Paleontologists have retrieved ancient enamel protein sequences from a fossilized tooth of Epiaceratherium sp., a rhinocerotid that lived in Canada’s...
Polar ecosystems are structured and enriched by birds, which nest there seasonally and serve as keystone ecosystem members. Despite the ecological importance...
Researchers have examined three ice core records to identify lead pollution levels in the Arctic between 500 BCE through 600 CE. Lead isotopes allowed...
Bergmann’s rule is a scientific principle stating that animals in high-latitude, cooler climates tend to be larger than close relatives living in warmer...
Frostquakes are seismic events with frequencies of about 10-20 Hz and waveforms like those of tectonic events. They potentially can damage infrastructures...
A new genus and species of eutherian mammal has been described from a handful of tiny teeth found in the Prince Creek Formation in northern Alaska, the...
In new research, scientists analyzed 23 ancient genomes of woolly mammoths (Mammuthus primigenius), including one of the oldest known specimens at 700,000...
With ongoing carbon dioxide emissions from the burning of fossil fuels, the atmosphere of Earth heats up, which has dramatic consequences for the ice sheets....
Paleontologists from Uppsala University and the University of Oslo have found the 250-million-year-old fossilized ichthyosaur remains in the Vikinghøgda...
Paleontologists have described two new species of the early primatomorphan genus Ignacius from Ellesmere Island, Nunavut, Canada.
Life reconstruction of...
Researchers have analyzed microscopic fragments of 2-million-year-old environmental DNA from of the Kap København Formation in Greenland. The DNA record...
Qikiqtania wakei closely resembles Tiktaalik roseae — the important transitional animal considered a missing link between fish and the earliest limbed...
New research published in the American Museum Novitates is the first to document biofluorescence in Arctic fishes.

In a large-scale environmental DNA metagenomic study of ancient plant and mammal communities, an international team of researchers have analyzed 535 permafrost...
Scientists have examined isotopes collected from the tusk of a woolly mammoth (Mammuthus primigenius) that lived in Alaska approximately 17,100 years ago,...
A team of paleontologists from the University of Alaska Fairbanks and Florida State University has uncovered the first convincing evidence that several...
Microscopic multicellular animals called bdelloid rotifers are known for their ability to survive extremely low temperatures. They had been reported to...
Millions of migratory birds occupy seasonally favorable breeding grounds in the Arctic, but scientists know little about the formation, maintenance and...
