The data was arcsine transformed. The model was a linear mixed model incorporating family as a random effect. There were two temperature treatments, 'Warm' (used as a reference) and 'Cold', and two populations, 'North' = Björkliden (68°24'N; used as a reference) and 'South' = Tvedöra (55°42'N). SE = standard error, 95% HPDI = highest posterior density interval.
