A taxonomic revision of the Trichia botrytis species complex based on the study of specimens from the LE and MYX fungaria was made. Six of 7 previously described species of the complex (except for T. subfusca) and 10 taxa new to science (9 species and 1 variety) were recognized. Each studied morphotype, including the previously known ones, is described in detail and illustrated with LM and SEM photographs. In addition, nrSSU, mtSSU, and EF1α genes sequences are given for all 16 morphotypes. The variability of different features (including fruiting body morphology and species ecology) is discussed thoroughly, as well as their taxonomic significance and applicability in practice. A set of features that are highly recommended to be used in subsequent descriptions of new Trichia species and closely related genera is proposed and some methodological recommendations for morphological analysis are given.

The paper presents the results of different ways of overcoming dormancy of seeds of Oxytropis chankaensis Jurtz., a rare endemic species of the Far East characterized by small isolated populations. The peculiarities of seed germination under the influence of various abiogenic factors were studied: concentrated sulfuric acid, stratification, seed hilum puncture and abrupt temperature difference. A protocol for introducing the species studied to culture in vitro in order to preserve this endemic has been developed. The assessment of seedling viability after exposure to each of the factors was carried out. It was shown that the most effective and fastest way of scarification is the use of concentrated sulfuric acid. Stimulation of seed germination by this factor leads to 100 % seed germination and obtaining more than 90 % of viable plants capable of microclonal multiplication.

New data on the distribution of Ditrichum divaricatum Mitt. are presented. This species was described from Japan and previously known also from South Korea and China; it is identified in collections from Russia (Transbaikalia, Suntar-Khayata Mt. Range in Yakutia, and the Kamchatka Peninsula) and from Alaska (USA). Most specimens from Russia were previously attributed to D. pallidum (Hedwig) Hampe but the revision of the herbarium collections in MW, MHA, and LE did not confirm the presence of the latter species in the country. A description and illustrations of D. divaricatum based on Russian specimens are provided as well as data on its ecology; in the north of the Pacific, the species is confined to volcanic substrates of acidic composition.

Many alpine communities of the Tibetan plateau experience both harsh climates and heavy grazing, and the adaptations to such environment are realized in plant functional traits and strategies. We tested, which leaf traits allow to dominate in the two wide-spread alpine communities of the Eastern Qinghai-Tibetan mountains, Kobresia alpine meadows and alpine fens, and do meadows and fens differ by community-weighted dominance-linked traits, strategy affinities, and functional diversity. Lower leaf dry matter content (LDMC) and higher specific leaf area (SLA) provides the species dominance in Kobresia alpine meadows, while size traits do not influence the dominance. Both LDMC and SLA have low functional evenness and divergence in the two communities. The prevail of stress-tolerators reflects the abiotic environment of alpine plants, but high affinities to ruderal strategy are possibly related to grazing.

A new class, Carici arctisibiricae–Hylocomietea alaskani class nov. is described for vegetation of the tundra zone on a circumpolar scale. This higher unit in the system of Braun-Blanquet floristic (= floristic-sociological) classification unites the zonal vegetation in the intermediate habitats with respect to the substrate moisture, pH and texture, the snow cover thickness and duration, the depth of seasonal frozen ground thawing, and the growing season length on the interfluves (upland surfaces) within the tundra zone (CAVM subzones B, C, D, E = arctic, typical and southern tundra subzones in Russian zonal subdivision). Communities of the class are distributed on plains north of the tree line on two continents (Eurasia and North America), as well as on the archipelagos (Spitsbergen, Novaya Zemlya, New Siberian Islands, the Canadian Arctic Archipelago) and the large and small islands (Kolguev, Dolgy, Vaygach, Bely, Bolshoy Begichev, Ayon, Wrangel, Greenland) in the Arctic Ocean. The class comprises 3 new orders and 6 alliances. The diagnoses of higher rank units are given. Difficulties in describing and classifying zonal communities due to the specificity of their species composition and horizontal and vertical structure are discussed. The criteria distinguishing the new class from the known ones in the Europe and Asia mountains, in which zonal tundra communities are being placed until now, are presented.
在环极尺度上，描述了冻土带植被的一个新纲——arctisibiricae-Hylocomietea alaska class 11 .。这是布劳恩-布兰凯植物区系(=植物区系-社会学)分类系统中的高级单位，它将中间生境的地带性植被结合在一起，包括基材湿度、pH值和质地、积雪厚度和持续时间、季节性冻土融化深度以及冻土带(高原表面)上的生长季节长度(CAVM分区B、C、D、E =俄罗斯分区中的北极、典型和南部冻土带分区)。这个类的群落分布在两大洲(欧亚大陆和北美)树木线以北的平原上，以及群岛(斯匹次卑尔根岛、新地岛、新西伯利亚群岛、加拿大北极群岛)和北冰洋的大小岛屿(科尔格耶夫岛、多尔吉岛、Vaygach岛、别利岛、Bolshoy Begichev岛、Ayon岛、弗兰格尔岛、格陵兰岛)上。类包括3个新命令和6个联盟。给出了高阶单元的诊断。讨论了地带性群落由于其物种组成和水平与垂直结构的特殊性而在描述和分类方面存在的困难。提出了区分新类与欧洲和亚洲山区已知类的标准，这些地区到目前为止都是地带性冻土带群落。

The constant demand for new biochemicals to advance human life necessitates the study of organisms from novel biotopes. The scientific community is paying more attention to endophytes, one of the inhabitants of novel biotopes, as they have already gained recognition for their production of numerous novel biochemicals and for their enormous potential to contribute to the development of effective solutions to the world's most pressing problems. The aim of the current study is to discover, compare, and isolate the endophytic community of Ficus exasperata Vahl. and Ficus drupacea Thunb. The presence of endophytes was discovered in the leaves and fruits of both plant species. A greater number of organisms were found in the leaves, while only a few were found in the fruits. All of the isolates were from the Ascomycota and Basidiomycota divisions. The majority of the isolates belonged to the Ascomycota division, with only a few belongings to the Basidiomycota division.

Maianthemum F.H. Wigg. is a genus of perennial plants inhabiting temperate and subtropical regions of Eurasia and North America. Maianthemum sensu stricto includes just a few species that have a wide geographic distribution, are morphologically close, and possess open flowers adapted for a wide range of flower visitors. The present study is aimed at investigating the pollination biology of Maianthemum s.s. A comparison of the pollination biology of these species growing in the same area allows us to clarify ecological differences between the species. Investigation of the pollination biology of the same species in different parts of its range allows for the specification of variation in range of pollinators due to the environmental conditions. We studied pollination of M. bifolium in two far-apart locations (Moscow Region and Primorye Territory); also, in parallel, we studied three species M. bifolium, M. dilatatum, and M. intermedium in the same location in Primorye Territory. Proterandry is typical of all Maianthemum ssp. populations studied here. The studied species have a wide range of flower visitors. All of them can contribute to pollination, but the most stable and effective pollinators of Maianthemum s.s. are bees (Anthophila) and hoverflies (Syrphidae). Geographical position of population is the most important factor defining the range of pollinators of Maianthemum bifolium. The range of pollinators is weakly specific to the three species of Maianthemum s.s.
菊花。是一个多年生植物属，生长在欧亚大陆和北美洲的温带和亚热带地区。狭义菊(Maianthemum sensu stricto)包括地理分布广泛、形态相近、开放花朵适合多种赏花者的少数种。本研究旨在探讨菊花传粉生物学的研究，通过对生长在同一地区的两种菊传粉生物学的比较，可以澄清两种菊传粉生物学的差异。对同一物种在其分布范围不同地区的传粉生物学进行调查，可以说明传粉媒介的分布范围因环境条件而发生的变化。我们在两个相距遥远的地区(莫斯科地区和滨海地区)研究了双歧杆菌的授粉;同时，我们在滨海边疆区同一地点研究了双歧分枝杆菌、扩张分枝杆菌和中间分枝杆菌3种。菊花是所有菊花的典型品种。这里研究了人口。所研究的物种有各种各样的花访客。它们都有传粉的作用，但最稳定有效的传粉者是蜜蜂和食蚜蝇。种群地理位置是决定两叶菊传粉者分布范围的最重要因素。传粉者的分布范围对三种菊的特异性较弱。

The subgenus Orithyia in the genus Tulipa is considered one of the least studied. It includes the most eastern species of tulips. Previously, three species of tulips from this subgenus, T. heteropetala, T. uniflora, and T. mongolica were reported for the territory of Southern Siberia. The morphological analysis showed that studied plants, from populations previously reported in Southern Siberia under the name T. heteropetala, are large individuals of T. uniflora. There was a high level of morphological differences between all populations of T. uniflora and T. mongolica. Karyotype analysis showed that T. mongolica, T. uniflora, and T. siniangensis have similar karyotype structures. In T. heterophylla, in comparison with them, a lower level of intrachromosomal asymmetry was noted. Molecular genetic analysis confirms previous data and separates the subgenus Orithyia among other subgenera in the genus Tulipa. Molecular data confirmed taxonomic affiliation of specimens from the Zabaykalsky Territory (Russia) previously assigned by morphological characters to T. mongolica. Thus, it was confirmed that two species of tulips of the subgenus Orithyia, Tulipa uniflora and T. mongolica, grow in the studied area.
