科普專欄–薯不揀單 - 三十秒科學–低溫加暴雨對企鵝的影響

氣候趨向極端化一直是備受關住的問題。有研究人員為了調查氣候轉變對企鵝的生態影響，特意從1983年起至2010年觀察阿根延某地域的企鵝狀況。789Please respect copyright.ＰＥＮＡＮＡIueFjPhO01

（圖2）該阿根延地域一直是較為乾旱的地區，下雨量並不多。789Please respect copyright.ＰＥＮＡＮＡSIr0hDAO61

然而，氣象模型預測，由20世紀起，該地域的暴雨出現率將會由每20年出現1次，轉變成由2046年起每10-15年1次，遞升2081年起每7-15年1次。789Please respect copyright.ＰＥＮＡＮＡlKj67tKsOj

（圖3）研究發現，如果暴雨伴隨低溫的話，界乎20-30日大的企鵝會極度容易面臨死亡。789Please respect copyright.ＰＥＮＡＮＡVAuEqulRlA

原因相信是企鵝因無法保持正常體溫致死；789Please respect copyright.ＰＥＮＡＮＡleNfUG7LmX

企鵝初期並未發生換羽過程，沒有防水的羽毛保護自己。而初生BB有父母保護，所以這並不是問題。789Please respect copyright.ＰＥＮＡＮＡ32H4d6QY6G

唯獨是處於換羽過程中的青年，牠們沒有父母及防水羽毛的蔭護，濕身加低溫便成為致命之傷。789Please respect copyright.ＰＥＮＡＮＡA9HAxe2oG8

而已換羽的企鵝有羽毛保護，所以低溫濕身不成威脅，因此亦造就了特別是20-30日歲數大企鵝的慘重死亡情況。789Please respect copyright.ＰＥＮＡＮＡeHS5AlveBm
