Last year, the three children attacked by wild dogs on the popular australian island resort of Fraser Island. And every year costs dingoerne the australian agricultural sector is almost 300 million. Dingoerne sets like the teeth in people's livestock, and in very extreme cases small children.

They are unpopular, dingoerne, and has been for a long time. Since the 1940's has the australians put the dead, poisoned animals out for them to reduce the stock. A strategy, that now turns out to be a mistake. New research indicates that there is perhaps even greater reason to fear dingoerne, as the only major extant predators back in Australia has gained a reputation similar to the wolf in Europe. It writes DR. dk.

Back in the'80s disappeared for a little girl from a campsite. The parents were convicted of the killing - the police did not believe it was a dingo who had taken his daughter. Six years after it was found the girl's clothes in a dingohule, and the parents were eventually acquitted. Picture: Colourbox

Australian scientists have measured the skulls of 600 dingoes, and in the areas where the poisoning of wild dogs have taken place, is dingoerne been between six and nine percent larger and an average of a kilo heavier.
There is not yet any conclusive evidence, what this størrelsesforøgning due. Scientists are working provisionally with two theories. The first point that many dingoes die of the poison, and that therefore there is more food for the survivors.
The other theory is that the poisoned baits have killed several of the smaller dingoes rather than the larger, because the larger body mass requires more of the poison. Therefore survives the biggest dingoes, and they will grow over time, writes Dr. dk.
According to Bengt Holst, scientific director at Copenhagen Zoo, it seems the last theory is likely.
- When a special genetic pressure on species, will adapt itself. So if being bigger is an advantage, because the poison does not kill you, it is natural, that the stock grows larger over time, he says to DR. dk, and also mention that there are countless examples of animal species because of humans have had to adapt to in a hurry.
