Animal Conservation, EarlyView.This study highlights the importance of the unprotected Yabassi Key Biodiversity Area, Cameroon, for primate conservation in the Gulf of Guinea biodiversity hotspot. We modelled primate distribution patterns and found that historically overlooked parts of the landscape have high species richness and are critical for some threatened species.

Innovative social behavior in chimpanzees (Pan troglodytes)
American Journal of Primatology, 2007 AbstractWe present evidence of agonistic buffering in captive chimpanzees, recorded from 1993 until 2005, mainly from ad libitum sampling in over 2000 hr of observation. A total of 33 agonistic buffering episodes were analyzed for context and effects of this complex social behavior.

Trace Element Patterns in Juvenile Wild Chimpanzee Dentitions
Archaeometry, EarlyView.ABSTRACT Trace elements are used to infer mammalian early‐life diets, environmental toxins, dispersal patterns, stress histories, and weaning ages. Here, we employ laser ablation‐inductively coupled plasma‐mass spectrometry (LA‐ICP‐MS) to reveal elemental patterns in our closest living relatives, chimpanzees.

Dogs (Canis familiaris), but not chimpanzees (Pan troglodytes), understand imperative pointing.
PLoS ONE, 2012 Chimpanzees routinely follow the gaze of humans to outside targets. However, in most studies using object choice they fail to use communicative gestures (e.g. pointing) to find hidden food.

Comprehension of functional support by enculturated chimpanzees Pan troglodytes
Current Zoology, 2011 Studies of causal understanding of tool relationships in captive chimpanzees have yielded disparate findings, particularly those reported by Povinelli & colleagues (2000) for tool tasks by laboratory chimpanzees.
