Within the context of affiliative interactions among primates, social play is one of the most commonly observed behaviors. Specifically, social play allows younger individuals such as infants and juveniles to learn social roles and help in furthering their social development. Here, we examine social play and behavioral sequences among a wild eastern chimpanzee community (Pan […]
A08: Non-maternal Adult- And Subadult-Infant Interactions in Wild Woolly Monkeys
BackgroundIn many primates, males and/or non-lactating females are attracted to young infants and some may provide nonparental care (alloparenting) or engage in other forms of infant handling (holding, carrying, playing, and inspecting). The way in which these interactions play out may differ depending on varied factors (e.g. relatedness to the infant, dominance relationships, group dynamics, […]
B60: Vocal Communication and Group Decision Making in Lowland Woolly Monkeys (Lagothrix lagotricha poeppigii)
In group living species, animals must form a consensus about when and where to perform daily activities (e.g., traveling, foraging, resting) in order to maintain cohesion, otherwise the benefits of group living will be lost. Here, we use behavioral, geospatial, and vocal data of wild lowland woolley monkeys (Lagothrix lagotricha poeppigii) to examine what role […]
C22: The Social Network of Hamadryas Baboons: Observing a Group of Captive Baboons at Prospect Park Zoo
Hamadryas baboons (Papio hamadryas) live in multilevel societies characterized by a hierarchy of nested one male units (OMUs), in which leader males and adult females form strong social bonds. Such strong bonds are thought to be the result of males constantly observing and maintaining close contact with the females in his unit to prevent her […]
B01-P: Intra- and Inter-Individual Variation in the Vocalizations of Lowland Woolly Monkeys (Lagothrix lagotricha poeppigii) From the Tiputini Biodiversity Station, Ecuador
Primates, characterized by high degrees of fission-fusion dynamics, often use vocalizations to coordinate travel, locate and maintain contact with groupmates, recruit new party members, regulate spatial cohesion, and avoid extra-group conspecifics. In environments with limited visibility, individually distinct vocalizations may become increasingly important as they decrease listener uncertainty and allow individuals to differentially respond to […]
C35: The functionality of vocal communication in lowland woolly monkeys (Lagothrix lagotricha poeppigii) from the Tiputini Biodiversity Station, Ecuador
In group-living primates, vocal communication is critical for social interactions, maintaining contact with group members, avoiding confrontations with individuals in other groups, and evading predators. For this study, we investigated the vocalization patterns of wild woolly monkeys from the Tiputini Biodiversity Station in Amazonian Ecuador. We combined behavioral data previously collected in 2014 and 2015 […]
B61: Temporal Variation of Long Calls In New World Monkeys (Ateles belzebuth, Lagothrix lagotricha poeppeigii, Plecturocebus (Callicebus) Discolor, and Alouatta seniculus)
This Biological Anthropology research was focused on the differential use of temporal long calls within four New World Monkey species (Ateles belzebuth, Lagothrix lagotricha poeppeiggi, Plecturocebus (Callicebus) discolor, and Alouatta seniculus) in the Amazon rainforest of Ecuador. This study analyzes the differences between species’ long calls to expand the information on why and more importantly […]
