U.S. National Science Foundation-supported research shows that caribou will optimize their migration path based on their collective memories. Caribou are the most abundant large mammal species on land in the Arctic. They are not only an important part of the ecology but are also a primary source of food for hundreds of communities. The antlered deer migrate […]
Northern pike are moving through salt water to invade freshwater habitats in Southcentral Alaska, according to a new study. Researchers at the University of Alaska Fairbanks and the Alaska Department of Fish and Game made the discovery by collecting and analyzing tiny ear stones called otoliths from northern pike caught in the region. It’s the first […]
Analysis of a massive database of pink salmon DNA has revealed unexpected details about the abundant salmon species, including its ability to return to spawn at nearly the same spot within streams as their parents. 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 […]
