Site fidelity in space use by spider monkeys (Ateles geoffroyi) in the Yucatan peninsula, Mexico. [PDF]
PLoS ONE, 2013 Animal home ranges may vary little in their size and location in the short term but nevertheless show more variability in the long term. We evaluated the degree of site fidelity of two groups of spider monkeys (Ateles geoffroyi) over a 10- and 13-year ...

Dietary ethanol ingestion by free-ranging spider monkeys (Ateles geoffroyi) [PDF]
Royal Society Open Science, 2022 Ethanol within ripe and over-ripe fruit is produced naturally through the metabolic activity of fermentative yeasts. As a consequence, frugivorous animals may chronically consume ethanol as part of their routine diet, although direct measurements of such

Yawning and scratching contagion in wild spider monkeys (Ateles geoffroyi) [PDF]
Scientific Reports, 2023 Behavioural contagion is a widespread phenomenon in animal species, which is thought to promote coordination and group cohesion. Among non-human primates, however, there is no evidence of behavioural contagion in Platyrrhines (i.e.

Influence of tannic acid concentration on the physicochemical characteristics of saliva of spider monkeys (Ateles geoffroyi) [PDF]
PeerJ, 2022 Tannins are a chemical defense mechanism of plants consumed by herbivores. Variations in salivary physicochemical characteristics such as pH, total protein concentration (TP), and presence of proline-rich proteins (PRPs) in animals have been reported as ...

Gestural communication in wild spider monkeys (Ateles geoffroyi) [PDF]
Animal CognitionGestures play a central role in the communication systems of several animal families, including primates. In this study, we provide a first assessment of the gestural systems of a Platyrrhine species, Geoffroy’s spider monkeys (Ateles geoffroyi).

Population genetic patterns among social groups of the endangered Central American spider monkey (Ateles geoffroyi) in a human-dominated landscape. [PDF]
Ecol Evol, 2013 Spider monkeys (Genus: Ateles) are a widespread Neotropical primate with a highly plastic socioecological strategy. However, the Central American species, Ateles geoffroyi, was recently re-listed as endangered due to the accelerated loss of forest across

The ability of captive spider monkeys, Ateles geoffroyi, to visually discriminate between different sizes of food and of non-edible objects [PDF]
Scientific ReportsField studies suggest that the size of potential food items plays an important role in the food selection behavior of nonhuman primates. However, there is only limited knowledge about how good primates are at visually discriminating between the size of ...

Maternal Investment Fosters Male but Not Female Social Interactions with Other Group Members in Immature Wild Spider Monkeys (Ateles geoffroyi) [PDF]
Animals, 2023 In several species, individuals form long-lasting social relationships with other group members, which provide them with important fitness benefits. In primates, patterns of social relationships are known to differ between sexes, but little is known ...

Salivary response of Geoffroy’s spider monkeys (Ateles geoffroyi) to consumption of plant secondary metabolites [PDF]
PeerJGeoffroy’s spider monkeys (Ateles geoffroyi) can modulate the acidity-alkalinity (pH) and salivary expression of total proteins (TP) and proline-rich proteins (PRPs) depending on the concentration of tannins in their diet, helping to counteract negative ...

Serial visual reversal learning in captive black-handed spider monkeys, Ateles geoffroyi [PDF]
Animal CognitionRecent research suggests that socio-ecological factors such as dietary specialization and social complexity may be drivers of advanced cognitive skills among primates. Therefore, we assessed the ability of 12 black-handed spider monkeys (Ateles geoffroyi)
