Multiple sex chromosome systems in howler monkeys (Platyrrhini, Alouatta) [PDF]
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 ...

Taxonomic review of Saguinus mystax (Spix, 1823) (Primates, Callitrichidae), and description of a new species [PDF]
Although the Amazon has the greatest diversity of primates, there are still taxonomic uncertainties for many taxa, such as the species of the Saguinus mystax group.

The Evolution of Primate Short-Term Memory [PDF]
Short-term memory is implicated in a range of cognitive abilities and is critical for understanding primate cognitive evolution. To investigate the effects of phylogeny, ecology and sociality on short-term memory, we tested the largest and most diverse ...

Contribution à l’étude de la mobilité de l’hallux et de la phylogénie des primates actuels
Material and methods: 51 anatomical specimens of non-human primates were dissected (18 embalmed, 33 fresh). The amplitudes of the medial cuneometatarsal and metatarsophalangeal articulations of the first ray of the foot of the various fresh pieces and ...
