Biological Invasions assembles detailed information on components of the invasive-species problem from six continents. This volume reconfirms the diverse and unpredictable roles that non-native species assume as they invade new ecosystems: destruction of vital crops and forests, major damages to ecosystems leading to loss of biodiversity, soil erosion, and water loss. In addition, it covers the impact of disease organisms on human health and livestock. Information is provided on how the non-native species invade new ecosystems and the subsequent environmental effects of these invading species. Wherever possible, estimates on the economic impacts of
the invading species are included

A major challenge of the 21st Century will be to ensure sufficient global food production to cope with the burgeoning world population. Soils, Land and Food is a short text aimed at undergraduates, graduates, agricultural scientists and policy makers which describes how the use of technology in soil management can increase and sustain agricultural production. The book leads the reader through the development of techniques of land management and discusses reasons why some agricultural projects have succeeded while others have failed. It shows how surveying and protecting soils before new land is brought into cultivation, raising soil fertility, increasing inputs and improving economic conditions can all help to increase food production. Particular emphasis is placed on the need for both economic change and technological intervention in developing countries where, in many cases, food production will need to more than double in the next fifty years

Highlighting effective, analytical functions that have been found useful for the comparison of alternative management techniques to maximize water and nutrient resources, this reference describes the application of viable mathematical models in data analysis to increase crop growth and yields. Featuring solutions to various differential equations, the book covers the characteristics of the functions related to the phenomenological growth model. Including more than 1300 literature citations, display equations, tables, and figures and outlining an approach to mathematical crop modeling, Mathematical Models of Crop Growth and Yield will prove an invaluable resource

The authors review the key features of trace elements in soils, plants and the food web on which human beings survive. Currently, the quality of food is highlighted and has become a subject of broad studies of various disciplines. Minor inorganic constituents of food, trace elements, are of special interest due to their specific properties in both abiotic and biotic environmental compartments. Hence, there is a need for comprehensive information on the distribution of trace elements in given environmnetal compartments and organisms.
The authors' intention is to summarize up-to date interdisciplinary data for the concise presentation of our understanding of trace-element transfer in the chain from soil to man. Geochemical processes and information on international legislation on trace elements as both micronutrients and contaminants in soil and food are presented in parallel and are related to ecology and health risk assessments

The idea that living things and the atmosphere, oceans, and soils comprise an interactive, self-regulating system -- the Gaia concept -- was first proposed nearly thirty years ago. Since then researchers have been seeking new connections between life and the global environment. David Schwartzman contributes to that search by examining how the Earth's biosphere regulates itself over geologic time. Emphasizing long-term geologic trends -- not the short-term perturbations that have received so much media attention (e.g., the so-called greenhouse effect), the author presents and elucidates his theory of biospheric evolution.
Life, Temperature, and the Earth updates and modifies important aspects of the Gaia hypothesis in light of geochemical, geophysical, mathematical, and paleontological data that were either ignored or unavailable at the time the hypothesis was developed. Schwartzman argues that the Earth's climatic temperature has been biologically regulated amidst the backdrop of variable volcanic outgassing and an evolving sun. The key to this regulation -- discussed here in depth -- has been the progressive increase in life's promotion of weathering on land over geologic time. The book is the first to take note of strong evidence for much higher temperatures prior to about two billion years ago and their role in constraining the evolution of microbes and delaying the emergence of complex multicellular life.
Schwartzman sets the stage by introducing his theory of biospheric evolution and outlining the development of the Gaia concept during the 1980s and 1990s. He then presents a systematic exposition of the weathering process, discussing the habitability of the Earth over geologic time and the role of such abiotic factors as tectonics and the carbon geodynamic cycle in climatic evolution. The final third of the book turns to a reinterpretation of the surface temperature history of the Earth, positing a much warmer Precambrian Earth surface than conventionally believed and discussing the implications of this fact to evolutionary biology and bioastronomy (the search for life elsewhere in the universe).
Determining the history of climate and investigating the self-organization of the biosphere, Life, Temperature, and the Earth explores the very foundations of environmental science and illuminates the evolution of life itself

Atlas of igneous rocks and their textures A companion volume to the Atlas of Rock-forming Minerals in Thin Section, this full-colour handbook is designed to be used as a laboratory manual both by elementary students of earth sciences undertaking a study of igneous rocks in thin section under the microscope, and by more advanced students and teachers as a reference work. The book is divided into two parts — Part One is devoted to photographs of many of the common textures found in igneous rocks with brief descriptions accompanying each photograph. Part Two illustrates the appearance of examples of some sixty of the commonest (and a few not so common) igneous rock types; each photograph is accompanied by a brief description of the field of view shown. Nearly 300 full-colour photographs are included, and in many cases the same view is shown both in plane-polarized light and under crossed polars. A brief account of how thin sections can be prepared is included as an appendix. It is believed that the amateur geologist using these instructions will be able to make his own thin sections and, with the aid of a relatively simple microscope, enjoy the study of rocks in thin section

Atlas of sedimentary rocks under the microscope A third volume to accompany the successful Atlas of Rock-forming Minerals in Thin Section and Atlas of Igneous Rocks and Their Textures, this full-colour handbook presents over 200 colour illustrations of the common constituents and textures of sedimentary rocks as seen using thin sections or acetate peels. Since carbonate rocks show the greatest variety of grain types half the book is devoted to them, but the authors also cover sandstones, ironstones, phosphatic rocks, evaporites and cherts. In addition to the plates and their captions a short introduction outlines the classifications used and the staining techniques applied to most of the limestone samples. Like its predecessors, this atlas provides an essential guide and laboratory manual for geology students and teachers. Amateur geologists will also find much to help them enjoy the study of sedimentary rocks under the microscope with the aid of relatively simple equipment. A.E. Adams is Lecturer in Geology at the University of Manchester. W.S. MacKenzie is Emeritus Professor of Petrology at the University of Manchester. C. Guilford was formerly Superintendent of the Department of Geology at the University of Manchester

Biomining is the biotechnology that uses microorganisms to recover metals
in particular copper and gold, from ores and concentrates. Having developed from a very simple operational (in terms of both engineering and biology) process, biomining has developed into a multifaceted technology, to the extent that many of the largest industrial stirred tanks and heaps throughout the world are employed for bioprocessing minerals.
This book has a strong applied approach and describes emerging and established industrial processes, as well as the underlying theory of the process, and the biology of the microorganisms involved. Chapters have been written by personnel from leading biomining companies, consultants and internationally recognized researchers and academics
