Discuss, could have evolutionary simulation, for perhaps the social interaction parameters, and simulate to ask what configurations evolve under different environmental pressures.
Concluding summary and direction of future work.

Methods

Environmental structure

We define three areas which are used to represent movement preferences and disease dynamics. Each of the three areas has a length of \(2L\) and is defined using the \(x\)-coordinate of position.  The breeding area spans \(-3L\le x\le L\), has high disease transfer and low recovery rates, and is the preferred area for healthy individuals.  The transit area spans \(-L<x<L\), and has spatially varying disease transfer and recovery rates.  The recovery area spans \(L\le x\le3L\), has low disease transfer and high recovery rates, and is the preferred area for infected individuals.  These three areas are showen in Fig \ref{891832}A.
