The impact of resource supply on microbial community dynamics is rarely treated explicitly in research into the control and optimization of natural and synthetic microbial communities. Using simulations, we show that compositional overlap between microbial communities decays rapidly with a change in the frequency of resource pulsing, particularly in the presence of a metabolic trade-off in resource affinity and maximum growth rate. We conclude that resource supply dynamics should be considered both a constraint and a tuning mechanism in microbial community optimization.

"Similar papers" are the closest papers from that journal in the model's embedding space. They show what the match is built on, but the ranking comes mostly from a classifier over the whole training set, not from these examples alone.
