The hypothesis of the selfish herd has been highly influential to our understanding of animal
aggregation. Various movement strategies have been proposed by which individuals might …

There is a strong body of evidence that patterns of collective behaviour in grouping animals
are governed by interactions between small numbers of individuals within the group. These …

Single species aggregations are a commonly observed phenomenon. One potential
explanation for these aggregations is provided by the selfish herd hypothesis, which states …

The selfish herd hypothesis explains how social prey can assemble cohesive groups for
maximising individual fitness. However, previous models often abstracted away the physical …

Under the threat of predation, animals often group tightly together, with all group members
benefiting from a reduction in predation risk through various mechanisms, including the …

The selfish herd hypothesis predicts that aggregations form because individuals move
toward one another to minimize their own predation risk. The “dilemma of the selfish herd” is …

The selfish herd hypothesis provides an explanation for group aggregation via the selfish
avoidance of predators. Conceptually, and as was first proposed, this movement should aim …

Animal grouping behaviors have been widely studied due to their implications for
understanding social intelligence, collective cognition, and potential applications in …

Over two decades ago, WD Hamilton argued that animal grouping behavior could evolve if
individuals selfishly avoided predation by reducing their domains of danger (Voronoi …

From zebra to starlings, herring and even tadpoles, many creatures move in an organized
group. The emergent behaviour arises from simple underlying movement rules, but the …
