Maternal diet affects juvenile Carpetan rock lizard performance and personality

Differences in both stable and labile state variables are known to affect the emergence and maintenance of consistent inter-individual behavioural variation (animal personality or behavioural syndrome), especially when experienced early in life. Variation in environmental conditions experienced by gestating mothers (viz. non-genetic maternal effects) are known to have significant impact on offspring condition and behaviour, yet, their effect on behavioural consistency is not clear. Here, by applying an orthogonal experimental design, we aimed to study if increased vitamin D3 content in maternal diet during gestation (vitamin-supplemented vs. vitamin control treatments) combined with corticosterone treatment (corticosterone-treated vs. corticosterone control treatments) applied on freshly hatched juveniles had an effect on individual state and behavioural consistency of juvenile Carpetan rock lizards (Iberolacerta cyreni). We tested the effect of our treatments on (i) climbing speed and ...

已知稳定与不稳定状态变量的差异会影响一致的个体间行为变异（动物性格（animal personality）或行为综合征（behavioural syndrome））的产生与维持，尤其当此类影响发生于生命早期时。妊娠母体所经历的环境条件变异（即非遗传母体效应），已被证实对子代状态与行为具有显著影响，但其对行为一致性的作用尚不明确。本研究采用正交实验设计，旨在探究妊娠期母体日粮中维生素D3（vitamin D3）含量提升（维生素补充组与维生素对照组），结合刚孵化幼体施加的皮质酮（corticosterone）处理（皮质酮处理组与皮质酮对照组），是否会对幼年卡珀坦岩蜥（Iberolacerta cyreni）的个体状态及行为一致性产生影响。我们测试了上述处理对（i）攀爬速度及……
