Derek Arnold and male Canada lynx (IMAGE) University of Alaska Fairbanks Caption Derek Arnold, researcher at the University of Alaska Fairbanks Institute of Arctic Biology, carries a male lynx weighing around 24 pounds. It was captured in a log box trap near Stuver Cabin on the Tetlin National Wildlife Refuge in 2017. The lynx, in excellent condition during a population peak, was anesthetized and collared. After its release, the lynx dispersed eastward toward southern Yukon Territory. The log box trap used for its capture is visible in the background.
