Invasive Plant Ecology


Book Description

Invasion of non-native plant species, which has a significant impact on the earth's ecosystems, has greatly increased in recent years due to expanding trade and transport among different countries. Understanding the ecological principles underlying the invasive process as well as the characteristics of the invasive plants is crucial for making good

A History of the Water Hyacinth in Africa


Book Description

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.







The East African Great Lakes: Limnology, Palaeolimnology and Biodiversity


Book Description

The Second International Symposium on the East African Lakes was held from 10-15 January 2000 at Club Makokola on the southern shore of Lake Malawi. The symposium was organized by the International Decade for the East African Lakes (IDEAL), a research consortium of African, European and North American scientists interested in promoting the investigations of African Great Lakes as archives of environmental and climatic dynamics. Over one hundred African, European and North American scientists with special expertise in the tropical lakes participated in the symposium which featured compelling presentations on the limnology, climatology, palaeoclimatology and biodiversity of the East African Lakes. It is their papers that comprise this book. The large lakes of East Africa are important natural resources that are heavily utilized by their bordering countries for transportation, water supply, fisheries, waste disposal, recreation and tourism. The lakes are unique in many ways: they are sensitive to climatic change and their circulation dynamics, water-column chemistry and biological complexity differ significantly from large lakes at higher latitudes; they have long, continuous, high resolution records of past climatic change; and they have rich and diverse populations of endemic organisms. These unique properties and the significance of the palaeolimnological records demand and attract research interest from around the world.
