Threat Analysis of Forest Fragmentation and Degradation for Peruvian Primates

open access: yesDiversity, 2023
Peru has 55 primate taxa (including all species and subspecies), a third of which are threatened. The major drivers of habitat loss, degradation and fragmentation are grazing, forestry, agriculture and transport infrastructure.

The current status of the New World monkey phylogeny

open access: yesAnais da Academia Brasileira de Ciências, 2000
Four DNA datasets were combined in tandem (6700 bp) and Maximum parsimony and Neighbor-Joining analyses were performed. The results suggest three groups emerging almost at the same time: Atelidae, Pitheciidae and Cebidae.

A RAD-sequencing approach to genome-wide marker discovery, genotyping, and phylogenetic inference in a diverse radiation of primates. [PDF]

open access: yesPLoS ONE, 2018
Until recently, most phylogenetic and population genetics studies of nonhuman primates have relied on mitochondrial DNA and/or a small number of nuclear DNA markers, which can limit our understanding of primate evolutionary and population history.

Pinworms of the red howler monkey (Alouatta seniculus) in Colombia. Gathering the pieces of the pinworm-primate puzzle [PDF]

open access: yes, 2020
Pinworms of primates are believed to be highly host specific parasites, forming co-evolutionary associations with their hosts. In order to assess the strength and reach of such evolutionary links, we need to have a broad understanding of the pinworm ...

Primate ABO Gene is under Weak Positive Selection

open access: yesNotulae Scientia Biologicae, 2012
ABO locus presents three main alleles: A, B and O. A and B encode glycosyltransferases that catalyze the addiction of an N-GalNac and D-galactose to a precursor substance (H substance), producing A and B antigens, while the O allele does not produce a ...

Color vision and niche partitioning in a diverse neotropical primate community in lowland Amazonian Ecuador

open access: yesEcology and Evolution, 2021
A recent focus in community ecology has been on how within‐species variability shapes interspecific niche partitioning. Primate color vision offers a rich system in which to explore this issue. Most neotropical primates exhibit intraspecific variation in

Centromeric enrichment of LINE-1 retrotraposon in two species of South American monkeys Alouatta belzebul and Ateles nancymae (Platyrrhini, Primates)

open access: yesCaryologia, 2022
LINE-1 are retrotransposable elements, a kind of repetitive DNA included in the heterochromatin regions of chromosomes. Repetitive DNA represent one of the major genomic components which role is not still clear challenging genomic assembly.

Predation on Alouatta guariba clamitans Cabrera (Primates, Atelidae) by Leopardus pardalis (Linnaeus) (Carnivora, Felidae) [PDF]

open access: yesRevista Brasileira de Zoologia, 2005
There are a few studies about predation on primates. Howler monkeys, being relatively large animals, were believed to be preyed on successfully only by medium to large-sized carnivores and large birds of prey. Our study took place at Chácara Payquerê, which is situated in the municipality of Balsa Nova, State of Paraná, Southern Brazil.

Genetic structure in two northern muriqui populations (Brachyteles hypoxanthus, Primates, Atelidae) as inferred from fecal DNA

open access: yesGenetics and Molecular Biology, 2008
We assessed the genetic diversity of two northern muriqui (Brachyteles hypoxanthus Primata, Atelidae) populations, the Feliciano Miguel Abdala population (FMA, n = 108) in the Brazilian state of Minas Gerais (19°44' S, 41°49' W) and the Santa ...

Molecular variation in AVP and AVPR1a in New World monkeys (Primates, Platyrrhini): evolution and implications for social monogamy. [PDF]

open access: yesPLoS ONE, 2014
The neurohypophysial hormone arginine vasopressin (AVP) plays important roles in fluid regulation and vascular resistance. Differences in AVP receptor expression, particularly mediated through variation in the noncoding promoter region of the primary ...
