Rethinking Fisheries Governance - The Role of States and Meta-Governance (Paperback, Softcover reprint of the original 1st ed.... Rethinking Fisheries Governance - The Role of States and Meta-Governance (Paperback, Softcover reprint of the original 1st ed. 2018)

This book explores how the state can foster collective action by fisher's communities in fisheries management. It presents a different perspective from Elinor Ostrom's classic work on the eight institutional conditions that foster collective action in natural resource management and instead emphasizes the role of the state in fisheries co-management, engaging a state-centric notion of 'meta-governance'. It argues that first, the state is required to foster collective action by fishers; and secondly, that the current fisheries co-management arrangements are state-centric. The study develops these arguments through the analysis of three case studies in Japan, Vietnam and Norway. The author also makes a theoretical contribution to governance literature by developing Ostrom's 'society-centric' framework in a way which makes it more amenable to the analysis of state capacity and government intervention in a comparative context. This book will appeal to students and scholars of global governance, fisheries management, co-management, and crisis management, as well as practitioners of fisheries management.

R5,864 Discovery Miles 58 640 Ships in 18 - 22 working days

This book provides a snapshot of representative modeling analyses of coastal hypoxia and its effects. Hypoxia refers to conditions in the water column where dissolved oxygen falls below levels that can support most metazoan marine life (i.e., 2 mg O2 l-1). The number of hypoxic zones has been increasing at an exponential rate since the 1960s; there are currently more than 600 documented hypoxic zones in the estuarine and coastal waters worldwide. Hypoxia develops as a synergistic product of many physical and biological factors that affect the balance of dissolved oxygen in seawater, including temperature, solar radiation, wind, freshwater discharge, nutrient supply, and the production and decay of organic matter. A number of modeling approaches have been increasingly used in hypoxia research, along with the more traditional observational and experimental studies. Modeling is necessary because of rapidly changing coastal circulation and stratification patterns that affect hypoxia, the large spatial extent over which hypoxia develops, and limitations on our capabilities to directly measure hypoxia over large spatial and temporal scales. This book consists of 15 chapters that are broadly organized around three main topics: (1) Modeling of the physical controls on hypoxia, (2) Modeling of biogeochemical controls and feedbacks, and, (3) Modeling of the ecological effects of hypoxia. The final chapter is a synthesis chapter that draws generalities from the earlier chapters, highlights strengths and weaknesses of the current state-of-the-art modeling, and offers recommendations on future directions.

*Levison Wood's documentary series on WALKING WITH ELEPHANTS is available to watch now on Channel 4* This book comes at a critical time. Fifty years ago, Africa was home to just over 1.3 million elephants, but by 1990 the number had halved. Meanwhile in the span of a lifetime, the human population has more than doubled. In Levison Wood's The Last Giants, he explores the rapid decline of one of the world's favourite animals. Filled with stories from his own time spent travelling with elephants in Africa, and documenting their migration in his Channel 4 series, Walking With Elephants, the book is a passionate wake-up call for this endangered species we take for granted. The Last Giants was written to inspire us all to act - to learn more and help save the species from permanent extinction.

Humans and Lions - Conflict, Conservation and Coexistence (Paperback): Keith Somerville Humans and Lions - Conflict, Conservation and Coexistence (Paperback)
Keith Somerville
R1,436 Discovery Miles 14 360 Ships in 10 - 15 working days

This book places lion conservation and the relationship between people and lions both in historical context and in the context of the contemporary politics of conservation in Africa. The killing of Cecil the Lion in July 2015 brought such issues to the public's attention. Were lions threatened in the wild and what was the best form of conservation? How best can lions be saved from extinction in the wild in Africa amid rural poverty, precarious livelihoods for local communities and an expanding human population? This book traces man's relationship with lions through history, from hominids, to the Romans, through colonial occupation and independence, to the present day. It concludes with an examination of the current crisis of conservation and the conflict between Western animal welfare concepts and sustainable development, thrown into sharp focus by the killing of Cecil the lion. Through this historical account, Keith Somerville provides a coherent, evidence-based assessment of current human-lion relations, providing context to the present situation. This book will be of interest to students and scholars of environmental and African history, wildlife conservation, environmental management and political ecology, as well as the general reader.

Many endangered species of wild animals are managed in captivity through studbooks. In this book these data-rich resources are mined in innovative, integrated and statistically tested ways to maximise information gain for conservation practice - whether for captive or released/reintroduced or managed wild populations. This book is thus an important tool for all species managers, and for students and researchers in small population biology and wildlife conservation. The book's studbook analyses are grouped in three interrelated sections: natural history, demography and genetics. Statistical tests to determine the significance of results or to compare results between subgroups are undertaken throughout. Real studbooks of a variety of species, e.g. cranes, wolverines, blesbok, illustrate the practical applications and interpretations of the analyses and statistics. The "natural history" section presents analyses to determine baseline species information such as litter size, inter-birth interval, longevity and seasonality. "Demography" covers census(-style) analyses, age-class based life tables, comparative survival analyses and population projections. Solutions for dealing with small sample sizes are included.Inbreeding depression and unconscious selection form the main focus of the "genetics" section. Survival and life table analyses are used to assess inbreeding effects. Quantitative genetics methods are applied to natural history traits as a tool to monitor genetic variation. A fourth section on "conservation" shows how data from captive populations can be used where natural history data from wild populations are missing. A real example uses studbook data to inform Population Viability Analysis. The final section deals with issues related to incomplete and missing data and statistical topics. The purpose-written open-source software programs "Population Management Library (PML)" and "studbookR" used for analyses in the book, are available at www.princee.com.

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.

This Brief discusses potential alternative sources for feeds in aquaculture fish diet, and explains that the future of aquaculture's development is dependent on the costs of fishmeal and fish oil. Considering that the increasing costs of traditional feeds constrain this development, research is looking into alternatives, which can ensure adequate nutrition for animals' growth. This work reviews the use of alternative plant, microbial and insect protein sources, evaluating in particular their impact on growth, nutrient digestibility, fillet quality traits and sensorial perception in the most important farmed marine and freshwater fish species. The Brief specifically summarizes the pros and cons of plant oils from oilseeds, which can on the one hand be a sustainable substitute for fish oil, but which are on the other hand less rich in omega-3 long-chain polyunsaturated fatty acids. The feeding might therefore result in an undesired reduced nutritional value of the flesh of farmed fish. The authors also explore the possible use of fishery discards as potential aquaculture feed source. Since the landing of by-catch will with the new Common Fisheries Policy (CFP) become obligatory (instead of simply returning it to the sea, often dead), suitable uses of what must not be used for human consumption can be investigated. The authors give an outlook whether this might become a sensible alternative to improve the management of discards and create more sustainable fisheries. The Brief also addresses the issues of additives to aquafeeds, such as vitamins, minerals, and antioxidants, but also immunostimulants and enzymes. The authors discuss which effects these additives may have on fish growth, welfare, reproduction and health status in aquacultures.

Art about glaciers, queer relationships, political anxiety, and the meaning of Blackness in open space-Borealis is a shapeshifting logbook of Aisha Sabatini Sloan's experiences moving through the Alaskan outdoors. In Borealis, Aisha Sabatini Sloan observes shorelines, mountains, bald eagles, and Black fellow travelers while feeling menaced by the specter of nature writing. She considers the meaning of open spaces versus enclosed ones and maps out the web of queer relationships that connect her to this quaint Alaskan town. Triangulating the landscapes she moves through with glacial backdrops in the work of Black conceptual artists and writers, Sabatini Sloan complicates tropes of Alaska to suggest that the excitement, exploration, and possibility of myth-making can also be twinned by isolation, anxiety, and boredom. Borealis is the first book commissioned for the Spatial Species series, edited by Youmna Chlala and Ken Chen. The series investigates the ways we activate space through language. In the tradition of Georges Perec's An Attempt at Exhausting a Place in Paris, Spatial Species titles are pocket-sized editions, each keenly focused on place. Instead of tourist spots and public squares, we encounter unmarked, noncanonical spaces: edges, alleyways, diasporic traces. Such intimate journeying requires experiments in language and genre, moving travelogue, fiction, or memoir into something closer to eating, drinking, and dreaming.

Catch and Release - The Enduring Yet Vulnerable Horseshoe Crab (Paperback): Lisa Jean Moore Catch and Release - The Enduring Yet Vulnerable Horseshoe Crab (Paperback)
Lisa Jean Moore
R932 Discovery Miles 9 320 Ships in 18 - 22 working days

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

`Any fool can destroy trees. They cannot run away … God has cared for these trees … but he cannot save them from fools – only Uncle Sam can do that.’ First published in 1901, Our National Parks is possibly the bestselling book of Muir’s wilderness-discovery titles and was certainly the most influential published in his lifetime, with a strong focus on the preservation of forest reserves. With a strong political tone and shrewd, subtle manoeuvring, Muir uses Our National Parks to persuade his readership of the necessity of nature and national parks for human recreation and more importantly for health and wellbeing, as well as the – in his mind – obvious need for preservation of wild ecosystems. Cannily he counterbalances this with the acknowledgement of the need for timber and irrigation systems, in order that his message is taken seriously; Muir’s passion is portrayed so vividly and flamboyantly that without his learned political and scientific reinforcement, he could be misconstrued as purely a radical and eccentric nonconformist. However, the two combined result in an engaging and convincing argument that these landscapes are our `natural home’, and `fountains of life’. As Muir expert Terry Gifford observes in the foreword, `Muir’s tone can shift in this book from seductive persuasion, to charming details of creatures, flora and landscapes, to scientific information, to trail guide, to religious uplift, to a final political speech of startling ferocity.’ John Muir’s strategic yet genuine and beautiful conservationist essays were a first at the time of publication, and are still highly applicable to our attitudes and lifestyles today in the twenty-first century.

'How glorious a greeting the sun gives the mountains! To behold this alone is worth the pains of any excursion a thousand times over.' John Muir is known internationally for his dedication to protecting the environment and for founding The Sierra Club in 1892. His first book, as Muir authority Terry Gifford writes in the foreword, 'became the bible of the fledgling Sierra Club, which is now a major national environmental activists' organisation with branches in every corner of America'. The Mountains of California not only details Muir's visits to the magnificent mountains along the Sierra Nevada Range, which he affectionately calls 'The Range of Light', but also the stunning glaciers, forests and landscapes that he encounters: 'Climbing higher, I saw for the first time the gradual dwarfing of the pines in compliance with climate ... patches of the dwarf vaccinium with its round flowers sprinkled in the grass like purple hail; while in every direction the landscape stretched sublimely away in fresh wildness: a manuscript written by the hand of nature alone.' Throughout the book, Muir's philosophy of nature's ability to soothe and amaze is evident. He heart-warmingly discusses at length how his encounters with animals, such as the Douglas squirrel, cheered him so. This is a truly beautiful read; Muir's writing, embedded with emotion, wit, and at times, humour, will never fail to speak to his reader. The enthusiasm contained within these pages is infectious, and as well as making a powerful read, Muir will inspire you, too, to 'come and see' the innumerable delights that nature can offer: 'The best words only hint at [California's] charms. Come to the mountains and see.'

The Story of my Boyhood and Youth is the affecting memoir of the now internationally renowned John Muir, a Scottish-American boy subject to a most unusual upbringing, his transition into adulthood, and the path that led him to petition for the concept of protected national parks. Born in East Lothian, Scotland in 1838, Muir was raised by a fanatically strict, religious father with his numerous brothers and sisters and loving mother. From an early age, a shy Muir showed fascination with the natural world, and at aged eleven, his father announced the family were to move to an American wilderness in Wisconsin - Muir had a new playground. His adolescence is spent labouring on the family's grassroots farm. Working seventeen-hour days, an exhausted yet inquisitive Muir desperately snatches moments to himself, yearning to explore the environment around him, secretly studying books on topics other than religion, and rising at 1 a.m. to pursue his hobby of inventing intricate time and energy-saving devices - much to his father's disapproval and everyone else's admiration. At age twenty-two, Muir takes it upon himself to apply to university, and does so without financial or moral support from his father. He makes his way to the University of Wisconsin-Madison to study chemistry and botany, and though never graduating with a degree, he is satisfied that he had learned all he wanted to there, before completing the rest of his nature education in 'the university of the wilderness'. The Story of my Boyhood and Youth includes a new foreword by Terry Gifford, and offers insight into the development of Muir's spiritual connection with the natural world, and suggests an explanation for his passion for freedom in the wilderness, a stark contrast to the forced rigidity of his early years.

With Britain's islands holding more than three-quarters of the Earth's stock of heather moorland, it is an extraordinary fact that it stands as one of the world's rarest habitats. A landscape beloved by millions, it's renowned for the tranquillity and solace it provides - however, this tranquillity is an illusion. Britain's moorlands have, in less than a decade, moved from a position of benign consensus to the epicentre of the bitterest conflict within UK conservation. This insightful book sets out to examine and expose the hidden issues surrounding UK moorland conservation, giving a voice to the many people who work and live there and who feel that what they have to say is often ignored, if it's even heard at all. The fate of our uplands is in our hands, and it is important that an alternative narrative, from the perspective of the practitioners who have cared for these places for generations, are considered. It may be that those with power chose to ignore these facts and sweep them away, but at least now they cannot say they didn't know.

'Many a beautiful plant cultivated to deformity, and arranged in strict geometrical beds, the whole pretty affair a laborious failure side by side with divine beauty.' A Thousand-Mile Walk to the Gulf is the second book in John Muir's Wilderness-Discovery series. It is within this work that we are really given strong clues toward Muir's future trailblazing movement for environmental conservation, in such comments as 'The universe would be incomplete without man; but it would also be incomplete without the smallest transmicroscopic creature that dwells beyond our conceitful eyes and knowledge.' Muir's walk from Indiana to Florida was conceived in order to explore and study further the flora and fauna across states. He undertakes this alone, a dangerous choice perhaps so soon after the civil war, as many characters along the way forewarn. Indeed, Muir is threatened by a robber, and we see a new side to the quiet, lowly gentleman we know as he springs into self-defence mode with lightning initiative and remarkable courage. This is not the only facet of Muir's personality that is uncovered throughout this journey. He makes reference to feeling 'dreadfully lonesome and poor', which is intriguing as his circumstances are self-sought: 'Stayed with lots of different people but preferred sleeping outside alone where possible'. He spends a substantial period of time struck down with malaria, which does not come as a surprise; he was covering many miles on an unsustainably meagre diet with thirst often quenched with swamp water or not at all. Join Muir in Kentucky forests, Cumberland mountains, Florida swamps and all the elegantly described trees, plants, creatures and rocks in-between. A Thousand-Mile Walk to the Gulf teaches us as much about Muir himself as it does the ecosystems in the wilderness across those 1,000 miles.

A lyrical celebration of birdsong, and the rekindling of a deep passion for nature. "At this time of year, blackbirds never simply fly: instead, like reluctantly retired officers, they're always 'on manoeuvres', and it's easy to see from their constant agitation that for them every flower bed is a bunker, every shed a redoubt and every hedge-bottom a potential place of ambush" As the world went silent in lockdown, something else happened; for the first time, many of us started becoming more aware of the spring sounds of the birds around us. Birdsong in a Time of Silence is a lyrical, uplifting reflection on these sounds and what they mean to us. From a portrait of the blackbird - most prominent and articulate of the early spring singers - to explorations of how birds sing, the science behind their choice of song and nest-sites, and the varied meanings that people have brought to and taken from birdsong, this book ultimately shows that natural history and human history cannot be separated. It is the story of a collective reawakening brought on by the strangest of springs.

The proposed book focuses on one of the most important issues affecting humankind in this century - Peak Oil or the declining availability of abundant, cheap energy-and its effects on our industrialized economy and wildlife conservation. Energy will be one of the defining issues of the 21st Century directly affecting wildlife conservation wherever energy extraction is a primary economic activity and indirectly through deepening economic recessions. Since cheap, abundant energy has been at the core of our industrial society, and has resulted in the technological advancements we enjoy today, the peak in world oil extraction would potentially have major impacts on civilization unless we prepare well in advance. One potential economic solution covered in the book would be a Steady State Economy with a stable population and per capita consumption, particularly in such industrialized countries as the United States. Furthermore, the lack of cheap, abundant energy directly and indirectly affects conservation efforts by professional societies and federal and state agencies, and NGOs concerned with wildlife issues. We need to recognize these potential problems and prepare, as much as possible, for the consequences stemming from them.

This extensive work focuses on an important group of temperate freshwater fish, approaching the topic from the perspectives of both biology and aquaculture. It compiles the latest research on fish belonging to the Percidae family and describes in detail all biological aspects relevant to the culture of different species, including ecology, reproductive physiology, feeding and nutrition, genetics, immunology, stress physiology and behavior. It also considers commercial fish production and fish farming topics, such as protocols for induction of gonad maturation, spawning, incubation and larval rearing. Expert contributors not only provide a critical peer review of scientific literature but also original research data, and identify effective practical techniques. The book features chapters on systematics, ecology and evolution, on development, metabolism and husbandry of early life stages and on growth, metabolism, behavior and husbandry of juvenile and grow-out stages. Furthermore, the authors consider genetic improvement and domestication, as well as diseases and health management, crucial to the readers' understanding of these fish and how they can be cultured. Both researchers of percid fish biology and aquaculture professionals who are considering intensive and pond culture of percid fishes will value this timely and comprehensive handbook.)

This book provides both the conceptual basis and technological tools that are necessary to identify and solve problems related to biodiversity governance. The authors discuss intriguing evolutionary questions, which involve the sometimes surprising adaptive capacity of certain organisms to dwell in altered and/or changing environments that apparently lost most of their structure and functionality. Space and time heterogeneities are considered in order to understand the patterns of distribution and abundance of species and the various processes that mold them. The book also discusses at which level-from genes to the landscape, including individuals, populations, communities, and ecosystems-men should intervene in nature in order to prevent the loss of biodiversity.

Biological invasions by alien (non-native) species are widely recognized as a significant component of human-caused global environmental change and the second most important cause of biodiversity decline. Alien species threaten many European ecosystems and have serious environmental, economic and health impacts. The DAISIE (Delivering Alien Invasive Species Inventories for Europe) project has now brought together all available information on alien species in Europe (terrestrial, aquatic and marine) and from all taxa (fungi, plants, animals). Thus for the first time, an overview and assessment of biological invasions in the Pan-European region is finally possible. The Handbook of Alien Species in Europe summarises the major findings of this groundbreaking research and addresses the invasion trends, pathways, and both economic as well as ecological impact for eight major taxonomic groups. Approximately 11.000 alien species recorded in Europe are listed, and fact sheets for 100 of the most invasive alien species are included, each with a distribution map and colour illustration.

What have we learnt about the Nile since the mid-1970s, the moment when Julian Rzoska decided that the time had come to publish a comprehensive volume about the biology, and the geological and cultural history of that great river? And what changes have meanwhile occurred in the basin? The human popu- tion has more than doubled, especially in Egypt, but also in East Africa. Locally, industrial development has taken place, and the Aswan High Dam was clearly not the last major infrastructure work that was carried out. More dams have been built, and some water diversions, like the Toshka lakes, have created new expanses of water in the middle of the Sahara desert. What are the effects of all this on the ec- ogy and economy of the Basin? That is what the present book sets out to explore, 33 years after the publi- tion of "The Nile: Biology of an Ancient River". Thirty-seven authors have taken up the challenge, and have written the "new" book. They come from 13 different countries, and 15 among them represent the largest Nilotic states (Egypt, Sudan, Ethiopia, Uganda, and Kenya). Julian Rzoska died in 1984, and most of the - authors of his book have now either disappeared or retired from research. Only Jack Talling and Samir Ghabbour were still available to participate again.
