Leaving rats in Antarctica didn’t populate the continent with cold resistant rodents. Not all introduced species become invasive.

I was building on the previous comment as well as yours because I agree with your point. Just like how ice based species won’t take over warm areas, species adapted to warm environments wouldn’t take over the south pole if left there. They’d die before they could adapt or evolve.
