Our findings underscore the critical conservation value of this KBA and call for urgent landscape-level interventions to mitigate hunting pressure and maintain habitat integrity.

Notably, over 40% of primate encounters were polyspecific groups with up to five species. Interestingly, primate encounter rates and assemblages in this unprotected landscape were similar to observations in protected areas within the same ecoregion.

From January to December 2019, we surveyed over 1,500 km of reconnaissance walks and sighted over 1,120 primate groups belonging to seven IUCN Threatened and one Near-Threatened species, including chimpanzees Pan troglodytes ellioti.

In this study published in the journal Primates, we assess the persistence and polyspecific assemblages of diurnal primates across the unprotected Ebo–Ndokbou–Makombe landscape, Cameroon, designated the Yabassi Key Biodiversity Area, one of the largest remaining forest tracts in the Gulf of Guinea

Exactement. These associations between primate species are often said to be an antipredation strategy: dilution of predation pressure and "more capacities" to detect predators (including humans)

Yes, and in this context, I'm also investigating the association between different species of primates within the same group.
