Positive selection on the growth hormone and its association with size evolution in Platyrrhini

, 2008
As bases moleculares da diversidade fenotipica dentro de espécies são de grande interesse aos biólogos evolutivos porque a evolução morfológica adaptival depende da seleção de variantes genéticas.

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

Brazilian 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

Searching for the Haplorrhine Heterotherm: Field and Laboratory Data of Free-Ranging Tarsiers

Frontiers in Physiology, 2017
The observation of heterothermy in a single suborder (Strepsirrhini) only within the primates is puzzling. Given that the placental-mammal ancestor was likely a heterotherm, we explored the potential for heterothermy in a primate closely related to the ...
