为了检查行为综合征是否存在于溯河产卵种群的青少年三棘鱼Gasterosteus aculeatus中，个体反复暴露于各种条件下以评估行为一致性并确定是否发生害羞大胆综合征。在新环境中的探索程度与在所有其他测试条件下的大胆程度呈正相关。在所有情况下，觅食，捕食者检查和浅滩的活动水平被发现是可重复的，而其他行为，如延迟响应出现更多的塑料。与先前对淡水种群的研究相比，在不同环境中发现了行为相关性的相似性和差异性。刺肌这表明，选择压力可能会因个体发育和环境而异。(C)2011作者鱼类生物学杂志（C）2011不列颠群岛渔业协会
To examine if a behavioural syndrome is present in juvenile three-spined stickleback Gasterosteus aculeatus from anadromous populations, individuals were repeatedly exposed to a variety of conditions to assess behavioural consistency and determine if a shyness-boldness syndrome occurred. The degree of exploration in a novel environment was positively correlated with boldness in all other test conditions. Activity level in all contexts, foraging, predator inspection and shoaling were found to be repeatable while other behaviours such as latency to respond appeared more plastic. Both similarities and differences were found for behavioural correlations within and across contexts when compared to prior studies on freshwater populations of G. aculeatus. This suggests that selection pressures may vary across ontogeny and environments. (C) 2011 The Authors Journal of Fish Biology (C) 2011 The Fisheries Society of the British Isles
