Scientific Interests and Goals:
We investigate the ecology of distinct phylogenetically defined piocoplancton populations (e.g. Flavobacteria, Gammaproteobacteria) in the marine water column. We are interested in the identity and abundance, but also in the role and fate of specific clades and their interactions with the living and non-living environment.
Within the BMBF-funded project “Microbial Interactions in Marine Systems” (MIMAS), the seasonal dynamics of the microbial community at the Long Term Ecological Research site Kabeltonne, Helgoland, was explored over a period of three years. Our focus was the bacterioplankton succession after the spring diatom bloom.
In collaboration with the Microbial Genomics Groups, the Alfred Wegener Institute, and the University of Greifswald automated FISH quantifications were combined with metagenome, metatranscriptome and metaproteome analyses. This yielded unprecedented insights in polysaccharide degradation and transporter profiles which suggested bottom-up regulation of distinct bacterial clades. We are currently investigating whether the succession patterns are deterministic rather than stochastic (Teeling et al., 2012).
