Oak forests of the alliance Scutellario altissimae–Quercion roboris Goncharenko et al. 2020 in the South of the European part of Russia

The article describes a new association of meso-xerophylous forests in the South of the European part of Russia Poo nemoralis–Quercetum roboris ass. nov. hoc loco, its differentiation from analogous syntaxa is discussed, and new data on the distribution of communities of the alliance Scutellario altissimae–Quercion roboris Goncharenko et al. 2020 on the Russian Plain are done. Vegetation classification was carried out by J. Braun-Blanquet approach based on 470 relevés of forest vegetation, collected by the author in 2007–2021 in the northern and central parts of Rostov, Voronezh and Volgograd Regions. In addition, the analysis included 777 relevés from the phytocenary made by G. M. Zozulin in the same regions in 1960–1980s. Based on the studies carried out, the current area of the alliance can be expanded to the lower reaches of the Don River. For a more adequate reflection of the floristic, ecological and geographical features of its communities, it was proposed to change the composition of the diagnostic species of the alliance and it was recommended to amend the current definition of the order Quercetalia pubescenti-petraeae, expanding its area to Eastern Europe.

Annotated checklist of the flora of Sverdlovsk Region. Part VII: Dicotyledonous plants (Asteraceae, Cichorioideae)

This article for the first time presents a detailed checklist of the flora of dicotyledonous plants (Asteraceae, Cichorioideae) of Sverdlovsk Region, based on the long-term filed research, a critical study of herbarium materials and literature sources.

The information on all the species is given on the occurrence in botanical-geographical districts and administrative districts of the region. In the checklist for species bioecological features are indicated (life form according to K. Raunkiaer and I. G. Serebryakov, coenotic groups and ecological groups in relation to moistning), zonal and longitudinal arealogic group, economic significance. As for the alien species, origin, migration thecnique, and level of naturalization achieved in the region are additionally indicated. Species that need protection in the region are noted.

Communities with Galega orientalis Lam. in Kursk Region

. Plant communities dominated by the invasive species Galega orientalis, common in natural and anthropogenic habitats, have been identified in Kursk Region. On anthropogenic ecotopes (wastelands, roadsides), phytocoenoses of the ass. Galigetum orientalis are formed as a result of introduction of Galega orientalis into communities of the order Agropyretalia intermedio–repentis (class Artemisietea vulgaris). In natural habitats, Galega orientalis spreads in mesophylous meadow communities (order Arrhenatheretalia, class Molinio-Arrhenatheretea), while derivative communities Galega orientalis [Arrhenatheretalia] are formed. Galega orientalis is unevenly present in derivative communities, forming separate loci, as a result, its cover is less intensive than in anthropogenic communities. It may be due to a more intensive distribution of this species in disturbed habitats. Comparison of ranges of values of environmental factors showed that derivative communities are formed in wetter habitats. Phytocoenoses of the association are characterized by wider variation in values of acidity and richness of soils in mineral nitrogen.

Diversity of lichen biota of oak forests of the reserve «Vydritsa» (Republic of Belarus, Gomel Region)

As a result of the research, the species composition of lichens and closely related fungi of the oak forest of the reserve «Vydritsa» (Republic of Belarus, Gomel Region) has been revealed. An annotated list, including 113 species has been compiled, 106 of these species are lichens, 6 – non-lichenised saprobic and 1 – lichenicolous fungi. Species Calicium adspersum, Cetrelia olivetorum, Chaenotheca chlorella, Cladonia caespiticia, Lobaria pulmonaria and Parmotrema stuppeum are included in the Red Data Book of Belarus and are listed for the first time for the Svetlogorsk district and the reserve «Vydritsa». The indicator lichens of old-growth oak forests include 20 species; 28 species were recorded in all 12 surveyed localities.

Records of rare species of vascular plants and lichens in the Bryansk Region in 2018–2021

In 2018–2021 the authors carried out floristic and geobotanical studies in the Bryansk Region according to the Program for maintaining the regional Red Data Book. In 2020 and 2021 this work was supported by the regional Department of Natural Resources and Ecology. As a result, the studies in the Bryansk Region and in the urban district of Bryansk discovered previously unknown locations of rare species of vascular plants and lichens, including those listed in the Red Data Book of the Region (Krasnaia..., 2016), and a list of species requiring additional observation and monitoring.

Epixylic component of bryoflora of the Polesye Region

The article gives a detailed description of the epixylic component of bryoflora of the Polesye Region on the terri-tory of Belarus, Russia and Ukraine. According to the results of a long-term comprehensive study of the Polesye bryocomponent, 468 species of bryophytes from three divisions have been recorded to date: Anthocerotophyta, Bryophyta, Marchantiophyta. On rotting and decaying wood, 159 species were identified, including 52 species belonging to the division Marchantiophyta, 107 – Bryophyta. The most representative in terms of species diver-sity are the family of liverworts Scapaniaceae, Cephaloziaceae, Calypogeaceae, Aneuraceae and Lophocoleace-ae, mosses – Brachytheciaceae, Amblystegiaceae, Dicranaceae, Hypnaceae and Mniaceae. The distribution of bryophyte species depending on the degree of decomposition of wood is shown, the forms of growth of bryophytes are considered, and hydromorphs are analyzed. An annotated list of bryoepixyls of the Polesye Region has been compiled. The systematic position, main synonyms, growing conditions, distribution in regions, ecological features, and occurrence are indicated for each species.

Typification and correction of forest vegetation syntaxa of the Western Caucasus

The article presents the typification and correction of mountain forests’ syntaxa established by one of the authors for the Western Caucasus. Unvalid classification units are validated according to the International Code of the Phytosociological Nomenclature (Theurillat et al., 2021): 2 associations of mesophytic deciduous forests of the order Lathyro–Carpinetalia and 3 associations of fir-beech forests of the order Rhododendro pontici–Fagetalia orientalis of the Carpino–Fagetea class, as well as 2 associations of oak pubescent forests and juniper woodland communities of the class Quercetea pubescentis. The main reasons of the invalidity of original publications are the absence of a nomenclature type or the ineffectiveness of the publication.

New higher syntaxa of the steppe vegetation in the North Caucasus

Geobotanical studies were carried out in the North Caucasus, in the Stavropol kray (Russia) on Beshtau, Byk, Verblyud, Dzhutsa, Dubrovka, Zolotoy Kurgan, Kokurtly, Lysaya, Mashuk, Yutsa magmatic mountains, Bor-gustan and Dzhinal ringes in 2017, 2019–2021. Syntaxonomic analysis carried out from the standpoint of J. Braun-Blanquet approach (1964) made it possible to establish 2 new associations (Allio albidi–Dictamnetum caucasici ass. nov. hoc loco, Helianthemo buschii–Elytrigietum stipifoliae ass. nov. hoc loco), 2 new alliances (Allio albidi–Dictamnion caucasici all. nov. hoc loco, Helianthemo buschii–Elytrigion stipifoliae all. nov.hoc loco) and 1 new order Galio biebersteinii–Bilacunarietalia microcarpae ordo nov. hoc loco. They are included in the class Festuco–Brometea Br.-Bl. et Tx. ex Soó 1947.
