Tailed amphibians (Caudata) in zoos - breeding, rearing, trend analysis

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
