Breeding and rearing of lizards (Varanidae, Teiidae) in zoos - analysis of distribution and trends
 JURÁŇOVÁ, Adéla
This bachelor thesis deals with the census and comparison of bred and reared varanid and tejovid species in zoos around the world. The aim of the thesis is to record and compare the numbers of reared hatchlings, kept species and numbers of individuals with their threat level and origin of occurrence. The ZIMS database was used to map all individuals and species, and the IUCN Red List was used to assess the degree of endangerment and CITES category was determined by Species+. It was found that zoos kept mostly non-native and least concern species rather than endangered species. The exceptions were Australia, with the highest number of individuals and species of native varanids kept, and South America keeping native teiid species. Australia has not bred nor kept any tejovids and has fallen far behind North America and Europe, which have bred the most species of both varanids and tejovids. Species bred in zoos fell mainly into the category of species of least concern, with endangered varanid species bred mostly in Europe, where a critically endangered species also bred, and to a lesser extent in North America and Europe. Breeding teiid species were found only in Europe and North America and were only species of low concern.
