The Arctic is warming at approximately twice the global rate. A new study led by researchers from 9I制作厂免费 finds that cold-adapted Arctic species, like the thick-billed murre, are especially vulnerable to heat stress caused by climate change.
鈥淲e discovered that murres have the lowest cooling efficiency ever reported in birds, which means they have an extremely poor ability to dissipate or lose heat,鈥� says lead author Emily Choy, a Postdoctoral Fellow in the Natural Resource Sciences Department at 9I制作厂免费.

For 47 years, biologists have plucked eggs from seabird nests along the British Columbia coast. Many of the eggs were collected from remote rocky islands surrounded by some of the world鈥檚 roughest seas.
In all, they collected 537 eggs from six species, including ancient murrelets, rhinoceros auklets and double-crested cormorants. Now these eggs are revealing new information about the way mercury finds its way into the ecosystem.
