Autumn. This is a course with limited capacity
The subject of this course is the ecological interactions between microorganisms. Special attention is given to the relationships between the microbial food web, biodiversity, the physical/chemical environment (CO2, light, micro/macro-nutrients), and biogeochemical element cycles in the ocean. An introduction is given to the use of simple mathematical models in the analysis of such relationships. The relationship between bacterial physiology and the structure of anaerobic marine ecosystems, and the role of microbial evolution in global biogeochemical cycles are treated. Basic methods in marine microbial ecology are used in an experimentally oriented semester exercise. This includes selected molecular methods for the study of microbial communities (PCR, DGGE, and PFGE). Documented knowledge in microbiology is needed.
