AbstractLarge stochastic population abundance fluctuations are ubiquitous across the tree of life, impacting the predictability and outcomes of population dynamics. It is generally thought that abundance fluctuations with a Taylor’s law exponent of two do not strongly impact evolution. However, we argue that such abundance fluctuations can lead to substantial genotype frequency fluctuations if different genotypes in a population experience these fluctuations asynchronously.

AbstractLarge stochastic population abundance fluctuations are ubiquitous across the tree of life, impacting the predictability of population dynamics and influencing eco-evolutionary outcomes. It has generally been thought that these abundance fluctuations do not strongly impact evolution, as the relative frequencies of alleles in the population will be unaffected if the abundance of all alleles fluctuate in unison.
