Research Alert
1. Researchers conducted a comprehensive overview of projects monitoring lemmings—a key component of tundra food webs—and found that since 2000, lemmings have been monitored at 49 sites circumpolar Arctic, of which 38 are still active.
2. Researchers are monitoring for abundance at all sites, but health, genetic diversity and potential drivers of population change, were often not monitored.
3. There was no evidence that lemming populations were decreasing in general, although a negative trend was detected for low arctic populations sympatric with voles.
