The cooperative sex: Sexual interactions among female bonobos are linked to increases in oxytocin, proximity and coalitions

Journal Article

In some species habitual same-sex sexual behavior co-occurs with high levels of intra-sexual alliance formation, suggesting that these behaviors may be linked. We tested for such a link by comparing behavioral and physiological outcomes of sex with...

The evolution of intergroup tolerance in nonhuman primates and humans

Journal Article

Males with a mother living in their group have higher paternity success in bonobos but not chimpanzees

Journal Article

Aggression by male bonobos against immature individuals does not fit with predictions of infanticide

Journal Article

Information transfer efficiency differs in wild chimpanzees and bonobos, but not social cognition

Journal Article

Several theories have been generated to understand the socio-cognitive mechanisms underlying the unique cooperative abilities of humans. The ‘interdependence hypothesis' posits first, that the cognitive dimension of human cooperation evolved in contexts...

Beyond the group: how food, mates, and group size influence intergroup encounters in wild bonobos

Journal Article

In social-living animals, interactions between groups are frequently agonistic, but they can also be tolerant and even cooperative. Intergroup tolerance and cooperation are regarded as a crucial step in the formation of highly structured multilevel...

Metabarcoding of eukaryotic parasite communities describes diverse parasite assemblages spanning the primate phylogeny

Journal Article

Abstract Despite their ubiquity, in most cases little is known about the impact of eukaryotic parasites on their mammalian hosts. Comparative approaches provide a powerful method to investigate the impact of parasites on host ecology and evolution, though...

Behavioural diversity of bonobo prey preference as a potential cultural trait

Journal Article

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. Further, a prominent critique to...

Novelty Response of Wild African Apes to Camera Traps

Journal Article

Summary Temperament and personality research in humans and nonhuman animals measures behavioral variation in individual, population, or species-specific traits with implications for survival and fitness, such as social status, foraging, and mating success...

Male reproductive skew is higher in bonobos than chimpanzees

Journal Article

Summary The two closest living relatives of humans, bonobos (Pan paniscus) and chimpanzees (Pan troglodytes), share many traits that are common in humans but rare in other mammals, including societies with high fission–fusion dynamics, male philopatry...

Sex-specific association patterns in bonobos and chimpanzees reflect species differences in cooperation

Journal Article

In several group-living species, individuals' social preferences are thought to be influenced by cooperation. For some societies with fission–fusion dynamics, sex-specific association patterns reflect sex differences in cooperation in within- and between...

Stable and fluctuating social preferences and implications for cooperation among female bonobos at LuiKotale, Salonga National Park, DRC

Journal Article

Abstract Objectives Female bonobos (Pan paniscus) are characterized as highly affiliative and cooperative, but few studies have quantified the strength and stability of female intra-sexual relationships or explored how variation in social relationships...
