Opis:
The aim of this work is to compare the species composition of phyllophagous Lepidoptera in deciduous trees of Kharkiv city as of the 1960s and 2017-2020, as well as the distribution of insect species by lifestyle, by the size of individuals, and by the ability to mass propagation. The greatest increase in the number of genera and species was noted in the families Gracillariidae, Tortricidae, and Geometridae, and a decrease in the families Notodontidae and Erebidae. Gracillariidae has been replenished due to 4 alien species: Cameraria ohridella, Macrosaccus robiniella, Parectopa robiniella, and Phyllonorycter issikii. Open-living species predominate in both assessments, however, at the second assessment, the number of species with semi-hidden and hidden lifestyles increased as well as the number of middle-size and small-size species. The eruptive species from the fi rst assessment became rarer, and alien species more often.

Opis:
To date, the issues of the Quercus rubra L. ecological niche formation, adaptation of its introduced populations, competition with populations of native trees in the secondary range forests remain open. Purpose: to conduct an inventory of the pine-oak forests ornithocomplex with the participation of the population of Q. rubra on the territory of the Boyarka Forestry Research Station (Ukraine), to give a comparative analysis of the pine-oak forests ornithocomplexes with Q. rubra and Q. robur as a result of the participation of the introduced species in the conditions transformation of birds habitats. It was revealed that because of the replacement of native Q. robur with adventive Q. rubra in pine-oak plantations, a significant decrease in the species composition (from 24 to 15 species) occurs in ornithocomplexes during the nesting period. The value of the Sorensen index for model ornithocomplexes is 0.62. The average number of birds in both cultural phytocenoses is similar: 2.59 ± 0.50 individuals/km of the account line in subors with Q. robur and 2.51 ± 0.57 individuals/km with Q. rubra. The replacement of Q. robur with Q. rubra does not significantly affect the value of the synanthropization index (0.46 with Q. robur and 0.47 with Q. rubra); does not adversely affect ground-nesting species (L. arborea, A. trivialis, T. troglodytes, Ph. trochilus, Ph. sibilatrix), indicating the presence of nesting stations for vulnerable species. Parus major L., Phylloscopus collybita Vieillot, Ph. sibilatrix species dominate in the forest without introduced trees; with Q. rubra – species Turdus pilaris L., P. major, Anthus trivialis L. predominate. Both types of pineoak plantations provide a full-fledged food resource for birds feeding on invertebrates and mixed feeds. The absence of predator birds, especially hawks, in the forest with Q. rubra is most likely due to the depletion of the food supply due to a smaller species composition and a smaller number of prey. As a result, predators visit subors with Q. rubra less often. The data of all species diversity indices are significantly higher for ornithocomplexes of model pine-oak forests with Q. robur. Dominance indexes data do not include synchrony (Simpson index data are stable, Berger–Parker index is higher in stands with Q. rubra, and McIntosh index – with Q. robur respectively). The data for the indices of species distribution uniformity are close.
