Funkce čištění srsti v kontextu sexuálního chování
GREGOROVÁ, Vendula
The main aim of this study was to investigate whether males and females of Barbary macaques (Macaca sylvanus) use social grooming as a commodity on the biological market. More specifically, it is focused on the exchange of grooming and mating opportunities. I have analyzed the exchange on three different levels: i) the long-term exchange, ii) short-term exchange of grooming for subsequent mating opportunity and iii) short-term patterns between grooming and mating, including assessment of rates of pre- and postsexual grooming. The results demonstrate that primates can trade grooming for sex and it seems that they do it on long-term rather than on immediate basis. Such relationship between grooming and mating might support the importance of long-term relationships between males and females. The result of the study also show that females groom males more often after the sexual activity, however males grooming was not affected by context (pre-, post-, non sexual).

The main aim of this thesis was to summarize published literature about olfaction and its role mainly in social interactions. Firts, I described the anatomy of the sense of smell and production of chemical stimuli. In the second part I discussed available literature on the use of chemical signals in the social behavior and reproduction.
