Predicting the composition and function of microbial communities in a
given habitat is a major aspiration in microbiome biology. To realize
this goal, it is critical to identify which features of microbial
communities are reproducible and predictable, which are not, and why. We
address these questions by studying the assembly of hundreds of
microbial communities in simple replicate habitats and connecting the
experiments with modeling. I will first present recent work where we
show that microbial community assembly in glucose-limited habitats is
generally reproducible and convergent at higher levels of taxonomic
community organization and reflects an emergent metabolic
self-organization between different functional groups whose ratios can
be quantitatively explained with simple models. I will then show that in
mixed nutrient environments, there are non-trivial regularities in how
nutrients interact to shape the assembly of microbial communities that
reflect generic patterns of nutrient dominance at higher levels of
community organization.
