The effects of infant births on male–female relationships in Cebus capucinus

American Journal of Primatology, 2009
AbstractMost primates are characterized by cohesive male–female bonds that are maintained year round. While recent studies have addressed the selective pressures influencing the evolution of male–female relationships in primates, we know relatively little about the proximate mechanisms affecting them.

The ecological role of the prehensile tail in white-faced capuchins (Cebus capucinus)

American Journal of Physical Anthropology, 1999
Prehensile tails appear to have evolved at least twice in platyrrhine evolution. In the atelines, the tail is relatively long and possesses a bare area on the distal part of its ventral surface that is covered with der-matoglyphs and richly innervated with Meissner's corpuscles.

The effects of observer presence on the behavior of Cebus capucinus in Costa Rica

American Journal of Primatology, 2007
AbstractWe report on the responses of Cebus capucinus in the Santa Rosa Sector of the Area de Conservación Guanacaste, Costa Rica, to the presence of observers over a 4‐week period. Study groups were habituated to different degrees: (1) Cerco de Piedra (CP): continuous observations began in 1984; (2) Exclosure (EX): focus of an 18‐month study on males ...

Vigilance in white-faced capuchins, Cebus capucinus, in Costa Rica

Animal Behaviour, 1995
Abstract Vigilance behaviour was examined in four groups of white-faced capuchins in Santa Rosa National Park, Costa Rica. In each group, males spent more time vigilant than females. Average time spent vigilant within each group was not significantly correlated with group size, but was negatively correlated with the number of male group members.

Life history and locomotion in Cebus capucinus and Alouatta palliata

American Journal of Physical Anthropology, 2009
AbstractAs an individual matures from birth to adulthood, many factors may influence the positional repertoire. The biological and behavioral changes that accompany a growing individual are expected to influence foraging strategy, social status and interaction, diet, predator avoidance strategies, and ultimately positional behavior as a behavioral link

Predictors of Parasitism in Wild White-Faced Capuchins (Cebus capucinus)

International Journal of Primatology, 2013
Parasite infections in wildlife are influenced by many factors including host demography, behavior and physiology, climate, habitat characteristics, and parasite biology and ecology. White-faced capuchins (Cebus capucinus) host a suite of gastrointestinal and pulmonary parasites, yet the mechanisms affecting host susceptibility and parasite ...

Locomotor and postural behavior in Alouatta palliata and Cebus capucinus

American Journal of Primatology, 1992
AbstractPositional behavior of two platyrrhine monkeys, Alouatta palliata and Cebus capucinus, was observed at La Pacifica and Santa Rosa National Park, Costa Rica. Frequency data for locomotion, postures, support diameters, orientation of supports, and use of canopy were recorded on focal males and females.

Intergroup encounters in wild white-faced capuchins (Cebus capucinus)

International Journal of Primatology, 1996
Wrangham (1980) hypothesized that knowledge of the nature of intergroup encounters is crucial to understanding primate social relationships and social organization. I studied a single social group of wild white-faced capuchins over a period of 26 months and observed 44 encounters between social groups during 3703 hr of observation.

Capuchin Monkeys (Cebus capucinus) and the Ancient Maya

Ancient Mesoamerica, 1992
AbstractTwo genera of nonhuman primates that include howler monkeys (Alouatta palliata and Alouatta pigra) and spider monkeys (Ateles geoffroyi) currently are located throughout the Maya region. It has been suggested that the Classic Maya associated these monkeys, especially howler monkeys, with the arts.

Alpha Male Capuchins (Cebus capucinus imitator) as Keystone Individuals

2018
A keystone individual is defined as an individual that has a disproportionate impact on group dynamics relative to its representation in the population. Here we use over 30 years of behavioural, physiological, paternity, and demographic data collected on the Santa Rosa, Costa Rica, capuchin population to address the question of whether or not alpha ...
