The paper presents the interpretation of a composite seismic profile recorded to 18 s TWT which crosses western Poland from the south to north. The interpretation is based on data along the profiles GB-2, GB-2B-96 and 25-III-82 collected between 1987 and 1996. Two reflection horizons bordering the crystalline crust have been recognized: in the top - SK, and in the base (Moho - M). The Caledonian complex is distinguished in the northern part of the profile GB-2 north of the Dolsk Zone. The results obtained allow determination of crustal structure down to the Moho. Several deep fault zones have been delimited (in the regions of Dolsk, Szamotuły and Trans-European Fault) which cut the entire crust. Crustal thickness ranges from approximately 30 km in the Palaeozoic platform up to about 40 km along the Trans-European Suture Zone.

The first site in western Poland with a red till lithotype has been discovered in the Trzebnica Hills, southwestern Poland. This is a clay-rich, red till with dominant East-Baltic material (East-Baltic lithotypes). The red till forms the uppermost part of the Borowiec Till, a till from the Sanian 2 (Elsterian) Glaciation. Moreover, some Borowiec tills in the Barycz River valley (north) and the Prosna River valley (east) contain in their uppermost parts a dolomite-rich horizon, which, although only greyish-brown, also represents the East-Baltic till lithotypes. The late Elsterian ice sheet in Poland was developed as several ice-lobes with different ice dynamics. The lobes from western Poland advanced to their maximum extent earlier than the eastern lobes. In the latest phase of the glaciation, the western lobes retreated, while the eastern ones advanced from NE to SW. Their presence is proved by deposition of the Borowiec Till and East-Baltic till lithotypes.

The aim of this paper was to evaluate the intensity of rural area marginalisation. As a study region, Western periphery of Poland has been chosen. The spatial scope of the research covers three border voivodeships: Dolnośląskie, Lubuskie and Zachodniopomorskie, however, the study was conducted at the local level, including 310 rural and rural-urban gminas (administrative region of the 3rd order in Poland). The statistical data were derived from the Central Statistical Office from the period of last two decades. Results revealed the differences in the level of rural area marginalization and were analysed in terms of agricultural and socio-economic aspects.

The Białowice site is situated in the north-west of the Nowa Sól Depression which is part of the Central Poland Lowlands. Palynological analysis shows that lake and swamp accumulations took place in the Early Vistulian. Two warm interstadial-rank oscillations (Brörup and Odderade) and a stadial (Rederstall) have been distinguished during the Early Vistulian. The sequence of changes at Białowice is similar to the sequences in profiles from other parts of Poland and Western Europe. Until now, in that region of Poland the vegetation succession of the Brörup and Odderade had remained unknown. The lithology of the profile at Białowice shows rapid changes of sedimentation which have been observed in the younger part of the Brörup and at the Brörup/Rederstall transition. Geological and palynological data suggests that the maximum limit of the Vistulian Glaciation to the south of the Żary Hills.

Palaeomagnetic research on the lower and middle Buntsandstein section of the Gorzów Wielkopolski IG 1 borehole, located in middle western Poland, showed the possibility of existence of short reversed subzones within the first normal polarity zone of the lowermost Buntsandstein (magnetozone Tbn1). The earlier established magnetozones Tbn2 and Tbn4 were not detected. The stratigraphic gap between the middle and upper Buntsandstein included at least magnetozones Tbn6 and Tbr6. The magnetostratigraphic correlation between the investigated section and the Otyń IG1 section indicates a substantial diachronism of palynostratigraphic zones based on macrospores in the lowermost and middle Buntsandstein.

Petrological studies of siderite layers and concretions occurring in the Early Jurassic periodically marine deposits, described as the brackish shelf facies (Feldman-Olszewska 1997), were conducted. The analyzed rocks are mainly built of the sideroplesite, while siderite and pistomesite occur sporadically. Two generations of the sideroplesite were distinguished, that essentially differ due to the size of the rhombohedra. The older generation forms micritic concretions and micritic layers of the clayey siderites. The younger generation either represents a groundmass of the sparry siderites or cements of the sideritic sandstones. Some layers of siderites contain ooids and aggregates of the chamosite and phosphates, chamosite intraclasts, pyrite, detrital quartz and micas. Numerous shells of foraminifers and occasionally molluscs are present, too. Nine samples of the clayish siderites from the Mechowo IG1 borehole were isotopically analyzed aiming at oxygen and carbon ratios. The recognition of δ18 O of crystallization waters responsible for the siderite formation was the final aim of the studies. A formula given by Carothers et al. (1998) as well as the results of studies on the siderites of Baker et al. (1995) were applied. It results from the calculations that the δ18 O of the crystallization water oscillated between -12 and -3‰ SMOW in the Late Sinemurian, while in the Early Pliensbachian and the Early Toarcian it changed from -10 to +2‰ SMOW. That points to the meteoric waters gradually enriched in the 18 O isotope. The δ13C values in the siderite samples oscillate from -0.85 to -10.57‰ PDB. That suggests that the pore waters were enriched in carbon formed in the microbiological zone of the metanogenesis due to the alteration of the organic matter (Longstaffe & Ayalon 1997). The whole petrological analysis of the siderites points to their origin as the product of the diagenetic processes which operated in the bottom mud of the shallow brackish basins in the anoxic conditions with the influence of the meteoritic waters.

Sediments, being the most important source of phosphorus (P) in the shallow (max. depth 7.2 m), polymictic Swarzędzkie Lake during the summer, were thoroughly studied in laboratory experiments with intact cores sampled at 7 stations in four seasons of the year. Under anaerobic conditions P release rates peaked in the samples from the deepest part of the lake at 26.86 mgP m⁻²d⁻¹. However, the highest rates were determined at one of the littoral sites (near the mouth of a polluted stream) at 59.5 mgP m⁻²d⁻¹. Littoral P release coincided with occasionally low oxygen concentrations (0.2 mgO₂ l⁻¹) above the bottom. On the scale of the whole lake, P release from the littoral zone, where both temperature and oxygen concentration were highly variable, had the strongest influence on the trophic state. It accounted for 63% of the annual internal load but only 55% of total lake area.

W pracy przedstawiono analizy czynników środowiskowych, które wpłynęły na lokalizację czterech wybranych grodzisk wczesnośredniowiecznych, położonych w centralnej części Polski Zachodniej. Badano następujące obiekty: grodzisko w Bobrownikach, usytuowane na granicy Pradoliny Warciańsko-Odrzańskiej i Wzniesień Zielonogórskich, następnie obiekt w Bytomiu Odrzańskim leżący w dolinie Odry na terenie Pradoliny Głogowskiej oraz grodziska w Solnikach i Popęszycach znajdujące się na Wzgórzach Dalkowskich. W terenie przeprowadzono badania geomorfologiczne i z zakresu geologii czwartorzędu, inne czynniki środowiskowe, takie jak hydrologia, gleby, potencjalna roślinność naturalna analizowano na podstawie źródeł literaturowych i kartograficznych. Za dominujący czynnik uznano rzeźbę terenu, bardzo istotną dla zapewnienia położenia obronnego grodom w Bobrownikach, Solnikach i Popęszycach. W dwóch przypadkach (Solniki i Bobrowniki) wyszukanie odpowiednich form terenu, takich jak ostrogi denudacyjne i wysokie krawędzie erozyjne, umożliwiło organizację grodziska niemalże bez wznoszenia wałów obronnych. Oprócz rzeźby terenu ważne były także elementy hydrologiczne (przebieg koryt rzecznych i rozmieszczenie podmokłości oraz bagnisk na dnie dużej doliny rzecznej), zapewniające obronne położenie obiektowi w Bytomiu Odrzańskim. Pozostałe czynniki naturalne miały niejednoznaczny i generalnie mniejszy wpływ na lokowanie grodów we wczesnym średniowieczu w centralnej części Polski Zachodniej.

The paper presents environmental factors that influenced the location of four selected early medieval strongholds in central Western Poland. The following objects were examined: a stronghold at Bobrowniki, on the border between the Warta-Odra Pradolina and Zielona Góra Hillocks, a stronghold at Bytom Odrzański in the Odra River valley within the Głogów Pradolina, and strongholds at Solniki and Popęszyce in the Dalków Hills. Geomorphic and Quaternary research was carried out during fieldworks, while other environmental factors were analysed from literature and cartographic sources. The relief was considered the dominant factor; it was very important to provide a defensive location for the strongholds at Bobrowniki, Solniki and Popęszyce. In two cases (Solniki and Bobrowniki), finding suitable geomorphological forms, such as intervalley rims and high erosional edges, enabled the stronghold to be settled almost without building ramparts. Besides relief, hydrology was also important (the course of river channels and the distribution of wetlands and marshes at the bottom of a large river valley), which ensured the defensive location at Bytom Odrzański. Other natural factors had an ambiguous and generally smaller impact on the settlement of strongholds in the early Middle Ages in central Western Poland.

It is in the first part of the study that there were presented external conditions for the cooperation arising from the regulations of the most important European and Polish program documents of the time horizon up to 2020. The next part presents synthetic social and economic characterization of the macro-region of Western Poland. Subsequently, the concept and the objectives for the creation of the supraregional strategy were presented. It is at present that the Development Strategy for Western Poland and the Development Strategy for Southern Poland for the Śląskie and Małopolskie Voivodeships are being created. These initiatives are bottom-up actions of the self-government bodies of the voivodeships that allows for implementing the model of the multilevel governance and the strategic partnership of the domestic and regional system. These are the first cooperation projects amongst macro-regions in Poland initiated from the bottom up and voluntarily by self-government authorities, in which the voivodeships acknowledge that their development should take place through joint actions taken in the entire macro-region and creating the synergy effect. These are very innovative actions against the background of the experience at programming the regional development in Poland.

Purpose: The aim of this paper is to show the positive impact of public support for the relationships within the triple helix model on the local development of Western Poland (WP). Design/methodology/approach: The paper presents the econometric model based on backward stepwise multiple regression in which the explanatory variables were expenses aggregated into 44 categories dedicated to triple helix model. The model defines a theoretical framework for local innovation systems in 111 counties of WP (5 western voivodeships). An economic aggregate based on average salaries was chosen as a dependent variable, treated as a measure of local development. Findings: Relationships diagnosed within triple helix model were supported by public expenditures from the European Union cohesion policy in 2007-2013. Two hypotheses were proposed in the paper. In the first one, a presumption was expressed for the positive impact of statistically significant expenditures on innovative activity, and technical and knowledge infrastructure for the local development of WP. The hypothesis was tested in basic and extended variants. In the second one, a presumption was expressed in which public expenditures on technical infrastructure were more influential for the local development of WP than expenditures on knowledge infrastructure. The first hypothesis was confirmed in both basic and extended variants. The second hypothesis could not be confirmed as a result of the research procedure. Importantly, bi-lateral synergy effects in the triple helix model within the researched counties of WP, positively influencing local development, are evident. Research limitations/implications: The Triple helix model, treated as a template for creating local innovation systems, could be extended into quadruple helix model. Future research may include variables related to “society” as forth side supporting innovative processes in local economy. Practical implications: The results of the regression model confirm the positive impact of expenses related to the broadly understood innovation activities on local development. In contrast, expenditure on technical infrastructure, representing the administration–business relationship, demonstrates a negative impact on the adopted local development measures. Originality/value: the paper presents the methodology, that could be used in diagnosing trilateral relationships occurring at the interface of science–business–administration. In the research, only bilateral relations have been diagnosed at the interface of science–business and administration–science.

The paper presents characteristics of the development level in rural and urban-rural communes, situated in border areas of three Voivodeships in western Poland (Zachodniopomorskie, Lubuskie and Dolnośląskie). In order to classify and compare rural areas, Hellwig’s synthetic measure was used. The analysis showed that communes with a high level of development are concentrated mainly in the Zachodniopomorskie Voivodeship, including Szczecin’s suburban area as well as the Baltic coastal zone.

Badania geochemiczno-petrograficzne ujawniły powszechne występowanie amorficznych stałych bituminów w skałach węglanowych dolomitu głównego w Polsce zachodniej. W skałach macierzystych i złożowych różnych rejonów Niżu Polski stopień przeobrażenia stałych bituminów obejmuje przedział od 0,88 %(zakres okna ropnego) do 3,26% R° (zakres generowania gazu metanowego) w skali refleksyjności witrynitu. Skały macierzyste zawierają na ogół do 1% TOC i charakteryzują się niskimi wartościami parametrów Rock-Eval: S2 (do 1,85 mg HC/g skały) i HI (do 200 mg HC/g TOC). Podział substancji organicznej na frakcje węglowodorowe umożliwia wydzielenie stałych bituminów w złożach ropy naftowej lub złożach uległych wcześniejszej destrukcji. Zastosowane techniki mikroskopowe UV i VIS dokumentują występowania tego typu substancji organicznej w przestrzeni porowej, mikroszczelinach i spękaniach oraz impregnacji w postaci struktur spływowych. Utwory zawierające stałe bituminy wykazują redukcję własności zbiornikowych (porowatości) i filtracyjnych (przepuszczalności).

Geochemical and petrographical investigations revealed common occurrence of amorphic solid bitumen in the Zechstein Main Dolomite carbonate rocks in the western part of Poland. Solid bitumen was created as a result of gas deasphalting or thermal cracking processes. In source and reservoir rocks in different Polish Lowland areas the solid bitumen maturity covers the range from 0,88% (oil window) to 3,26% R° (dry gas generation) in vitrinite reflectance scale. Generally source rocks contain up to 1% TOC and have low Rock-Eval parameter values: S2 (up to 1,85 mg HC/g rock) and HI (up to 200 mg HC/g TOC). Organic matter division on hydrocarbon fractions enables differentiation of solid bitumen in crude oi1 deposits or in deposits which underwent a destruction. Applied UV and VIS microscopic techniques confirmed such organic matter occurrence in pore space, microfractures and fissures and as impregnations of flow-like textures. Deposits containing solid bitumen indicate a reduction of reservoir (porosity) and transportation (permeability) properties.

The trepostome bryozoan Dyscritella microstoma Ernst, 2001 is reported for the first time from the Zechstein Main Dolomite (Ca2) of Poland and Germany. This species has been previously recognized in the older fossiliferous Zechstein Lime stone (Ca1) of the North Sudetic Basin (Poland) and in the northern part of Germany. The Polish specimens derive from a few boreholes located in the Pomerania region and in the Wolsztyn High, both in the western part of Poland. The German material comes from a borehole on Rügen Island in North eastern Germany. The present paper deals with the taxonomic description of D. microstoma and its distribution in the Main Dolomite deposits.

Wykonano badania petrograficzne skał czerwonego spągowca górnego z 76 otworów wiertniczych. W piaskowcach i zlepieńcach określono udział poszczególnych składników spoiw w celu rozpoznania ich roli w ograniczaniu właściwości zbiornikowych. Wyróżniono tu pelitowo-aleurytowe składniki allogeniczne, czyli matriks, oraz minerały autigeniczne - cementy. Wyliczono minimalne i maksymalne udziały poszczególnych rodzajów spoiw w skałach z badanych profilów wiertniczych oraz przedstawiono ich lateralną zmienność. Zawartość matriksu w analizowanych osadach waha się w granicach od 0,0 do 47,5% obj. Największy jego udział stwierdzono w skałach z rejonów Parzęczewa, Klęki i Siekierek na monoklinie przedsudeckiej oraz w strefie Bielica-Wysoka Kamieńska na Pomorzu Zachodnim. Cementy węglanowe (0,0-49,6% obj.), reprezentowane przez kalcyt i dolomit, dominują na Pomorzu Zachodnim, podobnie jak cementy siarczanowe (0,0-29,5% obj.). Najwyższy udział cementu kwarcowego (20,7% obj.) stwierdzono na Pomorzu w skałach z otworu Słowieńsko 1, natomiast w skałach z obszaru monokliny przedsudeckiej rzadko przekracza on 10% obj. Cementacja osadów węglanami, siarczanami i kwarcem powodowała znaczne ograniczenie porowatości skał, jednakże powszechna działalność diagenetycznego rozpuszczania przyczyniła się do zachowania ich zdolności filtracyjnych. Autigeniczne minerały ilaste w osadach Pomorza Zachodniego są reprezentowane głównie przez kaolinit i chloryty, a illit i minerały mieszanopakietowe illit/smektyt (I/S) występują podrzędnie. Diagenetyczny illit jest z kolei rozpowszechniony na obszarze monokliny przedsudeckiej, gdzie występuje obok chlorytów i minerałów I/S. Illit ten, obecny najczęściej w postaci włókien tworzących w przestrzeniach porowych mikrostruktury siatkowe, najsilniej ogranicza przepuszczalność osadów, często redukując ją całkowicie.

Petrographic research was performed on Upper Rotliegend rocks from 76 boreholes. The contribution of individual components of cements and the sum of matrix was determined for sandstones and conglomerates to recognize their role in reservoir quality reduction. Allogenic pelitic-aleuritic components i.e. the matrix, and authigenic minerals i.e. the cements have been identified. The minimum and maximum contents of individual cement types were measured and their distribution is presented in maps. The matrix content in the deposits varies from 0.0 to 47.5% vol. The highest values were recorded in the Parzęczewo, Klęka and Siekierki environs of the Fore-Sudetic Monocline, and in the Bielica-Wysoka Kamieńska zone of Western Pomerania. Carbonate cements (0.0-49.6% vol.), represented by calcite and dolomite, and sulphate cements (0.0-29.5% vol.) are dominant in Western Pomerania. The highest content of quartz cement (20.7% vol.) is observed in Pomerania (Słowieńsko 1 borehole). In the Fore-Sudetic Monocline region, it rarely exceeds 10% vol. Carbonate, sulphate and quartz cementation resulted in considerable reduction of the rocks porosity, however commonly operating diagenetic dissolution allowed them to keep their filtration ability. Authigenic clay minerals are represented in the rocks of Western Pomerania largely by kaolinite and chlorite. Illite and mixed-layers illite/smectite (I/S) minerals occur in minor proportions. Diagenetic illite, accompanied by chlorites and I/S minerals, is commonly observed in the Fore-Sudetic Monocline. This illite, represented mostly by fibres forming meshwork microstructures in the pore space, was the strongest reducing factor of permeability, often destroying it completely

The stomach content of 74 wild boars harvested in the Zielonka Game Investigation Centre in 2005-2007 were analyzed. According to the hunting management schedule and the cycles of forest and farmland food occurrence, three research seasons were selected and compared with respect to the trophic behaviour of wild boar. As many authors claimed, the animals extraordinarily tended to eat mainly the feed supplied to the forest. Such a disruption in the natural use of the food niche in the forest environment, resulting from an irrational feeding policy, interferes with the natural trophic role of this species.

Potwierdziło się przekonanie wielu autorów o nadzwyczajnej skłonności tych zwierząt do korzystania z karmy wykładanej w lesie. Zakłócenia naturalnego sposobu wykorzystywania niszy pokarmowej środowiska leśnego za sprawą nieracjonalnego dokarmiania wynaturzają przyrodzoną rolę troficzną tego gatunku.

In this study, generic composition of food and foraging preferences of the European beaver were determined on sites where the beavers were reintroduced after more than 200 years of absence. Research area was located on lowland (Silesian Lowland) and highland habitats (Bystrzyckie Mountains, Wałbrzyskie Mountains) in western Poland. During the study period, 17,418 trees and shrubs growing within the feeding area of the beavers were marked, out of which 4,669 were found to be cut by beavers. The results showed that the foraging preferences of beavers depend on the availability and diversity of the local food sources. In the lowlands beavers preferred the following species of trees and shrubs as their primary food source: Salix cinerea, S. fragilis, S. caprea, Cornus sanguinea and Populus tremula. In the highlands, beavers preferred Corylus avellana, Sorbus aucuparia, and Fagus sylvatica due to the low availability of Salix and Populus species. Moreover, in the highlands, beavers had to cover longer distances to reach the feeding sites and had to cut trees with larger diameter than in the lowlands.
