研究發現瑞士國家公園及義大利大帕拉迪索國家公園的羱羊，因氣候暖化而開始轉為夜間活動。日行性的羱羊通常白天在山脈上吃草。夜間覓食不僅會降低了牠們覓食的效率，還會增加了遇到如狼等捕獵者的機會。
Researchers discovered the alpine ibex in the Swiss National Park and the Italy’s Gran Paradiso National Park, are shifting to more nocturnal as weather becomes hotter. Alpine ibex usually graze on the rocky mountains during the day. Foraging at night not only lower their efficiency for food searching, but also increase their chances to encounter their predators like wolves.
