DOWNLOAD EBOOK →Changes in seasonal movements and population dynamics of migratory birds in response to ongoing changes resulting from global climate changes are a topic of great interest to conservation scientists and birdwatchers around the world. Because of their dependence on specific habitats and resources in different geographic regions at different phases of their annual cycle, migratory species are especially vulnerable to the impacts of climate change. In Bird Migration and Global Change, eminent ecologist George W. Cox brings his extensive experience as a scientist and bird enthusiast to bear in evaluating the capacity of migratory birds to adapt to the challenges of a changing climate. Cox reviews, synthesizes, and interprets recent and emerging science on the subject, beginning with a discussion of climate change and its effect on habitat, and followed by eleven chapters that examine responses of bird types across all regions of the globe. The final four chapters address the evolutionary capacity of birds, and consider how best to shape conservation strategies to protect migratory species in coming decades. The rate of climate change is faster now than at any other moment in recent geological history. How best to manage migratory birds to deal with this challenge is a major conservation issue, and Bird Migration and Global Change is a unique and timely contribution to the literature.

These large waterbirds live in North America and make their homes near lakes and ponds. Because of their huge size, trumpeter swans can fight off almost any predator. Get too close to a swan, and you’ll hear the loud honking sound that makes it clear how this big bird got its name. In Trumpeter Swan: The World’s Largest Waterbird, eye-popping color photos paired with simple, grade-appropriate text will engage children as they learn about the natural habitat, physical characteristics, diet, life cycle, and behavior of this supersized animal. A comparison diagram is also included to show readers the animal in relation to a familiar object.

DOWNLOAD EBOOK →This beautiful and inspiring book tells the stories of 80 birds around the world: from the Sociable Weaver Bird in Namibia which constructs huge, multi-nest 'apartment blocks' in the desert, to the Bar-headed Goose of China, one of the highest-flying migrants which crosses the Himalayas twice a year. Many birds come steeped in folklore and myth, some are national emblems and a few have inspired scientific revelation or daring conservation projects. Each has a story to tell that sheds a light on our relationship with the natural world and reveals just how deeply birds matter to us.

DOWNLOAD EBOOK →Managing water resources is one of the most pressing challenges of our times - fundamental to how we feed 2 billion more people in coming decades, eliminate poverty, and reverse ecosystem degradation. This Comprehensive Assessment of Water Management in Agriculture, involving more than 700 leading specialists, evaluates current thinking on water and its interplay with agriculture to help chart the way forward. It offers actions for water management and water policy - to ensure more equitable and effective use. This assessment describes key water-food-environment trends that influence our lives today and uses scenarios to explore the consequences of a range of potential investments. It aims to inform investors and policymakers about water and food choices in light of such crucial influences as poverty, ecosystems, governance, and productivity. It covers rainfed agriculture, irrigation, groundwater, marginal-quality water, fisheries, livestock, rice, land, and river basins. Ample tables, graphs, and references make this an invaluable work for practitioners, academics, researchers, and policymakers in water management, agriculture, conservation, and development.

DOWNLOAD EBOOK →A state-of-the-art photographic field guide to the world's oceanic birds Oceanic birds are among the most remarkable but least known of all birds, living at sea, far from the sight of most people. They offer unusual identification challenges—many species look similar and it can be difficult to get good views of fast-flying birds from a moving boat. The first field guide to the world's oceanic birds in more than two decades, this exciting and authoritative book draws on decades of firsthand experience on the open seas. It features clear text filled with original insights and new information and more than 2,200 carefully chosen color images that bring the ocean and its remarkable winged inhabitants to life. Never before have oceanic birds been presented in such an accessible and comprehensive way. The introduction discusses the many recent developments in seabird taxonomy, which are incorporated into the species accounts, and these accounts are arranged into groups that aid field identification. Each group and species complex has an introductory overview of its identification challenges, illustrated with clear comparative photos. The text describes flight manner, plumage variation related to age and molt, seasonal occurrence patterns, migration routes, and many other features. The result is an indispensable guide for exploring birding's last great frontier. A comprehensive, authoritative, and accessible guide to oceanic birds Covers more than 270 species Includes more than 2,200 color photos with concise captions noting key features Features careful species comparisons, overviews of the latest taxonomy, tips on how to observe and ID birds at sea, and much more
