Polymorphic color vision in captive Uta Hick's cuxiús , or bearded sakis ( Chiropotes utahickae )
The pitheciines (Chiropotes, Pithecia, and Cacajao) are frugivorous Neotropical primates that specialize on the predation of seeds from unripe fruits, usually cryptic against the foliage. However, little is known about the color vision distribution within this taxon, and even less about the abilities shared by these animals regarding discrimination of chromatic targets. The aim of this study was to evaluate the color vision perception of captive …
A Molecular Phylogeny of Living Primates
Comparative genomic analyses of primates offer considerable potential to define and understand the processes that mold, shape, and transform the human genome. However, primate taxonomy is both complex and controversial, with marginal unifying consensus of the evolutionary hierarchy of extant primate species. Here we provide new genomic sequence (~8 Mb) from 186 primates representing 61 (~90%) of the described genera, and we include outgroup speci…
Population genetic studies of Alouatta belzebul from the Amazonian and Atlantic Forests
Cytochrome b DNA sequence data (ca. 1,140 bp) of 66 Alouatta belzebul from the Amazonian and the Atlantic Forests of Brazil were used for phylogenetic reconstructions and population studies. Our sample consisted of 60 specimens from the Amazonian Forest (captured in 1984 and 1998 in Pará‐PA state) and six specimens from the Atlantic Forest (Paraíba‐PB state). We found 32 haplotypes, 23 in PA‐1984 (with 12 present in more than one individual), 11 …
MtDNA Haplogroup Analysis of Black Brazilian and Sub-Saharan Populations: Implications for the Atlantic Slave Trade
Seventy individuals from two African and four black Brazilian populations were studied for the first hypervariable segment of mtDNA. To delineate a more complete phylogeographic scenario of the African mtDNA haplogroups in Brazil and to provide additional information on the nature of the Atlantic slave trade, we analyzed our data together with previously published data. The results indicate different sources of African slaves for the four major B…
Sequences from the 5′ flanking region of the ε‐globin gene support the relationship of Callicebus with the pitheciins
The purpose of this study was to determine nucleotide sequences from the 5′ flanking region of the ε-globin gene of selected platyrrhine primates and to analyze the data for phylogenetic information and estimated times of divergence. We report new sequence data for two species of New World monkeys, Callicebus torquatus and Pithecia irrorata. We analyzed these data in conjunction with homologous sequences from other primate species. The data suppo…
Genetic diversity of two African and sixteen South American populations determined on the basis of six hypervariable loci
A total of 582 individuals (1,164 chromosomes) from two African, eight African-derived South American, five South American Amerindian, and three Brazilian urban populations were studied at four variable number of tandem repeat (VNTR) and two short tandem repeat (STR) hypervariable loci. These two sets of loci did not show distinct allele profiles, which might be expected if different processes promoted their molecular differentiation. The two Afr…

Molecular phylogeny of the New World monkeys (Platyrrhini, primates) based on two unlinked nuclear genes: IRBP intron 1 and ε-globin sequences
Nuclear sequences of the 1.8 kilobase (kb) long intron 1 of the interstitial retinol-binding protein gene (IRBP), previously determined for 11 of the 16 extant genera of New World monkeys (superfamily Ceboidea, infraorder Platyrrhini), have now been determined for the remaining 5 genera. The maximum parsimony trees found, first with IRBP sequences alone and then with tandemly combined IRBP and epsilon-globin gene sequences from the same species, …
Biochemical diversity and genetic distances in the Pitheciinae subfamily (primates, platyrrhini)
Protein electrophoretic variability in Saimiri and the question of its species status
An electrophoretic survey of 15 protein systems (22 loci) was employed to determine the genetic relationships among 9 populations (441 individuals) of South American squirrel monkeys ( Saimiri sciureus sciureus, S. sciureus boliviensis , and S. sciureus ustus ). Genetic markers capable of differentiating the second from the two other taxa were observed mainly in the ADA and GPI systems. Heterogeneity for ADA and CA2 between populations from oppos…

Divergence between biochemical and cytogenetic differences in three species of the Callicebus moloch group
Specimens from three species of the Callicebus moloch group—C. Moloch (N = 80), C. brunneus (N = 166), and C. cupreus (N = 23)—were studied. Twenty genetic loci were investigated through electrophoresis, genetic distances were estimated, and the results compared with the available cytogenetic data. Low values of genetic distance were encountered, contrasting with relatively large chromosome differences. We propose that recent karyotypic rearrange…

Coat color and biochemical variation in Amazonian wild populations of Alouatta belzebul
A comparative study of 13 blood genetic systems and pelage color variation was performed in four wild populations of Alouatta belzebul. The animals from the west bank of the Tocantins River showed less color variation than those from the east bank, as well as less than those from Tocantins Island. The blood genetic markers, however, revealed an opposite pattern of variation. A previously undescribed morphological variant (completely red) was obse…
Esterase D in Brazilian Saguinus midas niger —results and comparison with previous studies in Anthropoidea
Four esterase D (ESD) phenotypes, presumably resulting from the segregation of three alleles with moderate polymorphic frequencies, were observed in a sample of the black handed tamarin, Saguinus midas niger , from the northern Amazonian region (Brazil). Previous surveys in the non‐human Anthropoidea indicate that the ESD locus is polymorphic in at least 4 of the 19 taxonomic entities listed
