Kin structure and parallel dispersal in the black-and-gold howler monkey Alouatta caraya (Platyrrhini, Atelidae)

Genetics and Molecular Research, 2013
We here investigated the kin structure and pattern of dispersal in the black-and-gold howler monkey (Alouatta caraya, Platyrrhini, Atelidae) based on genotype differences at nine microsatellite loci of 48 individuals from eight social groups along the riparian forest of the Tocantins River, Brazil.

Population genetics and evolutionary history of the black howler monkey Alouatta pigra and hybrid populations in Mexico

Frontiers in Ecology and Evolution
Genetic diversity is of prime importance for biological diversity and for the long-term conservation and survival of species and populations. The conservation of hybrid individuals originating from natural hybridization is still controversial; nearly ...

The prion protein and New World primate phylogeny [PDF]

, 2004
The PrPC prion protein contains 250 amino acids with some variation among species and is expressed in several cell types. PrPC is converted to PrPSc by a post-translational process in which it acquires amino acid sequences of three-dimensional ...

Assessing the gut microbiome and the influence of host genetics on a critically endangered primate, the northern muriqui (Brachyteles hypoxanthus)

Environmental DNA, Volume 6, Issue 3, May–June 2024.
Analyses of the microbiome of the critically endangered muriqui revealed the importance of host genetics on the microbiome and suggested that social groups, despite being isolated by environmental barriers, host a similar microbiome composition. Abstract The Northern muriqui (Brachyteles hypoxanthus) is one of the world's most critically endangered ...

A comparative study of eleven protein systems in tamarins, genus Saguinus (Platyrrhini, Callitrichinae) [PDF]

, 1997
The genetic variability of six tamarin taxa, genus Saguinus, was analyzed comparatively using protein data from eleven systems coded by 15 loci. S. fuscicollis weddelli and S. midas midas were the most polymorphic taxa, and S. bicolor the least.
