Neither pulled nor pushed: Genetic drift and front wandering uncover a new class of reaction-diffusion waves

The paper identifies a new class of reaction-diffusion waves, called semi-pushed waves, which exhibit properties of both pulled and pushed waves, with unique fluctuation behavior.

Allele Surfing Promotes Microbial Adaptation from Standing Variation

The paper shows that allele surfing in microbial range expansions increases mean fitness by promoting soft selective sweeps from standing variation, enhancing adaptation rates per biomass.

Excess of mutational jackpot events in growing populations due to gene surfing

The paper shows that mutational jackpot events are more common in spatially structured populations due to gene surfing, increasing the risk of drug resistance and evolutionary outcomes.

Self-driven jamming in growing microbial populations

The paper investigates self-driven jamming in microbial populations, showing it leads to large mechanical pressures that affect growth and microenvironment integrity.
