KUS, Lukáš
This bachelor thessis treats with the ontogenesis of bobby-soxers of Bufo bufo (L.). The informations about the global crisis of amphibians, their rapid decrease of species diversity and the fact of importance of arteficial reproduction as the last possibility of species preservation, brought me to this work. I have made observation of ontogenesis of bobby-soxers Bufo bufo from the gamete to the metamorphosed frog, to be able to state the best conditions for their transformations, due to their possible survivance for future.
Incidence and conditions of the existence of amphibians and reptiles
KUS, Lukáš
Thesis deals with the mapping of our species of amphibians and reptiles in the hills of St. Thomas and the right bank of Lipno. Findings of older data in the atlas and the lack of extension work to monitor the biodiversity of species inspired me to map the location. Alignment of the square with the border position was more than 40 years, closed intensive human activities. This reasoning was that the richness and diversity of amphibians and reptiles could be acknowledge. The aim was to monitor the designated area and to identify the occurrence of individual species of amphibians and reptiles. Locate their habitats in which they propose to Match and protect this natural heritage for the future.
