Current research

The social systems in many primates are characterized by strong bonds among related females. The close relationship between mothers and their infants is particularly distinctive and of large importance for the infants survival. In contrast, little is known whether fathers also have an impact on the infants’ survival. Most female primates mate with multiple males during likely conception which requires genetic analysis to determine paternity in these species. Since we now have the tools to study the relationship between fathers and offspring, my study aims at investigating whether male rhesus macaques (Macaca mulatta) develop distinctive relations towards infants. This project is focusing on three parts: (i) the ontogeny of male-infant relationship, (ii) the mechanism/s underlying these relationships (paternal care and/or mating effort), (iii) the effects of male care on the infants’ fitness. My study combines 7 years of behavioural data (starting from birth of the infants), morphometric data as well as paternity analysis.
I collected field data at the Caribbean Primate Research Center (CPRC) of the University of Puerto Rico (UPR), USA.

This project was funded by the Konsul Karl und Dr. Gabriele Sandmann-Stiftung (KKGS) and by the Elsa-Neumann-Stipendium (ehemals NaFöG) of the Humboldt-University of Berlin as well as the Deutsche Akademische Auslandsdienst (DAAD) and partly by the Research Academy of Leipzig (RAL) and the Deutsche Forschungsgesellschaft (DFG).
