A physics perspective on collective animal behavior

NT Ouellette - Physical Biology, 2022 - iopscience.iop.org
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 …

Stochastic modelling of bird flocks: accounting for the cohesiveness of collective motion

AM Reynolds, GE McIvor… - Journal of the …, 2022 - royalsocietypublishing.org
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 …

Swarming: hydrodynamic alignment with pressure

E Tadmor - Bulletin of the American Mathematical Society, 2023 - ams.org
We study the swarming behavior of hydrodynamic alignment. Alignment reflects steering
toward a weighted average heading. We consider the class of so-called $ p $-alignment …

Swarm modeling with dynamic mode decomposition

E Hansen, SL Brunton, Z Song - IEEE Access, 2022 - ieeexplore.ieee.org
Modelling biological or engineering swarms is challenging due to the inherently high
dimension of the system, despite the often low-dimensional emergent dynamics. Most …

Understanding the thermodynamic properties of insect swarms

AM Reynolds - Scientific Reports, 2021 - nature.com
Abstract Sinhuber et al.(Sci Rep 11: 3773, 2021) formulated an equation of state for
laboratory swarms of the non-biting midge Chironomus riparius that holds true when the …

Spatial correlations in laboratory insect swarms

AM Reynolds - Journal of the Royal Society Interface, 2024 - royalsocietypublishing.org
In contrast with flocks of birds, schools of fish and herds of animals, swarms of the non-biting
midge Chironomus riparius do not possess global order and under quiescent conditions …

On the ideal gas law for crowds with high pressure

Z Li, L Fang - Physica A: Statistical Mechanics and its Applications, 2024 - Elsevier
Active particle systems, such as human crowds, are out of equilibrium posing a significant
challenge in identifying a suitable equation of state. However, several previous observations …

Active Particle Models for Animal Behavior based on Effective Nonreciprocal Forces and Potentials

A Haluts, D Gorbonos, NS Gov - arXiv preprint arXiv:2401.14850, 2024 - arxiv.org
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 …

Why insect swarms seem unduly complicated

AM Reynolds - The European Physical Journal Plus, 2024 - Springer
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 …

Inferring the size of a collective of self-propelled Vicsek particles from the random motion of a single unit

P De Lellis, M Porfiri - Communications Physics, 2022 - nature.com
Inferring the size of a collective from the motion of a few accessible units is a fundamental
problem in network science and interdisciplinary physics. Here, we recognize stochasticity …
