塑料反应可能对发生在不可预测环境中的生物、迁徙物种和占据新环境的生物具有适应性意义。斑马鱼(Danio Rerio)生活在各种各样的栖息地和环境中，这些栖息地和环境在季节和栖息地之间频繁波动。我们预计野生鱼类种群的行为将比在传统实验室和孵化场环境中饲养的鱼类更灵活。我们测量了2个野生(U和Pn)斑马鱼种群和1个实验室饲养(SH)斑马鱼种群在四种不同水流和植被条件下的三种行为特征。我们发现，可塑性程度随行为类型的不同而不同，也随人群的不同而不同。总体而言，植被增加了攻击性，水流减少了干扰后取食的潜伏期，但模式取决于种群。例如，虽然野生U鱼在植被和/或流动的栖息地受到干扰后更容易摄食，但来自野生Pn种群和实验室饲养的SH品系的鱼在不同环境条件下的觅食差异很小。当在有植被的竞技场进行测试时，所有三个种群的斑马鱼都更具攻击性。相反，尽管种群间的浅滩距离存在差异，但种群内环境条件下浅滩距离的变化并不显著。这些结果表明，斑马鱼的觅食和攻击性都比浅滩距离更具可塑性和受直接环境的影响，这可能有更强的遗传基础。我们的发现指出了影响这些特征表达的不同潜在机制，并值得进一步研究。
Plastic responses can have adaptive significance for organisms occurring in unpredictable environments, migratory species and organisms occupying novel environments. Zebrafish (Danio rerio) occur in a wide range of habitats and environments that fluctuate frequently across seasons and habitats. We expect wild populations of fish to be behaviorally more flexible than fish reared in conventional laboratory and hatchery environments. We measured three behavioral traits among 2 wild (U and PN) and 1 laboratory bred (SH) zebrafish populations in four environments differing in water flow and vegetation regimes. We found that the degree of plasticity varied with the type of behavior and also among populations. In general, vegetation increased aggression and water flow decreased latency to feed after a disturbance, but the patterns were population dependent. For example, while wild U fish fed more readily after a disturbance in vegetated and/or flowing habitats, fish from the wild PN population and lab-reared SH strain showed little variation in foraging across different environmental conditions. Zebrafish from all the three populations were more aggressive when tested in an arena with vegetation. In contrast, while there was an inter- population difference in shoaling distances, variation in shoaling distance across environmental conditions within populations was not significant. These results suggest that both foraging and aggression in zebrafish are more plastic and influenced by immediate context than is shoaling distance, which may have a stronger genetic basis. Our findings point to different underlying mechanisms influencing the expression of these traits and warrants further investigations.
