Radiographic estimation of long bone cross‐sectional geometric properties
Because of their biomechanical significance, cross‐sectional geometric properties of long bone diaphyses (areas, second moments of area) have been increasingly used in a number of form/function studies, e.g., to reconstruct body mass or locomotor mode in fossil primates or to elucidate allometric scaling relationships among extant taxa. In the present study, we test whether these biomechanical section properties can be adequately estimated using …
Taxonomic status of Saguinus tripartitus (Milne‐Edwards, 1878)
A review of specimens and field notes of Carlos Olalla and his sons showed that they collected Saguinus tripartitus and Saguinus fuscicollis lagonotus at the same place on the right bank of the lower Rio Napo in Peru. Thus, these two forms are sympatric, although they probably occur in different habitats. Therefore, Saguinus tripartitus should be treated as a distinct species, not as a subspecies of Saguinus fuscicollis
Forelimb anatomy of new world monkeys: Myology and the interpretation of primitive anthropoid models
The forelimbs of 12 genera of New World monkeys, two genera of Old World monkeys, and a gibbon were dissected. Of the 54 muscles examined, 19 exhibited significant intergeneric variation. We present arguments for which morphologies are primitive and which are derived within platyrrhines and within anthropoids. We conclude that the forelimbs of Cebus apella and Callicebus moloch represent good models of the ancestral anthropoid morphology. Thus am…
A study of a black howling monkey ( Alouatta caraya ) population in northern Argentina
A population of Alouatta caraya in northern Argentina had an ecological density of 130 animals per km 2 . Mean troop size varied from 7.2 to 8.9 individuals, and the ratio of adult males to adult females from 0.58 to 0.51. Infants comprised from 6% to 14% of the population, juveniles from 16% to 21%. These percentages probably vary seasonally in response to a birth peak at the beginning of the dry season. Males were age‐graded in multi‐male troop…

Karyotypes of squirrel monkeys ( Saimiri sciureus ) from different geographic regions
Three different karyotypes have been found so far among Saimiri originating from five different South American localities. All animals examined have the same diploid number (44) of chromosomes but the number of acrocentric and submetacentric chromosomes varies, presumably as a result of pericentric inversions. Saimiri originating from Iquitos, Peru, consistently have ten acrocentric chromosomes; animals originating from Leticia, Colombia, have 12…
