The results of research conducted over the past 30 years in the forest ecosystems of Zhytomyr Polissia, in the areas affected by radioactive contamination as a result of the Chornobyl accident. In the course of the research carried out at the Poliskyi Branch of the Ukrainian Research Institute of Forestry and Forest Melioration named after G. M. Vysotsky, methods of forest radioecology, botany, and forestry were used, and the results were processed using statistical analysis. The peculiarities of radioactive contamination of the most common herbaceous and dwarf-shrub plants in the stands of black alder in damp fairly fertile site types were studied. As indicators characterizing these features, we used 137Cs specific activity in the aboveground part of plants and the transfer factor of radionuclide to plant phytomass from the soil. It was found that the highest values of the transfer factor of 137Cs from the soil to the aerial part of the plant phytomass in 1999 are characteristic of ferns: for Dryopteris cristata (L.) A. Gray (276.9 m2∙kg-1∙10-3), Dryopteris carthusiana (Vill.) H. P. Fuchs (236.5 m2∙kg-1∙10-3), Thelypteris palustris Schott (171.2 m2∙kg-1∙10-3), and Athyrium filix-femina (L.) Roth (164.0 m2∙kg-1∙10-3). It was found that among the higher plants, the highest values of this indicator are for the Agrostis stolonifera L. (263.5 m2∙kg-1∙10-3), Galium uliginosum L. (155.8 m2∙kg-1∙10-3) and Maianthemum bifolium (L.) F. W. Schmidt (155.4 m2∙kg-1∙10-3). It was found out that the previously noted trends and interspecific differences in radionuclide accumulation persist after 22 years. It is shown, using the example of three plant species (Lysimachia vulgaris L., Galium uliginosum, and Maianthemum bifolium), that during the observation period (1991-2021) there is a gradual decrease in radioactive contamination of living ground cover plants and the intensity of 137Cs intake into them. This is explained by the decay of the radioactive element, its entry into various perennial components of forest ecosystems, some fixation in the soil, and, possibly, its removal beyond their borders. The established decrease in 137Cs specific activity in the aboveground part of plants is described by linear equations: for Lysimachia vulgaris – Am = –605.34a + 3745.6; R² = 0.98; Galium uliginosum – Am = –5107.5a + 30698; R² = 0.99; Maianthemum bifolium – Am = –4661.6 a + 28280; R² = 0.98. The identified peculiarities of radioactive contamination of various plant species, changes in 137Cs specific activity in them, and transfer factors of the radionuclide from the soil in stands of black alder in damp fairly fertile site types can be used in scientific works to predict possible changes in its redistribution within the ecosystem, as well as in the practice of harvesting medicinal plants in areas contaminated with radionuclides.

The paper presents the results of field research on the occurrence of Succisella inflexa in Kampinos National Park, conducted in 2004-2015. Its stations are characterized and its distribution is given. The populations were mainly concentrated in the eastern part of the park. Forty-five stations have been reported, two of them most likely historical. They were most often in open sedge and meadow, and less frequently in thin shrub and young forests. The population sizes ranged from single specimens to many thousands. [ABSTRACT FROM AUTHOR]

The paper lists 135 taxa and 12 main plant communities found in the Dolina Potoku Olszanickiego – Łąki Olszanickie ecological use area during field research done in 2018–2019. For each taxon, information about the occupied habitat, synanthropic status, number of localities and frequency of occurrence are given. Phytosociological groups of species were distinguished and analysed. In the ecological use area, Conium maculatum, an endangered species (VU) of the Małopolska Upland, was recorded. The occurrence of rush meadow Scirpetum sylvatici (typical and degradated patches), meadow thistle Cirsietum rivularis (various degradative forms) and rush vegetation Caricetum rostratae was found. The main threats to ecological use is degradation of communities and natural succession as a result of cessation of extensive use of meadows (mowing, grazing) and the expansion of the invasive species Solidago gigantea and S. canadensis, which occupy a significant part of the non-forest habitats. Information about needed protection measures is also given. The paper highlights the need for biodiversity protection in urban areas, for their sustainable development and the quality of life of their inhabitants. [ABSTRACT FROM AUTHOR]

The paper describes the distribution of Ophioglossum vulgatum in Poland, including localities recorded after 2000, and gives three new O. vulgatum sites in south-eastern Poland. Two of them are located in the Low Beskids in Bednarka and Żydowskie, and the third in the Zamojska Valley in Klemensów. [ABSTRACT FROM AUTHOR]

The forest environment is considered to be more resistant to penetration by alien plant species than other terrestrial environments, which generally are significantly modified by humans. A major environmental threat to vegetation is posed by alien species that are capable of spontaneous expansion in natural or semi-natural communities, and above all in forests. This paper presents a naturalization scale of alien vascular plants in forests of Poland, based on knowledge of species classified as naturalized elements of the Polish flora. Using the research results and observations of other authors, as well as literature data, a list of 180 taxa of such plants was compiled. The classification uses the following categories: life form, systematic affiliation, and origin or status in the Polish flora. The analysis revealed that not all of the considered alien species showed an ability to penetrate forest communities and that only a few of them have developed stable populations in the best-preserved natural and semi-natural phytocoenoses. About 20% of the anthropophytes found in forest communities strongly affect the composition and structure of the forest phytocoenoses. [ABSTRACT FROM AUTHOR]

The paper discusses semantic changes and stylistic derivation of the cultural concept of kołtun 'Polish plait' (Plica polonica) in Polish and Lithuanian. Although today it is impossible to meet a person with a kołtun on their head, the concept itself, as an element of socially established knowledge of the world, has survived and is still used in various discourses (ranging from dialectal texts and folklore, belles-lettres and journalistic writing, to contemporary Internet messages), to communicate different meanings, both literal and metaphorical. There are similarities and differences between the conceptualizations of kołtun in texts of Polish and Lithuanian cultures. The unifying element is the perception of kołtun as a formation of entangled hair or a mysterious disease that is inscribed into the folk system of beliefs and magical rituals. On the other hand, what sets the analysed concept apart in the two languages, is a much richer resource of folk and colloquial forms (compounds, hybrid words, phrasemes) in Lithuanian, and in addition, the lack of negative evaluation of kołtun in Lithuanian, whereas in Polish the word is often used to describe a backward, small-minded person.

In Górzno-Lidzbark Landscape Park (GLPK), 396 vascular plant species (~41% of GLPK's 965 vascular plant species) were recorded in 2002-2004 in a study of a ~4.5 km forested section along the railway track between Gutowo Pomorskie and Klonowo: 201 species in forest margins and scrubland, 256 species in firebreaks, 331 species on embankments, and 217 species on trackway. One species is under strict protection, nine under partial protection. Of the recorded species, Cimicifuga europaea, Epipactis atrorubens, Hierochloë australis and Melittis melisophyllum are disappearing from the GLPK forests. Six species are considered rare or endangered in Poland and eight are redlisted for the Kujawsko-Pomorskie region. We also recorded 30 archeophyte species, three ergasiophytes, and 16 confirmed or probable kenophytes. The recorded alien species do not pose a threat to the biodiversity of the GLPK forests. Several species (Hieracium cymosum, Lathyrus tuberosus, Neslia paniculata, Picris hieracioides, Reseda lutea, Vitis vinifera) have not been recorded elsewhere in GLPK. Our observations and those of other researchers indicate the potential importance of the railway in maintaining local biodiversity. [ABSTRACT FROM AUTHOR]

The paper describes a new locality of Primula matthioli L. from the Pilsko Group in the Beskid Żywiecki Mts. The species occurs in a stream valley where fragments of the Chaerophyllo- Cicerbitetum alpinae complex developed. The flora is dominated by tall-herb species of the Mulgedio-Aconitetea class and its lower syntaxa. The population of P. matthioli consists of ~200 individuals, most of which develop flowers and capsules. Species abundance and habitat inaccessibility suggest that the population is in very good condition. [ABSTRACT FROM AUTHOR]

The article is an aspect-oriented interpretation of Tadeusz Miciński's novel Nietota. Księga tajemna Tatr (Nietota: The Secret Book of the Tatra Mountains, 1910), with reflections focused on an analysis of the semiotic potential and construction function of the titular motif and those associated closely with nietota (rheumatism, Angelica archangelica, illness, cure, mystery), considered in the context of their symbolic meanings and inner-textual connections as well as against a wide cultural background, with particular emphasis on the presence of nietota (Huperzia selago, the northern firmoss - a medicinal and, simultaneously, highly poisonous plant) in the imaginarium of folk culture and its magical-medical practices. At the same time the article ponders the self-referential motif of the novel and - in a wider perspective - the inclination of modern literature towards formal experiences of this sort, linked with religious and metaphysical quests. For the author of Nietota such searches were tantamount to an encounter with mystery and, concurrently, became a form of initiation into "astonishing meaning", which appears in the world of people as "knowledge of darkness and pain". The article demonstrates that Miciński was convinced that this "'dark knowledge" comes from "touching a mystery" (and being touched by mystery) while one of its most essential symptoms is the subversive energy and healing power of art.

Microbryum davallianum (Sm.) R.H.Zander is a moss growing in the lowland of Poland. The number of its localities is estimated at over 70, the vast majority of them from the 19th century and the first half of the 20th century. Recently, Rusińska & Górski (2012) gave several stations of this species from the vicinity of Poznań, revising the available herbarium materials and presenting its occurrence in the country. It is unknown what factors are behind the rarity of M. davallianum in Poland. The current situation of this moss indicates that it should be considered an endangered species, mainly due to the significant decrease in the number of its stations. The paper describes a new station discovered on 27 June 2018 in Białobrzegi near Zamość in the Lublin Upland (50°45'24'N, 23°8'50'E, leg. R. Krawczyk, LBL, SOSN). The plant inhabited the periodically flooded and plowed margins of a mid-field depression, profusely producing sporophytes. [ABSTRACT FROM AUTHOR]

In April 2014, a new locality of Salix myrtilloides was found in the eastern part of Kampinos National Park in the abandoned village of Wyględy Górne (Leszno municipality, Warszawa Zachód District; GPS: 52°17′35.4″N, 20°41′41.5″E). The population consisted of 17 stems scattered in an area of 30 m2 within a poor fen that developed between small dunes. The main threat to the species at this locality is the poor quantity of these plants, which makes the population susceptible to sudden changes in environmental conditions. Another threat is biocenotic succession and the associated increase in shading from shrubs and perennials. [ABSTRACT FROM AUTHOR]
