Heterospecific social behavior in primates: Insights into the evolutionary roots of pet-keeping
Primate interspecific interactions with both other primates and non-primate species range from predator–prey dynamics to affiliative behaviors such as grooming, play, and carrying. While many primates participate in interspecific associations or commensal relationships, to our knowledge interspecific social interactions have never been systematically synthesized. Here, we present the first comprehensive review of such interactions, compiling 427 …
Pseudoreplication in Primate Communication Research: 10 Years On
Pseudoreplication is the statistical error of collecting numerous datapoints from a single unit (such as an individual), which are not independent, and applying statistical methods that assume independence of data. Importantly, pseudoreplication increases the chances of Type 1 errors (i.e., false positives), bringing findings and conclusions based on pseudoreplicated analyses into question. Ten years ago, Waller et al. (2013) published a paper hi…
The face is central to primate multicomponent signals
A wealth of experimental and observational evidence suggests that faces have become increasingly important in the communication system of primates over evolutionary time and that both the static and moveable aspects of faces convey considerable information. Therefore, whenever there is a visual component to any multicomponent signal the face is potentially relevant. However, the role of the face is not always considered in primate multicomponent …
Personality Traits Predict Social Network Size in Older Adults
Humans live in unusually large groups, where relationships are thought to be maintained through complex socio-communicative abilities. The size and quality of social networks are associated with health and well-being outcomes throughout life. However, how some individuals manage to form larger social networks is not well understood. If socio-communicative traits evolved to form and maintain relationships, personality traits should be associated w…
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…
Ten Years of Positive Impact of a Conservation Education Program on Children's Knowledge and Behaviour Toward Crested Macaques (Macaca nigra) in the Greater Tangkoko Area, North Sulawesi, Indonesia
In areas where primates are threatened, environmental education interventions are a key way to increase the local population’s knowledge of their environment and encourage positive attitudes and habits to preserve the environment and wildlife on a local and global scale. This study assesses the impact of Tangkoko Conservation Education (TCE), the Macaca Nigra Project’s conservation education programme, running since 2011 in North Sulawesi for sch…
Macaca nigra in the Spotlight: Accounting for Diversity in Behavior, Ecology, and Conservation in Primates
Investigating the Relationship Between Sociality and Reproductive Success in Wild Female Crested Macaques, Macaca nigra
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 …
Revisiting Darwin's comparisons between human and non-human primate facial signals
Darwin and other pioneering scholars made comparisons between human facial signals and those of non-human primates, suggesting that they share evolutionary history. We now have tools available (the Facial Action Coding System) to make these comparisons anatomically based and standardised, as well as analytical methods to facilitate comparative studies. Here we review the evidence establishing a shared anatomical basis between the facial behaviour…
Morphological variants of silent bared‐teeth displays have different social interaction outcomes in crested macaques ( Macaca nigra )
OBJECTIVES: While it has been demonstrated that even subtle variation in human facial expressions can lead to significant changes in the meaning and function of expressions, relatively few studies have examined primate facial expressions using similarly objective and rigorous analysis. Construction of primate facial expression repertoires may, therefore, be oversimplified, with expressions often arbitrarily pooled and/or split into subjective pig…
Social Tolerance in Wild Female Crested Macaques ( Macaca nigra) in Tangkoko‐Batuangus Nature Reserve, Sulawesi, Indonesia
In primates, females typically drive the evolution of the social system and present a wide diversity of social structures. To understand this diversity, it is necessary to document the consistency and/or flexibility of female social structures across and within species, contexts, and environments. Macaques ( Macaca sp.) are an ideal taxon for such comparative study, showing both consistency and variation in their social relations. Their social st…
Multicomponent and Multimodal Lipsmacking in Crested Macaques ( Macaca nigra )
Primates’ communicative signals are often dynamic and composed of multiple components, sometimes belonging to different sensory modalities. Such multicomponent signals are of crucial importance in the study of communication: the addition of extra features to a signal has the potential to modulate or change the meaning and message of the specific signal. Traditionally, however, components of compound signals are studied in isolation from each othe…
