Question

Seoul

 

A dangerous new bird flu in South Korea has spread nationwide despite efforts to make on the virus．Authorities have killed 2.8 million household chickens and ducks since the outbreak began，and the flu has also killed dozens of Baikal teal and other migratory birds．As yet，there are no reports of human infections．Scientists are puzzling over where the H5N8 flu，never before seen in a highly pathogenic（病原的）form，originated．

Portland，Oregon

 

A tiny chub （鲦鱼)has bounced back from near extinction(灭绝) ．The U.S. Fish and Wildlife Service (FWS)says populations of the Oregon chub are healthy enough to remove the 9-cm-long fish from its list of threatened and endangered wildlife．Last week’s announcement marks the first time an endangered fish has recovered enough to be delisted

After the 1940s, the chub populations dropped sharply from habitat damage by pollution and dams．When the fish was listed by FWS in 1993，only nine remained．Predation(捕食)by large-mouth bass and other non-native fishes was the largest threat to the remaining chub．

Since then, the Oregon Department of Fish and Wildlife and other groups started 20 new populations of the chub in predator-free ponds Changes to dam management have lowered the threat to remaining habitat．

Mexico City

 

The axolotl salamander’s only known home in the wild，the Xochimilco canals of Mexico City，has become increasingly polluted，but recent reports of the salamander’s extinction have been overstated．

Two weeks after announcing that months of searching the canals hadn’t turned up any axolotls，scientists in Mexico City have some good news：two of the unique salamanders were spotted on 4 February “There’s been an alarming reduction in population．”says Luis Zambrano, a biologist at the National University of Mexico，“but I can guarantee that is not yet extinct in the wild．”
