  • Pattern in craniofacial biology: Evidence from the old world monkeys (Cercopithecidae)
    International Journal of Primatology, 1994
    Co-Authors: Matthew J. Ravosa, Brian T. Shea
    Abstract:

    An understanding of craniofacial growth, both evolutionarily and clinically, requires an investigation of pattern — geometric relations that remain relatively constant among growing structures or components of the skull. Several craniofacial biologists have suggested that specific morphological relations remain invariant during growth and in interspecific comparisons of adults of varying size. We tested the hypothesized invariance of a series of craniofacial angles in a sample of adult Old World monkeys. Fifteen angles were determined from lateral cranial radiographs. Criteria for examining angular invariance included tests for significant correlations and regression slopes with palatal length (overall skull size), tests for significant mean differences (ANOVAs) in angular values between the two subfamilies of Cercopithecidae — Cercopithecinae and Colobinae — and the computation and ranking of standard deviations (SDs) and coefficients of variation (CVs). Results indicate that most of the cranial angles purported to be invariant do not in fact meet the criteria for acceptance. One of the few cranial angles that evinces a somewhat constant value is that between the posterior maxillary plane and the neutral axis of the orbits, providing very limited support for Enlow’s (1982) claim that this region represents a fundamental anatomical interface (at least within Old World monkeys). Our analysis suggests that while there may be several relatively invariant structural relations within the skull, most of those previously discussed as representing evidence of pattern in primate-wide or mammal-wide comparisons are incorrect .

  • hematology and serum chemistry in the white crowned mangabey cercocebus torquatus lunulatus and in the mandrill mandrillus sphinx
    Journal of Medical Primatology, 1996
    Co-Authors: Victor I Peinado, Ginés Viscor, J. F. Celdrán, Jorge Palomeque
    Abstract:

    : Reference values of some hematologic and plasma chemical parameters were established in two species of clinically normal Cercopithecidae. The following variables were studied in seven mandrills (Mandrillus sphinx) and nine white-crowned mangabeys (Cercocebus torquatus lunulatus): hematocrit, hemoglobin concentration, erythrocyte and leucocyte counts, mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, glucose, urea, uric acid, cholesterol, creatinine, aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, creatinine phosphokinase, lactic dehydrogenase, gamma glutamyl transpeptidase, total serum proteins, albumin, globulins, albumin-globulin ratio, sodium, potassium, calcium, magnesium, total phosphorus, chloride, and serum osmolality. Few differences were observed when compared with human hematological data and with other species of Cercopithecidae Primates.

  • Cercopithecidae from the Pliocene of Saint-Vallier Cercopithecidae du Plioc6ne de Saint-Vallier
    2004
    Co-Authors: Eric Delson
    Abstract:

    The mid-Pliocene mammalian faunal locality of Saint-Vallier has yielded two isolated cercopithecine primate teeth, an T 1 and a dP 3. Both are most similar is size and morphology to those of macaques, such as the extant Macaca sylvanus, to which species the Saint-Vallier population is referred (perhaps as part of a temporal subspecies M. sylvanusflorentina). Such macaques would have been able to tolerate a cool climate but would probably have required some trees in which to sleep and feed.
