  • Prosimian hemoglobins

    Open AccessLawrence K Duffy, Margaret M Ehrhardt et al.ARTICLEAmerican Journal of Primatology1987

    The ring‐tailed lemur, Lemur catta , shows a two‐component hemoglobin phenotype after alkaline electrophoresis. A difference in the amino acid sequence of the isolated α‐globins was observed at position 15 (α I‐Gly, α II‐Lys) and can account for the electrophoretic pattern of two hemoglobin components. Only one other amino acid difference was found in the sequence of the two globin chains: a neutral substitution occurs at position 53 (α I‐Gly, α …

  • Demographic components of gene frequency change in free‐ranging macaques on Cayo Santiago

    Open AccessCarole Ober, THOMAS J OLIVIER et al.ARTICLEAmerican Journal of Physical…1984Citada por: 4Referencias: 26

    Gene frequency profiles from January 1973 to January 1977 for three polymorphic loci were examined in Cayo Santiago rhesus social groups. The effects of demographic components (i.e., births, deaths, immigrations, emigrations, and group fission and fusion) on total change in gene frequencies are assessed. Allelic frequencies at the carbonic anhydrase II, 6‐phosphogluconate dehydrogenase, and transferrin loci were analyzed in four social groups. In…

  • Models for lineal effects in rhesus group fissions

    Open AccessJohn Buettner‐janusch, THOMAS J OLIVIER et al.ARTICLEAmerican Journal of Physical…1983Citada por: 4Referencias: 18

    Gene distributions in daughter groups produced by three rhesus monkey group fissions are analyzed. Data employed are for the Tf, 6PGD, and CA II electrophoretic marker systems in the fissions producing new daughter groups F and M, F and O, and J and N in the Cayo Santiago rhesus colony. Wide variations in F ST values were observed among the different markers in the various fissions. Overall, the observed F ST values exceeded predictions of simple…

  • Chromosomes of Lemuriformes. IV. Karyotype evolution in Lemur fulvus collaris (E. Geoffroy 1812)

    Open AccessJohn Buettner‐janusch, Andrew E HamiltonARTICLEAmerican Journal of Physical…1979

    The G‐banded karyotype of a feral Lemur fulvus collaris has a diploid number of 52; the nombre fondamental is 64. The karyotype consists of 6 pairs of biarmed autosomes, 19 pairs of acrocentric autosomes, and acrocentric sex chromosomes. Comparisons of the 2N = 52 complement with the 2N = 50 and 2N = 51 karyotypes published by Hamilton et al. ('77) supports the view that hybridization occurs naturally between animals with diploid numbers of 50 an…

  • Statistical methods for analyzing data on daily activity cycles of primates

    Open AccessRobert W Sussman, William M O'fallon et al.ARTICLEAmerican Journal of Physical…1979Citada por: 2Referencias: 10

    Many fields studies on primates have recently been carried out in which quantitative data have been collected using instantaneous scan sampling techniques. However, data collected in this manner are difficult to analyze statistically because of the problem of independence of samples, and a number investigators have analyzed such data incorrectly. In this paper, we evaluate such analyses and suggest alternative techniques that may be more appropri…

  • Social group fission and the origin of intergroup genetic differentiation among the rhesus monkeys of Cayo Santiago

    Open AccessJames M Cheverud, John Buettner‐janusch et al.ARTICLEAmerican Journal of Physical…1978Citada por: 19Referencias: 12

    The serum transferrin locus is used to investigate the roles of the lineal effect of fission, male migration effect of fission, and genetic drift in causing intergroup genetic differentiation among the rhesus macaques of Cayo Santiago. These three mechanisms prove sufficient to explain the degrees of differentiation between the newly formed social groups A, K, and L as of July 1, 1971. The lineal effect of fission provides a baseline of intergrou…

  • Carbonic anhydrase heterozygosity and F ST distributions in Kenyan baboon troops

    Open AccessCarole Ober, THOMAS J OLIVIER et al.ARTICLEAmerican Journal of Physical…1978Citada por: 8Referencias: 16

    An analysis of the distribution of carbonic anhydrase alleles in troops of olive baboons, Papio cynocephalus , is reported. In an earlier study (Olivier, T. J., J. Buettner‐Janusch and V. Buettner‐Janusch, 1974, Am. J. Phys. Anthrop., 41 : 175–190) the authors found a significant excess of heterozygotes with a large amount of intertroop differentiation at the CA II locus. If balancing selection is acting on the CA II locus and maintaining an exce…

    Open AccessJohn Buettner‐janusch, Marlene SockolARTICLEAmerican Journal of Physical…1977

    Phenotypes of eight red cell enzymes at nine genetic loci were determined in the semi‐free‐ranging population of rhesus macaques, Macaca mulatta , that inhabit Cayo Santiago. The following enzymes were examined electrophoretically: adenosine deaminase, glucose‐6‐phosphate dehydrogenase, glyceraldehyde‐3‐phosphate dehydrogenase, indophenol oxidase, lactate dehydrogenase, malate dehydrogenase, phosphoglucomutase‐1, phosphoglucomutase‐2, and purine …

  • Chromosomes of lemuriformes. II. Chromosome polymorphism in Lemur fulvus collaris (E. Geoffroy 1812)

    Open AccessAndrew E Hamilton, John Buettner‐janusch et al.ARTICLEAmerican Journal of Physical…1977

    Two previously unreported diploid numbers, 2N = 50 and 2N = 51, from five individual Lemur fulvus collaris are described. In both chromosome complements, the nombre fondamental is 64. The 2N = 50 complement is composed of 7 pairs of bi‐armed chromosomes, 17 pairs of acrocentric chromosomes with small short arms, and acrocentric sex chromosomes. The 2N = 51 complement is identical with these exceptions: Only one member equivalent to bi‐armed pair …

  • Genetic studies of free‐ranging macaques of Cayo Santiago II. 6‐Phosphogluconate dehydrogenase and Nadh‐methemoglobin reductase (Nadh‐diaphorase)

    Open AccessJohn Buettner‐janusch, Marlene SockolARTICLEAmerican Journal of Physical…1977

    For the population of 395 semi‐free‐ranging rhesus macaques ( Macaca mulatta ) that inhabited Cayo Santiago in 1976, 6‐phosphogluconate dehydrogenase phenotypes of 378 animals were determined. Three phenotypes, controlled by two autosomal codominant alleles, PGD A and PGD B , were found by electrophoretic methods. The frequencies of the alleles are 0.898 and 0.102, respectively. The population, composed of five troops and peripheral males, is in …
