We are developing growth-based techniques to assess the ecology of fungi and bacteria, focusing on their contribution to carbon (C) cycling, and synthesize this into an understanding of growth efficiencies of soil microorganisms. This work will be pursued in four stages:
The methodological and conceptual core of this research, on the growth of soil microorganisms and the functional relevance of them for ecosystem services, is complementary to many of ongoing efforts at Lund University, not least the BECC and LUCCI networks. We will pursue cross-disciplinary and collaborative research efforts in this milieu, where the growth of the soil microbial community and their contribution to the C cycle can be integrated into many of these research frontiers, including e.g. C and N modeling work.
