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.

Red fox (Vulpes vulpes) as reservoir of parasites and source of zoonosis. This review presents data from Europe and Poland on the prevalence of helminth and protozoan parasites in red foxes (Vulpes vulpes). The most common nematodes were geohelminths: Uncinaria stenocephala, Toxocara canis and Toxocara leonina. As concerning Trichinella genus T. britovi was found more often than T. spiralis. Among tapeworms the following species were recorded: Mesocestoides lineatus, Taenia sp., and Echinococcus multilocularis. Detected cases of E. Multilocularis together with an increase of fox population during last few years create a potential human risk of infection. The results of many studies indicate rare presence of trematodes (Alaria alata) and protozoan parasites (Toxoplasma gondii, Neospora caninum, Leishmania spp., Eimeria spp.) in red foxes.

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.

The aim of the study (carried out 25 km south of Poznań, western Poland) was to determine the impact of Red Fox on bird abundance on farmland. Bird abundance was studied in the years 1999-2000 and 2005-2007 in three categories of sampling plots: 1) in small woods — with or without active fox dens, 2) along transects — starting from dens and running across arable land, and 3) around points — located at dens and far from them. Thus, variability in bird density was analyzed in relation to the presence/absence of Red Fox (in woods) and to the intensity of Red Fox penetration of crops (approximated by distance from a den). Two groups of bird species were distinguished with respect to their vulnerability to Red Fox predation pressure: 1) potential fox prey, i.e. species nesting on the ground and in low vegetation; and 2) birds not threatened by foxes, i.e. species nesting in tree holes and in tall vegetation. To investigate the relationships between bird distribution and Red Fox dens in woods, a step-wise multiple regression of bird density and species number on woodland structure was first performed. The residuals derived from the model were used to evaluate the impact of foxes by analyzing the differences between woods with and without active dens. Neither the species number nor the bird density differed significantly between woods with and without active dens. The differences in bird density observed between years in woods with or without active dens were not significant, either. No relationship between bird density in crop fields and distance from fox dens was found. The results are contrary to those of earlier studies and show that Red Fox does not affect farmland bird distribution, diversity and abundance, at least in the short term.

We examined dental anomalies, including oligodonty, polydonty, connation, rotation, and misalignment in 510 gray foxes and 150 red foxes from southern Illinois (USA). Dental anomalies were significantly more common (x 2 = 11.5, df = 1,p < 0.001) in gray foxes (n = 177; 34.7% of sample) than red foxes (n = 25; 16.6% of sample), and more common in male than female gray foxes (x 2 = 3.88, df = 1,p < 0.05). Polydonty was very uncommon, as expected for species in which the normal dental complement is close to the primitive eutherian number. In both species, the most prevalent anomaly was loss of the last lower molar. Loss of the upper or lower first premolar was also common. Thus, oligodonty almost always involved the smaller anterior (P1 and P1) or posterior (M3) teeth of the dental arcade. Conversely, the large carnassial teeth, with complex occlusal patterns and shearing surfaces, appeared to be highly conserved with only three anomalous individuals (0.4%) among all specimens.

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.
