Abstract:
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.
摘要:
研究单个(动物人格)和两个或多个行为特征(行为综合征)的个体间一致的行为差异是行为生态学的中心主题。除了行为类型(个人平均行为),行为可预测性(与环境无关的个体内部行为变化)现在也被视为个人行为策略的重要组成部分。研究重点仍然是“五大特征”(活动,探索,冒险,社交能力和攻击性),但是整合到人格框架中的另一个主要候选人是小体格polikilotherms的行为体温调节。这里,我们在体温调节策略中发现了动物的个性(选定的体温,自愿性热最大值,设定值范围)和“经典”行为特征(活动,庇护,冒险)在普通蜥蜴(Zootocavivipara)中。个体状态不能解释个体间的变异。在选定的体温中存在正的行为类型-行为可预测性相关性。除了活动冒险综合征,我们还发现了一种选择冒险的体温综合征.我们的结果表明,动物人格和行为综合征存在于普通蜥蜴中,包括体温调节和经典行为特征,选择具有高可预测性的高体温是容易发生风险的行为策略的一部分。我们建议,在采用主动行为体温调节的动物人格研究中,应将体温调节行为与“经典”特征同等重要。
