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.

Common ravens raid arctic fox food caches

Journal of Ethology, 2006
Cache recovery is critical for evolution of hoarding behaviour, because the energy invested in caching may be lost if consumers other than the hoarders benefit from the cached food. By raiding food caches, animals may exploit the caching habits of others, that should respond by actively defending their caches.

Foraging Patterns of Arctic Foxes at a Large Arctic Goose Colony

ARCTIC, 2000
Arctic foxes ( Alopex lagopus ) are the main predators of many arctic-nesting birds, and such predation can have a large impact on the nesting performance of geese in some years and in some parts of the Arctic. We examined foraging patterns of arctic foxes at a large lesser snow goose ( Chen caerulescens caerulescens ) colony on Banks Island, Canada ...

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

Toxocara canis in experimentally infected silver and arctic foxes

Parasitology Research, 2005
In two experiments, thirty-six farm foxes of two species were inoculated with various doses of infective Toxocara canis eggs or tissue larvae isolated from mice. In experiment I, six adult arctic foxes (Alopex lagopus; 11-month old) were each inoculated with 20,000 eggs and sacrificed 100, 220, or 300 days post infection (dpi), while ten silver fox ...
