Available in PDF, EPUB and Kindle. Book excerpt: Tropical forests affect climate, and the removal of the forests will change climate. Or not? This book discusses basic questions on how far, if at all, tropical deforestation leads to climatic change. The question of this uncertainty is particularly addressed. One important consequence of the uncertainties of whether deforestation affects climate is how scientific findings best illuminate the policy-making process.

Download or read book Tropical Forests Management and Ecology written by Ariel E. Lugo and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 474 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forestry professors used to remind students that, whereas physicians bury their mistakes, foresters die before theirs are noticed. But good institutions live longer than the scientists who contribute to building them, and the half-century of work of the USDA Forest Service's Institute of Tropical Forestry (ITF) is in plain view: an unprecedented corpus of accomplishments that would instill pride in any organization. There is scarcely anyone interested in current issues of tropical forestry who would not benefit from a refresher course in ITF's findings: its early collaboration with farmers to establish plantations, its successes in what we now call social forestry, its continuous improvement of nursery practices, its screening trials of native species, its development of wood-processing technologies appropriate for developing countries, its thorough analysis of tropical forest function, and its holistic approach toward conservation of endangered species. Fortunately, ITF has a long history of information exchange through teaching; like many others, I got my own start in tropical forest ecology fromjust such a course in Puerto Rico. And long before politicians recognized the global importance of tropical forestry, the ITF staff served actively as ambassadors of the discipline, visiting tropical coun tries everywhere to learn and, when invited to do so, to help solve local problems. It is a general principle of biogeography that species' turnover rates on islands are higher than those on continents. Inevitably, the same is true of scientists assigned to work on islands.

Download or read book The Rise and Fall of Modern Empires Volume II written by Saul Dubow and published by Routledge. This book was released on 2016-12-05 with total page 656 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume reproduces key historical texts concerning `colonial knowledges’. The use of the adjective 'colonial' indicates that knowledge is shaped by power relationships, while the use of the plural form, ’knowledges’ indicates the emphasis in this collection is on an interplay between different, often competing, cognitive systems. George Balandier’s notion of the colonial situation is an organising principle that runs throughout the volume, and there are four sub-themes: language and texts, categorical knowledge, the circulation of knowledge and indigenous knowledge. The volume is designed to introduce students to a range of important interventions which speak to each other today, even if they were not intended to do so when first published. An introductory essay links the themes together and explains the significance of the individual articles.

Download or read book Carcasson s African Butterflies written by PR Ackery and published by CSIRO PUBLISHING. This book was released on 1995-01-01 with total page 1626 pages. Available in PDF, EPUB and Kindle. Book excerpt: The result of more than 20 years of research and collaboration by international butterfly experts, this book is the first comprehensive catalogue to the butterfly fauna of any major tropical region and, as such, provides a basic research tool for any worker with an interest in African butterflies. Covering 3593 recognised species in 300 genera, it deals with about 20% of the world butterfly fauna. Included are entries for all genus-group, species-group and infra-subspecific names applicable to the Afrotropical butterflies, a total of about 14 000 names. This work has a more wide-ranging appeal than a narrow taxonomic list, a volume that will be of value not only to taxonomists but to all biologists with an interest in Africa and its butterfly fauna.

Download or read book Guide to Standard Floras of the World written by David G. Frodin and published by Cambridge University Press. This book was released on 2001-06-14 with total page 1136 pages. Available in PDF, EPUB and Kindle. Book excerpt: This 2001 book provides a selective annotated bibliography of the principal floras and related works of inventory for vascular plants. The second edition was completely updated and expanded to take into account the substantial literature of the late twentieth century, and features a more fully developed review of the history of floristic documentation. The works covered are principally specialist publications such as floras, checklists, distribution atlases, systematic iconographies and enumerations or catalogues, although a relatively few more popularly oriented books are also included. The Guide is organised in ten geographical divisions, with these successively divided into regions and units, each of which is prefaced with a historical review of floristic studies. In addition to the bibliography, the book includes general chapters on botanical bibliography, the history of floras, and general principles and current trends, plus an appendix on bibliographic searching, a lexicon of serial abbreviations, and author and geographical indexes.
Download or read book Plants and vegetation of NW Ethiopia written by Ib Friis and published by Firenze University Press. This book was released on with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pichi Sermolli’s work with his more than 2750 collections of plants from nearly 150 localities on the Lake Tana expedition in Ethiopia in 1937 was interrupted by World War II, but completed in 1947 at the Royal Botanic Gardens, Kew, and the British Museum (Natural History), UK. It resulted in preliminary accounts of the vegetation published 1938-40 and a taxonomically arranged account in 1951, all in Italian. Pichi Sermolli’s observations are difficult to locate due to the imperfect maps of the time, but in this book the authors have reconstructed the sequence of the collections, georeferenced the localities, and updated the identifications of the species. By reconstructing Pichi Sermolli’s observations, it is possible to draw conclusions about the vegetation and compare with a recent model of the vegetation of Ethiopia. According to this, the vegetation of the Lake Tana Basin was a complex mosaic of woodland, scrub, forest, farmland and lake shore vegetation now difficult to interpret in detail. Pichi Sermolli’s study of the vegetation in the Semien Mountains demonstrated for the first time the zonation of Ericaceous woodland and Afroalpine vegetation, within which he distinguished Carex monostachya bogs, Afroalpine grasslands with Lobelia rhynchopetalum, and stony and rocky Afroalpine vegetation. This book interprets Pichi Sermolli’s observations in English and compares them with modern knowledge of the region, partly obtained by the present authors’ own field work. It demonstrates how Pichi Sermolli’s studies form a valuable contribution to the understanding of the Ethiopian flora and vegetation.
Download or read book The Rainforests of West Africa written by MARTIN and published by Birkhäuser. This book was released on 2013-11-11 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nowhere eise in the world did industrialized countries leave such early marks in the rainforest as in West Africa. Past and present developments here are in one way or the other significant for rainforests on other continents as weil. West Africa is a pioneer in both a good and a bad sense. This is reason enough to take a closer Iook at the history of moist tropical West Africa. Until recently, no one really seemed to be interested in the rainforests except for a few specialists. The world's scientific community neglected to study the incalculable riches of tropical forests, to make the public aware of them and their due importance. Although interdisciplinary research has been a popular topic for some decades now, it was not applied to just the most complex habitat on earth. Scientists from all fields studied only that which was easiest to record, seemingly blind to a myriad of details awaiting closer examination. Botanists wentabout establishing their herbariums and paid much too little attention to the vegetation as a whole, or to the significance of useful plants for local populations. Zoologists, too, busied themselves with collecting and describing species. Anthropologists, on the other hand, tended to overlook faunal details: in their ignorance of the animal world, they wrote of tigers and deer in Africa. And finally, foresters saw neither the forest nor the trees for the timber - and even confused rainforests with monocultures of fir trees.
