Book Description
This book is a unique and integrated account of the history of North American vegetation and paleoenvironments over the past 70 million years. It includes discussions of the modern plant communities, causal factors for environmental change, biotic response, and methodologies. The history reveals a North American vegetation that is vast, immensely complex, and dynamic.

Book Description
"This completely new edition of Terrestrial Vegetation of California clearly documents the extraordinary complexity and richness of the plant communities and of the state and the forces that shape them. This volume is a storehouse of information of value to anyone concerned with meeting the challenge of understanding, managing or conserving these unique plant communities under the growing threats of climate change, biological invasions and development."—Harold Mooney, Professor of Environmental Biology, Stanford University "The plants of California are under threat like never before. Traditional pressures of development and invasive species have been joined by a newly-recognized threat: human-caused climate change. It is essential that we thoroughly understand current plant community dynamics in order to have a hope of conserving them. This book represents an important, well-timed advance in knowledge of the vegetation of this diverse state and is an essential resource for professionals, students, and the general public alike."—Brent Mishler, Director of the University & Jepson Herbaria and Professor of Integrative Biology, University of California, Berkeley

Book Description
Illustrative examples from recent research publications and "classic" studies are prominently featured throughout the book. Research techniques are highlighted in "special interest" boxes. Illustrations and descriptions of research techniques are provided with examples such as fire-scars from trees used to reconstruct disturbance, fossil pollen used to reconstruct vegetation change and plant migration, transect and quadrate sampling. Includes key biogeographical theories that link space and time to the distribution of life. Some of these theories include: 1. Ranges, Reflicts, Refuges, Corridors, Barriers, 2. Centers of Origins, 3. Cladistics, 4. Variance, 5. Island BioGeography, 6. Diversity Theory, 7. Gap Analysis for Conservation.

Book Description
Thorough, detailed dendrological coverage of North American trees, shrubs, and vines This comprehensive field guide/procedural handbook provides extraordinarily detailed descriptions of trees, shrubs, and vines of North American forests. Written at a more detailed level than most field guides, it introduces basic taxonomic concepts and methods and explains the rationale behind taxonomic classification systems. Entries include Latin and common names for each species as well as physical descriptions at various levels of maturity and for different seasons. Also noted are regional and state distributions, soil conditions, cover types, shade tolerances, and common diseases and pests. This remarkably thorough and reliable reference includes: * Detailed descriptions of more than 800 species * Hundreds of additional varieties and cultivars * 550 exquisitely detailed line drawings of leaves, bark, fruit, and seeds * Broad coverage of commercial and noncommercial species * An emphasis on the silvical features of each species * A unique section on forest community ecology and cover types * The new North American Classification System Well-organized and practical, this authoritative guide is an immensely useful resource for foresters, wildlife and field biologists, naturalists, environmental scientists, and land managers.

Book Description
In North America, Juniperus woodlands occupy approximately 55 million hectares, an area larger than the state of Texas. This title addresses various aspects of the biology, ecology, and management of Juniperus woodlands and savannas, synthesizing past and current research findings as well as proposed research. The book provides ecologists, land managers, and foresters with a solid foundation in Juniperus ecosystems, enabling them to manage the communities for maximum sustained productivity and diversity.

Book Description
This book begins with the physical and biological characterization of the four North American deserts and a description of the primary adaptations of plants to environmental stress. In the following chapters the authors present case studies of key species representing dominant growth forms of the North American deserts, and provide an up-to-date and comprehensive review of the major patterns of adaptations in desert plants. One chapter is devoted to several important exotic plants that have invaded North American deserts. The book ends with a synthesis of the adaptations and resource requirements of North American desert plants. Further, it addresses how desert plants may respond to global climate change.

Book Description
Together with experts in a variety of disciplines in the natural and social sciences--including botany, geology, ecology, geography and archaeology--Lentz investigates the history and effects of human impact on the environment in the New World before the arrival of the Europeans in the late 15th century. An Imperfect Balance offers an objective evaluation of "precontact era" land usage, demonstrating that native populations engaged in land management practices not entirely dissimilar to their European counterparts.

Book Description
This fourth volume in the new multi-volume set Global Biodiversity is a rich resource on the biodiversity of a selection of countries in the Americas and in Australia. Chapters explore both wild and cultivated plants, wild and domesticated animals, and the variety of microbes of the countries of Bolivia, Brazil, Canada, Costa Rica, Cuba, Ecuador, Honduras, Mexico, Australia, Paraguay, the United States, and Venezuela. The different chapters explore the geographical status, ecosystem diversity, species diversity, genetic diversity, and conservation efforts in each selected country. They focus on genetic diversity of crop plants/cultivated plants and domesticated animals and their wild relatives and also discuss the endangered and protected plants and animals of the respective counties. Other volumes in this series include coverage of selected countries in Asia, Europe, and Africa. The volumes provide an informative compilation on the variety and variability of life in the regions discussed and will help to fill the gap in knowledge while also encouraging the conservation of biodiversity and sustainable utilization.

Book Description
The book provides information essential for anyone interested in the ecology of the American Southwest, including land managers, environmental planners, conservationists, ecologists and students. It is unique in its coverage of the hows and whys of dynamics (changes) in the major types of vegetation occurring on southwestern mountains and plateaus. It explains the drivers and processes of change, describes historical changes and provides conceptual models that diagrammatically illustrate past, present, and potential future changes. All major types of vegetation are covered: spruce-fir, mixed conifer, and ponderosa pine forests, pinyon-juniper vegetation, subalpine-montane grassland, and Gambel oak and interior chaparral shrublands. The focus is on vegetation that is relatively undisturbed, i.e., in natural and near-natural condition, and how it responds to natural disturbances such as fire and drought, as well as to anthropogenic disturbances such as fire exclusion and invasive species
