Time evolution of two 2D systems, exhibiting the Ebola (upper row) and Diaspora (lower row) effects.
Both system have γ = 10−1 but different value of β. A, B and C agents are colored in red, green and blue respectively. Soon after their arrival to the system, the C agents quickly spread throughout the system (times 20,100). For higher β (upper row), with smaller B islands, the C's cannot reach certain parts of the system which are left unharmed; soon afterwards the C's go extinct (time 1000). The remaining island of B's (time 2000) slowly repopulate the whole system (time 10000). For lower β (lower row), the islands are bigger and thus the C's reach all of them and only a handful of B's survive on the fringe (time 300). These however have a higher chance of reaching an A agent by diffusion due to their longer lifespan, (time 1000) and once they do, they repopulate the system more rapidly due to the larger island size (time 3000).
