Medúzka sladkovodní (Craspedacusta sowerbii) je jediným zástupcem rosolovitého zooplanktonu v našich vodách. Článek popisuje historii zkoumání, životní cyklus a ekologii tohoto u nás nepůvodního druhu, který byl do celého světa zavlečen z Číny., The Freshwater Jellyfish (Craspedacusta sowerbii) is the only representative of gelatinous zooplankton in Czech waters. This article describes the body of research on the invasive species, which has spread from China all over the world. The article also includes a description of the species´ life cycle and ecology., and Adam Petrusek.
Detailed knowledge of the circumstances behind the extermination of particular animal species is a key premise for their eventual return, reintroduction and ongoing preservation. Data on the presence of the Brown Bear (Ursus arctos) in the Czech landscape are usually limited to simple entries about the day and place where the last specimens in particular (usually mountainous) regions were slain. Demand for more precise data, especially regarding the last documented presence of bear cubs, has emerged in respect of the recently discovered ability of bears to migrate over long distances. The newly collected data allowed the author to present amuch more complete historical view of the process of extermination of the Brown Bear in the Czech territory. and Jan Andreska.
The prolonged survival of the Brown Bear (Ursus arctos) population in the Bohemian Forest was largely possible due to the protec tion of this animal, which was considered a rare and desirable trophy. Consequently the bear was able to survive in the Bohemian Forest for a hundred years longer than in the Ore Mountains. Isolated populations in the Sudetes survived in Moravia, and the last specimens were hunted down in the 1740s. Bears hunted down during the 19th century in the Beskydy Mts. can almost certainly be considered casual migrants from the Slovak part of this mountain range. The return of bears to the territory of Moravia and Silesia corresponds with the consolidation of the Slovak population due to the protection introduced in 1932. and Jan Andreska.
In this article the author attempts to evaluate and conceptualise how the law and legal institutions function during the period of post-communist transformation in Slovak society, taking into consideration the fact that there are other social processes in addition to transformation that contribute to the challenges that the law is faced with. To begin the author introduces the topic's theoretical and methodological background, followed by a discussion of the legal code and its developmental trends, with a focus on the causes and impact of changes. The author also analyses the particular functions and dysfunctions of the law within the broader social context, in an effort to highlight those areas where the law and legal institutions do not function sufficiently and may contribute to the establishment of a dysfunctional, anti-legal culture.
