We described the karyotypes detected in 23Aotus specimens captured on Southwestern Amazon region (63°30'W, 9°00'S). This region should be occupied byA. nigriceps. However, the animals described here have a fur pattern and a karyotypes similar to those ofA. azarae boliviensis andA. infulatus. The females presented 50 chromosomes and the males 49 as a consequence of fusion between the chromosome Y and an autosome. This sample presented polymorphisms of G- and C-banding and NOR-staining. These… 

mtDNA diversity in Azara's owl monkeys (Aotus azarai azarai) of the Argentinean Chaco.

An ancient phylogeographic discontinuity among Aotus species living north, south, and west of the Amazon River that began more than eight million years ago is observed and data point to a recent expansion of Azara's owl monkeys into the Argentinean Chaco.

Analysis of constitutive heterochromatin of Aotus (Cebidae, Primates) by restriction enzyme and fluorochrome bands

The chromosomal constitution of a population in the state of Rondonia, Brazil, whose karyotype typically presented a considerable accumulation of constitutive heterochromatin was described, with a banding pattern of C type, similar to that obtained using barium hydroxide.

Cytogenetic Investigations in Bornean Rhinolophoidea Revealed Cryptic Diversity in Rhinolophus sedulus Entailing Classification of Peninsular Malaysia Specimens as a New Species

Examination of the chromosomal set of male R. sedulus specimens from Borneo with 2n = 45 and a Neo-X1X2Y sex chromosome system revealed extreme differences to the karyotype of specimens from Peninsular Malaysia, resulting in the taxon being described as a new species.

Molecular Phylogenetics of Aotus (Platyrrhini, Cebidae)

The accurate identification of taxa of Aotus is essential for 1) the development of precise biomedical assays, 2) the determination of potential illegal traffic of this genus, and 3) conservation.

An Update on the Distribution of Primates of the Tapajós-Xingu Interfluvium, Central Amazonia

The need to conserve the primate fauna of this region is emphasized, as this portion of Amazonia is a target for development projects and is subject to strong pressures from logging and ranching activities.

Neotropical primate evolution and phylogenetic reconstruction using chromosomal data

Molecular cytogenetic data regarding the principal nodes of the Neotropical monkey tree have been reviewed, permitting us to discuss highly derived karyotypes characterized by a wide range of diploid numbers of chromosomes and variable chromosomal evolution with different rearrangement and polymorphism rates.

Mammalian Diversity and Matses Ethnomammalogy in Amazonian Peru Part 1: Primates

Comparisons of Matses observations about spider monkeys with the published results of scientific field research suggests that the Matses are generally accurate observers of primate natural history, a conclusion that is additionally supported by comparing community patterns of resource use compiled from interview data with community-ecological studies ofPrimate faunas in the scientific literature.



Cytogenetic studies of Aotus from Eastern Amazonia. Y/Autosome rearrangement

Twenty‐one specimens of Aotus were captured on both sides of the Tocantins river when the hydroelectric reservoir of Tucuruí, Brazil, was filled. The males had a diploid number of 49 chromosomes, and

TheAotus from northern Argentina

Eight specimens of Aotus from Argentina were studied and C- and G-banding patterns differed from those published for owl monkeys from other geographic regions.

Two new karyotypes in the Peruvian owl monkey (Aotus trivirgatus)

The chromosome complement of a “phenotype‐B” Aotus population from Peru was examined and it was indicated that the chromosome number polymorphism in these Peruvian owl monkeys resulted from a single fusion or fission event involving a single metacentric and two acrocentric chromosome pairs.

Aotus vociferans ×Aotus nancymai: Sympatry without chromosomal hybridation

Karyotype and coat pattern data suggest that A. vociferans and A. nancymai should indeed be distinct species of Aotus.

Chromosome evolution in the owl monkey, Aotus

The mechanism of chromosomal evolution is reconstructed and the hypothesis that isolated groups of ancestral individuals living in several confined areas have separately accumulated a fusion or inversion pair as a result of inbreeding is proposed.

XX/"XO" sex determination system in a population of Peruvian owl monkey, Aotus.

The chromosome complement of a group of owl monkeys with typical pelagic features characteristic of Aotus inhabiting the upper Amazonian region in South America was analyzed by various band techniques and substantiates the postulation that the owl monkey is an evolutionary actively diverging species.

Two new species of night monkeys, genus Aotus (Cebidae, platyrrhini): A preliminary report on Aotus taxonomy

The nine allopatric species of Aotus recognized represent two natural groups distinguished by karyotype, color, and pelage patterns, and a key to the species and subspecies gives the diagnostic characters of each.

Translocation of Y chromosome to an autosome in the Bolivian owl monkey, Aotus.

Karyotypic study of a population sample of owl monkeys, Aotus, revealed two sex-specific somatic diploid chromosome numbers: 49 for males and 50 for females, confirming the interpretation of a Y-autosome translocation in the males.

Banded chromosomes of the owl monkey, Aotus trivirgatus.

Chromosomes of the owl monkey with 2n=54, 53, or 52, have been stained to show quinacrine and Giemsa bands, and a karyotypic arrangement has been proposed based on lengths, centrometric index, and banding pattern.
