Many sensory systems in cells and organisms share a recurring property called fold-change
detection (FCD). FCD describes a system whose dynamics–including amplitude and …

The dynamic patterns and coordinated motion displayed by groups of social animals are a
beautiful example of self-organization in natural far-from-equilibrium systems. Recent …

Local social interactions among individuals in animal groups generate collective behavior,
allowing groups to adjust to changing conditions. Historically, scientists from different …

Collective behaviour can be difficult to discern because it is not limited to animal
aggregations such as flocks of birds and schools of fish wherein individuals spontaneously …

We study the systems of Euler equations that arise from agent-based dynamics driven by
velocity alignment. It is known that smooth solutions to such systems must flock, namely the …

Collective motion of large-scale natural swarms, such as moving animal groups or
expanding bacterial colonies, has been described as self-organized phenomena. Thus, it is …

Modelling animal behavior using active-particle models is a major current challenge. The
unique properties of animals mean that such models require the use of new types of …

Mating swarms of flying male insects are a form of collective behaviour, albeit one different
from flocks and schools as they do not display ordered collective movements. In recent …

In contrast to bird flocks, fish schools and animal herds, midge swarms maintain cohesion
but do not possess global order. High-speed imaging techniques are now revealing that …

Okubo (Okubo 1986 Adv. Biophys. 22, 1–94.(doi: 10.1016/0065-227X (86) 90003-1)) was
the first to propose that insect swarms are analogous to self-gravitating systems. In the …
