COMPARATIVE CHARACTERISTICS OF THE FAUNA OF THE INSECTS OF THE COLEOPTERA ON THE MEADOWS-STEPE ARES OF THE NATIONAL PARK "KREMENETSKI HORY"

Abstract

The article establishes the patterns of transformation of the group of soil-litter of the Coleoptera in the meadow-steppe areas o the National Park "Kremenetski Hory", which are caused by the losts of the meadow steppes. The species composition of the ground-litter Coleoptera on the meadow-steppe habitats was analyzed in accordance with field research during 2019–2021 at the mountains Divochi skely, Sokilya and Volovytsia, as well as in the botanical reserve of national significance "Vakantsi".
Afforestation of the meadow-steppe habitats of the Kremenets Mountains almost completely destroyed them, and the remaining areas are localized as small "islands" far from each other, and their area is insignificant. The dominant species found on the territory of the Park are Carabus coriaceus and C. convexus, Abax parallelus, Nicrophorus interruptus, Leptura maculate, Gnaptor spinimanus (the highest number at the mountains Maslyatyn, Strahova) and Maladera holosericea occur with high regularity in the meadow-steppe areas. By comparing the soil-litter beetles in the meadow-steppe areas of the Park, Shannon's diversity index is 2.6, and Simpson's index is 0.8. The species of Coleoptera in the meadow-steppe areas differ significantly, the highest rate of species diversity is characteristic of the mountain of Sokillya and the botanical reserve "Vakantsi".
