【明報專訊】科學家發現,由於北極 海冰形成時間延後,一些饑餓的北極熊被迫以幼熊為食物,今年以來,至少已有7宗北極熊獵食幼熊的案例被發現。加拿大環境部退休生物學家斯特林(Ian Stirling)表示,這是他從事科學工作以來,首次見到這麼多北極熊獵食幼熊的案例。他指出,證據顯示,北極熊獵食幼熊,完全是為了食物,而非再交配。
海冰漸薄 不足支撐北極熊
斯特林解釋,哈德遜灣(Hudson Bay)的海冰,以往很早就形成,北極熊可以利用海冰接近海豹,獵食後積聚過冬所需的脂肪,但現在哈德遜灣的海冰形成比以往要晚數周,饑餓的北極熊等不及,只好先吃幼熊。
加拿大另一項最新研究亦稱,作為北極熊家園的北極海冰,以往在夏天通常仍能保存下來,但現在已變得愈來愈薄,部分甚至更是消失掉。研究員稱,一些沒有消融的海冰,其厚度根本不足以支撐北極熊站在其上。專家稱,北極海冰過去長期覆蓋近九成北極盤地,但現在覆蓋面僅及19%;過去通常厚達10米,但現在最多僅2米。
