Cases of Pseudorabies in Free-Living Red Foxes (Vulpes Vulpes) and in Captive Blue Foxes (Alopex Lagopus) in Denmark [PDF]
Acta Veterinaria Scandinavica, 1969 In the period December 1967 through April 1969 eight spontaneous cases of pseudorabies in Danish red foxes were demonstrated by virus isolation. One fox had been kept in captivity, the remaining seven were free-living. Five of the foxes were found dead, while three, presenting abnormal behaviour when encountered, had been killed.

Veterinary Clinical Pathology, EarlyView.ABSTRACT A 1‐year‐old female‐intact arctic fox (Vulpes lagopus) presented for diarrhea, lethargy, severe thrombocytopenia, and hyperbilirubinemia. Blood film evaluation revealed intracytoplasmic coccoid bacteria within moderate numbers of leukocytes consistent with infection by a rickettsial organism.

Dynamics and persistence of rabies in the Arctic
Polar Research, 2019 Rabies is a major issue for human and animal health in the Arctic, yet little is known about its epidemiology. In particular, there is an ongoing debate regarding how Arctic rabies persists in its primary reservoir host, the Arctic fox (Vulpes lagopus ...

Zoo Biology, Volume 45, Issue 3, Page 266-279, May/June 2026.We distributed a survey to global institutions housing bush dogs (Speothos venaticus) to collect data on factors which may affect litter survival. Information from the Zoological Information Management System (ZIMS) and studbook records supplemented this dataset. We found that within northern temperate regions, the number of pups reared to the age of 1

The triangulation between Arctic birds, Arctic foxes and Arctic lemmings
Frontiers in Ecology and EvolutionMany studies have suggested that Arctic predators preying on lemmings, especially the Arctic fox, take advantage of the high prey densities during peak years, but have to switch to alternative prey during years of low lemming density, thereby forcing ...

Polar Research, 2017 The abundance and distribution of animals often vary dramatically among years in Arctic environments. Such variation, in turn, is closely related to changes in food abundance and its effect on vital rates such as survival and recruitment.

How potential competitors and predators affect arctic fox (Vulpes lagopus) behaviour at two types of foraging sites : experimental carcasses and exclusive feeding stations [PDF]
, 2021 Konkurranse er en velkjent økologisk mekanisme som oppstår når flere individer eller arter utnytter en begrenset ressurs. I den alpine tundraen er ressurstilgangen særlig lav, og den truede fjellreven (Vulpes lagopus) er en art som er preget av stadig ...
