Within populations, individual animals (including humans) differ to varying degrees in their behaviour and reproductive success. Despite recent advances, much work remains to elucidate the mechanisms generating and maintaining such variation, and the consequences of the latter for the processes of selection and evolution. Towards meeting this challenge, the current proposed research aims in the short term to ascertain the extent to which social context (social factors) influences the behavioural decisions of individuals that live in social groups. More specifically, I propose to investigate the potential influences of certain important social factors on: (i) the tendency of females to copy the observed mate choice of other females (i.e. mate-choice copying behaviour) and thereby on the intensity of sexual selection, (ii) the formation and maintenance of particular social associations among individuals and the implications of such associations for social networks in natural populations and for the intensity of sexual selection, and (iii) risk-taking behaviour (i.e. "boldness"), as measured by tendency to explore novel environments and approach predators, and the relationships between boldness and correlates of individual fitness (e.g. growth rate).

在种群内部，个体动物(包括人类)在其行为和繁殖成功方面存在不同程度的差异。尽管最近取得了进展，但仍有许多工作要阐明这种变异的产生和维持机制，以及后者对选择和进化过程的影响。为了应对这一挑战，目前拟议的研究旨在短期内确定社会环境(社会因素)对生活在社会群体中的个人的行为决定的影响程度。更具体地说，我建议调查某些重要的社会因素对以下方面的潜在影响：(I)雌性模仿其他雌性的配偶选择的倾向(即配偶选择复制行为)，从而对性选择的强度产生影响；(Ii)个体之间特定社会联系的形成和维持，以及这种联系对自然种群中的社会网络和性选择强度的影响；以及(Iii)冒险行为(即“大胆”)，以探索新环境和接近捕食者的倾向来衡量，以及胆量与个体适合度的相关性(如生长速度)之间的关系。
