Arctic foxes

2004
AbstractThis chapter examines the life history characteristics of two Arctic fox populations, a relatively stable one in Iceland and a fluctuating one in Sweden. Intraspecific variation in reproductive and social strategies of Arctic foxes in Sweden and Iceland suggests that adaptations to different resource distributions in have resulted in divergence

Coasts of Foxe Basin, Arctic Canada

Geological Society, London, Special Publications, 2014
Abstract Foxe Basin is a down-faulted arctic basin floored by Palaeozoic carbonates, surrounded by metamorphic Precambrian terrains. Quaternary deposits consist of Pleistocene–Holocene glacial drift, and frost-shattered bedrock-clasts mostly reworked by sea waves during post-glacial emergence during the last 5000–6000 yr.

Alopex lagopus (Arctic fox)

RABIES IN THE ARCTIC FOX POPULATION, SVALBARD, NORWAY

Journal of Wildlife Diseases, 2011
Arctic foxes, 620 that were trapped and 22 found dead on Svalbard, Norway (1996-2004), as well as 10 foxes trapped in Nenets, North-West Russia (1999), were tested for rabies virus antigen in brain tissue by standard direct fluorescent antibody test. Rabies antigen was found in two foxes from Svalbard and in three from Russia. Blood samples from 515 of

Plasma Marking of Arctic Foxes with lophenoxic Acid

Journal of Wildlife Diseases, 1987
Six arctic foxes (Alopex lagopus) were marked with iophenoxic acid (IA), a substance which elevates concentrations of protein-bound iodine in blood plasma. Buccal absorption of IA was determined by placing 20 mg IA dissolved in 100% ethyl alcohol on the tongue. Blood samples collected from 1 to 36 wk following exposure showed that all foxes were marked

JUVENILE RICKETS AND HYPERPARATHYROIDISM IN THE ARCTIC FOX

Journal of Wildlife Diseases, 1979
Three of seven Arctic fox kits, Alopex lagopus, trapped on St. Paul Island, Alaska, had evidence of rickets and hyperparathyroidism. Radiographic, morphologic and histologic examination confirmed the diagnosis. The disease was presumed to be a juvenile-onset disease due to calcium-deficient intake following weaning.

Arctic fox versus red fox in the warming Arctic: four decades of den surveys in north Yukon

Polar Biology, 2012
During the last century, the red fox (Vulpes vulpes) has expanded its distribution into the Arctic, where it competes with the arctic fox (Vulpes lagopus), an ecologically similar tundra predator. The red fox expansion correlates with climate warming, and the ultimate determinant of the outcome of the competition between the two species is hypothesized

Arctic fox denning behavior in northern Alaska

Canadian Journal of Zoology, 1984
The behavior of nine families of denning arctic foxes was studied from blinds erected near occupied dens from June to August 1976 in the Prudhoe Bay area and from June to August 1978 and 1979 in the Colville River Delta area of northern Alaska. Six hundred and forty-eight hours of data representing 27 continuous 24-h observation periods were analyzed.
