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.
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.
'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.

 Watch a thousand years unfold in the life of one magnificent tree! A thousand years ago, a tiny acorn fell to the ground. As the years pass, it grows . . . and GROWS into an enormous oak tree! As the centuries sweep by, children play games around the tree. Families dance about it. A fleeing king even hides inside its hollow trunk! The tree gives food and shelter to a host of animals, from squirrels and badgers to birds and beetles. After a thousand years, the ancient tree finally falls in a storm - but a new acorn sprouts, and the cycle of life begins all over again. The tree's magical life story is brought to life in Julia Donaldson's rich, dramatic rhyme. Victoria Sandøy's gorgeous, atmospheric illustrations perfectly capture the changing seasons, and the people and wildlife that pass by Children will love spotting all the creatures in the pictures, and seeing the games children play around the tree This is a book that encourages us all to look more closely at nature, and to appreciate the wonder of our ancient trees. The final pages of the book contain extra fascinating facts about oak trees and the animals that depend on them. Praise for The Christmas Pine, also by Julia Donaldson and Victoria Sandøy: "Magical . . . as well as paying tribute to tradition, the gentle rhythmic verse and stunning pictures illuminate the two other things close to Julia's heart: the power of children and song" Julia Donaldson is the author of many of the best-loved children's books ever written. She has been awarded a CBE for services to literature, and is the most celebrated children's writer in Britain today. Many of Julia Donaldson's beloved picture books have been made into award-winning animated films which are regularly shown on the BBC at Christmas.

The book presents a collection of large-scale network-modeling studies on coastal systems in Latin America. It includes a novel description of the functioning of coastal complex ecosystems and also predicts how natural and human-made disturbances percolate through the networks. Coastal areas belong to the most populated ecosystems around the globe, and are massively influenced by human impacts such as shipping, mining, fisheries, tourism, pollution and human settlements. Even though many of these activities have facilitated socio-economic development, they have also caused a significant deterioration in natural populations, communities and ecosystems worldwide. Covering coastal marine ecosystems of Latin America such as the NE and SE Pacific, NW Atlantic and Caribbean areas, it discusses the construction of quantitative (Ecopath-Ecosim-Ecospace and Centrality of Node Sets) and semi-quantitative (Loop Analysis) multispecies trophic-network models to describe and assess the impacts of natural and human interventions like pelagic and benthic fishing as well as natural events such as El Nino, and La Nina. The book also features steady state (and/or near moving equilibrium) and dynamical models to support the management of exploited organisms, and applies and quantifies macroscopic indices, based on Ascendency (Ulanowicz) and Local Stability (Levins Loop Analysis). Further, it discusses the determination of the Keystone Species Complex Index, which is a holistic extension of the classical concept of Keystone Species (Paine), offering novel strategies for conservation monitoring and management.
Myth and media typically cast animals we consider predators or carnivores as unthinking killers-dangerous, unpredictable, and devoid of emotion. But is this portrait valid? By exploring their inner lives, this pioneering book refutes the many misperceptions that hide the true nature of these animals. We discover that great white sharks express tender maternal feelings, rattlesnakes make friends, orcas abide by an ancient moral code, and much more. Using the combined lenses of natural history, neuroscience, and psychology, G. A. Bradshaw describes how predators share the rainbow of emotions that humans experience, including psychological trauma. Renowned for leading research on post-traumatic stress disorder (PTSD) in elephants and other species, Bradshaw decries the irrational thinking behind wildlife policies that equate killing carnivores with "conservation." In its place, she proposes a new, ethical approach to coexistence with the planet's fiercest animals.
The waters of the Indo-Pacific were at the centre of the global expansion of marine capture fisheries in the twentieth century, yet surprisingly little has been written about this subject from a historical perspective. This book, the first major study of the history of fishing in Asia and Oceania, presents the case-studies completed through the History of Marine Animal Populations (HMAP) initiative. It examines the marine environmental history and historical marine ecology of the Indo-Pacific during a period that witnessed the dramatic escalation of industrial fishing in these seas.
Sturgeons are considered living fossils, sharing many morphological and biological features with ancestral fish. Furthermore, sturgeons are of the utmost interest from an economic perspective, not only for the caviar but for the flesh. However, the wild populations of the majority of the species are at serious risk of extinction all over the world. So, it is urgent to develop strategies for both farming culture and conservation and recovery in natural habitats. This book provides a comprehensive view of the biology and sustainable development of sturgeons putting emphasis on the Southern Europe autochthonous species such as Acipenser nacarii and Acipenser sturio that share geographical distribution. Other relevant species (such as Huso huso, A. oxyrhinchus, A. ruthenus, A. stellatus) and areas (Germany, Russia, North America) are also considered. The contents are organised in three sections: Taxonomy and Biogeography (including the morphological and genetic analyses that clarify the taxonomy and phylogeny of sturgeons, focused on those from Southern Europe), Biology and Aquaculture (where several aspects of the developmental biology, feeding, and reproduction are considered in relation to the improvement of sturgeon farming), and Recovery and Conservation (that collates and analyses different recovery research actions, the ecology of the rivers for restoration as well as the problems related to the trade of caviar)."
Among the deep-sea marine invertebrates, pycnogonids and crustaceans represent ecologically important and most diverse groups of species. Yet both are still poorly understood. Sampling and exploring operations off the west and east coast of the Americas has significantly increased in the last two decades. However such operations are very costly and limited in number and frequency. In countries like Brazil, Canada, Chile, Colombia, Costa Rica, Mexico, Peru, the United States of America, and El Salvador a large effort has been made to explore the deep-sea resources and the rich diversity of the communities, resulting in a better understanding of the natural ecosystems on both coasts of America. Pycnogonids and many groups of deep-sea crustaceans have been intensively studied, from the smallest animals, like the mostly unknown benthic copepods to the largest decapods. This book presents new and updated information on various groups of deep-sea pycnogonids and crustaceans occurring off the American continent. Offering a valuable reference resource for scientists interested in this fascinating fauna, it includes review papers and new data on the deep-sea communities occurring off the USA, Mexico, El Salvador, Costa Rica, Colombia, Chile, Peru, Brazil and Argentina, as well as in larger areas in both the East Pacific and the West Atlantic. As such it covers most of the current deep-water research in Latin America.
"Planet Without Apes" demands that we consider whether we can live with the consequences of wiping our closest relatives off the face of the Earth. Leading primatologist Craig Stanford warns that extinction of the great apes chimpanzees, bonobos, gorillas, and orangutans threatens to become a reality within just a few human generations. We are on the verge of losing the last links to our evolutionary past, and to all the biological knowledge about ourselves that would die along with them. The crisis we face is tantamount to standing aside while our last extended family members vanish from the planet. Stanford sees great apes as not only intelligent but also possessed of a culture: both toolmakers and social beings capable of passing cultural knowledge down through generations. Compelled by his field research to take up the cause of conservation, he is unequivocal about where responsibility for extinction of these species lies. Our extermination campaign against the great apes has been as brutal as the genocide we have long practiced on one another. Stanford shows how complicity is shared by people far removed from apes shrinking habitats. We learn about extinction s complex links with cell phones, European meat eaters, and ecotourism, along with the effects of Ebola virus, poverty, and political instability. Even the most environmentally concerned observers are unaware of many specific threats faced by great apes. Stanford fills us in, and then tells us how we can redirect the course of an otherwise bleak future."
Wild salmon, trout, char, grayling, and whitefish (collectively salmonids) have been a significant local food and cultural resource for Pacific Northwest peoples for millennia. The location, size, and distribution of urban areas along streams, rivers, estuaries, and coasts directly and indirectly alter and degrade wild salmonid populations and their habitats. Although urban and exurban areas typically cover a smaller fraction of the landscape than other land uses combined, they have profound consequences for local ecosystems, aquatic and terrestrial populations, and water quality and quantity.
Keith Culver and David Castle Introduction Aquaculture is at the leading edge of a surprisingly polarized debate about the way we produce our food. According to the United Nations Food and Agriculture Organization, aquaculture production has increased 8. 8% per year since 1970, far surpassing productivity gains in terrestrial meat production at 2. 8% in the same period (FAO 2007). Like the 'green revolution' before it, the 'blue revolution' in aquaculture promises rapidly increased productivity through technology-driven - tensi?cation of aquaculture animal and plant production (Costa-Pierce 2002; The Economist 2003). Proponents of further aquaculture development emphasize aq- culture's ancient origins and potential to contribute to global food security d- ing an unprecedented collapse in global ?sheries (World Fish Center; Meyers and Worm 2003; Worm et al. 2006). For them, technology-driven intensi?cation is an - dinary and unremarkable extension of past practice. Opponents counter with images of marine and freshwater environments devastated by intensive aquaculture pr- tices producing unsustainable and unhealthy food products. They view the promised revolutionasascam, nothingmorethanclever marketingbypro?t-hungry ?shfa- ers looking for ways to distract the public from the real harms done by aquaculture. The stark contrast between proponents and opponents of modern aquaculture recalls decades of disputes about intensive terrestrial plant and animal agriculture, disputes whose vigor shows that the debate is about much more than food production (Ruse and Castle 2002).
" This volume] presents an admirable set of case studies on the effects of modern conservation projects on local peoples from across the globe. The great strength of the volume lies in the diversity of cases." - International Journal of African Historical Studies ." . . this book will be the source material for future generations of researchers . . . The many arguments in this book will challenge and hopefully bring forward vigorous debate about the aims and goals of sustainable development and conservation tools." - The Indigenous Nations Studies Journal Wildlife conservation and other environmental protection projects can have tremendous impact on the lives and livelihoods of the often mobile, difficult-to-reach, and marginal peoples who inhabit the same territory. The contributors to this collection of case studies, social scientists as well as natural scientists, are concerned with this human element in biodiversity. They examine the interface between conservation and indigenous communities forced to move or to settle elsewhere in order to accommodate environmental policies and biodiversity concerns. The case studies investigate successful and not so successful community-managed, as well as local participatory, conservation projects in Africa, the Middle East, South and South Eastern Asia, Australia and Latin America. There are lessons to be learned from recent efforts in community managed conservation and this volume significantly contributes to that discussion. Dawn Chatty is General Editor of Studies in Forced Migration and teaches at the Center for Refugee Studies of the University of Oxford. Marcus Colchester works for the Forest Peoples Programme.
Contingent Valuation and Endangered Species provides a comprehensive and rigorous examination of the contingent valuation method as applied to the profound social problem of biodiversity conservation.The contingent valuation method allows the explicit identification and valuation of the non-use values of species in a way which has not been possible before. This new book offers a rigorous state-of-the-art evaluation of the theoretical and statistical issues central to the contingent valuation method as well as a hands-on account of the design, implementation and analysis of contingent valuation surveys of the benefits of species conservation. Contingent Valuation and Endangered Species includes a comprehensive account of efforts at endangered species protection in Australia and New Zealand as well as current developments in the United States. This comprehensive appraisal of the problems and economics of biodiversity conservation will be welcomed by researchers and practitioners as an explicit hands-on application of the contingent valuation method.
This book is the first to present in a systematic manner the application of game theory to fisheries management at both international and national levels. Strategic interaction among fishers and nations exploiting fishery resources is an inescapable fact of life. This has long been recognized at the international level, and is becoming increasingly recognized at the national/regional level. It follows, therefore, that, in order to be able to analyse effectively the management of these resources, the theory of strategic interaction game theory must be brought to bear. In this book the step-by-step development of the game theory is accompanied by numerous applications to the real world of fisheries management policy. As such, it is designed to appeal to policy makers and stakeholders, as well as to graduate students in Economics. |
