Interesting article on science/data versus "common sense" in deer mgmt.

[QUOTE="BSK, post: 5584061, member: 17"] scn beat me to it. I was going to post a link to this article because of the section on restocked genetics. I don't know how many times I've heard from hunters or read on this site how deer in a specific part of the Southeast are different than other deer in the area because the location was restocked with "northern" deer. Yet those northern genetics got swamped right out of the population just a few decades after restocking, as native Southeast Whitetails spread outwards from remnant pockets. Our Southeast deer carry virtually no [B]expressed[/B] northern traits. Northern deer are VERY poorly adapted to southern climates and diseases, hence Nature selects [B]heavily against them.[/B] I remember a research project where very high-performing deer from Michigan were transplanted down to a research facility in Louisiana (I believe LSU). Their first year living in a southern climate, the Michigan bucks declined dramatically in antler growth, actually [B]underperforming[/B] local bucks. And within 2-3 years, all of the transplanted northern deer were dead. They had no natural immunity to local southern diseases and could not survive the southern climate. Now this doesn't mean that local populations can't be genetically linked to original restocking efforts. But these DNA links will be in sections of DNA that do not code for expressed traits. In essence, they will be remnant DNA that "doesn't do anything." Just like many people of European or Asian descent still carry DNA markers showing their link back to Neanderthals.
