Marine microbial ecology: from genomes to biomes

Have you ever wondered why the ocean is blue? How life evolved? How elements cycle in the sea? Or maybe, why the ocean buffers our human activities? This course aims to tackle these questions and much more. The course will cover broadly aquatic microbial diversity and the role of microbes in the environment.

This course is designed to cover broadly aquatic microbial diversity and role of microbes in the environment. Environments include aquatic, benthic (sediments), and microbiomes. Microbial populations include representatives from the three domains of life: Archaea, Bacteria, Eukarya. The diverse nature of microbial populations will be studied and includes the morphology, genetic, and metabolic diversity. Additionally, a review of both classical and modern methods utilized in studying aquatic microbial ecology will be presented in case study examples and laboratory exercises. An emphasis on understanding the limitations, caveats, and necessary controls for methods will be covered.

Both theory and practical exercises cover the most recent findings of the field while also providing practical hands on experience and training in classic and modern approaches.

  • Schedule

    The schedule will be available no later than one month before the start of the course. We do not recommend print-outs as changes can occur. At the start of the course, your department will advise where you can find your schedule during the course.
  • Course literature

    Note that the course literature can be changed up to two months before the start of the course.

    There is no textbook for the course. Suggested and required readings will be listed on the course website on Athena and should be read prior to the lecture. Other suggested readings include the online book: Gasol and Kirchman 2018 Microbial Ecology of the Oceans 3rd Edition.
