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.
During the century leading up to this book's publication in 1941, there had been a complete revolution in conditions governing the habits and numbers of wildfowl in many parts of the world. Industrial innovations such as the breech-loading gun, the steam-engine, and the internal combustion engine not only increased destruction, but, by disturbance of previously quiet resting places, led to vast changes in distribution. In most locations, these changes were masked by seasonal fluctuations, and too slow for the average wildfowler to notice. But it began to be realised, especially in North America, that the number of wildfowl was seriously diminishing. To obtain accurate information, the International Committee for Bird Preservation adopted a far-reaching scheme of investigation and inquiry. This first volume contains eight papers by specialists.

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.

This book considers a number of problems posed by ungulates and their management in Europe. Through a synthesis of the underlying biology and a comparison of the management techniques adopted in different countries, the book explores which management approaches seem effective and in which circumstances. Experts in a number of different areas of applied wildlife biology review various management problems and alternative solutions, including the impact of large ungulates on agriculture, forestry and conservation habitats, the impact of disease and predation on ungulate populations and the involvement of ungulates in road traffic accidents and possible measures for mitigation. This book is directed at practising wildlife managers, those involved in research to improve methods of wildlife management, and policy-makers in local, regional and national administrations.
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.
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.
This book addresses the multidisciplinary challenges in biodiversity conservation with a focus on wildlife crime and how forensic tools can be applied to protect species and preserve ecosystems. Illustrated by numerous case studies covering different geographical regions and species the book introduces to the fundamentals of biodiversity conflicts, outlines the unique challenges of wildlife crime scenes and reviews latest techniques in environmental forensics, such as DNA metagenomics. In addition, the volume explores the socio-economic perspective of biodiversity protection and provides an overview of national and international conservation laws. The field of conservation medicine stresses the importance of recognizing that human health, animal health, and ecosystem health are inextricably interdependent and the book serves as important contribution towards achieving the UN Sustainable Developmental Goals, in particular SDG 15, Life on Land. The book addresses graduate students, scientists and veterinary professionals working in wildlife research and conservation biology.
This volume is the first scholarly book on the antelope that dominate the savanna ecosystems of eastern and southern Africa. It presents a synthesis of research conducted over a span of fifty years, mainly on the wildebeests in the Ngorongoro and Serengeti ecosystems, where eighty percent of the world's total wildebeest population lives. Wildebeest and other grazing mammals drive the ecology and evolution of the savanna ecosystem. Estes describes this process as well as detailing the wildebeest's life history, focusing on its social organization and unique reproductive system, which are adapted to the animal's epic annual migrations. He also examines conservation issues that affect wildebeest, including range-wide population declines.
Wetlands serve many important functions and provide numerous ecological services such as clean water, wildlife habitat, nutrient reduction, and flood control. Wetland science is a relatively young discipline but is a rapidly growing field due to an enhanced understanding of the importance of wetlands and the numerous laws and policies that have been developed to protect these areas. This growth is demonstrated by the creation and growth of the Society of Wetland Scientists which was formed in 1980 and now has a membership of 3,500 people. It is also illustrated by the existence of 2 journals ("Wetlands" and "Wetlands Ecology and Management") devoted entirely to wetlands. To date there has been no practical, comprehensive techniques book centered on wetlands, and written for wetland researchers, students, and managers. This techniques book aims to fill that gap. It is designed to provide an overview of the various methods that have been used or developed by researchers and practitioners to study, monitor, manage, or create wetlands. Including many methods usually found only in the peer-reviewed or gray literature, this 3-volume set fills a major niche for all professionals dealing with wetlands."
The management of kangaroos is one of the most controversial issues in Australian wildlife management today - kangaroos are 'in plague proportions' or 'on the verge of extinction' depending on whom you spoke to last. This book examines the ecology and management of kangaroos and shows how they interact with their own environment and with that shaped by sheep grazing and the wool industry. It presents the results of intensive and detailed studies of feeding behaviour, movement and habitat utilisation, body condition and population dynamics, weather and plant growth. These are then synthesised to produce a clear picture of how kangaroos cope so successfully with the climatic extremes of the arid zone, how they and the sheep jointly affect each other's fortunes, and what the options are for the future management of kangaroos both within the national parks and on the sheep rangelands.
With up to a quarter of all insect species heading towards
extinction over the next few decades, there is now a pressing need
to summarize the techniques available for measuring insect
diversity in order to develop effective conservation strategies.
Nearly all cultures, from ancient times to today, have used plants as a source of medicine. In many developing countries, traditional medicine is still the mainstay of health care and most of the drugs and cures used come from plants. In developed countries many people are turning to herbal remedies. With this widespread use has come the assumption that plants identified as having medicinal qualities will be available on a continuing basis. However no concerted effort has been made to ensure this and in the face of the threats of increasing demand, a vastly increasing human population and extensive forest destruction, there can be no guarantee that we will continue to benefit indefinitely from this valuable resource. In light of this situation the World Health Organisation held a meeting in 1988. This book is the outcome of that meeting, detailing in a series of papers by leading experts the problems of which need to be addressed, the existing experiences from a range of countries and the future direction which must be taken to ensure the conservation of the world's medicinal plants.
Forests host a disproportionate share of the world s biodiversity. They are increasingly being seen as a refuge for genetic diversity, native species, natural structures, and ecological processes. Yet, intensive forestry threatens their value for biodiversity. The authors present concepts, approaches and case studies illustrating how biodiversity conservation can be integrated into forest management planning. They address ecological patterns and processes taking place at the scale of landscapes, or forest mosaics. This book is intended for students and researchers in conservation biology and natural resource management, as well as forest land managers and policy makers. It presents examples from many forest regions and a variety of organisms. With contributions from researchers that are familiar with forest management and forest managers working in partnership with researchers, this book provides insight and concrete tools to help shape the future of forest landscapes worldwide.
Nutrition spans a wide range of mechanisms from acquisition of food to digestion, absorption and retention of energy substrates, water and other nutrients. Nutritional principles have been applied to improving individual health, athletic performance and longevity of humans and of their companion animals, and to maximizing agricultural efficiency by manipulating reproduction or growth of tissues such as muscle, hair or milk in livestock. Comparative nutrition borrows from these tra- tional approaches by applying similar techniques to studies of ecology and physiology of wildlife. Comparative approaches to nutrition integrate several levels of organization because the acquisition and flow of energy and nutrients connect individuals to populations, populations to communities, and communities to ecosystems. Integrative Wildlife Nutrition connects behavioral, morphological and biochemical traits of animals to the life history of species and thus the dynamics of populations. An integrated approach to nutrition provides a practical framework for understanding the interactions between food resources and wildlife popu- tions and for managing the harvest of abundant species and the conservation of threatened populations. This book is for students and professionals in animal physiology and ecology, conservation biology and wildlife management. It is based on our lectures, dem- strations and practical classes taught in the USA, Canada and Australia over the last three decades. Instructors can use Integrative Wildlife Nutrition as a text in wildlife and conservation biology programs, and as a reference source for related courses in wildlife ecology.
Insects are the most diverse and abundant animals that share our world, and conservation initiatives are increasingly needed and being implemented globally, to safe guard the wealth of individual species. This book provides sufficient background information, illustrated by examples from many parts of the world, to enable more confident and efficient progress towards the conservation of these ecologically indispensable animals. Writing for graduate students, academic researchers and professionals, Tim New describes the major ingredients for insect species management and conservation, and how these may be integrated into effective practical management and recovery plans.
Conservation genetics focuses on understanding the role and
requirement of genetic variation for population persistence.
However, considerable debate now surrounds the role of genetic
factors (as opposed to non-genetic factors such as habitat
destruction etc.) in population extinction, and a comprehensive
synthesis is now timely. Can extinction be explained by habitat
destruction alone or is lack of genetic variation a part of the
explanation? The book thoroughly reviews the arguments for a role
of genetics in the present biodiversity crisis. It describes the
methods used to study genetic variation in endangered species and
examines the influence of genetic variation in the extinction of
species.
`Ireland's heritage is being steadily whittled away by human exploitation, pollution and other aspects of modern development. This could represent a serious loss to the nation.' Irish Government Report, June 1969 Nature in Ireland is disappearing at an alarming rate. Overfishing, industrial-scale farming and pollution have decimated wildlife habitats and populations. In a single lifetime, vast shoals of herring, rivers bursting with salmon, and bogs alive with flocks of curlew and geese have all become folk memories. Coastal and rural communities are struggling to survive; the foundations of our tourism and agricultural sectors are being undermined. The lack of political engagement frequently sees the state in the European Court of Justice for environmental issues. Padraic Fogarty authoritatively charts how this grim failure to manage our natural resources has impoverished our country. But all is not lost: he also reveals possibilities for the future, describing how we can fill our seas with fish, farm in tune with nature, and create forests that benefit both people and wildlife. He makes a persuasive case for the return of long-lost species like wild boar, cranes and wolves, showing how the interests of the country and its nature can be reconciled. A provocative call to arms, Whittled Away presents an alternative path that could lead us all to a brighter future.
The subject matter of this text is conference based and deals with the physiology, ecology and management of orchid conservation. It offers information not only to the orchid research scientist, but also to the orchid enthusiast curious about the scientific background to this topic. Interest and support for plant conservation has increased considerably and a great deal of attention has been focused on the plight of members of the orchid family. The development makes it desirable to collect existing information and to consider areas of research.
Why do Australian rainforests occur as islands within the vast tracts of Eucalyptus? Why is fire a critical ecological factor in every Australian landscape? What were the consequences of the use of fire by the Ice Age colonists? In this original and challenging book, David Bowman critically examines all hypotheses that have been advanced to answer these questions. He demonstrates that fire is the most critical factor in controlling the distribution of rainforest throughout Australia. Furthermore, while Aboriginal people used fire to skillfully manage and preserve habitats, he concludes that they did not significantly influence the evolution of Australia's unique flora and fauna. This volume, the first comprehensive overview of the diverse literature on this topic, solves the puzzle of the archipelago of rainforest habitats in Australia. It is essential reading for all ecologists, foresters, conservation biologists, and others interested in the biogeography and ecology of Australian rainforests.
Mushrooms, the first of a major new series of books on British natural history, provides a remarkable insight into the natural and human world of fungi. Peter Marren, in his inimitable, relaxed style, guides the reader through the extraordinary riches of this often overlooked group, from the amazing diversity of forms and lifestyles that populate the fungal landscape, to the pursuit of edible fungi for the pot, and the complexities of identification thrown up by our modern understanding of DNA. Throughout the book, the author tells a story rich in detail about how we have come to appreciate and, in some cases, fear the mushrooms and toadstools that are such an integral part of the changing seasons. Marren also provides a refreshingly candid view of our attempts to name species, the role of fungi in ecosystems, and our recent efforts to record and conserve them.
Habitat management is commonly used to maintain and enhance the
biological interest of many areas of semi-natural habitat where
natural processes no longer create suitable conditions for desired
species. Habitat restoration and creation is increasingly being
used to increase the extent of ecologically important habitats in
order to mitigate the impacts of human development. The
modification of past management techniques and the introduction of
new ones can provide additional benefits.
Because elephants are pachyderms, a combination of two Greek roots meaning "thick skin," one might think that nothing bothers them and that they lead quiet, safe lives. Nothing could be further from the truth: elephants have been hunted and killed for their ivory tusks since antiquity. And people often ignore the calves left behind, who must now live out their lives as traumatized and fearful orphans. Wildlife photographer Joachim Schmeisser made it his mission to document the story of these abandoned baby elephants. Through his sponsorship of elephants, he came into contact with the David Sheldrick Wildlife Trust, the world's largest and most successful rescue and rehabilitation operation for orphaned elephants, headquartered in Nairobi. Professional veterinary technicians bottle feed the elephant calves until they are old enough to locate their own food. By living together with older elephant calves, they also learn the social rules governing elephant herds. After this phase is complete, the elephants are taken to one of the Trust's rehabilitation stockades before they are released back into the wild. Joachim Schmeisser followed numerous elephants through the entire process and captured fascinating pictures from their arrival at the nursery all the way to their release back into the wild. Elephants in Heaven provides a visual record of how these traumatized elephants are raised in a place that is truly heavenly for them, offering a compelling behind-the-scenes look inside an elephant nursery. The touching animal portraits also convey the devastating consequences of poaching, because for Joachim Schmeisser, it's about "beauty, fragility, tran- sience, mindfulness, and about dignity and the equal standing of each individual." |
