Střevlík uherský (Carabus hugaricus hungaricus) je druhem dlouhostébelných panonských stepí. Patří mezi zvláště chráněné brouky a je rovněž druhem evropsky významným. V České republice přežívá už pouze na Pouzdřanské stepi a na Pálavě. V článku shrnujeme výsledky výzkumů jeho stanovištních preferencí, demografie a mobility, diskutujeme možnosti jeho ochrany a zároveň se dotýkáme bolestivého tématu ochranářské péče o lokality tohoto druhu., The Carabus hungaricus ground beetle is a highly endangered, dry-grassland specialist listed in the EU Habitats Directive. In the Czech Republic, the beetle survives on the last two sites including the Pouzdřany steppe, and the Pálava hills. Here we report results of extensive mark-recapture studies of this species, including its habitat preference, demography, and dispersal abilities. Furthermore, we discuss the options for its conservation and conservation management of the two inhabited sites., Lukáš Čížek ... [et al.]., and Pokračování čl. na str. CXV kuléru Živy 5/2014
The role of the striatal adenylyl cyclase (AC) and cholinergic systems in the learning and expression of new forepaw movements (reaching with prolonged pushing on a fixed piston) was studied in male Wistar rats. Motor learning processes, prenatal hypoxia, and cholinergic drugs changed the properties of the AC system in the striatum. After learning, the striatal basal AC activity was decreased compared to untrained control rats. In addition, the AC activity was more decreased in animals with a good ability to learn compared to poor learners (up to 31 % and 51 %, correspondingly; p<0.01). Rats subjected to prenatal hypoxia (13-14th days of embryogenesis) had a lower ability to learn the new movements requiring tactile control and the striatal AC activity in these rats was 1.8 times higher (p<0.001) than controls. In vitro application of the cholinergic agonist carbachol (CARB) 10-5 M (corresponding to ~ 0.3 µg), as well as the antagonist scopolomine (SCOP) 10-5 M (~ 0.3 µg) decreased AC activity in the synaptosomal fraction of the striatum. In vivo injections of CARB (0.3-3 µg/1µl) or SCOP (0.3-3 µg/1µl) into the ventral striatum (nucleus accumbens) modified the newly learned sensorimotor skill. After CARB injections the rats performed slower movements with more prolonged pushing. After SCOP the rats could not retain the learned pushing movement. These in vivo and in vitro data suggest that the cholinergic mediator system of the striatum is involved in learning sensory-controlled forepaw movements as well as the regulation of new motor skills by modulating the AC signal transduction process in the striatum. The data confirmed that modification of the striatal AC system resulted in the modulation of reaching behavior and better expression of the learned reflex., I. A. Zhuravin, N. M. Dubrovskaya, S. A.

Cross-border cooperation between Czechs and Germans is currently evolving in numerous areas. In recent years, the mining tradition has become the common denominator of cross-border activities in the Ore Mountains region. The study deals with this aspect of Czech-Saxon cross-border cooperation primarily from the perspective of regional development and tourism. It focuses on the Silver Road and its role in contemporary Czech-Saxon cross-border activities. As a symbol of shared heritage, the Silver Road exemplifies the so-called spatial turn, i.e. the cultural-social dimension of cross-border
cooperation.
The article seeks to present the Silver Road as an example of cross-border cooperation in tourism/destination management and to enrich that cooperation based on a survey of local residents. It strives to determine the importance of the role in public awareness played by this specific tourism product, namely the Silver Road and the mining heritage as a whole, what Czechs and Saxons know about this local tradition and the neighbouring country’s traditions. It is concluded by summarizing the potentials and deficits of the Silver Road’s destination management.
The study presents the results of a questionnaire survey implemented in mid-2016 which focused on the mining theme and its potential for Czech-Saxon cross-border activities and cooperation. The survey targeted local residents in communities along the Silver Road. 350 questionnaires were collected in the Czech Republic and 550 in Saxony. Quota sampling was applied, with minor deviations in terms of age and distribution of the population in the Czech sample due to the Silver Road’s small geographical coverage. Since the stakeholders on both sides of the border are planning to include these sites in the list of UNESCO World Heritage Sites, we need to study the attitudes of local residents to determine whether this is
lived heritage.
The article demonstrates that the mining theme plays an important role in the practice of cross-border cooperation between the Czech Republic and the Free State of Saxony. A cross-border activity with such high ambitions as UNESCO listing cannot be found elsewhere in the Czech borderland. While the Saxon side exhibits a considerably higher intensity of cross-border activities, Ore Mountains residents in both countries are little aware of the ways the mining heritage is being developed in the neighbouring country. Most of the respondents do not know the neighbouring country’s mining
heritage sites. Based on this finding, we argue that cross-border marketing communication needs to be improved, and this applies both to the Saxon institutions dealing with regional development and tourism and to entities at the level of the Karlovy Vary and Ústí nad Labem regions. Moreover, CzechTourism, as the key agency of central government responsible for marketing communication and destination management in the Czech Republic, should probably get involved in these activities as well. Finally, cross-border destination management needs to be encouraged. Bilingual activities should perhaps be undertaken because the language barrier continues to pose a relatively major obstacle to Czech-Saxon cross-border
cooperation, a fact also revealed by previous studies. In addition to these promotional activities, marketing communication needs to be elaborated more comprehensively to better tap the possibilities of new media. Inspiration can be drawn from similar activities or areas with cross-border destination management.
