This paper develops a method to estimate genetic drift in SARS-CoV-2 transmission using lineage frequency time series and applies it to genomic data from England, finding consistently higher genetic drift than expected.

The paper shows that two-ecotype microbial communities can rediversify into two ecotypes after isolation, with similar patterns despite evolutionary time, but with differences in growth traits and transcriptional states.

The paper quantifies the adaptive potential of a bacterial community by measuring gene knockout fitness effects across different genetic backgrounds and ecological conditions.
