Biodiversity, Ecosystems, and Conservation in Northern Mexico

This book describes the biodiversity and biogeography of nothern Mexico, documents the biological importance of regional ecosystems and the impacts of human land use on the conservation status of plants and wildlife. It should become the standard source document for the conservation status of species and ecosystems in this region, which is of unusual biological interest because of its high biodiversity and highly varied landscape and biological zonation.

Land of Chamise and Pines

In marked contrast to California's landscape of urban sprawl, expansive agriculture, and wildlands altered by protectionist management systems, many landscapes in neighboring Baja California would still be recognizable to the first European explorers. This book shows that the vegetation of present-day Baja California is remarkably similar to that observed in the 18th and 19th centuries, and that historical fire and grazing management has done little to alter the region's resilient mediterranean-type shrublands and forests.

Both Sides of the Border

The Mexican -- United States border represents much more than the meeting place of two nations. Our border communities are often a line of first defense -- absorbing the complex economic, environmental and social impacts of globalization that ripple through the region. In many ways, our success or failure in finding solutions for the environmental, social and economic issues that plague the region may well define our ability to meet similar challenges thousands of miles from the border zone. Border residents face the environmental security concerns posed by water scarcity and transboundary air pollution; the planning and infrastructure needs of an exploding population; the debilitating effec...

Systematics and Geographic Distribution of the American Strawberry Species

In this detailed investigation of the natural variation, geographical distribution, and modern taxonomy of the American Fragaria strawberry species, three species with four subspecies each and two hybrid species are recognized taxonomically. The author also discusses the phylogenetic relationships of the diploid and octoploid species and subspecies and their postpleistocene migration. The American octoploid Fragaria species are known as the ancestors of the large-fruited garden strawberries, so this study is of great horticultural interest and may contribute to the preservation of these species and their further use in strawberry breeding.

California’s Fading Wildflowers

Early Spanish explorers in the late eighteenth century found springtime California covered with spectacular carpets of wildflowers from San Francisco to San Diego. Yet today, invading plant species have devastated this nearly forgotten botanical heritage. In this lively, vividly detailed work, Richard A. Minnich synthesizes a unique and wide-ranging array of sources—from the historic accounts of those early explorers to the writings of early American botanists in the nineteenth century, newspaper accounts in the twentieth century, and modern ecological theory—to give the most comprehensive historical analysis available of the dramatic transformation of California's wildflower prairies. A...

Wildland fires are one of the most devastating and terrifying forces of nature. While their effects are mostly destructive they also help with regeneration of forests and other ecosystems. Low-intensity fires clear accumulating biomass reducing risk of catastrophic crown fires and can be used as an effective management tool. This book presents current understanding of wildland fires and air quality as well as their effects on human health, forests and other ecosystems. in the first section of the book the basics of wildland fires and resulting emissions are presented from the perspective of changing global climate, air quality impairment and effects on environmental and human health and secu...

Historical Ecology and Archaeology in the Galápagos Islands

The Galápagos Islands are one of the world’s premiere nature attractions, home to unique ecosystems widely thought to be untouched and pristine. Historical Ecology and Archaeology in the Galápagos Islands reveals that the archipelago is not as isolated as many imagine, examining how centuries of human occupation have transformed its landscape. This book shows that the island chain has been a part of global networks since its discovery in 1535 and traces the changes caused by human colonization. Central to this history is the sugar plantation Hacienda El Progreso on San Cristóbal Island. Here, zooarchaeological and archaeobotanical evidence documents the introduction of exotic species and landscape transformations, and material evidence attests that inhabitants maintained connections to the outside world for consumer goods. Beyond illuminating the human history of the islands, the authors also look at the impact of visitors to Galápagos National Park today, raising questions about tourism’s role in biological conservation, preservation, and restoration. A volume in the series Society and Ecology in Island and Coastal Archaeology, edited by Victor D. Thompson

Pyrocene Park

Its monumental rocks, etched by glaciers during the last Ice Age, have made Yosemite National Park a crown jewel of the national park system and a world-celebrated destination. Yet, more and more, fire rather than ice is shaping this storied landscape. In the last decade, fire has blasted into public attention. California’s blazes have captured national and global media interest with their drama and urgency. Expand the realm of fire to include the burning of fossil fuels, and the fire story also subsumes climate change. Renowned fire historian Stephen J. Pyne argues that the relationship between fire and humans has become a defining feature of our epoch, and he reveals how Yosemite offers ...
