本周第四條,原文鏈接:http://www.sciencemag.org/content/338/6113/1400.1.full.pdf Mukojima, Japan 4 Albatrosses Colonize New Breeding Site 信天翁開拓新的繁殖地 After years of waiting, Japanese efforts to reintroduce short-tailed albatrosses to a historic and safer breeding site paid off. Last week, researchers reported that they had found the first egg known to result from the mating of an adult that had been translocated as a chick to this new site. Since 2008, researchers have been taking chicks from Torishima, where an established breeding colony is considered threatened by an active volcano, and hand-raising them on Mukojima, 350 kilometers to the south. 日本科學家一直努力重新讓短尾信天翁在一個重要而又更加安全的繁殖地安家,經(jīng)歷幾年的等待之后,他們的付出終于獲得了回報。上周,研究者報告稱他們發(fā)現(xiàn)一只雛鳥時就被搬遷的信天翁產(chǎn)下了這個新繁殖地的第一顆鳥蛋。2008年以來,因為受島上活火山的威脅,研究者不斷把雛鳥從之前的繁殖地鳥島(Torishima)搬運到350公里以南的Mukojima,并在那里人工撫育。 Short-tailed albatrosses, considered vulnerable by the International Union for Conservation of Nature, spend several years at sea before returning to their natal island to mate. “It’s a very important development” in reintroducing the birds to Mukojima, says conservation biologist Kiyoaki Ozaki at the Yamashina Institute for Ornithology in Abiko. The chick should hatch in January and fledge in May. Ozaki says they hope their techniques and experience can be applied to other sites and species. 短尾信天翁被國際自然保護聯(lián)盟認為是易受傷害的種群,它們會在海上度過數(shù)年之后返回出生地繁殖下一代。環(huán)保生物學家Kiyoaki Ozaki就職于Abiko的Yamashina鳥類研究所,他表示,就重新把信天翁引入Mukojima 來說“這是非常重要的進展”。雛鳥應該在一月份破殼,五月份羽翼豐滿。Ozaki說他們希望他們的技術和經(jīng)驗能夠推廣到其它繁殖地和鳥類。 *************************************************************** Science的原文和本翻譯僅用于網(wǎng)友交流學習之用,若您有其它用途,比如商業(yè)用途等,請聯(lián)系Science雜志社了解原文使用權等相關事宜。謝謝! |
