Since 1.12.2008, the MPI Microbial Habitat group and the AWI Deep-Sea Research group form the Helmholtz - Max Planck Joint Research Group for Deep-Sea Ecology and Technology. Additional information on the work of the group situated at the AWI can be found here.
The microbial habitat describes the physical location and type of environment in which a population of microorganisms live. Hence, this research group studies the physical, chemical, geological hydrological, and biological characteristics of distinct microbial habitats. The goal of our research is to understand structure and change of microbial ecosystems, the formation of niches for microbial populations, and to investigate environmental dynamics and their consequences on the occurrence, biodiversity, and distribution of microbial populations.
The uniting topics to all researchers in the group is to obtain 1) “true” quantitative insight to ecosystem structure, dynamics, and biogeochemical fluxes, based on in situ measurements, and 2) insight into the related variations in microbial biodiversity on relevant spatial and temporal scales. The development of novel instrumentation for in situ studies of submarine ecosystems, ranging from coastal sands, reefs, continental margins, and polar waters to hydrothermal vents, enables us in collaboration with the Microsensor group to improve the quantification of transport and reaction, which are dominant factors structuring microbial habitats.
Furthermore, we link our in situ biogeochemistry and biodiversity studies closely to the investigation of microbial function in the respective habitats, in collaboration with the department of Microbiology and Molecular Ecology.
