This is a good sign, simple and effective - although they could explain a little more the differences make them better adapted to different environments. Did they actually have their northern and southern koalas labelled as such for direct comparison?

Has anyone done extensive population genetics studies on the northern and southern koala populations to determine if there is any reproductive isolation between them?

there have been a number of genetic studies done on koala. Previously three subspecies were recognised, which oddly enough had ranges determined exactly by the state borders of Queensland, NSW and Victoria. Koala distribution is not continuous over their range because of their habitat requirements, and more-recently human disruption has fragmented the population units, but the genetics show that there are probably not enough differences overall to consider koala anything other than monotypic - however individual populations can be distinguished because of limited gene flow between them.

This sign was in front of an enclosure that contained one southern and a couple of northern koalas. There was a second southern koala elsewhere in the zoo, however there was no sign pointing that out.
