Faunistika není mrtvý obor zoologie. V prvním dílu diskutujeme záludnosti faunistiky a rozdíly mezi faunistikou a sběratelstvím. Měkkýši byli vybráni jako modelová skupina organismů, na nichž ukazujeme historii vývoje oboru v Českých zemích a vývoj měkkýší faunistiky., Faunistics is not a dead subject of zoology. The challenges of faunistics and the difference between faunistics and collecting are discussed. Molluscs were chosen as a model group to show the history of the subject in the Czech Republic and the development of mollusc faunistics., and Vojen Ložek, Lucie Juřičková.
Large amounts of abandoned limestone quarries in the Bohemian Karst provide a great opportunity to study different stages of spontaneous succession simulta - neously. Molluscs are a suitable model group for this study –many land snail species including the rare ones occur in these quarries. Because of the large variability of habitats, quarries abandoned for around 60 years have higher species diversity. and Alena Kocurková, Lucie Juřičková.
In 2008, a call to map out the Cartusian Snail’s (Monacha cartusiana) recent distribution in the Czech Republic was published (Živa 2008, 2: 73). Due to the useful help of experts and the general public, the intensive spread of this non-indigenous species was observed and described. In this short report, we discuss inter alia the changes in distribution of several non-native land snails species. and Alena Peltanová, Lucie Juřičková.
The importance of stream corridors and flood deposits for the spreading of molluscs is demonstrated using some examples from the Czech territory. Three types of floodplain debris, which contain shell accumulation, are distinguished: allochtonous debris accumulated by river flow on riversides, autochtonous accumulation in quiet parts of alluvium far from the main flow, and accumulation caused by strong turbulence during flooding. and Vojen Ložek, Lucie Juřičková.
