Shift in caribou movements may be tied to human activity

(University of Cincinnati) Human activities might have shifted the movement of caribou in and near the Arctic National Wildlife Refuge, according to scientists who tracked them using isotopic analysis from shed antlers. The study is timely given the auction this year of oil and gas leases in the Arctic National Wildlife Refuge. Indigenous Alaskans opposed the leases, arguing development could disrupt the migration of caribou they depend on for sustenance.

When it comes to eyewitness accounts of earthquake shaking, representation matters

As scientists increasingly rely on eyewitness accounts of earthquake shaking reported through online systems, they should consider whether those accounts are societally and spatially representative for an event, according to a new article.

Discovery of new praying mantis species from the time of the dinosaurs

A research team has identified a new species of praying mantis thanks to imprints of its fossilized wings. It lived in Labrador, in the Canadian Subarctic around 100 million years ago, during the time of the dinosaurs, in the Late Cretaceous period. The researchers believe that the fossils of the new genus and species, Labradormantis guilbaulti, helps to establish evolutionary relationships between previously known species and advances the scientific understanding of the evolution of the most ‘primitive’ modern praying mantises.
