Capuchin monkeys (Cebus) are one of the genera with the widest distribution among Neotropical primates (New World Monkeys, Platyrrhini), accompanied by an elevated genetic, phenotypic, behavioral, morphological, and ...

In order to study the intra- and interspecific variability of the 14/15 association in Platyrrhini, we analyzed 15 species from 13 genera, including species that had not been described yet. The DNA libraries of human ...

In order to study the intergeneric variability of the Y chromosome, we describe the hybridization of the Y chromosome of Brachyteles arachnoides, obtained by microdissection, to metaphases of Ateles belzebuth marginatus, ...

O ancestral Platyrrhini (Primates) chegou na região Amazônica durante o Oligoceno e, desde então, a linhagem se divergiu em 3 famílias e 21 gêneros. Hoje, espécies estão distribuídas na Amazônia, Floresta Atlântica e nas ...

Background: Captive primates are often maintained in groups without geographic origin or genetic heritage information. This could lead to an incorrect assignment of species, which could result in an inadequate management ...

The estimation of phylogenetic relationships and divergence times among a group of organisms is a fundamental first step toward understanding its biological diversification. The time of the most recent or last common ...

Fragile sites are points of preferential breakage that may be involved in chromosome rearrangements. Induction of common fragile sites (c-fra) and spontaneous breakage were analyzed in two New World Monkeys species: Saimiri ...
