As a result of studies of the genus Dactylorhiza undertaken by Alexey B. Shipunov, numerous "northern tetraploids" – plants combining the genomes of diploid D. fuchsii and tetraploid D. maculata s.str., were found among the material from North European Russia. However, it remained unclear whether non-hybrid D. fuchsii was represented in the northern part of the genus' range, as well as what the morphological distinctive features of plants with different ploidy levels were. Cariology and morphometric studies on material from the Murmansk Region showed that both diploid (2n=40) and tetraploid (2n=80) plants occur here, and plants with different ploidy, as a rule, do not occur together. Diploids were associated with D. fuchsii, but their high morphological similarity with tetraploids was noted, apparently due to the smoothing of morphological differences in "northern tetraploids", as well as due to the weak ecological divergence of species of the genus Dactylorhiza in the northern part of their range. The best distinguishing features of plants with different ploidy, established by methods of mathematical statistics, are considered in detail in the paper.
由于Alexey B. Shipunov对Dactylorhiza属的研究，许多“北方四倍体”植物组合了二倍体D. fuchsii和四倍体D. maculata s.str的基因组。是在来自俄罗斯北欧的材料中发现的。然而，在该属范围的北部是否有非杂交的富士草，以及不同倍性水平植株的形态特征是什么，目前还不清楚。对来自摩尔曼斯克地区的材料进行的生物学和形态计量学研究表明，这里既存在二倍体(2n=40)，也存在四倍体(2n=80)植株，而具有不同倍性的植株通常不会同时出现。二倍体与龙舌兰有亲缘关系，但与四倍体的形态相似性较高，这可能是由于“北部四倍体”的形态差异趋于平滑，以及其分布范围北部的Dactylorhiza属物种的生态分化较弱。本文详细讨论了用数理统计方法建立的不同倍性植物的最佳区分特征。

In the modern world, outer space is an object of research in various fields of scientific activity. One of these spheres is plant breeding, i.e. cultivation of higher plants, as they are the most promising from the side of use as photosynthetic organisms. The use of nutrient media in which agar-agar, basalt wool, microcellulose can be used as a thickener is considered for plant life support. Also, 1.5 ml of 2-ip hormone was added to all substrates to stimulate plant growth. It was found that using agar-agar as a nutrient thickener in an amount of 15 g/l, allows the best growth and development of plants obtained by microclonal propagation under microgravity conditions. In addition, mechanical tests of nutrient media with agar-agar as a thickener determined the resistance to external factors, because the resulting substrate does not yield to indentation, deformation and fluidity.

In this paper, we present nomenclatural novelties required in the course of the preparation of the second, revised version of the checklist of vascular plants of Asian Russia. The first version was published in 2012 (Baikov 2012). At the family level, we accepted the modern classification systems (APG IV for flowering plants, PPG I for lycophytes and ferns, and GPG for gymnosperms). At the genus level, we follow the generic concepts applied for particular taxonomic groups according to the Catalogue of Life (COL; https://www.catalogueoflife.org/), version COL23.5. At the species level, we consistently apply the monotypic species concept (also known in Russia as Komarov’s concept). In total, this paper presents one new nothogenus name (× Sibirotrisetokoeleria Chepinoga nom. nov., Poaceae) and 156 new names in the rank of species, in 28 families: Amaranthaceae Juss. (1 name), Amaryllidaceae J. St.-Hil. (1), Apiaceae Lindl. (2), Asteraceae Bercht. & J.Presl (12), Boraginaceae Juss. (4), Caryophyllaceae Juss. (11), Crassulaceae J. St.-Hill. (3), Cyperaceae Juss.

In order to reveal the structure of the monomerous diaspores of Pandanus, to clarify the position of the ovary and to determine its morphogenetic fruit type the fruits of P. austrosinensis and P. conglomeratus were studied. The fruiting carpel is differentiated into the proximal part (zone of the locule) and the distal part (pileus). In the proximal part, the exocarp is single-layered or lacking in case of carpel fusion, the mesocarp includes numerous scattered vascular bundles comprising 3 circles and is differentiated into peripheral (parenchymatous) and inner (sclerenchymatous) zones. The inner mesocarp and the single-layered sclerenchymatous endocarp comprise a stout stone. Since the structural type of the gynoecium and the nature of the female fructifications of Pandanus are currently undetermined their diaspores the studied species could be treated as monomerous drupes of Prunus type or as a fruiting carpel of polymerous pyrenarium of Butia type.

Diversity and structure of benthic diatom assemblages in 16 Crimean nearshore habitats with varying levels of technogenic bottom area pollution at depths range 0.5–50 m were investigated and accessed using Taxonomic Distinctness indices (TaxDI). In total 793 species and intraspecific taxa, belonging to 736 species, 130 genera, 53 families, 27 orders and 3 classes of Bacillariophyta were registered. The structure of diatom assemblages from polluted sites can be described as having low species richness and a large proportion of mono- and oligospecies branches at the family and order levels. In locations under a moderate anthropogenic impact, the structure was characterised by relatively high species richness and an equal ratio of oligo- and poly-species branches closed at genus level, with the presence of monospecies branches converging at family or order level. Taxocenes in pristine sites were distinguished by the highest species richness and a predominance of poly-species branches closed at different hierarchical levels.

New records of two rare moss species, Sphagnum inexspectatum Flatberg (4) and S. mirum Flatberg & Thingsgaard (9) are reported from Western Siberia, and discuss them in context of their habitat preferences in region as well as general range. Their distribution in Russia is considered and re-assessed. Geobotanical relevés of plant communities with Sphagnum inexspectatum and S. mirum from Western Siberia are presented. It is shown that in the taiga zone S. inexspectatum occurence is closely related to communities of the alliance Stygio-Caricion limosae Nordhagen 1943, class Scheuchzerio-Caricetea nigrae Tx. 1937, and similar Sphagnum carpets in meso-oligotrophic mires, where it grows as single stems among other peat mosses in poor conditions on slightly acidic substrates. In forest tundra and southern tundra this species occurs only in communities of the alliance Caricion stantis Matveyeva 1994. More diverse communities with S. mirum are assigned mainly to the alliance Sphagno-Caricion canescentis Passarge (1964) 1978, which comprises sedge-Sphagnum vegetation located in fens and transitional bogs in a wide variety of habitats from moderately poor to moderately rich in mineral nutrients and with slightly acidic substrate. This species occurs both with low (as single stems) and high abundance (frequently being dominant) in moss layer.

More diverse communities with S. mirum are assigned mainly to the alliance Sphagno-Caricion canescentis Passarge (1964) 1978, which comprises sedge-Sphagnum vegetation located in fens and transitional bogs in a wide variety of habitats from moderately poor to moderately rich in mineral nutrients and with slightly acidic substrate. This species occurs both with low (as single stems) and high abundance (frequently being dominant) in moss layer.","PeriodicalId":37724,"journal":{"name":"Botanica Pacifica","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67440034","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}
In this study, we report the somatic chromosome numbers (2n) of 31 taxa belonging to Asteraceae, Brassicaceae, Poaceae, Hypericaceae, Lamiaceae, Fabaceae and Plantaginaceae families from wetlands of Hamadan region in Iran. The chromosome numbers of about half of these species have not been reported in the previous literature. Chromosome number of Ononis spinosa counted chromosomally for the first time at the world level and the chromosome numbers of Erigeron acer, Pulicaria dysenterica, Arctium lappa, Xanthium strumarium, X. spinosum, Barbarea plantaginea, Brachypodium sylvaticum, Polypogon fugax, Prunella vulgaris and Lathyrus chloranthus, are here reported for the first time from Iran. In all taxa 2n was 12, 14, 16, 18, 20, 24, 28, 30, 32 and 42, as a diploid, tetraploid and hexaploid levels. These newly available data are further compared with those previously published for the same or related species.

Afroalpine plants develop under specific climate with great daily fluctuations and weak seasonal dynamics of temperature. Do leaf functional traits of the plants in Mt. Kenya differ from those of temperate plants in NW Caucasus? To answer this question, we conducted a comparative study at the Teleki valley (4000–4500 m a.s.l.), Mt. Kenya, Kenya, and Teberda national park (2600–2900 m a.s.l.), the Caucasus, Russia. We measured leaf area, fresh and dry mass, C, N, P, δ13C, δ15N and derivative traits (specific leaf area – SLA, leaf dry matter content – LDMC, C:N and N:P ratios) for 48 species at the Teleki valley, and the same traits, except for the δ13C and δ15N, for 141 species in the Teberda national park. The CSR-strategies scores were calculated. We applied the Principal Component Analysis to reveal the main patterns of trait variation. Leaf dry mass of Mt. Kenya alpine plants ranged from 0.27 mg (Sagina afroalpina) to 14.0 g (Dendrosenecio keniodendron). Leaf area, mass and LDMC of alpine plants in both regions did not differ significantly. The SLA of Mt. Kenya’s plants varied about 20-fold: from 2.6 mm2 mg-1 (Festuca pilgeri) to 39.8 mm2 mg-1 (Cineraria deltoidea), and Caucasian plants had higher SLA. N and P leaf concentrations were higher, but C lower in Caucasian plants than in Kenyan. Leaf N:P ratio was similar for both regions, while C:N ratio was higher in Kenyan plants. Species of “rosette” trees (Dendrosenecio spp.) differed from other species by size characteristics (maximal leaf dry mass and area were in Dendrosenecio keniodendron), as well as correspondingly higher investment to mechanical tissues (high C:N ratio, low SLA). By the other functional traits, “rosette” trees were similar to many other alpine plants. Thus, afroalpine plants of Mt. Kenya are close to temperate alpine plants by some leaf functional traits, but possess higher stress-tolerance.
