Book Description
Leonard C. Beadle In contrast to the more sta bie oceans, inland waters are, on the geological time scale, short-lived and are subject to great fluctuations in chemical composition and physical features. Very few lakes and rivers have existed continuously for more than a million years, and the life of the majority is to be measured in thousands or less. Earth movements, erosion and long-term climatic changes in the past have caused many of them to appear and disappear. No wonder then that most freshwater organism are especially adapted to great changes and many even to temporary extinction of their environment. Recent studies of residual sediments from existing and extinct lakes in tropical Africa have told us much about their age and the past history of their faunas and floras, from which we may deduce something about the climate and the conditions in the water in the past. The forces that have formed and moulded the African Great Lakes have been catastrophic in their violence and effects. They are not yet finished, but the present rate of change is, in human terms, too slow for direct observation of the ecological effects. The large man-made lakes are providing very good opportunities for studying the chemi cal and biological consequences of the initial filling but, once filled, they are artificially protected against major fluctuations.
Lessons from Amazonia

Book Description
Deforestation is occurring at an alarming rate in many parts of the world, causing destruction of natural habitat and fragmentation of what remains. Nowhere is this problem more pressing than in the Amazon rainforest, which is rapidly vanishing in the face of enormous pressure from humans to exploit it. This book presents the results of the longest-running and most comprehensive study of forest fragmentation ever undertaken, the Biological Dynamics of Forest Fragments Project (BDFFP) in central Amazonia, the only experimental study of tropical forest fragmentation in which baseline data are available before isolation from continuous forest took place.A joint project of Brazil’s National Institute for Research in Amazonia and the U.S. Smithsonian Institution, the BDFFP has investigated the many effects that habitat fragmentation has on plants, invertebrates, and vertebrates. The book provides an overview of the BDFFP, reports on its case studies, looks at forest ecology and tree genetics, and considers what issues are involved in establishing conservation and management guidelines.

Book Description
* Emphasizes the molecular genetics of antibiotic production * Provides the latest information on the organization of genes encoding the biosynthetic pathway * Explores the mechanisms governing their expression and regulation * Examines the role of resistance genes in protecting organisms from their own lethal productsGenetics and Biochemistry of Antibiotic Production brings together the most up-to-date information on the genetic and biochemical mechanisms involved in antibiotic production. A collection of internationally recognized authors provide the latest information on the organization, function and regulation of genes responsible for antibiotic synthesis in a range of bacteria. This unique book groups antibiotics according to their biosynthetic affiliation, providing a background into evolutionaryrelationships while raising intriguing questions about the raison d'etre of antibiotics in nature.
