Interspecific Killing of an Arctic Fox by a Red Fox at Prudhoe Bay, Alaska

ARCTIC, 2009
We report on the interspecific killing of an arctic fox ( Alopex lagopus ) by a red fox ( Vulpes vulpes ) in the Prudhoe Bay Oilfield, Alaska, an event that was captured on video in November 2004. Both the video and evidence from observation indicate that this may be a case of intraguild predation.

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 ...

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.

The naked fox: hypotrichosis in arctic foxes (Alopex lagopus)

Polar Biology, 2007
We describe the manifestations and occurrence of hypotrichosis in arctic foxes and compare it to the Samson character in red foxes. During 1979–2005, we collected carcasses of both normal and hypotrichotic arctic foxes from foxhunters in Iceland for macroscopic and microscopic examination and study of demography.

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
