Chimpanzee (Pan troglodytes schweinfurthii) grouping patterns in an open and dry savanna landscape, Issa Valley, western Tanzania

Camille Giuliano et al.

Summary: Fission-fusion societies, characterized by flexible social organization, have been studied in chimpanzees as a referential model for understanding human social evolution. This study investigated chimpanzee grouping patterns in the Issa Valley of western Tanzania and found that party size was influenced by seasonal food availability, the presence of swollen females, and the risk of predation in open vegetation. The study fills a knowledge gap in understanding chimpanzee sociality and provides insights into the social behavior of early hominins.

All-You-Can-Eat: Influence of Proximity to Maize Gardens on the Wild Diet and the Forest Activities of the Sebitoli Chimpanzee Community in Kibale National Park

Chloe Couturier et al.

Summary: Understanding the impact of agricultural expansion on primate populations is crucial for conservation efforts. This study investigated the behavior and diet of wild chimpanzees in Uganda in relation to the availability of maize, a domestic resource. The results showed that the presence of maize had little effect on the activity and diet of the chimpanzees, as they continued to exploit wild fruits and play a role in seed dispersal and forest regeneration. This suggests that although agricultural expansion poses threats to primate habitats, they are still able to adapt and maintain their ecological functions.

Surviving at the extreme: Chimpanzee ranging is not restricted in a deforested human-dominated landscape in Uganda

Matthew R. McLennan et al.

Summary: Research on chimpanzees in the Wagaisa community in Uganda, a landscape characterized by high human population density, deforestation, and agricultural development, showed that chimpanzees are able to range extensively in the human-dominated landscape without evidence of limited ranging. They used areas around small forest patches and eucalyptus plantations as core habitat areas. This suggests that conservation efforts for chimpanzees in such transformed habitats may not conflict with regional sustainable development.

Intercommunity interactions and killings in central chimpanzees (Pan troglodytes troglodytes) from Loango National Park, Gabon

Laura Martinez-Inigo et al.

Summary: The study focused on intercommunity interactions of individuals in a community of central chimpanzees living in Loango National Park in Gabon. It revealed that males were the main participants in territorial patrols and intercommunity aggressions, while females also played important roles in intergroup interactions.
