项目摘要

The study of between-individual variation in behavioural phenotypes, which previously has been perceived mainly as unexplained and insignificant variation, has gained significant attention during recent years and induced a major paradigm shift in behavioural ecology. Numerous recent studies have convincingly demonstrated that individuals show consistent behavioural phenotypes (i.e. personality) both in time and across contexts. Nevertheless, although many descriptive studies have revealed such individual differences in personality, experiments and models elucidating the causes for the evolution and maintenance of these differences are still rare. In this project, we will use theoretical approaches to shed new light on this unsolved problem. One sub-project will consist of a series of models focussing on general principles. The ambition is to incorporate sexual selection and the pace-of-life syndrome into theoretical models of behavioural types. This will increase the understanding how the potential interplay between sexual selection, life history, and metabolism can affect the emergence of behavioural types. Furthermore, with more specific models, inspired by the data gained in the empirical projects of our research group, we will explore the effects of i) seasonal differences, ii) varying intensity in maternal care, iii) food quality variation, and iv) state relative to litter-mates on the evolution and maintenance of behavioural phenotypes. This explicit modelling approach will be performed in close collaboration with the empirical groups, having the positive implication that the necessary realistic conditions will be implemented appropriately and that the involved empiricists will learn how to use modeling as an important scientific method.

行为表型个体间变异的研究，以前被认为主要是无法解释的和微不足道的变化，近年来获得了极大的关注，并引起了行为生态学的重大范式转变。最近的许多研究令人信服地表明，个体在时间和环境中表现出一致的行为表型（即个性）。然而，尽管许多描述性研究揭示了这种个性差异，但阐明这些差异的演变和维持原因的实验和模型仍然很少。在这个项目中，我们将使用理论方法来阐明这个未解决的问题。一个分项目将包括一系列侧重于一般原则的模型。其目标是将性选择和生活节奏综合征纳入行为类型的理论模型。这将增加对性选择、生活史和新陈代谢之间的潜在相互作用如何影响行为类型的出现的理解。此外，通过更具体的模型，受我们研究小组的经验项目中获得的数据的启发，我们将探索i）季节差异，ii）不同强度的孕产妇护理，iii）食物质量变化，iv）相对于同窝仔的状态对行为表型的演变和维持的影响。这种明确的建模方法将与经验团体密切合作进行，具有积极的意义，即必要的现实条件将得到适当的实施，参与的数学家将学习如何使用建模作为一种重要的科学方法。
