News from the Department of Ecology and Environmental Sciences at Umeå University, Sweden http://www.emg.umu.se/ViewPage.action?siteNodeId=2238&languageId=1&contentId=-1 RSS Feed from the Department of Ecology and Environmental Sciences at Umeå University, Sweden Arctic worming? http://www.emg.umu.se/ViewPage.action?siteNodeId=7094&languageId=1&contentId=290242 In North America, the spread of European earthworms is a known environmental issue as it has turned out that some of these species are capable of altering entire forest ecosystems. In Sweden, we have so far had a positive approach to earthworms and no policies have been put in place to limit the spread of these worms in Swedish national parks. A new study from Umeå University in North Sweden now shows that the Swedish approach may need revision.

But it turns out that reindeer are not only good at pulling Santa's sleigh; they can also teach us important lessons about the functioning of ecosystems. By studying small meadows in the Swedish mountains, formed by historical traditional reindeer herding practices, Dagmar Egelkraut revealed long-lasting ecological effects induced by reindeer grazing in her doctoral research.

This became clear during the first phase of EcoChange, and now it´s time to dig deeper into these questions. “A large part of our work concerns what the effects of the loss in food web efficiency leads to” says Agneta Andersson, professor in marine ecology at Umeå University and coordinator for EcoChange.

It is the fourth consecutive year that the study visit is organized.

This is a critical missing piece of the puzzle for understanding the role of lake carbon cycling at large spatial scales.

This according to researchers at the Department of Ecology and Environmental Science at Umeå University in a study published in the journal Methods in Ecology and Evolution.

The results of a study coordinated from Umeå University in Sweden are now published in Nature Communications.

This is shown by a new study from Umeå University.
