Two members of our lab co-authored a recently published paper in Nature entitled "Environmental drivers of increased ecosystem respiration in a warming tundra"
Inga Svala and Ingvild contributed to an international effort along with 74 other scientists, synthesizing ecosystem respiration in response to experimental warming across multiple tundra sites and analyzing the drivers of increase. The results showed that an increase of air temperature by 1.4°C and in soil temperature of 0.4°C during the growing season increased ecosystem respiration by 30%. The magnitude of the warming effects on respiration was driven by variation in warming-induced changes in local soil conditions, that is, changes in total nitrogen concentration and pH and by context-dependent spatial variation in these conditions, in particular total nitrogen concentration and the Carbon:Nitrogen ratio. Inga Svala contributed with data from Icelandic site and a few Svalbard sites while Ingvild provided data from Zackenberg, Northeast Greenland.

Björn Gíslason, the communication manager for HÍ/UI, has prepared an posted a press release in Icelandic and English with a focus on those sites run by Inga (Iceland, Svalbard) and posted on the UI website: https://english.hi.is/news/understanding_climate_warming_impacts_on_carbon_release_from_the_tundra

Congratulations Inga and Ingvild!
