Bio-Geo Interactions in Metal-Contaminated Soils (Soil Biology #31)

by Erika Kothe and Ajit Varma

Metal contamination is an increasing ecological and eco-toxicological risk. Understanding the processes involved in metal mobilization, sorption and mineralization in soils are key features for soil bioremediation.Following an introduction to the physical, chemical and biological components of contaminated soils, various chapters address the interactions of soil, microorganisms, plants and the water phase necessary to transfer metals into biological systems. These include topics such as potential hazards at mining sites; rare earth elements in biotic and abiotic acidic systems; manganese redox reactions; biomineralisation, uranium in seepage water; metal-resistant streptomycetes; mycorrhiza in re-forestation; metal (hyper)accummulation in plants; microbial metal uptake; and their potential for bioremediation.This book will be of interest to soil biologists, geologists and chemists, researchers and graduate students, as well as consulting companies and small enterprises involved in bioremediation.

Bioactive Compounds in Agricultural Soils

by Lech Wojciech Szajdak

This volume looks at the impact that different cropping systems and tillage have on soil’s biologically active substances. It considers how phytotoxins accumulate and can inhibit the development of cultivated plants. Coverage explores the continuous cropping of rye, crop rotation, no tillage, and conventional tillage. It offers a comprehensive, comparative approach to allelopathic plant-soil interactions.The authors focus on free and bounded biologically active substances such as amino acids, auxins, humic and fulvic acids, transient radicals, and enzymes in light sand soils fertilized with different mineral and organic fertilizers.The chapters address fundamental questions relevant to the environmental challenges we face today and will deal with in the future. The results involve asking basic questions motivated by soil's chemical and biochemical processes. The answers will lead to the improvement of the quality of soil’s organic matter, which, in turn, can lead to increased crop yields.Readers will come to understand the relationship between ecological processes and environmental change on individual levels of biocomplexity as well as on systems in their entirety. The title is ideal for students and teachers for laboratory practical classes. Soil scientists, biochemists, chemists, plant ecophysiologists, “Natural Products” organic chemists, and other environmental scientists and specialists will also find it useful.

Bioarchaeology of Climate Change and Violence: Ethical Considerations (SpringerBriefs in Anthropology #6)

by Ryan P. Harrod Debra L. Martin

The goal of this monograph is to emphasize with empirical data the complexity of the relationship between climate change and violence. Bioarchaeology is the integration of human skeletal remains from ancient societies with the cultural and environmental context. Information on mortality, disease, diet and other factors provide important data to examine long chronologies of human existence, particularly during periods of droughts and life-threatening climate changes. Case studies are used to reconstruct the responses and short and long-term adaptations made by groups before, during and after dramatic changes in weather and climate. Interpersonal and group violence is also analyzed. The authors find that while in some cases there is an increase in trauma and violence, in other cases there is not. Human groups are capable of avoiding violent altercations and increasing broad networks of cooperation that help to mitigate the effects of climate change. A case study from the U.S. Southwest is provided that shows the variable and surprising ways that ancient farmers in the past dealt with long term droughts.

Bioavailability of Organic Xenobiotics in the Environment: Practical Consequences for the Environment (NATO Science Partnership Subseries: 2 #64)

by Philippe Baveye

In the continuing fight against organic environmental xenobiotics, the initial success attributed to bioremediation has paled, in part due to the low availability of xenobiotics entrapped within a soil or sediment matrix. This has generated a very significant wave of interest in the bioavailability issue. However, much experimental evidence is puzzling or contradictory, mechanistic theories are embryonic, and implications for the practice of bioremediation or concerning the natural fate of xenobiotics are still tentative. The debate in Europe and the USA is vigorous. Eastern Europe, following the liberalisation of the economy and political life, is evolving in a similar direction. In many cases, however, limited access to literature sources, severe language barriers, and the lack of a strong pluridisciplinary tradition are hampering the adoption of state of the art techniques. Originally intended to allow scientists in East European countries to become acquainted with the key aspects of the bioavailability debate that is unfolding in the scientific literature in the West, and with its implications for bioremediation efforts, the present book presents a very complete coverage of the theoretical and practical aspects of the (limited) bioavailability of organic xenobiotics in the environment.

Bioceramics Calcium Phosphate

by K. de Groot

The first chapters are fundamental, in that the physical chemistry of calcium phosphate salts is discussed, along with mineralization (with emphasis on teeth) and remodelling of mineralized tissues. Thereafter follows a treatment of the influence of implants o surrounding hard tissues. This topic is followed by a chapter on preparation methods and biomechanical and biological aspects of calcium phosphate implants. In conclusion, two chapters are devoted to (possible) dental and medical applications. It is hoped that basic researchers can use the book in their efforts to improve this promising class of materials further, and that clinicians are inspired to define further possibilities and � at least as important � limitations.

Bioclimatology and Biogeography of Africa

by Henry N. Houérou

Covering an area of over 130 million km2 spanning the Mediterranean, equator and tropics, the African continent features a spectacular geographic diversity. Consequently, it is characterised by extremely variable climatic, edaphic and ecological conditions, associated with a wide range of natural vegetation and wildlife, as well as human population density, crops and livestock. In this book, Henry Le Houérou presents his bioclimatic and biogeographic classification of Africa. The extensive data provide the basis for comparisons between various African regions, and with regions on other continents such as Latin America or the Indian subcontinent. The results constitute a rational basis for national, regional and sub-regional rural development planning, and for agricultural research dealing with aspects such as plant and animal introductions, the extrapolation or interpolation of experimental or developmental findings, and ecosystems dynamics. Possible problems of applications are also examined.

Bioclimatology and Natural Hazards

by Katarína Strelcová Miroslav Blazenec Jan Holecy Axel Kleidon Milan Lapin Frantisek Matejka Csaba Matyas Jaroslav Skvarenina

Anthropogenic influences to the earth's system, including the atmosphere, hydrosphere, biosphere, cryosphere and lithosphere, represent a serious challenge to our planet's ecosystems and natural environments. Bioclimatology, hydrology, bio-hydrology and eco-physiology are important scientific research areas with wide application to environmental protection, forestry, agriculture and water management, and protection against natural hazards including droughts, floods, windstorms, weather extremes, and wild fires. Bioclimatology helps to better understand the causes and impacts of natural hazards and how to prevent them. Improved knowledge of natural hazards is a vital prerequisite for the implementation of integrated resource management. It provides a useful framework for combating current climate variability and for adapting to ongoing climate change. This book presents research on the interactions between meteorological, climatological, hydrological and biological processes in the atmospheric and terrestrial environment. It highlights a spectrum of topics associated with climate change and weather extremes and their impact on different economic sectors. The contributing authors come from renowned scientific research institutions and universities and specialise in issues of climate change, soil-plant-atmosphere interactions, hydrologic cycle, ecosystems, biosphere, and natural hazards.

The Bioclimatology of Frost: Its Occurrence, Impact and Protection (Advances in Bioclimatology #2)

by J. D. Kalma G. P. Laughlin J. M. Caprio P.J.C. Hamer

The economic costs of frosts in agriculture and horticulture in many parts of the world can be very significant. Reports in the media include accounts on how frosts have devastated coffee crops in Brazil or in Papua New Guinea, and how frosts have seriously damaged the Florida citrus industry. Frost may cause losses in current harvests or a decline in future yields through more permanent damage to trees and bushes. Damaging frosts may occur as infrequent, short-term events with sub-zero temperatures or with unusually severe winter temperatures which extend over long periods. In this book we have aimed at providing a comprehensive review of recent advances in the area of frost research. The stimulus for writing this book has come from the recognition that there is a shortage of recent texts which deal exclusively with the bioclimatology of frost. Bioclimatology deals with the relations between climate and life and the present text is particularly concerned with the effects of low temperatures on plants. Our purpose has been to assist researchers, engineers, extension officers and students in understanding the physical aspects of frost occurrence and frost distribution as well as the biological and phenological aspects of frost damage and to provide an overview of direct and indirect methods of frost pro­ tection and prevention.

Biocommunication in Soil Microorganisms (Soil Biology #23)

by Günther Witzany

Communication is defined as an interaction between at least two living agents which share a repertoire of signs. These are combined according to syntactic, semantic and context-dependent, pragmatic rules in order to coordinate behavior. This volume deals with the important roles of soil bacteria in parasitic and symbiotic interactions with viruses, plants, animals and fungi. Starting with a general overview of the key levels of communication between bacteria, further reviews examine the various aspects of intracellular as well as intercellular biocommunication between soil microorganisms. This includes the various levels of biocommunication between phages and bacteria, between soil algae and bacteria, and between bacteria, fungi and plants in the rhizosphere, the role of plasmids and transposons, horizontal gene transfer, quorum sensing and quorum quenching, bacterial-host cohabitation, phage-mediated genetic exchange and soil viral ecology.

Biocultural Landscapes: Diversity, Functions and Values

by Sun-Kee Hong Jan Bogaert Qingwen Min

This book is devoted to the cultural and biological dimensions and values of landscapes, linking the concepts of biodiversity, landscape and culture and presenting an essential approach for landscape analysis, interpretation and sustainable dynamics.Early chapters explore the concepts and values of biocultural landscapes, before addressing the methodology to identify the relationship between biological and cultural diversity. The volume continuous with a series of case studies and with an exploration of the key role of biocultural diversity in contemporary landscape ecology.Readers will learn the importance of landscapes for different fields of natural and human sciences and are confronted to the trans-disciplinary nature of the landscape concept itself. A hierarchical approach to landscapes, in which they are composed of interacting (eco)systems, is shown to be essential in recognizing their emergent properties.In this work, the biocultural values of landscapes are explored through their diversity in geographical scopes, methodological approaches and conceptual assumptions. Authors from Asia, Europe and North-America present diverse research experiences and views on biocultural landscapes, their pattern, conservation and management.Landscape ecologists will find this work particularly appealing, as well as anyone with an interest in sustainable landscape development, nature conservation or cultural heritage management.This volume is the outcome of a symposium on “Biodiversity in Cultural Landscapes”, organized in the framework of the 8th IALE World Congress, held in Beijing in 2011.

Biocultural Rights, Indigenous Peoples and Local Communities: Protecting Culture and the Environment (Routledge Explorations in Environmental Studies)

by Fabien Girard

This volume presents a comprehensive overview of biocultural rights, examining how we can promote the role of indigenous peoples and local communities as environmental stewards and how we can ensure that their ways of life are protected. With Biocultural Community Protocols (BCPs) or Community Protocols (CPs) being increasingly seen as a powerful way of tackling this immense challenge, this book investigates these new instruments and considers the lessons that can be learnt about the situation of indigenous peoples and local communities. It opens with theoretical insights which provide the reader with foundational concepts such as biocultural diversity, biocultural rights and community rule-making. In Part Two, the book moves on to community protocols within the Access Benefit Sharing (ABS) context, while taking a glimpse into the nature and role of community protocols beyond issues of access to genetic resources and traditional knowledge. A thorough review of specific cases drawn from field-based research around the world is presented in this part. Comprehensive chapters also explore the negotiation process and raise stimulating questions about the role of international brokers and organizations and the way they can use BCPs/CPs as disciplinary tools for national and regional planning or to serve powerful institutional interests. Finally, the third part of the book considers whether BCPs/CPs, notably through their emphasis on "stewardship of nature" and "tradition", can be seen as problematic arrangements that constrain indigenous peoples within the Western imagination, without any hope of them reconstructing their identities according to their own visions, or whether they can be seen as political tools and representational strategies used by indigenous peoples in their struggle for greater rights to their land, territories and resources, and for more political space. This volume will be of great interest to students and scholars of environmental law, indigenous peoples, biodiversity conservation and environmental anthropology. It will also be of great use to professionals and policymakers involved in environmental management and the protection of indigenous rights.
