Carbon use efficiency of microbial communities: stoichiometry, methodology and modelling.

abstract：:Intraspecific variation is at the core of evolutionary theory, and yet, from an ecological perspective, we have few robust expectations for how this variation should affect the dynamics of large communities. Here, by adapting an approach from evolutionary game theory, we show that the incorporation of phenotypic varia...
