Low heritabilities, but genetic and maternal correlations between red squirrel behaviours

摘要: Consistent individual differences in behaviour, and behavioural correlations within across contexts, are referred to as animal personalities. These patterns of variation have been identified many taxa likely important ecological evolutionary consequences. Despite their importance, genetic environmental sources personalities rarely characterized wild populations. We used a Bayesian model approach estimate parameters for aggression, activity docility North American red squirrels (Tamiasciurus hudsonicus). found support low heritabilities (0.08-0.12), cohort effects (0.07- 0.09), well moderate maternal (0.07-0.15) permanent (0.08-0.16). Finally, we evidence substantial positive correlation (0.68) (0.58) between aggression providing genetically based squirrels. results provide the presence heritable squirrel but also emphasize role other variation, including effects, shaping covariation traits.
