Notes on a large Arctic fox scull
Fauna Norvegica, 1985 A female arctic fox Alopex lagopus was found dead on 23 June 1984 in Jämtland, Sweden. Upon measuring her skull, it turned out to be notably larger than reported for arctic foxes in the literature.

Genetic structure of immunologically associated candidate genes suggests arctic rabies variants exert differential selection in arctic fox populations. [PDF]
PLoS ONE, 2021 Patterns of local adaptation can emerge in response to the selective pressures diseases exert on host populations as reflected in increased frequencies of respective, advantageous genotypes.

Global Warming and effects on the Arctic Fox
Science Progress, 2008 We predict the effect of global warming on the arctic fox, the only endemic terrestrial predatory mammals in the arctic region. We emphasize the difference between coastal and inland arctic fox populations. Inland foxes rely on peak abundance of lemming prey to sustain viable populations.

Cloning and Spatiotemporal Expression Analysis of IGF1R Gene cDNA in Alopex lagopus (Arctic Fox) [PDF]
LifeThis study aimed to clarify the sequence characteristics and spatiotemporal expression patterns of the insulin-like growth factor 1 receptor (IGF1R) gene in Alopex lagopus (Arctic fox), thereby addressing the existing knowledge gap regarding IGF1R ...

The triangulation between Arctic birds, Arctic foxes and Arctic lemmings
Frontiers in Ecology and EvolutionMany studies have suggested that Arctic predators preying on lemmings, especially the Arctic fox, take advantage of the high prey densities during peak years, but have to switch to alternative prey during years of low lemming density, thereby forcing ...

Rough-legged buzzards, Arctic foxes and red foxes in a tundra ecosystem without rodents.
PLoS ONE, 2015 Small rodents with multi-annual population cycles strongly influence the dynamics of food webs, and in particular predator-prey interactions, across most of the tundra biome. Rodents are however absent from some arctic islands, and studies on performance
