Rappelling down a 650-foot cliff to catch seabirds on a remote island just below the Arctic Circle was scary enough.
鈥淭he first time you look over and you rappel over, it鈥檚 certainly not for the faint of heart,鈥� said Kyle Elliott, a research chair in Arctic ecology at 香蕉视频 in Canada.
But for Elliott and fellow researcher Emile Brisson Curadeau, it was the hungry polar bears (Ursus maritimus) 鈥� usually one a day walking near their cabin 鈥� that raised real concerns, and devoured their research subjects.
