How is dingo urine gathered? Carefully, study says

  澳洲野狗尿新用途

  SYDNEY (Reuters) - Australian researchers say they have discovered a new repellent(驱赶剂) that can help with everything from rehabilitating(复原) old mine(矿) sites to reducing the amount of roadkill. It's dingo(澳洲野狗) urine(尿).

  Researchers at Curtin University have been startled(震惊) by the effectiveness of urine from Australia's wild dogs in scaring off kangaroos which chew(咀嚼) through areas of new-growth vegetation(植物).

  The university's Michael Parsons said the discovery could have important applications(应用) in helping to re-establish plant life on old mine sites by repelling kangaroos, unique Australian marsupials(有袋动物) which number in the tens of millions.

  Researchers looked at the effectiveness of chemicals(化学制品) found in the urine of dingoes and non-native predators(食肉动物) like coyotes(山狗).

  "When we presented tame(驯服的) kangaroos with coyote urine, they became interested in the new smell, but when presented with the dingo urine they were startled and fled(逃跑)," Parsons said.

  He told Reuters on Tuesday that the effect of urine on wild kangaroos was even more dramatic.

  Parsons's team is looking at ways of delivering the repellent effectively at mine sites and how much would be needed, as well as whether it could be used to reduce the number of collisions between kangaroos and vehicles on outback roads.

  He said the university was also trying to isolate and synthesise(合成) the active chemicals in dingo urine so that it could be made in quantities large enough to be commercially viable(可行的).

  For now, the university is receiving supplies of the real thing from Australia's Dingo Conservation Society, but he said how it is gathered is a tightly held secret.

  "At one stage we fashioned a little urine catcher to walk dingoes and collect it from, but that tended to be risky," Parsons said.

  Note:

  澳大利亚学者发现袋鼠十分厌恶澳洲野狗尿的气味,只要闻到它就会立即逃走,但对于其他的狗的尿非但不害怕还会对新气味感到好奇。因此,科学家们准备量产“澳洲野狗尿”,用来驱散破坏植物、矿山和妨碍交通的淘气袋鼠们。
