WG Microorganisms and biogeochemical cycles
We study the structure and function of marine micro-organisms in the cycling of matter and in interactions with other organisms, both in natural environments and under controlled conditions.
- Investigating the structure and function of microbial communities (microalgae, bacteria, archaea, viruses) and their changes in the context of climate change and other anthropogenic impacts
- The role of microbial communities in nutrient cycling in coastal marine ecosystems
- Ecology of Harmful Algal Blooms
- Development of diversity indices for assessing the ecological status of the sea
- Understanding the functional ecology of phytoplankton species based on their functional traits
- Maintaining a long-term series of biological and chemical data to study changes and trends through statistical analysis and modelling
- Investigate genetic traits of ecologically important species (including HAB) and introduce new methods for environmental diagnostics
- Investigate interaction of microbes with planktonic organisms with emphasis on microbe-gelatinous plankton interactions and consequences
- Distribution and role of potential pathogens in coastal marine environments and development of new detection methods
- Response of microbes to anthropogenic impacts and various organic pollutants
- Geochemical and biological processes in hypersaline environments
- Integrative taxonomy of microalgae (light and electron microscopy, phylogenetic barcoding of individual strains, metabarcoding of phytoplankton communities)
- Determination of structure and function of microbial communities using NGS and state-of-the-art tools of bioinformatics and computational biology
- Cultivation, taxonomic identification and investigation of physiology and biochemistry of selected bacterial and microalgal strains from the culture collection at the MBP
- Microscopy-based analysis of microbial metabolic activities at the single cell level
- Measurement of primary and bacterial production using radiolabeled isotopes (14C, 3H)
