FERRE, D et al. Use of cytogenetic and anthropometric variables for an efficient management of Neotropical Primates in captivity. InVet [online]. 2009, vol.11, n.2, pp.99-103. ISSN 1668-3498.

The neotropical primates which are part of the collection of the Mendoza Zoological Garden (ZMA) were object of a collaborative study that included the performance of anthropometrical measurements and classic cytogenetic analysis (alpha). Thirteen specimens of the genus Alouatta (10 females and 3 males), 2 Cebus sp. (1 male and 1 female) and 3 females of Saimiri sp. were studied. The karyological study allowed to confirm that the Cebus of ZMA corresponded to Cebus paraguayanus (2N=54, XX/XY) and the Saimiri to Saimiri boliviensis boliviensis species (2N = 44, XX). In the howler monkeys the species assignment was confirmed to A. caraya and a chromosomal morphology in the mitotic metaphases, compatible with the previously described and confirmed by meiosis, multiple sex determination system X₁X₁X₂X₂/X₁X₂Y₁Y₂, was observed. This opportunity allowed the ZMA to implementthe identification through the injection of numerated microchips that will facilitate its following and management.
