Social behavior of the emperor tamarin in captivity
Variance in intrinsic rates of growth among free‐ranging rhesus monkey groups
Differential rates of intrinsic growth for the population of Macaca mulatta on Cayo Santiago partitioned by social group and dominance rank of genealogies indicate that the potential for increase is not uniformly distributed throughout the population. In the period from 1973 to 1974, high‐ranking genealogies were growing at a faster rate than low‐ranking genealogies. Large differences in r among the social groups indicate the possible existence o…

Sociometrics of Macaca mulatta
The concept of the linear dominance hierarchy and a much less precise notion of a central/peripheral ordering of individuals have been prominent among the ideas about social organization of monkey groups. Although the latter has seldom been quantified, the ranks of individuals in the two orders are usually assumed to be correlated. This paper reports on a longitudinal study of a free‐ranging group of rhesus monkeys. The individual histories of pr…
Group selection models with population substructure based on social interaction networks
Most models of evolution by group selection assume that groups have discrete boundaries with homogeneous levels of interaction within groups and no interaction between groups. While this assumption is analytically useful, it is not an accurate description of groups in nature. We use a generalization of D.S. Wilson's ( Am. Nat. 111 :157–185, 1977; The Natural Selection of Populations and Communities. Reading, Mass.: Benjamin/Cummings, 1980) concep…
Evolution as Entropy
Demographic components of gene frequency change in free‐ranging macaques on Cayo Santiago
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…
Patterns of group splitting within matrilineal kinship groups
Social group fission and the origin of intergroup genetic differentiation among the rhesus monkeys of Cayo Santiago
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…
Genetic studies of serum transferrins of free‐ranging rhesus macaques of Cayo Santiago, Macaca mulatta (Zimmerman 1780)
Transferrin phenotypes of plasma from 687 semi‐free‐ranging Macaca mulatta living on Cayo Santiago, Puerto Rico, were determined by starch‐gel electrophoresis and autoradiography. Fifteen phenotypes, homozygous or heterozygous products of six codominant autosomal alleles, were present in the population. The 687 animals, prior to March 1973, were divided into eight troops plus peripheral males. By March 1, 1973 the size of the population was reduc…
Primate red cell enzymes
Glucose‐6‐phosphate dehydrogenase (E. C.: 1.1.1.49) phenotypes and 6‐phosphogluconate dehydrogenase (E. C.: 1.1.1.44) phenotypes were determined by starch‐gel electrophoresis of red cell hemolysates of Galago crassicaudatus subspp., Propithecus verreauxi, Lemur spp., Hapalemur griseus , and Macaca mulatta . A single glucose‐6‐phosphate dehydrogenase (G6PD) phenotype was found in each species. A single 6‐phosphogluconate dehydrogenase (6PGD) pheno…
An ethogram for rhesus monkeys I. Antithetical contrasts in posture and movement
Antithetical postures and movements in social displays of rhesus monkeys distinguish five moods. Movement from a high to a low position in the midsagittal plane indicates threat. Emphasis on movement in the frontal plane indicates subordinance. Movement from a low to a high position in the midsagittal plane indicates non‐hostile, non‐fearful approach. Oblique movements indicate a querying mood. Playfulness is indicated by emphasis on rotatory mov…
Some aspects of parent‐offspring and sibling relations in a group of rhesus monkeys, with a discussion of grooming
Observations of a group of rhesus monkeys living on Cayo Santiago, Puerto Rico show (1) that a rhesus female and her offspring can continue to maintain a distinct relation into the offspring's physical maturity, and (2) that the offspring often develops its strongest relations with monkeys of its own genealogy. Detailed descriptions of relations in several of the genealogies illustrate the above points. The observer identifies relations by the co…
