Abstract
During hundreds of years, in large cities man has been forming a specific urban environment with original species composition of insect communities, including the most diverse group of predatory beetles – Staphylinidae family. Kyiv, Kharkiv, Dnipro are the three most populated cities of Ukraine. In the urban cenoses of these cities, over 140 species from 66 genera of Staphylinidae have been recorded. The total of 69 species (43 genera) were recorded in Kyiv, 67 (39 genera) in Dnipro and 66 (37 genera) in Kharkiv. Among them, , eight species in the catalogue of Palearctic staphylinds had not been previously recorded for Ukraine: Arpedium quadrum Grav., Atheta laticeps Thomson, Medon apicalis Kraatz, Ocalea rivularis Müll., Philonthus salinus Kiesenwetter, Quedius invreae Gridelli, Tasgius pedator Grav. and Xantholinus gallicus Coiffait. By number, common species accounted for 29 in Dnipro, 21 in Kyiv and 19 in Kharkiv. In all the metropolises, two species (Staphylinus caesareus Cederhjelm and Drusilla canaliculata (F.)) were identified as eudominants. Dominants and subdominants comprised 18–25 species. Almost two thirds of the fauna of staphylinids of the cities was classified as rare species. The lowest faunistic similarity was seen between the staphylinids of the urban cenoses of Dnipro and those in Kyiv and Kharkiv (15.3% and 17.5%), similarity was higher for Staphylinidae of Kyiv and Kharkiv (36.0%). Similarity by common species of staphylinids for Kyiv and Kharkiv equaled 73.9%, 28.2% for Dnipro and Kyiv and 37.1% for Dnipro and Kharkiv. The article offers a review of species diversity, number and ecological structure (biotopic confinedness, hygrothermal preference) of typical species of staphylinids in different urban cenoses of Kharkiv. Differences in qualitative-quantitative and ecological structures of staphylinids are related to the diversity of the conditions in a particular urban cenoses. The commonest representatives of the family in the metropolises were polytopic mesophilous carnivorous species.
Highlights
The most important representatives of natural and transformed bio- what better than for example lamellicorn beetles (Scarabaeidoidea) and coenoses are insects
The which the urban cenoses are the specific environment for many species of comparative analysis of the fauna in different cities of Ukraine is available
Staphylinids are hard to describe regarding the hygrothermal preferendum, as the temperature and moisture in the litter and cracks in the soil and other substrates where Staphylinidae live significantly differ from such for above-ground conditions. Distinguishing these groups in relation to temperature and moisture is to some extent subjective and based on the analysis of general microclimatic conditions of one or the other stage, but taking into consideration the available literature data on the impact of these ecological factors on rove beetles (Tikhomirova, 1973; Kanao et al, 2016; Betz et al, 2018)
Summary
The most important representatives of natural and transformed bio- what better than for example lamellicorn beetles (Scarabaeidoidea) and coenoses are insects. By contrast to some other beetles (for example Staphylinidae in urban cenoses of three cities of Ukraine, with analysis of Carabidae), there are not many studies on staphylinids in urban landscapes peculiarities of their fauna, characterization of the ecological structure of of Europe; the data on them are poor even at faunistic level. Detailed studies of the species composition of staphylinids, their abundance in green zones were undertaken for a number of cities of Central Material and methods
