The Role of Rivers as Geographical Barriers in Shaping Genetic Differentiation and Diversity of Neotropical Primates

open access: yesbioRxiv, 2023
We quantitatively tested the riverine barrier hypothesis and its influence on biogeographical distributions and molecular variation in New World monkeys (Parvorder: Platyrrhini). Using mitochondrial markers (cytochrome oxidase subunit II and cytochrome b)

Impact of human created environments in the pathogenic potential and antimicrobial resistance of staphylococci from wild neotropical primates in Brazil.

open access: yesComparative Immunology, Microbiology & Infectious Diseases, 2023
The non-human primate (NHP) Leontopithecus rosalia is an endangered species native of Brazil and lives in forest fragments with different levels of contact with humans (natural, private and urban). Other NHPs - Callithrix spp. - were introduced by humans

Workshop Summary: Neotropical Primates in Biomedical Research [PDF]

open access: yesILAR Journal, 2011
This report summarizes presentations and discussions at an NIH-sponsored workshop on Neotropical Primates in Biomedical Research, held in September 2010. Neotropical primates (New World monkeys), with their smaller size, faster maturation, and shorter lifespans than Old World monkeys, are efficient models and present unique opportunities for studying ...

Endometrial Collagen in Woolly Monkey (Lagothrix l. poeppiggi) and the Uakari (Cacajao calvus). [PDF]

open access: yesJ Med Primatol
ABSTRACT Introduction This study microscopically characterizes collagen changes and their relationship with endometrial architecture in two Neotropical primates. Methods Uterine fragments from six Lagothrix l. poeppigii and six Cacajao calvus in different reproductive phases were histologically processed using Picrosirius Red staining.

Rates of agonism among female primates: a cross-taxon perspective [PDF]

open access: yes, 2013
Agonism is common in group-living animals, shaping dominance relationships and ultimately impacting individual tness. Rates of agonism vary considerably among taxa, however, and explaining this variation has been central in ecological models of female ...

Sexual dimorphism in the loud calls of Azara’s owl monkeys (Aotus azarae): evidence of sexual selection? [PDF]

open access: yes, 2019
Primates use different types of vocalizations in a variety of contexts. Some of the most studied types have been the long distance or loud calls. These vocalizations have been associated with mate defense, mate attraction, and resource defense, and it ...
