Opis:
The specific name velunensis is established to encompass porcupine remains (Hystrix Linnæus, 1758) recovered from the Pliocene site of Węże 1 in southern Poland. The studied specimen was previously assigned either to H. primigenia (Wagner, 1848) or H. depereti Sen, 2001, however it can be distinguished from these species and other fossil Hystricidae by its distinct occlusal morphology, most importantly the presence of an anterolingual flexus dissecting the anteroloph of P4. Hystrix velunensis sp. nov. was probably closely related to H. primigenia and H. depereti. A previously undescribed specimen from the nearby site of Węże 2 most probably belongs to H. refossa Gervais, 1852b, which would be the first known occurrence of this species in Poland.

Opis:
Conducted by "Olkusz" Speleological Club exploratory works related to the Gieńkówka cave led only to its partial opening. There are indications stating that this cave has continuation beyond its currently available parts. In order to verify those assumptions resistivity imaging method has been used. During analysis of the resistivity models obtained from field measurements the synthetic model, simulating the intersection of the cave corridor, has been utilized. In order to assess the reliability of resistivity cross sections in terms of the presence of artifacts left by the inversion process Depth of Investigation (DOI) index has been applied. For preparing DOI maps two inversions on the same data set were carried out using different reference models. Then the results were compared to each other. High resistivity anomalies revealed on obtained models show strong correlation with actual caves known in this area. In addition, similar anomalies have been found in place of the predicted continuity in Gieńkówka cave, thus confirming the hypothesis made in this research. High DOI index values in the occurrence of caves pointing to the instability of the inversion process in those areas.

Opis:
One of the most up to date scientific problems in recognition of karst processes is quantitave evaluation their activity. Basic and distinctive indicators that describe karst processes activity are intensity and magnitude of chemical denudation (Aksiom S.D., 2002). Not only a tool for describing changes taking place in the observed hydrogeological system will be presented in the paper but tools that allow to predict changes that may take place on the spur of the natural and anthropogenic factors. Only a few methods widely used in hydrogeology are also used in geography. In this paper authors present basis of geochemical modeling that can be widely used. Geochemical modeling can be divided into two main issues: Measurement, assessment and generalization of kinetic and thermodynamic data for solid phases (e.g. minerals), gases and solutions; Use of above data in numerical algorithms describing natural and anthropogenicly changed systems of interaction between water and matrix (Macioszczyk, Dobrzyński, 2006). The practical aspects of geochemical modeling concentrate mainly on creating geochemical models of the environment and its changes. Geochemical modeling has been recently widely used for describing chemical composition of groundwater as well as factors and processes shaping it. A geochemical model is a tool that allow for understanding hydrogeochemical processes taking place in the environment. It is a basis for further analysis of system`s susceptibility for modifications conducted by human as well as it might be an element of the forecast of the risk of environment contamination. The main advantage of geochemical modeling is simplicity of received data interpretation, possibility of groundwater chemistry origin interpretation, predicting chemistry modifications and also forecasting changes in water quality. Geochemical models can be divided into three main groups: Speciation model – it doesn`t include any information about temporal or spatial distribution of processes, it only describe the effect of water – rock – gases interaction in a single point of hydrogeological space; Reaction path model – it delivers information about succeeding changes of the hydrogeological system (spatial variability) that take place as an effect of providing a load of mass and/or energy. The time effect can be modeled with use of reaction rate constant; Reactive transport model – it include data describing temporal and spatial variability of chemical reactions in the system.

Opis:
An isolated limestone hill (Cisowa Skała), located in the Podhale Basin in southern Poland, has yielded mollusc shells and small vertebrate bones in deposits filling small karst forms such as rock shelters, characteristic molluscan assemblages can be identified, the succession of which reflects changes in the environment and also microhabitat variations depending on local factors, such as slope exposure and type of vegetation. These local factors markedly affect regional environmental trends determined primarily by climate change and, during the last several hundred years, also by human activity. Such malacological analysis enables effective palaeogeographical reconstructions, both on the scale of geographical regions and for microhabitats.

Opis:
This work performed by considering two complementary approaches for investigating the Karst system of Ras El Ma source: (1) The structural approach based on field studies, (2) The functional approach requiring inputs data (precipitations) as well as output data at the exit of the karstic system. The choice of the Ras El Ma source is justified by the fact that it constitutes the main outlet of the Liassic aquifer at the Southwest of Taza town. The structural approach highlighted that the impact of South Rifan and North Middle Atlas faults, oriented mainly NE-SW to ENE-WSW and NW-SE, tectonically linked to the Hercynian and late-Hercynian phases; these faults compartmentalized the karst into panels. The functioning of this karst system is based on the coupling of inputs and outputs, the analysis of interannual hydrograph, flood hydrographs, the recession curves and the analysis of hydrogeochemical results. Respectively, the obtained results are presented as follows: A close relationship between flow rates and precipitation, interannual hydrographs marked by a contrasting variation in flow rates and a periodicity that occurs between low water and high-water years. Concerning flood hydrographs, there are two types, a unit modal hydrographs type which generally occurs following time concentrated rainfall and a second multi modal hydrographs type which follows the repetitive rainfall in the basin. The study of recession curves reveals a clear complexity of the systems supplying the source. However, due to the low drying-off coefficients (7.66∙10-4), the aquifer seems to have a poorly developed drainage network in a flooded area. According to the Mangin method [1975], this karstic system is classified in the category of poor or complex karst systems taking into accounts two parameters (i) and (K), which characterize the functioning of the infiltration zone and the volume of flooded karst, respectively. The physicochemical parameters study highlighted the nature of drained rock by the sources. The correlation between conductivity and different chemical elements shows that bicarbonates and calcium are responsible for the mineralization of the waters of this source. It can be concluded that the low values of mineralization occur during the winter and spring floods. The spring regains its normal mineralization during the summer period.

Opis:
Słowacki Raj to jeden z najpiękniejszych regionów środkowej Europy. Do połowy trzeciorzędu była to lekko pofałdowana równina, z której sterczały niewysokie (do 100 metrów) wapienne pagóry, a rzeka Hornad, płynąca dzisiaj głębokim wąwozem, wiła się między tymi wzgórzami. Wtedy to nastąpiło wypiętrzenie dzisiejszego masywu Słowackiego Raju i jednocześnie zapadanie się kotliny Hornadu. Rzeki i potoki gwałtownie zwiększyły swoje spadki i rozcięły wapienno-dolomitowy masy kilkunastoma głębokimi wąwozami. W ekstremalnie wąskich kanionach utworzyły się na odpornych wapieniach płytowych i skalistych ogromne wodospady oraz niezwykłe skalne formy w postaci baszt, iglic, murów itp. Rzeka Hornad została „uwięziona” w obrębie odpornych skał wapiennych, rozcięła więc podłoże, tworząc niezwykle malowniczy przełom. Wody opadowe łatwo wnikają do wnętrza spękanego masywu, tworząc jeden z największych i najciekawszych systemów jaskiniowych na Słowacji, z jedyną w tej części Europy jaskinią lodową.
The Slovak Paradise is one of the most beautiful regions in Central Europe. Till the mid-Tertiary it was a slightly undulating plain, from which low (up to 100 meters) limestone mounds protruded, and the Hornád river, today flowing in deep gorge, meandered between these hills. At that time the uplift of the presentday massif of the Slovak Paradise and simultaneously the subsidence of the Hornád basin happened. Rivers and streams increased in their gradients violently and cut limestone-dolomite masses by many deep gorges. In extremely narrow canyons huge waterfalls and unusual rocky forms - towers, needles, walls etc. were shaped at resistant platy and massy limestones. The Hornád river was „trapped” within resistant limestone rocks and cut the substratum, forming the unusually picturesque gorge. Precipitation waters easily get in the interior of cracked massif, creating one of the largest and interesting cave systems in Slovakia, with ice cave - the one in this part of Europe.

Opis:
The article describes the nature of the bedrock in areas in the Małopolska Upland where landforms associated with covered karst processes occur. It seeks to find a relationship between geological structure and the potential for covered karst processes to develop. To this end, it includes a review of the literature on the geological structure of three areas in the mesoregions of Wzgór-za Opoczyńskie, Niecka Włoszczowska and Niecka Solecka. Two of the three sites are located in an area of limestone karst, and the third (located in Niecka Solecka) is an area of gypsum karst. All three sites were filled with sediment in the Holocene, but the forms being studied probably formed much earlier. The author also attempts to reconstruct the relief of the Mesozoic surface as digital terrain models. For this purpose, data was taken from geological drillings contained in geological maps of Poland and developed using GIS software. According to digital terrain models in the form of 3D views all three investigated sites are locat-ed in a depressions in the Mesozoic surface (on the slopes or bottom of the basin). That location and low thickness of impervi-ous deposits has caused that migration of underground water, which can affect karstified rocks with increased intensity.

Several isolated teeth and jaw fragments of beavers (Rodentia: Castoridae), discovered at the Villafranchian (MN 16b?) site of Węże 2 in southern Poland, are attributable to two species: Dipoides ex gr. problematicus-sigmodus and Trogontherium (Euroxenomys) minus. The genus Dipoides and the species Trogontherium (Euroxenomys) minus have not previously been reported from Poland. Their presence at the Węże 2 site suggests that these lesser-known and extinct representatives of the Castoridae were adapted to similar conditions as the modern species (Castor fiber and C. canadensis).

Opis:
The crystallization of speleothems can be interrupted by the invasion of allogenic water into cave passages. These interruptions were studied, both in speleothems currently submerged in an underground river and in speleothem sections, which were found at the lowermost fluvially active passage level of the Demänová Cave System. The interaction between speleothems and allogenic water, undersaturated with respect to calcite, is manifested in the presence of siliciclastic material and the corrosion of calcite crystals. The progressive development of corrosion features depends on the duration of the interaction of calcite crystals with allogenic water. Moreover, the movement of the water and siliciclastic deposition over the speleothems can influence the corrosion process. The estimated rate of corrosion, caused by the underground Demänovka River and measured by the weight loss of experimental tablets, is up to 0.029 mm/y. U-series dating indicated that the interaction of speleothems with allogenic water occurred during the Vistulian (Weichselian). The identification of corrosion episodes, caused by allogenic water, is a step towards understanding the origin of hiatuses and establishing criteria for recognition of them.

Opis:
A new locality of coarse-grained cryogenic cave carbonates has been found in the Za Hájovnou Cave in Javoříčko Karst in Central Moravia, Czech Republic. Crystals and crystal aggregates, usually up to 15 mm in size, form typical loose accumulations on the surface of large fallen limestone blocks and clays covering the bottoms of several cave chambers distant from the cave entrance. The cryogenic origin of the carbonates is supported by their mode of occurrence, specific crystal and aggregate morphology, and C and O stable isotope data. U-series dating of one sample of cryogenic carbonate (age 29.5 ±0.1 ka) indicated that a period of karst water freezing occurred in marine isotope stage (MIS) 3, within the Weichselian. The cave also hosts numerous examples of speleothem damage. As shown in this paper, some of these are clearly connected with freezing conditions and cave ice action.

The Moravian Karst in the south-eastern part of the Czech Republic has considerable potential for the development of geotourism. It is characterized by outstanding geodiversity, revealed in abundant, surface and subterranean karst landforms, as well as protracted history of karst evolution which can be traced back to the Mesozoic. An additional value is provided by the presence of cultural heritage, related to exploitation and processing of mineral resources genetically linked to the karst environment. The significance of this area is further enhanced by easy access to karst landforms and phenomena. Five caves, each of different morphology, can be visited. A dense network of educational trails, marked paths, forestry and field-access roads allows the visitor to reach all interesting features of karst morphology.
Kras Morawski w południowo-wschodniej części Republiki Czeskiej jest obszarem o bardzo dużym potencjale geoturystycznym. Cechuje go znaczna georóżnorodność, wyrażająca się bogactwem form krasu powierzchniowego i podziemnego oraz złożoną historią ewolucji krasu, sięgającą ery mezozoicznej. Elementem dodatkowym są liczne obiekty dziedzictwa kulturowego, związane z eksploatacją i przeróbką surowców mineralnych genetycznie związanych ze środowiskiem krasowym. O randze obszaru decyduje także bardzo dobre udostępnienie form rzeźby krasowej. Do zwiedzania jest przystosowanych pięć jaskiń o odmiennej morfologii, wytyczono kilka ścieżek edukacyjnych, a gęsta sieć znakowanych szlaków, dróg leśnych i polnych pozwala na dotarcie do wszystkich interesujących form powierzchniowych.

Opis:
In this study we investigated heavy metals (Cd, Pb, Zn, Cu and Fe) accumulation in upper layer of soils (from three levels: 0-10 cm, 10-20 cm, 20-30 cm) and in the leaves of Pinus syhestris L., Picea abies [L.] Karst., Maianthemum bifolium [L.] F.W. Schmidt and Hedera helix L. collected from nature reserves: Bukowa Kępa, Ostreznik, Zielona Góra, and Slotwina situated south of Poland. The investigations were carried out in 2004-2007. In soil samples from reserves Ostreznik and Slotwina higher concentrations of Cd was noted than -1normal-1 level for protected area (l mg/kg). Elevated Pb content in upper layer of soil were estimated in reserves of Bukowa Kępa (84.9 mg/kg) and Ostreznik (68.9 mg/kg). The level of Pb and Zn in plants leaves was below the values considered as toxic. However the concentration of Cd in leaves of Hedera helia L. collected in nature reserves Bukowa Kępa, Ostreznik and Zielona Góra was higher than the level considered as toxic (5-10 mg/kg d.m.). Relatively low Cu concentration in the leaves of investigated plants indicated poor plant nutrition.
Badano akumulację metali ciężkich (Cd, Pb, Zn, Cu i Fe) w glebie (z głębokości 0-10 cm, 10-20 cm, 20-30 cm) oraz w szpilkach Pinus sylvestris L., Picea abies [L.] Karst, i liściach Maianthemum bifolium [L.] F.W. Schmidt i Hedera helix L. rosnących na terenach wybranych rezerwatów przyrody południowej Polski (Bukowa Kępa, Ostrężnik, Zielona Góra i Słotwina). Materiał do analiz zbierano w okresie wegetacyjnym 2003-2004 (rezerwat Słotwina) oraz 2006-2007 (pozostałe rezerwaty). W próbkach gleby z rezerwatów Ostrężnik i Słotwina odnotowano przekroczenie normy zawartości Cd dla gleb obszarów chronionych (l mg/kg), a z kolei ponadnormatywną zawartość Pb odnotowano w wierzchniej warstwie gleby z rezerwatu Bukowa Kępa (84,9 ug/g) i Ostrężnik (68,9 ug/g). W żadnym z badanych rezerwatów nie stwierdzono przekroczenia fitotoksycznych wartości progowych Pb i Zn. W przypadku Cd w liściach Hedera helix L. z rezerwatów Bukowa Kępa, Ostrężnik i Zielona Góra stwierdzono stężenia mieszczące się w dolnym zakresie wartości uznawanych za fitotoksyczne (5-10 ug/g). Odnotowane w roślinach badanych terenów chronionych stężenia Cu wskazują na niedobór tego pierwiastka i zły stan odżywienia roślin.
