Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Gaseous Air Pollutants and Plant Metabolism written by M. J. Kozioł and published by Butterworth-Heinemann. This book was released on 2016-03-05 with total page 481 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gaseous Air Pollutants and Plant Metabolism mainly talks about plants and air pollution. The publication of this book is inspired by a symposium on plants and pollution, which generated great interest among the personnel related to the field. The book begins with a brief background on air pollution and continues with a discussion on different types, effects, and solutions to the pollution. The book also features studies about the gaseous air pollution in North America, China, and Japan. The chapters that follow explore the different effects of pollution on chloroplasts, respiration, biochemistry, plant, and plant cells. The text is a valuable reference to undergraduates or postgraduates of chemistry and its related studies.

This book was released on 2013-04-17 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: Holm oak (Quercus ilex L.) forests and woodlands have been considered as a paradigm for Mediterranean terrestrial ecosystems. In the western part of the Mediterranean Basin, these forests and woodlands occupy large areas and thus play a very important role in the landscape. A number of research projects from the Centre d'Ecologie Fonctionnelle et Evolutive (CEFE), the Centre de Recerca Ecológica i Aplicacions Forestals (CREAF), and from many other laboratories are currently focusing on Q. ilex ecosystems, and a number of problems have appeared concerning not only basic knowledge but also management aspects. For this reason, the CEFE and the CREAF decided to jointly organize the workshop on Quercus ilex L. Ecosystems, which was held in Montpellier and Barcelona in September 1990. The present volume consists of a selection of papers presented during the workshop and other papers contributed after the workshop. The papers are divided into five sections: Biogeography and History; Structure, Productivity and Dynamics; Water Relationships; Nutrient Cycling; and Management.
