Available in PDF, EPUB and Kindle. Book excerpt: The San Pedro River in southeastern Arizona not only features some of the richest wildlife habitat in the Southwest, it also is home to more kinds of animals than anywhere else in the contiguous United States. Here you'll find 82 species of mammals, dozens of different reptiles and amphibians, and nearly 400 species of birds—more than half of those recorded in the entire country. In addition, the river supports one of the largest cottonwood-willow forest canopies remaining in Arizona. It's little wonder that the San Pedro was named by the Nature Conservancy as one of the Last Great Places in the Northern Hemisphere, and by the American Bird Conservancy as its first Important Bird Area in the United States. Roseann Hanson has spent much of her life exploring the San Pedro and its environs and has written a book that is both a personal celebration of and a definitive guide to this, the last undammed and unchanneled river in the Southwest. Taking you from the San Pedro's entry into the U.S. at the Mexican border to its confluence with the Gila River about a hundred miles north, she devotes a separate chapter to each of seven sections of river. Each chapter contains an eloquent essay on natural and cultural history, laced with Hanson's own experiences, plus an exploration guide brimming with useful information: how to get to the river, finding hiking trails, camping and other accommodations, birdwatching tips, access to biking and horseback riding, and nearby historic sites. Maps are included for each stretch of river, and the text is illustrated throughout with drawings from Roseann's copious field notebooks. Along the 40 miles of the San Pedro Riparian National Conservation Area, a sanctuary protected by the Bureau of Land Management since 1988, Hanson shows how the elimination of cattle and off-road vehicles has restored the river corridor to a more natural condition. She tells of the impact of humans on the San Pedro, from Clovis hunters to American settlers to Washington bureaucrats, and shows how, as the river winds its way north, it is increasingly threatened by groundwater pumping and urbanization. In addition to the "discovery" sections of each chapter, Hanson has included species checklists for habitats and plants, birds, mammals, and reptiles and amphibians to make this a perfect companion for anyone exploring the area, whether as occasional tourist or frequent visitor. The book's blending of graceful prose and practical information shows that a river is the sum of many parts. Roseann Hanson will give you a special understanding—and perhaps a sense of stewardship—of this wild place.

Available in PDF, EPUB and Kindle. Book excerpt: The Clean Water Act (CWA) requires that wetlands be protected from degradation because of their important ecological functions including maintenance of high water quality and provision of fish and wildlife habitat. However, this protection generally does not encompass riparian areasâ€"the lands bordering rivers and lakesâ€"even though they often provide the same functions as wetlands. Growing recognition of the similarities in wetland and riparian area functioning and the differences in their legal protection led the NRC in 1999 to undertake a study of riparian areas, which has culminated in Riparian Areas: Functioning and Strategies for Management. The report is intended to heighten awareness of riparian areas commensurate with their ecological and societal values. The primary conclusion is that, because riparian areas perform a disproportionate number of biological and physical functions on a unit area basis, restoration of riparian functions along America's waterbodies should be a national goal.

Available in PDF, EPUB and Kindle. Book excerpt: In the life sciences, there is wide-ranging debate about biodiversity. While nearly everyone is in favor of biodiversity and its conservation, methods for its assessment vary enormously. So what exactly is biodiversity? Most theoretical work on the subject assumes it has something to do with species richness—with the number of species in a particular region—but in reality, it is much more than that. Arguing that we cannot make rational decisions about what it is to be protected without knowing what biodiversity is, James Maclaurin and Kim Sterelny offer in What Is Biodiversity? a theoretical and conceptual exploration of the biological world and how diversity is valued. Here, Maclaurin and Sterelny explore not only the origins of the concept of biodiversity, but also how that concept has been shaped by ecology and more recently by conservation biology. They explain the different types of biodiversity important in evolutionary theory, developmental biology, ecology, morphology and taxonomy and conclude that biological heritage is rich in not just one biodiversity but many. Maclaurin and Sterelny also explore the case for the conservation of these biodiversities using option value theory, a tool borrowed from economics. An erudite, provocative, timely, and creative attempt to answer a fundamental question, What Is Biodiversity? will become a foundational text in the life sciences and studies thereof.

Available in PDF, EPUB and Kindle. Book excerpt: In 1502, Christopher Columbus named Costa Rica, and while gold and silver never materialized to justify the moniker of rich coast in purely economic terms, scientists and ecotravelers alike have long appreciated its incredible wealth. Wealth in Costa Rica is best measured by its biodiversityhome to a dizzying number of plants and animals, many endemic, it s a country that has long encouraged and welcomed researchers from the world over, and is exemplary in the creation and commitment to indigenous conservation and management programs. Costa Rica is considered to have the best preserved natural resources in Latin America. Approximately nine percent (about 1,000,000 acres) of Costa Rica has been protected in 15 national parks, and a comparable amount of land is protected as wildlife refuges, forest reserves or Indian reservations. This long-awaited synthesis of Costa Rican ecosystems is an authoritative presentation of the paleoecology, biogeography, structure, conservation, and sustainable use of Costa Rica s ecosystems. It systematically covers the entire range of Costa Rica s natural and managed, terrestrial, freshwater and marine ecosystems, including its island systems (Cocos Islands), the Atlantic and Pacific oceans and shores (coasts, coral reefs, mangrove forests), its lowlands (dry, season and wet forests), its highlands (the northern volcanoes and southern Talamanca s), and its estuaries, rivers, lakes, swamps and bogs. The volume s integrated, comprehensive format will be welcomed by tropical and temperate biologists alike, by biogeographers, plant and animal ecologists, marine biologists, conservation biologists, foresters, policy-makers and all scientists, natural history specialists and all with an interest in Costa Rica s ecosystems."

Book excerpt: "Poplar is increasingly recognized as an excellent model tree for the study of tree growth and its underlying physiology and genetics. By studying trees of the genus Populus (poplars, cottonwoods, aspens), which in their native ecosystems play a major role in the re-colonization of sites after disturbances, new insights have been gained into plantation culture and the development of improved cultivars. Of the 20 chapters in this publication, editored by an international group of researchers, one section deals with systematics, genetics, genetic manipulation and biotic interactions of Populus, while the other deals with stress response and the physiology of growth and productivity" --

Book excerpt: contributors - biologists, ecologists, geomorphologists, historians, hydrologists, lawyers, and political scientists - weave together threads from their diverse perspectives to reveal the processes that shape the past, present, and future of the San Pedro's riparian and aquatic ecosystems. They review the biological communities of the San Pedro and the stream hydrology and geomorphology that affects its riparian biota. They then look at conservation and management challenges along three sections of the San Pedro, from its headwaters in Mexico in its confluence with the Gila River, describing legal and policy issues and their interface with science; activities related to mitigation, conservation, and restoration; and a prognosis of the potential for sustaining the basin's riparian system." "Complemented by a foreword written by James Shuttleworth, these chapters demonstrate the complexity of the San Pedro's ecological and hydrological conditions, showing that there are no easy --

Available in PDF, EPUB and Kindle. Book excerpt: Ask airline passengers what they see as they gaze out the window, and they will describe a fragmented landscape: a patchwork of desert, woodlands, farmlands, and developed neighborhoods. Once-contiguous forests are now subdivided; tallgrass prairies that extended for thousands of miles are now crisscrossed by highways and byways. Whether the result of naturally occurring environmental changes or the product of seemingly unchecked human development, fractured lands significantly impact the planet’s biological diversity. In Ecology of Fragmented Landscapes, Sharon K. Collinge defines fragmentation, explains its various causes, and suggests ways that we can put our lands back together. Researchers have been studying the ecological effects of dismantling nature for decades. In this book, Collinge evaluates this body of research, expertly synthesizing all that is known about the ecology of fragmented landscapes. Expanding on the traditional coverage of this topic, Collinge also discusses disease ecology, restoration, conservation, and planning. Not since Richard T. T. Forman's classic Land Mosaics has there been a more comprehensive examination of landscape fragmentation. Ecology of Fragmented Landscapes is critical reading for ecologists, conservation biologists, and students alike.
