متن کاملArchaea in biogeochemical cycles.
Archaea constitute a considerable fraction of the microbial biomass on Earth. Like Bacteria they have evolved a variety of energy metabolisms using organic and/or inorganic electron donors and acceptors, and many of them are able to fix carbon from inorganic sources. Archaea thus play crucial roles in the Earth's global geochemical cycles and influence greenhouse gas emissions. Methanogenesis a...
متن کاملResponses and feedbacks of coupled biogeochemical cycles to climate change: examples from terrestrial ecosystems
© The Ecological Society of America www.frontiersinecology.org I an era of extensive environmental change, human activity – particularly the harvest of resources for food, fiber, and fuel – is substantially altering Earth’s climate and its element cycles (Vitousek et al. 1997; Figure 1). The need for energy to support economic growth has increased atmospheric carbon dioxide (CO2) concentrations...
متن کاملIntroduction to the Biogeochemical Cycling of Arsenic
Although arsenic is highly toxic to humans, and indeed most other forms of life, some microorganisms have evolved to tolerate relatively high concentrations of the metalloid, while specialist examples even thrive on the element, using it as a source of energy for growth. This surprising array of microbial processes, together with inorganic and physical processes, constitutes the global arsenic ...
