THE CONSORTIAL RELATIONS OF EURASIAN BLACKCAP (SYLVIA ATRICAPILLA L.) IN THE FOREST CENOSES OF LEFT BANK UKRAINE

Abstract

The consortium of the eurasian blackcap which forms a complex network of intercommunications that delivers survival and development of determinants and their consortium at the time is considered. It is established that representatives about of 30 higher taxons of animals and plants have trophic, topical, fabric and transportation service links with eurasian blackcap, as consortia determinants. At the same time, eurasian blackcap is the consort of autotrophic-determinantal consortia, whose cores  are 14 plant species (N = 165), where the predominant Acer platanoides L. (39.4 %). The fabric links of Eurasian blackcap eurasian blackcap with consortia of cereals (Poaceae) – 60 % (N = 35) and motley grass are detected. The eurasian blackcap belongs to the first concentre of many heterotrophic-determinantal consortia of mammals, birds and invertebrates. The nidikoly of eurasian blackcap are presented by invertebrates of 17 taxons (N = 348). Saprophages are dominated on all areas. Their share increasing from 55 % (N = 93) in the Hetmanskyi National Natural Park and 59 % (N = 174) in the National Natural Park “Homilshanski lisy” to 60 % (N = 81) in the forest park (Kharkiv). The eurasian blackcap is created the conditions for the development of other organisms as determinant of heterotrophic consortia. Micromys minutus Pall. is inhabited their nests (3.6 %; N = 165). The destroyed laying or dead nestlings are the trophic base for flies Calliphoridae, Sarcophagidae, Muscidae, beetles that feed dead bodies Silphidae, troksiv (Trox scaber L.), beetles-pistryanok (Necrobia violacea L.), coprophages Aphodius sp., Syritta pipiens L. and beetles, which feed the skin (Dermestes, Anthrenus), butterflies-keratophages (Tineidae). The trophic links of eurasian blackcap with 22 ta­xons (N = 576) of invertebrates was found. Phytophages are dominated on the two reserved areas by species composition. Zoophages (47.4 %; N = 135) are dominated in the forest park. The greatest similarity of species diversity of food objects was found for areas National Natural Park “Homilshanski lisy” and Hetmanskyi National Natural Park by 18 species of invertebrates (Jaccard index and Serens: 0.8 and 0.9, respectively).
