Einkorn (Triticum monococcum L.) has a number of benefits attributed to the quality of its grain. Nevertheless, einkorn oil is little studied. Given a renewed interest in this crop, the purpose of the study was to investigate the lipid contents and fatty acid composition of oil from diploid wheat grain. Oil was extracted from dried whole wheat kernels by Soxhlet procedure. Fatty acid composition was determined by gas chromatography. The oil yield from the diploid wheat grain varied from 2.830.27% dry basis in Triticum monococcum var. sofianum Stranski to 4.460.49% in Triticum sinskayae A.Filat. et Kurk. Six major fatty acids were detected in all the wheat species under investigation. They are ranked in order of decreasing levels as follows: linoleic > oleic > palmitic > linolenic > stearic > palmitoleic. Ploidy doubling brought no significant alterations in fatty acid composition of T. monococcum grain. T. monococcum var. sofianum had the most beneficial unsaturated/saturated ratio (5.3) and the lowest the ratio of omega-6/omega-3 (9:1). Triticum boeoticum Boiss. (wild progenitor of einkorn) was inferior to domestic diploid wheat in terms of unsaturated fatty acid amounts, despite the very high total oil content (4.190.48%). As wheat oil is used in the cosmetics industry and given the surprisingly high oil yields from the diploid wheat grain, the collection accessions are worth considering through the lens of this trend in wheat products. However, none of the studied accessions can be recommended as breakthrough advantageous because of the ratios of omega-6/omega-3 of not lower than 9:1.

Located in the Iron Gates Natural Park, Romania, at the foot of the Locvei Mountains, the Sfanta Elena Karst Plateau is a very picturesque territory, characterized by a karst relief, covered by High Nature Value grasslands. In the last decade this territory has been subjected to increasing anthropogenic pressures, and specific concerns on biodiversity have been raised after the construction of a wind farm in 2011. Starting from a concern expressed by a scientist, our study aims to provide current data on plant species with conservation value and to assess the conservation status of orchid-rich grasslands around wind turbines after ten years of wind farm operation. During the operation period we identified 19 plant taxa with conservation value, eight of which which are orchid species. Four of them are new reports for this territory: Gymnadenia conopsea, Neotinea ustulata, Neottia nidus-avis and Orchis simia, as well other rare taxa such as Cirsium grecescui, Lathyrus sphaericus, Linum hologynum and Rumex thyrsiflorus, are mentioned for the first time. The orchid-rich grasslands in the wind farm area correspond to the Natura 2000 habitat 6210* whose structure and floristic composition are within the acceptable limits of Favourable conservation status. The conservation status of plant species is directly dependent on the quality of their habitat, as well as the variety of pressure and threat factors in the area.

The biodiversity conservation is based on our knowledge of the complete composition of plants and animals within a certain area. In this paper, we present data of biodiversity research in the Republic of Mordovia (European Russia). The obtained results are reflected in six vascular plant found for the first time in the studied region. Of them, four alien taxa (Philadelphus coronarius, Rosa x majorugosa, Spiraea japonica, Syringa josikaea) are known only in the Mordovia State Nature Reserve now. This underlines the need paying our attention to alien plants that escape into the wild (naturalize) in the least disturbed ecosystems of this Protected Area. The Urtica galeopsiifolia distribution needs to be clarified in more details because of its similarity to the widely known Urtica dioica. Thus, a majority of the species under discussion are alien plants considered as cultivated plants escaping in the wild. Taking into account the newly revealed species, the vascular plant flora of the Republic of Mordovia currently includes 1,472 species. In this study, we propose the continuing the study of man-made habitats in terms of accidentally or intentionally introduced alien species, as well as the searching of hidden taxa, such as Urtica galeopsiifolia found in this study.
生物多样性保护是建立在我们对某一区域内动植物的完整组成的认识的基础上的。本文介绍了摩尔多瓦共和国(俄罗斯欧洲部分)生物多样性研究的数据。研究结果反映在该地区首次发现的6种维管植物中。其中4个外来分类群(Philadelphus coronarius, Rosa x majorugosa, Spiraea japonica, Syringa josikaea)目前仅在莫尔多维亚国家级自然保护区发现。这强调了我们需要关注在该保护区受干扰最小的生态系统中逃到野外(归化)的外来植物。galeopsiifolia的分布需要更详细地澄清，因为它与广为人知的Urtica dioica相似。因此，所讨论的大多数物种都是外来植物，被认为是在野外逃逸的栽培植物。考虑到新发现的物种，摩尔多瓦共和国的维管植物区系目前包括1472种。在本研究中，我们建议继续对无意或有意引入的外来物种的人工生境进行研究，并寻找隐藏的分类群，如本研究中发现的荨麻。

Declines in endemic species have significant impact on global biodiversity loss. More efforts need to be harnessed to further protect endemic species from the current global extinction crisis. This study evaluated the current conservation status, factors responsible for risk of extinction and the trends in populations of Leucadendron, a plant genus endemic to the Cape region in South Africa. The SANBI (South African National Biodiversity Institute) Red List was employed in this study. The results revealed that over 50% of taxa in this genus are threatened and most of the species are exposed to habitat destruction and the presence of invasive species. It was also discovered that two species of this genus are currently extinct, which implies this genus is facing a high risk of extinction. More efforts, such as designing effective methods of controlling forces responsible for the risk of extinction of taxa in this genus, should be put in place to prevent their complete extirpation in future.

Knowledge of the overall syntaxonomic and habitat variability of forest communities with Arolla pine (Pinus cembra) within the Tatra Mountains (Western Carpathians) is still insufficient as field research was hindered by their hardly accessible localities and deforestation for high mountain grazing. Arolla pine woodlands were traditionally classified within the association Pino cembrae-Piceetum Myczkowski et Lesinski 1974, but recent surveys recognize more numerous units. Hitherto unpublished releves from the north-eastern part of the Tatra Mountains document the occurrence of several floristically and ecologically distinct Arolla pine communities: (1) acid woodland of Homogyno alpinae-Pinetum cembrae on nutrient-poor habitats over quartzitic bedrock, and (2) calcareous woodlands of species-poor Pyrolo rotundifoliae-Pinetum cembrae of sites with a well-developed, tangled humus soil horizon, Cystopterido montanae-Pinetum cembrae on habitats influenced by both limestones and quartzites, Primulo elatioris-Pinetum cembrae bound to sites with the most favourable humidity, and Seslerio tatrae-Pinetum cembrae with the most pronounced calcareous character.

Citrus plants, which are mostly cultivated in the southern tropical area of the country, are one of the important economic crops in Iran. Branch canker and dieback of citrus is an ongoing problem for citrus growers located in these areas and has imposed irreparable damage to the citrus production in this region in recent years. Disease symptoms consisted of the blight of vigorously growing shoots and dieback of the branches and rootstock trunks. This study aimed to characterize the citrus dieback pathogen morphologically and phylogenetically, and the species Neodidymelliopsis iranensis Soleimani & Goudarzi, sp. nov., is described and illustrated here. Isolates were derived from collected citrus samples with dieback symptoms. After preparing pure cultures from single spores on oatmeal agar and malt agar, the morphological features of the species were described and their pathogenicity was confirmed on lime (Citrus aurantifolia). Morphologically N. iranensis is easily separated from the other species of Neodidymelliopsis by the size of pycnidia, conidia septation, and NaOH test results. The morphological differences between our isolates and the other known species of Neodidymelliopsis were strongly supported by a multi-locus phylogenetic analysis based on the ITS region, and LSU, RPB2, and TUB2 genes. In the reconstructed phylogenetic tree, N. iranensis formed a well-supported clade with other Neodiddymelliopsis species in the Didymellaceae family, but was separated from all other Neodiddymelliopsis species. The distinct phylogenetic position is supported by differences in morphological features. Consequently, the specificity of the morphological and phylogenetical features of the collected isolates has convinced us to describe Neodidymelliopsis iranensis as a new species.

In densely populated European countries like the Netherlands, old landscape elements such as ancient woodlands and ancient hedges are today rare. Owing to the introduction of exotic species and indigenous trees and shrubs imported from other climate zones, recognition of truly wild, i.e. autochthonous, individuals and populations is now problematical, posing challenges for forest management agencies, particularly at Natura 2000 sites. The author has developed a method for recognising genetically pure wild woody species, based on characteristics of the plant itself and those of the growing site. With this method, explained here, around 70% of the Netherlands has been surveyed, along with much of Flanders and part of the lower Rhine region of Germany. The results are illustrated with reference to two Dutch ancient woodlands, where new insights were obtained in terms of native status of the woody species and the ‘authenticity’ of the tree and shrub layer.

The annual weed Bidens frondosa L. (Asteraceae) has been registered for the first time in the Kurgan Region in 2020 during research on the riverine vegetation of the southwestern part of Western Siberia. This invasive species was found in ten locations along the Iset River banks in the Kurgan Region. We have postulated that the Sverdlovsk Region serves as a source for the B. frondosa invasion into the Kurgan Region along the River Iset. Despite a single short-term field survey, B. frondosa was found in several sites. In the Kurgan Region, this invasive species is characterized by low population density in all plots. Since B. frondosa populations are characterized by much higher density in other regions of European Russia, an increase in the number of locations and density of populations is expected in the Kurgan Region in the future.

Aiming to a larger study of vegetation of the lower Some Plain (Romania), this short paper summarises the outcome of the floristic inventories performed in aquatic and marshy vegetation, which was dominant in the area until about three centuries ago when the extended wetland drainage has started. By using the phytosociological method, 20 plant associations assigned to four vegetation classes were distinguished. Without presenting phytosociological tables at this first stage, the syntaxonomical framework, distribution and species composition of the revealed plant communities are briefly discussed by reference to the process of wetland drying and successional change as well as to newly formed anthropogenic lakes. The conservative value of some plant community types is emphasized by mentioning the presence of several endangered species that are included in the European-level Habitats Directive and various regional or national red lists/books.
