  国际自然保护联盟(IUCN)根据物种灭绝风险评估的标准,每年发布一次“红色名录”。但凡被归类为“易危”的动物物种意味着只有不超过一万只有繁殖能力的动物幸存,而且此类动物总数在每三代繁衍过程中以至少10%的比例减少。哪些物种出现在新的名录里,又有哪些物种幸免被收录其中?请听报道。

  Every year a United Nations’ conservationbody publishes a so called ‘red list’ of species at risk ofextinction. And as usual, the latest report makes grimreading. More than twenty thousand different types of animals, plants and insects are said to be threatened.

  Six kindsof ash tree in North America, a mainstay of forest there, are now listed as being in danger from an invasivebeetle. In Africa, antelopesjoined the ranks of creatures threatened by poaching and by people clearing forests.

  And in Madagascar, a hotspot for biodiversity, new studies of insects have found that nearly half of all species of grasshopper and millipedeare endangered.

  The beautiful snow leopard which lives in the mountains of Central Asia is judged to be in a slightly healthier state than it was. But that's disputed by some researchers who say not enough is known about the elusiveanimal to assume that it really is a step further away from extinction.
