Increasing melanism along a latitudinal gradient in a widespread amphibian: local adaptation, ontogenic or environmental plasticity?

Table 3 Fixed effect estimates for degree of melanism in juvenile common frogs reared in common garden

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.
