Species of the genus <em>Orobanche</em> (Orobanchaceae), parasitic on <em>Centaurea</em> in Central Europe, were previously considered to belong to the <em>O. elatior</em> group. At present, the taxon is differentiated into two species, <em>O. elatior</em> Sutton and <em>O. kochii</em> F.W. Schultz. The paper presents for the first time the distribution of <em>O. elatior</em> and <em>O. kochii</em> in Poland based on a critical revision of herbarium and the literature data, as well as the results of field studies conducted between 1999 and 2014. The majority of the species’ localities are in south Poland: Silesia-Cracow, Małopolska and the Lublin Uplands. The distribution of both species in Poland is mapped and chronologically organized, and is thus the most recent in Europe. The taxonomy, host preferences, and ecology are also discussed. Seeds of both species were also investigated using light and scanning electron microscopy, which resulted in the designation of diagnostic features. The new color form of <em>O. kochii</em> f. <em>citrina</em> is described and illustrated. An account of all revised herbarium specimens collected from Poland, deposited in Poland and neighboring countries, is presented.

Abstract The paper presents the current distribution of Orobanche alba subsp. major and subsp. alba in Poland, based on a critical revision of herbarium and literature data as well as results of my field studies. Most of their localities are in southeastern Poland: in the Małopolska Upland, Lublin Upland, Roztocze Hills, Polesie, Przemyśl Foothills (Pogórze Przemyskie), and Western Bieszczady Mts. These are the northernmost sites known for the species in Central Europe, so the new data extend its distribution range. Maps of distribution of both the subspecies in Poland and of subsp. major in Central Europe are included. Additionally, their seed micromorphology was compared using scanning electron microscopy (SEM). The taxonomy, biology, and ecology of both the subspecies of O. alba are also discussed.

For the first time both Light- and Scanning Electron Microscopy are aplied to re-assess diagnostic characters of type specimens for selected Stemonitales kept in the collections of the Natural History Museum London (BM). The results are used to revise published data and the type status is discussed for specimens of Amaurochaete comata G. Lister & Brândză, Comatricha longipila Nann.-Bremek., Comatricha lurida Lister, Comatricha pulchella (C. Bab.) Rostaf., Comatricha suksdorfii Ellis & Everh., Paradiacheopsis rigida (Brândză) Nann.-Bremek., Stemonaria irregularis (Rex) Nann.-Bremek., R. Sharma & Y. Yamam. and Stemonitopsis microspora (Lister) Nann.-Bremek at BM. A lectotype is proposed for Paradiacheopsis rigida (Brândză) Nann.-Bremek.

Abstract The paper presents the current distribution of Orobanche purpurea s. str. (excl. O. bohemica) in Poland, based on a critical revision of herbarium and literature data as well as results of my field research. Most of the records date back to the 19th or early 20th century and are now historical. Most of them lack also herbarium documentation. Since the 1950s the species has been found in 10 new localities, only partly documented by herbarium specimens. Currently it is present in only 4 localities, in valleys of the Lower Vistula and the Lower Oder (Odra) rivers and in the Silesian-Kraków Upland (Wyżyna alπsko-Krakowska). These are some of the northernmost sites known for the species, and the new data extend its continuous distribution range. A map of its distribution in Poland is included. The taxonomy, biology, and ecology of O.purpurea are also discussed.

Abstract The paper presents the current distribution of Orobanche alsatica in Poland, based on a critical revision of her­barium and literature data and on my field studies conducted in 2006-2011. The recorded localities are mainly in Polish Uplands: the Lublin Upland (Wyżyna Lubelska), Roztocze, and Polesie, less frequently in the Małopolska Upland (Wyżyna Małopolska) and Silesia-Kraków Upland (Wyżyna Śląsko-Krakowska). Distribution maps of O. alsatica and other species of the series Alsaticae (O. bartlingii and O. mayeri) in Poland are included. Their taxonomy, biology, ecology, and habitat pref­erences are also discussed.

AbstractCarbon nanotubes (CNT) are interesting candidates for the reinforcement in robust composites and for conducting fillers in polymers due to their fascinating electronic and mechanical properties. For the first time, we report the incorporation of multi walled carbon nanotubes (MWNTs) into silica-glass surfaces by means of partial surface-melting caused by a continuous wave Nd:YAG laser. MWNTs were detected being well incorporated in the silica-surface. The composites are characterized using scanning electron microscopy (SEM) and Raman-spectroscopy. A model for the composite-formation is proposed based on heatabsorption by MWNTs and a partial melting of the silica-surface.

The paper is devoted to ethno-cultural landscapes of the Republic of Tuva. Ethnocultural landscapes (ECLs) are specific socio-environmental systems that developed as a result of the interaction of ethnic groups with their natural and social environments and are in a constant process of transformation. An attempt is made to identify the mechanisms of the formation, functioning and dynamics of ethnocultural landscapes in the specific conditions of the intracontinental cross-border mountain region, as well as to establish the main factors-catalysts of their modern changes. For the first time an attempt is made to delimit and map the ethnocultural landscapes of Tuva. For this, literary sources, statistical data and thematic maps of different times are analyzed using geoinformation methods. The results of 2014-2018 field studies are also used, during which interviews with representatives of different ethno-territorial, gender, age and social groups were taken. It is revealed that the key factors of Tuva’s ethnocultural landscape genesis are the natural isolation of its territory; the features of its landscape structure; the role of government; population migrations from other regions and the cultural diffusion provoked by them. 13 ethnocultural landscapes are identified at the regional level. Their modern transformation is determined by the shift of climatic cycles, aridisation, globalisation of sociocultural processes, changes in economic specialisation and ethnopsychological stereotypes.

Currently, due to the intensive development of high-tech science-intensive medical and research devices, more and more attention is paid to the development of diagnostics of rare and difficult to diagnose diseases. It is known that among numerous nephropathies, hematuria may be the only symptom of kidney and urinary tract diseases, which complicates their diagnosis and treatment. In order to develop new approaches for the diagnosis of nephropathies, the authors have been studying the morphology of red blood cells in the blood and urine of children and adults using a scanning electron microscope for several years. The paper presents the results of studies of children with various kidney diseases, including IgA-nephropathy, and chronic glomerulonephritis. Scanning electron microscopy was used for the first time to detect nanoparticles on the surface of red blood cells, the size of which is comparable to the size of viruses, which became the basis for one of the authors ' assumptions, namely, the possible transport of certain types of viruses by red blood cells. Thus, some kidney diseases could be considered virus-associated. This paper presents for the first time the results of determining the glomerular filtration rate of both kidneys separately in the study of separate kidney function and of the study of urine smears obtained during catheterization of the ureters in patients with hydronephrosis of one of the kidneys by scanning electron microscopy. As in previous studies, nanoparticles were found on the surface of red blood cells, which leads to the conclusion about the possible viral nature of the disease of the considered patient. In addition, smear images obtained using a microscope showed a significant difference in the elements of the right and left kidneys urine, which did not contradict the data on the study of glomerular filtration rate. According to the authors, the capabilities of the scanning electron microscope can be applied in fundamental research of kidney diseases at the cellular and molecular levels, forming new ideas about their origin, as well as on the basis of which new methods of non-invasive diagnostics can be built.

We studied in detail a moss-lichen component of Shokalsky Island vegetation for the first time and identified 79 species of mosses and 54 species and 2 subspecies of lichens and lichenicolous fungi. All species of mosses and 23 species and 2 subspecies of lichens and lichenicolous fungi are recorded for the first time for the island. The study is based on collections made in South West part of the island, in arctic tundra. We also explored the participation of the mosses and lichens in the main types of plant communities and the species distribution in 10 ecotopes. The paper describes the noteworthy findings (Abrothallus parmeliarum, Aongstroemia longipes, Arthonia peltigerea, Caloplaca caesiorufella, Catillaria stereocaulorum, Ceratodon heterophyllus, Lecanora leptacinella, Sphagnum concinnum, S. olafii) and features of bryo- and lichenoflora of Shokalsky Island.
