New study emphasizes the relative scarcity of lake water

2017-04-12
What is the volume of water in lakes on Earth? Using a mathematical analysis, researcher David Seekell, at Umeå University, and his American collaborators now suggest that the mean depth of lakes is 30 per cent lower than previously estimated. Shallower lakes implies less fresh water and has consequ...

Renens betydelse i ett föränderligt klimat

The importance of the reindeer in an ever changing climate - Researchers at the Department of Ecology and Environmental Science present their research during Sami Week.

Winners and losers: climate change will shift vegetation

2017-02-16
Projected global warming will likely decrease the extent of temperate drylands by a third over the remainder of the 21st century coupled with an increase in dry deep soil conditions during agricultural growing season. These results have been presented in Nature Communications by an international col...

Northern lakes respond differently to nitrogen deposition

2017-02-06
Nitrogen deposition caused by human activities can lead to an increased phytoplankton production in boreal lakes. The response of boreal lakes to nitrogen deposition will strongly depend on each lake’s content of organic carbon, which are predicted to increase with future warmer and wetter climate. ...

BBC reports on climate research in Umeå

2017-01-31
The BBC has interviewed researcher Erik Björn owing to his internationally recognized new study that shows that climate change could lead to up to seven times more toxic mercury in fish.

Temperature change affects temperate mountain ecosystems globally

2017-01-25
The warmer climate that is expected over the next 80 years could lead to major disruptions in ecosystems of high mountain landscapes, for example by altered balance between nitrogen and phosphorus in the soil.

US ambassador visits CIRC and the Swedish Polar Research Secretariat in Abisko

2017-01-13
Swedish and United States partnerships in science and the polar regions have a long history. This week the United States Ambassador Azita Raji and her team Michael J. Layne and Kristy Plan visited the Abisko Scientific Research Station to experience the Arctic in winter in Sweden first-hand.

Climate is no ubiquitous explanation of fluctuations in reindeer numbers

2016-12-29
Exploitation of natural resources, such as forestry or gas and oil extraction, and management practices may have faster and greater impacts on reindeer populations than does climate change, a study finds. However, climate change should not be forgotten or underestimated, since reindeer are adapted t...

Could Rudolph and friends help slow down warming climate?

2016-12-22
Reindeer may be best known for pulling Santa's sleigh, but a new study led from Umeå University suggests they may have a part to play in slowing down climate change too. The results are published today in the journal Environmental Research Letters.

Ice project funded by Formas

2016-12-16
EcoChange researcher Jenny Ask has received funding from Formas for a project about ice-cover regimes in northern aquatic ecosystems. The project will focus on how future changes in ice-cover will impact aquatic carbon metabolism, algal biomass build-up and water-atmosphere gas exchange.
