Plži Obory Hvězda, Petřína a Vyšehradu v Praze [Gastropods of the Hvězda Game Reserve, Petřín and Vyšehrad in Prague]

Anotace: Mollusc fauna of three protected areas in the capital of the Czech Republic, Prague, was revised after 25 years (Hvězda Game Reserve, Petřín) or studied for the first time (Vyšehrad). In total, 56 molluscs species were found and the survival of endangered species Vertigo angustior and Nesovitrea petronella in the Hvězda Game Reserve was verified. Generally, some sensitive species in well-preserved localities are being replaced by weed species, including non-indigenous ones such as the invasive Arion vulgaris, and the southern element Monacha cartusiana. On the other hand, some woodland species such as Arianta arbustorum, Urticicola umbrosus, Eucobresia diaphana, Arion silvaticus and Lehmannia marginata apparently spread in Prague.
