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 Traveling Cultures and Plants written by Andrea Pieroni and published by Berghahn Books. This book was released on 2009-10 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: The tremendous increase in migrations and diasporas of human groups in the last decades are not only bringing along challenging issues for society, especially related to the economic and political management of multiculturalism and culturally effective health care, but they are also creating dramatic changes in traditional knowledge, believes and practices (KBP) related to (medicinal) plant use. The contributors to this volume – all internationally recognized scholars in the field of ethnobiology, transcultural pharmacy, and medical anthropology – analyze these dynamics of traditional knowledge in especially 12 selected case studies. Ina Vandebroek, features in Nova's "Secret Life of Scientists", answering the question: just what is ethnobotany?
Download or read book Uan Tabu in the Settlement History of the Libyan Sahara written by Elena A. A. Garcea and published by All’Insegna del Giglio. This book was released on 2001-07-01 with total page 281 pages. Available in PDF, EPUB and Kindle. Book excerpt: Uan Tabu is a rockshelter on the left bank of the central valley of the Wadi Teshuinat, which is a main ancient water course in the Tadrart Acacus mountain range. It is located in the Fezzan region, south-western Libya (Great Jamahirya). The site was discovered by Fabrizio Mori in 1960 and was re-excavated and studied by a multi-disciplinary team at the beginning of the 1990s. It has also remarkable rock art that includes paintings from the Round Head and Pastoral phases. Between 1960 and 1963, a trench was dug into the archaeological deposit at the foot of the rock wall. The results of the 1960s’ excavation have never been published before, apart from some brief notes. They are thoroughly described and discussed in the present volume. Between 1990 and 1993, the excavation was resumed and extended. The 1990s’ excavation has been preliminarily published. Further information and details are now presented and commented. A stratigraphic and cultural correlation between the two excavations is also attempted in this volume. Four main archaeological and paedological units were identified and dated. They spanned from the Late Pleistocene to the Late Holocene. The earliest one, dating to the Pleistocene, included an Aterian techno-complex and was dated to around 61,000 years BP. Later, during the Early Holocene, a ‘pre-pastoral’ occupation occurred since the 10th millennium bp. This period was differentiated in two phases characterised by different socio-cultural systems: 1. during the Early Acacus (around 9800-8800 years bp), the site was used on a seasonal basis, probably during the dry season, for practising hunting activities; 2. during the Late Acacus (around 8800-8600 years bp), a more sedentary lifestyle was hypothesised for the inhabitants of the site. These two cultural facies comprised the upper three units. The fourth phase of occupation of the shelter was only attested to the surface of the site, but it could be still considered as an indication of the use of the site during the Late Holocene, as late as the 4th millennium bp. A dung fill in the wall of the rockshelter dated to the end of this, Late Pastoral, phase and is the only evidence for domesticated animals.

Download or read book Bioclimatology and Biogeography of Africa written by Henry N. Houérou and published by Springer Science & Business Media. This book was released on 2008-12-10 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: Covering an area of over 130 million km2 spanning the Mediterranean, equator and tropics, the African continent features a spectacular geographic diversity. Consequently, it is characterised by extremely variable climatic, edaphic and ecological conditions, associated with a wide range of natural vegetation and wildlife, as well as human population density, crops and livestock. In this book, Henry Le Houérou presents his bioclimatic and biogeographic classification of Africa. The extensive data provide the basis for comparisons between various African regions, and with regions on other continents such as Latin America or the Indian subcontinent. The results constitute a rational basis for national, regional and sub-regional rural development planning, and for agricultural research dealing with aspects such as plant and animal introductions, the extrapolation or interpolation of experimental or developmental findings, and ecosystems dynamics. Possible problems of applications are also examined.
Download or read book Quaternary Vegetation Dynamics written by Jürgen Runge and published by CRC Press. This book was released on 2021-11-28 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book celebrates the relaunch of the African Pollen Database, presents state-of-the-art of modern and ancient pollen data from sub-Saharan Africa, and promotes Open Access science. Pollen grains are powerful tools for the study of past vegetation dynamics because they preserve well within sedimentary deposits and have a huge diversity in ornamentation that allows different taxa to be determined. The reconstruction of past vegetation from the examination of ancient pollen records thus can be used to characterize the nature of past landscapes (e.g. abundance of forests vs. grasslands), provide insights into changes in biodiversity, and gain empirical evidence of vegetation response to climatic change and human activity. In this, the 35th Volume of "Palaeoecology of Africa", we bring together new data and extensive synthetic reviews to provide novel insights into the relationships between human evolution, human activity, climate change and vegetation dynamics during the Quaternary, the last 2.6 million years. Current and ongoing climate and land-use change is exerting pressure on modern vegetation formations and threatening the livelihoods and wellbeing of many peoples in Africa. In this book the focus is on the Quaternary because it is during this geological period that the modern vegetation formations developed into their current configurations against a backdrop of high magnitude global climate change (glacial-interglacial cycles), human evolution, and a growing human land-use footprint. In this book the latest information is presented and collated from around the African continent to parameterize past vegetation states, identify the drivers of vegetation change, and assess the vegetation resilience to change. To achieve this research from two broad themes are covered: (i) the present is the key to the past (i.e. studies which improve our understanding of modern environments so that we can better interpret evidence from the past), and (ii) the past is the key to the future (i.e. studies which unlock information on how and why vegetation changed in the past so one can better anticipate trajectories of future change). This Open Access book will provide a strong foundation for future research exploring past ecological, environmental and climatic change within Africa and the surrounding islands. The book is organized regionally (covering western, eastern, central, and southern Africa) and it contains specialized articles focused on particular topics (such as modern pollen-vegetation relationships and fire as a driver of vegetation change), as well as regional and pan-African syntheses drawing together decades of research to assess key scientific questions (including the role of climate in driving vegetation change and the role of vegetation change in human evolution). These articles will be useful to students and teachers from high school to the highest level of university who are interested in the origins and dynamics of vegetation in Africa. Furthermore, it is also meant to provide societally relevant information that can act as an inspiration for the development of sustainable management practices for the future.
Download or read book New Strategies in Locust Control written by Stephan Krall and published by Springer Science & Business Media. This book was released on 1997-12-01 with total page 560 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the late eighties large-scale control operations were carried out to control a major desert locust upsurge in Africa. For the first time since the banning of organochlorine pesticides these operations relied mainly on non-persistent pesticides such as organophosphates and pyrethroids. The amount of pesticides sprayed and the area covered were probably the highest in the history of locust control and raised criticism with respect to efficacy, economic viability and environmental impact. As a consequence, applied research into the problem was intensified, both at the national and the international level, with the goal of finding new and environmentally sound approaches and solutions to locust and grasshopper control. Emphasis was laid on developing new control agents and techniques.
Download or read book Sahara Desert written by J. L. Cloudsley-Thompson and published by Pergamon. This book was released on 1984 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first in a series of titles providing scientifically accurate, concise and well-illustrated accounts of major environments which are, or soon will be, under threat. This volume provides a vivid picture of the world's grandest and most awe-inspiring desert, the Sahara. Much of it man-made, mostly of comparatively recent origin, it is today expanding inexorably into the Sahel savanna bordering its southern flanks. Whether geographer, meteorologist, geologist, botanist, zoologist, sociologist or anthropologist no true scientist can fail to respond to the intellectual problems that emerge from the study of this immense zone of desolation, or to the exciting ideas that it generates.
