One new genus and seven new species of Phoridae (Diptera) are described from Bialowieska Forest in Poland, namely Poloniphora Disney & Durska gen, n. with the species P. bialoviensis Disney sp. n., Megaselia henrydisneyi Durska sp. n., M. joannae Disney sp. n., M. marekdurskii Disney sp. n., M. teresamajewskae Disney sp. n.: M. trojani Disney sp. n., Phora michali Disney sp. n., The new genus shows affinity with Australasian genera, Beckerina Malloch and Eocene fossils erroneously assigned to Megaselia in the past.
Secondary deformations are ground movements occurring in areas of ceased underground mining. These are associated with delayed readjustment of rock mass resulting in subsidence, discontinuous deformations (sinks, cracks, etc.) due to destruction of underground, usually shallow, workings, and elevation of ground surface in response of rock mass to rising groundwater levels following the end of mine water drainage. Comparative analysis of secondary deformations in two former mining areas in the first period after cessation of underground hard coal mining is the subject of this study. We used ERS-1/2 and Envisat satellite radar interferometry data processed with PSInSAR technique and GIS to map vertical (in satellite’s line of sight, LOS) movements of the surface and analyse them in relation to location of coal fields and underground water table rise. In the study, two areas have been compared, the Ostrava city in the Czech part of the Upper Silesian Basin and the Wałbrzych Coal Basin in Poland. The results of analyses based on the results of PSInSAR processing between 1995 and 2000 for the Wałbrzych site indicate uplift (up to +12 mm/year) in closed parts of coal fields and subsidence (up to -8 mm/year) in areas of declining mining. Results of PSInSAR analysis over the Ostrava site indicate decaying subsidence after mine closures in the rate of up to -6 mm/year during 1995-2000. Residual subsidence and gentle uplift have been partly identified at surroundings of closed mines in Ostrava from 2003-2010 Envisat data. In Wałbrzych gentle elevation has been determined from 2002 to 2009 in areas previously subsiding. and Blachowski Jan, Jiránková Eva, Lazecký Milan, Kadlečík Pavel, Milczarek Wojciech.
In late Medieval Poland, and by analogy in all of Europe, luxury at the royal table was represented by the use of imported choice products that were accessible only to a selected few. Similar to jewels, valuable robes or articles of precious metals, these products were kept in the royal treasury. In addition to the obvious culinary impact (however limited it may have been) and alleged healing powers of certain spices, the choice products most certainly played their part in issues of prestige and propaganda. The use of luxury products can be considered as an interesting indicator of change, particularly with respect to relations among the estates in late Medieval Poland. The presence of such products at the table or in the diet was the very article that distinguished the royal court from other courts of the late Medieval Polish kingdom; at the same time, it brought them closer to contemporary courts of the rulers of west Europe. and Agnieszka Januszek-Sieradzka.
This article analyses the processes of creating the township on the example of Borne Sulinowo, one of the youngest cities in Poland. The collapse of the communism in the Centre and Eastern Europe caused, that Poland had made efforts for the revitalization of areas occupied by Soviet armies. Borne Sulinowo, a small city located in the north-western Poland, suffered the same fate as desolation of its areas after the departure of the Soviet Army and anew settlement by the civil settlers. Issues brought up in the article are focusing on problems of the adaptation of the settlers to the new cultural environment, on shaping local bonds and on the degree of the identification with the new place of residence.
Chromosome numbers are given for 16 taxa (and one interspecific hybrid) of Hieracium subgen. Pilosella originating from Central Europe: H. apatelium Nägeli et Peter (2n = 45), H. aurantiacum L. (2n = 36), H. bauhini Besser (2n = 36, 45, 54), H. brachiatum Bertol. ex DC. (2n = 45, 48, 63, 72), H. densiflorum Tausch (2n = 36), H. echioides Lumn. (2n = 18, 27, 36), H. floribundum Wimm. et Grab. (2n = 36, 45), H. glomeratum Froel. (2n = 36, 45), H. guthnickianum Hegetschw. (2n = 54), H. lactucella Wallr. (2n = 18), H. onegense (Norrl.) Norrl. (2n = 18), H. pilosella L. (2n = 36, 45, 54), H. piloselliflorum Nägeli et Peter (2n = 36, 45), H. piloselloides Vill. (2n = 36), H. rothianum Wallr. (2n = 36), H. schultesii F. W. Schultz (2n = 45), and the hybrid H. floribundum × H. aurantiacum (2n = 36). New chromosome numbers are reported for H. brachiatum and H. floribundum. The octoploid cytotype (2n = 72), recorded in H. brachiatum, is the highest ploidy level ever found in plants from the subgen. Pilosella originating from the field. Aneuploidy, rare in this subgenus in Europe, occurs in this hybridogenous species as well: it was recorded in one plant (2n = 48) collected in a hybrid swarm H. pilosella × H. bauhini. The breeding system in H. bauhini, H. brachiatum, H. densiflorum, H. echioides, H. pilosella, H. piloselloides, and H. rothianum was studied. The sexual reproduction of pentaploid H. pilosella is a new observation: it means an increase of diversity in possible reproduction modes of those cytotypes having odd chromosome numbers.
Chromosome numbers (ploidy levels) were recorded in the following 25 taxa of Hieracium subgen. Pilosella: H. arvicola Nägeli et Peter (2n = 45), H. aurantiacum L. (2n = 36, 45), H. bauhini Besser (2n = 36, 45), H. bifurcum M. Bieb. (2n = 45), H. brachiatum Bertol. ex DC. (2n = 36, 45), H. caespitosum Dumort. (2n = 36), H. cymosum L. (2n ~ 4x), H. densiflorum Tausch (2n = 36, ~ 4x), H. echioides Lumn. (2n = 18, 45), H. fallacinum F. W. Schultz (2n = 36, 45), H. floribundum Wimm. et Grab. (2n = 36, ~ 4x, 45,), H. glomeratum Froel. in DC. (2n = 45), H. iseranum Uechtr. (2n = 36), H. kalksburgense Wiesb. (2n ~ 5x), H. lactucella Wallr. (2n = 18), H. macranthum (Ten.) Ten. (2n = 18), H. onegense (Norrl.) Norrl. (2n = 18), H. pilosella L. (2n = 36, 45, 54), H. piloselliflorum Nägeli et Peter (2n = 45), H. pilosellinum F. W. Schultz (2n = 36, 45), H. piloselloides Vill.

Schultz (2n = 36, 45, ~ 5x), H. zizianum Tausch (2n = 27, 36, 54), and one hybrid, H. onegense × H. pilosella (2n = 36). Besides chromosome counts in root-tip meristems, flow cytometry was used to determine the DNA ploidy level in 83 samples of 9 species. The presence of a long marker chromosome was confirmed in tetraploid H. caespitosum and H. iseranum, in pentaploid H. glomeratum, and in both tetraploid and pentaploid H. floribundum. The documented mode of reproduction is sexual (H. densiflorum, H. echioides, H. piloselloides) and apomictic (H. brachiatum, H. floribundum, H. pilosellinum, H. piloselloides, H. rothianum, H. zizianum). Hieracium bifurcum and H. pistoriense are sterile. The chromosome number and/or mode of reproduction of H. bifurcum (almost sterile pentaploid), H. pilosellinum (apomictic pentaploid), H. piloselloides (apomictic triploid), H. pistoriense (sterile triploid), H. rothianum (apomictic triploid) and H. zizianum (apomictic triploid) are presented here for the first time. The sexual reproduction recorded in the pentaploid H. echioides is the second recorded case of this mode of reproduction in a pentaploid cytotype of Hieracium subgenus Pilosella. A previously unknown occurrence of H. pistoriense (H. macranthum – H. bauhini) in Slovakia is reported.
Autorovi jsou vlastní přístupy „nové filmové historie“, které oprošťují psaní o filmu od tradičních kategorií a periodizací a obracejí badatelskou pozornost k ekonomickým aspektům filmového průmyslu nebo k problematice distribučních mechanismů a diváctví. To obnáší interdisciplinární přesahy a nutnost pracovat s velice rozmanitým materiálem. Autor podnikl rozsáhlý průzkum v archivech šesti zemí a jeho výsledky kriticky a organicky propojuje s poznatky z dalších zdrojů včetně svědectví pamětníků. První část metodologicky vzorně koncipované publikace je věnována kulturním transferům v rámci severního trojúhelníku, s dalšími zeměmi sovětského bloku i s kapitalistickými státy. Ve druhé části autor v kontextu stalinismu a následného „tání“ mapuje úlohu filmové distribuce, s jejíž pomocí se režim snažil o sociální integraci občanů. Mimořádně přínosná je podle recenzentky třetí část, věnovaná divácké recepci filmů a podepřená lokální případovou studií o chování a postojích publika v poválečném Brně, Lipsku a Poznani., The author of the book under review uses the approaches of the "new film history", which frees him from writing about film using traditional categories and periodizations, and allows him to turn his attention to economic aspects of the film industry or to distribution mechanisms and audiences. That approach entails overlaps with other disciplines and work with a wide range of material, The author has undertaken extensive research in the archives of six countries, and has critically and organically linked this research together with information from other sources, including eyewitness accounts. The first part of this methodologically exemplary publication is devoted to cultural transfers in the "Northern Triangle" (Czechoslovakia, East Germany, and Poland) with other Soviet bloc countries and also with capitalist states. In the second part, in the context of Stalinism and the subsequent Thaw the author looks at the role of film distribution which the régime sought use to integrate its citizens into society. An exceptional contribution of the publication, according to the reviewer, is the third part, which focuses on film-audience reception, supported by local case studies on the behaviour and attitudes of Brno, Leipzig and Poznan audiences after the Second World War., [autor recenze] Alena Šlingerová., and Obsahuje bibliografii a bibliografické odkazy
The development of knowledge on geodynamic processes is one of the most important issues in the Earth’s science. Over decades, geodetic techniques have been applied to study the geodynamics. The Global Navigation Satellite Systems (GNSS) have been reliably used for monitoring geodynamic processes. The satellite gravimetric missions such as GRACE (Gravity Recovery And Climate Experiment) and GRACE Follow-On (GRACE-FO) missions have provided numerous valuable information concerning temporal mass variations within the Earth system which can subsequently be converted to surface deformations of the Earth. The main aim of this study is to compare vertical deformations of the Earth's surface over the area of SouthEastern Poland obtained from GNSS data with the corresponding ones determined from GRACE data. The GNSS data for the period between 2008 and 2013 from 25 permanent GNSS stations operating in South-Eastern Poland and the latest release of GRACE-based Global Geopotential Models (GGMs) were used. GNSS data and GRACE-based GGMs were processed with the GAMIT/GLOBK and the IGiK‒TVGMF (Institute of Geodesy and Cartography - Temporal Variations of Gravity/Mass Functionals) packages, respectively. The results obtained indicate that monthly vertical deformations of the Earth’s surface determined using GNSS data are generally in a good agreement with the corresponding ones obtained from GRACE satellite mission data. Coefficients of correlation between these vertical deformations range from 0.60 to 0.90 and standard deviations of their differences are in the range of 2.6 - 5.7 mm., Walyeldeen Godah, Malgorzata Szelachowska, Jagat Dwipendra Ray and Jan Krynski., and Obsahuje bibliografii
We analysed the polymorphism of cross-amplified microsatellite loci in two endangered butterflies of the genus Phengaris, which inhabit warm grasslands. Specimens of P. arion and P. 'rebeli' collected in Poland showed contrasting levels of variability in the investigated loci. All six tested microsatellites were highly variable in P. arion, whereas in P. 'rebeli' one locus was monomorphic and the other four loci showed a rather low level of polymorphism. Genetic differentiation was small or moderate among P. arion populations and high among P. 'rebeli' populations. We hypothesise that these differences reflect: (1) the relatively high genetic variability of P. arion compared with other members of the genus, indicated by previous studies on allozymes; (2) the small, in the majority of cases, genetic differentiation among populations of P. arion, which suggests recent gene flow; (3) a decrease in the genetic variability and increased isolation of peripheral populations of P. 'rebeli'. In both species, the occurrence of "null" alleles was suggested for some loci, which should be taken into consideration in future studies of the population structure. Additional analysis performed on the corrected frequency of alleles indicated that "null" alleles constitute only a minor problem when estimating genetic differentiation, using FST and AMOVA, however they strongly influence estimates of heterozygosity and FIS, and inferences about the number of genetic groups and assignment of individuals, especially in the case of 'P. rebeli'.
During a study 20 hydrophilid beetle species and 2,457 individuals of beetles belonging to 4 genera: Cercyon, Cryptopleurum, Megasternum and Sphaeridium were collected. On the surface of the bodies of 59 beetles (2.40% of the beetles collected) belonging to six species, 174 cases of phoresy [55 deutonymphs of Uropoda orbicularis (Müller, 1776) and 119 pedicels without deutonymphs] were observed. New hydrophilid beetle carriers of phoretic deutonymphs of U. orbicularis are given. Most mites were carried by Sphaeridium species. The population dynamics of both groups of arthropods was also studied. Most cases of phoresy were recorded in May and in the second half of July. However, phoretic deutonymphs were not present on the body surface of hydrophilid beetles throughout the whole period of this study.
