The average disease outbreak numbers in the last 25 generations (total simulated generations are 50) under the influences of growth ratio and migration rate for Robust type at patch #30, where robust type provides the baseline growth rate (in the absence of infection: i.e., rR). The color trend with numbers represent the trend of outbreak numbers: from blue to white to red, outbreak numbers increase. All the other parameters are: rR = 0.15, rWd = rRd = 0.01, rWr = rRr = 0.2, αW = αR = 0.05, μW = μR = 0.0005, γW = γR = 0.05, βRR = βWR = 0.000005 and βRW = βWW = 0.0001. In focal patch #1, the initial susceptibles of both types are 200, infecteds are 5, and recovereds are 0. Other patches show similar patterns.
