Investigating the impact of a long-term research and conservation project on the expansion of land use and land cover in a remote area of central DRC

Trees, Forests and People, 2023
Anthropogenic impact and population growth have caused a dramatic loss of biodiversity worldwide. Deforestation due to logging, mining, and burning are of particular severity in tropical rainforests with the Amazonian and Congolese basins harboring the ...

Comparison of induced neurons reveals slower structural and functional maturation in humans than in apes

eLife, 2021
We generated induced excitatory neurons (iNeurons, iNs) from chimpanzee, bonobo, and human stem cells by expressing the transcription factor neurogenin-2 (NGN2).

Salivary Cortisol Reaction Norms in Zoo-Housed Great Apes: Diurnal Slopes and Intercepts as Indicators of Stress Response Quality

Animals, 2022
Monitoring changes in cortisol levels is a widespread tool for measuring individuals’ stress responses. However, an acute increase in cortisol levels does not necessarily denote an individual in distress, as increases in cortisol can be elicited by all ...

Cell-Mediated Immune Ontogeny Is Affected by Sex but Not Environmental Context in a Long-Lived Primate Species

Frontiers in Ecology and Evolution, 2021
Ecoimmunology conceptualizes the role of immunity in shaping life history in a natural context. Within ecoimmunology, macroimmunology is a framework that explains the effects of habitat and spatial differences on variation in immune phenotypes across ...

Implicit Measures Help Demonstrate the Value of Conservation Education in the Democratic Republic of the Congo

Frontiers in Psychology, 2020
Biodiversity is being lost at unprecedented rates. Limited conservation resources must be prioritized strategically to maximize impact. Here we introduce novel methods to assess a small-scale conservation education program in the Democratic Republic of ...

Bonobo and chimpanzee gestures overlap extensively in meaning. [PDF]

PLoS Biology, 2018
Cross-species comparison of great ape gesturing has so far been limited to the physical form of gestures in the repertoire, without questioning whether gestures share the same meanings.

Targeted helping and cooperation in zoo-living chimpanzees and bonobos [PDF]

Royal Society Open Science, 2021
Directly comparing the prosocial behaviour of our two closest living relatives, bonobos and chimpanzees, is essential to deepening our understanding of the evolution of human prosociality.

Behavioural diversity of bonobo prey preference as a potential cultural trait

eLife, 2020
The importance of cultural processes to behavioural diversity in our closest living relatives is central to revealing the evolutionary origins of human culture. However, the bonobo is often overlooked as a candidate model.

Evaluating Self-Directed Behaviours and Their Association with Emotional Arousal across Two Cognitive Tasks in Bonobos (Pan paniscus)

Animals, 2022
Self-directed behaviours (SDBs) are widely used as markers of emotional arousal in primates, and are commonly linked to negative arousal, or are used as indicators of stress or poor welfare. However, recent studies suggest that not all SDBs have the same

Nest grouping patterns of bonobos (Pan paniscus) in relation to fruit availability in a forest-savannah mosaic.

PLoS ONE, 2014
A topic of major interest in socio-ecology is the comparison of chimpanzees and bonobos' grouping patterns. Numerous studies have highlighted the impact of social and environmental factors on the different evolution in group cohesion seen in these sister
