    The paper describes a very complex research problem of urban living conditions in Piotrków Trybunalski and factors affecting them in the context of consequences of the system transformation in Poland. The analysis employs objective indices describing living, housing, working and leisure/recreation conditions in Piotrków Trybunalski. The knowledge about the level of the local community need satisfaction has been gained as a result of a field measurement on a representative (random) sample of Piotrków Trybunalski inhabitants. The key element affecting the level of satisfaction among inhabitants with their own residential environment is in the light of the work results the building aesthetics and the availability of social services (especially primary healthcare facilities and public libraries).W artykule przedstawiono diagnozę warunków życia w Piotrkowie oraz czynników na nie oddziałujących w kontekście konsekwencji transformacji ustrojowej Polski w oparciu o dostępne materiały źródłowe, jak i własne badania. Decydujące oddziaływanie na poziom zadowolenia mieszkańców z własnego środowiska zamieszkania ma w świetle wyników pracy estetyka zabudowy. Szczególnie ważne jest dla nich ponadto rozmieszczenie w najbliższej okolicy obiektów usług społecznych: podstawowej opieki zdrowotnej oraz bibliotek

    Rice field weed communities occurring in central Nepal are presented in this study. The research was focussed on the classification of segetal plant communities occurring in paddy fi elds, which had been poorly investigated from a geobotanical standpoint. In all, 108 phytosociological relevés were sampled, using the Braun-Blanquet method. The analyses classified the vegetation into 9 communities, including 7 associations and one subassociation. Four new plant associations and one new subassociation were proposed: Elatinetum triandro-ambiguae, Mazo pumili-Lindernietum ciliatae, Mazo pumili-Lindernietum ciliatae caesulietosum axillaris, Rotaletum rotundifoliae and Ammanietum pygmeae. Due to species composition and habitat preferences all phytocoenoses were included into the Oryzetea sativae class and the Ludwigion hyssopifolio-octovalvis alliance. As in other rice field phytocoenoses, the main discrimination factors for the plots are depth of water, soil trophy and species richness. The altitudinal distribution also has a significant influence and separates the Rotaletum rotundifoliae and Elatinetum triandro-ambiguae associations. The study shows that anthropogenic rice fields can harbour relatively rich rush and water vegetation. More than 80 species were noted in the vegetation plots. Several of them are considered to be extremely rare and have been recorded on the world Red List

    "A Narcissist without a face"? : postcolonial countenances of Danil Kiš

    Get PDF
    Zarówno w czasach Jugosławii, jak i po jej rozpadzie kluczową kategorią dla odczytań twórczości Danila Kiša stała się kategoria zaangażowania. To ona, uzasadniając jego status ikony pisarstwa środkowoeuropejskiego, okazała się punktem odniesienia dla toczących się wokół postaci pisarza dyskusji, związanych z istnieniem w Serbii postmodernizmu. Historia ataków na Kiša dopełniona zostanie najnowszymi, postkolonialnymi, inicjowanymi także z pozycji „zaangażowania”, rewizjami oceny dorobku twórcy. Zaprezentowane sposoby „użycia” wizerunku i twórczości Kiša potwierdzają tezę Gayatri Chakravorty Spivak o tym, że etyczny cel badań postkolonialnych jest w zasadzie „doświadczaniem niemożliwego”.Both in the days of Yugoslavia as well as after its collapse commitment has become the key category for reading Danilo Kiš’s works. It is exactly the category of the ethical commitment that became the point of reference of, associated with existing in the Serbia of postmodernism, discussions about the writer. It is also the same category that established Kiš's status of one of the most noted writers of East Central Europe. The history of attacks on Kiš will be supplemented with newest postcolonial, initiated from the position of "commitment", reinterpretations of his achievements. The presented ways of use of the Kiš's image and his artistic work confirm the Gayatri Chakravorty Spivak's thesis that ethical purpose of postcolonial research is in fact “experiencing the impossible”

    Diversity and distribution of rush communities from the Phragmito-Magno-Caricetea class in Pamir Alai Mountains (Middle Asia : Tajikistan)

    The study presents results of geobotanical investigations conducted in rush vegetation from the Phragmito-MagnoCaricetea class in the central Pamir-Alai Mts (Tajikistan, Middle Asia). Studies were carried out mainly within the SyrDaria, Pyandzh, Zeravshan, Kafirnighan, Khanaka and Surkhandaria river valleys in the years 2008‒2012. The research was focused on the classification of rush plant communities developing within this poorly-investigated area. Habitat conditions were checked for all vegetation plots, including pH reaction, water depth, inclination and altitude. Altogether 231 phytosociological relevés using the Braun-Blanquet method were sampled. The analyses classified the vegetation into 28 plant communities, including 26 associations. Eight new plant associations were proposed: Scirpetum hippolytii, Mentho asiaticae-Nasturtietum microphyllae, Juncetum brachytepali, Sparganietum stoloniferi, Eleocharitetum argyrolepis, Eleocharitetum mitracarpae, Caricetum songoricae and Rorippo palustris-Alismatetum graminei. The main discrimination factor for the data set is the floristic structure of the associations. Rush vegetation from the PhragmitoMagno-Caricetea class is spread throughout all river valleys of the research areas in montane and subalpine as well as in alpine zones. The vegetation patches occur mainly along the shores of water bodies and in ditches. Only sporadically have rush communities been noted within rice fields, where communities of the class Oryzetea sativae prevail. The study shows that riverside habitats with rush vegetation can harbour a relatively rich flora. Almost 200 species were found in vegetation plots, including some which are rare and have not been recorded until now in this part of Middle Asia

    Dwarf shrub vegetation of rock ledges and clefts in the Pamir Alai Mountains (Middle Asia: Tajikistan)

    Get PDF
    The paper presents the results of phytosociological researches on rocky slope vegetation in Tajikistan with the aim to establish a comprehensive syntaxonomical classifi cation system. Field studies were conducted in 2010–2014 in Pamir Alai ranges and Pamirian plateau. Nearly 500 relevés documenting rock and scree vegetation were made according to the Braun-Blanquet method. Numerical analyses of selected 58 relevés representing dwarf shrub vegetation on rock ledges made it possible to distinguish: Ephedro glaucae- Spiraeion baldschuanicae and Ephedrion regeliano-fedtschenkoi alliances, as well as Spiraeetum baldschuanicae, Rhamnetum coriaceae, Pentaphylloidetum parvifoliae and Pentaphylloidetum dryadanthoidis associations, community of Ephedra glauca and community of Rhamnus minuta. The classification of vegetation of dwarf shrubs on rock walls occurring in the Pamir Alai Mts is proposed. Because of the species composition, physiognomy and microhabitat conditions, the plant communities were included into Artemisio santolinifoliae- Berberidetea sibiricae class Ermakov et al. 2006. The main factors determining the species composition of the classifi ed associations seem to be the elevation above sea level.The newly described syntaxa are largely defined by species restricted to very narrow ranges in Middle Asi

    Aims: To complete the syntaxonomic scheme for tall-forb vegetation of the montane and alpine belts in the Pamir-Alai and western Tian Shan Mountains in Tajikistan and Kyrgyzstan with some remarks on its environmental predictors. Study area: Middle Asia: Tajikistan and Kyrgyzstan. Methods: A total of 244 relevés were sampled in 2013–2019 using the seven-degree cover-abundance scale of the Braun-Blanquet approach. These were classified with a modified TWINSPAN algorithm with pseudospecies cut-levels 0%, 5% and 25%, and total inertia as a measure of cluster heterogeneity. Diagnostic species were identified using the phi coefficient as a fidelity measure. NMDS was used to explore the relationships between the distinguished groups. Results: Our classification revealed 19 clusters of tall-forb vegetation in Middle Asia. Among others we found forb communities typical for Tian Shan, western Pamir-Alai, forb-scree vegetation of Pamir-Alai, dry tall-forbs and typical forbs of the alpine belt. A total of eight new tall-forb associations and five communities were distinguished. The forb vegetation of Middle Asia has been assigned to the class Prangetea ulopterae Klein. The main factors differentiating the species composition of the researched vegetation are elevation, mean annual temperature, sum of annual precipitation and inclination of the slope. Conclusions: The paper presents the first insight into the comprehensive classification of the alpine forb vegetation in Middle Asia and fosters progress in explaining the relationship of boreo-temperate and Mediterranean-like (Irano-Turanian) vegetation in western Asian and central Asian subregions of the Irano-Turanian phytogeographical region. Taxonomic references: The nomenclature of the vascular plants follows generally Cherepanov (1995) and for Bromus spp. The Plant List (2020) Version 1.1. http://www.theplantlist.org/. Syntaxonomic references: The names of syntaxa are used in accordance with Ermakov (2012), Gadghiev et al. (2002) and Nowak et al. (2018). Abbreviation: NMDS = Non-metric Multidimensional Scaling

    Distribution, ecology and conservation status of Dionysia involucrata Zaprjag., an endangered endemic of Hissar Mts (Tajikistan, Middle Asia)

    Dionysia involucrata Zaprjag. (Primulaceae) is known as critically endangered endemic species of Hissar Mountains in Tajikistan. It is reported from few localities mainly in Varzob River valley and its tributaries. The species inhabits steep or overhanging faces of granite rocks in narrow river gorges. During the research all known populations of D. involucrata were examined in respect of the habitat conditions and species composition of vegetation plots. We analyzed the population extent of the species in its range in Tajikistan and the main threats in order to assess its conservation status. The detrended correspondence analysis was performed on a matrix of 65 relevés and 49 species (vascular plants and mosses), to classify the phytocoenosis with domination of D. involucrata according to their floristic composition in relation to other petrophytic vegetation units. Using our field data regarding present extent of occurrence and area of occupancy we conclude that the threat category of D. involucrata should be reassessed from critically endangered to endangered. The species shows decline tendency in extent of occurrence, area of occupancy as well as in number of locations. The vegetation plots with domination of D. involucrata have relatively high level of separateness due to different species composition. We define the new association – Dionysietum involucratae – representing chasmophytic vegetation of submontane and montane zone in Middle Asia (ca. 1000–1600 m a.s.l.). The plots of Dionysietum involucratae were found mainly on granite rocks, on very steep or overhanging faces, on southwestern or southern exposition. The association is rather poor in species with inconsiderable contribution of mosses. Despite the diagnostic species, Campanula incanescens, Carex koshewnikowii and Scutellaria hissarica were the most abundant and frequent taxa within the researched patches of vegetation
