R4,515 Discovery Miles 45 150 Ships in 10 - 15 working days

Comparative Evaluations of Innovative Fisheries Management begins with a look at four places outside the European Union known for innovative management: New Zealand, Nova Scotia, Alaska and Iceland. Then the focus shifts to the success criteria related to specific disciplines including biological and social robustness, economic efficiency and impacts on management costs. Hypotheses are tested using data capable of generating useful results. The main conclusions include a retrospective of how key concepts defined and represented the various perspectives, skills and backgrounds that made up the multidisciplinary CEVIS project.

Her first night in a Tanzanian tent began with a prowling lion’s roar. Will the savage terrors open her eyes to an unseen world?

Sue Tidwell lived in awe of Africa’s extraordinary wildlife. After years spent appreciating the animals in her imagination, the tenderhearted American hated the idea of joining her husband on a big game hunt. And getting attacked by blood-sucking tsetse flies the moment she stepped off the plane gave no hint of the mind-blowing change of perspective in her future…

With her initial animosity turning into curiosity as they breathlessly tracked dangerous beasts, Sue formed a surprising bond with their young, government-assigned game scout. And as she became entranced by the tales and wisdom from the Masimba Camp crew, she was humbled by the mystery of the vilified safari and the people who relied on it for survival.

Supplementing her own experiences on the elephant-rutted roads with local insights and scientific research into conservation efforts, Tidwell explores how her preconceived beliefs sluiced away under the deluge of reality. And with an evocative narrative peppered with self-deprecating humor, vivid imagery, and over ninety photos and illustrations, you’ll emerge forever changed by the truths this greenhorn found buried in a rugged and romantic landscape.

Carol A. Johnston
R5,686 Discovery Miles 56 860 Ships in 12 - 19 working days

Bridging the fields of ecosystem science and landscape ecology, this book integrates Dr. Carol Johnston's research on beaver ecosystem alteration at Voyageurs National Park. The findings about the vegetation, soils, and chemistry of beaver impoundments synthesized in the text provide a cohesive reference useful to wetland scientists, ecosystems and landscape ecologysts, wildlife managers, and students. The beaver, Castor canadensis, is an ecosystem engineer unequaled in its capacity to alter landscapes through browsing and dam building, whose population recovery has re-established environmental conditions that probably existed for millenia prior to its near extirpation by trapping in the 1800s and 1900s. Beavers continue to regain much of their natural range throughout North America, changing stream and forest ecosystems in ways that may be lauded or vilified. Interest in beavers by ecologists remains keen as new evidence emerges about the ecological, hydrological, and biogeochemical effects of beaver browsing and construction. There is a critical need for ecologists and land managers to understand the potential magnitude, persistence, and ecosystem services of beaver landscape transformation. The 88-year record of beaver landscape occupation and alteration documented by Dr. Carol Johnston and colleagues from aerial photography and field work provides a unique resource toward understanding the ecosystem effects and sustainability of beaver activity.

Besides the erroneous assumption that tropical fisheries are open access, the cases demonstrate that pre-existing systems (1) are concerned with the community of fishers and ensuring community harmony and continuity; (2) involve flexible, multiple and overlapping rights adapted to changing needs and circumstances; (3) that fisheries are just one component of a community resource assemblage and depend on both the good management of linked upstream ecosystems and risk management to ensure balanced nutritional resources of the community; and (4) pre-existing systems are greatly affected by a constellation of interacting external pressures.

This is the first ever monumental and scientific documentation of the faunal wealth of the Indian Desert state of Rajasthan, covering the species diversity, distribution and conservation status. A scholarly contribution to the field of knowledge, it provides novel and vital information on the vertebrate faunal heritage of India s largest state.

Broadly falling under the Indo-Malaya Ecozone, the three major biomes of Rajasthan include Deserts and Xeric Shrublands; Tropical and Sub-tropical Dry Broadleaf Forests and Tropical and Sub-tropical Moist Broadleaf Forests and the ecoregions thus covered are North Western Thorn Scrub Forests and the Thar Desert; Khathiar-Gir Dry Deciduous Forests and the Upper Gangtic Plains Moist Deciduous Forests, respectively. Contrary to popular belief, the well known Thar or Great Indian Desert occupies only a part of the state. Rajasthan is diagonally divided by the Aravalli mountain ranges into arid and semi-arid regions. The later has a spectacular variety of highly diversified and unique yet fragile ecosystems comprising lush green fields, marshes, grasslands, rocky patches and hilly terrains, dense forests, the southern plateau, fresh water wetlands and salt lakes.

Apart from the floral richness, there is faunal abundance from fishes to mammals. The flagship and threatened species of Tiger; Leopard; Great Indian Bustard and Lesser Florican; White-Napped Tit; Raptors; Demoiselle and Sarus Crane; Chelones; Bats; Wild Ungulates; Small Cats; Bear; Wolf; Wild Dog; Otter; Uromastyx; Giant Flying Squirrel, Gharial and Gangetic Dolphin have been described in the 45 chapters penned by top notch wildlife experts and academics. Chapters covering fossil records; conservation of biodiversity via the age old Public Science of the Desert; Anthropological Account of Communities and Tribes; socio-cultural, mythological and historical aspects of faunal conservation and the fauna in retrospect; wildlife trade; ecotourism; climate and other environmental factors like Indira Gandhi Nahar Pariyojna (IGNP) believed to have changed the ecological face of Western Rajasthan; Protected Area Network; the tiger re-introduction experiment; and community conservation are key attractions. The world famous heronry, tiger reserves, wildlife sanctuaries and some threat-ridden biodiversity rich areas shall certainly draw the attention of readers from around the world.

The last chapter highlighting issues and insights on conservation and management and initiatives and gaps in research will help researchers from India and abroad to identify potential areas of future collaborative work. The strategies suggested herein can be a powerful tool for international conservational advocacy. Supported by rare photographs and paintings, the extensive content has implications for faunal ecology in similar habitats elsewhere on the Earth.

Fish and shellfish comprise annually nearly 70-million tons of the world's edible animal protein. However, because of this demand, previously vast stocks have often been exhausted to the point of near extinction. The first book of its kind in the area of freshwater/marine biodiversity, this extensive work reviews the present status of genetic resource management, its needs and constraints, various intervening human factors such as pollution and overfishing, and problems posed by different species and life-styles. This discussion of the conservation of fish and shellfish resources is illustrated by four diverse groups: Atlantic salmon, cupped oysters, common and Chinese carp, and Nile tilapia. These results, produced by the collaboration of nine leading population and production geneticists, aquaculturists, and behavioral and developmental ecologists should become a fundamental resource useful to biologists, scientists and advisors exploring current issues in the fishery sciences.

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.

Regional intercomparisons between ecosystems on different continents can be a powerful tool to better understand the ways in which ecosystems respond to global change. Large areas are often needed to characterize the causal mechanisms governing interactions between ecozones and their environments. Factors such as weather and climate patterns, land-ocean and land-atmosphere interactions all play important roles. As a result of the strong physical north-south symmetry between the western coasts of North and South America, the similarities in climate, coastal oceanography and physiography between these two regions have been extensively documented. High Latitude Rain Forests and Associated Ecosystems of the West Coast of the Americas presents current research on West Coast forest and river ecology, and compares ecosystems of the Pacific Northwest with those of South America.

This book presents the results from the Japanese Fisheries Research Agency's 3-year intensive monitoring of radionuclides in a variety of fish, plankton, benthos, and their living environments after the Fukushima Daiichi Nuclear Power Plant (FNPP) accident in March 2011. The book reveals the dynamics of contamination processes in marine and freshwater fish, mediated by the contamination of water, sediments, and food organisms; it also clarifies the mechanisms by which large variations in the level of contamination occurs among individual fish. Most importantly, the book includes a large amount of original measurement data collected in situ and for the first time assesses diffusion of radiocesium across the Pacific using both in situ data and a numerical simulation model. Also introduced are several new approaches to evaluate the impact of the release of radionuclides, including the measurement of radiation emission from an otolith section to identify the main period of contamination in fish. The FNPP accident represents a rare instance where the environmental radioactivity level was elevated steeply through atmospheric fallout and direct discharge of radioactive water into the sea over a short period of time. Replete with precise scientific data, this book will serve as an important resource for research in fields such as fishery science, oceanography, ecology, and environmentology, and also as a solid basis for protecting fisheries from damage resulting from harmful rumors among the general public.

'Somehow, the elephants got into my soul, and it became my life's work to see them safe and happy. There was no giving up on that vision, no matter how hard the road was at times.' Francoise Malby-Anthony is the owner of a game reserve in South Africa with a remarkable family of elephants whose adventures have touched hearts around the world. The herd's feisty matriarch Frankie knows who's in charge at Thula Thula, and it's not Francoise. But when Frankie becomes ill, and the authorities threaten to remove or cull some of the herd if the reserve doesn't expand, Francoise is in a race against time to save her beloved elephants . . . The joys and challenges of a life dedicated to conservation are vividly described in The Elephants of Thula Thula. The search is on to get a girlfriend for orphaned rhino Thabo - and then, as his behaviour becomes increasingly boisterous, a big brother to teach him manners. Francoise realizes a dream with the arrival of Savannah the cheetah - an endangered species not seen in the area since the 1940s - and finds herself rescuing meerkats kept as pets. But will Thula Thula survive the pandemic, an invasion from poachers and the threat from a mining company wanting access to its land? As Francoise faces her toughest years yet, she realizes once again that with their wisdom, resilience and communal bonds, the elephants have much to teach us. 'Enthralling' - Daily Mail

In this book, we document and evaluate the recovery of gray wolves (Canis lupus) in the Great Lakes region of the United States. The Great Lakes region is unique in that it was the only portion of the lower 48 states where wolves were never c- pletely extirpated. This region also contains the area where many of the first m- ern concepts of wolf conservation and research where developed. Early proponents of wolf conservation such as Aldo Leopold, Sigurd Olson, and Durward Allen lived and worked in the region. The longest ongoing research on wolf-prey relations (see Vucetich and Peterson, Chap. 3) and the first use of radio telemetry for studying wolves (see Mech, Chap. 2) occurred in the Great Lakes region. The Great Lakes region is the first place in the United States where "Endangered" wolf populations recovered. All three states (Minnesota, Wisconsin, and Michigan) developed ecologically and socially sound wolf conservation plans, and the federal government delisted the population of wolves in these states from the United States list of endangered and threatened species on March 12, 2007 (see Refsnider, Chap. 21). Wolf management reverted to the individual states at that time. Although this delisting has since been challenged, we believe that biological recovery of wolves has occurred and anticipate the delisting will be restored. This will be the first case of wolf conservation reverting from the federal government to the state conser- tion agencies in the United States.

This book reveals how a privatization of fish resources has paved the way for a wide-reaching concentration and change in ownership. It is a thought-provoking contribution to the debate on the future of European fisheries and the possible solutions to overfishing in Europe. Readers will discover a timely, critical insight into the social, cultural and economic aspects and consequences of market-based fisheries management. The privatization of fish quotas in Denmark represents one of the most far-reaching and comprehensive privatization schemes of its kind and has been widely promoted as a market-based system with innovative social safeguards. This work critically examines this privatization of fish resources, combining quantitative and qualitative material to provide new understanding of fish quotas and their social value. Scholars with an interest in privatization and the socio-economic aspects of fisheries, and those working with NGOs, fishers and fisheries, and concerned with political conflicts will all value the research presented here.

Tim R. New
R2,903 Discovery Miles 29 030 Ships in 10 - 15 working days

Losses of forests and their insect inhabitants are a major global conservation concern, spanning tropical and temperate forest regions throughout the world. This broad overview of Australian forest insect conservation draws on studies from many places to demonstrate the diversity and vulnerability of forest insects and how their conservation may be pursued through combinations of increased understanding, forest protection and silvicultural management in both natural and plantation forests. The relatively recent history of severe human disturbance to Australian forests ensures that reasonably natural forest patches remain and serve as 'models' for many forest categories. They are also refuges for many forest biota extirpated from the wider landscapes as forests are lost, and merit strenuous protection from further changes, and wider efforts to promote connectivity between otherwise isolated remnant patches. In parallel, the recent attention to improving forest insect conservation in harmony with insect pest management continues to benefit from perspectives generated from better-documented faunas elsewhere. Lessons from the northern hemisphere, in particular, have led to revelations of the ecological importance and vulnerability of many insect taxa in forests, together with clear evidence that 'conservation can work' in concert with wider forest uses. A brief outline of the variety of Australian tropical and temperate forests and woodlands, and of the multitude of endemic and, often, highly localised insects that depend on them highlights needs for conservation (both of single focal species and wider forest-dependent radiations and assemblages). The ways in which insects contribute to sustained ecological integrity of these complex ecosystems provide numerous opportunities for practical conservation.

R3,398 Discovery Miles 33 980 Ships in 12 - 19 working days

The contingent valuation technique for measuring the economic value of environmental goods and services has become increasingly popular in recent years and has many advantages over other revealed or stated preference methods. It has been criticised, however, for being inconsistent with economic theory by reflecting altruistic motives and moral obligations. This book examines the role of the 'warmglow' effect (the pleasure derived from giving to good causes or being concerned about the environment) in contingent valuation studies and examines whether warmglow is an underlying force in CV responses. The author argues that if the empirical evidence suggests that warmglow is important, then its magnitude needs to be assessed in the valuation function. The ultimate goal is to disentangle the warmglow effect from the original 'willingness-to-pay' mean estimates and compute a dry estimate, free from any warmglow. The author conducts a CV application in a Portuguese natural park to test the validity of this approach. He tests the premise that the financial contribution by itself constitutes a source of well-being to the respondent and also discusses whether the warm glow component should or should not be included when formulating benefit-cost analysis and environmental policy. This innovative book will be essential reading to all students and scholars of the economics of environmental valuation.

Transportation of species to areas outside their native ranges has been a feature of human culture for millennia. During this time such activities have largely been viewed as beneficial or inconsequential. However, it has become increasingly clear that human-caused introductions of alien biota are an ecological disruption whose consequences rival those of better-known insults like chemical pollution, habitat loss, and climate change. Indeed, the irreversible nature of most alien-species int- ductions makes them less prone to correction than many other ecological problems. Current reshuffling of species ranges is so great that the present era has been referred to by some as the "Homogocene" in an effort to reflect the unique mag- tude of the changes being made. These alien interlopers often cause considerable ecological and economic d- age where introduced. Species extinctions, food-web disruptions, community alte- tions, ecosystem conversion, changes in nutrient cycling, fisheries collapse, watershed degradation, agricultural loss, building damage, and disease epidemics are among the destructive - and frequently unpredictable - ecological and economic effects that invasive alien species can inflict. The magnitude of these damages c- tinues to grow, with virtually all environments heavily used by humans now do- nated by alien species and many "natural" areas becoming increasingly prone to alien invasion as well. Attention to this problem has increased in the past decade or so, and efforts to prevent or limit further harm are gaining wider scientific and political acceptance.

Extending from west Africa to Madagascar, from the vast lowland Congo Basin to the archipelago of forest islands on its eastern rim, the African rain forest is surpassed in size only by the Amazon. This book sheds light on the current efforts to understand and conserve the African rain forest, an area in need of urgent action to save its biological wealth, cultural heritage, and economic potential.

Written by conservation scientists and practitioners based in the African rain forest, the book offers a multidisciplinary perspective that integrates many biological and social sciences. Early chapters trace the forces -- from paleoecological factors to recent human actions -- that have shaped the African forest environment. The next chapters discuss the dominant biological patterns of species ranging from the distinctive elephants, gorillas, and okapi to the less well known birds, butterflies, and amphibians. Other chapters focus on how such different groups as hunter-gatherers, forest farmers, bushmeat hunters, recent immigrants, and commercial foresters have used the forests. Several authors stress the need for tighter links between research and conservation action. The final section draws lessons from the collective experience of those working in an Africa wracked by political strife and economic hardship.

For nearly a quarter century, the polar bears of Churchill were routinely run down and shot by the military, by residents and by conservation officers who were brought in during the late 1960s to protect people. According to one scientist who was there at the time, polar bears were treated more like "great white rats" than the world's largest predator. But then something remarkable happened. During the 1970s the residents of Churchill decided that it was time to find a more peaceful way of living with polar bears.
In the years that followed, scientists conducted studies on the polar bear population and in relatively short order the bears of Churchill became the most studied group of large predators in the world.

'This is an epic journey by a man who’s not only obsessed with birds but who has a deep spiritual connection with the planet as he observes the environments and habitats he encounters.' David Lindo, author of How to be an Urban Birder The (Big) Year Flew By is the tale of one avid birder’s epic, record-breaking adventure through 40 countries over 6 continents – in just one year – to see 6,852 bird species, many on the precipice of extinction. When Arjan Dwarshuis first heard of the ‘Big Year’ – the legendary record for birdwatching – he was just twenty years old. It was midnight, and he was sitting on the roof of a truck high up in the Andean Mountains. In that moment, Arjan made a promise to himself that someday, somehow, he would become a world-record-holding birder. Ten years later, he embarked on an incredible, arduous and perilous journey that took him around the globe; over uninhabited islands, through dense unforgiving rainforests, across snowy mountain peaks and unrelenting deserts – in just a single year. Would he survive? Would he be able to break the ‘Big Year’ record, navigating through a world filled with shifting climate and geopolitical challenges? The (Big) Year that Flew By is an unforgettable, personal exploration of the limits of human potential when engaging with the natural world. It is a book about birds and birding and Arjan’s attempts to raise awareness for critically endangered species, but it is also a book about overcoming mental challenges, extreme physical danger and human competition and fully realizing your passions through nature, adventure and conservation.
