Book Description
The treetops of the world's forests are where discovery and opportunity abound, however they have been relatively inaccessible until recently. This book represents an authoritative synthesis of data, anecdotes, case studies, observations, and recommendations from researchers and educators who have risked life and limb in their advocacy of the High Frontier. With innovative rope techniques, cranes, walkways, dirigibles, and towers, they finally gained access to the rich biodiversity that lives far above the forest floor and the emerging science of canopy ecology. In this new edition of Forest Canopies, nearly 60 scientists and educators from around the world look at the biodiversity, ecology, evolution, and conservation of forest canopy ecosystems. Comprehensive literature list State-of-the-art results and data sets from current field work Foremost scientists in the field of canopy ecology Expanded collaboration of researchers and international projects User-friendly format with sidebars and case studies Keywords and outlines for each chapter

Book Description
Before 1910 the American chestnut was one of the most common trees in the eastern United States. Although historical evidence suggests the natural distribution of the American chestnut extended across more than four hundred thousand square miles of territory—an area stretching from eastern Maine to southeast Louisiana—stands of the trees could also be found in parts of Wisconsin, Michigan, Washington State, and Oregon. An important natural resource, chestnut wood was preferred for woodworking, fencing, and building construction, as it was rot resistant and straight grained. The hearty and delicious nuts also fed wildlife, people, and livestock. Ironically, the tree that most piqued the emotions of nineteenth- and early twentieth-century Americans has virtually disappeared from the eastern United States. After a blight fungus was introduced into the United States during the late nineteenth century, the American chestnut became functionally extinct. Although the virtual eradication of the species caused one of the greatest ecological catastrophes since the last ice age, considerable folklore about the American chestnut remains. Some of the tree’s history dates to the very founding of our country, making the story of the American chestnut an integral part of American cultural and environmental history. The American Chestnut tells the story of the American chestnut from Native American prehistory through the Civil War and the Great Depression. Davis documents the tree’s impact on nineteenth-and early twentieth-century American life, including the decorative and culinary arts. While he pays much attention to the importation of chestnut blight and the tree’s decline as a dominant species, the author also evaluates efforts to restore the American chestnut to its former place in the eastern deciduous forest, including modern attempts to genetically modify the species.

Book Description
Tropical climates, which occur between 23°30'N and S latitude (Jacob 1988), encompass a wide variety of plant communities (Hartshorn 1983, 1988), many of which are diverse in their woody floras. Within this geographic region, temperature and the amount and seasonality of rainfall define habitat types (UNESCO 1978). The F AO has estimated that there 1 are about 19 million km of potentially forested area in the global tropics, of which 58% were estimated to still be in closed forest in the mid-1970s (Sommers 1976; UNESCO 1978). Of this potentially forested region, 42% is categorized as dry forest lifezone, 33% is tropical moist forest, and 25% is wet or rain forest (Lugo 1988). The species diversity of these tropical habitats is very high. Raven (1976, in Mooney 1988) estimated that 65% of the 250,000 or more plant species of the earth are found in tropical regions. Of this floristic assemblage, a large fraction are woody species. In the well-collected tropical moist forest of Barro Colorado Island, Panama, 39. 7% (481 of 1212 species) of the native phanerogams are woody, arborescent species (Croat 1978). Another 21. 9% are woody vines and lianas. Southeast Asian Dipterocarp forests may contain 120-200 species of trees per hectare (Whitmore 1984), and recent surveys in upper Amazonia re corded from 89 to 283 woody species ~ 10 cm dbh per hectare (Gentry 1988). Tropical communities thus represent a global woody flora of significant scope.

Book Description
A revised and updated edition of a classic book that defines the field of historical ecology People and the Land through Time, first published in 1997, remains the only introduction to the field of historical ecology from the perspective of ecology and ecosystem processes. Widely praised for its emphasis on the integration of historical information into scientific analyses, it will be useful to an interdisciplinary audience of students and professionals in ecology, conservation, history, archaeology, geography, and anthropology. This up-to-date second edition addresses current issues in historical ecology such as the proposed geological epoch, the Anthropocene; historical species dispersal and extinction; the impacts of past climatic fluctuations; and trends in sustainability and conservation.
