This study shows that genetic drift strength evolves over 50,000 generations in E. coli populations, with one population showing significantly stronger drift due to increased stochasticity.

The paper tests the assumption of constant fitness effects in microbial populations and finds frequency-dependent effects are common, with negative frequency dependence and non-transitive fitness outcomes.

The paper shows that asynchronous abundance fluctuations can cause large genotype frequency changes in microbial populations, distinct from genetic drift.
