Microbial Systems Ecology

 Microbial Systems Ecology

Microorganisms play crucial roles in ecosystem functioning and a major goal in microbial ecology is linking specific microbial populations to environmental processes, such as those in biogeochemical cycling. Some of the key challenges are in assessing the links between microbial diversity, the interactions among complex communities and trophic levels, and their relevance to ecosystem functions. Complementary approaches, including cultivation-independent molecular techniques, physiological characterization of cultivated microorganisms and conceptual theoretical approaches, are providing the essential understanding of these links and biological interactions. This thematic issue highlights some recent papers that have appeared in FEMS Microbiology Ecology to coincide with the sponsored session on Microbial Systems Ecology at the 2013 FEMS Congress.
