Bimanual Coordination and Right-Hand Bias in Extractive Foraging by Wild Sapajus libidinosus. [PDF]

Am J Primatol
Wild Sapajus libidinosus exhibit a significant preference at the population level for using their right‐hand fingers to extract nut kernels when employing bimanual coordination. ABSTRACT Bimanual coordination is considered a crucial factor in the evolution of manual lateralization.

Oxytocin and social gaze during a dominance categorization task in tufted capuchin monkeys

Frontiers in Psychology, 2022
Visual attention to facial features is an important way that group-living primate species gain knowledge about others. However, where this attention is focused on the face is influenced by contextual and social features, and emerging evidence in Pan ...

Cyto-, myelo- and chemoarchitecture of the prefrontal cortex of the Cebus monkey

BMC Neuroscience, 2011
Background According to several lines of evidence, the great expansion observed in the primate prefrontal cortex (PfC) was accompanied by the emergence of new cortical areas during phylogenetic development.

Utilisation des sécrétions de myriapodes chez les lémurs et les sapajous : fonction curative ou signalisation sociale ?

Revue de Primatologie, 2011
Body-rubbing with millipedes is repeatedly documented in primates living under natural conditions, mainly in capuchin monkeys (Cebus spp.). Various functional (zoopharmacognosy, ingestion, social) and non-functional hypotheses (sensory, auto stimulation)

Impact of lactation upon fertility in the New World primate capuchin monkey (Cebus apella)

Journal of Medical Primatology, 2000
In the present paper, we have studied the impact of lactation upon fertility in the capuchin monkey, Cebus apella, under laboratory conditions. Nursing females (ten females, 12 postpartum periods) presented lactational amenorrhea (first menses at 159.2±9.0 vs 42.6±5.8 days postpartum in five non‐nursing females, seven postpartum periods).

Dissecting the mechanisms of squirrel monkey (Saimiri boliviensis) social learning [PDF]

PeerJ, 2013
Although the social learning abilities of monkeys have been well documented, this research has only focused on a few species. Furthermore, of those that also incorporated dissections of social learning mechanisms, the majority studied either capuchins ...

Health Correlates of Extended Longevity in Captive Ring-Tailed Lemurs (Lemur catta). [PDF]

Am J Primatol
Male and female ring‐tailed lemurs exhibit distinct patterns of age‐related change in certain serum chemistry markers. Photo by David Haring. ABSTRACT Captive primates maintained at accredited institutions can live extraordinarily long lives and, as a result, are useful models for understanding the physiology of aging. Many institutions monitor primate

Tracing the evolutionary history of the morpho‐anatomy of baculum in primates

The Anatomical Record, EarlyView.
Abstract Animal morphology reflects both evolutionary history and present‐day adaptation. Male mammal copulatory structures such as the baculum (penile bone) are ideal for studying these processes because of their complexity and high interspecific variability. In primates, however, research has focused mostly on baculum length.

Monkeys (Macaca mulatta and Cebus apella) and human adults and children (Homo sapiens) compare subsets of moving stimuli based on numerosity

Frontiers in Psychology, 2011
Two monkey species (Macaca mulatta and Cebus apella) and human children and adults judged the numerousness of two subsets of moving stimuli on a computer screen. Two sets of colored dots that varied in number and size were intermixed in an array in which

Visual responses of ganglion cells of a New‐World primate, the capuchin monkey, Cebus apella

The Journal of Physiology, 2000
1. The genetic basis of colour vision in New-World primates differs from that in humans and other Old-World primates. Most New-World primate species show a polymorphism; all males are dichromats and most females trichromats. 2. In the retina of Old-World primates such as the macaque, the physiological correlates of trichromacy are well established ...
