Biotopové preference obojživelníků na vybraných lokalitách po těžbě vltavínů / Amphibian habitat preferences in selected localities after mining moldavites.

This thesis pursues amphibian biotop preferences in locations where moldavites were quarried in the past. Field work took place in two localities near Trhové Sviny. The first one is situated near the village of Slavče where an illegal extraction still occures,.The second locality is found by the village of Dobrkovská Lhotka. This locality was partially recultivated in 2010. The aim of this work was to establish which factors do influence different amphibian species in the both studied locations. There were found five various species of amphibians near the village of Slavče: the Common frog (Rana temporaria), the Edible frog (Pelophylax kl. esculentus), the European fire-bellied toad (Bombina bombina), the European tree frog (Hyla arborea) and the Common toad (Bufo bufo). The results were statistically evaluated. Based on them it was established that the Common frog prefers the herb layer, the European Fire-bellied toad prefers semi shaded medium sized pools that do not dry up. The European tree frog and the Edible frog prefer large areas of pools and ponds. More over the edible frog demands ponds that are partially overgrown. The Common toad was represented only with one single individual. Therefore a statistical analasys could not be executed. The whole locality is negatively influenced by local inhabitants who gather here manure and organic waste from their gardens. On locality located near to Dobrkovská Lhotka was transformed from a mining landscape to a pond and three pools. All amphibian species that lived in the locality before reclamation were still present here. Occurrence of Common spadefoot (Pelobates fuscus) was confirmed by the unique finding of a tadpole. Statistical evaluation was not conducted due to the small number and variability of monitored sites.
