More than a quarter of bird species are concentrated in areas that together make up just one per cent of the earth's land surface. These restricted range species include almost three-quarters of all threatened birds. BirdLife International has identified 218 Endemic Bird Areas (EBAs), which hold at least two restricted range species, although some support more than 60. EBAs provide a reasonable overlap with the biodiversity hotspots identified by other conservation organisations, and are a focus for conservation action. At the heart of this book are descriptions of all 218 EBAs, including key habitats, major threats and conservation initiatives and a detailed map. Tables list the restricted-range bird species present, with their global status, habitat requirements and distribution. Introductory sections present global and regional overviews. The authors discuss the wider conservation relevance of EBAs, including why birds are good indicators of biodiversity, and how EBAs can be used effectively to influence policy-makers.

Descreve como a grande variedade de espécies selvagens e únicas habitam uma parte muito pequena do mundo e os resultados reais da análise da distribuição de pássaros mostram padrões gerais e por regiões para descrever filiação política, altitude e habitats para cada Áreas de Pássaros Endêmicos (EBA).
"This beautifully illustrated book vividly depicts the most threatened birds on Earth. It provides up-to-date information from BirdLife International on the threats each species faces, and the measures being taken to save them. Today, 590 bird species are classified as Endangered or Critically Endangered, or now only exist in captivity. This landmark publication features stunning photographs of 515 of these species--including the results of a prestigious international photographic competition organized specifically for this book. This is the first time that images of many of these birds have been published. It also showcases meticulously accurate illustrations by acclaimed wildlife artist Tomasz Cofta for the 75 species of which no photographs are known to exist. The World's Rarest Birds has introductory chapters that explain the threats birds face in a rapidly changing world, how their threat status is assessed, and how this information is used to set conservation priorities."--Jacket.
This book draws together a wide range of papers from researchers around the world that address the conservation and biodiversity of vertebrates, particularly those in terrestrial habitats. Collectively, the papers provide a snap-shot of the types of studies and actions being taken in vertebrate conservation and provide topical examples that will make the volume especially valuable for use in conservation biology courses.
This book discusses current knowledge and challenges with the ecological management and conservation of wetlands, with a focus on the East Kolkata Wetlands of India. This area is referred to as a Ramsar Site, a designation given to areas with special protection statuses, since it is the largest natural waste recycling system in the world. The site faces many threats to its biodiversity and ecosystem functioning due to anthropogenic activity in the region, and therefore an assessment of the ecosystem services, bio-ecological uniqueness, and issues stemming from climate change and human impacts is needed to develop protection strategies for the future ecological functioning and sustainability of the wetlands. The authors use GIS and remote sensing techniques to assess and monitor harmful industrial and environmental impacts on the wetlands, and to inform mitigation and conservation strategies in the face of ongoing threats such as pollution, habitat destruction and bioinvasion. The book also highlights various social and economic aspects tied to the functioning and management of the wetlands, along with ecological, biological, and physio-chemical considerations. The study will be of use to students and researchers in aquatic ecology, biodiversity, and environmental sustainability and conservation, as well as to environmental planners, engineers, and policymakers.
The context in which environmental policy decision-making occurs has changed, resulting from widening environmental problems, increased demands from groups and citizens, continuing pressure on the continent's resources and normative shifts. The complexity of current issues is related to an even broader contextual shift: the globalization of environmental issues exacerbated by trade liberalization, especially on a regional level and the potential contradictions between trade and the environmental international agenda that this implies. This volume studies the new dimensions of resource conflict between Canada and the United States, accounting for the emergence of new bilateral environmental issues and detailing how trade liberalization has fostered both disputes and policy convergence. It also examines the recent shifts in America towards a unilateral foreign policy and how this affects active Canadian diplomacy Ideal as a resource tool for students and academics, this book will be a key resource in the areas of global governance, US-Canadian foreign policy and environmental policy.
This contributed volume presents an analysis of the current conservation status of major faunal groups in Mexico. The chapters describe a prognosis of future challenges, and also explore the expanding threats inherent in the Anthropocene within the context of the unique physical, biological and cultural aspects of the nation. Covering 27 chapters, and written by Mexican and international authors, this book analyzes a wide range of vertebrate and invertebrate animal taxa, their ecosystems and the critical processes related to their present conservation status. This volume is an important reference material for researchers, conservationists and students interested in the biological and ecological processes shaping the Mexican fauna.
