Abstract The article presents new data on the distribution and acclimatization of an alien species of the American coniferous bug (Leptoglossus occidentalis Heidemann, 1910) from the European part of Russia. This bug was discovered in the autumn of 2019 on the territory of the city of Voronezh in the Arboretum of the Voronezh State University of Forestry and Technologies. Currently, L. occidentalis spreads on the territory of Russia only in an urban environment, where it finds optimal environmental conditions (suitable temperature, humidity and shelter for winter locations). Surveys of a number of park and forest park zones, squares and separately growing coniferous trees conducted in 2019-2020 in Voronezh did not reveal the presence of this species. At the moment, in the conditions of the Voronezh region, the center of the spread of this bug is located only in the Arboretum of the Voronezh State University of Forestry and Technologies. In 2020, an increase in the number of the identified group of L. occidentalis was recorded. Further spread of the bug is predicted on the territory of Voronezh. At the moment, no danger to conifers in the European part of Russia from L. occidentalis has been identified and is not yet expected, but constant monitoring of the detected group is required.

The Dunkleosteidae Stensiö family includes large predatory Paleozoic armour fishes. Their remains are rare in the Devonian deposits of the European part of Russia (Central Devonian field). The finds of both Eastmanosteus Obruchev and Dunkleosteus Lehman genus representatives and indefinte dunkleosteids were detected in the area. currently there is a collection of some dunkleosteid remains at the Earth Sciences Museum of Moscow State University. The materials were collected in two localities in 2007-2008 years by the author. Plates of the head and trunk shields, preliminarily determined as Eastmanosteus aff. E. pustulosus (Eastman), were found in the sandy clay deposits of the Ardatovka Horizon (Givetian, Middle Devonian) in the Pavlovsk Quarry, Voronezh Region. An incomplete anterior ventro-lateral plate of Dunkleosteidae gen. et sp. indet., similar to the same plates of the Dunkleosteus-species, was discovered in the sandy deposits of the Zadonsk Horizon (Lower Famennian, Upper Devonian) in the Lime Factory Quarry not far from Livny Town, Orel Region. The brief description of the new findings supplementing the data on the Middle-Late Devonian dunkleosteids of the Central Devonian field is given.

The paper provides the results of seven-year study of downy mildew on Skadovsky Zvenigorod Biological Station of Moscow State University (ZBS MSU, Moscow Region). A total of 29 species of Peronosporales (Oomycota) were revealed during the study. An annotated list of species is presented, among them Peronospora anemones is recorded for the first time for Russia, P. chelidonii and P. stachydis are new for the European part of Russia, 8 species are new for the Moscow Region.

Factor Regression

For young oaks separate volumes table was developed. We using the starting materials obtained two-factor regression equation underlying the single table that allows determining the volume of English oak trunks with diameter at a height of 1.3 m from 1 to 200 cm in height from 2 to 45 m. The data of regression analysis indicate high accuracy of obtained model approaching to functional one. Constructed table is recommended for use in determining the volumes of English oak trunks in the Central Black Earth region of Russia, and possibly the European part of Russia.

The materials presented in the article supplement the information of “Flora of the middle zone of the European part of Russia” (Maevskiy, 2014) for the floras of Voronezh and Lipetsk Regions. The materials were collected in the period 2007–2020 on the protected areas of Usmansky Bor: in the Voronezhsky State Reserve, its protected zone and in the Federal Preserve “Voronezhsky”. The flora of the Lipetsk Region is supplemented by 9 species: Alchemilla argutiserrata, Aronia mitschurinii, Carex remota, C. tomentosa, Centaurea majorovii, Cotoneaster lucidus, Hieracium sylvularum, Scirpoides holoschoenus, Symphoricarpos albus. The data on 11 new taxa are given for the Voronezh Region flora: Cotoneaster lucidus, Crataegus ucrainica, Hieracium sylvularum, Nymphaea × marliacea, Phytolacca acinosa, Philadelphus latifolius, P. serotina, Spiraea chamaedryfolia, Thuja occidentalis, Veronica polita, Wolffia globosa. The article reports on new finds of Carex bohemica and Prunus cerasifera, species that were previously noted in the region, but not included in “Flora ...” (Maevskiy, 2014). Among the 20 marked species, 11 taxa are alien ornamental plants and fruit trees and shrubs noted outside of cultivation areas. Leaving the places of cultivation by alien plants and naturalization in natural communities is a modern problem of protected areas in the European part of Russia.

Additional lichenological research was made in two nature reserves of the Central Chernozem Region (south-eastern part of Central Russia). As a result, 14 lichen species new to the Voronezh Region were found and 6 species new to the Central Chernozem Region as a whole. Among them, 5 indicating species of old-growth and moderately disturbed forest communities were noted, as well as 2 species rare in Russia. Other recorded species are rare for the Central Chernozem Region.

The microdistrict principle of urban environment organization, developed in Soviet urban planning, formed a certain configuration of the placement of trade and services. However, the market transformations of the 1990s dramatically affected both the number of retail facilities and their location. The purpose of this research was to identify the effects of retail development for the functions and morphology of the microdistricts of Soviet construction. The work is based on empirical materials on St. Petersburg, where research was conducted based on the study of telephone books in the late 1980s, and field mapping of selected areas of the city. It was found that at the moment there was a rapprochement of the retail functions of the areas of mass housing construction and the historical center. The number and density of everyday demand objects in microdistricts increased many-fold, while goods and services of periodic demand came out on top in terms of the number of objects. Retail of episodic demand has ceased to obey the center-peripheral principle in placement. The Soviet principle of spatial monopoly was replaced by the principle of spatial competition, which significantly transformed the morphology of urban space.

A new locality of the taxon from the genus Potentilla, endemic to the flora of Russia and Kazakhstan, was discovered in Eastern Europe. Previously, P. × angarensis was recorded for the European part of Russia based on collections from Moscow Region and the Republic of Udmurtia. The paper reports the first record of this hybrid for the Oka-Don Lowland, which was found in the northeast of the Voronezh Region. The main morphological characters of the hybridogenic taxon, which distinguish it from closely related species, are listed. The general distribution of P. × angarensis is specified. An image of the herbarium specimen of the new record is presented.
