The occurrence and biotope preferences of amphibians in former military area near České Budějovice.

Submitted bachelor thesis deals with biotope preferences of amphibians. Experimental part of my work was carried out at former military tank ground near České Budějovice from March until June 2010. Biotope preferences were examined at these species: European Fire-bellied Toad, European tree frog, Agile Frog and Common toad. Since the end of military activity in 1990, there has been growing ecological succession which influences each of the species. The aim of my work was to find out what factors have influence on particular species and compare the outcomes with those of previous works carried out between 1995 and 2008. The observation was pursued during the daytime, above all at night, when frogs are most active. The outcomes has been statistically evaluated and it was found out that great pond surfaces are the most suitable for European tree frog and Common toad, whereas European Fire-bellied Toad and Agile Frog do not mind gradual growth of vegetation, moreover it suits them. The data from 1995 indicate appearance of European tree frog also in pools. My outcomes from 2010 confirmed their appearance only in ponds. On the contrary, Agile Frog has been seen here recently only seldom, in 2010 together with European Fire-bellied Toad it was the most common species. Common toad was the most precious species in the examined habitat. It was found only a few specimens. Appearance of Common toad was registered in ponds in 1995 but this was not confirmed in 2010
