Fixed effect estimates for degree of melanism in juvenile common frogs reared in common garden

			95% HPDI
Effect	Estimate	SE	Lower	Upper
Intercept	0.230	0.177	-0.136	0.569
Snout-vent length	-0.005	0.008	-0.021	0.013
Population	0.167	0.066	0.041	0.298
Temperature	0.092	0.030	0.027	0.146

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.
