Samuel May, a postdoctoral fellow at the University of Alaska Fairbanks College of Fisheries and Ocean Sciences, led a project that […]
A recent study— the largest of its kind— showed unpredictable changes in juvenile salmon migration timing in response to climate change. A new study published in the journal Nature Climate Change has found that salmon migration timing is changing in unpredictable ways in response to climate change. Dr. Eric Ward of NOAA Fisheries’ Northwest Fisheries Science Center was […]
Caribou have been using the same Arctic calving grounds for more than 3,000 years, according to a new study by the University of Cincinnati. Female caribou shed their antlers within days of giving birth, leaving behind a record of their annual travels across Alaska and Canada’s Yukon that persists on the cold tundra for hundreds […]
CORVALLIS, Ore. – Researchers have pinpointed two intervals when ice and ocean conditions would have been favorable to support early human migration from Asia to North America late in the last ice age, a new paper published today in the Proceedings of the National Academy of Sciences shows. The findings align with a growing body of evidence […]
