一致的个体行为差异（即动物个性）和行为可塑性之间的相互作用最近引起了越来越多的兴趣。我们使用澳大利亚雄性田蟋蟀（Teleogryllus oceanicus）通过实验操纵测量期间的统治地位来研究统治地位如何影响不同人格特征（即大胆、探索和活动）的一致性和可塑性。我们发现，当受到社会挑战时，处于从属地位的统治者会改变自己的行为，变得不那么大胆、探索和活跃，而成为统治者的下属则变得更大胆、更具探索性和更积极。支配地位没有变化的个体不会改变他们的行为。主导地位的变化降低了探索和活动的假定人格特征的可重复性，但不影响大胆的可重复性。此外，支配地位的变化会影响某些人格特征之间的相关性，但不会影响其他人格特征之间的相关性。最后，呼叫行为与当前和未来的主导地位和探索倾向有关。我们讨论了我们的研究结果更广泛的进化和生态影响，并建议在研究行为综合症以及动物性格与行为可塑性之间的相互作用时应考虑社会地位的变化。
The interplay between consistent individual differences in behavior (i.e., animal personality) and behavioral plasticity has recently attracted increased interest. We used male Australian field crickets (Teleogryllus oceanicus) to investigate how dominance status influences the consistency and plasticity of different personality traits, namely boldness, exploration, and activity, by experimentally manipulating dominance status between measuring sessions. We found that dominants that became subordinate when socially challenged, shifted their behavior, becoming less bold, explorative, and active, whereas subordinates that became dominant, became bolder, more explorative, and more active. Individuals that experienced no change in dominance status did not alter their behavior. Changes in dominance status reduced the repeatability of the putative personality traits of exploration and activity while not affecting the repeatability of boldness. Moreover, changes in dominance status affected the presence of correlations between some personality traits, but not others. Finally, calling behavior was related to current and future dominance and explorative tendencies. We discuss the broader evolutionary and ecological implications of our findings and propose that changes in social status should be considered when investigating behavioral syndromes and the interplay between animal personality and behavioral plasticity.
