Across the animal kingdom, we see remarkable variation in brain size. This variation has
even increased over evolutionary time. Traditionally, studies aiming to explain brain size …

The scientific study of networks-computer, social, and biological-has received an enormous
amount of interest in recent years. However, the network approach has been applied to the …

Avoiding predation is generally seen as the most common explanation for why animals
aggregate. However, it remains questionable whether the existing theory provides a …

The schooling behaviour of fish is of great biological importance, playing a crucial role in the
foraging and predator avoidance of numerous species. The extent to which physiological …

Detailed quantifications of how predators and their grouping prey interact in three
dimensions (3D) remain rare. Here we record the structure and dynamics of fish shoals …

Many group-living animals show social preferences for relatives, familiar conspecifics or
individuals of similar attributes such as size, personality or sex. How such preferences could …

Predation is one of the main evolutionary drivers of social grouping. While it is well
appreciated that predation risk is likely not shared equally among individuals within groups …

Researchers have long noted that individuals occupy consistent spatial positions within
animal groups. However, an individual's position depends not only on its own behaviour, but …

The role of behavioural interactions in the development of fin damage amongst Atlantic
salmon (Salmo salar) undergoing feed-restriction was investigated using social network …

Broiler chickens are reported to be close to walls at higher densities. The reason for this is
not clear, since evolutionary theories would suggest that birds should attempt to be in the …
