In its first English-language edition, this book introduces the many-faceted interactions of animal populations with their habitats. From soil fauna, ants and termites to small and large herbivores, burrowing mammals and birds, the author presents a comprehensive analysis of animals and ecosystems that is as broad and varied as all nature. Chapter 2 addresses the functional role of animals in landscape ecosystems, emphasizing fluxes of energy and matter within and between ecosystems, and the effects of animals on qualitative and structural habitat change. Discussion includes chapters on the role of animal population density and the impacts of native herbivores on vegetation and habitats from the tropics to the polar regions. Cyclic mass outbreaks of species such as the larch bud moth in Switzerland, the mountain pine beetle and the African red-billed weaver bird are described and analyzed. Other chapters discuss Zoochory – the dispersal of seeds by ants, mammals and birds – and the influence of burrowing animals on soil development and geomorphology. Consideration extends to the impact of feral domestic animals. Chapter 5 focuses on problems resulting from introduction of alien animals and from re-introduction of animal species to their original habitats, discusses the effects on ecosystems of burrowing, digging and trampling by animals. The author also addresses keystone species such as kangaroo rats, termites and beavers. Chapter 6 addresses the role of animals in landscape management and nature conservation, with chapters on the impact of newcomer species such as animals introduced into Australia, New Zealand and Europe, and the consequences of reintroduction of species to original habitat. It also discusses the carrying capacity of natural habit, public attitudes toward conversation and more. The final section ponders the effects of climate on interactions between animals and their habitats.

What is the best way to survive when the going gets tough? Hiding underground. From penguins to dinosaurs, trilobites, and humans, Anthony Martin reveals the subterranean secret of survival. Humans have “gone underground” for survival for thousands of years, from underground cities in Turkey to Cold War–era bunkers. But our burrowing roots go back to the very beginnings of animal life on earth. Without burrowing, the planet would be very different today. Many animal lineages alive now—including our own—only survived a cataclysmic meteorite strike 65 million years ago because they went underground. On a grander scale, the chemistry of the planet itself had already been transformed many millions of years earlier by the first animal burrows, which altered whole ecosystems. Every day we walk on an earth filled with an under-ground wilderness teeming with life. Most of this life stays hidden, yet these animals and their subterranean homes are ubiquitous, ranging from the deep sea to mountains, from the equator to the poles. Burrows are a refuge from predators, a safe home for raising young, or a tool to ambush prey. Burrows also protect animals against all types of natural disasters: fires, droughts, storms, meteorites, global warmings—and coolings. In a book filled with spectacularly diverse fauna, acclaimed paleontologist and ichnologist Anthony Martin reveals this fascinating, hidden world that will continue to influence and transform life on this planet.

This book offers a multidimensional comparative analysis of two large groups of the world's displaced populations : resettlers uprooted by development and refugees fleeing military conflicts or natural calamities. The authors explore common central issues: the condition of being "displaced," the risks of impoverishment and destitu-tion, the rights and entitlements of those uprooted, and, most important, the means of reconstruction of their livelihoods. (Adapté de l'Introduction).

Each year, thousands of Chinese children, primarily abandoned infant girls, are adopted by Americans. Yet we know very little about the local and transnational processes that characterize this new migration. Transnational Adoption is a unique ethnographic study of China/U.S. adoption, the largest contemporary intercountry adoption program. Sara K. Dorow begins by situating the popularity of the China/U.S. adoption process within a broader history of immigration and adoption. She then follows the path of the adoption process: the institutions and bureaucracies in both China and the United States that prepare children and parents for each other; the stories and practices that legitimate them coming together as transnational families; the strains placed upon our common notions of what motherhood means; and ways in which parents then construct the cultural and racial identities of adopted children. Based on rich ethnographic evidence, including interviews with and observation of people on both sides of the Pacific—from orphanages, government officials, and adoption agencies to advocacy groups and adoptive families themselves—this is a fascinating look at the latest chapter in Chinese-American migration.

A Companion to Qualitative Research draws on the work of an array of leading scholars from Europe, Britain and North America to present a summary of every aspect of the qualitative research process from nuts-and-bolts methods and research styles, to examinations of methodological theory and epistemology. It is one of the few surveys of qualitative research to adopt a genuinely international voice.

For more than 40 years I have been engaged in timberline research. Thus, one could suppose that writing this book should not have been too difficult. It was harder, however, than expected, and in the end I felt that more questions had arisen than could be answered within its pages. Perhaps it would have been easier to write the book 30 years ago and then leave the subject to mature. Lastly it was the late Prof. Heinz Ellenberg who had convinced me to portray a much needed and complete picture of what we know of the timberline with special respect to its great physiognomic, structural and ecological variety. The first version of this book was p- lished in the German language (Holtmeier, 2000). Nevertheless, I was very delighted when Prof. Martin Beniston encouraged me to prepare an English edition for the series ‘Advances in Global Change Research’, which guaranteed a wider circulation. Timberline is a worldwide and very heterogeneous phenomenon, which can only be presented by way of examples. My own field experience is necessarily limited to certain timberline areas, such as the Alps, northern Scandinavia, northern Finland and many high mountain ranges in the western United States and Canada. However, my own observations and the results of my and my previous collaborators research were essential for developing the concept of the book and became integrated into the picture of timberline that is presented in the following chapters.
