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

There is no other monkey in the mirror for spider monkeys (Ateles geoffroyi). [PDF]

Journal of Comparative Psychology, 2020
Mirror self-recognition (MSR), usually considered a marker of self-awareness, occurs in several species and may reflect a capacity that has evolved in small incremental steps. In line with research on human development and building on previous research adopting a gradualist framework, we categorized the initial mirror responses of naïve spider monkeys (

Individual variability in visual recognition memory of black-handed spider monkeys (Ateles geoffroyi)

International Journal of Comparative Psychology, 2022
Recognition memory is an ability that allows animals to respond differentially to stimuli, individuals, or situations experienced in the past and plays an important role in foraging and social behavior.

Retrotransposon mapping in spider monkey genomes of the family Atelidae (Platyrrhini, Primates) shows a high level of LINE-1 amplification

Journal of Biological Research, 2022
To investigate the distribution of LINE-1 repeat sequences, a LINE-1 probe was Fluorescence In Situ Hybridized (FISH) on the chromosomes of Ateles geoffroyi and Ateles fusciceps (Atelidae); a LINE-1 probe was also mapped on Cebuella pygmaea (Cebidae ...

Plant Diversity in the Diet of Costa Rican Primates in Contrasting Habitats: A Meta-Analysis

Diversity, 2023
In human-modified tropical landscapes, the survival of arboreal vertebrates, particularly primates, depends on their plant dietary diversity. Here, we assess the diversity of plants included in the diet of Costa Rican non-human primates, CR-NHP (i.e ...

Flexible Foraging Strategies of Hainan Gibbons (<i>Nomascus hainanus</i>) in Response to Food Variation Across Contrasting Habitats. [PDF]

Ecol Evol
This study, based on long‐term field monitoring and conservation efforts of Hainan gibbons, analyzed their foraging movement strategies across different spatial contexts (Groups C and E) and temporal periods (the fruit‐eating period and the mixed‐diet period).

Monkey Meltdowns: Do Tantrums Influence Maternal Investment in Bearded Capuchin Monkeys? [PDF]

Dev Psychobiol
ABSTRACT Tantrums are widely discussed in human development literature and are typically defined as displays of frustration or anger. In behavioral ecology, they are hypothesized to function as a strategy for securing greater maternal investment. Infant primates often exhibit tantrums when their attempts to obtain maternal care are rejected.

Multifocal Oral Epithelial Hyperplasia Associated With Papillomavirus Infection in a Road Killed Brown Howler Monkey (Alouatta guariba clamitans). [PDF]

J Med Primatol
ABSTRACT A free‐ranging road‐killed brown howler monkey (Alouatta guariba clamitans) presented multiple mucosal‐colored papules and plaques on oral mucosa. Pathological evaluation confirmed the diagnosis of epithelial hyperplasia with koilocytosis.
