10,000 year-old DNA proves when fish colonialized our lakes

2017-09-20
DNA in lake sediment forms a natural archive displaying when various fish species colonized lakes after the glacial period. 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.

Reindeer grazing protects tundra plant diversity in a warming climate

2017-09-04
Climate warming reduces the number of plant species in the tundra, but plant-eating animals, such as reindeer and voles, can turn this negative effect into something positive. The results of a study coordinated from Umeå University in Sweden are now published in Nature Communications.

Climatic stability resulted in the evolution of more bird species

2017-07-17
More species of birds have accumulated in genera inhabiting climatically stable areas. This is shown by a new study from Umeå University.

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...
