Download or read book Woody Plants Evolution and Distribution Since the Tertiary written by Deutsche Akademie der Naturforscher Leopoldina and published by Springer Science & Business Media. This book was released on 1989-03-31 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: Paleobotany has enormously expanded the documentation of fossil plant groups, floras and vegetation types, supporting its conclusions by technically much improved analyses of microfossils (pollen) and anatomical details. An increasing quantity and quality of all these informations from the geosciences is available when we follow the history of the biosphere up to the present. Simultaneously, research from the biosciences on the morphology, ecology, distribution, systematics and evolution of extant vascular plants, and on the ecogeographical differentiation of the vegetation cover of our planet, has made enormous progress. Thus, a synthetic geo- and bioscientific approach becomes more and more feasible and urgent for further advances in the many problems of common concern. A symposium organized by the "Deutsche Akademie der Naturforscher LEOPOLDINA", attractive to paleo- and neobotanists, stimulated the discussion between specialists of the two disciplines. The main results of the symposium are now presented in this volume: Sixteen international contributions outline the current knowledge about the historical differentiation and evolution of woody plant groups and forests, covering the whole biosphere. This survey, from the beginning of the Tertiary up to the present, is a first systhesis of relevant data from the geo- and biosciences.

Download or read book The Encyclopedia of Psychoactive Plants written by Christian Rätsch and published by Simon and Schuster. This book was released on 2005-04-25 with total page 3143 pages. Available in PDF, EPUB and Kindle. Book excerpt: The most comprehensive guide to the botany, history, distribution, and cultivation of all known psychoactive plants • Examines 414 psychoactive plants and related substances • Explores how using psychoactive plants in a culturally sanctioned context can produce important insights into the nature of reality • Contains 797 color photographs and 645 black-and-white illustrations In the traditions of every culture, plants have been highly valued for their nourishing, healing, and transformative properties. The most powerful plants--those known to transport the human mind into other dimensions of consciousness--have traditionally been regarded as sacred. In The Encyclopedia of Psychoactive Plants Christian Rätsch details the botany, history, distribution, cultivation, and preparation and dosage of more than 400 psychoactive plants. He discusses their ritual and medicinal usage, cultural artifacts made from these plants, and works of art that either represent or have been inspired by them. The author begins with 168 of the most well-known psychoactives--such as cannabis, datura, and papaver--then presents 133 lesser known substances as well as additional plants known as “legal highs,” plants known only from mythological contexts and literature, and plant products that include substances such as ayahuasca, incense, and soma. The text is lavishly illustrated with 797 color photographs--many of which are from the author’s extensive fieldwork around the world--showing the people, ceremonies, and art related to the ritual use of the world’s sacred psychoactives.

Available in PDF, EPUB and Kindle. Book excerpt: This dictionary will present all currently accepted generic, specific, sub-specific and variety names of trees, excluding fossil and more recently extinct taxa, hybrids and cultivars. Only the indigenous trees of a continent, those wild species that were natural elements of the spontaneous forest vegetation before the arrival of Europeans or other colonizers, are included.Each generic entry includes the family to which it is assigned, the synonyms of the Latin name, and the English, French, Spanish, trade and other names. For the English and French names the standard name is listed first, followed by other available names with, in parentheses, the countries where they are used. Where appropriate, names in additional languages are also included.Each infrageneric (species, subspecies, variety) entry includes, in addition, the distribution, height, type of foliage, ecological characteristics and main uses of the tree when available.In this volume only taxa indigenous on the North American continent are included, considered in a geographical, not in a political sense. This means from Alaska and Greenland to Panama, including Caribbean, but excluding Hawaii.

Download or read book Spider Monkeys written by Christina J. Campbell and published by Cambridge University Press. This book was released on 2008-09-25 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spider monkeys are one of the most widespread New World primate genera, ranging from southern Mexico to Bolivia. Although they are common in zoos, spider monkeys are traditionally very difficult to study in the wild, because they are fast moving, live high in the canopy and are almost always found in small subgroups that vary in size and composition throughout the day. This book is an assimilation of both published and previously unpublished research. It is a comprehensive source of information for academic researchers and graduate students interested in primatology, evolutionary anthropology and behavioral ecology and covers topics such as taxonomy, diet, sexuality and reproduction, and conservation.
