一致的养育子女的个体差异是普遍存在的;然而，我们对为什么物种内个体之间的养育行为存在差异知之甚少。对养育子女的一致性个体差异的一个可能的解释是，个人投资于父母照顾的不同方面，如供应或防御。在这项实地研究中，我们测量了一致的养育行为的个体差异，并评估了养育和其他行为之间的相关性在三棘鱼（Gasterosteus aculeatus）。我们反复测量男性养育行为和男性行为的存在下，三种不同类型的生活入侵者：一个女性，一个同种男性，和一个捕食者，分别是为了挑起求爱，侵略性和antipredator行为。虽然男性可塑性调整他们的反应，不同类型的入侵者，我们发现一致的行为（行为类型）内和跨上下文的个体差异，即使在占身体大小和巢特征的变化。表现出更多养育行为的男性对所有类型的入侵者反应更快。这些结果表明，在自然界中，个别男性刺鱼表现出强大的父母的行为类型，和高父母的男性更注意他们的周围环境。未来的研究需要检查该领域父母行为个体差异的潜在原因。
Consistent individual differences in parenting are widespread; however, we know little about why there is variation in parenting behavior among individuals within species. One possible explanation for consistent individual differences in parenting is that individuals invest in different aspects of parental care, such as provisioning or defense. In this field study, we measured consistent individual differences in parenting behavior and evaluated correlations between parenting and other behaviors in three-spined stickleback (Gasterosteus aculeatus). We repeatedly measured male parenting behavior and male behavior in the presence of three different types of live intruders: a female, a conspecific male, and a predator, meant to provoke courtship, aggressive, and antipredator behavior, respectively. While males plastically adjusted their reactions to different types of intruders, we found consistent individual differences in behavior (behavioral types) both within and across contexts, even after accounting for variation in body size and nest characteristics. Males that performed more parenting behavior responded faster to all types of intruders. These results suggest that in nature, individual male sticklebacks exhibit robust parental behavioral types, and highly parental males are more attentive to their surroundings. Future studies are needed to examine the potential causes of individual variation in parental behavior in the field.
