Computational exploration of treadmilling and protrusion growth observed in fire ant rafts

Fig 5

Dynamic Effects of Activity Level.

Snapshots of modelled rafts at different simulation times (t) and activity levels () are depicted to illustrate the effect of on raft development. The raft on the far left depicts the initial conditions which were the same for each simulation throughout this work (a circular raft with ϕ = 1). On the right each row depicts a single raft as it evolves in time (moving from left to right along the horizontal axis). For all simulations shown, η = 0.2 and R = 0.9 ℓ. Structural agents are depicted in cyan, while dispersed free agents are depicted in red. The scale bar in the top right is universal to all snapshots and represents 14 ℓ.
