Mobile, electronic handheld guides offer the opportunity to improve a visitor’s experience by recommending exhibits of interest, and adapting the delivered content. ...

Contrary to classical population genetics theory, experiments demonstrate that fluctuating selection can protect a haploid polymorphism in the absence of frequency dependent effects on fitness. Using forward simulations with the Moran model, we confirm our analytical results showing that a fluctuating selection regime, with a mean selection coefficient of zero, promotes polymorphism. We find th...
