The paper examines how coevolution between a bacterial prey and its ciliate predator in a synthetic microbial community affects community-wide gene expression and ecosystem function.

The paper shows that Prochlorococcus in iron-depleted regions uses siderophores for iron uptake, with this trait more common in the North Pacific than the North Atlantic.

The paper manipulates intraspecific trait diversity in ciliates and nematodes to show that trait variation can invert competitive hierarchies and lead to competitive exclusion through foraging traits and cascading effects on prey communities.

This study shows that strong selective agents drive evolutionary outcomes in time-dependent fitness seascapes, with implications for predicting and mitigating drug resistance.

The paper studies how antibiotic pulses affect microbial communities, finding repeatable responses driven by species traits and immigration, alongside rapid within-species evolution.

This study shows that predator evolution in microbial communities alters morphology and behavior but not growth on ancestral prey, highlighting trait-specific evolutionary responses in co-evolving systems.
