Climate change and cyclic predator-prey population dynamics in the high Arctic.
International audience The high Arctic has the world's simplest terrestrial vertebrate predator–prey community, with the collared lemming being the single main prey of four predators, the snowy owl, the Arctic fox, the long-tailed skua, and the stoat. Using a 20-year-long time series of populat...

The latter change in particular is detrimental to the populations of the predators, which are adapted to make use of the years of the greatest prey abundance. Therefore, climate change will indirectly reduce the predators' reproductive success and population densities, and may ultimately lead to local extinction of some of the predator species. Based on these results, we conclude that the recent anomalous observations about lack of cyclic lemming dynamics in eastern Greenland may well be the first signs of a severe impact of climate change on the lemming–predator communities in Greenland and elsewhere in the high Arctic. 19 pages Article in Journal/Newspaper Alopex lagopus Arctic Fox Arctic Climate change Dicrostonyx groenlandicus Greenland Long-tailed Skua Mustela erminea Nyctea scandiaca snowy owl Stercorarius longicaudus Unknown Arctic Greenland |
