To start off, here's a short description of what the NPRG is:

The Nocturnal Primate Research Group at Oxford Brookes University specialises on mapping the diversity of the nocturnal prosimian primates of Africa, Asia and Madagascar through multidisciplinary teamwork that includes comparative studies of anatomy, physiology, behaviour, ecology and genetics. Field studies in 16 African countries are helping to determine the origins and distribution of these neglected species, as well as indicating the conservation status of declining forests and woodlands. The combination of biogeographyand emerging techniques of DNA analysis (showing the genetic distance between species) provides a powerful means of reconstructing the origin of the group, its history of spread through Africa and its relationship with allied families. These techniques, including DNA sequencing from museum skins, have been pioneered by the Research Group in collaboration with the Conservation Genetics Unit at the Institute of Zoology, London. 

The NPRG has developed a widespread network of collaborative links with biologists, game wardens, forestry officers, wildlife societies, museums and zoos. It provides a service for the identification and analysis of non invasive specimens (hair samples and tape recorded calls) to help map the biogeography and conservation status of little known primates. Local assistance and training are a vital part of current field studies in Tanzania, Cameroon, Bioko, Gabon and South Africa. The aim has been to work with local people to disseminate scientific information on their natural resources and to inform policy decisions.
