Testing for personality consistency across naturally occurring behavioral contexts in sanctuary chimpanzees ( Pan troglodytes )
Personality is both a reflection of the bio‐behavioral profile of individuals and a summary of how they typically interact with their physical and social world. Personality is usually defined as having distinct behavioral characteristics, which are assumed to be consistent over time and across contexts. Like other mammals, primates have individual differences in personality. Although temporal consistency is sometimes measured in primates, and con…
An Approaching Motor Boat Induces Stress-Related Behaviors in Proboscis Monkeys (Nasalis larvatus) Living in a Riparian Area
Primate ecotourism is a fast-growing tourism sector that may have a negative effect on wildlife. In riparian areas, tourists can conveniently reach primates via motor boats, but no study has directly examined whether such boats cause stress in primates. Our goal was to test whether the approach of a motor boat induces stress-related and other behaviors in proboscis monkeys ( Nasalis larvatus ), an Endangered species. We studied six one-male, mult…
Assessments made easier: Examining the use of a rating-based questionnaire to capture behavioral data in rehabilitant orangutans (Pongo pygmaeus morio)
Rehabilitation and release are commonly used for confiscated, surrendered, and rescued primates. To improve release efficacy it is important to generate accurate behavioral profiles of release candidates. Research on primates traditionally uses observer ratings to measure individual differences. This method is easily implemented, but its validity has been questioned. We evaluated whether observer ratings reflect behavioral data indicating forest …
Filling in the gaps: Acoustic gradation increases in the vocal ontogeny of chimpanzees ( Pan troglodytes )
Human vocal ontogeny is considered to be a process whereby a large repertoire of discrete sounds seemingly emerges from a smaller number of acoustically graded vocalizations. While adult chimpanzee vocal behavior is highly graded, its developmental trajectory is poorly understood. In the present study, we therefore examined the size and structure of the chimpanzee vocal repertoire at different stages of ontogeny. Audio recordings were collected o…
Infrared thermal imaging: Positive and negative emotions modify the skin temperatures of monkey and ape faces
Facial thermography has enabled researchers to noninvasively and continuously measure the changes of a range of emotional states in humans. The present work used this novel technology to study the effect of positive and negative emotions in nonhuman primates by focusing on four facial areas (the peri-orbital area, the nose bridge, the nose tip, and the upper lip). Monkeys and apes were examined for positive emotions (during interactions with toys…
An analysis of bimanual actions in natural feeding of semi‐wild chimpanzees
OBJECTIVE: The objective of the current study was to investigate the lateral dominance for a bimanually coordinated natural feeding behavior in semi-wild chimpanzees. METHODS: Strychnos spp. fruit consumption behaviors in semi-wild chimpanzees as an ecologically comparable feeding behavior to those found in cerebral lateralization studies of non-primate species was investigated. Video recordings of 33 chimpanzees were assessed while they consumed…

Aping expressions? Chimpanzees produce distinct laugh types when responding to laughter of others
Humans have the ability to replicate the emotional expressions of others even when they undergo different emotions. Such distinct responses of expressions, especially positive expressions, play a central role in everyday social communication of humans and may give the responding individuals important advantages in cooperation and communication. The present work examined laughter in chimpanzees to test whether nonhuman primates also use their expr…
Call diversity of wild male orangutans: A phylogenetic approach
Over the past 20 years several studies have attempted to clarify orangutan systematics based on DNA sequences and karyological and morphological data; however, the systematic and phylogenetic relationships among orangutan taxa remain controversial. Surprisingly, few systematic studies have used data from wild‐living orangutans of exactly known provenance. Furthermore, most of these studies pooled data from huge geographic areas in their analyses,…
