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

Sources of Variation in Fecal Haptoglobin in a Population of Wild Capuchin Monkeys (Cebus imitator). [PDF]

Am J Primatol
Fecal haptoglobin values show significant seasonal variation in wild capuchin monkeys. Values are highest, and most variable in the early‐mid dry season, when fruit is typically scarce and water sources are standing pools, which can accumulate pathogens.

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.

Genomic Insights Into Host Shifts Between <i>Plasmodium vivax</i> and <i>Plasmodium simium</i> in Latin America. [PDF]

Evol Appl
ABSTRACT Malaria in Latin America is largely caused by Plasmodium vivax, but the closely related monkey parasite Plasmodium simium has recently been observed in humans, thus raising new public health concerns. By screening 719 monkey samples from five Latin America countries, we identified 23 Plasmodium‐positives.

A Historical Reassessment of the Authorship Year of Brachyteles arachnoides (Primates: Atelidae). [PDF]

Am J Primatol
Key historical milestones in the taxonomy of Brachyteles arachnoides. It begins with Browne's (1756) early depiction of Simia 2, “The Four‐fingered Monkey”, in Jamaica, followed by Edwards' (1764) account of a brown four‐fingered monkey in the streets of London.

Prevalence of Plasmodium parasites in non-human primates and mosquitoes in areas with different degrees of fragmentation in Colombia

Malaria Journal, 2019
Background Parasites from the genus Plasmodium, the aetiological agent of malaria in humans, can also infect non-human primates (NHP), increasing the potential risk of zoonotic transmission with its associated global public health concerns.
