The origin and evolution of neotropical primates

open access: yes, 2008
A significant event in the early evolution of Primates is the origin and radiation of anthropoids, with records in North Africa and Asia. The New World Primates, Infraorder Platyrrhini, have probably originated among these earliest anthropoids morphologically and temporally previous to the catarrhine/platyrrhine branching .

Sistemas de apareamiento en un primate neotropical (Alouatta caraya) / Mating in neotropical primate (Alouatta caraya)

open access: yesRevista Argentina de Antropología Biológica, 2015
La socioecología de primates no humanos provee un marco para comprender la evolución de varios aspectos de la conducta de nuestros antepasados. Un aspecto relevante de la evolución de los sistemas sociales es la descripción de los sistemas de apareamiento, que dependen de una combinación de estudios genéticos y comportamentales.

Distribution patterns of Neotropical primates (Platyrrhini) based on Parsimony Analysis of Endemicity

open access: yesBrazilian Journal of Biology
The Parsimony Analysis of Endemicity (PAE) is a method of historical biogeography that is used for detecting and connecting areas of endemism. Based on data on the distribution of Neotropical primates, we constructed matrices using quadrats, interfluvial
