Amplification Dynamics of Platy-1 Retrotransposons in the Cebidae Platyrrhine Lineage. [PDF]

Genome Biol Evol, 2019
Platy-1 elements are Platyrrhine-specific, short interspersed elements (SINEs) originally discovered in the Callithrix jacchus (common marmoset) genome. To date, only the marmoset genome has been analyzed for Platy-1 repeat content.

Extending the Reach of Tooling Theory: A Neurocognitive and Phylogenetic Perspective. [PDF]

Top Cogn Sci, 2021
Abstract Tool use research has suffered from a lack of consistent theoretical frameworks. There is a plethora of tool use definitions and the most widespread ones are so inclusive that the behaviors that fall under them arguably do not have much in common.

Taxonomic and sex differences in sagittal cresting among gracile and robust capuchin monkeys. [PDF]

J Anat
In this study, I show that there are interspecific differences in the frequency and pattern of sagittal cresting among six capuchin species. Four of the six species show sagittal cresting, with Cebus capucinus showing a different sagittal cresting pattern to that observed in three robust capuchin species. All four crested species show sexual dimorphism

The Earliest Known Radiation of Pitheciine Primates. [PDF]

Am J Primatol
Right mandible and dentition of the holotype of Soriacebus ameghinorum (MACN Pv SC2), from the Early Miocene of Patagonia, compared with the living Cacajao calvus (FMNH 88813, cast), both representing extinct and extant morphologies of the Pitheciinae: Procumbent and styliform incisors and projecting canines represent a morphological complex for ...

Two hundred and five newly assembled mitogenomes provide mixed evidence for rivers as drivers of speciation for Amazonian primates. [PDF]

Mol Ecol, 2022
Abstract Mitochondrial DNA remains a cornerstone for molecular ecology, especially for study species from which high‐quality tissue samples cannot be easily obtained. Methods using mitochondrial markers are usually reliant on reference databases, but these are often incomplete.

Mitochondrial DNA for Phylogeny Building: Assessing Individual and Grouped mtGenes as Proxies for the mtGenome in Platyrrhines. [PDF]

Am J Primatol
ABSTRACT 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

Microsatellite Markers for Bearded Capuchins (Sapajus libidinosus): Transferability and Characterization [PDF]

Anais da Academia Brasileira de Ciências, 2021
Natural Sapajus libidinosus populations are in continuous decline due to fragmentation, habitat loss, and the illegal pet trade. They live in Caatinga scrub forests, which already lost over 50% of their original cover.

Characterization of Stone Tool Use in Wild Groups of Critically Endangered Yellow-Breasted Capuchin Monkeys (Sapajus xanthosternos). [PDF]

Am J Biol Anthropol
First camera trap video footage for wild Sapajus xanthosternos cracking resistant nuts with stone tools. ABSTRACT Objectives A hallmark of hominin evolution is the advent and diversification of stone tool use, and biological anthropologists have a particular interest in characterizing tool use behaviors in different hominin species.

Evolution of CEACAM pathogen decoy receptors in primates. [PDF]

Eur J Clin Invest
In humans, pathogen binding to the inhibitory receptor CEACAM1 on leukocytes allows immune escape while engagement of the neutrophil‐specific endocytic CEACAM3 decoy receptor enables destruction. Easily shed GPI‐linked epithelial CEACAM5 and CEACAM6 might act as soluble or extracellular vesicle‐bound decoy receptors.

Incisor cross-sectional area at the cementoenamel junction correlates with an increased reliance on frugivory in anthropoid primates. [PDF]

Anat Rec (Hoboken)
Abstract Diet is one of a limited set of key ecological parameters defining primate species. A detailed understanding of dental functional correlates with primate diet is a key component for accurate dietary inference in fossil primates. Although considerable effort has been devoted to understanding post‐canine dental function, incisor function remains
