Book Description
A few conifers are found in nature only in narrow, discontinuous bands bordering continental margins. Despite their maritime location, these trees cannot thrive in saline waters and soils. What enables them to grow in challenging habitats? Why don't these species naturalize inland? What characteristics allow them to succeed only near salt water? A strange combination of qualities is seen: the trees are catastrophe-dependent, stress-tolerant, with broad niche potential, but are poor competitors in "easy" sites. They all possess moisture-conserving features usually associated with arid lands, although they grow in regions of high humidity and frequent fogs. This volume is the first to assemble and compare information on widely dispersed coastal forests of the Northern Hemisphere. Authorities on each system explore the properties of these unusual trees and their habitats, and formulate guidelines for their appropriate management and protection. The thirty-six contributing authors include natural resource managers and regulators, ecologists, lumbermen, geneticists, botanists, and paleontologists. The book draws from work on three continents, eight countries, and twenty-three states of the Unites States. One half of the volume is devoted to the seven highly prized, commercially valuable Chamaecyparis species.

Book Description
This thoroughly revised, entirely rewritten edition of what is the essential reference on California’s diverse and ever-changing vegetation now brings readers the most authoritative, state-of-the-art view of California’s plant ecosystems available. Integrating decades of research, leading community ecologists and field botanists describe and classify California’s vegetation types, identify environmental factors that determine the distribution of vegetation types, analyze the role of disturbance regimes in vegetation dynamics, chronicle change due to human activities, identify conservation issues, describe restoration strategies, and prioritize directions for new research. Several new chapters address statewide issues such as the historic appearance and impact of introduced and invasive plants, the soils of California, and more.

Book Description
One of the most recognizable animals of the Southwest, the desert tortoise (Gopherus agassizii) makes its home in both the Sonoran and Mohave Deserts, as well as in tropical areas to the south in Mexico. Called by Tohono O'odham people "komik'c-ed," or "shell with living thing inside," it is one of the few desert creatures kept as a domestic pet—as well as one of the most studied reptiles in the world. Most of our knowledge of desert tortoises comes from studies of Mohave Desert populations in California and Nevada. However, the ecology, physiology, and behavior of these northern populations are quite different from those of their southern, Sonoran Desert, and tropical cousins, which have been studied much less. Differences in climate and habitat have shaped the evolution of three races of desert tortoises as they have adapted to changes in heat, rainfall, and sources of food and shelter as the deserts developed in the last ten million years. This book presents the first comprehensive summary of the natural history, biology, and conservation of the Sonoran and Sinaloan desert tortoises, reviewing the current state of knowledge of these creatures with appropriate comparisons to Mohave tortoises. It condenses a vast amount of information on population ecology, activity, and behavior based on decades of studying tortoise populations in Arizona and Sonora, Mexico, and also includes important material on the care and protection of tortoises. Thirty-two contributors address such topics as tortoise fossil records, DNA analysis, and the mystery of secretive hatchlings and juveniles. Tortoise health is discussed in chapters on the care of captives, and original data are presented on the diets of wild and captive tortoises, the nutrient content of plant foods, and blood parameters of healthy tortoises. Coverage of conservation issues includes husbandry methods for captive tortoises, an overview of protective measures, and an evaluation of threats to tortoises from introduced grass and wildfires. A final chapter on cultural knowledge presents stories and songs from indigenous peoples and explores their understanding of tortoises. As the only comprehensive book on the desert tortoise, this volume gathers a vast amount of information for scientists, veterinarians, and resource managers while also remaining useful to general readers who keep desert tortoises as backyard pets. It will stand as an enduring reference on this endearing creature for years to come.

Book Description
This highly readable, spectacularly illustrated compendium is an ecological journey into a wondrous land of extremes. The California Deserts explores the remarkable diversity of life in this harsh yet fragile quarter of the Golden State. In a rich narrative, it illuminates how that diversity, created by drought and heat, has evolved with climate change since the Ice Ages. Along the way, we find there is much to learn from each desert species-- whether it is a cactus, pupfish, tortoise, or bighorn sheep--about adaptation to a warming, arid world. The book tells of human adaptation as well, and is underscored by a deep appreciation for the intimate knowledge acquired by native people during their 12,000-year desert experience. In this sense, the book is a journey of rediscovery, as it reflects on the ways that knowledge has been reclaimed and amplified by new discoveries. The book also takes the measure of the ecological condition of these deserts today, presenting issues of conservation, management, and restoration. With its many sidebars, photographs, and featured topics, The California Deserts provides a unique introduction to places of remarkable and often unexpected beauty.
