行为是动物基因组与其环境之间的关键接口。动物行为中可重复的个体差异已被广泛记录，但自然种群中个体行为差异的分子基础仍然很大程度上未知。在这里，我们对分子技术何时可能产生新的见解进行了批判性的回顾，并就如何以及在不同资源，系统和有机约束以及实验设计的情况下可用的最新工具是否合适提供了具体的指导。将分子遗传技术与其他策略结合起来研究行为的近端原因，为迅速扩展到新的探索途径提供了机会。这样的努力将使我们能够更好地理解可重复的个体行为差异是如何进化的，它们是如何表达的，以及如何在动物的自然种群中保持它们。
Behaviour is a key interface between an animal’s genome and its environment. Repeatable individual differences in behaviour have been extensively documented in animals, but the molecular underpinnings of behavioural variation among individuals within natural populations remain largely unknown. Here, we offer a critical review of when molecular techniques may yield new insights, and we provide specific guidance on how and whether the latest tools available are appropriate given different resources, system and organismal constraints, and experimental designs. Integrating molecular genetic techniques with other strategies to study the proximal causes of behaviour provides opportunities to expand rapidly into new avenues of exploration. Such endeavours will enable us to better understand how repeatable individual differences in behaviour have evolved, how they are expressed and how they can be maintained within natural populations of animals.
