Linking behaviour and physiology of female bonobos (Pan paniscus)
The present study investigates sexual behaviour and the importance of dominance in female bonobos. Detailed behavioural studies were carried out on four mixed-sex captive bonobo groups; morphological data and faecal samples were collected to allow non-invasive assessment of physiological …

Differences in the Communicative Behavior and Neurobiology of Chimpanzees (Pan troglodytes) and Bonobos (Pan paniscus)
<p>Chimpanzees and bonobos have distinctly different vocalizations, but it is unclear why these differences have evolved. We hypothesized that differences in habitat and feeding ecology have selected for bonobos to have an increased reliance on vocal communication compared to chimpanzees. To …

An Empirical and Theoretical Comparison of the Socio-ecological Behaviors of Captive Chimpanzees (Pan troglodytes), Bonobos (Pan paniscus), and Western Lowland Gorillas (Gorilla gorilla): Social Tolerance and Behavioral Responses to Changes in Food Quality and Distribution
<p>Chimpanzees and gorillas are sympatric in most of their range in Central Africa, however, bonobos do not overlap with either of the other two species. This difference has been hypothesized to be the main factor leading to the socio-ecological traits of each species. Access to, and competition …

Stopy jako ukazatele vlastností homininů a anatomicky moderních lidí
… otisky nohou anatomicky moderního člověka a šimpanze Bonobo (Pan paniscus) a shrnujeme jejich charakteristické rysy, které využíváme při určování původců fosilních stop. Sledujeme vztah mezi anatomií nohy, především přítomností či absencí klenby nožní, způsobem lokomoce a výsledným tvarem stopy. …

Comparisons of the socio-behavioral differences between chimpanzees (Pan troglodytes) and bonobos (Pan paniscus), investigating the impact of a naturally occurring polymorphic microsatellite deletion in the 5’ flanking region of arginine vasopressin receptor 1a (AVPR1a) on gene expression and sociality within the Pan genus
<p>Among the great apes, chimpanzees are unique in having a polymorphic deletion of a ~350bp microsatellite containing region (DupB) in the 5’ flanking region of the arginine vasopressin receptor 1a (AVPR1a) gene. This results in three genotypes (DupB+/+, DupB+/- and DupB-/-) of AVPR1a in …

Yakety sacs: laryngeal air sac usage in great apes
… recordings to determine when bonobos (<em>Pan paniscus</em>) inflate their laryngeal air sacs. We identified a region of interest in the air sac area and quantified it using frame-by frame image analysis. We then compared the difference in areas between resting, swallowing, and vocalizing …

Communication and Travel Coordination in Wild Bonobos
… and travel patterns of wild bonobos (Pan paniscus), a species of great ape with a highly fluid ‘fission-fusion’ social structure, in which individuals from a single social group regularly divide into smaller subgroups (‘parties’). In Chapters 1 and 2, we investigate the long-distance …

Evidence of Language Prerequisites in Pan: Orofacial-Motor and Breath Control in Chimpanzees and Bonobos
… However, here we describe both skills in genus Pan, which contains our closest extant relatives: chimpanzees (Pan troglodytes) and bonobos (Pan paniscus). We hypothesized that OFM and BC would be present in both species of Pan and that bonobos would demonstrate increased OFM and BC due to their …

Reconstructing Soft Tissues of Plio-Pleistocene Hominids using Comparative Anatomy of Modern Humans & Great Apes
… the facial soft tissue thicknesses for Chimpanzees (Pan troglodytes), Bonobos (Pan paniscus), and by extension other Pliocene hominids, such as Australopithecus africanus, are presented. In addition, new methods for predicting nasal protrusions for all African great apes, modern humans, and …

Chromosomes and spermatozoa of the great apes and man
… species phylogenetically related to man, the chimpanzee (Pan troglodytes), the pygmy chimpanzee (Pan paniscus), the gorilla (Gorilla gorilla), and the orangutan (Pongo pygmaeus) have been analysed with chromosome banding techniques and compared to the human chromosome comple¬ ment. This has shown …

The role of modularity and integration in shaping primate pelvic girdle evolution
… primates (Gorilla beringei, Hylobates lar, Pan paniscus and Macaca mulatta). The reduction of inherent human constraint is paired with elevated levels of disparity, indicative of inherent high levels of evolvability present within the human pelvis. Particularly of interest is the low …

Pictorial Primates: A Search for Iconic Abilities in Great Apes
Pictures and other iconic media are used extensively in psychological experiments on nonhuman primate perception, categorisation, etc. They are also used in everyday interaction with primates, and as pure entertainment. But in what ways do primates understand iconic artefacts? What implications do …
