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’ conservation body publishes a so called ‘red list’ of species at risk of extinction. And as usual, the latest report makes grim reading. More than twenty thousand different types of animals, plants and insects are said to be threatened.
Six kinds of ash tree in North America, a mainstay of forest there, are now listed as being in danger from an invasive beetle. In Africa, antelopes joined 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 millipede are 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 elusive animal to assume that it really is a step further away from extinction.
