The sample of 1453 specimens of the red fox Vulpes vulpes (Linnaeus, 1758) from Poland was analysed from the point of view of the presence and frequency of congenital dental abnormalities. Deviations from the steady dental pattern were found in 196 specimens (56 females, 100 males and 40 specimens of unknown sex). Together 230 cases of' anomalies were classified to eight different categories of dental abnormalities. The most frequent anomalies were: oligodonties (7.2%; leaving out those of M3 - 2.8%). The frequencies of the remaining categories were the following: deviations from the typical shape of the tooth - 2.5%, hypoplastic changes of the tooth enamel - 2.5%, presence of extra roots - 2.0%, polidonties - 2.0%, irregularities in the position of the teeth - 1.9%, partial split of the crown - 1.4%, partial eruption of the teeth - 0.7%. The frequency of the dental abnormalities was significantly higher (p < 0.05) in males (15.7%) than females (10.5%). Six out of eight categories of the dental abnormalities, ie: oligodonty, polidonty, partial split of the crown, partial eruption of the teeth, deviations from the typical shape of the tooth and irregularities in the position of the teeth, were insignificantly more frequent in males, Additional roots were found equally often among males as females, while enamel hypoplasias occurred insignificantly more frequently among females than among males. The examples of the dental anomalies observed in red fox indicated that in many cases they did not result from the influence of a single factor but they were the effect of a combined operation two or more factors of both genetic and environmental nature.

The studies aimed to evaluate the pathomorphological changes induced by various management conditions in arctic foxes. Healthy pups aged about eight weeks were randomly assigned to two groups, 20 animals each. The foxes of the control group were housed on a farm, while the experimental group comprised of foxes raised in a confined space. Throughout the rearing period, air quality monitoring of the environment of both groups was performed. During the autumn slaughter (the experiment lasted for 7 months), sections of the liver, kidneys, lungs, ovaries, and uterus obtained from all the foxes were evaluated pathomorphologically. Pathological changes were observed in lung sections collected from the animals of the experimental group. During the air monitoring, higher concentrations of pollutants were identified in the experimental group environment.

In this study we determined the levels of trace elements (zinc, copper, lead, cadmium and mercury) in three layers of bones of the hip joint (cartilage, compact bone and spongy bone) of 30 red foxes (Vulpes vulpes) from north-western Poland. Concentrations of Cu, Zn, Pb and Cd were determined by atomic absorption spectrophotometry (ICP-AES) in inductively coupled argon plasma using a Perkin-Elmer Optima 2000 DV. Determination of Hg concentration was performed by atomic absorption spectroscopy. In cartilage, compact bone and spongy bone samples from the red fox, median concentrations of the metals studied could be arranged in the following descending series: Zn > Cu > Pb > Cd > Hg, the values ranging from 142 to 0.002 mg/kg dw. There was a significant difference in Cu concentrations, among all the materials analyzed, with much more Cu found in spongy bone than in compact bone. Significant differences were also noted in the case of Hg concentrations in cartilage with compact bone and the spongy bone, and between concentrations of this metal in compact bone and spongy bone. In males, the concentration of Hg in spongy bone was greater than in females. Younger foxes had a higher concentration of this metal in cartilage than adults. The strongest synergistic relationships were observed in spongy bone between the Zn and Cu, Zn and Cd, as well as between Cu and Cd. Statistically significant antagonistic relationships were detected between zinc and lead in compact bone. In addition to monitoring studies conducted on the abiotic environment, an urgent need exists for long-term monitoring of concentrations of heavy metals with long-term effects on living organisms. An important addition is provided by biomonitoring studies on domesticated and free-living mammals, including Canidae.

Immunogenicity of six strains of Trichophyton mentagrophytes var. granulosum isolated from arctic foxes with ringworm was evaluated in guinea pigs and foxes. Two strains of T. mentagrophytes (Tm-3 and Tm-4) out of six examined (Tm- 1, Tm-2, Tm-3, Tm-4, Tm-5 and Tm-6) induced in the experimental foxes a strong cellular immune response measured by the leukocyte migration inhibition test (LMIT), lymphocyte transformation test (LTT), and by skin delayed-type hypersensitivity (DTH). The guinea pigs immunised with Tm-3 and Tm-4 were well protected against the artificial infection with the virulent strain of T. mentagrophytes (Tm-9). These two strains of T. mentagrophytes with high immunogenic properties were used for production of a vaccine against ringworm in foxes.

Red fox Vulpes vulpes (Linnaeus, 1758) are generally regarded as strictly territorial animals, inhabiting distinct and well-separated ranges. The home ranges of these predators can vary in size from a few dozen hectares to as much as 20-30 km2. Because it seemed impossible that foxes could defend areas so different in size with the same intensity, the published data were analysed in order to see how changes in home range size could affect the following parameters: home range overlap, the area visited daily and the distance travelled by animals during 24 h. It was found that the overlap between fox families (groups) occupying large ranges was much greater than between foxes living in small ranges. The ratio of the area visited daily to the seasonal home range size was greater in small ranges than in large ones. No significant correlation was found between the mean distance moved daily and home range size (r = -0.118, p = 0.75). These results suggest different patterns of the use of space and differences in territorial defence by red foxes inhabiting large and small ranges. The implications of home range overlap and intensity of contacts between foxes occupying neighbouring ranges for the spread of disease are discussed. The significant overlap between large ranges found in this paper is discussed in the light of Andrzejewski's (2002) home range concept.
