In spite of impressive advances in recent years, our present understanding of organic aerosol (OA) composition, physical and chemical properties, sources a...
Molecular ecology and metagenomics applied to the study of microbial biodiversity are changing our comprehension of the biosphere. An impressive diversity ...
A growing proportion of this stored information can be deciphered thanks to impressive developments in analytic techniques (cf. Birks, this volume). An ...
Abstract The emergence and evolution of life on our planet was possible because the sun provides energy to our biosphere. Indeed, all life forms need energ...
Future climate change may have considerable effects on the hydrologic cycle and temperature, with significant consequences for sea level, food production, world economy, health, and biodiversity. How and why does the natural climate syst...
Earth Systems: Processes and Issues is the ideal textbook for introductory courses in earth systems science and environmental science. Integrating the principles of the natural sciences, engineering, and economics as they pertain to the ...

This chapter highlights and explains the impressive story of the persistence of the Amazonian rainforest throughout the Cenozoic. Palaeoclimate and palaeoecological records suggest that the Amazon rainforest originated in the late Cretac...
Those of us who have been developing the concept of a marine microbial food web have believed for many years that Protozoa are major movers of energy and nutrients. Indeed, Vernadskii (1926) repeatedly referred to the special significanc...
Biominerals are generated by the subtle interaction of biological organization and mineral growth. They belong both to the living and the inanimate world a...
It is sometimes assumed that the rapidity of biogenesis on Earth suggests that life is common in the Universe. Here we critically examine the assumptions i...
Photo-oxidation of [Fe(H2O)6]2+ proceeds at λ < 300 nm with formation of a solvated electron. At pH > 6.5, however, the photochemistry is dominated by the...
The oxidative deposition of iron in the Banded iron-Formations can be quantitatively accounted for by direct abiotic photo-oxidation, by extrapolating from laboratory conditions and making reasonable assumptions about the early Earth and...
Under the influence of alkyl hydroxybenzene (C 6 -AHB) added to cell suspensions at concentrations of (1–5) × 10 –3 M, the cells of Saccharomyces cerevi...
Organic matter is preserved in unmetamorphosed and low-grade metamorphic pyrite and/or Mn-bearing black shales, pyrite-Mn stratiform ores, cherts and siliceous stromatolites of Proterozoic age in the Barrandian area of the Bohemian Massi...
Banded iron formations are rocks of sedimentary origin, formed 2-4 billion years ago. They consist of alternating layers of iron oxides and silicates. In the oxide layers the iron is often in the Festate while in the silicate layers the ...
Chemolithoautotrophic sulfur oxidizing bacteria (SOB) couple the oxidation of reduced sulfur compounds to the production of biomass. Their role in the cycl...
