Social contexts and behavioural decisions in animals

在种群中，个体动物（包括人类）在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，许多工作仍然要阐明产生和维持这种变化的机制，以及后者对选择和进化过程的影响。 为了迎接这一挑战，目前提出的研究目标在短期内，以确定在何种程度上社会背景（社会因素）和社会获得的信息影响个人的行为决定，生活在社会群体。 更具体地说，我建议调查某些重要社会因素对以下方面的潜在影响：（i）雌性复制观察到的其他雌性的择偶倾向（即配偶选择复制行为），从而对性选择的强度，（ii）男性交配策略，以及（iii）个人之间特殊社会联系的形成和维持，以及这种联系对自然界中社交网络的影响。人口。

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 contexts (social factors) and socially-acquired information influence 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) male mating tactics, and (iii) the formation and maintenance of particular social associations among individuals and the implications of such associations for social networks in natural populations.
