这里介绍的工作旨在了解鸟类性格类型的本质、后生和功能（这里称为行为特征），重点是一种野生鸟类，大山雀（Parus major）。双向选择的探索线显示出广泛的社会和非社会行为差异，以及生理参数的一些差异。这些特征的直线差异及其关系显示出显著的时间一致性。研究结果显示，大山雀和啮齿动物模型之间有着惊人的相似性，这表明了行为特征组织的基本原则。讨论了这一原则的性质以及它是否是多维的。然而，与鸡模型的相似性不太清楚，这表明在推广时需要谨慎。讨论了大山雀行为特征的表观发生。通过复制和回交的选择实验揭示了强大的遗传基础，并提出了母系效应的影响。个体发生操作表明有很强的发育可塑性，表明对当前环境的适应性调整。他们还表明，属于同一轮廓的行为特征可以变得不耦合。最后，总结了野生大山雀不同性格的几个适合度参数的野外数据。这些数据表明，选择压力在时间和空间上的变化以及分类交配是在同一种群中维持不同行为特征的合理机制。(C) 2004 Elsevier Ltd.版权所有。
The work presented here aims at understanding the nature, epigenesis and function of personality types (here called behavioral profiles) in birds, focusing on a wild bird species, the great tit (Parus major). Lines bidirectionally selected for exploration show a wide array of social and non-social behavioral differences, and also some differences in physiological parameters. Line differences in these characteristics and their relationships show significant temporal consistency. The results show a surprising similarity between the great tit and a rodent model, suggesting a fundamental principle in the organization of behavioral profiles. The nature of this principle and whether or not it is multidimensional is discussed. However, the similarity with a chicken model is less clear, which points to some caution for generalization. The epigenesis of great tit behavioral profiles is discussed. Selection experiments with replication and backcrosses reveal a strong genetic basis, and suggest an influence of maternal effects. Ontogenetic manipulations indicate strong developmental plasticity, suggesting adaptive adjustment to prevailing environmental circumstances. They also show that behavioral characteristics belonging to the same profile can become uncoupled. Finally, field data on several fitness parameters of the different personalities in wild great tits are summarized. These data suggest that variation in selection pressure in time and space and assortative mating are plausible mechanisms accounting for the maintenance of different behavioral profiles within the same population.
