“…For instance, Sih et al 40 suggested that individual variation in inherently stable and/or labile traits that are linked to individual state (e.g., sex, age, physiological state) might play important role in the emergence of behavioural consistencies. To date, studies testing thermoregulatory strategies in the context of behavioural syndromes are rather scarce (see also 41 ). Goulet et al 32 , 42 and Michelangeli et al 35 proposed that organisms can be aligned along a ‘hot–cold’ axis: they showed that delicate skinks ( Lampropholis delicata ) with a ‘hot’ thermal type are bolder, having higher maximal sprint speed, perform better at higher optimal temperatures and within a narrower range compared to ‘cold’ type peers.…”

The study of consistent between-individual behavioural variation in single (animal personality) and across two or more behavioural traits (behavioural syndrome) is a central topic of behavioural ecology. Besides behavioural type (individual mean behaviour), behavioural predictability (environment-independent within-individual behavioural variation) is now also seen as an important component of individual behavioural strategy. Research focus is still on the ‘Big Five’ traits (activity, exploration, risk-taking, sociability and aggression), but another prime candidate to integrate to the personality framework is behavioural thermoregulation in small-bodied poikilotherms. Here, we found animal personality in thermoregulatory strategy (selected body temperature, voluntary thermal maximum, setpoint range) and ‘classic’ behavioural traits (activity, sheltering, risk-taking) in common lizards (Zootoca vivipara). Individual state did not explain the between-individual variation. There was a positive behavioural type—behavioural predictability correlation in selected body temperature. Besides an activity—risk-taking syndrome, we also found a risk-taking—selected body temperature syndrome. Our results suggest that animal personality and behavioural syndrome are present in common lizards, both including thermoregulatory and ‘classic’ behavioural traits, and selecting high body temperature with high predictability is part of the risk-prone behavioural strategy. We propose that thermoregulatory behaviour should be considered with equal weight to the ‘classic’ traits in animal personality studies of poikilotherms employing active behavioural thermoregulation.
