Low levels of genetic differentiation and structure in red fox populations in Eastern Canada and implications for Arctic fox rabies propagation potential.

open access: yesPLoS ONE, 2023
Rabies is a lethal zoonosis present in most parts of the world which can be transmitted to humans through the bite from an infected mammalian reservoir host.

A battle of the mountains: Intraguild competition between arctic fox Vulpes lagopus and red fox Vulpes vulpes [PDF]

open access: yes, 2019
Fjellreven (Vulpes lagopus) er en truet art i Fennoskandia. Konkurranse med rødreven (Vulpes vulpes) er regnet som en av hovedtruslene for fjellrevens utbredelse. Flere bevaringstiltak har blitt satt i gang for å redde fjellreven, både støttefôring av fjellreven, uttak av rødrev og et avls- og reintroduksjonsprogram.

Predation patterns on the tundra—genetic barcoding of scats from two sympatric fox species

open access: yesArctic Science, 2023
In the Arctic tundra, climate-induced emergence of the red fox (Vulpes vulpes (Linnaeus, 1758)), a competitor to the Arctic fox (Vulpes lagopus (Linnaeus, 1758)), is predicted to influence predation patterns of both fox mesopredators.

Direct Interaction Between Roe Deer and Mountain Hare, a Case of Interference Encounter Competition? [PDF]

open access: yesEcol Evol
Here, we report on a case of direct interaction between a roe deer doe and a mountain hare recorded by a camera trap in Tydal Municipality, Norway, suggestive of direct interference competition. The roe deer doe is following and displacing the mountain hare for at least 2 min and 29 s, including a 19 s active phase.

Faecal Cortisol Metabolites as an Indicator of Adrenocortical Activity in Farmed Blue Foxes

open access: yesAnimals, 2021
Welfare studies of blue foxes would benefit from a measurement of faecal cortisol metabolites (FCMs) as a non-invasive, physiological stress parameter reflecting hypothalamus–pituitary–adrenal (HPA) axis activity.

Low vulnerability of Arctic fox dens to climate change-related geohazards on Bylot Island, Nunavut, Canada

open access: yesArctic Science, 2021
Climate change increases the risk of severe alterations to essential wildlife habitats. The Arctic fox (Vulpes lagopus (Linnaeus, 1758)) uses dens as shelters against cold temperatures and predators.

Ancient origin and genetic segregation of canine circovirus infecting arctic foxes (Vulpes lagopus) in Svalbard and red foxes (Vulpes vulpes) in Northern Norway [PDF]

open access: yes, 2021
Canine circovirus (CanineCV) is a relatively new viral species, belonging to the family Circoviridae, whose pathogenic role is still uncertain. Since its first description in one domestic dog in 2011 from the USA, several reports have been documenting ...

Molecular evolution of the leptin exon 3 in some species of the family Canidae

open access: yesGenetics Selection Evolution, 2003
The structure of the leptin gene seems to be well conserved. The polymorphism of this gene in four species belonging to the Canidae family (the dog (Canis familiaris) – 16 different breeds, the Chinese racoon dog (Nyctereutes procyonoides procyonoides ...

COMPARATIVE CHARACTERISTICS OF MESENTERIAL LYMPH NODES IN VULPES LAGOPUS

open access: yesScientific Notes Kazan Bauman State Academy of Veterinary Medicine, 2021
Lymph nodes are an active biological filters in which pathogens are retained and phagocy-tosed. Lymph nodules are dynamic structures of the lymph nodes. They form and disappear depend-ing on the presence of stress factors of various natures. The article presents the parameters of mes-enteric lymph nodes of carnivores in comparison with regional lymph ...

The alternative prey hypothesis revisited: Still valid for willow ptarmigan population dynamics.

open access: yesPLoS ONE, 2018
The alternative prey hypothesis predicts that the interaction between generalist predators and their main prey is a major driver of population dynamics of alternative prey species.
