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

Magnetization Ripple and Arctic Foxes

Journal of Applied Physics, 1965
A model of a polycrystalline magnetic film is considered in which the film is made up of transverse strips of (N) grains, with the magnetization M everywhere parallel within a strip but varying in direction from strip to strip. It is shown that the effective crystalline anisotropy in each strip can be represented by a transverse field Ht which varies ...

PARASITES OF THE ARCTIC FOX (ALOPEX LAGOPUS) IN ICELAND

Journal of Wildlife Diseases, 1993
Forty-four of 50 arctic foxes (Alopex lagopus) in Iceland harbored 15 species of intestinal parasites, including Protozoa: Eimeria sp. or Isospora sp. (in 4%); Trematoda: Cryptocotyle lingua (24%), Plagiorchis elegans (4%), Brachylaemus sp. (12%), Tristriata sp. (10%), and Spelotrema sp.

SOCIAL ORGANIZATION AND PARENTAL BEHAVIOR IN THE ARCTIC FOX

Journal of Mammalogy, 2000
Abstract We studied social organization and behavior of arctic foxes (Alopex lagopus) in 3 adjacent territories from 1988 to 1995 in central Norway, where the major rodent prey were cyclic. Twenty-five foxes were equipped with radiotransmitters and several other individuals could be recognized visually. Paired adult foxes and their cubs had home ranges

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

Arctic Fox Responses to Tourism Activity

The Journal of Wildlife Management, 2020
ABSTRACTAs the interest for nature‐based tourism activities increases, it is important to provide evidence‐based guidelines for wildlife‐human interactions to minimize the disturbance caused to wildlife. In Fennoscandia, the endangered arctic fox (Vulpes lagopus) is subject to increasing tourism interest and some regions recommend a minimum approach ...

Alopex lagopus (Arctic fox)

1973
Skin biopsies from one male and two female foxes from Greenland were used. The male had an apparent centric fusion of two acrocentric elements displayed as the last pair of autosomes.

RABIES AND THE ARCTIC FOX (VULPES LAGOPUS): A REVIEW

Journal of Wildlife Diseases
The Arctic fox (Vulpes lagopus) is the primary infection reservoir of Arctic rabies, the dynamics of which are poorly understood and subject to significant spatiotemporal variation. Although rabies presence has been documented in the region since the mid-19th century, there is currently no evidence of rabies impacting Arctic fox population size.

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
