With its hormone assay services, the endocrinology laboratory supports a large number of scientific projects on the biology and conservation of primates and a few other mammal species.

With our work we assist extensively the research of several scientific units within our institute, but also provide support for external projects as part of international collaborations. The projects are mainly conducted in the fields of behavioural endocrinology, behavioural ecology, reproductive biology, field endocrinology, conservation and animal welfare.   

Amongst those, the endocrinology laboratory is also involved in 7 projects of the Research Group "Sociality and Health in Primates" (FOR 2136) funded by the German Research Foundation (DFG) since July 2014.
