If a doe in heat walks a few hours from the one small red zone into the grey zone, does she not get serviced? If she does get serviced and gives birth to two does, does the mother or father determine when they when they will go into estrous? Damn my head hurts.
I think this is why it remains so disjointed. Does have small home ranges, bucks roam. Sure, some deer will swim across deep and wide rivers, but I'd think most does never find a reason to do so. Hence the Tennessee, Tombigbee, and Chatahoochee rivers pretty well contain the state's does. Then on smaller levels all you ever have is some blending on the edges of doe populations, with the geographic cores of those initial restocks being very, very slow to grow if it all.
Not a biologist but I'd think that accounts for most of the weirdness. Their really is no explanation outside of that down here when on one side of the Chatahoochee they rut in November and on the other side in January.
