对新情况的行为反应往往各不相同，可以属于一套相关的行为。不同人格类型的特征行为（例如压力应对方式）在不同的环境和时间通常是一致的。在这里，我们比较的重复性和可靠性的探索行为之间的斑马鱼品系选择性繁殖显示对比的行为反应的压力，代表主动反应轴。具体来说，我们测量探索行为的个别鱼在开放的领域测试超过五个星期。我们量化了静止时间，平均游泳速度和鱼在中心区域所花费的时间。我们发现每种行为测量都有一些应变差异。静止时间是评估主动反应行为差异的最可重复和最可靠的指标。反应性斑马鱼一般表现出最高的可靠性和可重复性的探索行为相比，积极主动的斑马鱼和一个单独的野生捕获菌株。鉴于对一致个体差异的进化后果和近似机制的兴趣日益增加，继续研究不同的选择性压力如何影响压力应对方式的表达及其对动物行为一致性的影响将是重要的。
Behavioral responses to novel situations often vary and can belong to a suite of correlated behaviors. Characteristic behaviors of different personality types (e.g. stress coping styles) are generally consistent across contexts and time. Here, we compare the repeatability and reliability of exploratory behaviors between zebrafish strains selectively bred to display contrasting behavioral responses to stressors that represent the proactive-reactive axis. Specifically, we measure exploratory behavior of individual fish in an open field test over five weeks. We quantified the stationary time, average swimming speed and time spent by a fish in the center area. We found a number of strain differences for each behavioral measure. Stationary time was the most repeatable and reliable measure for assessing proactive-reactive behavioral differences. Reactive zebrafish generally showed the highest reliability and repeatability of exploratory behavior compared to proactive zebrafish and a separate wild caught strain. Given the increased interest in the evolutionary consequences and proximate mechanisms of consistent individual differences, it will be important to continue to investigate how different selective pressures may influence expression of stress coping styles and their effects on the consistency of an animal’s behavior.
