Phylogenetic inferences of Atelinae (Platyrrhini) based on multi-directional chromosome painting in Brachyteles arachnoides, Ateles paniscus paniscus and Ateles b. marginatus [PDF]
, 2005 We performed multi-directional chromosome painting in a comparative cytogenetic study of the three Atelinae species Brachyteles arachnoides, Ateles paniscus paniscus and Ateles belzebuth marginatus, in order to reconstruct phylogenetic relationships ...

Analysis of polimorphic NORs inAlouattaspecies (Primates, Atelidae) [PDF]
Caryologia, 1999 Nucleolar organizer regions were analyzed in four different species of Alouatta (Atelidae, Platyrrhini) using silver staining. They showed a high variability, appearing in dif- ferent numbers and positions, with a singular variation not found in other primate genera so far. Hence, the number of NOR-sites varied from four to six, while the number of NOR-

Sperm Morphology in Neotropical Primates
Animals, 2019 The morphological and morphometric characterization of spermatozoa has been used as a taxonomic and phylogenetic tool for different species of mammals. We evaluated and compared the sperm morphometry of five neotropical primate species: Alouatta caraya ...

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

Geographical variation of cshromosomal numberin Alouatta fusca damitans (Primates, Atelidae) [PDF]
Caryologia, 2000 Abstract A variation in the karyotype of Alouatta fusca clamitam from different geographical ranges is presented. Blood samples of six captive specimens from different States of Brazil were analyzed. Distinct diploid numbers were found: 2n=52, 2n=45 and 46. The odd number was due to Y-autosome translocation.

Multiple sex chromosome systems in howler monkeys (Platyrrhini, Alouatta) [PDF]
, 2014 In light of the multiple sex chromosome systems observed in howler monkeys (Alouatta Lacépède, 1799) a combined cladistic analysis using chromosomal and molecular characters was applied to discuss the possible origin of these systems.

Chromosomal distribution of interstitial telomeric sequences in nine neotropical primates (Platyrrhini): possible implications in evolution and phylogeny [PDF]
, 2016 To localize interstitial telomeric sequences (ITSs) and to test whether their pattern of distribution could be linked to chromosomal evolution, we hybridized telomeric sequence probes (peptide nucleic acid, PNA) on metaphases of New World monkeys ...
