TL;DR: An overview of tundra species that exhibit population cycles is given and changes have already taken place in the dynamics of some key herbivores and their predators, consistent with the expected impacts of climate change.

TL;DR: It is shown that in Svalbard in the high Arctic, extreme weather events synchronize population fluctuations across an entire community of resident vertebrate herbivores and cause lagged correlations with the secondary consumer, the arctic fox.

TL;DR: It is indicated that most Arctic endemic species in Svalbard are experiencing negative consequences induced by the warming environment, and the tight relationships between the marine and terrestrial ecosystems in this High Arctic archipelago are emphasized.

TL;DR: The circumpolar arctic fox Alopex lagopus thrives in cold climates and has a high migration rate involving long-distance movements, which differs from many temperate taxa that were subjected to climate change.

TL;DR: Results presented here suggest that, through its influence on sea ice, vegetation, prey dynamics and distribution, continued arctic climate change may have effects as dramatic as those of the Pleistocene on the genetic structure of arctic canid species.
