Beyond the (geometric) mean: stochastic models undermine deterministic predictions of bet hedger evolution

This paper shows that stochastic models can change the evolutionary outcome of bet hedging compared to deterministic predictions, finding sign inversion depending on population size.

Sign inversion in selection on ploidy

This study shows that selection on ploidy can change sign with population size in non-equilibrium asexual populations due to indirect selection effects.

When good mutations go bad: how population size can change the direction of natural selection

The paper shows that mutations can change their selective effect direction depending on population size, challenging classical evolutionary theory.

Selection on mutators is not frequency-dependent

This paper shows that selection on mutator mutations in asexual populations is not frequency-dependent, challenging the common intuition about their evolutionary fate.

Sign of selection on mutation rate modifiers depends on population size

The paper shows that mutator alleles, which increase mutation rates, are favored by indirect selection in large populations but disfavored in smaller ones, demonstrating sign inversion in their selective effect.
