Heritability and genetic correlations of personality traits in a wild population of yellow-bellied marmots (Marmota flaviventris).

摘要: Describing and quantifying animal personality is now an integral part of behavioural studies because individually distinctive behaviours have ecological evolutionary consequences. Yet, to fully understand how traits may respond selection, one must the underlying heritability genetic correlations between traits. Previous reported a moderate degree traits, but few these either been conducted in wild or estimated Estimating additive variance covariance crucial potential Enhanced environmental variation could reduce correlations, thus leading different predictions. We docility trap, sociability (mirror image stimulation), exploration activity two contexts (open-field mirror simulation experiments) population yellow-bellied marmots (Marmota flaviventris). both found nonzero also maternal, permanent environment year effects. Finally, we four phenotypic positive correlation open-field test sociability. tests MIS test.
