Localized coevolution between microbial predator and prey alters community-wide gene expression and ecosystem function

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.

Siderophores as an iron source for Prochlorococcus in deep chlorophyll maximum layers of the oligotrophic ocean

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.

Effects of phenotypic variation on consumer coexistence and prey community structure

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.

Strong selective environments determine evolutionary outcome in time-dependent fitness seascapes

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

Repeatable ecological dynamics govern response of experimental community to antibiotic pulse perturbation

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

Evolution in interacting species alters predator life history traits, behavior and morphology in experimental microbial communities

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.
