Microbial Ecology

Head of the Module Marc LE ROMANCER (Associate Professor, UBO)
Type Optional
Number of hours 48
Learning outcomes To know and learn to recognize the diversity of microbial communities and their physiological characteristics; to understand the role of phototrophic and heterotrophic microorganisms and viruses in different compartments of marine ecosystem microbial communities, from the surface of the water column to deep marine sediments and hydrothermal vents.
Aims To learn different methodological approaches to analyze and understand the extent of the abundance and diversity of microbial communities; to discover their role in ecosystems of different marine environments through the study of the microbial loop and the ecological impact of viruses, from the open ocean to the hydrothermal vents.
Course content
  • Study and analysis techniques for the abundance and diversity of microbial bacteria, archaea and viruses
  • Role of microorganisms in the food web
  • Contribution to the functioning of the microbial loop in the water column
  • Factors regulating microbial communities in open environments
  • The deep ocean
  • Hydrothermal vents
  • The sub-Antarctic environment
  • Microbes and pathology in the aquatic environment
  • Viral abundance and diversity in the marine environment
  • Environmental impact of viruses in the ocean
Practicals: analysis of the abundance and diversity of microbial communities by molecular and culture approaches. Research, estimation of viral abundance and diversity by microscope techniques (epifluorescence and transmission electron microscopy).
Teaching methods Lectures + tutorials + laboratory practicals and boat trips to collect samples
