MHC-DRB heterozygosity may increase subordinate but not alpha male siring success in white-faced capuchin monkeys (Cebus imitator)
Morphometric disparities in skull size and shape of capuchin monkeys (Cebidae: (Cebus) in northern South America and Central America
Mitochondrial DNA for Phylogeny Building: Assessing Individual and Grouped mtGenes as Proxies for the mtGenome in Platyrrhines
Phylogenetic trees are analytic tools used in primate studies to elucidate evolutionary relationships. Because of its relative ease to sequence and rapid evolution compared to nuclear genomes, mitochondrial DNA is frequently used for phylogeny building. This project evaluated the effectiveness of using individual or grouped mitochondrial genes (mtGenes) as a proxy for the mitochondrial genome (mtGenome) in phylogeny building within two nested pri…
Stone Tool Use by Black‐Horned Capuchin Monkeys ( Sapajus nigritus cucullatus ) in an Urban Park in Londrina, Brazil
Tool use to crack open palm nuts has been observed extensively in some capuchin monkey species. However, for southern black‐horned capuchin monkeys ( Sapajus nigritus cucullatus ), there is only one published record of stone tool use from the 1990s, from an urban park in Londrina, Brazil. In the present study, we returned to this urban park to systematically investigate the hammer‐and‐anvil sites used to crack nuts by this capuchin monkey populat…
Range Extension for Critically Endangered Sapajus xanthosternos, with Observations of Stone Tool Use at the Lower Limit of Habitat Suitability
Niche Expansion and the Natural History of Human-Cat Kinship
Domestic cats (Felis catus) have flourished alongside humans for 10,000 years. What accounts for this success? We argue here that cats and humans collaborate in this success because cats are very good at niche expansion across multiple dimensions into new human-facilitated niche space and at niche space saturation across both new and old niche spaces. Cats are neither simply biologically adapted nor simply domesticated by humans but possess their…
News and Perspectives: Words matter in primatology
Postings on social media on Twitter (now X), BioAnthropology News (Facebook), and other venues, as well as recent publications in prominent journals, show that primatologists, ecologists, and other researchers are questioning the terms “Old World” and “New World” due to their colonial implications and history. The terms are offensive if they result in erasing Indigenous voices and history, ignoring the fact that Indigenous peoples were in the Ame…
Phylogeography, genetic diversity, and intraspecific genetic structure of the black‐horned capuchin ( Sapajus nigritus )
Recent molecular studies have clarified the overarching taxonomy of capuchin monkeys, but intraspecific genetic diversity remains unexplored for most capuchin species. One example is Sapajus nigritus , the southernmost capuchin monkey, found in Brazil and Argentina; its phenotypic diversity has been recognized as two geographic subspecies, but the intraspecific genetic structure of this taxon is poorly known. Here, we sampled across most of this …
Diet, activity patterns, and home range use in forest and cultivated areas for one wild group of endangered crested capuchin monkeys ( Sapajus robustus ) in Reserva Natural Vale, Espírito Santo, Brazi…
Robust capuchin monkeys ( Sapajus spp.) are distributed widely in the Neotropics and may be able to survive in modified landscapes because of their omnivorous, opportunistic diet. The poorly known and endangered crested capuchin monkey ( Sapajus robustus ) is endemic to the Atlantic Forest in Bahia, Minas Gerais and Espírito Santo states, Brazil. We collected data on diet and home range for a crested capuchin group with access to forest and culti…
A robust tool kit: First report of tool use in captive crested capuchin monkeys ( Sapajus robustus )
Primate tool use is of great interest but has been reported only in a limited number of species. Here we report tool use in crested capuchin monkeys ( Sapajus robustus ), an almost completely unstudied robust capuchin species. Crested capuchins and their sister species, the yellow‐breasted capuchin, diverged from a common ancestor over 2 million years ago, so this study fills a significant gap in understanding of tool use capacity and variation w…
Polymorphism of the 3′-UTR of the dopamine transporter gene (DAT) in New World monkeys
Reduced range of the endangered crested capuchin monkey ( Sapajus robustus ) and a possible hybrid zone with Sapajus nigritus
The crested capuchin monkey ( Sapajus robustus ) is an endangered species endemic to the highly fragmented Atlantic Forest of Brazil. Surveys for S. robustus were carried out over a 25‐month period (2003–2005) to obtain more precise geographical limits for the western range of the species. Previously published localities for S. robustus were mapped, and each point was given a 25‐km radius “buffer zone.” The largest forest remnants in the buffer z…
The Monkeying of the Americas: Primate Biogeography in the Neotropics
Monkeys first arrived in the Neotropics about 36 Ma, and the ancestry of all living Neotropical primates (Platyrrhini) traces to a single common ancestral population from 24 to 19 Ma. The availability of lush Amazonian habitat, the rise of the Andes, the transition from the lacustrine to riverine system in the Amazon Basin, and the intermittent connection between the Amazon and the Atlantic tropical forests have all shaped how primates spread and…
C ebus Phylogenetic Relationships: A Preliminary Reassessment of the Diversity of the Untufted Capuchin Monkeys
The untufted, or gracile, capuchin monkeys are currently classified in four species, C ebus albifrons , C . capucinus , C . olivaceus , and C . kaapori , with all but C . kaapori having numerous described subspecies. The taxonomy is controversial and their geographic distributions are poorly known. C ebus albifrons is unusual in its disjunct distribution, with a western and central A mazonian range, a separate range in the northern A ndes in C ol…
Scream–embrace displays in wild black‐horned capuchin monkeys
Reintroduction of capuchin monkeys ( Cebus apella ) into their social group in captivity can elicit sirena screams and embraces. Captive scream–embrace displays are male biased, and females never perform sirena screams. One hypothesis is that scream–embrace displays serve a tension‐reduction or reconciliatory function between males with conflicting interests. Alternatively, these displays may function to maintain strong affiliative bonds between …
Coming of age: Steroid hormones of wild immature baboons ( Papio cynocephalus )
Large gaps exist in our knowledge about common patterns and variability in the endocrinology of immature nonhuman primates, and even normal hormonal profiles during that life stage are lacking for wild populations. In the present study we present steroid profiles for a wild population of baboons ( Papio cynocephalus ) from infancy through reproductive maturation, obtained by noninvasive fecal analyses. Fecal concentrations of glucocorticoid (fGC)…
Life‐history correlates of steroid concentrations in wild peripartum baboons
Steroid concentrations during late pregnancy and early lactation may be affected by both a female's reproductive history and her current condition, and may in turn predict subsequent life‐history events, such as offspring survival. This study investigated these relationships in a wild primate population through the use of fecal steroid analysis in repeated sampling of peripartum baboons ( Papio cynocephalus ). Fecal samples were collected from 32…
Hormonal changes during the mating and conception seasons of wild northern muriquis ( Brachyteles arachnoides hypoxanthus )
We investigated hormonal and behavioral changes in wild male and female northern muriquis ( Brachyteles arachnoides hypoxanthus ) at the Estação Biológica de Caratinga, Minas Gerais, Brazil, during a 6‐mo period that encompassed the onset of the 1998–1999 mating and conception seasons. Individual females resumed mating with the resumption of ovarian cycling, which was not synchronized among them or related to their cortisol levels. Females experi…
