Flora of the Troyeruchitsa State Reserve (Tver Oblast, Russia)

Pp. 4-17

Abstract. The flora of vascular plants of the Troyeruchitsa State Nature Reserve and three surrounding settlements was studied. In 2016–2019, I recorded 489 species of native and alien plants on an area of ​​10 km2 (supplemented with 12 species from papers published earlier), including 456 species growing within the reserve and 45 species along its borders. An annotated checklist of the flora is presented. All known locations are given for species known from 1, 2 or 3 localities. Three species (Erigeron ×huelsenii, Eupatorium purpureum, Rumex ×heterophyllus) are novelties to the flora of Tver Oblast. Six native species are new to the flora of Ostashkovsky District (Monotropa hypophegea, Plantago uliginosa, Rosa ×majorugosa, Rubus nessensis, Sparganium gramineum, Typha angustifolia) as well as 19 species of alien plants. Sixteen species from the Red Data Book of Tver Oblast and four species from the Red Data Book of the Russian Federation are reported from the reserve. A dataset of georeferenced photos uploaded on iNaturalist as part of the Troyeruchitsa Local Flora project (https://www.inaturalist.org/projects/lokalnaya-flora-troeruchitsa) encounts 434 observations of 358 species. High diversity of flora is the most important feature of the area.

List of vascular aquatic plants of the Yamalo-Nenets Autonomous Okrug

Pp. 18-37

Abstract. The list of 51 species of vascular aquatic plants, detailed to the level of separate administrative districts or locations, of which 49 grow on the territory of the Yamal-Nenets Autonomous Okrug confirmed by herbarium collections. In addition, hybrids, species that are known only from literature are listed, as well as those included in the flora of the region by mistake.

a new alien species for the flora of Russia

Pp. 45-49

Abstract. In 2009-2012, Hydrocleys nymphoides, a new alien species for the flora of Russia, were noted at the treatment facilities of Nizhny Novgorod. After the reconstruction of treatment facilities, the local population was disappeared.

Habit polyvariance in virginal and young reproductive individuals of Quercus robur L. (Fagaceae)

in phytocenoses of the Upper and Middle Oka river

Pp. 50-75

Abstract. From the perspective of the modular concept plasticity of crown architecture in virginal and young reproductive individuals of Quercus robur L. has been researched. The individuals grow in phytocenoses of the Upper and Middle Oka river. The plant communities are subdivided into three groups accordingly to their light level (% of the full light): mesophytic meadows (100%), grass birch stands and pineries with small gaps (35–55%), closed canopy pineries (15–30%). The total amount of individuals is 210. For each individual shape, growth habit and ramification of axes of the main structural units of crown. Meanings of quantitative parameters of shoot systems were selectively measured. Four architectural types have been distinguished: “Мeadow”, “Мargin”, “Forest 1”, “Forest 2”. The individuals of the meadow and margin types grow within the 1st and 2nd light level group communities respectively. The individuals of the forest types grow within the 3rd light level group community. In a series from the meadow type to the forest types ramification of biennial shoot systems simplifies while shape and structure of the branches from the trunk and trunk itself get more complex. Thus we figured out that Q. robur has a significant polyvariance of shoot systems, which leads to formation of qualitatively different habit types.

Ecology of Stratiotes aloides L. (Hydrocharitaceae) communities

within the territory of European Russia

Pp. 80-92

Abstract. Stratiotes aloides L. is a common species in European Russia. It plays an important role in the functioning of fresh, mesoeutrophic, low-flowing water bodies with silty-clay and organic bottom deposits. It was found that in European Russia S. aloides forms at least 24 associations related to 12 formations of freshwater macrophytic vegetation. At least 119 species take part in the formation of these associations. Phytocoenoses of associations Stratiotes aloides purum, Stratiotes aloides aquiherbosa, Stratiotes aloides + Lemna trisulca and Typha angustifolia – Stratiotes aloides are the most common.

Key words: Stratiotes aloides, Hydrocharitaceae, ecology of community, vegetation

Hemileccinum impolitum (Fr.) Šutara (Boletaceae)

is a candidate for inclusion in the Red Book of Belgorod Region

Pp. 119-127

Abstract. The article presents the results of studying the state of the regional population of Hemileccinum impolitum (Fr.) Šutara (=Boletus impolitus Fr.) on the territory of Belgorod Region of the Russian Federation. 3 habitats of this species have been identified in the region. It has been established that the threatening factors for H. impolitum in Belgorod Region are: the point of populations, the critical distances between the nearest populations, the recreational load, and the collection of fruit bodies by the population. The following set of measures to maintain this species in nature is recommended: preservation of existing habitats and search for new ones in characteristic ecotopes; taking identified habitats under territorial protection; monitoring the number of known habitats at least once every 2-3 years; environmental education of the population.

Key words: Hemileccinum impolitum (=Boletus impolitus), fruit body, Red Book, status of species, location, habitat, population
