Abstract
Rhizosphere carbon flow is central to the functioning of grassland ecosystems but there is virtually no information on the relationship between the processes involved in  carbon flow and the diversity, community structure and resilience of the microbial populations mediating these processes. This project aims to assess rhizosphere carbon flow following input of a 13C pulse and simultaneously to assess changes in microbial diversity using analysis of 13C in phospholipid fatty acids and stable isotope probing, combined with established molecular ecology techniques, including cloning and sequencing of 16S and 18S rRNA genes and denaturing gradient gel electrophoresis. Integration of the different approaches for analysis of ecosystem function and microbial diversity will determine whether rhizosphere carbon flow drivers diversity.
