Evidence of Arctic Fox (Vulpes lagopus) Survival Following Exposure to Rabies Virus

Journal of Wildlife Diseases, 2022
The arctic fox variant of the rabies virus (RABV) is enzootic in the circumpolar north. Reports of abortive RABV exposures motivated a retrospective analysis of sera from 41 arctic foxes (Vulpes lagopus) captured at Karrak Lake in Nunavut, Canada, during 2011-15. Estimated RABV antibody prevalence among foxes was 15% (95% confidence interval, 7-28%).

Analysis of sperm chromatin structure in blue foxes (Alopex lagopus) and silver foxes (Vulpes vulpes)

Livestock Science, 2020
Abstract The latest reports indicate that sperm function is significantly influenced by the chromatin structure of the sperm and the integrity of its DNA. The aim of the study was to determine the level of condensation in the chromatin structure of fresh semen and the degree of damage to the DNA chain in fresh and chilled semen of farmed blue and ...

Disentangling long bones of foxes (Vulpes vulpes and Alopex lagopus) from arctic archaeological sites

Journal of Archaeological Science, 2010
To discern the presence of two anatomically close species within an archaeological assemblage is always a problem for the analyst. A particularly interesting case is the distinction between the red fox (Vulpes vulpes) and the arctic fox (Alopex lagopus), which is often determined using non-rigorous criteria and producing results that must be regarded ...

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.

Breeding for better eye health in Finnish blue fox (Vulpes lagopus)

Journal of Animal Breeding and Genetics, 2015
SummaryThe frequency of eye infections in the Finnish blue fox population has increased during the past decade. Eye infection may incur economic losses to producers due to reduced selection intensity, but ethical aspects need to be considered as well because eye infection can be quite painful and reduce animal well‐being.

Retinal photoreceptor and ganglion cell types and topographies in the red fox (Vulpes vulpes) and Arctic fox (Vulpes lagopus).

The Journal of comparative neurology, 2018
The red fox (Vulpes vulpes) is the carnivore with the widest distribution in the world. Not much is known about the visual system of these predominantly forest-dwelling animals. The closely related Arctic fox (Vulpes lagopus) lives in more open tundra habitats. In search for corresponding adaptations, we examined the photoreceptors and retinal ganglion

Preference for various nest box designs in farmed silver foxes (Vulpes vulpes) and blue foxes (Alopex lagopus)

Applied Animal Behaviour Science, 2000
Nest box choice experiments were carried out outside the breeding season on adult silver and blue fox vixens with no previous permanent nest box experience. Nest boxes were varied in height of placement, number of rooms, presence of entrance room or platform and light conditions. Only one parameter was varied in any one experiment.

First isolate of Toxoplasma gondii from arctic fox (Vulpes lagopus) from Svalbard

Veterinary Parasitology, 2008
Cats are considered essential for the maintenance of Toxoplasma gondii in nature. However, T. gondii infection has been reported in arctic fox (Vulpes lagopus) from the Svalbard high arctic archipelago where felids are virtually absent. To identify the potential source of T. gondii, we attempted to isolate and genetically characterize the parasite from

Milk intake in blue fox (Alopex lagopus) and silver fox (Vulpes vulpes) cubs in the early suckling period

Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2000
Milk intake of fox cubs (2-16 days of age; body weight, 96-649 g) in ten blue fox litters and ten silver fox litters were measured by the water isotope dilution (WID) technique following a single intraperitoneal injection of tritiated water (3HHO). Litter size varied from four to 14 in blue foxes and from three to eight in silver foxes. Silver fox cubs
