Available in PDF, EPUB and Kindle. Book excerpt: "The genus Mitrephora (Annonaceae) comprises 47 species of small to medium-sized trees, growing in tropical lowland and submontane forests throughout Southeast Asia. The centers of diversity lie in Borneo, where there are 12 species, and the Philippines, where there are 11 species. The flowers are pendent and hermaphroditic, with two whorls of petals, of which the outer petals are larger. The inner petals are apically con-nivent over the productive structures, forming a partially enclosed pollination chamber with small apertures between the basal claws of the petals that enable entry by pollinators. A field study of the pollination ecology of M. heyneana in Sri Lanka (the first such study for the genus) revealed pollination by small nitidulid beetles, although it is possible that other species may be fly-pollinated. This monograph is the first comprehensive taxonomic revi-sion of the genus. The work is based on a comprehensive study of comparative morphology and anatomy, including a survey of previously published work. Conservation assessments are provided for each species, according to current IUCN Red List categories and criteria. All species are mapped and many are illustrated with line drawings and/or photographs. Separate keys for flowering and fruiting material are included, as well as regional keys. Seven new species (M. amdjahii, M. endertii, M. kostermansii, M. multifolia, M. sorsogonensis, M. sundaica, and M. uniflora) and one new combination (M. macrocarpa) are proposed"--Publisher's description.

Download or read book Tropical Forests in Transition written by J. Goldammer and published by Birkhäuser. This book was released on 2013-03-08 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: In evolutionary time scales natural disturbances have affected the vegetation on Earth. During the Quaternary the forest biomes of the tropics were subjected to manifold disturbances. Climate changes and climate oscillations were associated with changing precipitation and drought regimes, flooding, siltation, landslides, etc. The prehistorical forest was also influenced by the effects of large wildlife populations. Large-scale catastrophies in the forest biomes were mainly caused by abiotic environmental alterations, the small-scale disturbances were and still are related to both biotic and abiotic processes. Both the large-and the small-scale disturbances have played a significant role in shaping distribution, dynamics, structure and composition of the paleoforest. After the expansion of hominids and early humans, and later, by modern humans, the anthropogenic influences on the tropical forest began to overlap natural disturbances. Today's anthropogenic impacts on the tropical forests differ qualitatively and quanitatively from the natural disturbances. The speed of tropical deforestation and savannization is dramatically increasing. The physical and chemical impacts of forest conversion and biomass burning add to other anthropogenic influences on the atmosphere and climate. The expected anthropogenic climate change will also have considerable impacts on the tropical flora and fauna. The book on "Tropical Forests in Transition" synthesizes information on changing environmental conditions and human impacts on the tropical forest by looking back to the paleoecology, analyzing the impact of modern human populations and modeling the future of the tropical forest in a changing environment. The aim of the book is to strengthen multidisciplinary thinking in disturbance ecology.

Download or read book Flowering Plants written by Armen Takhtajan and published by Springer Science & Business Media. This book was released on 2009-07-06 with total page 906 pages. Available in PDF, EPUB and Kindle. Book excerpt: Armen Takhtajan is among the greatest authorities in the world on the evolution of plants. This book culminates almost sixty years of the scientist's research of the origin and classification of the flowering plants. It presents a continuation of Dr. Takhtajan’s earlier publications including “Systema Magnoliophytorum” (1987), (in Russian), and “Diversity and Classification of Flowering Plants” (1997), (in English). In his latest book, the author presents a concise and significantly revised system of plant classification (‘Takhtajan system’) based on the most recent studies in plant morphology, embryology, phytochemistry, cytology, molecular biology and palynology. Flowering plants are divided into two classes: class Magnoliopsida (or Dicotyledons) includes 8 subclasses, 126 orders, c. 440 families, almost 10,500 genera, and no less than 195,000 species; and class Liliopsida (or Monocotyledons) includes 4 subclasses, 31 orders, 120 families, more than 3,000 genera, and about 65,000 species.This book contains a detailed description of plant orders, and descriptive keys to plant families providing characteristic features of the families and their differences.

Download or read book Woody Plants of Western African Forests written by William Hawthorne and published by Royal Botanic Gardens Kew. This book was released on 2006 with total page 1046 pages. Available in PDF, EPUB and Kindle. Book excerpt: A guide to the identification of all the woody plants (c. 2,250 species in 740 genera) of the forest region of West Africa called 'Upper Guinea', between Togo and Senegal. Upper Guinea is one of the world's most important centres of biodiversity, from the mountain forests of Liberia, Guinea and Sierra Leone, to the lowland evergreen, and semideciduous forests widespread also in Ghana and Ivory Coast. This comprehensively illustrated guide will play a vital supportive role in the challenge of sustainable development within the forest region of West Africa, helping to promote best practice in the management of its plants and forests.
Download or read book Diversity and Classification of Flowering Plants written by Armen Leonovich Takhtadzhi͡an and published by Columbia University Press. This book was released on 1997 with total page 662 pages. Available in PDF, EPUB and Kindle. Book excerpt: The culmination of more than fifty years of research by the foremost living expert on plant classification, Diversity and Classification of Flowering Plants is an important contribution to the field of plant taxonomy. In the last decade, the system of classifying plants has been thoroughly revised. Instead of describing every individual family, Takhtajan includes descriptions in keys to families, which he calls "descriptive keys." The advantage of descriptive keys is that they give both the characteristic features of the families and their differences. The delimitation of families and orders drastically differs from the one accepted by the Englerian school and from the one accepted in Arthur Cronquist's system. Takhtajan favors the smaller, more natural families and orders, which are more coherent and better-defined, where characters are easily grasped, and which are more suitable for information retrieval and phylogenetic studies, including cladistic analysis (because it reduces polymorphic codings).
