AMAP report says Arctic marine environment vulnerable to acidification
15.05.2013
A report released by the Arctic Council's Arctic Monitoring and Assessment Programme (AMAP) has found that the Arctic Ocean is particularly susceptible to ocean acidification, which could lead to significant changes in Arctic marine ecosystems. The report concluded that the acidity of the surface of the world's oceans increased by…

Mercury responsible for Arctic fox decline in Russian North Pacific Island
08.05.2013
Scientists were baffled by the sudden and significant decline in Arctic fox populations on Russia's Mednyi Island in the North Pacific, until a study by German and Russian researchers confirmed that it was not an infection or pathogen that has been causing their decline, but rather high levels of mercury…

Surprising co-dependency between pikas and wooly bear caterpillars in the Yukon
25.04.2013
Researchers from the University of Alberta have discovered a surprising symbiotic relationship between pikas (small, furry mammals) and Arctic wooly bear caterpillars in a study examining competition for scarce food resources in the Yukon: pikas preferred gathering food from areas that had first been grazed upon by the caterpillars.

Scientists able to link terrestrial paleoclimate to atmospheric CO2 levels using new method
23.04.2013
Researchers have used a new geochemical method to measure how temperatures on land changed when the planet's climate transited from a warm greenhouse climate to a cooler icehouse climate between 34 and 33.5 million years ago.xt century, which could have significant impacts on the planet and its ecosystems.

Development of ice cover in Antarctica led to appearance of near-modern ecosystems in region
22.04.2013
An international team of researchers including scientists from Utrecht University and Imperial College London looked at how the development of a permanent ice sheet and seasonal sea ice cover in Antarctica led to the evolution of ecosystems not too different from the ones that exist there today. The changing conditions…
