Genetic studies of wild common marmoset monkeys (Callithrix jacchus)

As part of an ongoing collaborative link with the University of Reading, and the University of Natal, NE Brazil we are using molecular genetics techniques to investigate the genetic structure of wild populations of marmoset monkeys from two field study areas in Brazil. We are specifically interested in determining genetic variability within and among social groups of these cooperative breeders, parentage (particularly paternity), and gene flow between populations, and correlating this with social behaviour and mate choice to test hypotheses relating to current reproductive skew theory. This study is also important from a conservation point of view as all Callithrichid species are threatened in their natural environment.
