'When a man plants a tree, he plants himself. Every root is an anchor, over which he rests with grateful interest, and becomes sufficiently calm to feel the joy of living.' Steep Trails encompasses a delightful mix of John Muir's essays and adventure narratives, spanning a period of twenty-nine years. The selections included in this book are varied: ranging from geological studies to stories of the people and towns he encounters throughout his exploits. As Muir expert Terry Gifford observes in the foreword, 'Most of Steep Trails' chapters are dispatches from Muir as travelling correspondent with a mixture of insights into local cultures, criticism of pollution and enthusiasm for everything wild.' Muir's refreshing philosophy of being 'at one' with nature shines through every account he details, as does his agenda for environmental activism - to treat wildness lovingly, rather than selfishly for material greed. Covering mostly the western regions of the states, California, Washington, Nevada, The Grand Canyon, Oregon and Utah; Steep Trails showcases Muir's passion continuously as he climbs mountains, bathes in lakes, and sketches his findings. Muir's classic extended metaphors and knowledgeable tone are present throughout, making for both an enjoyable and educational read. The enthusiasm contained within these pages is infectious, and as well as simply describing the beauty he sees, Muir will inspire you too, to 'go and see for yourselves' the rewards of studying the endless gift of nature: 'Surely faithful and loving skill can go no farther in putting the multitudinous decorated forms on paper. But the colours, the living, rejoicing colours, chanting morning and evening in chorus to heaven! Whose brush or pencil, however lovingly inspired, can give us these? And if paint is of no effect, what hope lies in pen-work? Only this: some may be incited by it to go and see for themselves.'

The world's mediterranean-type climate regions (including areas within the Mediterranean, South Africa, Australia, California, and Chile) have long been of interest to biologists by virtue of their extraordinary biodiversity and the appearance of evolutionary convergence between these disparate regions. These regions contain many rare and endemic species. Their mild climate makes them appealing places to live and visit and this has resulted in numerous threats to the species and communities that occupy them. Threats include a wide range of factors such as habitat loss due to development and agriculture, disturbance, invasive species, and climate change. As a result, they continue to attract far more attention than their limited geographic area might suggest. This book provides a concise but comprehensive introduction to mediterranean-type ecosystems. It is an accessible text which provides an authoritative overview of the topic. As with other books in the Biology of Habitats Series, the emphasis in this book is on the organisms that dominate these regions although their management, conservation, and restoration are also considered.

The chronicle of a family's first year alone in Alaskan wilderness, here is a poetic exploration into what we value in life. In 1992 Jean Aspen took her husband, Tom, and their young son to live in Alaska's interior mountains where they built a cabin from logs, hunted for food, and let the vast beauty of the Arctic close around them. Jean had faced Alaska's wilderness alone before in a life-altering experience she shared in Arctic Daughter. Cut off from the rest of the world for more than a year, now her family would discover strength and beauty in their daily lives. They candidly filmed themselves and later produced a companion documentary, ARCTIC SON: Fulfilling the Dream, which shows on PBS stations across the nation. From an encounter with a grizzly bear at arm's length to a challenging six-hundred-mile river passage back to civilization, Arctic Son chronicles fourteen remarkable months alone in the Brooks Range. At once a portrait of courage, a lyrical odyssey, and authentic adventure, this is a family's extraordinary journey into America's last frontier.

From shark attack survivor to the shark's biggest advocate, Paul de Gelder tells us just why these majestic diverse animals need our help as much as we need them. Something happens to you the first time you dive with sharks... We have a perennial fascination with sharks. Portrayed in the media and popular culture as killing machines, we are awed by their power and strength. But the shark is so much more - a marvel of the sea, they have evolved over 450 million years into over 500 species, from the bioluminescent kitefin to the tiny dwarf lantern shark, the sociable lemon shark to the blue shark, which can birth up to 100 pups in one litter. Bringing balance to the ocean's ecosystem, our planet is at serious risk when these amazing creatures are threatened. Paul de Gelder, who lost two limbs in a shark attack during a mission as an elite Australian navy clearance diver, spent time as part of his recovery learning all about sharks. He became so obsessed that, despite what happened to him, he is now an expert and has dedicated his life to helping save them. Shark is his love-letter to these unfairly vilified animals, and his warning to the world about what will happen if we don't look out for them.

Waking up to roaring lions near her doorless dung hut; encountering elephants while walking with other women to fetch water from a distant spring; realising that older Himba people saw themselves as part of nature, not as separated from it nor at its apex ... These were just some of the experiences that would change the way Margaret Jacobsohn thought about wildlife conservation – and our modern deficiency in ecological intelligence. So, the Capetonian journalist and environmental writer turned researcher became a Namibian and helped pioneer an African way of doing conservation and tourism.

Famed for its spectacular landscapes and gloriously unclad geology, Namibia is a country that wears its skeleton on the outside, the author says.

Similarly, her story is as gritty and real as Namib sand. The conflicts and mishaps, the triumphs and breakthroughs – what it takes to break paradigms and do decades of community based conservation in remote and inaccessible places, earning some of the top international environmental awards along the way.

A book that will make you think.

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.

With its iconic appearance and historic popular appeal, the giraffe is the world's tallest living terrestrial animal and the largest ruminant. Recent years have seen much-needed new research undertaken to improve our understanding of this unique animal. Drawing together the latest research into one resource, this is a detailed exploration of current knowledge on the biology, behaviour and conservation needs of the giraffe. Dagg highlights striking new data, covering topics such as species classification, the role of infrasound in communication, biological responses to external temperature changes and motherly behaviour and grief. The book discusses research into behaviour alongside practical information on captive giraffe, including diet, stereotypical behaviour, ailments and parasites, covering both problems and potential solutions associated with zoo giraffe. With giraffe becoming endangered species in Africa, the book ultimately focuses on efforts to halt population decline and the outlook for conservation measures.

This book focuses on the effects of industrial effluents, specifically those generated from tanneries, on aquatic life i.e. fish. Readers will learn about the impacts of untreated effluents that find its way into potable water bodies, rivers and lakes. A detailed analysis of the morphological and reproductive responses of fish to Chromium VI, a carcinogen and hazardous metal, will be provided. Particular attention is given to the effects of these effluents on the guppy, a fish used for the biological control of malaria. Students and researchers in environmental science, biology, ecology, marine and freshwater sciences will find the book most appealing. Freshwater ecologists working in the field and managers responsible for the protection and monitoring of natural areas will also find this book interesting.

This book sheds new light on the causes and consequences of elephant migration in the Panchet Forest Division of Bankura District in West Bengal, India- an area characterized by fragmented forested landscape modified by agriculture and settlement expansion. Anthropogenic activities result in the decline in quality and coverage of forests, loss of biodiversity and removal of forest corridors which ultimately restrict or modify the movement of elephants causing a forceful change of their habitats. A major objective of this monograph is to identify the characteristics of man-elephant conflicts in terms of land use change, cropping patterns, ecological characteristics of the fragmented dry deciduous forest, trends and patterns of elephant migration, and livelihood patterns of the inhabitants in the affected areas. Readers will discover insights into changes in the behavioral pattern of elephants and local people in the conflict ridden zones, and how this influences food selection. Through this book we also learn about rational management strategies that can be employed on the local and national level to mitigate human-elephant conflicts. Ecologists, landscape conservation planners and environmental managers engaged in the conservation of large vertebrates in fragmenting and human-dominated landscapes will find this book valuable.

This volume examines fish sounds that have a proven signal function, as well as sounds assumed to have evolved for communication purposes. It provides an overview of the mechanisms, evolution and neurobiology behind sound production in fishes, and discusses the role of fish sounds in behavior with a special focus on choice of mate, sex-specific and age-specific signaling. Furthermore, it highlights the ontogenetic development of sound communication and ecoacoustical conditions in fish habitats and the influence of hormones on vocal production and sound detection. Sound Communication in Fishes offers a must-have compendium for lecturers, researchers and students working in the fields of animal communication, fish biology, neurobiology and animal behavior.

This volume is an interdisciplinary mix of perspectives and studies on social issues in fisheries from a diverse range of case studies and research disciplines. The case is made regarding the dearth of attention to socio-cultural considerations which to date have been largely treated as an externality of fisheries policy. It will be valuable to researchers and decision makers interested in understanding the social dimension of fisheries and provides a timely and relevant compilation of research and analysis on some of the critical socio-cultural issues facing fisheries management and fishing communities today.

Deepen your connection to the natural world with this inspiring meditation, "a path to the place where science and spirit meet" (Robin Wall Kimmerer).In Rooted, cutting-edge science supports a truth that poets, artists, mystics, and earth-based cultures across the world have proclaimed over millennia: life on this planet is radically interconnected. Our bodies, thoughts, minds, and spirits are affected by the whole of nature, and they affect this whole in return. In this time of crisis, how can we best live upon our imperiled, beloved earth?Award-winning writer Lyanda Lynn Haupt's highly personal new book is a brilliant invitation to live with the earth in both simple and profound ways-from walking barefoot in the woods and reimagining our relationship with animals and trees, to examining the very language we use to describe and think about nature. She invokes rootedness as a way of being in concert with the wilderness-and wildness-that sustains humans and all of life.In the tradition of Rachel Carson, Elizabeth Kolbert, and Mary Oliver, Haupt writes with urgency and grace, reminding us that at the crossroads of science, nature, and spirit we find true hope. Each chapter provides tools for bringing our unique gifts to the fore and transforming our sense of belonging within the magic and wonder of the natural world.

The book provides the most comprehensive review of lamprey biology since Hardisty and Potter's five-volume "The Biology of Lampreys" published more than 30 years ago.

This first volume offers up-to-date chapters on the systematics, general biology, conservation status, and conservation needs of lampreys. It will serve as an important reference for researchers working on any aspect of lamprey biology and fishery managers whose mandate is to control or conserve lamprey populations.

`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.

This book is a multidisciplinary analysis of cultural, regional and economic factors affecting international food trade. Contributions from expert authors illuminate the importance of food culture prevailing in the market as a basis for decisions about food trading. Central concepts include value chains, conventions and public infrastructure and their importance for international trade. The reader is taken into a discussion about cultural and economic contexts which influence local decisions among buyers and manufacturers of seafood and how those contexts mutually influence trade between countries. Chapters investigate the trading pattern of codfish (Bacalao), between Nordic and Iberian countries and discuss how business relations are created and structured. The driving forces behind such patterns and how business relations become habits which are hard to change, are revealed through the research presented. As a multidisciplinary work, this book will have broad appeal. It will be of interest to those exploring cultural, economic and public policy issues associated with food trade, as well as anyone with an interest in the seafood market or the Nordic and Iberian regions.

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.

This comprehensive book provides a unique overview of advances in the biology and ecology of marine protists. Nowadays marine protistology is a hot spot in science to disclose life phenomena using the latest techniques. Although many protistological textbooks deal with the cytology, genetics, ecology, and pathology of specific organisms, none keeps up with the quick pace of new discoveries on the diversity and dynamics of marine protists in general. The bookMarine Protists: Diversity and Dynamics gives an overview of current research on the phylogeny, cytology, genomics, biology, ecology, fisheries, applied sciences, geology and pathology of marine free-living and symbiotic protists. Poorly known but ecologically important protists such as labyrinthulids and apostome ciliates are also presented in detail. Special attention is paid to complex interactions between marine protists and other organisms including human beings. An understanding of the ecological roles of marine protists is essential for conservation of nature and human welfare. This book will be of great interest not only to scientists and students but also to a larger audience, to give a better understanding of protists' diverse roles in marine ecosystems.

This book offers a timely and comprehensive review of essential research on Peste des Petits Ruminants Virus (PPRV), ranging from its historical distribution, molecular epidemiology, genome structure, viral proteins, immunity, viral pathogenesis, clinical and molecular diagnosis to advances in vaccine developments and future challenges. PPRV, a Rinderpest-like virus, is the causative agent of one of the most rapidly emerging viral diseases among domestic small ruminants, and the host spectrum has now been expanded to wild small ruminants and camels. With the global eradication of the first livestock disease, Rinderpest, attention is now turning to repeating the procedure for PPR. Each of the book's 13 chapters is dedicated to a specific topic, providing up-to-date literature and discussions by renowned scientists who have made seminal contributions in their respective fields of expertise. Special emphasis has been placed on the analysis of different global efforts to eradicate PPR. This book offers a valuable reference source for virologists, field veterinarians, infection and molecular biologists, immunologists, scientists in related fields and veterinary school libraries.

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. The book is complemented by a regularly updated internet database providing free additional information. With its highly interdisciplinary approach, DAISIE and its Handbook will be the basis for future scientific investigations as well as management and control of alien invasive species in Europe.

At the beginning of the 21st century, Antarctica is poised at the edge of a warmer and busier world. Leading Antarctic researchers examine the needs and challenges of Antarctic environmental management today and tomorrow. Through: (i) investigating the impacts of human activities on specific ecosystems and species, (ii) examining existing environmental management and monitoring practices in place in various regions and (iii) interrogating stakeholders, they address the following questions: What future will Business-As-Usual bring to the Antarctic environment? Will a Business-As-Usual future be compatible with the objectives set out under the Antarctic Treaty, especially its Protocol on Environmental Protection? What actions are necessary to bring about alternative futures for the next 50 years? This volume is an outcome of the International Polar Year (2007-2009) Oslo Science Conference (8-12, June, 2010).

This book reports significant progress of scientific research on horseshoe crabs, including aspects of evolution, genetics, ecology, population dynamics, general biology and physiology, within the recent 10 years. It also highlights the emerging issues related to world-wide conservation threats, status and needs. The contributions in this book represent part of an ongoing global effort to increase data and concept sharing to support basic research and advance conservation for horseshoe crabs.

Reproductive biology is more than the development of techniques for helping with too little or too much breeding. While some of the relevant techniques are useful for individual species, technical developments have to be backed up by thorough biological understanding of the background behind the problems. This book is therefore threefold; (1) it provides a snapshot of the state of the art in terms of species-specific reproductive technologies, whether for individual animals or whole taxonomic groups; (2) it sets the reproductive problems in context and emphasizes the links between animal-based problems and the wider world, e.g. reproductive fitness and (3) it looks forward and presents realistic assessments of how effective some of the more recently developed techniques in reproductive technology might be at combating extinctions. This is a wide-ranging book that will be relevant to anyone involved in reproductive biology or in species conservation and provides provide them some useful perspectives about the real utility of current and emerging technologies. It has contributions from experts in reproduction and related fields.

The tropical estuarine systems of Mexico and Central America are an important part of the region´s coastlines; for example Mexico alone possesses more than 770 thousand hectares of mangroves, as well as the largest estuarine mangrove complex on the American Pacific (Marismas Nacionales), yet is one of the poorest studied areas in the world. This is the first book that deals extensively with fisheries management issues in this region from physical-chemistry, ecological and socioeconomic views, providing an understanding on the function and the effects of human activities on these areas, with works undertaken by local scientist.
