A new University of Alaska Fairbanks–led study has found that razor clams accelerate their shell development when exposed to more acidic ocean conditions, but that those young shells are built with more fragile substances. How shellfish react to changing marine conditions is a growing concern as climate change gradually shifts ocean chemistry. The threat of […]
Researchers have linked the travels of a 14,000-year-old woolly mammoth with the oldest known human settlements in Alaska, providing clues about the relationship between the iconic species and some of the earliest people to travel across the Bering Land Bridge. Scientists made those connections by using isotope analysis to study the life of a female […]
[content id=”79272″] 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 […]
Researchers have confirmed that salmon are spawning in an Arctic Ocean watershed, suggesting that at least some salmon species could be expanding to new territory as climate change reshapes their habitat. The University of Alaska Fairbanks-led project found about 100 chum salmon in the Anaktuvuk and Itkillik rivers on Alaska’s North Slope. Both rivers flow […]
