abstract

With the advent of the golden jackal in the Lower Dnister, certain changes have taken place in natural complexes, which are primarily related to the impact of the new species on the local fauna. Under such conditions, the number of jackals in certain areas, the spatial structure and location of separate packs are important information for the development of measures aimed at maintaining an optimal abundance of this species. Given the active impact of wildlife on natural systems, there are a number of both biological and purely social problems that need to be addressed. The effectiveness of solving such problems directly depends on the level of study of various aspects of biology and ecology of jackals. In addition, knowledge of the current state of the Dniester jackal population allows timely and effective response to new environmental challenges, which are associated with an increase in the abundance of new species and in its impact on the native mammal fauna. The results of the research indicate a certain competition of the jackal with other species of predatory mammals, in particular the fox and the raccoon dog. Thus, within the territories where the study was carried out, with the appearance of the jackal at the lower course of the Dnister, the red fox was not observed at all and the number of raccoon dogs decreased significantly. Habitats of separate jackal groups within the Lower Dnister National Nature Park have been identified and their total abundance has been established. The dynamics of settlement by the species of the Lower Dnister area is analysed, the conservatism of the species in relation to the residential areas is indicated. It has been established that in some parts of the park, in particular on the northern bank of the Dnister Estuary, the density of animals is about 12 individuals per 1000 hectares, which significantly exceeds the permissible sanitary and epidemiological standards. At the same time, in some parts of the floodplains of the Lower Dnister, density exceeds 0.5 individuals per 1000 ha, which indicates a complex spatial distribution of separate packs and groups of jackals. Mapping of the number of jackals in the park showed that groups far from the estuary are smaller in number (614 individuals), whereas groups near the estuary are more abundant (1320 individuals).
