- Selection differentials were calculated combining data from plants of different elevations. In cases where elevation effect were significant (Figs. 1 and 2), additional analyses were performed for data from plants of the different elevations separately. Positive selection differentials indicate selection for larger values, while negative values indicate selection for smaller values of the trait. Significant responses are indicated by bolded p-value. n = number of pairs within each analysis
