“…Some models use a generational time-step, others use a daily time-step, e.g., Crowder and Onstad [ 17 ], Crowder et al [ 28 ]. Some models are spatially explicit, that is there is a specific ordering and structure to patches (fields) so some patches are closer while others are more distant (concepts of distance, dispersal kernels and spread become important) [ 14 , 16 , 19 , 29 , 30 , 32 , 33 , 34 , 35 , 36 ]. Other models are spatially implicit and model populations with no spatial structure and movement is represented as an exchange of individuals between these populations without regards to distance [ 37 , 38 , 39 , 40 , 41 , 42 ].…”
