The paper compares ranging and territoriality among African apes, finding that economic defendability does not fully explain interspecific variation in territorial behavior.

This study shows nonhuman primates use supra-regular recursive grammars in vocal sequences, challenging the idea that syntax is unique to humans.

This study uses non-invasive fecal samples and chromosome 21 target capture sequencing to analyze bonobo population structure, identifying three subpopulations and river barriers influencing genetic differentiation.

The paper quantitatively describes the vocal repertoire of wild bonobos using machine learning to classify 11 acoustically distinct call types from over 1500 calls.

This study compares the developmental patterns of bonobo and chimpanzee infants in the wild, finding similar trajectories but species-specific differences in travel and proximity behaviors.
