Polar and Alpine Microbiology Virtual Issue 2013


Most of the Earth's biosphere is characterized by low temperatures. These habitats span from the Arctic to the Antarctic, from high mountain-range environments to the deep ocean, and include permafrost soils, marine sediments, sea and glacial ice. Microorganisms, representing of all three domains of life, have successfully colonized these cold environments and there is thus considerable interest in understanding the adaptations and activities of these microorganisms, as well as the ecological interactions of communities active in these habitats. Global climate change is expected to affect polar ecosystems severely, with impacts on biogeochemical cycles and environmental change as well as feedback to climate.

In advance of the Fifth International Conference on Polar and Alpine Microbiology to be held September 9-12, 2013 in Big Sky, Montana (USA) this virtual issue of FEMS Microbiology Ecology brings you a selection of papers dedicated to Polar and Alpine Microbiology. This represents only a small selection of what we have published in recent years and for additional articles, please search the FEMS Microbiology Ecology back issues, including two thematic issues: Polar and Alpine Microbiology (November 2012) and Microorganisms in cold environments (February 2007). Please stayed tuned for the upcoming a special thematic issue on Microbes in Polar and Alpine Environments (expected spring 2014).
