Book Description
Migration is one of the most fascinating and dramatic of all animal behaviors. Historically, however, the study of migration has been fragmented, with ornithologists, entomologists, and marine biologists paying little attention to work outside their own fields. This treatment of the subject shows how comparisons across taxa can in fact illuminate migratory life cycles and the relation of migration to other movements. The book thus takes an integrated ecological perspective, focusing on migration as a biological phenomenon. The work is divided into four parts, each with a brief introductory section. Part I defines migration, gives examples, and places migration in the spectrum of movement behaviors, concluding with a chapter on methods for its study. Part II focuses on proximate mechanisms, including physiology and morphology (and the constraints associated with them), the interactions between migration and wind and current patterns, and the various orientation and navigation mechanisms by which migrants find their way about. Part III on the evolution of migratory life histories addresses the evolutionary and ecological basis for migration and the roles of migration not only in the lives of organisms, but also in the ecological communities in which they live. Part IV is devoted to a brief consideration of migration and its relation to pest management and conservation. As a major contribution to a vital subject, this work will be valued by all researchers and students in the field of animal behavior, ecology, and zoology.

Book Description
Migration, broadly defined as directional movement to take advantage of spatially distributed resources, is a dramatic behaviour and an important component of many life histories that can contribute to the fundamental structuring of ecosystems. In recent years, our understanding of migration has advanced radically with respect to both new data and conceptual understanding. It is now almost twenty years since publication of the first edition, and an authoritative and up-to-date sequel that provides a taxonomically comprehensive overview of the latest research is therefore timely. The emphasis throughout this advanced textbook is on the definition and description of migratory behaviour, its ecological outcomes for individuals, populations, and communities, and how these outcomes lead to natural selection acting on the behaviour to cause its evolution. It takes a truly integrative approach, showing how comparisons across a diversity of organisms and biological disciplines can illuminate migratory life cycles, their evolution, and the relation of migration to other movements. Migration: The Biology of Life on the Move focuses on migration as a behavioural phenomenon with important ecological consequences for organisms as diverse as aphids, butterflies, birds and whales. It is suitable for senior undergraduate and graduate level students taking courses in behaviour, spatial ecology, 'movement ecology', and conservation. It will also be of interest and use to a broader audience of professional ecologists and behaviourists seeking an authoritative overview of this rapidly expanding field.

Book Description
'A dazzlingly original picture of our relentlessly mobile species' NAOMI KLEIN 'Fascinating . . . Likely to prove prophetic in the coming months and years' OBSERVER 'A dazzling tour through 300 years of scientific history' PROSPECT 'A hugely entertaining, life-affirming and hopeful hymn to the glorious adaptability of life on earth' SCOTSMAN __________________ We are surrounded by stories of people on the move. Wild species, too, are escaping warming seas and desiccated lands in a mass exodus. Politicians and the media present this upheaval of migration patterns as unprecedented, blaming it for the spread of disease and conflict, and spreading anxiety across the world as a result. But the science and history of migration in animals, plants, and humans tell a different story. Far from being a disruptive behaviour, migration is an ancient and lifesaving response to environmental change, a biological imperative as necessary as breathing. Climate changes triggered the first human migrations out of Africa. Falling sea levels allowed our passage across the Bering Sea. Unhampered by borders, migration allowed our ancestors to people the planet, into the highest reaches of the Himalayan Mountains and the most remote islands of the Pacific, disseminating the biological, cultural and social diversity that ecosystems and societies depend upon. In other words, migration is not the crisis – it is the solution. __________________ Tracking the history of misinformation from the 18th century through to today's anti-immigration policies, The Next Great Migration makes the case for a future in which migration is not a source of fear, but of hope.

Book Description
“Just astonishing . . . Our natural navigational capacities are no match for those of the supernavigators in this eye-opening book.”—Frans de Waal, The New York Times Book Review Publisher's note: Supernavigators was published in the UK under the title Incredible Journeys. Animals plainly know where they’re going, but how they know has remained a stubborn mystery—until now. Supernavigators is a globe-trotting voyage of discovery alongside astounding animals of every stripe: dung beetles that steer by the Milky Way, box jellyfish that can see above the water (with a few of their twenty-four eyes), sea turtles that sense Earth’s magnetic field, and many more. David Barrie consults animal behaviorists and Nobel Prize–winning scientists to catch us up on the cutting edge of animal intelligence—revealing these wonders in a whole new light.

Book Description
Animal migration is a magnificent sight: a mile-long blanket of cranes rising from a Nebraska river and filling the sky; hundreds of thousands of wildebeests marching across the Serengeti; a blaze of orange as millions of monarch butterflies spread their wings to take flight. Nature’s great migrations have captivated countless spectators, none more so than premier ecologist David S. Wilcove. In No Way Home, his awe is palpable—as are the growing threats to migratory animals. We may be witnessing a dying phenomenon among many species. Migration has always been arduous, but today’s travelers face unprecedented dangers. Skyscrapers and cell towers lure birds and bats to untimely deaths, fences and farms block herds of antelope, salmon are caught en route between ocean and river, breeding and wintering grounds are paved over or plowed, and global warming disrupts the synchronized schedules of predators and prey. The result is a dramatic decline in the number of migrants. Wilcove guides us on their treacherous journeys, describing the barriers to migration and exploring what compels animals to keep on trekking. He also brings to life the adventures of scientists who study migrants. Often as bold as their subjects, researchers speed wildly along deserted roads to track birds soaring overhead, explore glaciers in search of frozen locusts, and outfit dragonflies with transmitters weighing less than one one-hundredth of an ounce. Scientific discoveries and advanced technologies are helping us to understand migrations better, but alone, they won’t stop sea turtles and songbirds from going the way of the bison or passenger pigeon. What’s required is the commitment and cooperation of the far-flung countries migrants cross—long before extinction is a threat. As Wilcove writes, “protecting the abundance of migration is key to protecting the glory of migration.” No Way Home offers powerful inspiration to preserve those glorious journeys.

Book Description
Why do Mexicans migrate to the United States? Is there a typical Mexican migrant? Beginning in the 1970s, survey data indicated that the average migrant was a young, unmarried man who was poor, undereducated, and in search of better employment opportunities. This is the general view that most Americans still hold of immigrants from Mexico. On the Move argues that not only does this view of Mexican migrants reinforce the stereotype of their undesirability, but it also fails to capture the true diversity of migrants from Mexico and their evolving migration patterns over time. Using survey data from over 145,000 Mexicans and in-depth interviews with nearly 140 Mexicans, Filiz Garip reveals a more accurate picture of Mexico-U.S migration. In the last fifty years there have been four primary waves: a male-dominated migration from rural areas in the 1960s and '70s, a second migration of young men from socioeconomically more well-off families during the 1980s, a migration of women joining spouses already in the United States in the late 1980s and ’90s, and a generation of more educated, urban migrants in the late 1990s and early 2000s. For each of these four stages, Garip examines the changing variety of reasons for why people migrate and migrants’ perceptions of their opportunities in Mexico and the United States. Looking at Mexico-U.S. migration during the last half century, On the Move uncovers the vast mechanisms underlying the flow of people moving between nations.

Book Description
Moving Matters is a richly nuanced portrait of the serial migrant: a person who has lived in several countries, calling each one at some point "home." The stories told here are both extraordinary and increasingly common. Serial migrants rarely travel freely—they must negotiate a world of territorial borders and legal restrictions—yet as they move from one country to another, they can use border-crossings as moments of self-clarification. They often become masters of settlement as they turn each country into a life chapter. Susan Ossman follows this diverse and growing population not only to understand how paths of serial movement produce certain ways of life, but also to illuminate an ongoing tension between global fluidity and the power of nation-states. Ultimately, her lyrical reflection on migration and social diversity offers an illustration of how taking mobility as a starting point fundamentally alters our understanding of subjectivity, politics, and social life.

Book Description
Migration on the Move examines the dynamics of migration and asylum law over the past two decades and highlights profound changes that have taken place in these fields as a result of growing EU competences to deal with migration and asylum questions. The book maps the transformation of the migration field by focusing on three interrelated issues: the effects of Europeanization and the shifting power relations that it implies; placing Europe’s laws and policies in a global migration context, and critically examining to whom ‘project’ Europe belongs. The contributors offer a multidisciplinary analysis of key aspects of the migration and refugee crisis and their implications for policies, principles of law, and the treatment of people in Europe today.
