Collective behaviours, such as flocking in birds or decision making by bee colonies, are
some of the most intriguing behavioural phenomena in the animal kingdom. The study of …

The age of individuals has consequences not only for their fitness and behaviour but also for
the functioning of the groups they form. Because social behaviour often changes with age …

In long-lived organisms, experience can accumulate with age, such that older individuals
may act as repositories of ecological and social knowledge. Such knowledge is often …

Proximate mechanisms of 'social ageing', ie shifts in social activity and narrowing of social
networks, are understudied. It is proposed that energetic deficiencies (which are often seen …

Ageing affects almost all aspects of life and therefore is an important process across
societies, human and non-human animal alike. This article introduces new research …

Adverse experiences in early life are associated with aging-related disease risk and
mortality across many species. In humans, confounding factors, as well as the difficulty of …

The benefits of social living are well established, but sociality also comes with costs,
including infectious disease risk. This cost-benefit ratio of sociality is expected to change …

Age influences behaviour, survival, and reproduction; hence variation in population age
structure can affect population-level processes. The extent of spatial age structure may be …

Spatio-temporal variation in age structure influences social and demographic functioning,
yet we have limited understanding of the spatial scale at which its fluctuations are …

The relatedness between group members is a potential driver of variation in social structure.
Relatedness predicts biases in partner choice and formation of strong relationships among …
