Available in PDF, EPUB and Kindle. Book excerpt: Humans and animals are not the only creatures that migrate. Plants also do. This book is a comprehensive and analytical account of the migration of an Old World plant, water hyacinth (also known to botanists as Eichhornia Crassipes) from the Amazon Basin and surrounding areas to Africa through human agency from about 1800 to the present. As an integrative work, which benefits from methodologies and conceptual approaches drawn from limnology, botany, biology, geography, history, ecology and other social sciences and humanities, the book further explores the political, economic, and ecological consequences of the spread of water hyacinth from its native habitat through European botanical gardens to Africa rivers, lakes, dams, and wetlands. In part, as a narrative of Western tinkering with African ecologies gone awry, the study has strong lessons for environmental historians, and social scientists as well as contemporary foundations, aid workers, development experts and African governments. Although it may appear to be a micro-history of a single plant, water hyacinth, it illuminates broader issues in the history of the modern environment in Africa and similar studies worldwide. This study is primarily rooted on the histories of colonialism, bioinvasion, environmental realities and experiences in Africa. The highly visible pathways of hyacinth’s spread across international frontiers along watercourses and communication networks means that not only is this a trans-boundary environmental affair, but one which directly involves bilateral relations between African states.

This book was released on 2012-12-06 with total page 355 pages. Available in PDF, EPUB and Kindle. Book excerpt: Interest in the biology of African 'wetlands' was initiated in the last century with the hypothesis that Lake Tanganyika was once part of a Jurassic sea, and was furthered by Cunnington's expedition at the beginning of this century which proved that it was not. In the late 1920's, ecological studies, encouraged by the growing importance of inland fisheries, were started hy British, French and Belgian biologists. Some twenty years later several government limnological research centres and fishery departments were established in tropical Africa, and scientific progress was accelerated. Scientific collaboration between the regions south of the Sahara was started formally in 1951 by the Scientific Council for Africa and stimulated by the International Biological Programme (1964-74) with its emphasis on biological productivity. Some of its interests were takcn on by SCOPE which recently selected continental wetlands as a Special Project; hence this book. The five authors, with-Patrick Denny as editor, have made a very valuable contribution both to science and to thc management of Africa's natural rcsourccs: thcy have filled a gap in the synthesis of knowledge about Africa's environments which is long overdue. The term 'wetland' is used today in several different contexts. For this purpose, it excludes the seas and large open inland waters. which are too deep for rooted plants, but includes the huge areas of floodplains and dambos which may change seasonally from standing water to very dry lands.

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.
