Science + Research

Bonobos were the last great apes to be studied in the wild — and there's still so much we have to learn! Groundbreaking research is underway to discover more about bonobos. Local field teams have done outstanding work to habituate groups of bonobos to human presence, allowing scientists to observe them more closely.

At Kokolopori, a long-term research program led by Martin Surbeck of Harvard University is shedding light on fascinating aspects of bonobo behavior. They are making discoveries on everything from intergroup cooperation to the influence of female alliances, and much more. The research program works in concert with local field teams and provides opportunities for aspiring Congolese scientists.

Beyond bonobos, the first-ever field observations of the rare Salongo Monkey (Cercopithecus dryas) were made at Kokolopori. BCI and Vie Sauvage have conducted a preliminary study—and we seek to renew the effort!

Vie Sauvage founder and president, Albert Lotana Lokasola recently earned his Ph.D. in herpetology at the University of Kisangani. He has initiated CongoHerp Lab, an exciting new study of reptiles, amphibians, and avian fauna at Kokolopori. Providing hands-on, practical opportunities for students and local participants, this program is making strides to learn more about important indicator species.

BCI also collaborates with the DRC Ministry of Scientific Research and the Max Planck Institute to conduct surveys and build the capacity of Congolese personnel. We provide training in biodiversity survey, participatory mapping, and bonobo monitoring techniques. The more we know about bonobos, the more we know how to help them.
