TL;DR: The combined observational and genetic evidence suggest an intercommunity attack on an adult male chimpanzee at a new research site in Loango National Park, Gabon, adding to the growing evidence that intercommunity killings are a rare but widespread phenomenon among chimpanzees and not an artifact of human provisioning or habituation.

TL;DR: An agent‐based model was developed to simulate the growth rate, age structure, and social system of the endangered mountain gorillas in the Virunga Volcanoes region, and provided a better basis for further studies on the complex relationships among individual life history events, group composition, population ageructure, and growth rate patterns.

TL;DR: Among 19 adult male gorillas monitored for up to 12.5 years, it was found that all three phenotypic traits were positively correlated with the average number of mates per male, but only crest size and gluteal muscle size were significantly correlated with offspring survival and the annual rate of siring offspring that survive to weaning age.

TL;DR: In this article, the effect of seismic oil exploration on large mammal distribution in an 80 km2 area of Loango National Park, Gabon was explored and the authors concluded that low-impact seismic operations can cause considerable temporary habitat loss for species with large ranges and suggest that the impact on those endangered species can be minimized by adequately spacing seismic lines and activity in space and time to enable species to move away from the progressive noise disruption.

TL;DR: Results of this study show that subordinate males may gain reproductive benefits even while queuing for dominance status, consistent with the proposal that the outcome of group fission in primates is not only influenced by maternal relationships among individuals, but also by patrilineal relationships.
