The collision of the Indian and Eurasian plates around fifty million years ago profoundly altered earth's geography and regional climates. The rise of the Himalaya led to intensification of the monsoon, the birth of massive glaciers and turbulent rivers, and an efflorescence of ecosystems along the most extreme elevational gradient on Earth. When the Ice Age ended, humans became part of this mix, and today nearly one quarter of the world's population inhabits its river basins, from Afghanistan to Myanmar. Life in the Himalaya examines the region's geophysical and biological systems and explores the past and future of human sustainability in the mountain's shadow. Maharaj Pandit divides the Himalaya's history into four phases. During the first, the mountain and its ecosystems formed. In the second, humans altered the landscape, beginning with nomadic pastoralism, continuing to commercial deforestation, and culminating in pockets of resistance to forest exploitation. The third phase saw a human population explosion, accompanied by road and dam building and other large-scale infrastructure that degraded ecosystems and caused species extinctions. Pandit outlines a future networking phase which holds the promise of sustainable living within the mountain's carrying capacity. Today, the Himalaya is threatened by recurrent natural disasters and is at risk of catastrophic loss of life. If humans are to have a sustainable future there, Pandit argues, they will need to better understand the region's geological vulnerability, ecological fragility, and sociocultural sensitivity. Life in the Himalaya outlines the mountain's past in order to map a way forward.

This book presents modern approaches for understanding the evolution and diversification of land plants, one of the most exciting areas of plant systematics. It consists of three sections: origin and diversification of primitive land plants; origin and diversification of angiosperms; speciation and mechanisms of diversification. These sections correspond to the three major areas in the evolution of plants. In each section, data from molecular, morphological, and paleontological approaches are presented. Each author introduces recent progress and new findings, and proposes future research. For example, the morphological evolution of reproductive organs, or flowers in angiosperms, is now being clarified from the molecular genetic point of view through the study of regulatory genes such as MADS gene family. With this book, readers can readily understand the state-of-the-art in plant systematics and become aware of prospective future problems.

The definitive guide to California's diverse array of lichen flora, with color photographs and descriptions of over 500 species Lichens are among the most colorful and abundant organisms in the world. They provide food and nesting material for a wide variety of wildlife, contribute nutrients to the soil, and are indicators of both undisturbed ecosystems and clean air. They lend color and pattern to trees, shrubs, and rocks, yet most people know little about them. This richly illustrated, authoritative guide to the lichens of California draws new attention to these striking and ecologically important organisms, which are symbionts-representing a relationship between a fungus and alga-and highlights their beauty, diversity, and value as a natural resource. Lichens are especially abundant and varied in California, where climates range from temperate rainforests to arid deserts. A Field Guide to California Lichens features stunning new photographs of some 500 lichen species by award-winning nature photographer Stephen Sharnoff. Up-to-date descriptions accompany each illustration. Among the special contributions of the guide are its coverage of most common macrolichens in California and its inclusion of many of the crust-forming species. For land management professionals and scientists involved with ecosystem studies, for birders, hikers, and all others curious about the natural world around them, this book will be a welcome field companion.

What is the origin of the universe? How did life appear on Earth and why was much of that life destroyed at various times in Earth's history? In this book four noted scientists-physicist Alan H. Guth, astronomer George Wetherill, biologist Lynn Margulis, and paeleobiologist David Raup- propose answers to these questions, discussing the newest developments in some exciting areas of current research. "Comprises four excellent essays. . . . The authors of this book seek to elucidate the remote, unusual events that most influenced the history of the cosmos and the earth. They describe alternative models and the evidence on which these models are based."-Laurie R. Godfrey, Science Books and Films "For a scientist who specializes in cosmology and earth history, this book is a worthwhile documentation of the opinions of four very different scientists."-G. Ledyard Stebbins, BioScience "Beginning with a tracing of the universe back to its beginnings, this fascinating little book presents the current state of knowledge and recent theories relating to the origins of the universe, our earth and life on earth. The last chapter explores extinction in our geologic past. Written by distinguished scientists, all papers attempt to establish patterns that may characterize other planets as well as our own."-New Technical Books

It has long been recognized that plants and animals profoundly affect one another's characteristics during the course of evolution. However, the importance of coevolution as a dynamic process involving such diverse factors as chemical communication, population structure and dynamics, energetics, and the evolution, structure, and functioning of ecosystems has been widely recognized for a comparatively short time. Coevolution represents a point of view about the structure of nature that only began to be fully explored in the late twentieth century. The papers presented here herald its emergence as an important and promising field of biological research. Coevolution of Animals and Plants is the first book to focus on the dynamic aspects of animal-plant coevolution. It covers, as broadly as possible, all the ways in which plants interact with animals. Thus, it includes discussions of leaf-feeding animals and their impact on plant evolution as well as of predator-prey relationships involving the seeds of angiosperms. Several papers deal with the most familiar aspect of mutualistic plant-animal interactions-pollination relationships. The interactions of orchids and bees, ants and plants, and butterflies and plants are discussed. One article provides a fascinating example of more indirect relationships centered around the role of carotenoids, which are produced by plants but play a fundamental part in the visual systems of both plants and animals. Coevolution of Animals and Plants provides a general conceptual framework for studies on animal-plant interaction. The papers are written from a theoretical, rather than a speculative, standpoint, stressing patterns that can be applied in a broader sense to relationships within ecosystems. Contributors to the volume include Paul Feeny, Miriam Rothschild, Christopher Smith, Brian Hocking, Lawrence Gilbert, Calaway Dodson, Herbert Baker, Bernd Heinrich, Doyle McKey, and Gordon Frankie.

How can environmental degradation be stopped? How can it be reversed? And how can the damage already done be repaired? The authors of this volume argue that a two-pronged approach is needed: reducing demand for ecosystem goods and services and better management of them, coupled with an increase in supply through environmental restoration."Restoring Natural Capital" brings together economists and ecologists, theoreticians, practitioners, policy makers, and scientists from the developed and developing worlds to consider the costs and benefits of repairing ecosystem goods and services in natural and socioecological systems. It examines the business and practice of restoring natural capital, and seeks to establish common ground between economists and ecologists with respect to the restoration of degraded ecosystems and landscapes and the still broader task of restoring natural capital. The book focuses on developing strategies that can achieve the best outcomes in the shortest amount of time as it: considers conceptual and theoretical issues from both an economic and ecological perspective examines specific strategies to foster the restoration of natural capital and offers a synthesis and a vision of the way forwardNineteen case studies from around the world illustrate challenges and achievements in setting targets, refining approaches to finding and implementing restoration projects, and using restoration of natural capital as an economic opportunity. Throughout, contributors make the case that the restoration of natural capital requires close collaboration among scientists from across disciplines as well as local people, and when successfully executed represents a practical, realistic, and essential tool for achieving lasting sustainable development."

More than eighty years ago, before we knew much about the structure of cells, Russian botanist Boris Kozo-Polyansky brilliantly outlined the concept of symbiogenesis, the symbiotic origin of cells with nuclei. It was a half-century later, only when experimental approaches that Kozo-Polyansky lacked were applied to his hypotheses, that scientists began to accept his view that symbiogenesis could be united with Darwin's concept of natural selection to explain the evolution of life. After decades of neglect, ridicule, and intellectual abuse, Kozo-Polyansky's ideas are now endorsed by virtually all biologists.

Kozo-Polyansky's seminal work is presented here for the first time in an outstanding annotated translation, updated with commentaries, references, and modern micrographs of symbiotic phenomena.

Faced with widespread and devastating loss of biodiversity in wild habitats, scientists have developed innovative strategies for studying and protecting targeted plant and animal species in "off-site" facilities such as botanic gardens and zoos. Such ex situ work is an increasingly important component of conservation and restoration efforts.
Ex Situ Plant Conservation, edited by Edward O. Guerrant Jr., Kayri Havens, and Mike Maunder, is the first book to address integrated plant conservation strategies and to examine the scientific, technical, and strategic bases of the ex situ approach. The book examines where and how ex situ investment can best support in situ conservation. Ex Situ Plant Conservation outlines the role, value, and limits of ex situ conservation as well as updating best management practices for the field, and is an invaluable resource for plant conservation practitioners at botanic gardens, zoos, and other conservation organizations; students and faculty in conservation biology and related fields; managers of protected areas and other public and private lands; and policymakers and members of the international community concerned with species conservation.
