Biomining
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
Biology and Ecology of Norway Spruce
This book presents a concise and comprehensive review of the biology, ecology, and management of Norway spruce. It integrates classic and contemporary literature (more than 2000 works cited in the text), highlighting basic research and forestry practices in central and eastern Europe. The topics include anatomy and morphology, physiology and nutrition, reproductive biology and genetics, and ecology. In addition, it examines mycorrhiza, diseases and pests as well as silviculture and wood products. In the light of increasing threats to forest health from air pollution, climate change, and insects and disease, it provides an essential information source to those concerned with the ecology, conservation, and management of the species
Biological Calcification : Normal and Pathological Processes in the Early Stages
This book follows a precursor volume devoted to biological calci?cation, - sued by the CRC Press, Boca Raton (Florida) in 1992. Several basic aspects of the calci?cation process were analyzed in it by outstanding authors who had unquestioned competence in their respective research areas. Its main aim was that of giving readers access to a series of papers which, even though they discussed divergent aspects of biological calci?cations drawn from the study of systems as different as vertebrate skeletons and mollusks, in vitro cultures and unicellular organisms, ectopic calci?cation and urinary stones, provided elements permitting a coherent approach to a comprehensive view of the calci?cation process in biological tissues.

A Sea Change: The Exclusive Economic Zone and Governance Institutions for Living Marine Resources
A Sea Change in a Changing Sea The oceans, seas and coastal areas encompass over 70% of the earth’s surface. They are a critical driver of the earth’s hydrologic cycle and climate system, important for c- merce, transport, and tourism, a source of economically important living marine resources, minerals such as hydrocarbons, as well as new pharmaceutical compounds. The marine environment provides essential habitats for thousands of marine living 1 2 resources, which in turn contribute significantly to global food security, employment, 3 and trade. Overall, the sea’s contribution to human welfare, in terms of market and non-market resources and environmental services, has been estimated at US$21 trillion/year (Costanza, 2000). However, despite the importance of the ocean realm to humans, there is a growing sense that human impacts are destabilizing this system. Some experts believe that current fishing levels are approaching or exceeding the total 4 productivity of the ocean ecosystem (National Research Council, 1999).

The impact of biogeochemical processes on inorganic carbon dynamics and organic matter transformation are also discussed.
Links between geological processes, microbial activities & evolution of life : Microbes and geology
Microbial activities influence water-rock interaction processes and chemical transport between the major geochemical reservoirs and the formation/transformation of minerals and rocks, whereas geological processes and geochemical controls influence the microbial ecology in extreme environments. How biological activity influences geological processes and what role these processes played in the geological evolution of the Earth are fundamental questions.
Kinetics of Water-Rock Interaction
Systems at the surface of the Earth are continually responding to energy inputs derived from solar radiation or from the radiogenic heat in the interior. These energy inputs drive plate movements and erosion, exposing metastable mineral phases at the Earth’s surface. In addition, these energy fluxes are harvested and transformed by living organisms. As long as these processes persist, chemical disequilibrium at the Earth’s surface will be perpetuated. Chemical disequilibrium is also driven by human activities related to production of food, extraction of water and energy resources, and burial of wastes. To understand how the surface of the Earth will change over time, we must understand the rates at which reactions occur and the chemical feedbacks that relate these reactions across extreme temporal and spatial scales. This book addresses fundamental and applied questions concerning the rates of water-rock interactions driven by tectonic, climatic, and anthropogenic forcings.

Carbon in the Geobiosphere : Earth's outer shell
Carbon and carbon dioxide always played an important role in the geobiosphere that is part of the Earth’s outer shell and surface environment. The book’s eleven chapters cover the fundamentals of the biogeochemical behavior of carbon near the Earth’s surface, in the atmosphere, minerals, waters, air-sea exchange, and inorganic and biological processes fractionating the carbon isotopes, and its role in the evolution of inorganic and biogenic sediments, ocean water, the coupling to nutrient nitrogen and phosphorus cycles, and the future of the carbon cycle in the Anthropocene. This book is mainly a reference text for Earth and environmental scientists; it presents an overview of the origins and behavior of the carbon cycle and atmospheric carbon dioxide, and the human effects on them. The book can also be used for a one-semester course at an intermediate to advanced level addressing the behavior of the carbon and related cycles.
Biomineralization II : Mineralization Using Synthetic Polymers and Templates
In nature, biological organisms produce mineralized tissues such as bone, teeth, diatoms, and shells. Biomineralization is the sophisticated process of production of these inorganic minerals by living organisms. Construction of organic–inorganic hybrid materials with controlled mineralization analogous to those produced by nature has recently received much attention because it can aid in understanding the mechanisms of the biomineralization process and development of biomimetic materials processing. The biomineralization processes use aqueous solutions at temperatures below 100 ◦C and no toxic intermediates are produced in these systems. This series presents critical reviews of the present position and future trends in modern chemical research. The short and concise reports on chemistry are each written by world renowned experts. This series is still valid and useful after 5 or 10 years.
Biomineralization I : Crystallization and Self-Organization Process
