其他摘要：This study deals w ith the research on molluscs of the neovolcanic mountains Ostr..ky in Centra l Slovakia, where only few data were recorded so far. The large areas of the mountain s were deforested and converted to ag ricultural land with grasslands and fields. In remai ns of forest s w it h or ig inal woods as beech, maple and especially in niva of brooks were refuges of the malacocenoses with typical Car pat hia n element s (Bielzia coerulans, Faustina faustina, Mac rogastra lat estriata, M . tumida, Monachoides vicinus, Vestia turgida, Vitrea transsylvanic a). The occurrence of the Nat ura 2000 annex species Vertigo moulinsiana and V. angustior proves the genuine character of the local swamps. Another abundant population of the annex species Unio crassus albensis is known from the river Tisovn¨ª k. There were identified 87 s pecies of molluscs till now, of which 14 species are lis ted in the Red list of Slovak threatened species (EN ¨C Vert igo moulinsiana, VU ¨C Deroceras rodnae, Gyraulus laevis, Pisidium pseudosphaerium, Unio crassus albensis, Vertigo subst riata, V. angustior, NT ¨C Daudebardia brevipes, Euconulus praticola, Macrogastra tumida, M. latestriata, Oxyloma elegans, Vert igo antivertigo, Vitrea t ranssylvanica).
