Primates exhibit diverse social structures, yet how proximity reflects social relationships may depend on the spatial threshold applied. This study examined within-group social relationships in red-tailed monkeys (Cercopithecus ascanius) in...

The growing field of comparative thanatology aims to shed light on how and why the understanding of death evolved. Observations across different nonhuman primate species have reported care-taking behaviour toward dead infants, but also cann...

Primates constitute an integral part of many African ecosystems. In some areas, primate species can be locally very abundant, while in others they are rare or absent. Our central question is: does the abundance of primate bones (or carcasse...
