Biological diversity is considered one of today's most urgent
environmental concerns, yet the term was first coined only
twenty-five years ago. Why did the concept of biological diversity
so quickly capture public attention and emerge as a banner issue
for the environmental movement? In this book, Timothy J. Farnham
explores for the first time the historical roots of biological
diversity, tracing the evolution of the term as well as the history
of the conservation traditions that contributed to its rapid
acceptance and popularity.
The International Politics of Bird Conservation assesses international cooperation on migratory and endangered birds in different regions of the world. Robert Boardman illustrates that - although birds are protected in international treaties, by national legislation and through the projects of non-governmental organizations - the threats to many species have mounted. Threats arise from ecologically inappropriate agricultural and forestry practices, the spread of cities and the draining of wetlands, among other factors. The author focuses on regional cooperation between governments, NGOs and international organizations. It questions the effectiveness of international cooperation on the protection of birds, particularly migratory and endangered species. The rise of conservation-related scientific research and the historical evolution of bird protection efforts are discussed, as are regional developments in Africa, the Americas, the Arctic, Antarctica, Asia, Australasia, and Europe. The author concludes by identifying emerging trends in environmental governance and suggesting reforms to strengthen these arrangements. This book will prove a fascinating read for researchers, academics, organizations and specialists in a wide range of fields including: bird conservation and wildlife protection, environmental law and policy, global governance, regionalism and transborder cooperation.
In Butterfly Biology Systems Roger Dennis explores key topics and contentious issues in butterfly biology, specifically those in life history and behaviour. Uniquely, using a systems approach, the book focuses on the degree of integration and feedback between components and elements affecting each issue, as well as the links between different issues. The book comprises four sections. The first two sections introduce the reader to principles and approaches for investigating complex relationships, and provide a platform of knowledge on butterfly biology. The final two sections deal in turn with life history and behaviour, covering key issues affecting different stages of development from eggs to adults. The book is extensively illustrated with original diagrams and models, all of which have detailed legends, produced to enhance a broader understanding, and to provide templates for future research. It includes a detailed bibliography and glossary providing an essential gateway to the extensive literature on butterfly biology. Butterfly Biology Systems is essential reading for graduate students and researchers in insect ecology, evolution, behaviour and conservation. It will also be of great value to anyone interested in butterflies. Introduces a systems approach to butterfly biology Includes succinct reviews of the key interrelationships in butterfly life history and behaviour Illustrates more than 100 models to advance research into butterfly biology systems
The first edition of Mike Alexander s "Management Planning for Nature Conservation," brought a new dimension to the modern literature on conservation management. This second edition, a significant enhancement of the original, deals with the development both, conceptual and practical, of adaptive management planning for nature conservation. It is about preparing management plans, and guides the reader through the entire process. Case-studies, including a conservation and access plan, demonstrate the planning process in action. This approach to planning can be applied to any place which is managed entirely, or in part, for wildlife. It can be applied to the management of species or habitats in any circumstance, regardless of site designation. The process is fully compatible with the Convention on Biological Diversity s ecosystem approach to conservation management. Mike Alexander has long been at the forefront of developing management planning for conservation, with experience ranging from Uganda to Estonia, and from Costa Rica to Wales. He is the General Secretary of the Conservation Management System Consortium, a group of organisations with a common aim of raising standards and developing best practice in conservation management and planning. In 2012 Mike Alexander was elected a Fellow of the Society of Biology in recognition of his contribution to nature conservation and in particular management planning. This book has drawn on the experiences and expertise of the CMS consortium and other leaders in both conservation research and wildlife management from around the world. It is essential reading for professional conservation managers and any student studying management planning for conservation within a range of degree and postgraduate courses."
Synthesizes all key aspects of marine governance encompassing institutions, science, law, and policy, ensuring the content is accessible for non-legal experts. This book will be essential reading for students taking marine affairs, science and policy courses. This new edition has been completely revised, updating text in line with recent advances and new chapters added. Pedagogical features for students are also included throughout.
Techniques and theory for processing otoliths from tropical marine fish have developed only recently due to an historic misconception that these organisms could not be aged. Otoliths are the most commonly used structures from which daily, seasonal or annual records of a fish's environmental history are inferred, and are also used as indicators of migration patterns, home range, spatial distribution, stock structure and life history events. A large proportion of projects undertaken on tropical marine organisms involve removal and processing of calcified structures such as otoliths, statoliths or vertebrae to retrieve biological, biochemical or genetic information. Current techniques and principles have evolved rapidly and are under constant modification and these differ among laboratories, and more particularly among species and within life history stages. Tropical fish otoliths: Information for assessment, management and ecology is a comprehensive description of the current status of knowledge about otoliths in the tropics. This book has contributions from leading experts in the field, encompassing a tropical perspective on daily and annual ageing in fish and invertebrates, microchemistry, interpreting otolith microstructure and using it to back-calculate life history events, and includes a treatise on the significance of validating periodicity in otoliths.
Accompanying a major 5-part BBC series presented by David Attenborough and produced by the team behind Planet Earth and Blue Planet, Perfect Planet is an exploration of the unique conditions that make life on earth possible, and how our wildlife is perfectly adapted to its environment. There is no place like home.The conditions of Earth are not just good for life, they are perfect. Everything about our planet - its size, its distance from the Sun, its spin and tilt, its moon - is perfectly suited to our existence, and our planet's forces serve to nurture its spectacular biodiversity. APerfect Planet shows in stunning detail how Earth has always been more than the sum of its parts. Unlike any other astronomical body, it is a living world. Focusing on four key natural forces - global weather systems distributing fresh water to all corners; marine currents delivering nutrients to the deepest reaches of the ocean; solar energy warming and electrifying everything it touches; and volcanic activity fertilising the earth's surface - Huw Cordey reveals to us new levels of this living world, a place populated with astonishing characters living remarkable lives. From Arctic wolves prowling moonlit landscapes or wood frogs, frozen in winter and magically thawing back to life, to flamingos flying thousands of miles to a vast volcanic lake in Africa to breed, we see time and again how animals are perfectly adapted to whatever the environment throws at them. Packed with over 250 full-colour images, and including a foreword by David Attenborough and stills from the BBC series' spectacular footage, APerfect Planet is a stunning exploration of life on Earth - life that is increasingly precious and rare.
A plague is spreading throughout the Florida Everglades. Nonnative Burmese pythons--one of the largest snakes on the planet--are now known to be reproducing freely in the shallow waters of the famed River of Grass. And though scientists work feverishly to learn as much as possible about this unprecedented invader, methods of control remain elusive.
Bears have fascinated people since ancient times. The relationship between bears and humans dates back thousands of years, during which time we have also competed with bears for shelter and food. In modern times, bears have come under pressure through encroachment on their habitats, climate change, and illegal trade in their body parts, including the Asian bear bile market. The IUCN lists six bears as vulnerable or endangered, and even the least concern species, such as the brown bear, are at risk of extirpation in certain countries. The poaching and international trade of these most threatened populations are prohibited, but still ongoing. Covering all bears species worldwide, this beautifully illustrated volume brings together the contributions of 200 international bear experts on the ecology, conservation status, and management of the Ursidae family. It reveals the fascinating long history of interactions between humans and bears and the threats affecting these charismatic species.
In the mid 1970s two events led me to get to know the Yorkshire Dales better than I had previously. Since 1964 I had been to the Malham Tarn Field Centre with groups of students, first from the University of Edinburgh and then from the University of York, and my family very much enjoyed the summer days we spent amid this magnificent hill scenery. In 1976, the British Ecological Society and the National Trust jointly worked on a survey of the biological interest of the National Trust properties of the Kent, East Anglian and Yorkshire Regions. Malham Tarn itself, and the surrounding farms, formed one of the twenty properties of the Yorkshire Region. I spent the bank holiday, that commemorated the Queen's Silver Jubilee, at Malham, looking fairly closely at the National Trust's landholding there. Miss Sarah Priest, who also looked at the National Trust properties, and I produced a report in late 1977, attempting both to describe and to evaluate the nature resources of the National Trust in Yorkshire. In the following year, 1978, the Nature Conservancy Council wanted to survey the whole of the upland area that was known as the Malhaml Arncliffe SSSI (Site of Special Scientific Interest). A contract to look at such an exciting area, considering where boundaries should go, and looking to see if there were important areas of habitat that should be brought within the SSSI, was a superb practical antidote to an office in the University.
Metamorphosis and the transition from larvae or embryos to juveniles in fishes are important in order to answer, for example, questions about: (1) life-history styles and their modifications in evolutionary perspective and within current environmental demands; (2) the development and application of fisheries recruitment models, (3) the use of ontogenetic scales for interspecific comparisons, (4) the identification of ontogenetic shifts in resource use, and (5) the discovery of evolutionary interrelationships of species or genera. This volume is dedicated to recent studies and reviews of existing knowledge on this insufficiently-addressed area of ichthyology. Most of the papers in this volume were presented in Bratislava, Slovakia, at the 1st International Workshop of the Fish Ontogeny Network of Europe (FONE) in September 1997, a meeting sponsored in part by the European Commission. This volume emphasizes an integrated approach to the study of fish ontogeny, which is a process during which one event is related to another and everything is related to everything else, encompassing physiology, morphology, behaviour and niche. Within this comprehensive perspective, the papers in this volume are grouped along four major themes: reflections on early ontogeny and metamorphosis, organism-environment relationships, ontogeny of predator-prey interactions, and behaviour and ontogeny. Among other issues, the papers consider topics such as whether one can identify when fish metamorphosis ends, whether the larva period begins with hatching or with the onset of exogenous feeding, whether fish ontogeny is saltatory' or gradual', and whether larvae are eliminated in some fishes with direct development. The keynote paper of this volume reviews the main topics within contemporary paradigms and the final paper concludes that the onset of the juvenile period can be identified in some species, but precision remains problematic, emphasizing the need for further research in this dynamic area of fish biology.
Fisheries science in North America is changing in response to a changing climate, new technologies, an ecosystem approach to management and new thinking about the processes affecting stock and recruitment. Authors of the 34 chapters review the science in their particular fields and use their experience to develop informed opinions about the future. Everyone associated with fish, fisheries and fisheries management will find material that will stimulate their thinking about the future. Readers will be impressed with the potential for new discoveries, but disturbed by how much needs to be done in fisheries science if we are to sustain North American fisheries in our changing climate. Officials that manage or fund fisheries science will appreciate the urgency for the new information needed for the stewardship of fish populations and their ecosystems. Research organizations may want to keep some extra copies for a future look back into the thoughts of a wide range of fisheries professionals. Fisheries science has been full of surprises with some of the surprises having major economic impacts. It is important to minimize these impacts as the demand for seafood increases and the complexities of fisheries management increase.
Most of the diadromous fish of the world have decreased in distribution and abundance since the beginning of the twentieth century. They are now threatened, and important conservation issues arise. The causes of these trends vary among species and basins but regional human impact (damming, pollution, fisheries) and global change (climate) are suspected to be responsible for these difficulties. This book contains selected papers from an international symposium organised by the Diadfish network held in Bordeaux (France) in 2005. Readers will find up-to-date information on the ecology, ecotoxicology and physiology of several diadromous species (Atlantic salmon, shads, lampreys, eels) and this whole group in Europe. Main impacts are also documented and analysed in case studies, and solutions or remediation actions are presented.
Proper designation of Essential Fish Habitat (EFH) is a highly important spatial measure in any management of fishery resources. EFH is defined as those waters and substrates necessary to fish for spawning, breeding, feeding, or growth to maturity, a definition that includes the physical, chemical and biological properties of marine areas and the associated sediment and biological assemblages that sustain fish populations throughout their full life cycle. This book presents latest advances in EFH mapping and modelling and introduces the environmental approach to EFH identification through the combined use of latest technologies and advanced techniques, such as Remote Sensing, Geographic Information Systems and Spatial Statistics. The contents of this book include overviews and comparisons of different approaches on species habitat modelling, methods to identify teleconnection patterns between large-scale meteo-oceanic phenomena and local environmental variation, and EFH maps for cephalopod, shrimp, hake, anchovy, sardine, and swordfish resources in the Mediterranean. The aims of this book are to provide accumulated knowledge on marine species essential habitat mapping and to be a source for further developments in the important topic of marine resource management.
Skates have become a concern in recent years due to the preponderance of these elasmobranchs that are caught as bycatch or as a directed fishery. This has raised concern because skates have life history characteristics that may make them vulnerable to over-exploitation. It was due to this concern that prompted Drs. David Ebert and James Sulikowski to organize an international symposium on the Biology of Skates . The aims and goals of the symposium were to bring together an international group of researchers to meet, discuss, perhaps develop collaborations, and present their most recent findings. The symposium was held over two days, on 13-14 July, 2006, in conjunction with the 22nd annual meeting of the American Elasmobranch Society in New Orleans, LA. A total of 31 authors from four countries contributed 16 papers that appear in this volume. The papers are broadly arranged into four separate categories: systematics and biogeography, diet and feeding ecology, reproductive biology, and age and growth. This is the first dedicated book on the biology of skates. We hope that readers will find this volume of interest and that it helps encourage and stimulate future research into these fascinating fishes."
Most aquatic ecosystems have variable water levels. These water-level fluctuations (WLF) have multiple effects on the organisms above and below the waterline. Natural WLF patterns in lakes guarantee both productivity and biodiversity, while untimely floods and droughts may have negative effects. Human impacts on WLF have led to a stabilization of the water levels of many lakes by hydraulic regulation, untimely drawdown due to water use, or floods due to water release from hydropower plants in the catchments. This book provides a first review in this field. It presents selected papers on the ecological effects of WLF in lakes, resulting from a workshop at the University of Konstanz in winter 2005. Issues addressed here include the extent of WLF, and analyses of their effects on different groups of biota from microorganisms to vertebrates. Applied issues include recommendations for the hydrological management of regulated lakes to reduce negative impacts, and a conceptual framework is delivered by an extension of the floodpulse concept for lakes. Current impacts on water use, including increasing demands on drinking and irrigation water, hydropower etc., and climate change effects on WLF make this book an essential resource for aquatic ecologists, engineers, and decision-makers dealing with the management of lake ecosystems and their catchments.
The 2nd international tagging and tracking symposium was held in San Sebastian, Spain, in October 2007, seven years after the first symposium was held in Hawaii in 2000 (Sibert and Nielsen 2001). In the intervening seven years, there have been major advances in both the capability and reliability of electronic tags and analytical approaches for geolocation of tagged animals in marine habitats. Advances such as increased data storage capacity, sensor development, and tag miniaturization have allowed researchers to track a much wider array of marine animals, not just large and charismatic species. Importantly, data returned by these tags are now being used in population analyses and movement simulations that can be directly utilized in stock assessments and other management applications. Papers in this volume are divided into three sections, the first describing insights into behavior achieved using acoustic, archival, and novel tags, the second reporting on advances in methods of geolocation, while the final section includes contributions where tag data have been used in management of marine species. Accurate documentation of animal movements and behaviors in critical marine habitats are impossible to obtain with other technologies. The management and conservation of marine species are critical in today's changing ocean environment and as electronic tags become more accurate and functional for a diversity of organisms their application continues to grow, setting new standards in science and technology.
The science of wetlands and our understanding of these complex ecosystems have improved considerably. The emergence of multidisciplinary strategies is providing new opportunities and innovative approaches to address issues such as climate change and coastal protection. This book, with contributions from 19 specialists from academia, government, and industry, provides a trans-disciplinary approach to the understanding wetlands science, drawing together a wide range of expertise. Topics covered include the physical aspects that shape different wetlands around the world, as well as wetlands ecology, regulation, policy, and related social and economic issues. Featuring contributions from some of the world's leading wetlands researchers and practitioners, this book provides an invaluable resource for undergraduate and post-graduate training in all aspects of wetlands management, conservation, and construction. It is also a useful auxiliary text for researchers working across disciplines in fields such as wetlands science, law, landscape architecture, environmental engineering, conservation ecology, and related disciplines.

Wild Otters answers the need for an up-to-date, scientifically-oriented introduction to the Lutra lutra species. Based in part on the author's extensive field observations, the book provides a superb basis for active conservation management of a species faced with an increasingly hostile environment. Topics include social organization and behavior, food and foraging strategies, ecological information on their main prey fish, problems of energetics and thermo-insulation, population structure, mortality and reproduction, and the impact of humans. Packed with illustrations and photographs, Wild Otters is perfect for students and researchers in ecology, conservation, zoology, and animal behavior.
We developed the first edition of this book because we perceived a need for a compilation on study design with application to studies of the ecology, conser- tion, and management of wildlife. We felt that the need for coverage of study design in one source was strong, and although a few books and monographs existed on some of the topics that we covered, no single work attempted to synthesize the many facets of wildlife study design. We decided to develop this second edition because our original goal - synthesis of study design - remains strong, and because we each gathered a substantial body of new material with which we could update and expand each chapter. Several of us also used the first edition as the basis for workshops and graduate teaching, which provided us with many valuable suggestions from readers on how to improve the text. In particular, Morrison received a detailed review from the graduate s- dents in his "Wildlife Study Design" course at Texas A&M University. We also paid heed to the reviews of the first edition that appeared in the literature.
Keith Culver and David Castle Introduction Aquaculture is at the leading edge of a surprisingly polarized debate about the way we produce our food. According to the United Nations Food and Agriculture Organization, aquaculture production has increased 8. 8% per year since 1970, far surpassing productivity gains in terrestrial meat production at 2. 8% in the same period (FAO 2007). Like the 'green revolution' before it, the 'blue revolution' in aquaculture promises rapidly increased productivity through technology-driven - tensi?cation of aquaculture animal and plant production (Costa-Pierce 2002; The Economist 2003). Proponents of further aquaculture development emphasize aq- culture's ancient origins and potential to contribute to global food security d- ing an unprecedented collapse in global ?sheries (World Fish Center; Meyers and Worm 2003; Worm et al. 2006). For them, technology-driven intensi?cation is an - dinary and unremarkable extension of past practice. Opponents counter with images of marine and freshwater environments devastated by intensive aquaculture pr- tices producing unsustainable and unhealthy food products. They view the promised revolutionasascam, nothingmorethanclever marketingbypro?t-hungry ?shfa- ers looking for ways to distract the public from the real harms done by aquaculture. The stark contrast between proponents and opponents of modern aquaculture recalls decades of disputes about intensive terrestrial plant and animal agriculture, disputes whose vigor shows that the debate is about much more than food production (Ruse and Castle 2002).
It is more than a thousand years since the exploitation of the elephant began.
Gary Wobeser's successful book from 1994 has been completely updated and enlarged in a new second edition. An in-depth overview of the available techniques for the investigation and management of disease in free-ranging animals is provided. The subjects are illustrated with examples drawn from around the world, with emphasis on the special requirements involved in working with wild animals. The book draws on the author 's training as a wildlife biologist.
Whales and dolphins are icons for the conservation movement. They are the most conspicuous ambassadors for entire marine ecosystems and possibly even for the biosphere as a whole. Concurrent with our realisation of impending threats to their environment is a growing scientific understanding of the social and cognitive complexity of many of these species. This book brings together experts in the relevant diverse fields of cetacean research, to provide authoritative descriptions of our current knowledge of the complex behaviour and social organization of whales and dolphins. The authors consider this new information in the context of how different human cultures from around the world view cetaceans and their protection, including attitudes to whaling. They show how new information on issues such as cetacean intelligence, culture and the ability to suffer, warrants a significant shift in global perceptions of this group of animals and how these changes might be facilitated to improve conservation and welfare approaches.
Organotin compounds, used as antifouling biocides since 1960, are chemical compounds that act as endocrine disrupters. It is not known how organotin compounds cause hormone disturbance, however, and many questions remain about their effect on aquatic organisms. Studies on organotin compounds have recently evolved, with many new findings reported. Following a worldwide ban on organotin compounds in 2008, alternative compounds will mainly be used, with the potential for coastal areas to become contaminated, causing, among other effects, cholinesterase inhibition in aquatic organisms. Use of alternative compounds must be controlled to avoid such errors. These and other findings are described and concisely summarized in this book, providing a useful reference in countries where alternative biocides are being considered. Included are studies on the effects on marine organisms, making this book an excellent aid to experts in environmental chemistry, to government organizations, and to students. |
