A behavioral audiogram of the red fox (Vulpes vulpes)
Hearing Research, 2015We determined the absolute hearing sensitivity of the red fox (Vulpes vulpes) using an adapted standard psychoacoustic procedure. The animals were tested in a reward-based go/no-go procedure in a semi-anechoic chamber. At 60 dB sound pressure level (SPL) (re 20 μPa) red foxes perceive pure tones between 51 Hz and 48 kHz, spanning 9.84 octaves with a ...

Helminths of red foxes (Vulpes vulpes) in Denmark
Veterinary Parasitology, 2006An epidemiological study of helminths in 1040 red foxes collected from various localities in Denmark during 1997-2002, revealed 21 helminth species at autopsy, including nine nematode species: Capillaria plica (prevalence 80.5%), Capillaria aerophila (74.1%), Crenosoma vulpis (17.4%), Angiostrongylus vasorum (48.6% from Northern Zealand (endemic area)),

Experimental infection of red foxes (Vulpes vulpes) with Sarcoptes scabiei var. vulpes
Veterinary Parasitology, 1984Two of 3 red foxes became experimentally infected with Sarcoptes scabiei v. vulpes isolated from a naturally infected wild fox. The first clinical sign was seen after 10 days. After 30 days hairless patches were observed on the back of one of the foxes while general hair loss continued slowly.

1974
The X chromosome is identifiable because it is the largest chromosome with highly unequal arm ratio. The identification of the Y is subjective because the two “microchromosome”-like autosomes are of similar size. It is also questionable whether the Y is biarmed.

Trichinella spiralis in the Red Fox (Vulpes vulpes) in Ireland
Nature, 1969SINCE 1835 when Owen1 described the species Trichinella spiralis from man in London, trichinosis has occurred occasionally, sometimes in epidemics, in both Britain and Ireland as well as being endemic in some parts of the world. While infection in wildlife has been reported in at least sixty-five species of mammal2, the primary reservoirs are ...

Reproductive management of silver foxes (Vulpes vulpes) in captivity
Theriogenology, 2000Specific protocols need to be developed that take into consideration the requirements of silver foxes. This study was designed to investigate the reproduction of 26 pairs of silver foxes (Vulpes vulpes). Reproduction parameters (breeding season, age at puberty, fecundity and fertility) of the foxes were examined under experimental conditions, and new ...

Acute Disseminated Toxoplasmosis in a Red Fox (Vulpes vulpes)
Journal of Wildlife Diseases, 1990A red fox (Vulpes vulpes) with signs of neurological disease was captured in Fairmount Park, Philadelphia, Pennsylvania (USA). The animal died in captivity and was examined because of suspected rabies. The liver had pale foci up to 4 mm in diameter. Foci of necrosis were associated with Toxoplasma gondii tachyzoites in several organs including liver ...

Genetics of Interactive Behavior in Silver Foxes (Vulpes vulpes)
Behavior Genetics, 2016Individuals involved in a social interaction exhibit different behavioral traits that, in combination, form the individual's behavioral responses. Selectively bred strains of silver foxes (Vulpes vulpes) demonstrate markedly different behaviors in their response to humans.

Variations of the chromosome number in the red fox (Vulpes vulpes)
Chromosoma, 1971The chromosome number in peripheral blood cells of five individuals of Vulpes vulpes (Red Fox) is shown to vary between 35 and 39. This variation is due to loss or gain of the smallest autosome, which it is suggested is heterochromatic and does not have any major influence on the phenotype.
