描述父母照顾的个体差异对于理解选择如何塑造和维持照顾模式至关重要，但我们对父母个体对环境的反应如何变化知之甚少。反应规范是描述表型如何跨环境梯度变化的函数，为研究行为反应的个体差异提供了一个优雅的框架。我们使用反应范数方法来研究如何研究可塑性（描述个体随时间变化的变化）和个性（描述个体之间可重复的变化）共同解释海葵鱼父母行为的个体变化。更具体地说，我们测试资源可用性如何影响个体父母对环境的反应，并讨论对我们理解父母照顾中的可塑性和个性的影响。繁殖对的A. percula 被喂食高或低的食物配给，并监测它们的亲本行为。在两种资源环境中，个体的父母行为表现出可塑性。此外，随着时间的推移，个体的行为是可重复的，正如截距的个体间显着差异所证明的那样。最后，个体反应规范的斜率和高度有所不同，揭示了在群体水平上未捕获的变异水平，并提供了对产生个体变异的潜在机制的洞察。 (C) 2017 年动物行为研究协会。由爱思唯尔有限公司出版。保留所有权利。
Characterizing individual variation in parental care is critical to understanding how selection shapes and maintains patterns of care, yet little is known about how individual parents vary in their responses to the environment. Reaction norms, functions that describe how phenotypes change across an environmental gradient, provide an elegant framework for studying individual variation in behavioural responses. We use a reaction norm approach to investigate how studying plasticity, which describes variation within an individual through time, and personality, which describes repeatable variation among individuals, together explain individual variation in the parental behaviour of the anemonefish Amphiprion percula. More specifically, we test how resource availability influences individual parental responses to the environment and discuss the consequences for our understanding of plasticity and personality in parental care. Breeding pairs of A. percula were fed either a high or a low food ration and their parental behaviours were monitored. Individuals exhibited plasticity in parental behaviour across the two resource environments. Furthermore, individuals were repeatable in their behaviour through time, as evidenced by significant among-individual variation in intercept. Finally, the slope and elevation of individual reaction norms varied, revealing a level of variation not captured at the population level and providing insight into the potential mechanisms generating individual variation.
