The pace‐of‐life syndrome hypothesis (POLS) represents an attractive theoretical framework suggesting that physiological and behavioural traits have evolved together with environmental conditions and life‐history strategies. POLS predicts that metabolic differences covary with behavioural variation such that high metabolic rate is associated with risk‐prone behaviour and a faster pace‐of‐life, whereas a low metabolic rate is associated with risk‐averse behaviour and a slower pace‐of‐life. We tested the POLS hypothesis in captive European Pied Flycatchers during their first year by examining the relationship between explorative behaviour and basal metabolic rate. Our results are inconsistent with POLS. The positive association of explorative behaviour with basal metabolic rate was not recovered for either sex, possibly due to foraging conditions in the aviaries where control and trial groups were fed twice a day, the birds' young age, developmental plasticity, or a non‐existent syndrome.

在欧洲的捕蝇Fi（Ficedula hypoleuca）中，探索行为与代谢无关

生活节奏综合症假说（POLS）代表了一个有吸引力的理论框架，表明生理和行为特征已经随着环境条件和生活史策略一起发展。POLS预测，代谢差异与行为差异有关，例如高代谢率与易发风险行为和较快的生活节奏相关，而低代谢率与风险厌恶行为和较慢的生活节奏相关。 。我们通过研究探索行为与基础代谢率之间的关系，在圈养的欧洲斑Pi捕捞的第一年中检验了POLS假设。我们的结果与POLS不一致。男女性别均未恢复探索性行为与基础代谢率的正相关关系，
