The Monteverde Cloud Forest Reserve has captured the worldwide attention of biologists, conservationists, and ecologists and has been the setting for extensive investigation over the past 30 years. Roughly 40,000 ecotourists visit the Cloud Forest each year, and it is often considered the archetypal high-altitude rain forest.This volume brings together some of the most prominent researchers of the region to provide a broad introduction to the biology of the Monteverde, and cloud forests in general. Collecting and synthesizing vital information about the ecosystem and its biota, the book also examines the positive and negative effects of human activity on both the forest and the surrounding communities. Ecologists, tropical biologists, and natural historians will find this volume an indispensable resource, as will all those who are fascinated by the magnificent wonders of the tropical forests.

This book traces the cultural development of the prehistoric Native American cultures of the Delmarva Peninsula from 12,000 B.C. to A.D. 1600, when the arrival of Europeans ended their distinctive way of life. It presents what the archaeological record reveals about human adaptation during this period in response to environmental and climatic changes.

Hurricane- and coastal-storm-related losses have increased substantially during the past century, largely due to increases in population and development in the most susceptible coastal areas. Climate change poses additional threats to coastal communities from sea level rise and possible increases in strength of the largest hurricanes. Several large cities in the United States have extensive assets at risk to coastal storms, along with countless smaller cities and developed areas. The devastation from Superstorm Sandy has heightened the nation's awareness of these vulnerabilities. What can we do to better prepare for and respond to the increasing risks of loss? Reducing Coastal Risk on the East and Gulf Coasts reviews the coastal risk-reduction strategies and levels of protection that have been used along the United States East and Gulf Coasts to reduce the impacts of coastal flooding associated with storm surges. This report evaluates their effectiveness in terms of economic return, protection of life safety, and minimization of environmental effects. According to this report, the vast majority of the funding for coastal risk-related issues is provided only after a disaster occurs. This report calls for the development of a national vision for coastal risk management that includes a long-term view, regional solutions, and recognition of the full array of economic, social, environmental, and life-safety benefits that come from risk reduction efforts. To support this vision, Reducing Coastal Risk states that a national coastal risk assessment is needed to identify those areas with the greatest risks that are high priorities for risk reduction efforts. The report discusses the implications of expanding the extent and levels of coastal storm surge protection in terms of operation and maintenance costs and the availability of resources. Reducing Coastal Risk recommends that benefit-cost analysis, constrained by acceptable risk criteria and other important environmental and social factors, be used as a framework for evaluating national investments in coastal risk reduction. The recommendations of this report will assist engineers, planners and policy makers at national, regional, state, and local levels to move from a nation that is primarily reactive to coastal disasters to one that invests wisely in coastal risk reduction and builds resilience among coastal communities.

Though seasonally dry tropical forests are equally as important to global biodiversity as tropical rainforests, and are one of the most representative and highly endangered ecosystems in Latin America, knowledge about them remains limited because of the relative paucity of attention paid to them by scientists and researchers and a lack of published information on the subject. Seasonally Dry Tropical Forests seeks to address this shortcoming by bringing together a range of experts in diverse fields including biology, ecology, biogeography, and biogeochemistry, to review, synthesize, and explain the current state of our collective knowledge on the ecology and conservation of seasonally dry tropical forests. The book offers a synthetic and cross-disciplinary review of recent work with an expansive scope, including sections on distribution, diversity, ecosystem function, and human impacts. Throughout, contributors emphasize conservation issues, particularly emerging threats and promising solutions, with key chapters on climate change, fragmentation, restoration, ecosystem services, and sustainable use. Seasonally dry tropical forests are extremely rich in biodiversity, and are seriously threatened. They represent scientific terrain that is poorly explored, and there is an urgent need for increased understanding of the system's basic ecology. Seasonally Dry Tropical Forests represents an important step in bringing together the most current scientific information about this vital ecosystem and disseminating it to the scientific and conservation communities.

The White-Inyo Range--rising sharply from the eastern edge of Owens Valley--is one of the most extraordinary landscapes in the world. High, dry, and amazingly diverse, it boasts an expansive alpine tundra and features the oldest living species on earth--the 4,000-year-old Bristlecone Pines. This colorful and authoritative volume assembles a wealth of information of deep interest to the hikers and scientists attracted to White-Inyo's altitude and isolation. The nearly two dozen contributors to the volume are leading experts on the flora and fauna, the geology, geomorphology, meteorology, anthropology, and archaeology of the area. The book offers descriptions of more than 650 kinds of living organisms, from the handful of fish to the abundance of reptile, amphibian, bird and plant species. (It provides descriptions of hundreds of flowering plants.) It contains an 8-color geologic map and a roadside guide that enables the visitor to make sense of the area's complex geological history. Readers will also learn about air currents that make the range a delight for sailplane pilots and create strange cloud formations. And a special chapter tells what is known of the Native Americans who moved up and down the mountain slopes in response to seasonal changes. For anyone who wishes to visit this astonishing area or to do research there, this volume will be a unique, comprehensive resource.
