Ice-Age Lesson: Large Mammals Need Room to Roam
![University of Alaska Fairbanks researcher Daniel Mann holds a steppe bison skull from the last ice age that he and fellow UAF researcher Pamela Groves found with the rest of its well-preserved skeleton. Although the Arctic’s frozen ground preserves bones exceptionally well, said Mann, it’s rare to find such a complete skeleton. The bison, which the researchers nicknamed “Bison Bob,” dated to 40,000 years ago and still had some fur on it.

A study of life and extinctions among woolly mammoths and other ice-age animals suggests that interconnected habitats can help Arctic mammal species survive environmental changes. The study appears online Nov. 2 in the Proceedings of the National Academy of Sciences. Short periods of warm climate in the midst of the last ice age triggered boom-and-bust cycles in the populations of large mammals in […]
