Lay summary
While the biodiversity ecosystem functiong (BEF) debate has considerably advanced macroorganismic and theoretical ecology, a central question remains whether (and how) the BEF coupling applies to the microbial world. This is of immense ecological and societal relevance because of the central role of microorganisms in natural and engineered ecosystems. In nature bacteria predominantly exist as biofilms, i.e. as sessile communities on various biotic and abiotic surfaces. The ability to form biofilms is probably one of the most remarkable characteristics of bacteria and in many habitats microbial activity is mainly associated with biofilms. Work that has accumulated over the past ten years showed that bacterial cell-to-cell communication plays an important role in the formation of biofilms. Within this project we analyze the effects of bacterial signalling on the architecture and composition of biofilms. Furthermore, the importance of communication for the ability of bacteria to invade and persist in biofilms is investigated.
