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:
Three different approaches are formulated to obtain the bounds of the effective elastic moduli of nanoparticle-reinforced composites based on the CSA and the interface stress model. It is found that the effective bulk modulus can be obtained by all three different approaches but the effective shear modulus can be obtained only by the energy approach. The bounds of the effective bulk modulus coincide and depend only on the interface bulk modulus, while those of the effective shear modulus are distinct and depend on two interface elastic constants. Furthermore, limit analysis discloses that the bounds of the effective bulk modulus of nanoparticles coincide but deviate from the bulk modulus of particle in the classical case, and the bounds of the effective shear modulus are distinct in contrast to the effective bulk modulus of nanoparticles or both effective moduli of conventional composites.

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.

Detailed analyses of assemblages from graves of the Corded Ware culture on territories between the Vistula, Bug, and Dniester Rivers indicate the existence of various relations between people from different regions but also those living on the same area. However, the question of the character of these relations remains open.

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).

Opis:
The study was carried out from the beginning of June to the end of July 2005 in the Krasiborska Kępa reserve (UTM VV56; 53.848°N, 14.370°E). Three research plots were established, representing various types of use of reedy areas: an unused reedy area, a reedy area mown in summer, and an area mown in winter. Beetles were collected in Barber traps with ethylene glycol as a preservative liquid. Seven traps were set up in each examined habitat. In total 1,145 specimens belonging to 35 species were caught. The relatively small area presented three different carabid assemblages, differing in species richness, abundance, dominance structure and ecological preferences. The highest species richness and abundance, as well as the largest representation of endangered stenobiontic hygrophilous bog species (Trechus rivularis, Carabus clathratus, Carabus menetriesi, Bembidion fumigatum, Blethisa multipunctata, and Oodes helopioides), were observed in the  periodically flooded fen which was mowed in the winter.
W wyniku badań przeprowadzonych w czerwcu i lipcu 2005 roku, na trzech stanowiskach o charakterze torfowiskowym w północno-wschodniej części rezerwatu Karsiborska Kępa zebrano 1145 osobników należących do 35 gatunków. Na względnie małym terenie występują trzy różnych zgrupowania biegaczowatych. Różnice polegają na bogactwie gatunkowym, liczebności, strukturze dominacji i preferencjach ekologicznych. Największe bogactwo gatunkowe i liczebność, oraz największa reprezentacja przyrodnicza cennych stenobiontycznych higrofilnych torfowiskowych gatunków (Trechus rivularis, Carabus clathratus, Carabus menetriesi, Bembidion fumigatum, Blethisa multipunctata, Oodes helopioides) znajdowała się na stanowisku 3 – okresowo zalewanym torfowisku niskim, koszonym w okresie zimowym.

Opis:
This article focuses on the diatom assemblages and geochemical composition of sediment cores retrieved from the Pomeranian Bay. We also discuss similarities and differences in the diatom assemblages and the palaeogeographic development of nearby regions. Our main objective was to determine the characteristics and rate of the Littorina transgression in the Pomeranian Bay area. Sediments were divided into units based on differences in the distribution of diatom ecological groups and in geochemical ratios, such as Mg/Ca, Na/K and Fe/Mn. This study identified lacustrine sediments deposited during the time of the Ancylus Lake. This lacustrine-period sedimentation took place in a shallow lake under aerobic conditions. The record of the onset of marine environment dates to 8900–8300 cal BP and corresponds to the Littorina transgression. After about 8300 cal BP, sedimentation took place in a deeper marine environment with higher biogenic production and anaerobic conditions. The abrupt appearance of marine diatom species and increased geochemical salinity indicators reflect the large impact of the Littorina transgression on the Pomeranian Bay environment.

Opis:
The article presents an analysis of the construction of future scenarios in relation to conflict and communication technologies (CTs), on the basic of Delphi+ workshops and essay-writing sessions. Grounded in a theoretical reflection on the various forms of conflict—distinguishing between armed, grey zone and democratic conflict—in combination with theoretical reflections on the role of CTs in conflict, and the future imaginings of (communication) technologies, the analysis discusses six future imaginaries. Four of these future scenarios are negative as in a power take-over, the intensification of both an armed conflict, and of democratic conflict, and the harm inflicted on the environment and society in general. The two positive scenarios are the protective role of supranational organizations and cultural change. Together, these six scenarios form a map of how European experts are concerned about media/technology and military/technology assemblages, and how they place their hope in supranational political institutions and cultural change.
