Limnology and Oceanography Research Exchange (LOREX) is an NSF funded initiative to provide training in international research for graduate students. Graduate student research is often constrained by the resources, ideas, and culture of the home institution. International collaborations enhance graduate students’ ability to think critically and creatively, make cross-disciplinary connections, and stretch one's field of view while gaining competency in an international environment and increasing their network of colleagues.

Opportunities for research exchanges in freshwater ecology, aquatic biogeochemistry and paleolimnology are possible with CIRC at Umeå University.

Arctic worming?

[2018-02-16] 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.

Journal of Ecology (The Blog): Winter is coming but is getting warmer!

Winter is coming but is getting warmer!


This new video podcast from Eveline Krab is dedicated to winter ecology and shows that climate warming is also happening in winter! In this video, Eveline highlights the main results of her paper recently accepted for publication in Journal of Ecology titled “Winter warming effects on tundra shrub performance are species-specific and dependent on spring conditions“.

Eveline’s video can also be found on the Journal of Ecology YouTube channel (English subtitles available).
