the natural world and the mysteries it holds. The possibility that we may be sharing our world with other as yet unidentified hominoids is today being viewed as something that should not be discounted. And as humankind, we need to reassess our role and our responsibility towards all forms of life that coexist with us on planet Earth.
This book examines the reintroduction and recovery of the wolf in the Northern Rocky Mountains. The wolf was driven to brink of extinction through conscious government policy. The Endangered Species Act of 1973 provided the means for wolf's return, which began in the Carter administration and continues in the Obama administration. The battle over the wolf is part of a larger struggle over the management of public lands, generating public law litigation. Interest groups brought suit in federal courts, challenging the Department of Interior's implementation of policy. The federal courts were required to interpret the statutory mandates and review Interior's decisions to insure statutory compliance. The analysis of this public law litigation demonstrates that the federal courts correctly interpreted the statutory mandates and properly supported and checked Interior's decisions. This book focuses on the controversial role of the courts in the resolution of public policy conflicts. Judicial skeptics argue that the courts should not get involved in complex public policy disputes as Judges lack the expertise and information to make informed decisions. Judicial proponents, by contrast, argue that judicial involvement is necessary so Federal courts can oversee federal agencies, which are under conflicting pressure from interest groups, the President, Congress, and their own internal dynamics. This book supports the conclusions of judicial proponents and points out that the federal courts have been instrumental in the return and recovery of the wolf to the Northern Rocky Mountains.
Everyone is familiar with the dodo and the wooly mammoth, but how many people have heard of the scimitar cat and the Falkland Island fox? "Extinct Animals" portrays over 60 remarkable animals that have been lost forever during the relatively recent geological past. Each entry provides a concise discussion of the history of the animal--how and where it lived, and how it became extinct--as well as the scientific discovery and analysis of the creature. In addition, this work examines what led to extinction--from the role of cyclical swings in the Earth's climate to the spread of humans and their activities. Many scientists believe that we are in the middle of a mass extinction right now, caused by the human undermining of the earth's complex systems that support life. Understanding what caused the extinction of animals in the past may help us understand and prevent the extinction of species in the future. "Extinct Animals" examines the biology and history of some of the most interesting creatures that have ever lived, including: The American Terror Bird, which probably became extinct over 1 million years ago, who were massive predators, some of which were almost 10 feet tall; the Rocky Mountain Locust, last seen in 1902, formed the most immense animal aggregations ever known, with swarms estimated to include over 10 trillion insects; the Giant Ground Sloth, which was as large as an elephant; and the Neandertals, the first Europeans, which co-existed with prehistoric Homo sapiens. "Extinct Animals" includes illustrations--many created for the work--that help the reader visualize the extinct creature, and each entry concludes with a list of resources for those who wish to do further research.

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.
This book analyzes empirical data from three specific Regional Fisheries Management Organizations (RFMOs) designed to establish rules for the conservation and management of fish stocks in the ocean, in order to assess their effectiveness in converting science into policy for the recovery and maintenance of fishery populations. The three RFMOs discussed are the CCAMLR (Convention for the Conservation of Antarctic Marine Living Resources), the ICCAT (International Commission for the Conservation of Atlantic Tunas) and the CCSBT (Commission for the Conservation of Southern Bluefin Tuna). The book seeks to understand when governments choose to listen to science, and establishes a framework to examine the institutional designs currently in place to accommodate RFMO policy suggestions and the conditions under which they are implemented successfully. The study will be of interest to academics and professionals broadly interested in global environmental governance and international relations, and will specifically appeal to policymakers, conservationists, and environmental researchers interested in fishery management and policy at the global and regional scale. Goncalves provides an accessible and comprehensive analysis of RMFOs. She offers valuable insights into the role of science and politics in shaping sustainable fisheries policies for the open oceans. ---Peter M Haas, Professor Department of Political Science, University of Massachusetts Amherst As envisaged by the UN Decade of Ocean proclamation, this book is an important and sincere effort, hopefully to be accompanied by many others to come during this promising decade, that will help to build a common framework to ensure that ocean science can support countries and the international community in creating improved conditions for the sustainable development of our cherished Ocean. ---Fabio H. Hazin - Professor at Federal Rural University of Pernambuco, Brazil
An exhilarating journey to some of the world's most stunning locales, led by one of conservation's key scientists. In 1972, Eric Dinerstein was in film school at Northwestern University, with few thoughts of nature, let alone tiger-filled jungles at the base of the Himalayas or the antelope-studded Serengeti plain. Yet thanks to some inspiring teachers and the squawk of a little green heron that awakened him to nature's fundamental wonders, Dinerstein would ultimately become a leading conservation biologist, traveling to these and other remote corners of the world to protect creatures ranging from the striking snow leopard to the homely wrinkle-faced bat. "Tigerland and Other Unintended Destinations" takes readers on Dinerstein's unlikely journey to conservation's frontiers, from early research in Nepal to recent expeditions as head of Conservation Science at the World Wildlife Fund. Along the way, each locale is brought to life by the author's vivid descriptions, amusing stories, and poetic voice. We are there as the author renews his resolve after being swept downstream on an elephant's back, tracks snow leopards in the mountains of Kashmir with a remarkable housewife turned zoologist, and finds unexpected grit in a Manhattanite donor he guides into the wildest reaches of the Orinoco River. At every turn, we meet professed and unprofessed ecologists who share Dinerstein's mission, a cast of free-spirited characters uncommonly committed to - and remarkably successful at - preserving slices of the world's natural heritage. A simple sense of responsibility, one feels, shines through all of Dinerstein's experiences: not just to marvel at what we see, but to join in efforts to sustain the planet's exquisite design. Tigerland's message is clear: individuals make all the difference; if we combine science, advocacy, and passion, ambitious visions for conservation can become reality - even against overwhelming odds.
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.
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.
By the turn of the millennium, it had become painfully apparent that the United States had made some serious misjudgments in its interactions with the natural world. The country's treasured national parks, while remaining immensely popular tourist destinations, were not immune to the damage. Preservation alone would no longer be enough; by this time, repair and restoration were necessary. Can the United States reverse the mistaken policies that severely damaged the crown jewels of its national park system? This thoughtful and hopeful book, in turns analytical and personal, investigates that critical question by focusing on four of America's most-loved public paces. In "Repairing Paradise," William Lowry, an eminent expert on U.S. natural resource policy, details and assesses four ambitious efforts to reverse environmental damage in the national parks: - The reintroduction of wolves in Yellowstone - Reducing the impact of vehicle traffic in Yosemite - Restoring fresh water to the Everglades - Removing structural impairments to river flows in the Grand Canyon "Repairing Paradise" combines authoritative research with extensive personal experience. Lowry has spent time in all four of the parks --observing conditions, talking to the most informed decisionmakers, and taking photos. He deftly combines his field research with solid public policy analysis to paint an instructive portrait of the mission to restore the natural health and glory of some of the world's most wondrous places.
Butterflies and moths hold an enduring fascination for their unusual life cycle, as they change from one creature into another. Butterflies is an outstanding collection of photographs showcasing nature's most beautiful and often elusive butterflies and moths - members of the Lepidoptera order - in the variety of their natural habitats. With 17,500 species of butterfly and 160,000 species of moth in the world today, they can be found on every continent apart from Antarctica, and in every nation. Arranged in chapters covering some of the most beautiful and interesting types of butterfly and moth, their habitats, their transition from egg to caterpillar and from chrysalid to adult, as well as their behaviour, the book reveals little-known facts about their life cycle, anatomy, self-defence mechanisms, feeding and migration. For example, did you know that while caterpillars chew their solid food, adult butterflies can only consume liquid, and some moths do not even have mouths? Or that many species can taste with their feet? With full captions explaining how the species breeds, feeds, and changes from caterpillar to the animal kingdom's most stunning member, Butterflies is a brilliant examination in more than 200 outstanding colour photographs of these fascinating insects.
The lake charr Salvelinus namaycush is a ubiquitous member of cold-water lake ecosystems in previously glaciated regions of northern continental U.S., Alaska, and Canada that often support important commercial, recreational, and subsistence fisheries. The lake charr differs from other charrs by its large size, longevity, iteroparity, top-predator specialization, reduced sexual dimorphism, prevalence of lacustrine spawning, and use of deepwater habitat. The species is remarkably variable in phenotype, physiology, and life history, some of which is reflected in its ecology and genetics, with as many as four morphs or ecotypes co-occurring in a single lake. The lake charr is often the top predator in these systems, but is highly adaptable trophically, and is frequently planktivorous in small lakes. The lake charr by their name highlights their common habitat, lakes both large and small, but often frequents rivers and occasionally moves into the Arctic Ocean. Movement and behaviour of lake charr are motivated by access to cool, well-oxygenated water, foraging opportunities, predator avoidance, and reproduction. Owing to their broad distribution and trophic level, the lake charr serves as a sentinel of anthropogenic change. This volume will provide an up-to-date summary of what is currently known about lake charr from distribution to genetics to physiology to ecology. The book provides a compilation and synthesis of available information on the lake charr, beginning with an updated distribution and a revised treatment of the paleoecology of the species. Understanding of ecological and genetic diversity and movement and behaviour of the species has advanced remarkably since the last major synthesis on the species over 40 years ago. Mid-sections of the book provide detailed accounts of the biology and life history of the species, and later sections are devoted to threats to conservation and fishery management practices used to ensure sustainability. A new standard lake charr-specific terminology is also presented. The book will be a valuable reference text for biologists around the world, ecologists, and fishery managers, and of interest to the angling public.

Professor Linda M. Fedigan, Member of the Order of Canada and a Fellow of the Royal Society of Canada, has made major contributions to our understanding of the behavioural ecology of primates. Furthermore, Linda Fedigan pioneered and continues to advance scholarship on the role of women in science, as well as actively promoting the inclusion of women in the academy. A symposium in honour of her career was held in Banff (Alberta, Canada) in December 2016, during which former and current students and collaborators, as well as scientists with similar research interests, presented and discussed their work and their connections to Linda Fedigan. These presentations and discussions are here presented as chapters in this festschrift. The original works presented in this book are organized around four major research areas that have been greatly advanced and influenced by Linda Fedigan: Primate life histories Sex roles, gender, and science Primate-environment interactions Primate adaptation to changing environments
