Until relatively recently the valuable tropical montane cloud forests (hereaf ter usually referred to as TMCFs) of the world had scarcely come under the assaults experienced by the downslope montane and lowland forests. TMCFs are not hospitable environments for human occupation, and their remoteness (except in places near Andean high mountain settlements and in the Ethiopian Highlands) and difficult terrain have given them de facto protection. The ad jacent upper montane rain forests have indeed been under assault for timber, fuelwood, and for conversion to grazing and agriculture for many decades, even centuries in the Andes, but true cloud forest has only come under ex ploitation as these lower elevational resources have disappeared. They have also been "nibbled" at from above where there have been alpine grasslands under grazing pressure. Increasingly now, however, these cloud forest eco systems are being fragmented, reduced, and disturbed at an alarming rate. It is now becoming recognized that steps must be taken rapidly to increase our understanding of TMCF and to achieve their conservation, because: their water-capture function is extremely important to society; • their species endemism is high; they serve as refugia for endangered species being marginalized in these environments by increasingly transformed lower elevation ecosystems; they are relatively little studied; yet, their value to science is extremely high; they have low resilience to disturbance; vii viii Preface and many other reasons, which will be discussed subsequently in this publi cation.

This book presents an evolutionary biogeographic analysis of the Mexican Transition Zone, which is situated in the overlap of the Nearctic and Neotropical regions. It includes a comprehensive review of previous track, cladistic and molecular biogeographic analyses and is illustrated with full color maps and vegetation photographs of the respective areas covered. Given its scope, the book will be of interest to students and researchers whose work involves systematic and biogeographic analyses of plant and animal taxa of the Mexican Transition Zone or other transition zones of the world, and to ecologists working in biodiversity conservation, who will be able to appreciate the evolutionary relevance of the Mexican Transition Zone for establishing conservation areas..

Dendroecologists apply the principles and methods of tree-ring science to address ecological questions and resolve problems related to global environmental change. In this fast-growing field, tree rings are used to investigate forest development and succession, disturbance regimes, ecotone and treeline dynamics and forest decline. This book of global scope highlights state-of-the-science dendroecological contributions to paradigm-shifts in our understanding of ecophysiology, stand dynamics, disturbance interactions, forest decline and ecosystem resilience to global environmental change and is fundamental to better managing our forested ecosystems for the full range of ecosystem goods and services that they provide.

Since 1978, when the World Bank published its policy paper on forestry, the world's understanding of and concern about the forest sector of the developing world has increased substantially. It has become clear that forests and woodlands play an even more important economic and ecological role than had earlier been recognized. In particular, the importance of tropical moist forests in protecting biological diversity has become more fully appreciated, as has their role in the carbon cycle and in global climatic change.

Mexican conservationists have sometimes observed that it is difficult to find a country less interested in the conservation of its natural resources than is Mexico. Yet, despite a long history dedicated to the pursuit of development regardless of its environmental consequences, Mexico has an equally long, though much less developed and appreciated, tradition of environmental conservation. Lane Simonian here offers the first panoramic history of conservation in Mexico from pre-contact times to the current Mexican environmental movement. He explores the origins of conservation and environmental concerns in Mexico, the philosophies and endeavors of Mexican conservationists, and the enactment of important conservation laws and programs. This heretofore untold story, drawn from interviews with leading Mexican conservationists as well as archival research, will be important reading throughout the international community of activists, researchers, and concerned citizens interested in the intertwined issues of conservation and development.

It is represented by 49 species, which grow primarily as epiphytes in tropical forests at high elevations. / II. Melpomene - systematic revision. Twenty-nine neotropical species and 10 varieties are recognized. Occurring at 400-5200m elevation in varied habitats, distribution is Mesoamerica, the Caribbean, and tropical South America, with one disjunction to Africa, Madagascar, and the Mascarenes. / III. Alansmia - taxonomic monograph. Twenty-five species and 2 varieties of this primarily neotropical, epiphytic genus are presented. Occurrence is predominantly in montane forests but also lowland forests and páramos.

A Companion to Environmental Geography is the first book to comprehensively and systematically map the research frontier of 'human-environment geography' in an accessible and comprehensive way. Cross-cuts several areas of a discipline which has traditionally been seen as divided; presenting work by human and physical geographers in the same volume Presents both the current 'state of the art' research and charts future possibilities for the discipline Extends the term 'environmental geography' beyond its 'traditional' meanings to include new work on nature and environment by human and physical geographers - not just hazards, resources, and conservation geographers Contains essays from an outstanding group of international contributors from among established scholars and rising stars in geography

The Río Mayo region of northwestern Mexico is a major geographic area whose natural history remains poorly known to outsiders. Lying in a region where desert and tropical, northern and southern, and continental and coastal species converge, it boasts an abundance of flora first documented by Howard Scott Gentry in 1942 in a book now widely regarded as a classic of botanical literature. This new book updates and amends Gentry's Río Mayo Plants. Undertaken with Gentry's support and participation before his death in 1993, it reproduces the original text, which appears here with annotations, and contains information on over 2,800 taxa—more than twice the 1,200 species first described by Gentry. The annotated list of plants includes information on distribution, habitat, appearance, common names, and indigenous uses. A new introduction provides historical background and a review of geography and vegetation. It also describes changes to the land and river wrought by agricultural development, expanded grazing, and lumbering. Throughout the text, the authors have endeavored to provide information on Río Mayo vegetation while emphasizing local knowledge and use of plants, to preserve Gentry's field-oriented focus, and to present botanical information with Gentry's exuberance and style. Río Mayo Plants has long stood as a book that displays a scientist's love of the English language, his fondness for native peoples, and his eye for beauty in nature. This updating of that work fills a gap in the botanical literature of this portion of North America and will be useful not only for botanists but also for biogeographers, taxonomists, land managers, and conservationists.
