社交网络分析捕获的社会关系的数量和质量可能会产生重大的健康影响。各种研究表明，社会行为的个体差异可能是由于发育压力的差异造成的。然而，这些发展差异是否会转化为社交网络地位的一致差异尚不清楚。我们通过完全平衡的设计，实验性地提高了斑胸草雀雏鸟体内鸟类应激激素皮质酮 (CORT) 的水平。在达到营养独立后，我们将雏鸡及其家人放入两个自由飞行的房间，在那里我们使用无源集成应答器标签测量了五周内的日常社交网络。发育压力对社会行为有显着影响：尽管 CORT 雏鸡具有相似的觅食模式，但与对照组雏鸡相比，它们与父母的联系较弱。相反，CORT 雏鸟会与更多的同伴一起觅食，并且不会那么挑剔，从而在网络中占据更中心的位置。这些发现强调了考虑发展历史以了解群居物种社会组织驱动因素的重要性。
The quantity and quality of social relationships, as captured by social network analysis, can have major fitness consequences. Various studies have shown that individual differences in social behaviour can be due to variation in exposure to developmental stress. However, whether these developmental differences translate to consistent differences in social network position is not known. We experimentally increased levels of the avian stress hormone corticosterone (CORT) in nestling zebra finches in a fully balanced design. Upon reaching nutritional independence, we released chicks and their families into two free-flying rooms, where we measured daily social networks over five weeks using passive integrated transponder tags. Developmental stress had a significant effect on social behaviour: despite having similar foraging patterns, CORT chicks had weaker associations to their parents than control chicks. Instead, CORT chicks foraged with a greater number of flock mates and were less choosy with whom they foraged, resulting in more central network positions. These findings highlight the importance of taking developmental history into account to understand the drivers of social organization in gregarious species.
