Abiotic and biotic conditions in the cave Chýnov and their protection.
LUTZ, Vojtěch
In my thesis I worked cave water chemistry and invertebrate sampling Chýnov cave. Sampling took place three times from June 2007 to April 2008. Sampling sites regularly distributed in the cave and differed intensity, distance from the surface and assumed the character of the overburden. These values were measured: sodium, potassium, calcium, nitrites, nitrates, phosphates, sulfates, chlorides, ammonium ions, water hardness. In the end I tried to summarize the results from samples of patterns and compare them with results from the years 2006, 2007. In comparison with the samplesbeing from 2006, 2007, the apparent increased calcium content and the reduction of nitrate. The collection of invertebrates at a site such as Chýnov cave (protected by law č.114/1992 sb. On nature and lands cape), the need for the exemption granted by the Government of the Republic through the Ministry of Environment. For this reason Ireferred to the research results of the first invertebrate cave Chýnov of 16 May 2000, conducted by Dvorak and Mlejnek masters. Research includes only the basic data. We have found three kinds of snails, two species of caddis, four species of beetles from the family of ground beetles, three species of butterflies, one species of spider and twospecies of crustaceans.
