Tempo and mode of genome evolution in a 50,000-generation experiment

The paper analyzes 264 genomes from 12 Escherichia coli populations over 50,000 generations to study genome evolution dynamics and finds that most fixed mutations are beneficial, with neutral mutations accumulating at a constant rate.

Competition between continuously evolving lineages in asexual populations

The paper develops a theoretical framework to model lineage interference in asexual populations, showing that beneficial mutations must exceed a critical threshold to fix, across all mutation-rate regimes.

Sustained fitness gains and variability in fitness trajectories in the long-term evolution experiment with Escherichia coli

The paper extends a previous study on Escherichia coli evolution, showing that fitness continues to increase over 60,000 generations with power-law dynamics and population-specific variability.

Modeling and quantifying frequency-dependent fitness in microbial populations with cross-feeding interactions

The paper develops a framework to measure frequency-dependent fitness in microbial populations with cross-feeding interactions using a Monod-type model and long-term evolution experiment data.
