Guide to Freshwater Invertebrates (FBA Scientific Publication, #68)
by M. Dobson, S. Pawley, M. Fletcher, and A Powell
Contributed articles; with reference to India.
In this book, the authors take available information on freshwater systems and evaluate it within a modern ecological framework. They consider both lentic and lotic systems in an integrated fashion, emphasizing similarities and dissimilarities in biotic and and abiotic features. Their approach throughout is to describe basic ecological theory and to discuss the relevance and applicability to freshwater organisms. The book is aimed primarily at senior undergraduate and graduate student courses in...
The development of water resources in Africa has always been central to plans for its economic development. This book reveals how although reservoirs and irrigation schemes dot the landscape, environmental problems continue to dominate thinking and reportage on Africa's crisis. Far from helping to solve Africa's environmental problems, critics have said that large-scale water development projects have themselves added to existing, or have created wholly new, environmental problems. It is commonl...
The Life of Inland Waters: An Elementary Text Book of Fresh-Water Biology for American Students (Classic Reprint)
by James G Needham
This work is a textbook of fresh-water life dealing with its forms, its conditions, its fitnesses, its associations, and its economic aspects. The ecologic side of fresh-water biology is emphasized. Due consideration is given to the educational, economic, sanitary, social, civic, and aesthetic aspects of the subject.Limnology in America today is in its infancy. The value of its past achievements is just beginning to be appreciated. The benefits to come from a more intensive study of water life a...
Sustainable Sediment Management in Regulated Rivers
A unique feature of this book is that it deals with sustainable management of river sediments by explicitly incorporating sediment management in the planning, design and operation of dams, both to extend reservoir life and to minimize downstream impacts of sediment starvation. This book takes a river system perspective first, explaining how dams (and other anthropic actions such as aggregate mining) disrupt continuity of sediment transport, the consequences of that disruption, and opportunities...
The Ecohydrology of South American Rivers and Wetlands (IAHS Special Publications S., #6)
In 1947, South Asia emerged out of the colonial era with the world's largest centrally managed canal irrigation infrastructure. In 2007, its small-holder agriculture has come to overwhelmingly depend on a vast, atomistic irrigation economy with more than 25 million dispersed tube-well owners drawing groundwater without let or hindrance. What was an orderly irrigation economy, has now transformed into a colossal anarchy. How has this transformation come about? What are the drivers of this groundw...
If Rivers Could Sing: A Scottish River Wildlife Journey
by Keith Broomfield
Acidification is a serious problem for many lakes in Northern Europe and Eastern North America. There are, however, clear indications that the problem of lake acidification also may become a problem in many developing countries in the coming decades. This guidebook explains in detail the relations between the sources of air pollution, caused by sulphur and nitrogen oxides, and their effects on lakes. Management possibilities and strategies are also discussed.
The use of environmental assessment procedures within monitoring frameworks demands that there be some relevancy to the decisions that management agencies make using biological criteria. These biological criteria standards are the basis for environmental indicators, which provide a direct measure of environmental quality. Biological Response Signat
