On the Coleoptera fauna of the planned national park

Abstract:

The aim of the research was to study landscape biodiversity of Altai Krai in order to monitor their state. The article provides the results of studying Coleoptera necrophilous complex in the pine wood "Kolyvansky borok" which is located in the area of the planned national park "Mountain Kolyvan", which is a standard of native vegetation of Altai-Sayansk mountain region. Samples were collected by means of soil traps with decaying fish as bait. 46 species from 10 Coleoptera families have been revealed. Staphylinidae (66.14%) dominated in species diversity and number, as for Leiodidae, Scarabaeidae and Silphidae, they were much less abundant (10.63%, 7.48% and 6.70% respectively). The percentage of other species families was about 9.50%. Rare species (score of abundance 1) predominated in the collections (71.74%). Only one dominant species, e.i. Aleochara curtula (score of abundance 4), was numerous (16.93% of the total number of species). It can be explained by closely located small settlements with abundance of substrates for the development of flies that Aleochara are associated with. Shannon index for the studied sites is 3.27, Berger Parker index amounted to 0.17 and Pielou index was 0.59 that shows high species diversity and poorly expressed domination at comparatively equal abundance of main species. In general, in the necrophilous Coleoptera fauna there are litter and substrate species which are characteristic for the region forest landscapes; there are also species common for anthropogenic landscapes (e.i. Creophylus maxilosus, Ontholestes murinus, Philonthus cruentatus, Ph. marginathus). It was noted that the abundance of some species is subjected to recreation pressure.
