Tailed amphibians (Caudata) in zoos - breeding, rearing, trend analysis
FIALA, Antonín
Amphibians are currently one of the most endangered vertebrate groups. In addition to the well-known factors such as habitat loss, illegal trade or global warming, a rela tively new specific factor is threatening salamanders (Caudata). In recent years, the fungal disease BSAL (Batrachochytrium salamandrivorans) has started to spread not only in Western Europe. The aim of this bachelor thesis is to evaluate the breeding of tailed amphibians in zoos and private breeding, to explore its history and present. The sources are the international database ZIMS, yearbooks of Czech and Slovak zoologi cal gardens and questionnaires distributed among breeders through social networks and in cooperation with AG Urodela. As of the first half of 2023, 801 species of tailed amphibians have been described. Zoos keep 127 species, i.e. 15.9%. According to the findings of my survey, 93 species, i.e. 11.6%, are kept in private breeding.

Breeding of salamanders in zoological gardens - analysis of trends and success
ONDRÁČEK, Michal
Amphibians are currently the most endangered group of verterbrates living on Earth, with populations in the wild declining rapidly due to pollution and loss of their habitat, trapping of individuals from nature, global climate change and spread of diseases. My work is focused on mapping the situation in tailed amphibians in zoos and aquariums all over the world. Using acces to the database of zoos ZIMS creates an overview of all breed species, institutions, which are engaged in their breeding and their results. An integral part of this work is a literary overview of the history of breeding amphibians in zoos, their protection and current ex situ projects.

Keeping and breeding of CITES reptiles in Czech Republic
TRINHOVÁ, Leona
Czech Republic considerably participated on European terraristic history with breeding of many reptiles and amphibians.This thesis covers breeding of reptiles protected on Czech Republic territory by CITES agreement. Based on mapping performed by zoological gardens, other specialized facilities and private breeders, percentage graphs were created for both reptiles not bred in Czech Republic, those bred by terrarists so far without successful reproduction and also for reptiles successfully reproduced. Aim of this thesis was to find outbreeding level of endangered reptiles within Czech Republic.Graphs with breeding success results were created for each genus. It was discovered that the best breeding results exist for reptiles reared most commonly here; turtles are bred less successfully and the least percentage of success was found with crocodiles. Probable reasons for such results were clarified too.
