Oceans and seas represent the largest part of the Earth’s biosphere and marine microbes are the most abundant group of organisms, capable of growing in all marine habitats. Microbes are the key players in marine food webs and are involved in all biogeochemical cycles. The central focus of our research is to study the impacts of variable supply regimes of different inorganic and organic matter on the function and diversity of the microbial communities, mainly Bacteria and Achaea, in shallow enclosed coastal marine ecosystems. Oceanographic properties are strongly affected by water mass exchange, river inflow and meteorological conditions, which influence the microbial community composition and function.
Our recent and ongoing projects are especially focusing on the microbial community response to changes of physiochemical environmental parameters, phytoplankton blooms, massive gelatinous zooplankton outbreaks and accumulations of organic matter (i.e. marine snow, macroaggregates).Furthermore, we are investigating the response of marine microbial communities to different source of anthropogenic pollutants.
