Habitat loss exacerbates pathogen spread: An Agent-based model of avian influenza infection in migratory waterfowl
Fig 1
The visited migration networks generated by the simulated geese movement according to the agent-based model.
A) the complete network, and B-F) the network scenarios of 10%, 20%, 30%, 40% and 50% site removal. Dots are sites visited by geese, colors represent the maximum R0 that occurred at sites during the simulation, and numbers are site IDs. Yellow and blue shadows depict breeding and wintering regions. The base layer maps were generated in R environment using the “maps” package (Original S code by Richard A. Becker, Allan R. Wilks. R version by Ray Brownrigg.
