Treatment refers to whether populations coevolved with N. whitei or not, and size refers to population size (i.e. small vs. large population size). The analysis was performed separately for males and females. Only fixed effects are shown; the random factor 'experimental population' never had a significant effect. Significant P-values are highlighted in bold.
