Cases of spontaneous interbreeding of wolf and domestic dog in the region of Southeast Banat

The study presents the first documented data indicating the occurrence of spontaneous interbreeding of wolf and domestic dog in nature on the territory of Serbia, based on three specimens originating from the region of Southeast Banat. Some unique morpho-anatomical malformations of the cranium in two specimens are described. Based on complex morphological and craniometrical analysis of hybrid specimens and comparison with the corresponding material of authentic wolves from this region, it is possible to follow a local process of multiple wolf/dog hybridization and disturbance of the authentic genetic structure of wolf. The identification of wolf/dog hybrids is a subject of primary concern for the development of conservation and management strategies. Because of great vulnerability of the population of South-Carpathian wolves on the boundaries of their range in Serbia, there is a need for permanent and increased protection in order to maintain their adequately strong population in this region.
