The Heavy Metal Tolerant Flora Of Southcentral Africa

This volume provides a synthesis of recent work on evolutionary aspects of metal tolerance in plants. It presents contributions from scientists with a wide diversity of expertise. It covers the evolution of heavy metal tolerance in groups of plants, fungi, and protists. The book discusses the physiological, genetic and molecular aspects of metal tolerances. It deals with the evolution of populations in metal-contaminated environments. Several chapters include tolerance in animals in order to place the rest of the book on plants in proper perspective. This publication is an exciting addition for scientists with both applied and basic interest in metal toxicity and tolerance. It is of importance to those in vegetation ecology, land reclamation, agronomy, physiology, population ecology, ecological genetics, evolutionary biology and molecular biology.

The copper-cobalt outcrops of Upper Katanga and north-western Zambia host a particular flora which comprises an estimated 750 species of which more than 400 are treated in this copper-cobalt field guide. The aim of this book, resulting from several years of intensive field work and study, is to bring together the basic knowledges permitting an easy approach to the identification of a great number of the species to be encountered. More than 400 species are illustrated with color photographs and/or drawings together with comments concerning synonyms, habit, description, ecology and distribution. Plant species are listed and colour-coded according to classification: Cyanoprocaryota, lichenized Fungi, Anthocerophyta, Marchantiophyta and Bryophyta (red edge), Lycophyta and Monilophyta (green edge), Magnoliopsida (blue edge) and Liliopsida (yellow edge). An index allows easy location either according to genus and species. An account of the research on copper-cobalt ecosystems carried out during the last ten years in southeastern D.R. Congo is also presented. The editors have spent more than twenty years in the area concerned and have collected more than 8,500 voucher specimens, including eleven species new to science (holotypes).

Phytoremediation is an exciting, new technology that utilizes metal-accumulating plants to rid soil of heavy metal and radionuclides. Hyperaccumulation plants are an appealing and economical alternative to current methods of soil recovery. Phytoremediation of Contaminated Soil and Water is the most thorough literary examination of the subject available today. The successful implementation of phytoremediation depends on identifying plant material that is well adapted to specific toxic sites. Gentle remediation is then applied in situ, or at the contamination site. No soil excavation or transport is necessary. This severely contains the potential risk of the pollutants entering the food chain. And it's cost effective. The progress of modern man has created many sites contaminated with heavy metals. The effected land is toxic to plants and animals , which creates considerable public interest in remediation. But the commonly used remedies are ex situ, which poses an expensive dilemma and an even greater threat. Phytoremediation offers the prospect of a cheaper and healthier way to deal with this problem. Read Phytoremediation of Contaminated Soil and Water to learn just how far this burgeoning technology has developed.

September 1987, the Faculty Biology of the Vrije Universiteit, Amsterdam commemorated the fact that Prof. Dr. Wilfried Hans Otto Ernst had been active as a scientist for 25 years. This period of 25 years of scientific research started at the Institut flir Angewandte Botanik (Institute of Applied Botany) of the University of Munster, FRG. In 1965 he completed his Ph. D. thesis, entitled "Untersuchungen der Schwermetallpflanzengesellschaften Mitteleuropas unter Einschluss der Alpen. " He was appointed full Professor at the Department of Ecology of the Vrije Universiteit, Amsterdam in 1973. On the occasion of his 25th anniversary as a scientist, a promise was made, though in covert terms, which we could not redeem at that time. The promise held to offer Prof. Ernst a book, in which his former and present staffmembers, Ph. D. students and colle ages should write a review about their specialism concerning a central theme. Now, at the beginning of 1990 we consider the chapters of "Ecological Responses to Environmental Stresses" to be completed. The book reflects the wide range of research approaches that has been initiated and organized by Wilfried Ernst. The editors hope to have attained the primary aim of the production of the book of friends, that is to gather relevant papers of staff-members and colleagues of Wilfried Ernst. The title of the book "Ecological Responses to Environmental Stresses" covers the majority of the chapters included.

Written for researchers and practitioners in environmental pollution, management and ecology, this interdisciplinary account explores the ecological issues associated with industrial pollution to provide a complete picture of this important environmental problem from cause to effect to solution. Bringing together diverse viewpoints from academia and environmental agencies and regulators, the contributors cover such topics as biological resources of mining areas, biomonitoring of freshwater and marine ecosystems and risk assessment of contaminated land in order to explore important questions such as: What are the effects of pollutants on functional ecology and ecosystems? Do current monitoring techniques accurately signal the extent of industrial pollution? Does existing policy provide a coherent and practicable approach? Case studies from throughout the world illustrate major themes and provide valuable insights into the positive and negative effects of industrial pollution, the provision of appropriate monitoring schemes and the design of remediation and restoration strategies.

This first volume in the series provides a detailed treatment in ecotoxicology and stresses why genetics is important in understanding if and how chemical contaminants affect populations. Written by an array of international contributors from various fields covering mammals, invertebrates, fish, plants, as well as molecular ecotoxicology, this book considers both ecological/evolutionary consequences and practical implications of the interplay between chemical toxicants and the genetic population. In broadening the understanding of ecological response, this resource ranges from molecular to classical genetics, from plant to animal, from asexual to sexual, touching on some fundamental issues of evolutionary biology. In addition, gaps in our present understanding of genetic and ecotoxicological processes and future research directions have been identified.
