The study of behavioral syndromes aims to understand among-individual correlations of behavior, yielding insights into the ecological factors and proximate constraints that shape behavior. In parallel, interest has been growing in behavioral plasticity, with results commonly showing that animals vary in their behavioral response to environmental change. These two phenomena are inextricably linked—behavioral syndromes describe cross-trait or cross-context correlations, while variation in behavioral plasticity describes variation in response to changing context. However, they are often discussed separately, with plasticity analyses typically considering a single trait (univariate) across environments, while behavioral trait correlations are studied as multiple traits (multivariate) under one environmental context. Here, we argue that such separation represents a missed opportunity to integrate these concepts. Through observations of multiple traits while manipulating environmental conditions, we can quantify how the environment shapes behavioral correlations, thus quantifying how phenotypes are differentially constrained or integrated under different environmental conditions. Two analytical options exist which enable us to evaluate the context dependence of behavioral syndromes—multivariate reaction norms and character state models. These models are largely two sides of the same coin, but through careful interpretation we can use either to shift our focus to test how the contextual environment shapes trait covariances.

上下文相关的特征协方差:可塑性如何塑造行为综合症

行为综​​合症的研究旨在了解行为之间的相互关系,深入了解影响行为的生态因素和邻近约束。同时,人们对行为可塑性的兴趣也在增长,其结果通常表明动物对环境变化的行为反应各不相同。这两种现象有着千丝万缕的联系-行为综合症描述了跨性格或跨语境的相关性,而行为可塑性的变化则描述了对变化的情境的响应。但是,通常将它们分开讨论,可塑性分析通常考虑跨环境的单个特征(单变量),而行为特征相关性则在一个环境下作为多个特征(多变量)进行研究。这里,我们认为,这种分离代表了整合这些概念的错失良机。通过在操纵环境条件时观察多个特征,我们可以量化环境如何塑造行为相关性,从而量化在不同环境条件下如何对表型进行差异约束或整合。存在两个分析选项,使我们能够评估行为综合症的情境依赖性—多元反应规范和角色状态模型。这些模型在很大程度上是同一枚硬币的两个方面,但是通过仔细的解释,我们可以使用任一模型来转移我们的注意力,以测试上下文环境如何塑造特征协方差。我们可以量化环境如何塑造行为相关性,从而量化在不同环境条件下表型如何受到差异约束或整合。存在两个分析选项,使我们能够评估行为综合症的情境依赖性—多元反应规范和角色状态模型。这些模型在很大程度上是同一枚硬币的两个方面,但是通过仔细的解释,我们可以使用任一模型来转移我们的注意力,以测试上下文环境如何塑造特征协方差。我们可以量化环境如何塑造行为相关性,从而量化在不同环境条件下表型如何受到差异约束或整合。存在两个分析选项,使我们能够评估行为综合症的情境依赖性—多元反应规范和角色状态模型。这些模型在很大程度上是同一枚硬币的两个方面,但是通过仔细的解释,我们可以使用任一模型来转移我们的注意力,以测试上下文环境如何塑造特征协方差。存在两个分析选项,使我们能够评估行为综合症的情境依赖性—多元反应规范和角色状态模型。这些模型在很大程度上是同一枚硬币的两个方面,但是通过仔细的解释,我们可以使用任一模型来转移我们的注意力,以测试上下文环境如何塑造特征协方差。存在两个分析选项,使我们能够评估行为综合症的情境依赖性-多元反应规范和角色状态模型。这些模型在很大程度上是同一枚硬币的两个方面,但是通过仔细的解释,我们可以使用任一模型来转移我们的注意力,以测试上下文环境如何塑造特征协方差。
