The stomach contents of 41 Arctic foxes (Vulpes lagopus) killed during winter and spring (December to June 1991–93) on Disko Island were examined. Fish, seabirds and marine invertebrates were found to be the most important winter food for Arctic foxes on Disko Island. Most fish remains in the stomachs were identified as capelin (Mallotus villosus), and cached fish appear to be important winter food for coastal foxes in the Disko Bay area. The stomachs of blue foxes contained more fish and…

Fine-scale population genetic structure of arctic foxes (Vulpes lagopus) in the High Arctic
TLDR
The cryptic genetic subdivisions found in a population in the High Arctic may highlight ecological processes deserving further investigations in arctic foxes at larger, regional spatial scales.
Age-dependent genetic structure of arctic foxes in Svalbard
TLDR
Genotypes at 12 microsatellite loci for 561 arctic foxes trapped in the high-arctic archipelago Svalbard are analyzed and indicate a possible kin structure among adult females, suggesting natal philopatry, but further investigations will be needed to reach firm conclusions concerning kin structure.
Pulses of movement across the sea ice: population connectivity and temporal genetic structure in the arctic fox
TLDR
The lemming cycle is likely an important factor shaping Arctic fox movement across sea ice and the subsequent population genetic structure, but is also likely to influence local adaptation to the coastal habitat and the prevalence of diseases.
Arctic fox Vulpes lagopus population structure : circumpolar patterns and processes
Movement is a prominent process shaping genetic population structure. In many northern mammal species, population structure is formed by geographic distance, geographical barriers and various…
Evolution, ecology and conservation—revisiting three decades of Arctic fox population genetic research
TLDR
Pronounced intra-specific ecological variation makes the Arctic fox an ideal study organism for population genetic processes and the emergence of functional genomics will generate an even deeper understanding of evolution, ecology and conservation issues for several species.
Fitness and fur colouration - testing the camouflage and thermoregulation hypotheses in an Arctic mammal.
TLDR
This field study provides the first evidence for an effect of colour morph on the reproductive performance of Arctic foxes under natural conditions, with a higher breeding propensity of the blue morph compared to the white one, and suggests an advantage of the dark morph not directly related to disruptive selection by crypsis or thermoregulation.
Many species of the Carnivora consume grass and other fibrous plant tissues
TLDR
Deliberate ingestion of FPT may be more widespread and important than previously realized in the Carnivora, suggesting these abrasive or hairy plant tissues help to expel intestinal parasites.
Spatiotemporal distribution of rabies in Arctic foxes in Greenland
The temporal occurrence, spatial distribution, spread, and prevalence of rabies in Arctic foxes, Vulpes lagopus, in Greenland were studied using historical observations from 1969 to 2011 and survey…

Arctic fox (Alopex lagopus) diet in Karupelv valley, East Greenland, during a summer with low lemming density
TLDR
The existence of arctic foxes in East Greenland is dependent on regular peak years in lemming density, and within prey categories, lemmings were significantly more represented in the inland area, while the coastal area had a more diverse diet overall.
Food Habits of Arctic Foxes ( Alopex Lagopus ) on the Western Coast of Svalbard
Food habits of arctic foxes ( Alopex lagopus ) on the western coast of Svalbard were studied in the years 1986-89. Faeces (n=1018) were collected mostly in summer, and food remains were recorded both…
The behavioural ecology of the Arctic fox (Alopex lagopus) in Iceland
TLDR
The Arctic foxes were found to occupy well defined, but fairly flexible group territories, whose borders were advertised by olfactory, auditory and visual signals, and there was an indication that territories were larger in inland habitats.
Predation of ringed seal pups (Phoca hispida) by the arctic fox (Alopex lagopus)
The arctic fox (Alopex lagopus), commonly assigned the role of scavenger of marine mammal remains left by polar hears (Ursus maritimus), is for the first time quantitatively described as an important…
Notes on the food habits of Arctic foxes in northern Alaska
TLDR
Food habits of white foxes were studied on the Teshekpuk Lake Section of the Arctic Coastal Plain, northern Alaska from September 1961 through May 1963 to reflect the scarcity of suitable fox foods.
FOOD HABITS OF ALEUTIAN ISLAND ARCTIC FOXES
TLDR
The year around abundance of the intertidal food resources appears to buffer the foxes against winter starvation and may help to sustain high quality prey for Arctic foxes.
Diet of Arctic Foxes (Alopex lagopus) in Greenland
TLDR
Foxes caught in the more remote districts of Greenland seem less dependent on waste and garbage; they feed on a broad variety of food items according to the local diversity of the prey fauna.
Fluctuating Resources and the Evolution of Litter Size in the Arctic Fox
TLDR
It is suggested that litter size in the arctic fox is determined by the combined effect of immediate resource levels and the degree of resource predictability, and reaction norms are described that suggest how litter sizes result from adaptive plasticity within each of two genetic strategies where populations with unpredictable food resources generally have larger litter sizes.
Occurrence and distribution of king eiders Somateria spectabilis and common eiders S. mollissima at Disko, West Greenland
King eiders and common eiders were recorded at Disko Island, West Greenland, in the period 1989-1993. Both species occur year-round in the area, although in low numbers during the period of extensive…
Functional and numerical responses of four lemming predators in high arctic Greenland
TLDR
According to their specific functional and numerical responses, each predator plays a key role at some point of the lemming cycle, but only the stoat has the potential to drive the leMming cycle.
