Download or read book Revision of Pearcea Gesneriaceae written by Lars Peter Kvist and published by . This book was released on 1996 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seventeen species of Pearcea (Gesneriaceae) are recognized, nine of which are new: Pearcea bella, P. bilabiata, P. cordata, P. fuscicalyx, P. glabrata, P. gracilis, P. grandifolia, P. intermedia, and P. strigosa. Of the remaining eight species, two were originally described in Pearcea, one is transferred herein from Kohleria, and five come from Parakohleria, a genus placed in synonymy herein. Pearcea occurs mainly on the eastern Andean slopes of Colombia (5 species), Ecuador (12 species), Peru (6 species), and Bolivia (1 species), and one species also occurs on the western Andean slopes in Ecuador. The largest number of species appears to occur in Ecuador, although additional species may occur in less explored parts of Peru. Pearcea differs from related and similar genera in the Gloxinieae by having fleshy capsules dehiscing by two valves and exposing a sticky seed mass. All species are herbs, usually with bright red flowers, and are usually found in the shady, humid forest understory, often near small streams. Hybridization, local speciation, and polymorphic variation may complicate the species delimitation. The variable Pearcea sprucei occurs throughout nearly the entire range of the genus (and includes the only accepted variety, var. parviflora), but most species are rare and local.

Available in PDF, EPUB and Kindle. Book excerpt: A marvelously illustrated reference to the natural wonders of one of the most spectacular places on earth Separated from Africa’s mainland for tens of millions of years, Madagascar has evolved a breathtaking wealth of biodiversity, becoming home to thousands of species found nowhere else on the planet.

Download or read book Atlas of Butterflies and Diurnal Moths in the Monsoon Tropics of Northern Australia written by Michael Braby and published by ANU Press. This book was released on 2018-12-07 with total page 463 pages. Available in PDF, EPUB and Kindle. Book excerpt: Northern Australia is one of few tropical places left on Earth in which biodiversity—and the ecological processes underpinning that biodiversity—is still relatively intact. However, scientific knowledge of that biodiversity is still in its infancy and the region remains a frontier for biological discovery. The butterfly and diurnal moth assemblages of the area, and their intimate associations with vascular plants (and sometimes ants), exemplify these points. However, the opportunity to fill knowledge gaps is quickly closing: proposals for substantial development and exploitation of Australia’s north will inevitably repeat the ecological devastation that has occurred in temperate southern Australia—loss of species, loss of ecological communities, fragmentation of populations, disruption of healthy ecosystem function and so on—all of which will diminish the value of the natural heritage of the region before it is fully understood and appreciated. Written by several experts in the field, the main purpose of this atlas is to compile a comprehensive inventory of the butterflies and diurnal moths of northern Australia to form the scientific baseline against which the extent and direction of change can be assessed in the future. Such information will also assist in identifying the region’s biological assets, to inform policy and management agencies and to set priorities for biodiversity conservation.
Download or read book Inselbergs written by S. Porembski and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 543 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inselbergs are isolated rock outcrops that stand out abruptly from surrounding plains. Despite the widespread occurrence of granite inselbergs throughout all climatic and vegetational zones, their remarkably rich plant life was largely neglected in the recent literature. This richly and partly in color illustrated volume provides a detailed survey of all major abiotic and biotic features characteristic for inselbergs. The extreme environmental conditions on inselbergs are described in depth as well as specific adaptive traits of rock outcrop plants including their morphological, anatomical and physiological responses. The diversity and structure of inselberg plant communities are examined on a global scale with detailed regional accounts for different tropical and temperate zones.

Download or read book Flowering Plants Eudicots written by Klaus Kubitzki and published by Springer Science & Business Media. This book was released on 2013-11-27 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume presents systematic treatments for the families and genera of the Malpighiales, which more recently have been recognised as a new major group of the eudicots. Apart from several herbaceous lineages (already treated in Vol. IX of this series), the order consists mainly of rainforest trees, particularly those of the understorey. Accompanied by other early eudicot lineages, this reflects the well-documented origin of the group as invaders into the conifer-, cycad- and seed fern-dominated forests of the Cretaceous which, at that time, were transformed into the tropical rainforest biome. In this volume, 24 families with 429 genera comprising over 12,000 species are treated. Many of these belong to the vast family of the Euphorbiaceae (here conceived in a broader sense), followed by the Violaceae, whereas some of the remaining families are very small and even relictual. The revised classification includes a complete inventory of the genera belonging to the families treated in this volume, along with their diagnostic features and keys for their identification. References to the latest taxonomic literature and links to many different disciplines important to modern plant systematics make the volume a valuable source of information on the manifold aspects of plant diversity.

Download or read book Tropical Forest Community Ecology written by Walter Carson and published by John Wiley & Sons. This book was released on 2011-08-31 with total page 686 pages. Available in PDF, EPUB and Kindle. Book excerpt: Historically, tropical ecology has been a science often content with descriptive and demographic approaches, which is understandable given the difficulty of studying these ecosystems and the need for basic demographic information. Nonetheless, over the last several years, tropical ecologists have begun to test more sophisticated ecological theory and are now beginning to address a broad array of questions that are of particular importance to tropical systems, and ecology in general. Why are there are so many species in tropical forests and what mechanisms are responsible for the maintenance of that vast species diversity? What factors control species coexistence? Are there common patterns of species abundance and distribution across broad geographic scales? What is the role of trophic interactions in these complex ecosystems? How can these fragile ecosystems be conserved? Containing contributions from some of the world’s leading tropical ecologists, Tropical Forest Community Ecology provides a summary of the key issues in the discipline of tropical ecology: Includes contributions from some of the world’s leading tropical ecologists Covers patterns of species distribution, the maintenance of species diversity, the community ecology of tropical animals, forest regeneration and conservation of tropical ecosystems
Download or read book Cactus and Succulent Plants written by Sara Oldfield and published by World Conservation Union. This book was released on 1997-01 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: Found in a variety of forms, cacti and other succulents have elicited widespread interest and tremendous popularity worldwide. Although the subject of a certain amount of debate, about 10,000 species are recognized as belonging to the succulent group. Of these, an estimated 2,000 are threatened with global extinction in the wild and many more are regionally or nationally threatened mainly due to habitat destruction and collection for international trade.This Action Plan brings together from around the world current information on population status, threats and conservation of this particularly important group of plants. Prepared with conservationists, scientists, governments, protected area managers and grant-awarding bodies in mind, it suggests priorities for action and encourages collaboration among interested parties at all levels.
