Data for: Fast adjustment of POLS to food quality

The pace-of-life syndrome hypothesis provides a framework for the adaptive integration of behaviour, physiology and life history at between and within species. It suggests that behaviours involving a risk of death or injury should co-vary with a higher allocation to fast reproduction. Empirical support for this hypothesis is mixed, presumably because important influencing factors such as environmental variation, are usually neglected. By experimentally manipulating the food quality of wild mice living under semi-natural conditions for three generations, we show that individuals adjust their life history strategies and risk-taking behaviours as well as trait covariation (Nindividuals = 1442). These phenotypic differences are correlated to differences in transcriptomic gene expression of primarily metabolic processes in the liver while no changes in gene frequencies occurred. Our discussion emphasizes the need to integrate the role of environmental conditions and phenotypic plasticity in ...
