Osobnost u primátů: metody hodnocení, mezidruhová porovnání a reprodukční úspěch
MÁSÍLKOVÁ, Michaela
This thesis is focused on the stable individual behavioural tendencies, i.e. personality, in non-human primates. The studies included in the thesis address questions related to the methods of personality assessment and evolutionary bases of personality. The personality structures in three callitrichid species in captivity, including common marmosets (Callithrix jacchus), cotton-top tamarins (Saguinus oedipus), and golden-handed tamarins (Saguinus midas), were investigated using common behaviour coding and trait rating. More specifically, the minimum length of observation necessary to describe the personality structure, the similarities and differences between personality structures of two related tamarin and one more distantly related marmoset species, and the links between personality and reproductive success, were investigated.

Zhodnocení vlivu socioekologických rozdílů na osobnostní rysy u drápkatých opic
PEJCHOVÁ, Tamara
This work focuses on socio-ecological differences among genera of Callitrichidae and its influence on the personality traits of these primates. The main output of this work is a database build upon available literature, showing in which features do the genera differ the most (home range and the number of offsprings per year) and on the other hand what features where common for most genera (way of obtaining food and the size of the litter).

Callitrichidae - trade, captive breeding, distribution pattern
FOLEJTAROVÁ, Lucie
This work is focused on working with available information about biology, about conditions of population in free nature, about endanger and protection (mainly CITES, IUCN) of tribe called Callitrichidae. Then it valuates and elaborates the international trade based on information from the database CITIES during the years 1977 2013. Results are rated in case of business reasons, origin of specimen, structure of commodities, lands of import and export. Among the critical endagered species belong Leontopithecus caissara (Black-faced Lion Tamarin) with the estimated population in free nature of just only 400 pieces, Saguinus oedipus (Cotton-headed Tamarin) with the population in free nature about 6000 pieces. Trade with Common Marmoset (Callithrix jacchus), which is classified as not endangered, makes 81% of the trade. Mostly reasons of this trade are commerce, science, zoo and medical reasons since 1990s. Most of these pieces come from breeding in captivity and they are mostly samples and then living pieces. The biggest importers are USA and Switzerland. The biggest exporters are Germany and Great Britain. South Afrika is the biggest exporter of living pieces and Germany and Great Britain are the biggest exporters of samples.
