| Abstract [eng] |
The diet composition of red fox (Vulpes vulpes L.), raccoon dog (Nyctereutes procyonoides Grey.), using stomach analysis, and the morphometrical differences of red fox (Vulpes vulpes L.) were studied in Lithuania. Forty-three males and twenty-eight females of red fox were measured at the 5 measurement points. Furthermore, eighty eight red foxes and forty one raccoon dog skulls were measured at the 16 measurement points, mandibles at the 3 measurement points.5 statistically significant differences in measurements of red fox body were obtained between males and females. Eight skulls and one mandible features of the male foxes were statistically significantly longer compared to the same females foxes features. Five statistically significant differences were found between skull measurement point and one statistically significant difference between mandible measurement points of raccoon dog. Furthermore fifteen significant differences were found between measurements in males and fourteen between measurements in females. The frequency of occurrence and relative capacity were evaluated. In the cold season (November-February), small mammals and carrion of ungulates was the principal food of both predator species. For the raccoon dog plants were an important food component too. |
