Fisheries resources are an important component of natural resources. It is an important source of high-quality animal protein and food for humans, which provides employment, economic benefits and social welfare for people engaged in fishing activities. It also has played an important role in food safety, economic development, and foreign trade. Fisheries resources economics is an important branch of both applied economics and resource economics. Its research object is fishery resources and its economic problems. The economics of fishery resources is to focus on the relationship between the demand for human economic activities and the supply of fishery resources, as well as between fishery resources and its development. This book expounds the reasons for the economic problems of fishery resources and the theoretical principles for solving them, so as to reveal the objective rules of the allocation of fishery resources in different regions and at different times, to coordinate the relationship between the utilization of fishery resources and economic development, and to realize the sustainable development of fishery economy. This book will also provide learning materials for undergraduates, graduate students and practitioners engaged in fishery resources development and scientific management.
"Tiger Moon" is the powerful, poetic story of the two years Fiona and Mel Sunquist spent studying tigers in Nepal-traveling by elephant, avoiding a rhino attack, and learning to recognize individual tigers by roar. A new afterword tells the story of a promising effort to reconnect fractured Nepalese and Indian tiger habitats by developing an arc of protected areas that allows tigers and their prey to move more freely through the large territories they need to survive.
Atlantic Salmon is a cultural icon throughout its North Atlantic range; it is the focus of probably the World's highest profile recreational fishery and is the basis for one of the World's largest aquaculture industries. Despite this, many wild stocks of salmon are in decline and underpinning this is a dearth of information on the nature and extent of population structuring and adaptive population differentiation, and its implications for species conservation. This important new book will go a long way to rectify this situation by providing a thorough review of the genetics of Atlantic salmon. Sponsored by the European Union and the Atlantic Salmon Trust, this book comprises the work of an international team of scientists, carefully integrated and edited to provide a landmark book of vital interest to all those working with Atlantic salmon.
Large ungulates in tropical forests are among the most threatened taxa of mammals. Excessive hunting, degradation of and encroachments on their natural habitats by humans have contributed to drastic reductions in wild ungulate populations in recent decades. As such, reliable assessments of ungulate-habitat relationships and the spatial dynamics of their populations are urgently needed to provide a scientific basis for conservation efforts. However, such rigorous assessments are methodologically complex and logistically difficult, and consequently many commonly used ungulate population survey methods do not address key problems. As a result of such deficiencies, key parameters related to population distribution, abundance, habitat ecology and management of tropical forest ungulates remain poorly understood. This book addresses this critical knowledge gap by examining how population abundance patterns in five threatened species of large ungulates vary across space in the tropical forests of the Nagarahole-Bandipur reserves in southwestern India. It also explains the development and application of an innovative methodology - spatially explicit line transect sampling - based on an advanced hierarchical modelling under the Bayesian inferential framework, which overcomes common methodological deficiencies in current ungulate surveys. The methods and results presented provide valuable reference material for researchers and professionals involved in studying and managing wild ungulate populations around the globe.
How much do we really know about the species that make up the natural world? In this fascinating book Ken Thompson explains what we do and don't understand about biodiversity. We know that most species remain undiscovered, and that biodiversity is gravely threatened - by overfishing, habitat loss, pollution and climate change. Life on Earth has previously experienced five episodes of mass extinction, and we are now in the middle of a sixth. Do We Need Pandas? surveys the Earth's biodiversity, its origins and some of the threats it currently faces. It then asks how biodiversity loss will affect the human race. Will we even notice, and if we do, what will we notice? It asks what we should be doing to secure the survival not only of the species with which we share the planet, but of ourselves - and whether we need to be more concerned about ecosystems as a whole than about iconic species.
Coral reefs are an important tourism resource for many coastal and island destinations and generate a range of benefits to their local communities, including as a food source, income from tourism, employment and recreational opportunities. However, coral reefs are under increasing threat from climate change and related impacts such as coral bleaching and ocean acidification. Other anthropogenic stresses include over-fishing, anchor damage, coastal development, agricultural run-off, sedimentation and coral mining. This book adopts a multidisciplinary approach to review these issues as they relate to the sustainable management of coral reef tourism destinations. It incorporates coral reef science, management, conservation and tourism perspectives and takes a global perspective of coral reef tourism issues covering many of the world's most significant coral reef destinations. These include the Great Barrier Reef and Ningaloo Reef in Australia, the Red Sea, Pacific Islands, South East Asia, the Maldives, the Caribbean islands, Florida Keys and Brazil. Specific issues addressed include climate change, pollution threats, fishing, island tourism, scuba diving, marine wildlife, governance, sustainability, conservation and community resilience. The book also issues a call for more thoughtful development of coral reef experiences where the ecological needs of coral reefs are placed ahead of the economic desires of the tourism industry.
Life histories can be defined as the means by which individuals (or more precisely genotypes) vary their age- or stage-specific expenditures of reproductive effort in response to genetic, phenotypic, and environmental correlates of survival and fecundity. Life histories reflect the expression of traits most closely related to individual fitness, such as age and size at maturity, number and size of offspring, and the timing of the expression of those traits throughout an individual's life. In addition to addressing questions of fundamental importance to ecology and evolution, life-history research plays an integral role in species conservation and management. This accessible primer encompasses the basic concepts, theories, and applied elements of life history evolution, including patterns of trait variability, underlying mechanisms of plastic/evolutionary change, and the practical utility of life-history traits as metrics of species/population recovery, sustainable exploitation, and risk of extinction. Empirical examples are drawn from the entire spectrum of life. A Primer of Life Histories is designed for readers from a broad range of academic backgrounds and experience including graduate students and researchers of ecology and evolutionary biology. It will also be useful to a more applied audience of academic/government researchers in fields such as wildlife biology, conservation biology, fisheries science, and the environmental sciences.

This book presents the latest scientific views on resource use conflicts in the Arctic seas. The main areas of focus are the biological resources of Arctic seas vs. exploitation of oil and gas resources, and the conflicts in between. In addition, climate change is presented as a stressor, which both limits and facilitates the economic availability of resources in the Arctic. The book is divided into five parts. Part 1 examines Arctic ecosystems, resilience of the marine environment and possible conflicts between industrial sector and biological world. The focus of Part 2 is on transport infrastructure along the northern routes. Issues such as Arctic maritime operations, black carbon and unmanned aerial vehicles are considered. Part 3 focuses on resource use conflicts in Arctic seas and on the most recent threats in terms of Arctic oil and gas exploration, offshore logistics operations as well as transportation of oil and oil products. Discussions in Part 4 of the book are concentrated around social aspects and involvement of local communities. Tourism development, preservation of indigenous culture, engagement of communities on relevant Arctic issues, search and rescue in the cold marine environment are examples of questions raised. The book reviews Arctic-specific petroleum regulations, the state of preparedness to oil spill accidents in the region as well as the latest developments in oil spill response technologies and their limitations. Search and rescue operations are reviewed and how working in this harsh Arctic environment affects the ability of rescue technicians to perform the required technical skills. Part 5 considers the sustainability challenges arising from the marine resource exploitation. The focus is on the vulnerability of Arctic ecosystems to disturbance - both natural and anthropogenic.
Nearshore hardbottom reefs of Florida's east coast are used by over 1100 species of fishes, invertebrates, algae, and sea turtles. These rocky reefs support reproduction, settlement, and habitat use, and are energy sources and sinks. They are also buried by beach renourishment projects in which artificial reefs are used for mitigation. This comprehensive book is for research scientists and agency personnel, yet accessible to interested laypersons including beachfront residents and water-users. An unprecedented collection of research information and often stunning color photographs are assembled including over 1250 technical citations and 127 figures. These shallow reefs are part of a mosaic of coastal shelf habitats including estuarine seagrasses and mangroves, and offshore coral reefs. These hardbottom habitats are federally designated as Essential Fish Habitats - Habitats of Particular Concern and are important feeding areas for federally-protected sea turtles. Organismal and assemblage responses to natural and man-made disturbances, including climate change, are examined in the context of new research and management opportunities for east Florida's islands in the sand.
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."
Rewilding is the first popular book on the ground-breaking science behind the restoration of wild nature. As ecologists Paul Jepson and Cain Blythe show, rewilding is a new and progressive approach to conservation, blending radical scientific insights with practical innovations to revive ecological processes, benefiting people as well as nature. Its goal is to restore lost interactions between animals, plants and natural disturbance that are the essence of thriving ecosystems. With its sense of hope and purpose, rewilding is breathing new life into the conservation movement, and enabling a growing number of people - even urban-dwellers - to enjoy thrilling wildlife experiences previously accessible only in remote wilderness reserves. 'De-domesticated' horses galloping across a Dutch 'Serengeti'; beavers creating wetlands in the British countryside; giant tortoises restoring the wildlife of the Mauritian islands; perhaps one day even rhinos roaming the Australian outback - rewilding is full of exciting and inspirational possibilities.
Once described by the actress, Joanna Lumley, as "the man with no fear", Tristan Voorspuy spent his whole life living up to the legend. Early stints in Northern Ireland and Germany with the Blues and Royals regiment were but a precursor to a life defined by his love of Africa, a life cut tragically short in 2017 on his beloved game reserve, Sosian. From his epic motorbike ride from Cairo to Cape Town, to extraordinary wildlife encounters and many death-defying light aircraft near misses, Life on the Edge paints a picture of a man determined to live life to the full. It is also the story of compassion, conservation and, ultimately, tragedy. In the last two decades of his life, Voorspuy transformed the overgrazed and drought-blighted Sosian ranch in Northern Kenya into a celebrated game reserve, acclaimed tourist destination and successful cattle ranch. True to form, it was whilst defending this property that an unarmed Tristan, on horseback, was gunned down and killed, a murder that sent shockwaves around the world.
It is more than a thousand years since the exploitation of the elephant began.
Australia's varied grasslands have suffered massive losses and changes since European settlement, and those changes continue under increasingly intensive human pressures for development and agricultural production. The values of native grasslands for conservation of endemic native biodiversity, both flora and fauna, have led to strong interests in the protection of remaining fragments, especially near urban centres, and documentation of the insects and other inhabitants of grasslands spanning tropical to cool temperate parts of the country. Attention to conservation of grassland insects in Australia is relatively recent, but it is increasingly apparent that grasslands harbour many localised and ecologically specialised endemic species. Their conservation necessarily advances from very incomplete documentation, and draws heavily on lessons from the far better-documented grasslands elsewhere, most notably in the northern hemisphere, and undertaken over far longer periods. From those cases, and the extensive background to grassland management to harmonise conservation with production and amenity values through honing use of processes such as grazing, mowing and fire, the needs and priorities for Australia can become clearer, together with needs for grassland restoration at a variety of scales. This book is a broad overview of conservation needs of grassland insects in Australia, drawing on the background provided elsewhere in the world on the responses to disturbances, and the ecological importance, of some key insect groups (notably Orthoptera, Hemiptera and Lepidoptera) to suggest how insect conservation in native, pastoral and urban grasslands may be advanced. The substantial references given for each chapter facilitate entry for non-entomologist grassland managers and stewards to appreciate the diversity and importance of Australia's grassland insects, their vulnerabilities to changes, and the possibilities for conserving them and the wider ecological roles in which they participate.
Domestic and wild large mammalian herbivores occur on every continent except Antarctica. Through their browsing and grazing, they affect the structure and distribution not only of vegetation, but also of associated fauna. Consequently, the interactions between management practices and herbivore populations influence the biodiversity, structure and dynamics of ecosystems across vast expanses around the globe: signs of human activity that will be detectable for epochs to come. As a follow-up work to The Ecology of Browsing and Grazing, published in 2008, this new volume presents cutting-edge research on the behaviour, distribution, movement, and direct and indirect impacts of domestic and wild herbivores on terrestrial ecosystems. The respective chapters highlight strategic and applied research on cross-cutting issues in palaeontology and ecology, and provide concrete recommendations on the management of large herbivores to integrate production and conservation in terrestrial systems. Given its scope, the book will appeal to students, researchers and anyone interested in understanding these fascinating wild animals and how they shape the natural world.
'Divine beauty all. Here I could stay tethered forever with just bread and water, nor would I be lonely.' In the summer of 1869, John Muir joined a group of shepherds in the foothills of California's Sierra Nevada mountains, that he might study and expand his knowledge of the plants, animals and rocks he found there. My First Summer in the Sierra - first published in 1911 - is the detailed and colourful diary he kept while tending sheep and exploring the wilderness. Muir's account tracks his experiences in the Yosemite Valley and the High Sierra alongside faithful companion Carlo the St Bernard, describing the majestic landscapes and the flora and fauna of the area with the excitement and wonder of a child. From sleeping on silver-fir-bough mattresses to goading wild bears, and valuing everything from tiny pebbles to giant sequoia, he truly immerses himself and falls in love with the wilderness. Muir's enthusiasm is infectious, and over 100 years on his environmental message is more pertinent than ever. With a new introduction from Muir authority Terry Gifford, My First Summer in the Sierra is an enchanting and informative read for anyone passionate about the natural world and its splendours.
Population genomics has provided unprecedented opportunities to unravel the mysteries of marine organisms in the oceans' depths. The world's oceans, which make up 70% of our planet, encompass diverse habitats and host numerous unexplored populations and species. Population genomics studies of marine organisms are rapidly emerging and have the potential to transform our understanding of marine populations, species, and ecosystems, providing insights into how these organisms are evolving and how they respond to different stimuli and environments. This knowledge is critical for understanding the fundamental aspects of marine life, how marine organisms will respond to environmental changes, and how we can better protect and preserve marine biodiversity and resources. This book brings together leading experts in the field to address critical aspects of fundamental and applied research in marine species and share their research and insights crucial for understanding marine ecosystem diversity and function. It also discusses the challenges, opportunities and future perspectives of marine population genomics.
The chimpanzee is one of our planet's best-loved and most instantly recognisable animals. Splitting from the human lineage between four and six million years ago, it is (along with its cousin, the bonobo) our closest living relative, sharing around 94% of our DNA. First encountered by Westerners in the seventeenth century, virtually nothing was known about chimpanzees in their natural environment until 1960, when Jane Goodall travelled to Gombe to live and work with them. Accessibly written, yet fully referenced and uncompromising in its accuracy and comprehensiveness, this book encapsulates everything we currently know about chimpanzees: from their discovery and why we study them, to their anatomy, physiology, genetics and culture. The text is beautifully illustrated and infused with examples and anecdotes drawn from the author's thirty years of primate observation, making this a perfect resource for students of biological anthropology and primatology as well as non-specialists interested in chimpanzees.
This second edition emphasizes the environmental impact on reproduction, with updated chapters throughout as well as complete new chapters on species such as sharks and rays. This is a wide-ranging book that will be of relevance to anyone involved in species conservation, and provides critical perspectives on the real utility of current and emerging reproductive sciences.Understanding reproductive biology is centrally important to the way many of the world's conservation problems should be tackled. Currently the extinction problem is huge, with up to 30% of the world's fauna being expected to disappear in the next 50 years. Nevertheless, it has been estimated that the global population of animals in zoos encompasses 12,000 - 15,000 species, and we anticipate that every effort will be made to preserve these species for as long as possible, minimizing inbreeding effects and providing the best welfare standards available. Even if the reproductive biology community cannot solve the global biodiversity crisis for all wild species, we should do our best to maintain important captive populations. Reproductive biology in this context is much 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 that society might target for a variety of reasons, whether nationalistic, cultural or practical, technical developments have to be backed up by thorough biological understanding of the background behind the problems.
This book sheds light on the major functions of microbial communities in aquaculture ecosystems, showing that by recycling nutrients, degrading organic matter and preventing disease outbreaks, a variety of microbes are truly beneficial to a wide range of aquaculture industries. It discusses how deteriorating environmental quality enables some microbial strains to trigger disease, describes the development of highly sustainable tools to improve water quality, and identifies crucial factors that endanger microbial homeostasis in aquaculture ecosystems. The book also covers post-antibiotic approaches for preventing and treating opportunistic microbial infections based on harnessing environmental and fish-associated microbial communities. Furthermore, it explores how manipulating and engineering these complex microbial communities using bio-agents such as probiotics, phages, natural nutritional additives, or with fine-tuned biofilters will open the door for new ways to develop a more sustainable and cost-effective aquaculture industry. Including an accessible presentation of modern high-throughput sequencing technology to identify host-microbial interactions in aquaculture ecosystems, this book is a valuable resource for scientists, aquaculture and fishery experts, sustainability enthusiasts and scholars in the areas of biology and marine agriculture.
Since the first edition of this book published in 2005, there has been an immense amount of new and fascinating work on the history, ecology, and evolution of the Mediterranean flora. During this time, human impacts have continued to increase dramatically, significantly influencing both the ecology and evolution of the region's biota. This timely and comprehensive update of the original text integrates a diverse and scattered literature to produce a synthetic account of Mediterranean plant evolutionary ecology. It maintains the accessible style of its previous version whilst incorporating recent work in a new structural framework. This is not a traditional "plant science" book per se, but a novel integration of history, ecology, biogeography, and evolution, all set in the context of a dramatically increasing human footprint. There is a particular emphasis on the role of human activities as an ecological factor and their subsequent impact on plant evolution. Conversely, it demonstrates how an understanding of the evolutionary ecology of the region's flora can be used to provide insights into its future conservation and management. Plant Evolution in the Mediterranean is aimed at all those who are interested in the biology of the Mediterranean region, whether it is taxonomy, ecology, evolution, conservation policy and management, or the regional history of its biodiversity in general. It will be of relevance and use to all graduate students and researchers of Mediterranean-type ecosystem ecology and geography, as well as professional ecologists, evolutionary biologists, conservation biologists, and environmental practitioners requiring a concise, authoritative overview of the topic.
Explore the animal kingdom with this pictorial atlas of the world's wildlife. Where do animals build their homes? How do they survive in very hot and cold climates? Why are so many species endangered? Discover the answers to all these questions and many more in The Animal Atlas. This lavishly illustrated nature book takes children on a tour, continent by continent, to meet the animals of the world. Within each section, the book travels through different biomes, such as forests, deserts, and lakes; and specific regions, from the Everglades to the Galapagos, Himalayas, and Great Barrier Reef. The Animal Atlas is packed with beautiful, life-like illustrations of mammals, birds, reptiles, amphibians, and insects that live all around the world, from the Amazon to Antarctica. Each species is carefully hand-drawn to show details of fur, feathers, or scales, while accompanying captions reveal fascinating facts about the animal's behaviour. Maps, along with icons to represent each animal, show precisely where the animals are found. For example, Australia's iconic koala can be tracked down to the east coast of the country. The book starts with an introduction to animal groups and habitats, and finishes with endangered species and a gallery of amazing, record-breaking animals. First published in 1992, this atlas has been updated for the 2020 edition and is a beautiful gift for a new generation of zoologists.
Biostatistics with R provides a straightforward introduction on how to analyse data from the wide field of biological research, including nature protection and global change monitoring.
