    The Cretaceous biostratigraphy of the James Ross Island region is generally based on palynomorphs and macrofossils (bivalves, ammonites). During geological mapping of the northern James Ross Island a number of samples from Upper Cretaceous lithologies were gathered to test the presence of foraminifers as a possible tool for stratigraphic evaluation of Upper Cretaceous strata. Limited number of samples did not provide foraminiferal content large enough to give relevant information for biostratigraphic conclusions. Samples from older sediments of Whisky Bay and Kotick Point formations (Albian – Turonian) were either not fossiliferous or contained scarce specimens of agglutinated foraminifers. Foraminiferal assemblages from younger sediments of Hidden Lake and Santa Marta formations (Coniacian – Campanian) contained species with both agglutinated and calcareous types of tests. Many of studied marine sediments were barren of foraminifers, probably due to late diagenetic secondary decalcification. Taxonomy of low-diversified assemblages was carried out and a biostratigraphical and palaeobiogeographical significance discussed

    Almost black shale filling fissures in the Štramberk Limestone belonging to the Silesian Unit, Outer Western Carpathians contain prolific and poorly to moderately well preserved spores, pollen, organic-walled dinoflagellate cysts, foraminifers, and calcareous nannofossils. A detailed micropaleontological analysis of the proved stratigraphical interval from the Valanginian to the Albian indicated sedimentary conditions of brackish, restricted marine, shallow-marine and neritic sedimentation. Moreover, it drew attention to occasional influence from the Boreal province in the depositional area of the NW part of Tethys, especially during the Early Valanginian and Hauterivian, as supported by the presence of highlatitude nannofossils and organic-walled dinoflagellate cysts. Terrestrial miospores form a significant component of palynoassemblages and give evidence of continent proximity in the Valanginian-Barremian interval. Samples were acquired from isolated fissure fills in the Štramberk Limestone and, therefore, they do not represent a continuous section.Web of Science62433230

    Consumer Behavior When Buying Local Food

    The aim of this bachelor thesis is to identify the main consumer purchasing preferences of regional foods in the region Capital City of Prague and Central Bohemia. Methodology of the theoretical background is primarily in analysis, synthesis and compilation of secondary data from the available literature, legislation, information SZIF, MZe ČR, ČSÚ and the other relevant institutions. The methodology own work is based on a questionnaire survey using personal interviews. A questionnaire survey was conducted from October to November 2015 in Prague and Central Bohemia. The investigation showed that the two regions are not significant differences. Consumers in the purchase of local foods behave in the Central Bohemia approximately the same as in Prague

    The project based on behavioural tests of 7 week old German Shepherd puppies performed in police kennel in Prackovice nad Labem and Domažlice. The project focused on verification of the usability and improvement of the selection of puppies using behavioural test. We tested the possibility of environmental effect (presence of shooting range near the kennel Domažlice) on the later success of puppies in the behavioural test. The aim of the project was collecting additional data which were use to improve and verify procedure for early selection of puppies. We checked the possibility of habituation breeding females and their puppies to noise, including monitoring of the different environments in the kennels in. It was found that different results are affected by of their mothers. This means that puppies raised by mothers from the police kennel near shooting range are better evaluated later in the disciplines of evaluating response to noise compared with pups from mothers of police kennel without shooting range. Worse response to noise had pups from litters with a higher number of pups. Reviews summarizing the literature on heritability of behavioural traits in dogs have been published repeatedly over the last four decades. The conclusions of these reviews vary to some extent. We applied meta-analysis and re-evaluated the literature available collecting 47 references dealing with heritability of behavioural traits in domestic dogs. For each study included, data was extracted for individual behavioural traits. Each of these traits was entered into the analysis as a separate unit of measure, giving a total of 1761 measures. We classified the traits measured in each study into five functional categories (Environment, Herding, Hunting, Play, and Psychical characteristic). The metaanalysis has shown low general heritability of the categorised behavioural traits analysed. Thus, the commonly used behaviour tests for many breeds, to determine the dog's eligibility for reproducing, traditionally required by many associations, is not supported by the present results of the meta-analysis

    Microfossils of the Albian and Cenomanian shales from the Stramberk area (Silesian Unit, Outer Western Carpathians, Czech Republic)

    Microbiostratigraphic study of sporomorphs, dinoflagellate cysts, foraminifers and calcareous nannofossils documented the age and paleoenvironmental features of black and grey-green, organic-rich sediments in the classical area of Stramberk (Baska Formation, Silesian Unit, Outer Western Carpathians). Age-assessments suggest Late Albian and Cenomanian age (foraminiferal Zones Rotalipora appenninica, R. reicheli and R. cushmani; nannoplankton Zones BC27/UC0-UC4). The character of dinoflagellate cyst assemblages (e.g. presence Pterodinium) reflects open-sea environment. The presence of calcareous foraminifers and nannofossils gives an evidence of depositional conditions above the carbonate compensation depth (CCD). The presence of some terrestrial and non-marine aquatic palynomorphs (e.g. Tetraporina, Lecaniella) documents the proximity of a continent and fluvio-lacustrine influences. The presence of microfossils tolerating low-oxygen bottom conditions such as foraminifers of genus Lingulogavelinella and jaws of polychateous annelids (scolecodonts) reflect a dysaerobic bottom environment. Co-occurrence of Boreal and Tethyan species encountered in foraminiferal and palynomorph assemblages documents the influences from the higher latitudes on the depositional area of northern Tethys. Moreover, Lower-?Middle Cenomanian sporomorphs (angiosperms) have similar character to others of the same age from the Blansko Graben, in the SE part of the Bohemian Cretaceous Basin, which is situated on the SE border of the West European plate
