This best-selling majors ecology book continues to present ecology as a series of problems for readers to critically analyze. No other text presents analytical, quantitative, and statistical ecological information in an equally accessible style. Reflecting the way ecologists actually practice, the book emphasizes the role of experiments in testing ecological ideas and discusses many contemporary and controversial problems related to distribution and abundance. Throughout the book, Krebs thoroughly explains the application of mathematical concepts in ecology while reinforcing these concepts with research references, examples, and interesting end-of-chapter review questions. Thoroughly updated with new examples and references, the book now features a new full-color design and is accompanied by an art CD-ROM for instructors. The field package also includes The Ecology Action Guide, a guide that encourages readers to be environmentally responsible citizens, and a subscription to The Ecology Place (www.ecologyplace.com), a web site and CD-ROM that enables users to become virtual field ecologists by performing experiments such as estimating the number of mice on an imaginary island or restoring prairie land in Iowa. For college instructors and students.

Craig Packer takes us into Africa for a journey of fifty-two days in the fall of 1991. But this is more than a tour of magnificent animals in an exotic, faraway place. A field biologist since 1972, Packer began his work studying primates at Gombe and then the lions of the Serengeti and the Ngorongoro Crater with his wife and colleague Anne Pusey. Here, he introduces us to the real world of fieldwork—initiating assistants to lion research in the Serengeti, helping a doctoral student collect data, collaborating with Jane Goodall on primate research. As in the works of George Schaller and Cynthia Moss, Packer transports us to life in the field. He is addicted to this land—to the beauty of a male lion striding across the Serengeti plains, to the calls of a baboon troop through the rain forests of Gombe—and to understanding the animals that inhabit it. Through his vivid narration, we feel the dust and the bumps of the Arusha Road, smell the rosemary in the air at lunchtime on a Serengeti verandah, and hear the lyrics of the Grateful Dead playing off bootlegged tapes. Into Africa also explores the social lives of the animals and the threats to their survival. Packer grapples with questions he has passionately tried to answer for more than two decades. Why do female lions raise their young in crèches? Why do male baboons move from troop to troop while male chimps band together? How can humans and animals continue to coexist in a world of diminishing resources? Immediate demands—logistical nightmares, political upheavals, physical exhaustion—yield to the larger inescapable issues of the interdependence of the land, the animals, and the people who inhabit it.

Earth is home to an estimated 8 million animal species, 600,000 fungi, 300,000 plants, and an undetermined number of microbial species. Of these animal, fungal, and plant species, an estimated 75% have yet to be identified. Moreover, the interactions between these species and their physical environment are known to an even lesser degree. At the same time, the earth’s biota faces the prospect of climate change, which may manifest slowly or extremely rapidly, as well as a human population set to grow by two billion by 2045 from the current seven billion. Given these major ecological changes, we cannot wait for a complete biota data set before assessing, planning, and acting to preserve the ecological balance of the earth. This book provides comprehensive coverage of the scientific and engineering basis of the systems ecology of the earth in 15 detailed, peer-reviewed entries written for a broad audience of undergraduate and graduate students as well as practicing professionals in government, academia, and industry. The methodology presented aims at identifying key interactions and environmental effects, and enabling a systems-level understanding even with our present state of factual knowledge.

This text is for students who are entering graduate-level studies in their academic fields and/or who need to write research results in the form of technical papers, journal articles, theses, or dissertations.

How will patterns of human interaction with the earth's eco-system impact on biodiversity loss over the long term--not in the next ten or even fifty years, but on the vast temporal scale be dealt with by earth scientists? This volume brings together data from population biology, community ecology, comparative biology, and paleontology to answer this question.

Prior to 2011, popular imagination perceived the Muslim Middle East as unchanging and unchangeable, frozen in its own traditions and history. In Life as Politics, Asef Bayat argues that such presumptions fail to recognize the routine, yet important, ways in which ordinary people make meaningful change through everyday actions. First published just months before the Arab Spring swept across the region, this timely and prophetic book sheds light on the ongoing acts of protest, practice, and direct daily action. The second edition includes three new chapters on the Arab Spring and Iran's Green Movement and is fully updated to reflect recent events. At heart, the book remains a study of agency in times of constraint. In addition to ongoing protests, millions of people across the Middle East are effecting transformation through the discovery and creation of new social spaces within which to make their claims heard. This eye-opening book makes an important contribution to global debates over the meaning of social movements and the dynamics of social change.

Covering American transgender history from the mid-twentieth century to today, Transgender History takes a chronological approach to the subject of transgender history, with each chapter covering major movements, writings, and events. Chapters cover the transsexual and transvestite communities in the years following World War II; trans radicalism and social change, which spanned from 1966 with the publication of The Transsexual Phenomenon, and lasted through the early 1970s; the mid-'70s to 1990-the era of identity politics and the changes witnessed in trans circles through these years; and the gender issues witnessed through the '90s and '00s. Transgender History includes informative sidebars highlighting quotes from major texts and speeches in transgender history and brief biographies of key players, plus excerpts from transgender memoirs and discussion of treatments of transgenderism in popular culture.
