Correction to Eqs. (13)

We would like to report two typographical errors in Eqs. (13). In the equation for patch A, one of the (\lambda) terms in the quadratic part of the replicator equation should carry superscript indices ((2,1)). In the equation for patch B, the (\lambda) term in the linear part of the replicator equation should carry superscript indices ((1,2)).

These corrections are purely typographical and do not affect the results or conclusions of the paper.
