The number of lemmings (Lemmus lemmus) in the mountains can fluctuate sharply from one year to the next. Years when populations explode are called lemming years. These population explosions are ...

The researchers also identified hundreds of mutations unique to the Norwegian lemming, particularly in genes related to coat color, fat metabolism, and possibly even behavior. These genomic ...

This news release is also available in French. New findings suggest that a special combination of predators can drive lemming populations through a four-year boom and bust cycle, which has been one of ...

Using whole genome sequencing and cutting-edge analyses researchers at Stockholm University have uncovered the surprising evolutionary history of the Norwegian lemming (Lemmus lemmus), revealing it to ...

Research shows a decline in lemming populations due to warmer winters, disrupting ecosystem dynamics and predator-prey relationships. Lemming populations throughout Scandinavia tend to explode ...

Learn more about how genetic research reveals the Norwegian lemming only split from its Siberian cousin 35,000 years ago. New research has revealed that the Norwegian lemming is one of the youngest ...

New research has revealed that the Norwegian lemming is one of the youngest mammals on Earth. The team found that the Norwegian lemming split from its closest relative, the Western Siberian lemming, ...
