The timing of the first entry of humans into North America across the Bering Strait has now been set back 10,000 years. This has been demonstrated beyond a shadow of a doubt by Ariane Burke, a professor in Université de Montréal’s Department of Anthropology, and her doctoral student Lauriane Bourgeon, with the contribution of […]
66 million years ago, the sudden extinction of the dinosaurs started the ascent of the mammals, ultimately resulting in humankind’s reign on Earth. Climate scientists now reconstructed how tiny droplets of sulfuric acid formed high up in the air after the well-known impact of a large asteroid and blocking the sunlight for several years, […]
Managing fisheries means more than managing fish. To keep fisheries sustainable, managers need to make sure the ecosystems that support fish production stay healthy. An important part of Alaska’s marine ecosystems is the corals that create habitat for fish and their prey. Coral gardens provide refuge for fish, but may be vulnerable to fishing […]
The annual migration of some beluga whales in Alaska is altered by sea ice changes in the Arctic, while other belugas do not appear to be affected. A new study led by the University of Washington finds that as Arctic sea ice takes longer to freeze up each fall due to climate change, one […]
