Manipulative Tendencies of Captive Cebus albifrons
International Journal of Primatology, 1999We conducted two experiments to examine the manipulative tendencies of captive Cebus albifrons. In Experiment 1 we examined hand preference for reaching by providing subjects with food either on the cage floor (to facilitate quadrupedal reaching) or at the height of an upright subject's shoulder (to facilitate bipedal reaching).

Megaloblastic anemia and the requirement for folic acid in the cebus monkey (Cebus albifrons)
American Journal of Primatology, 1982AbstractTo study the development of folic acid deficiency, nine 3‐year‐old cebus monkeys (Cebus albifrons) were fed purified diets containing varying amounts of added folic acid. Monkeys fed the diet without added vitamin stopped growing and then lost weight.

Noradrenergic control of circadian rhythms in Cebus albifrons
American Journal of Physical Anthropology, 1973AbstractManifestation of biologic oscillations (e.g., body temperature 24‐hour wave form) is the summation of the exogenous and endogenous response mechanisms of the biologic clock. Biologic rhythm asynchrony results from a rapid change in the environment presented to the time sensors.

Development and Eruption of the Mandibular Cheek Teeth in Cebus albifron s
Folia Primatologica, 1982The development and eruption of the mandibular cheek teeth of Cebus albifrons is described from a longitudinal series of whole body radiographs. Males are generally ahead of females in both development and eruption times. The dental development and eruption in C.

Journal of Medical Primatology, 1986
Nitrogen (N) balance and growth were utilized to assess the efficiency of N utilization in the infant cebus monkey (Cebus albifrons). The efficiency of N utilization as calculated from N balance data was 35%. The efficiency of N utilization for growth was 37% as determined by weight change over a 28‐day trial and by body composition data from the ...

Postnatal heterochrony of the masticatory apparatus in Cebus apella and Cebus albifrons
Journal of Human Evolution, 1992Species of the genus Cebus have been characterized as omnivorous, although Cebus apella differs significantly from the other Cebus species in its ability to routinely consume hard fruits and nuts. Hard-object feeding behavior in C. apella is reflected in a suite of craniomandibular features that are related to the generation and dissipation of higher ...

Cebus albifrons (White-fronted capuchin)
1975These karyotypes came from blood cultures and were kindly donated by Dr. L.E.M. de Boer, Holland. The acrocentrics here displayed as the 22nd and 23rd pairs have a paracentromeric secondary constriction and often associate with one another. Other cebus species have similar karyotypes but only insufficient material has been collected to warrant a ...

Papillary Carcinoma of Apocrine Sweat Glands in a Capuchin Monkey (Cebus albifrons)
Journal of Medical Primatology, 1976A tumor removed from the skin of the right pectoral region of a 19-year-old male Capuchin monkey (Cebus albifrons) was morphologically classified as a papillary carcinoma of apocrine sweat gland origin. The designation of malignancy was based primarily on cellular pleomorphism and stromal invasion.

Abstract Cebus albifrons monkeys were used to study the relationship of the chiasmatic response evoked by light stimulation to various parameters of stimulation. The usual pattern of the gross response consisted of an early positive and a later positive-negative component which, to some extent, could be modified independently.

American Journal of Physical Anthropology, 1980
AbstractCebus albifrons and Cebus apella, partially sympatric capuchin monkeys from South America, are known to differ substantially in adult body mass and bodily proportions. C. apella possesses a robust, stocky build in contrast to the more gracile, relatively longer limbed body design of C. albifrons.
