Now expanded and updated: Californians’ favorite reference book to trees in our everyday lives. “Anyone who is curious about trees is sure to find education and inspiration in these pages.”—David Allen Sibley, author of The Sibley Guide to Trees and The Sibley Guide to Birds For more than ten years, A Californian’s Guide to the Trees among Us has taught Californians the what, why, and how of trees in our cities and towns. This edition has been updated by the author to reflect new trends in urban forestry, with a revised introduction, updated taxonomy and nomenclature, and more than ten additional species featured. Matt Ritter introduces us to over 160 of California’s most commonly grown urban trees in this expanded edition of his best-selling book. Whether native or cultivated, these are the trees that muffle noise, create wildlife habitats, mitigate pollution, conserve energy, and make urban living healthier and more peaceful. Used as a field guide or read with pleasure for the liveliness of the prose, this book will allow readers to learn the stories behind the trees that shade our parks, grace our yards, and line our streets. Rich in photographs and illustrations, overflowing with anecdote and information, A Californian’s Guide to the Trees among Us opens our eyes to a world of beauty just outside our front doors.

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.

The complete-and-ready reference for establishing, managing, and running a successful and sustainable, profitable public garden As unique museums with living collections of plants, public gardens offer visitors aesthetically beautiful landscapes combined with educational programming and scientific research that promote the value and understanding of plants. In the twenty-first century, public gardens are in the forefront of organizations and institutions committed to promoting the conservation of plants and their habitats, developing sustainable practices that support the environment, and providing green spaces where our increasingly stressed and urbanized citizens can reconnect with the natural world. It is critically important that such institutions have trained, knowledgeable staff members. Because of its comprehensive examination of public gardens, Public Garden Management is the ideal guide for staff members at public gardens, anyone considering a career in public gardens, groups starting a botanical garden or arboretum, and students discovering how these complex institutions work. Public Garden Management is an all-in-one professional reference and textbook that clearly shows how to develop, establish, manage, and maintain a sustainable—both economically and environmentally—public garden. Offering practical coverage of relevant topics, along with useful tools for reinforcing study, this insightful and forward-thinking guide is: Copublished by the American Public Gardens Association Written by a panel of leading experts in the field Filled with dozens of case studies that are real-world illustrations of the principles explored in the text Illustrated throughout with line drawings, figures, and photographs that assist in conveying critical information Students and professionals will benefit greatly from the management principles outlined in this book, helping them establish and maintain new and existing public gardens that engage, inspire, and connect with their communities.

The late Navjot Sodhi conceived this book as a way of bringing to the forefront of our conservation planning for the tropics the views of people who were actually working and living there. In its 31 chapters, 55 authors present their views on the conservation problems they face and how they deal with them. Effective long term conservation in the tropics requires the full participation of local people, organizations and governments. The human population of tropical countries is expected to grow by more than 2.5 billion people over the next several decades, with expectations of increased consumption levels growing even more rapidly than population levels; clearly there will be a need for more trained conservationists and biologists. Significant levels of local involvement are essential to conservation success, with the rights of local people fully recognized, protected and fostered by governmental and international assistance. Overarching conservation plans are necessary, but cannot in themselves lead to success. The individual experiences presented in the pages of this book will provide useful models that may serve to build better and more sustainable lives for the people who live in the tropics and lead to the continued survival of as many species and functioning ecosystems as possible.

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.
