Opis:
Despite the stereotype that an artistic stage of Cracow after World War 2 was dominated by Colourism, Surrealism, Tachisme and Matter Painting – distinctly present in the circle of the Second Krakow Group and its leader Tadeusz Kantor, and in the later period dominated by expressionistic figuration, we may also observe in the Cracow milieu a significant interest for cold Geometric Abstraction that is based on optical effects. Especially after 1960 we can follow in Cracow development of various tendencies in Geometric Abstraction to name only Op Art, Minimal Art or Post Painterly Abstraction. This development was undoubtedly affected by succeeding exhibitions of the International Print Biennial (at present Print Triennial) within which works from this artistic circle appeared next to popular in the 1960s Pop Art. Different versions of Geometric Abstraction were practised, for instance, by the following artists: Alina Kalczyńska, Ryszard Otręba and Jan Pamuła who, as one of the first artists in Poland, paid his attention to computer graphic art. The initiated in the 1960s trend for Geometric Abstraction in Cracow painting and graphics has been continued till today, being at the same time an alternative to figurative tendencies and multimedia art. The author discusses the succeeding generations of artists from Cracow dealing with Geometric Abstractionism, starting from emigrant artist Mieczysław Janikowski, who studied in Cracow as early as before the war and was a joint between inter-war and post-war avantgarde, and reaching at the Action of Abstraction Revaluation, undertaken by the Cracow gallery F.A.I.T in 2008–2009 with participation of the young- est artistic generation. Artists from Cracow, let it be Adam Marczyński and his apprentice Janusz Orbitowski, created geometric relief compositions. Jerzy Kałucki’s painterly Geometric Abstraction was accompanied by conceptual works and installations. The work of Adam Wsiołkowski is situated somewhere between abstraction and figuration and may be ascribed to the stream of Visualism. Nevertheless, what comes as characteristic for Polish artists focusing on Abstractionism is referring to the contents of a spiritual character, symbolic meanings of numbers and geometric figures. These tendencies may also be observed on the example of Cracow artists, to name but a few: Tadeusz Wiktor, Teresa Bujnowska, Andrzej Bednarczyk, Tamara Berdowska, Michał Misiak, and Beata Popławska.

Opis:
The article presents one of the strands of empirical research on the energy transition process conducted by an anthropologist in Upper Lusatia, in the Bogatynia municipality, in the area around the Turów mining and power complex. The perspective of transrelational ethnography makes it possible to weave together the various elements of this process and look at its changing environmental/economic, political and socio-cultural conditions. The text shows some of the many interweaves uncovered in the field, in the decarbonisation process, seen in the perspective of transrelational ethnography. It focuses on the ambiguities in the worlds of the region’s residents as brought to light in the study. The author draws attention to epistemological traps, such as the category of conflict, that await the anthropologist in a field that faces an uncertain post-coal future. Also, the author stresses the lack of preparedness of the volatile, conceptually unclosed field and its unstable, complex, assemblage architecture.
Artykuł przedstawia jeden z wątków badań empirycznych dotyczących procesu transformacji energetycznej prowadzonych przez antropolożkę na Górnych Łużycach, w gminie Bogatynia na obszarze wokół kompleksu wydobywczo-energetycznego „Turów”. Perspektywa etnografii transrelacyjnej pozwala na splatanie różnych elementów tego procesu i przyglądanie się jego zmiennym uwarunkowaniom środowiskowo-ekonomicznym, politycznym i społeczno-kulturowym. Tekst pokazuje kilka spośród wielu splotów odkrywanych w terenie w procesie dekarbonizacji widzianych w perspektywie etnografii transrelacyjnej. Koncentruje się na niejednoznaczności klarujących się w badaniu lokalnych światów mieszkańców regionu. Zwraca uwagę na poznawcze pułapki, np. kategorię konfliktu, które czyhają na antropolożkę w terenie o niepewnej przyszłości po węglu. Tekst akcentuje przy tym niegotowość zmiennego, konceptualnie nie domkniętego terenu oraz jego niestabilną, złożoną – asamblażową architekturę.

Opis:
Up to now only little attention was dedicated to the study of the trace fossils in the development of the Central Carpathian Paleogene Basin in the Orava region. Occasional trace fossils findings from the Central Carpathian Paleogene formations in the Orava and others regions were referred by Plička (1987). Other specialized works on trace fossils from these formations from the Orava region were not published. Study of trace fossils is strongly influenced by the existence of well exposed outcrops within individual formations. The best exposed outcrops are situated in the basal Borové Formation as well as in the higher parts of Paleogene sequences – mainly in the Zuberec Formation. This preliminary study shows a relatively rich diversity of trace fossils associations across the Central Carpathian Paleogene Basin. We present new finds of trace fossils, within which we have classified 7 ichnogenera, 11 ichnospecies and 2 types of trace fossils, which were not closely systematically classified. Many trace fossils identified in the Orava region are typical for some palaeoenvironments, which are characterized by a specific lithology, nature of the substrate, dynamics of the environment, amount of nutrients and stability or fluctuations of oxygen in the bottom waters. The trace fossils assemblages reflect changes of depositional systems during the tectonic and sequence stratigraphic development of the basin. Early Eocene shallow-sea environment of the Borové Formation including the rocky coast, sandy dynamic littoral, transition - al and internal shelf zones are characterized by findings of traces of Entobia, Gastrochaenolites, Nummipera, Ophiomorpha and Skolithos. On the contrary, a significant deepening of the deposition environment during the Oligocene, documented by turbidite sedimentation of Zuberec and Biely Potok formations is characterised by findings of graphoglyptids ( Spirorhaphe, Nereites, Paleodiction, Protopaleodictyon, Megagrapton ) or traces of deposit feeders ( Arthrophycus, Chondrites, Planolites, Phycodes, Scolicia, Zoophycos).

Opis:
Artykuł stanowi analizę performatywności dwóch ikon kompozytowych w kontekście liturgicznym i w kontekście muzealnym. Ich niezwykła forma polegająca na połączeniu dwóch paneli w jedno dzieło sztuki jest interpretowana jako asamblaż – w ślad za użyciem tego terminu przez Victora I. Stoichitę. Jednocześnie autorka akcentuje wieloznaczność tego terminu i korzysta z teorii asamblażu jako narzędzia interpretacyjnego, by ukazać funkcjonowanie ikon w ramach asamblaży społecznych. W perspektywie tej teorii można analizować aktywne uczestnictwo ikon kompozytowych w asamblażach ludzi i nie-ludzi oraz sprawczy potencjał tkwiący w ich niezwykłej formie, by pogłębić rozumienie ich funkcjonowania w relacjach z innymi dziełami sztuki, instytucjami, ludźmi. Dzięki zastosowaniu kategorii asamblażu i ikony performatywnej do analizy dwóch przykładów ikon kompozytowych w artykule scharakteryzowano wpływ asamblażowej formy na kult i prezentację obrazów. Skupienie się na kwestii performatywności pozwoliło uwydatnić dynamikę formy asamblażowej i ikony samej w sobie. W zależności od kontekstu – performansów, w których uczestniczy, a także asamblaży, których staje się częścią – ikona będzie dziełem sztuki i/lub obrazem dewocyjnym, który przekracza sferę wartości artystycznych. W artykule poddano także refleksji asamblażowy charakter procesu badania ikon.
This article analyzes the performativity of two composite icons in liturgical and museum contexts. Their unusual form, consisting of two panels combined as one work of art, is interpreted as an assemblage, following Victor I. Stoichita use of the term. Moreover, the multivalency of the term assemblage is used to present the icons as part of dynamic social assemblages by applying the theoretical perspective of assemblage theory. It becomes crucial in seeing them as active agents in the assemblages of humans and non-humans as well as understanding the potential of this unusual form and the way they function in various relations with other works of art, institutions, and people. Applying the categories of assemblage and performative icon to the analysis of two examples of composite icons, the article characterizes the influence of assemblage form on the veneration and presentation of icons. Focusing on the issue of performativity, agency, and affordance made it possible to highlight the dynamics of the assemblage form and the icon itself. Depending on the context—the performances in which it participates and the assemblages of which it becomes a part—the icon can be perceived as a work of art and/or a devotional image that transcends the realm of artistic values. The article also reflects on the assemblage nature of the icon research and study process.

Opis:
Celem artykułu jest wyodrębnienie nowej, nieantropocentrycznej formy pisania o przyrodzie. Analizując teksty antropolożki Anny Lowenhaupt Tsing, biolożki Urszuli Zajączkowskiej, historyczki nauki Helen Macdoland i filozofki Jolanty Brach-Czainy – wskazuję na chwyty charakteryzujące ich biopoetykę: immersyjność, rizomatyczność, asamblażowość i tentakularność. Nawiązując do formuły gatunkowej “pasażu tekstowego” (rozumianego szeroko, niekoniecznie jako pisanie i czytanie miasta) i wspierając się rozważaniami Rebeki Solnit, pokazuję, jakim ponadgatunkowym doświadczeniem jest dla flanerek wędrówka i włóczęga, które mogą zarazem być ucieczką z laboratorium. Zastanawiam się też, jak bardzo nieantropocentryczny może być tekst literacki.
he aim of this paper is to describe new, non-anthropocentric forms of non-fictional nature writing that can also be interpreted as life-nature (autoBIOgraphical) writing. The author discusses the works of Anna Lowenhaupt Tsing (anthropologist), Urszula Zajączkowska (biologist), Helen Macdonald (historian of science) and Jolanta Brach-Czaina (philosopher) in order to show their biopoetical writing strategies: immersion, rhizomatic, assemblage, and tentacularity. In her analysis, the author defines the strategies by using the concepts of Passage – understood in broader terms rather than as a trope of urban writing and reading – and flaneurie, which can be a non-urban experience, that represents the opposite of laboratory. This paper will also discuss the possibilities and the limits of non-anthropocentrism in literature.

Opis:
The composition and structure of the breeding bird community in the Borki Forest in north-eastern Poland were investigated during two separate periods: 1994–1996 and 2012–2014. Bird censuses were carried out in three plots located in mature oak-hornbeam, ash-alder and mixed coniferous forest stands. A standard combined mapping technique for estimating the number of breeding birds was applied. A total of 74 bird species bred at least once within any plot during 1994–1996 or 2012–2014. The structure of the bird assemblages on particular plots displayed a high degree of similarity, exceeding 75%, which means that they represent essentially the same bird community. However, the investigated assemblages have changed substantially over the 20 years. Both, the number of breeding bird species and the population densities on all plots, were much higher in 2012–2014 than in 1994–1996. The mean number of breeding species on all plots was over 50% higher in 2012–2014 than in 1994–1996, whereas the mean total density of breeding pairs increased by more than 60%. Total population densities on the plots increased as a result of an increase in population densities of individual bird species combined with an increase in the number of breeding species. Due to different rates of population growth for certain species, also the composition of dominating species group have changed. The observed changes in the avifauna of the Borki Forest were most probably due to an enrichment of the forest habitats structure, which was caused by natural factors, such as ageing of forest stands, forest succession and a change in water regime by beaver dams, as well as by forest management, including group felling within or in the vicinity of plots and uncovering of the forest edge.

Opis:
This paper reports the results of X-ray diffraction quantitative mineralogical studies of the clay-rich Middle Jurassic sedimentary rocks from Gnaszyn, central Poland and their palaeoenvironmental interpretation. The palaeoenvironmental interpretation is aided by the fact that the sediments have not been significantly altered by diagenesis. The mineral composition is uniform throughout the succession: quartz, K-feldspar, plagioclase, calcite, gypsum, anhydrite, pyrite, illite, kaolinite, chlorite, and glauconite. The clay assemblage is dominated by illite, which alone accounts for about 20 wt% of the total mineral content. Kaolinite amounts usually <10 wt% and chlorite and glauconite occur in subordinate quantities. The clay mineral assemblage is largely of detrital origin and indicates rather cool and/or dry climatic conditions favouring mechanical erosion of the source rocks.

This auto-ethnographic description of the experiences in the development of the teaching and learning approach, at the postgraduate level, introduces the impact of the community of practice in the development of the learning processes in South Africa, with an international view. The principles of community of practice are outlined and the theoretical grounding is provided in terms of the notion of assemblage theory, the definitions of fundamental and derivative epistemic authority, as well as the assemblage boundary and the personal intents of the community of practice members. The theoretical grounding is then applied through several iterations of the community of practice between 2006 and present. The adaptive nature of the community of practice as an assemblage and the function as a sociology-of-knowledge system are outlined.

Opis:
The major impacts on aquatic ecosystems worldwide caused by land use lead to changes in their natural conditions and limitation of water use for various needs. This paper presents the results of the study of the physical and chemical parameters and macroinvertebrate assemblage in the White Drin River (or: the Drim River, Alb. the Drini i Bardhë River) basin, the largest in Kosovo. Macroinvertebrate sampled at 11 sites in the river resulted in 5946 collected benthic organisms, which in taxonomic terms belong to 12 orders and 51 families. Of the total number of organisms, 72.28% were Insects, 25.39% Amphipoda crustaceans and 2.33% were Annelide worms and Mollusk. The used biotic indices Biological Monitoring Working Party (BMWP), Ephemeroptera, Plecoptera, and Trichoptera (EPT), average score per taxon (ASPT) and Stroud Water Research Center (SWRC) classify water quality in excellent category in the sampling site S1 near the source of the White Drin River, whereas in other sampling sites, as a result of pollution, water quality varies on category II–IV. The Pearson's correlation analyses shown that the physical and chemical parameters affect the water quality and the composition of macroinvertebrates. Our results show that the parameters that adversely affect the BMWP, EPT and ASPT biotic indices as well as the Shannon–Wiener, Mergalef and Menhinik diversity indices are: pH, electrical conductivity (EC), total suspended solids (TSS), nitrates (NO3) and chlorides (Cl). We can conclude that the anthropogenic impact on White Drin basin affects the physical, chemical and biological parameters of the water therefore these parameters should be constantly included in Biomonitoring and Management plans for water resources in Kosovo.

Opis:
Detrital zircon age of the conglomerates from the Upper Silesian (USB) and Małopolska (MB) (S Poland) have been investigated to compare their deposition age and possible provenience. The size and poor sorting of the lithoclasts reflect a short transportation, with deposition close to the sourceland. The Late Ediacaran conglomerate of the Potrójna IG 1 and Raciechowice 1 boreholes (USB) reveal a good match between the ages known from the local basement explored by boreholes. Detrital zircon clusters in a range of 579-585 Ma and 628-638 Ma and of 707 Ma are consistent with the distributions of Cadomian magmatism within the nearest orogenic belt or those identified elsewhere within the Brunovistulicum. In case of the conglomerate deposited in the Batowice 2 borehole (MB), the zircon clusters of 532, 551, 594 and 649 Ma, accompanied with a pre-Svecofennian group peaked at 2071 Ma, and the lack of Sveconorvegian population may document a tectono-sedimentary interaction between the Baltica's southern margin and the Gondwanan Cadomian and Late Cadomian basement during Early Paleozoic time. This conglomerate bed was deposited later, after the Early Ordovician, then docking of Małopolska Block - Baltica was probably completed.

Opis:
The present study investigates the influence of seasonal dynamics on macrobenthic assemblages in four seasons of 2017—2018 from the central sector of Indian Sundarbans which is under the constant threat of climate change. Besides taxonomic analysis, a traitbased approach has also been applied to assess the change in their ecosystem functioning. The maximum species density (11675 ± 11883.31 ind. m−2) was observed during the spring season which declines considerably in the monsoon season (5875 ± 6224.08 ind. m−2). A total of 95 macrobenthic taxa were recorded from Sundarbans and they were dominated by families like Capitellidae, Donacidae, Magelonidae, Nereididae, Paraonidae and Spionidae. Overall, polychaetes have shown higher taxonomic and functional variation than other groups. Opportunistic polychaete species have shown a prominent compositional shift during post-monsoon seasons. Both the univariate and multivariate analyses have shown a significant relation between macrobenthic composition and environmental parameters. SIMPER has depicted that environmental parameters made the station 4 unique for several types of molluscs like Acteocina estriata, Stenothyra deltae and Meretrix meretrix during spring. Trait percentages also showed a seasonal succession pattern and among the trait categories, burrowers and deposit feeders dominated the estuary. A gradual increase in suspension feeders in spring has been noticed. RLQ approach with fourth-corner analysis was used to unravel the relationship between traits and environmental parameters. Hence, the present study provided a comprehensive idea about the species composition along with their trait categories from such a dynamic habitat. That could be the first stepping stone for a long term monitoring of macrobenthic assemblages from this largest delta on earth.

Opis:
The presented paper analyses the occurrence of dragonflies in the left-bank (Polish) part of the Bug River valley between Włodawa and Kodeń (65 km of the river course, 51°32’–51°55’ N, 23°31’–23°38’ E). In total, 40 species were recorded. The key sites for dragonflies were oxbow lakes, the Bug River and its tributaries. Species diversity was found to be relatively low due to a lack of peat lands and dystrophic waters, as well as strong astatism of small water bodies. The effects of strong water pollution in the Bug River were evident. The species composition of dragonflies was typical, but densities of Gomphidae (particularly Ophiogomphus cecilia ) suggested an adverse state of the environment. This is caused by surface runoffs of agricultural wastewater in Poland, but also by strongly polluted rivers in the territory of Ukraine. The study includes a review of earlier research conducted in the upper course Bug River valley. Considering both the old and new data, 54 dragon fly species were recorded in the Middle Bug River valley between Gołębie and Kodeń (246 km of the river course at the border of Poland with Ukraine and Belarus). It is an area of high importance for the protection of dragonflies in terms of species diversity and species assemblages.
Analizowano występowanie ważek w lewobrzeżnej (polskiej) części doliny Bugu pomiędzy Włodawą i Kodniem (65 km biegu rzeki, 51°32’–51°55’ N, 23°31’–23°38’ E). Wykazano 40 gatunków. Kluczowe dla występowania ważek były: starorzecza, rzeka Bug i jej dopływy. Stosunkowo małe bogactwo jakościowe odonatofauny wynikało z małego zróżnicowania siedlisk, zwłaszcza z braku torfowisk i wód dystroficznych oraz z silnego astatyzmu drobnych zbiorników. Widać było skutki silnego zanieczyszczenia wody w Bugu: skład gatunkowy ważek był prawidłowy, ale zagęszczenia Gomphidae (zwłaszcza Ophiogomphus cecilia) wskazywały na niekorzystny stan środowiska. Jest to powodowane przez spływy powierzchniowe ścieków rolniczych w Polsce, ale też silne zanieczyszczenie rzeki jeszcze na obszarze Ukrainy. Omawiane prace były kontynuacją wcześniejszych badań, prowadzonych w dolinie Bugu w wyższym biegu rzeki. Podsumowując nowe i stare dane, w dolinie środkowego Bugu między Gołębiami i Kodniem (246 km biegu rzeki na granicy Polski z Ukrainą i Białorusią), stwierdzono 54 gatunki ważek, co stanowi 74% fauny Polski jak też 73% fauny Ukrainy i 86% fauny Białorusi. Jest to obszar o dużym znaczeniu dla ochrony ważek pod względem bogactwa gatunkowego i zgrupowań gatunków. Występuje tu niewiele ważek zagrożonych w Polsce, ale jest to istotny rezerwuar taksonów zagrożonych w Europie Środkowej: stwierdzono 62–79% gatunków z Czerwonych list krajów sąsiadujących z Polską.

Opis:
The detailed sedimentological study of the 150-m-thick Muschelkalk succession, deposited on a small (~200 by 80 km), morphologically diverse Upper Silesian carbonate platform during four major marine-transgressive pulses of the Tethys Ocean, enhanced the understanding of the depositional history, palaeogeography, and facies distribution. A total of thirty-five lithofacies types were identified, described and interpreted in terms of depositional settings. These different lithofacies represent various shallow-marine environments along the platform transect, from peritidal to offshore areas. The vertical and lateral organization of the lithofacies delineated was caused by the interplay of platform morphology, third-order eustasy and the long-term tectonic evolution of the area. Accordingly, the carbonate system studied is a good example of the influence of large-scale processes on the facies architecture of carbonate platforms. In general, all of the four Transgressive Systems Tracts are characterized by similarity in lithofacies composition and vertical succession and by minor lateral change, indicating only limited influence of the three large-scale factors mentioned on lithofacies development and distribution during transgressions. In contrast, each of the four associated Highstand Systems Tracts comprises an individual (unique) lithofacies assemblage displaying substantial regional and local variation, which indicates that the filling of accommodation space during highstands strongly depended on the extrinsic processes.

Opis:
Foraminiferal assemblages from the neritic environment reveal the palaeoecological impact of nutrient types in relation to shore distance and sedimentary setting. Comparatively proximal siliciclastic settings from the Boreal Domain (Brora section, Eastern Scotland) were dominated by inner−shelf primary production in the water column or in sea bottom, while in relatively seawards mixed carbonate−siliciclastic settings from the Western Tethys (Prebetic, Southern Spain), nutrients mainly derived from the inner−shelf source. In both settings, benthic foraminiferal assemblages increased in diversity and proportion of epifauna from eutrophic to oligotrophic conditions. The proximal setting example (Brora Brick Clay Mb.) corresponds to Callovian offshore shelf deposits with a high primary productivity, bottom accumulation of organic matter, and a reduced sedimentation rate for siliciclastics. Eutrophic conditions favoured some infaunal foraminifera. Lately, inner shelf to shoreface transition areas (Fascally Siltstone Mb.), show higher sedimentation rates and turbidity, reducing euphotic−zone range depths and primary production, and then deposits with a lower organic matter content (high−mesotrophic conditions). This determined less agglutinated infaunal foraminifera content and increasing calcitic and aragonitic epifauna, and calcitic opportunists (i.e., Lenticulina). The comparatively distal setting of the Oxfordian example (Prebetic) corresponds to: (i) outer−shelf areas with lower nutrient input (relative oligotrophy) and organic matter accumulation on comparatively firmer substrates (lumpy lithofacies group) showing dominance of calcitic epifaunal foraminifera, and (ii) mid−shelf areas with a higher sedimentation rate and nutrient influx (low−mesotrophic conditions) favouring potentially deep infaunal foraminifers in comparatively unconsolidated and nutrient−rich substrates controlled by instable redox boundary (marl−limestone rhythmite lithofacies).
