Mathematical and Theoretical Ecology in Umeå

2017-05-11
Theoretical and mathematical ecology is an interdisciplinary field, where scientists cooperate across borders to further our understanding of ecology an evolution by building conceptual and mathematical models. In this workshop, researchers from the Department of Mathematics and Mathematical Statist...

Chemistry world: Fish on valium

2017-05-08
What are the consequences of unintentionally medicating wildlife against anxiety and depression? Imagine what happens when, as has been extensively shown, that Prozac type of psychiatric medicine makes it into the wild. For Jonatan Klaminder, an ecologist at Umeå University in Sweden, it’s straightf...

Pathogenic bacteria train their defence in lakes and oceans

2017-05-04
Peter Mathisen at Umeå University has found links between the aquatic environment and the spreading of diseases such as tularaemia. The results indicate that aquatic environments act as “gyms” for bacteria, where the presence of predators train their defence against being killed and eaten up. The re...

You and I can help climate researchers in Abisko

2017-04-27
A new citizen science project in Abisko aims to teach the public how we do climate change science while collecting valuable data. CIRC researcher Keith Larson will receive nearly SEK 500,000 for an outreach project centred on the establishment of a research trail. This Formas grant is the second of ...

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...

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.
