Book Description
Drawing on research from biodiversity experts around the world, this book reflects the diversity of forest types and forest issues that concern forest scientists. Coverage ranges from savannah and tropical rainforests to the ancient oak forests of Poland; issues explored include the effects of logging, management practices, forest dynamics and climate change on forest structure and biodiversity. Here is a useful overview of current science, for researchers and educators alike.

Book Description
Driven by the increasing necessity to define the biological diversity frame of widespread, endemic and threatened species, as well as by the stimulating chance to describe new species, the study of the evolutive and spatial dynamics is in constant execution. Systematic overviews, biogeographic and phylogenic backgrounds, species composition and distribution in restricted areas are focal topics of the 15 interesting independent chapters collected in this book, chosen to offer to the reader an overall view of the present condition in which our planet is.

Book Description
This volume is the twenty-ninth in this series, which includes twenty-eight numbered volumes and one unnumbered supplement. The editors continue to focus on critical reviews, commentaries, original papers, and controversies in of the reviews range from anthropology to evolutionary biology. The topics molecular evolution, population biology to paleobiology. Recent volumes have included a broad spectrum of chapters on such subjects as population biology, comparative morphology, paleobiology, molecular phy logenetics, developmental evolutionary biology, systematics, and the history of evolutionary biology. The editors continue to solicit manuscripts in all areas of evolutionary biology. Manuscripts should be sent to anyone of the following: Max K.

Book Description
Plants of the World is the first book to systematically explore every vascular plant family on earth—more than four hundred and fifty of them—organized in a modern phylogenetic order. Detailed entries for each family include descriptions, distribution, evolutionary relationships, and fascinating information on economic uses of plants and etymology of their names. All entries are also copiously illustrated in full color with more than 2,500 stunning photographs. A collaboration among three celebrated botanists at the Royal Botanic Gardens, Kew, Plants of the World is authoritative, comprehensive, and beautiful. Covering everything from ferns to angiosperms, it will be an essential resource for practicing botanists, horticulturists, and nascent green thumbs alike.

Book Description
Extending from west Africa to Madagascar, from the vast lowland Congo Basin to the archipelago of forest islands on its eastern rim, the African rain forest is surpassed in size only by the Amazon. This book sheds light on the current efforts to understand and conserve the African rain forest, an area in need of urgent action to save its biological wealth, cultural heritage, and economic potential. Written by conservation scientists and practitioners based in the African rain forest, the book offers a multidisciplinary perspective that integrates many biological and social sciences. Early chapters trace the forces--from paleoecological factors to recent human actions--that have shaped the African forest environment. The next chapters discuss the dominant biological patterns of species ranging from the distinctive elephants, gorillas, and okapi to the less well known birds, butterflies, and amphibians. Other chapters focus on how such different groups as hunter-gatherers, forest farmers, bushmeat hunters, recent immigrants, and commercial foresters have used the forests. Several authors stress the need for tighter links between research and conservation action. The final section draws lessons from the collective experience of those working in an Africa wracked by political strife and economic hardship.

Book Description
Mountain forests provide important ecological services, and essential products. This book focuses on the importance of mountain forests in Cameroon for the local people who depend most directly on them, and have often developed a wealth of indigenous knowledge on plants and sophisticated institutions for managing limited plant and animal resources. Such knowledge and institutions have often been threatened, or even destroyed, by centralization and globalization; yet there is increasing recognition that community-based institutions are the best adapted to ensuring that mountain forests continue to supply their diverse goods and services to both mountain and other people over the long-term. The book provides a useful combination of case studies on ethnobotanic analysis and cultural values of plants, community-based ecological planning for protected area management and eco-cultural tourism development. It provides an unusually useful combination of overviews and synthesis of theory and experience with in-depth case studies of montane forest-adjacent communities and protected areas. Throughout the book there are good summary tables, case study maps, and diagrams that are relevant to the themes in question. Finally, the book addresses the possible mutual benefits of indigenous knowledge and modern science, indigenous peoples and the development of eco-cultural tourism in protected areas, indigenous peoples and ecological planning in protected areas. It therefore emphasizes cooperation based on partnerships amongst indigenous people, governments and the global conservation community, in the interest of effective conservation. This is a valuable book for land managers, environmental scientists, environmental biologists, natural resource managers and students reading subjects such as geography, biology, forestry, botany and environmental science.
