Gut microbiota signatures of the three Mexican primate species, including hybrid populations. [PDF]
PLoS ONEDiversity of the gut microbiota has proven to be related with host physiology, health and behavior, influencing host ecology and evolution. Gut microbial community relationships often recapitulate primate phylogeny, suggesting phylosymbiotic associations.

Variation in the extraction efficiency of estradiol and progesterone in moist and lyiphilized feces of the black howler monkey (Alouatta pigra): alternative methods [PDF]
Frontiers in Physiology, 2011 several fecal steroid extraction techniques have been developed to measure the ovary function in different species of mammals. However, regardless of the method of extraction and the sample type chosen, is has been observed that they can yield results ...

Histopathological Changes and Immune Response Profile in the Brains of Non-Human Primates Naturally Infected with Yellow Fever Virus [PDF]
VirusesIn the history of yellow fever (YF) outbreaks in Brazil, howler monkeys (Alouatta sp.) and marmosets (Callithrix sp.) have been among the most affected genera, exhibiting significant hepatic injuries similar to those seen in humans.

High infection prevalences by Trypanosoma minasense in non-human primates from the Southeast region of Brazil [PDF]
Scientific ReportsNon-human primates (NHPs) are reported as exclusive hosts of Trypanosoma minasense, whose transmission cycle remains unknown. We investigated trypanosomatid infections in 194 NHPs of nine species from the Brazilian Southeast region.

Ganglion cell and displaced amacrine cell density distribution in the retina of the howler monkey (Alouatta caraya). [PDF]
PLoS ONE, 2014 Unlike all other New World (platyrrine) monkeys, both male and female howler monkeys (Alouatta sp.) are obligatory trichromats. In all other platyrrines, only females can be trichromats, while males are always dichromats, as determined by multiple ...

Alouatta trichromatic color vision: cone spectra and physiological responses studied with microspectrophotometry and single unit retinal electrophysiology. [PDF]
PLoS ONE, 2014 The howler monkeys (Alouatta sp.) are the only New World primates to exhibit routine trichromacy. Both males and females have three cone photopigments. However, in contrast to Old World monkeys, Alouatta has a locus control region upstream of each opsin ...

Pinworms of the red howler monkey (Alouatta seniculus) in Colombia. Gathering the pieces of the pinworm-primate puzzle [PDF]
, 2020 Pinworms of primates are believed to be highly host specific parasites, forming co-evolutionary associations with their hosts. In order to assess the strength and reach of such evolutionary links, we need to have a broad understanding of the pinworm ...

Primate populations in continuous forest and forest fragments in Central Amazonia [PDF]
Acta Amazonica, 1988 Population densities of six primate species (Saguinus midas, Pithecia pithecia, Cebus apella, Chiropotes satanas, Alouatta seniculus and Ateles paniscus) were estimated in continuous forest and in isolated reserves (one of 100 ha and four of 10 ha ...
