The influence of the climate humidity, mountain elevation and weather in the year of observations on the pollen morphology of the Siberian stone pine was studied. We compared the populations growing in the humid NorthEastern region of Altai (Mount Kolyushta, precipitation 867 mm/year, elevation 1350-1900 m) and the arid South-Eastern region of Altai (the Yuzhno-Chuysky ridge, precipitation 129 mm/year, elevation 1800-2100 m). It has been established that in an arid climate the body of a pollen grain is more spherical shape and larger in size, in a humid climate it is more ellipsoidal shape and smaller in size. It has been suggested that the tendency towards the formation of a spherical shape of the body of pollen grains is associated with the conditions of existence in an arid climate. Larger pollen grains were also formed in the lower mountain belts of both regions and in a year with warmer weather. Temperature has much less effect on the size of the air sacs, in contrast to the humidity of the region. In a humid climate, the sacs had an elongated shape, in an arid climate they were more rounded, but at the same time they did not differ significantly in volume. It is shown that the studied populations are more distant from each other in terms of the regional humidity factor, although the elevation and the weather also significantly influenced the pollen morphology of the Siberian stone pine.

Cephalanthera rubra (L.) Rich. is sporadically distributed in the Sochi Black Sea region. It occurs in the forests of the low-mountain and mid-mountain belts of the southern macroslope of the Main Caucasian Range. The number of individual populations is from two-three to a dozen individuals, usually populations are distant from each other over long distances. C. rubra can be attributed to hemiephemeroids, having spring-early summer green shoots with a period of summer-autumn-winter dormancy. The growing season lasts 3 months. Morphometric indicators of individuals of different ontogenetic states are given. The dynamics of the ontogenetic structure of the population from the area of the hornbeam forest in the vicinity of the village Illarionovka for 8 years is shown. In the ontogenetic spectra of the studied large population, the predominance of generative individuals is constant. The population is full-membered, normal type, stable. The species is self-compatible, autogamy was not revealed. The model species for pollinators seems to be Lathyrus laxiflorus (Desf.) Kuntze, which is absent from the studied population. Fruit formation in different locations does not always occur; it is absent in the studied population. Seeds of Limodorum-type, linear or fusiform, about 1.3 mm long. The species is protected in the Sochi National Park and in the Khosta Department of the Caucasian State Natural Biosphere Reserve.

The main topic of this scientific work is the study of the characteristics of species ribotypes under conditions of long-term ecological and reproductive isolation. Three groups of endemics were selected. The first group is gypsophilic species: ^rydalis sangardanica Mikhailova, С. microphylla Mikhailova, С. gypsophyla Mikhailova. The second group is the rock cushion species: С. mira (Batalin) C. Y. Wu et H. Chuang, and С. yazgulemica Mikhailova et Sochivko. The third group is rocky, geographically isolated species: С. macrocalyx Litv, and С. rupestris Kotschy. The scientific novelty in this work is the use of genetic methods of analysis in the field of studying the possible hybridization of species of the genus Corydalis (Fumariaceae). NGS (Next-Generation Sequencing) was performed on the Illumina MiSeq platform. The first transcribed spacer (ITS1) of the nuclear ribosomal 35S rDNA gene was taken as a marker region. As a result, for each sample, a set of Zotu multicopy ribotypes (zero-radius operational taxonomic unit) was obtained, on the basis of which a qualitative and quantitative comparison of the samples was performed. It was shown that there are no common ribotypes in all three groups. The number of ribotypes in the studied species varies from one to six, which may be due to the peculiarities of hybridization in the past.

Studies of epiphytic cyanobacterial-algal cenoses along the highways of Ufa were carried out on five species of woody plants: deciduous (Betula verrucosa Ehrh., Populus nigra L., Tilia cordata Mill., Sorbus aucuparia L.) and coniferous (Picea obovata Ledeb.). A large species diversity of algoepiphytes from 5 divisions, 7 classes, 12 orders, 30 families, 48 genera and 85 species and intraspecific taxa was revealed. Epiphytes of the divisions Chlorophyta and Cyanobacteria dominated (41 and 38 species and intraspecific taxa, respectively), leading families - Oscillatoriaceae and Chlorococcaceae, genera - Phormidium, Leptolyngbya, Nostoc, Chlorococcum.The ecological analysis made it possible to identify six morphotypes. The predominance of colonial-coccoid algae was shown, which made up 31 taxa (36.5 % of the total). Trichal forms take the second place - 26 species (30.6 %), coccoid immobile - 22 species (25.9 %). The spectrum of ecobiomorphs of epiphytic cyanoprokaryotes and algae included 11 life forms: Ch32P16C11CF6aer6H4X4PF3hydr1B1аmph1. Oligoatmophytes have the highest species representation -77 %, mesoatmophytes - 17 %, the group of polyatmophytes is sharply depleted - 6 %. Comparison of the obtained results with the control in ecologically clean habitats showed no difference in the taxonomic and ecological composition of cyanobacterial-algal growths, the number of living cells.

The article presents the results of the introduction of woody plants into South Uzbekistan from North America. It is noted that 43 species of woody plants were tested from the Atlantic-North American region. In particular, 1 species were tested from the Appalachian province of this region. Thirty-eight species have been introduced from the province of the Atlantic Lowland, of which 26 are also found in the Appalachian province. The flora of the province of the Atlantic Lowland is much younger than the flora of the Appalachian Province and contains fewer relict and endemic taxa, which is explained by the geological youth of the lowland itself. From both provinces of this area, the vast majority of species are very promising and promising. From the Rocky Mountains, only 3 species have been tested. Although they are endemic to this province, under our conditions they have proved to be quite resilient. They belong to the hemixerophytes. Of the 3 provinces of the Madreana region, 9 species were tested, 6 of them were introduced from the California province. Most of the tested species of this area turned out to be resistant in the conditions of Southern Uzbekistan.

This study aims to study the processes of wilting of narrow-leaved (first year) seedlings and heart-leaved (second year) seedlings of relic plant Cardiocrinum cordatum after the flowering phase, as well as to study the factors affecting the number of Sakhalin (northern) population of Cardiocrinum cordatum, growing in the neighborhood of Yuzhno-Sakhalinsk. Yuzhno-Sakhalinsk and at the expositions of the Sakhalin branch of the Botanical Garden-Institute of the Far East Branch of the Russian Academy of Sciences (BSI FGBN FEB RAS). The scientific significance of this study lies in the establishment of approximate dates of the end of vegetation of singleleaved seedlings, i.e. determination of the start and end dates of wilting of seedlings of the first and second years of life of Cardiocrinum cordatum. Consequently, the values given in this scientific work will help to form new knowledge about the main features of vegetation of the relic plant, which directly affect the regulation of the number of Sakhalin populations of Cardiocrinum cordatum. As a result of the study, new data on the dynamics of wilting of plants of different age categories were obtained, as well as, an extremely rare phenomenon of fasciation was registered and described, which was not previously noted in scientific sources.

The relevance of the study is due to the fact that city tram tracks, embankments and right of way are specific ecotopes that are subject to significant anthropogenic disturbances and are places of synanthropic plants concentration. We have collected 59 species from 23 families and 49 genera of flowering plants. The family spectrum is dominated by representatives of Asteraceae, the leading family of regional flora. In the generic spectrum, most genera contain one or two species each, which indicates a sufficient floristic capacity of the technogenic ecotope of tram tracks. In terms of life form, perennial herbaceous plants with underground organs survive on the tram tracks, ensuring the constant renewal of plants. Approximately the same number of alien (or adventive) and local (or native) plants have been identified by origin. As expected, alien species are confined to ruderal habitats and are characterized by wide ranges (cosmopolitan, Eurasian-North American, Eurasian types). From local species on tram tracks, plants of open habitats (forest-meadow, meadow, forest edge and slope) find suitable ecological niches.

The article provides results of palynological and algological analysis of peat deposits from MIS-5c in the Kiryas site. Sampling and analysis were carried out from the same horizon that was analyzed by other methods in already published works with the dating of the underlying layer at 105.5 ± 3.6 thousand years ago. Algological analysis and spore-pollen analysis were carried out. Three successive changes in vegetation were identified in the territories adjacent to the studied section. Changes in the composition of algal communities were used to trace changes in watering and the trophic status of the peat bog. Peat formation began with warming in time after 105 thousand years ago, with forest-tundra vegetation; in the second stage, a biome close to the modern northern taiga was formed; in the third stage, cooling occurred with the formation of a forest-tundra community and the end of peat formation. Complex conjugate analysis of stratigraphic records by various methods increases the reliability of reconstructions of natural changes. The abundance of algae remains allows us to conclude that the water level and the trophic status of the peat bog have changed.

The abundance of algae remains allows us to conclude that the water level and the trophic status of the peat bog have changed.","PeriodicalId":508495,"journal":{"name":"Проблемы ботаники Южной Сибири и Монголии","volume":"44 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139364261","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
The ambiguity of the taxonomic position of Galium pseudorivale Tzvel. necessitated the identification of its status in the genus Galium. A comparative study of the morphological features of vegetative and generative organs of the species G. pseudorivale and representatives of the sections Trachygalium K. Schum. and Asperuloides Pobed. was carried out. For the first time, using a scanning electron microscope, the surface type of the sculpture of the pericarp of fruits of the species G. pseudorivale was established and described. It has been proven that G. pseudorivale is close to the species of the section Trachygalium, and not to the species of the section Asperuloides, where it was assigned earlier.
由于 Galium pseudorivale Tzvel.在分类学上的地位不明确，有必要确定其在 Galium 属中的地位。对 G. pseudorivale 和 Trachygalium K. Schum.和 Asperuloides Pobed.首次使用扫描电子显微镜确定并描述了假桔梗果皮雕刻的表面类型。事实证明，G. pseudorivale 接近于 Trachygalium 科的物种，而不是早先归属的 Asperuloides 科的物种。
