Opis:
Purpose: To develop a new concept of laboratory support for learners at different levels of education to maintain a high education quality in conditions of limited opportunities, such as lockdown, lack of funding, etc. Design/methodology/approach: To create a new concept, the practical experience of school teachers, educators of technical colleges and universities, research workers, as well as experience of scientists in the educational field published in open information' sources was taken into account. The development of a new concept was carried out from 2014 to 2016, and its implementation, introduction into the educational process, and possible ways to solve technical and organizational difficulties from 2016 to the present. In the last year, special attention was paid to distance learning. Findings: The development and the first practical steps to implement the new concept of updating the laboratory support of educational institutions clearly demonstrate of its practical implementation' feasibility. Positive consequences from the implementation were identified as constant improvement of laboratory equipment, increase in the educators’ level, transformation of virtual distance learning based on lectures and videos into real learning with "live" visual demonstration of physical, chemical, biological and other processes and experimental research. As a recommendation, should wish that at the state level to recommend the implementation of this approach and to propose some legal mechanisms to overcome identified problems. Research limitations/implications: The present study was conducted for Ukrainian educational institutions with the involvement of foreign students from different countries studying in Ukraine. Practical implications: The introduction of a new concept into the educational process in countries with a weak economy will improve the educational quality and reduce the cost of creating laboratory support. Originality/value: Equipment should not only be a teaching tool, but also a teaching subject.

Opis:
Montia linearis is a vascular plant originating from western North America. The expansion of this species has been observed for several decades. For the first time M. linearis was found in Europe in 1989. Further six populations were documented by 2004 within the continent: three in Poland, two in Denmark and one in Hungary. Apart from discovering a new population of M. linearis, we confirmed two out of the three previously known localities of the species in Poland. All the currently known populations of M. linearis occupied predominantly meadow habitats, especially intensively managed sites. Some individuals were also found in disturbed sites with bare soil. The studied species inhabited soils of various types with broad range of fertility as well as humidity. Montia linearis populations reached densities up to 87 individuals per 0.04 m2. The number of seeds produced by an individual was between 10 and 55 in 90% of the studied specimens, however much more fertile specimens were also observed. As the previously presented hypothesis of M. linearis dispersal with rail transport seemed not to be well supported, the connection between the M. linearis presence and cattle husbandry is considered. It is possible that the species can be transferred with living animals or manure. The species was able to survive for at least 26 years within once inhabited site. Further spread of M. linearis within Europe is highly probable. The aim of the study is to: (i) describe the current state of populations of M. linearis in Poland, (ii) provide information on habitat preferences and biology of the species, (iii) assess the invasiveness potential of M. linearis in Poland.

Opis:
This experimental study provides important data filling the gap in our knowledge on monazite stability under conditions of fluid-mediated low-temperature metamorphic alteration and post-magmatic hydrothermal alterations. The stability of monazite and maintenance of original Th-U-total Pb ages were tested experimentally under P-T conditions of 250–350 °C and 200–400 MPa over 20–40 days. The starting materials included the Burnet monazite + K-feldspar ± albite ± labradorite + muscovite + biotite + SiO2 + CaF2 and 2M Ca(OH)2 or Na2Si2O5 + H2O fluid. In the runs with 2M Ca(OH)2, monazite was unaltered. REE-enriched apatite formed at 350 °C and 400 MPa. The presence of the Na2Si2O5 + H2O fluid promoted the strong alteration of monazite, the formation of secondary REE-enriched apatite to fluorcalciobritholite, and the formation of REE-rich steacyite. Monazite alteration included the newly developed porosity, patchy zoning, and partial replacement by REE-rich steacyite. The unaltered domains of monazite maintained the composition of the Burnet monazite and its age of (or close to) ca. 1072 Ma, while the altered domains showed random dates in the intervals of 375–771 Ma (250 °C, 200 MPa run), 82–253 Ma (350 °C, 200 MPa), and 95–635 Ma (350 °C, 400 MPa). The compositional alteration and disturbance of the Th-U-Pb system resulted from fluid-mediated coupled dissolution-reprecipitation. In nature, such age disturbance in monazite can be attributed to post-magmatic alteration in granitic rocks or to metasomatic alteration during metamorphism. Recognition of potentially altered domains (dark patches in high-contrast BSE-imaging, developed porosity or inclusions of secondary minerals) is crucial to the application of Th-U-Pb geochronology.

Opis:
Thermodynamic modelling and monazite Th-U-total Pb dating via electron microprobe were used to improve the pressure, temperature and timing constraints of the HP-HT metamorphic record in granulites from Stary Gierałtów (NE Orlica-Śnieżnik Dome (OSD), SW Poland). The thermodynamic calculations constrained the P-T conditions to 20-22 kbar and ca. 920ºC in the felsic to intermediate granulites and 20-22 kbar and ca. 970ºC in the mafic granulite. These conditions are considered to closely represent the peak temperatures experienced by these rocks. In the intermediate granulite, the matrix monazite and monazite inclusions in garnet and allanite yielded an age of 349±2.5 Ma. An HP-HT metamorphic event with temperature conditions exceeding 900ºC, which are greater than the closure temperatures of most geochronometers, must have disturbed and completely reset the isotopic systems, including the Th-U-Pb system in the monazite. Consequently, this resetting prevented us from constraining the age of potential earlier metamorphic events or the igneous protolith. The 349±2.5 Ma age reflects the timing of the late-stage HP-HT event and cooling below 900ºC related to the initial exhumation of the granulites. A comparison of the new P-T-t constraints with previous data from the NE Orlica-Śnieżnik Dome indicates that the activation of the channels that exhumed the HP rocks to mid-crustal depths most likely initiated at ca. 350 Ma, and all the metamorphic rocks in the OSD likely shared a common Variscan evolution after ca. 340 Ma.

Opis:
Understanding human influence on vegetation dynamics is important from both conservation and human management perspectives. The Wieliszewskie Łęgi Reserve, located in central Poland, is a young forest area that was cut off from the flood waters of the Narew river in 1963, but since then has been constantly and intensively supplied with water from overflows under the dike. On the southern side, adjacent to the reserve, there are patches of valuable meadows, rushes and scrub communities. The aim of this study was to determine the degree of synanthropization of the flora in the Wieliszewskie Łęgi reserve and to assess changes occurring in its vegetation. The vascular plant flora of the reserve and its southern vicinity was surveyed in 2017 and the plant communities within the study area were mapped. In the area of the reserve, we observed a total of 264 vascular plant species, whereas for the entire area under study, 314 spe- cies were recorded. Of these, 14 were classified as valuable. The high species richness was mainly due to the presence of a large number of apophytes – native species quickly colonizing sites transformed by man. Therefore the degree of naturalness of the reserve's flora was relatively low, which is most likely due to the lack of refugia for typical forest species. A number of plant communities of non-forest, scrub and forest character, typical for swampy, wet, semixeric as well as dry habitats were recorded. Succession, manifested by the disappearance of non-forest and scrub communities and progression of forest communities, is superimposed on the processes of transformation into semixeric oak-hornbeam communities in the highest areas and carr com- munities in the lowest areas. A low proportion of kenophytes (16 species) and a zero value of the index of fluctuation changes indicate a relative resistance of the reserve to invasion by alien species.

Opis:
During the survey of Łempis Nature Reserve (Augustów Forest, NE Poland) 353 species of vascular plants were recorded, including 32 considered threatened with extinction in Poland (7 species from the Polish “red data book” and 32 species from the Polish “red list”). Among them there were 41 species protected under the Polish law, including 19 strictly protected species and four species listed in the Annex II of the EU Habitats Directive. Ten orchid species were recorded, including the most valuable plants of the nature reserve – Cypripedium calceolus, Hammarbya paludosa, Liparis loeselii and Listera cordata. Among 32 noted Cyperaceae species (including 26 members of the Carex genus), there was a number of threatened plants, e.g. Baeothryon alpinum, Carex chordorrhiza, C. loliacea and Eriophorum gracile. Other rare species included Agrimonia pilosa, Cladium mariscus, Laserpitium latifolium, Linnaea borealis, Potamogeton gramineus and Pulsatilla patens. The presence of anthropophytes was significant (4.5% of the flora), probably due to the past forest management practices as well as proximity of settlements. The extremely rich flora, along with pristine wetland ecosystems (mesotrophic lakes, various mire forests and fens), places the Łempis Nature Reserve among the most valuable nature reserves in Poland.

Opis:
During the survey of the Mały Borek nature reserve (Augustów Forest, NE Poland) 236 species of vascular plants were recorded, including 10 plant species red-listed in Poland and 19 species protected under the Polish law. The most valuable species were sedges typical of the boreal coniferous forests: Carex vaginata, C. globularis and C. loliacea. The presence of neophytes was very limited (1,3% of the flora) in the area studied. The principal aim of the establishment of the reserve was the conservation of old-growth coniferous forests with long ecological continuity. Since the reserve studied consists mainly of old-growth coniferous forests, the number of species regarded as ancient forest indicators is lower (54 species) than in the well-preserved reserves with deciduous stands in north-east Poland, but still rather high. The most valuable, threatened species are bound to wetland forests that are presently disturbed due to drainage. Restoration of the former hydrological conditions is essential for the preservation of the vascular plants in the reserve.
