Spatial dynamics of synchronized ants: A mobile oscillator model analysis
Synchronized short-term activity cycles are a prominent feature in the nests of certain ant species, but their functional significance remains controversial. This study investigates whether synchronization enhances spatial accessibility within ant nests, a factor critical for efficient task performance and colony fitness. We use the mobile oscillator model, a computational framework that simulates ant movement and synchronous activity, to examine the effect of synchronization on the spatial distribution of inactive ants, which act as obstacles to the movement of active ants. Our analysis reveals no significant effect of synchronization on the size of inactive ant clusters or on direct measures of spatial accessibility, such as the number of steps and net displacement during ant activity periods. These findings suggest that within the mobile oscillator model, synchronization does not directly enhance spatial accessibility, highlighting the need for more complex models to elucidate the intricate relationship between synchronization and spatial dynamics in ant colonies.

Physica A: Statistical Mechanics and its Applications
Recognized by the European Physical Society
Physica A publishes research in the field of statistical mechanics and its applications.
Statistical mechanics sets out to explain the behaviour of macroscopic systems by studying the statistical properties of their microscopic constituents.
Applications of the techniques of statistical mechanics are widespread, and include: applications to physical systems such as solids, liquids and gases; applications to chemical and biological systems (colloids, interfaces, complex fluids, polymers and biopolymers, cell physics); and other interdisciplinary applications to for instance biological, economical and sociological systems.
