The paper shows that hydrodynamic flow in the gut reduces the fixation probability of beneficial mutants but speeds up their invasion.

The paper shows environment heterogeneity can amplify natural selection and speed up mutant fixation in graph-structured populations, depending on migration rates and mutant fitness advantages.

The paper shows spatial structure in bacterial populations increases the probability of evolutionary rescue by antibiotic resistance through enhanced fixation of resistant mutants in small subpopulations.
