Where are the hotspots of plant diversity along boreal streams?

2015-03-19
The patterns of plant species diversity along Swedish boreal streams are closely linked to flow of surface and sub-surface water. The linkages between vegetation and hydrology are tight, and according to Lenka Kuglerová they are threatened by poorly designed forest management. She defends her thesi...

Neither more food nor better food – still fish biomass increases

2015-03-11
To increase the biomass of fish, contemporary ecological theory predicts that either the amount of food or the quality of the food has to increase. In a recent experiment, researchers at Umeå University doubled the fish biomass under identical food supply and food quality by only controlling how muc...

Climate change influences the distribution of organic pollutants in the Baltic Sea

2015-02-18
Regional climate change models predict an increased freshwater runoff into the Baltic Sea. This will result in increased inflow of terrestrial dissolved organic carbon. According to Matyas Ripszam, Umeå University, this change will have high impact on the organic pollutants on the organic pollutants...

Climate change can cause loss of important ice dynamics in streams

2015-02-16
In her thesis, Lovisa Lind shows that ice and winter floods are important natural disturbances for maintaining species-rich riparian zones along northern watercourses. If the climate becomes warmer this disturbance might be lost. This could potentially lead to a less diverse riparian zone. She defen...

VA: Swedish children to help climate scientists by burying teabags

2015-02-09
Is it possible to read the future in tea leaves? This is what scientists at Umeå University are hoping to find out and they are now looking for school classes across Sweden to participate in a mass experiment that will help to inform climate change research. The so-called ‘Teabag Experiment’ is part...

2015-01-22
Dolly Jørgensen, historian and researcher at the Department of Ecology and Environmental Sciences, is guest blogging for Curie, a Swedish web magazine devoted to the world of research. She is going to take readers on ”An Expedition into the Heart of the Humanities."

Water-polluting anxiety drug reduces fish mortality

2014-08-08
A drug that is commonly used to treat anxiety in humans and which regularly finds its way into surface waters through wastewater effluence has been shown to reduce mortality rates in fish.

Three Umeå researchers receive Royal Scholarship for Science, Technology and the Environment

2014-05-06
Three of the 14 scholarships recipients this year from the King Carl XVI Gustaf 50th Anniversary Fund for Science, Technology and the Environment are young researchers at Umeå University: ecologists Jenny Ash and Anouschka Hof, as well as chemist Stina Jansson.

Scientific American podcast: Swedish Spruce Is World's Oldest Tree

2014-05-05
Leif Kullman, Professor of Physical Geography at Umeå University, along with fellow researchers, found the tree growing amid the remains of four generations of spruce dating from 375 to well over 9,000 years old. Researchers are excited about having a long case study of how past climate changes affe...

Extinctions reduce speciation

2014-04-04
The same factors that increase the risk of species extinctions also reduce the chance that new species are formed. This is concluded by two biologists at Umeå University. Their findings are published in the April issue of the scientific journal Evolution.
