Abstract
Studies of eusocial insects have extensively investigated two components of task allocation: how individuals distribute themselves among different tasks in a colony and how the distribution of labor changes to meet fluctuating task demand. While discrete age- and morphologically-based task allocation systems explain much of the social order in these colonies, the basis for task allocation in non-eusocial organisms and within eusocial castes remains unknown. Building from recent advances in the study of among-individual variation in behavior (i.e., animal personalities), we explore a potential mechanism by which individuality in behaviors unrelated to tasks can guide the developmental trajectories that lead to task specialization. We refer to the task-based behavioral syndrome that results from the correlation between the antecedent behavioral tendencies and task participation as a task syndrome. In this review, we present a framework that integrates concepts from a long history of task allocation research in eusocial organisms with recent findings from animal personality research to elucidate how task syndromes and resulting task allocation might manifest in animal groups. By drawing upon an extensive and diverse literature to evaluate the hypothesized framework, this review identifies future areas for study at the intersection of social behavior and animal personality.

任务综合症:将社交动物群体中的个性和任务分配联系起来

摘要
对真社会性昆虫的研究广泛调查了任务分配的两个组成部分:个体如何在群体中的不同任务中分配自己,以及劳动力的分配如何变化以满足波动的任务需求。虽然基于年龄和形态的离散任务分配系统解释了这些殖民地的大部分社会秩序,但非真社会生物和真社会种姓中任务分配的基础仍然未知。基于对个体间行为差异(即动物个性)研究的最新进展,我们探索了一种潜在机制,通过该机制,与任务无关的行为中的个性可以指导导致任务专业化的发展轨迹。我们将基于先行行为倾向和任务参与之间的相关性导致的基于任务的行为综合征称为任务综合征。在这篇综述中,我们提出了一个框架,该框架将真社会有机体长期任务分配研究的概念与动物个性研究的最新发现相结合,以阐明任务综合征和由此产生的任务分配如何在动物群体中表现出来。通过利用广泛而多样的文献来评估假设的框架,本综述确定了社会行为和动物个性交叉点的未来研究领域。我们提出了一个框架,该框架将来自真社会有机体任务分配研究的悠久历史的概念与动物个性研究的最新发现相结合,以阐明任务综合症和由此产生的任务分配如何在动物群体中表现出来。通过利用广泛而多样的文献来评估假设的框架,本综述确定了社会行为和动物个性交叉点的未来研究领域。我们提出了一个框架,该框架将来自真社会生物长期任务分配研究的概念与动物个性研究的最新发现相结合,以阐明任务综合征和由此产生的任务分配如何在动物群体中表现出来。通过利用广泛而多样的文献来评估假设的框架,本综述确定了社会行为和动物个性交叉点的未来研究领域。
