Ekologicko-faunistická charakteristika měkkýšů (Mollusca) Hončovy hůrky

Abstract

Purpose of this Bachelor thesis is realisation of malakozoological survey and ecological-faunistic evaluation of recorded data from Hončova hůrka hill in Skotnice near Příbor. Hončova Hůrka hill is importatnt mineralogical location and it’s soil structure is formed by těšinit rocks asociation. Initialy it were discovered due to small quary and then because of gravel mining it were enlarged to present status. Quarries generaly show many different types of sites. Těšinit rocks involved high content of calcium which is important factor for molluscs live. Researched location were devided to three sampling areas, where hand-operated salvage were done and which represent heterogenity of local conditions. Most of molluscs species are normally occurring and least concern species (IUCN 2001). In location were found five species which are ranks among near threatened species (IUCN 2001) – there are water species Anisus leucostoma and four land species Ena montana, Vertigo pygmaea, Daudebardia rufa and Pupilla muscorum.
