Summary
Swarming pattern formation of self-propelled entities is a prominent example of collective behavior in biology. Here we focus on bacterial swarming and show that the rod shape of self-propelled individuals is able to drive swarm formation without any kind of signaling.
The underlying mechanism we propose is purely mechanical and is evidenced through two different mathematical approaches: an on-lattice and an off-lattice individual-based model. The intensities of swarm formation we obtain in both approaches uncover that the length-width aspect ratio controls swarm formation. Moreover we show that there is an optimal aspect ratio that favors swarming.
