|Module title||Life At The Limits: Geo-Ecology Of Extreme Environments|
|Module lecturer||Michał Jakubowicz, PhD|
|Lecturer position||Assistant Professor|
|Faculty||Faculty of Geographical and Geological Sciences|
Module aim (aims)
- acquiring the basin knowledge of ecology of extremophile organisms and communities, with special emphasis on the ecosystems based on chemosynthesis: hydrothermal vents, methane (cold) seeps and other reducing habitats, 'deep hot biosphere'
- understanding the controls on the development of 'life oases' based on chemical energy sources
- understanding the relationships between the organic and inorganic components of extreme environments
- ability to recognize ancient chemosynthesis-based ecosystems in the fossil record
Pre-requisites in terms of knowledge, skills and social competences (where relevant)
Basic knowledge in the field of geosciences
Week 1: Principal types and elements of extremophile ecosystems, with special emphasis on chemosynthesis-based communities
Week 2: Processes behind the chemosynthetic 'life oases': microbial oxidation of methane, sulphide, sulphate, iron and manganese
Week 3: Trophic structure of extremophile ecosystems; interactions between the metazoans and chemosynthetic microbes; the marvel of chemosymbiosis
Week 4: Interactions between the organic and inorganic components of chemosynthesis-based ecosystems: how the extreme environments shape their communities, and how the communities shape their extreme environments
Week 5: Geobiology of extreme ecosystems: the main types and characteristics of minerals forming around submarine springs
Week 6: Interpretation of extreme environments: palaeontological, petrological and geochemical characteristics of modern and fossil chemosynthesis-based ecosystems
Week 7: Fossil record of extreme environments
