Non-human primates play crucial roles in sustaining natural ecosystems worldwide. However, approximately 68% of primate species are now at risk of extinction, mainly due to agriculture and the depletion of natural resources. Dr Alejandro Estrada at the National Autonomous University of Mexico, Dr Paul A. Garber at the University of Illinois-Urbana, and a group of scientists from various parts of the world recently carried out a study to better understand the role that Indigenous Peoples play in the conservation of threatened primates.
