2204por Moulherat, Sylvain, Chaine, Alexis, Mangin, Alain, Aubret, Fabien, Sinervo, Barry, Clobert, Jean“…Our results show that both genetic mechanisms can maintain polymorphism depending on population demographic characteristics but that plasticity can enhance the likelihood that polymorphism is maintained relative to dominance. Time series analysis on simulation outcomes show that the RPS game is mostly driven by a single strategy, but the importance of this strategy on long term dynamics is stronger when gene expression shows dominance rather than plasticity.…”

We use time series analysis to measure the extent to which the observed likelihood of death among women aged 20–24 differs from statistically expected values when the number of older women grows or declines. …”
