Dr Christa Schleper, professor, Archaea Ecology and Evolution, University of Vienna, Austria Short biography: Christa Schleper is professor for Microbiology and Genetics at the Faculty for Life Sciences of the University of Vienna, where she holds the chair of the Division of Archaea Biology and Ecogenomics since 2007. She has studied Biology in Aachen und Konstanz, obtained her PhD at the Max-Planck-Institute for Biochemistry in Munich and was a postdoc for three years in California (Univ. of Califorania Sta. Barbara und Caltech, Pasadena), before she started as an assistant Professor in Darmstadt Technical University. She was appointed as full professor in 2004 at the Univ. of Bergen Norway and moved to Vienna in 2007. Christa Schleper is elected member of the American and European Academies of Microbiology and of the Austrian Academy of Sciences. Her major research interests are the ecology and evolution of Archaea in moderate environments. |

Abstract:
Archaea are microorganisms that emerged on this planet roughly 3.5 billion years ago as one of two primary lineages of life beside Bacteria. They are often associated with extreme environments, because most of the described organisms stem from hot springs or hypersaline environments. However, two functional guilds of archaea are ecologically widespread and have successfully radiated into moderate marine and terrestrial environments. They are anaerobic methanogens and aerobic ammonia oxidizers. Both groups occupy important parts in the global carbon and nitrogen cycles and contribute to greenhouse gas production in the oceans and soils. In this talk I will give an update about newest findings of the ecology and diversity of both groups, and discuss their potential environmental impacts as well as controversial findings.
