  1. The pond name, map ID corresponding to Figure 1, and year of collection are given for each population, along with the regression terms (β/γ), estimated selection differential for each term, its standard error (SE), t-statistic and probability of rejecting the null hypothesis that the estimated differential is zero. For quadratic regressions, positive selection differentials signify disruptive selection and the quadratic regression coefficient is doubled to calculate the quadratic selection differential (γ) and the associated standard error (SE) is also doubled. Bolding signifies statistical significance.
