First Molecular Characterization of the Zoonotic Parasite Balantioides coli in Brachyteles hypoxanthus Wied, 1820 (Primate: Atelidae) in Brazil. [PDF]

J Med Primatol
ABSTRACT Fecal samples from seven individuals kept in semi‐captivity in Minas Gerais were subjected to microscopic and molecular parasitological techniques. Balantioides coli was identified in all samples with a predominance of an atypical variant. This is the first molecular characterization of B. coli in Brachyteles hypoxanthus in Brazil.

Anatomical Description of the Main Gyri and Sulci of the Telencephalon of Alouatta belzebul. [PDF]

Anat Histol Embryol
ABSTRACT The Alouatta belzebul is a species of howler monkey, of the Atelidae family and genus Alouatta. It is endemic in Brazil and has a separate geographic distribution, with two populations occurring: in the Amazon and in the Atlantic Forest on the coast of Northeast Brazil. The species is classified as ‘vulnerable’, and this is mainly justified by

Female Reproductive System Neoplasms in Neotropical Primates. [PDF]

J Med Primatol
ABSTRACT Background There are no previous descriptions of the prevalence of spontaneous female reproductive neoplasms in neotropical primates. Methods A 6‐year study of pathological records from the Anatomy Pathology Sector from the Federal Rural University of Rio de Janeiro (SAP/UFRuralRJ) was conducted.

Mitochondrial DNA for Phylogeny Building: Assessing Individual and Grouped mtGenes as Proxies for the mtGenome in Platyrrhines. [PDF]

Am J Primatol
ABSTRACT Phylogenetic trees are analytic tools used in primate studies to elucidate evolutionary relationships. Because of its relative ease to sequence and rapid evolution compared to nuclear genomes, mitochondrial DNA is frequently used for phylogeny building. This project evaluated the effectiveness of using individual or grouped mitochondrial genes

Present and Future: Using Ecological Niche Modeling to Understand the Conservation Status of Alouatta caraya (Primates, Atelidae) and Promote Its Protection. [PDF]

Am J Primatol
Free‐living Alouatta caraya: the male (top left) and his females (bottom left). We used ecological niche modeling to assess the species' climate suitability both now and in future projections. Between now and 2030, there is a 31% reduction in distribution.

Lagothrix flavicauda(Primates: Atelidae)

Mammalian Species, 2021
AbstractLagothrix flavicauda (Humboldt, 1812), commonly known as the yellow-tailed woolly monkey, is one of the largest New World primates. Its diet is based on fruits and leaves, and occasionally flowers, buds, epiphyte roots, invertebrates, and some vertebrates.

Polymorphism of visual pigment genes in the muriqui (Primates, Atelidae) [PDF]

Molecular Ecology, 2005
AbstractColour vision varies within the family Atelidae (Primates, Platyrrhini), which consists of four genera with the following cladistic relationship: {Alouatta[Ateles(LagothrixandBrachyteles)]}. Spider monkeys (Ateles) and woolly monkeys (Lagothrix) are characteristic of platyrrhine monkeys in possessing a colour vision polymorphism.

Photopigments and colour vision in New World monkeys from the family Atelidae [PDF]

Proceedings of the Royal Society of London. Series B: Biological Sciences, 2001
Most New World monkeys have an X-chromosome opsin gene polymorphism that produces a variety of different colour vision phenotypes. Howler monkeys (Alouatta), one of the four genera in the family Atelidae lack this polymorphism. Instead, they have acquired uniform trichromatic colour vision similar to that of Old World monkeys, apes and people through ...
