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.

Cloning and Spatiotemporal Expression Analysis of <i>IGF1R</i> Gene cDNA in <i>Alopex lagopus</i> (Arctic Fox). [PDF]
Life (Basel)This 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 ...

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. The body length was at the maximum part of the range. In 1982, a very large male arctic fox was observed in the same area.

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 of arctic predators under such circumstances may be very instructive since rodent cycles have been ...

Space Use of an Expanding Generalist Predator Is Shaped by Human, Marine and Seasonal Effects on Arctic Tundra. [PDF]
Ecol EvolGeneralist species that benefit from human impacts on terrestrial ecosystems and expand their distribution range can threaten biodiversity by outcompeting or predating on native specialists.

What does the fox say? Arctic fox vocalization and associated den behaviours
Polar ResearchFoxes (Vulpes spp.) are small, solitary canids with relatively low social complexity compared to more gregarious canids, such as wolves and dogs. They are, therefore, expected to have a relatively simple vocal repertoire, with limited low-intensity sounds for close communication and many high-intensity sounds for long-distance communication.

Predation patterns on the tundra—genetic barcoding of scats from two sympatric fox species
Arctic Science, 2023 In the Arctic tundra, climate-induced emergence of the red fox (Vulpes vulpes (Linnaeus, 1758)), a competitor to the Arctic fox (Vulpes lagopus (Linnaeus, 1758)), is predicted to influence predation patterns of both fox mesopredators.

Morbillivirus-associated lipid pneumonia in Arctic foxes [PDF]
Journal of Veterinary Diagnostic Investigation, 2018 We describe lipid pneumonia in 5 of 24 Arctic foxes ( Vulpes lagopus) in association with morbillivirus infection, and lymphoid depletion in 3 of these 5 foxes. Canine distemper virus (CDV) immunohistochemistry yielded positive staining in lung, lymph nodes, spleen, adipose tissue, and renal pelvic urothelial cells in 5 cases.

Were ancient foxes far more carnivorous than recent ones?-Carnassial morphological evidence.
PLoS ONE, 2020 Crown shape variation of the first lower molar in the arctic (Vulpes lagopus) and red foxes (Vulpes vulpes) was analyzed using five groups of morphotypes.
