The material of Machichnus regularis and Machichnus multilineatus was re-examined with respect to the potential tracemaker. New characters were defined for M. multilineatus – scratch profile with flat horizontal bottom and undulated microrelief of scratches. Based on these characters and additional information, both previously suggested tracemakers (beavers and porcupines) are rejected and a new one – a large squirrel is proposed. The squirrel origin of gnawing traces is additionally supported by actuopalaeontologic study on gnawing behaviour of recent red squirrels. On this basis, squirrels are recognized as overlooked but important taphonomic agents in Late Cenozoic assemblages. The tracemaker of M. regularis was not unambiguously recognized, but a connection with smaller squirrel or aplodontid species seems probable.

Summary Trichodorus similis associated with potato in the Czech Republic was described and illustrated. This study provides additional information on morphometrical and morphological characters of T. similis and integrates morphological and genetic data obtained by species-specific polymerase chain reaction and sequencing (ITS1 and D2-D3 expansion segments of 28S rDNA). The knowledge on morphological variability and genetic diversity is extended, and a rapid and accurate molecular diagnostics was successfully applied.

Geographic Data

Digital aerial images (DAI) include position, elevation and also spectral information (visible bands and near-infrared band) about the captured area. The aim of this paper is to present the possibilities of automatic analysis of DAI for updating of the Fundamental Base of Geographic Data of the Czech Republic with a focus on buildings. Regular updates of buildings (automatic detection of new and demolished buildings) are based on the analysis of coloured point clouds created by an automatic image matching technique from each time period. The created approach compares point clouds from different time periods to each other. The advantage of this solution is that it is independent of the manner of keeping the buildings in the database. It does not matter whether the buildings in the database have correct positions and their footprints correspond to the roof shapes or external walls. The involved method is robust because a digital surface model generated by image matching techniques can contain numerous errors. Shaded areas and objects with blurred textures are problematic for automatic image correlation algorithms and lead to false results. For this reason, derived layers containing additional information are used. Shadow masks (layers with modelled shadows) are used for the verification of indications and to filter out errors in the shaded areas using a contextual evaluation. Furthermore, additional information about the road and railway networks and morphological operations of opening and closing were used to achieve more accurate results. All these information sources are then evaluated using decision logic, which uses the generally applicable rules that are available for different datasets without the need for modification. The method was tested on different datasets with various types of buildings (villages, suburbs and city centres) which cover more than 20 square kilometres. The developed solution leads to very promising results without the need of acquiring new data.

Moravian Karst

The atlas The Moravian Karst and its Environs includes an area which is used for outdoor activities by a number of schools not only from the Czech Republic, of all types and grades. The needs of fieldwork in the frame of teacher education at PdF MU were taken into consideration. The mission of the Atlas is to raise the desire to learn something new about processes which shaped and still shape the landscape of the Moravian Karst and its environs. The Atlas itself is composed of two parts. The first part is formed of thematically oriented maps with a scale of 1 : 160,000 and 1 : 400,000. It contains an overall overview of the chosen area and a description of its basic natural and cultural characteristics. The second part comprises detailed maps with a 1 : 20,000 scale which contain a huge amount of additional information. Its main goal is to support its users in their exploration of areas they choose from maps and thus help them to explore points of interest which are depicted by cartographic symbols.

AbstractThe earliest world record of the green lizards, Lacerta viridis group, is described from the lower Miocene of Central Europe. The fossils come from greenish, calcareous marls and limnic clayey silts of the Ottnangian zone MN 4 of the Dolnice locality near Cheb in the Czech Republic. Sediments are interpreted as marginal, riparian facies. The material consists of isolated frontal bones of two different ontogenetic stages and one isolated fragment of parietal. Their morphology is identical to that of the extant members of the L. viridis group. However, the fossil material is much older than the previously described specimens of green lizards. Therefore, this finding extends our knowledge about the evolution and stratigraphic range of the group and about composition of the early Miocene herpetofauna in central Europe.
