In their Roadmap 2018 they include the LTER-Europe network, of which Umeå University is a member. "This gives us great hopes for the future, says Johan Wikner", director of Umeå Marine Sciences Centre. Mon, 17 Sep 2018 10:58:00 GMT 2018-09-17T10:58:00Z Greenhouse emissions from Siberian rivers peak as permafrost thaws Permafrost soils store large quantities of frozen carbon and play an important role in regulating Earth’s climate. In a study published in Nature Geoscience, researchers from Umeå University, Sweden, in collaboration with an international team, now show that river greenhouse gas emissions rise high in areas where Siberian permafrost is actively thawing.

This phenomenon, known as “browning,” was anticipated to cause widespread declines in fish populations. A new study by researchers from Umeå University finds that the number of fish populations impacted by browning is smaller than previously believed. Wed, 08 Aug 2018 08:00:00 GMT 2018-08-08T08:00:00Z Restoration project nominated for EU prize The restoration project ”Vindel River LIFE”, coordinated by Umeå University, is one of totally 28 EU LIFE-funded projects that has been nominated for the EU-prize ”The Life Award – Best of the Best Nature Projects”. ”It is a great honour for us to have been placed among the best projects in Europe”, says the project leader Johanna Gardeström. ”It is a nice support for our hard work during almost six years.” Mon, 11 Jun 2018 10:08:00 GMT 2018-06-11T10:08:00Z Nutrient limitation constrains arctic stream responses to climate warming Many current climate studies focus solely on increases in temperature, and in doing so, the ecosystem effects caused by climate change may be misinterpreted. In a new study, Umeå researchers are emphasising that shortage of nitrogen can limit how arctic streams respond to global warming. The results are published in the journal Global Change Biology. Thu, 05 Apr 2018 13:08:00 GMT 2018-04-05T13:08:00Z More teachers with pedagogical qualification Last week, 14 teachers were appointed qualified teachers and four were appointed excellent teachers in the Umeå University pedagogical qualification model. With this latest addition, the number of qualified and merited teachers has now reached 139, which places Umeå University second in Sweden. Wed, 28 Mar 2018 09:31:00 GMT 2018-03-28T09:31:00Z Arctic worming? 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. Fri, 16 Feb 2018 06:54:00 GMT 2018-02-16T06:54:00Z Traces of historical reindeer grazing can still be observed after 100 years With the holiday season around the corner, most people may first think of reindeer as Santa Claus' trusted helpers. 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. Mon, 11 Dec 2017 09:59:00 GMT 2017-12-11T09:59:00Z EcoChange digs deep into disrupted food web Climate change will make the marine food web less efficient, and toxic substances will increase in fish and other organisms. 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. Fri, 08 Dec 2017 07:42:00 GMT 2017-12-08T07:42:00Z Pupils and study supervisors from Vaasa learn about Umeå University's programmes 20 potential students and three study supervisors from Swedish speaking upper secondary Schools in Närpes, Vasa Gymnasium and Vasa Övningsskola are currently visiting Umeå University for two days. It is the fourth consecutive year that the study visit is organized. Thu, 23 Nov 2017 09:51:00 GMT 2017-11-23T09:51:00Z
