Ecological and zoogeographical groups of rove beetles (Staphylinidae, Coleoptera, Insecta) of Subalpine Belt of Northeastern macroslope of Ukrainian Carpathians

Abstract

The ecological and zoogeographical structure of rove beetles was analyzed in the biotope of crooked forest Pinus mugo Turra, 1764 of the Subalpine Belt of the North-Eastern macro-slope of the Ukrainian Carpathians. As a result of conducted study, the representatives of 24 species belonging to 19 genera and 10 subfamilies were detected within the biotope. The subfamilies Staphylinidae (25 %) which is characterized by the presence of representatives of 5 genera. The representatives of Ocypus genera (3 species), Atrecus, Emus, Philonthus, Quedius were identified within the studied biotope. Each of them was presented by the individuals of one species. A slightly lower number of identified species is typical for the Tachyporinae subfamily – 5 species belonging to the three genera Lordithon (1 species), Tachinus (2 species), Tachyporus (2 species). Subfamilies Omaliinae and Oxytelinae are presented by the genera Pycnoglypta, Omaliinae, Olophrum and Oxytelus, Anotylus, Deleaster. A part of subfamilies characterized by the presence of the representatives of only one species equals 50%. This group of subfamilies includes: Oxyporinae, Paederinae, Pselaphinae, Steninae, Xantholininae, Olistaerinae that are represented by one species. According to Margaleff and Mennicin a display number of the species abundance are rather high (4.19 and 1.60,). This aspect indicates a small number of eudominant and dominant species. Simpson index (0.09) indicates a significant diversity of representatives of subdomains and retsendents. The Berger Parker index is low (0.18) that indicates a minor quantity of representatives of the most numerous species – Pycnoglypta lurida (Gyllenhal, 1813). Staphylinidae group is characterized by the presence of representatives of four classes of domination (eudominants, dominants, subdominants and recedants) within the biotope of mountainous pines. The representatives of eudominants (Deleaster dichrous (Gravenhorst, 1802), Olophrum rotundicollе Sahlberg,1830 and Pycnoglypta lurida Gyll., 1813) and dominants (Emus hirtus Linnaeus, 1758, Tachinus elongatus Gyllenhal., 1810) groups form the centerpiece of the researched group. The groups of subdominants and recedants are characterized by a presence of representatives of 13 species and 6 species, respectively. As a result of analysis of ecological and morphological groups, it was revealed that the largest number of species belongs to a group of epibionts (58.34 %), borers (28.14 %), cryptobionts (12.51 %). A vast majority of species detected by trophic specialization are the predators (65 %). A slightly smaller number of species belongs to a group of micsophages that combine peculiarities of both nutrition predators and mycetophages or saprophages. According to area analysis, most of the detected species belong to the Holarctic and Palaearctic types of the zoogeographical zones.
