Dietary ethanol ingestion by free-ranging spider monkeys (Ateles geoffroyi). [PDF]
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]
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 (<i>Ateles geoffroyi</i>). [PDF]
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 ...

Salivary response of Geoffroy's spider monkeys (<i>Ateles geoffroyi</i>) to consumption of plant secondary metabolites. [PDF]
Geoffroy’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 ...

Gestural communication in wild spider monkeys (Ateles geoffroyi). [PDF]
Gestures 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).

Seasonal Changes in Socio-Spatial Structure in a Group of Free-Living Spider Monkeys (Ateles geoffroyi). [PDF]
Ecological and social factors influence individual movement and group membership decisions, which ultimately determine how animal groups adjust their behavior in spatially and temporally heterogeneous environments.

The ability of captive spider monkeys, Ateles geoffroyi, to visually discriminate between different sizes of food and of non-edible objects. [PDF]
Field 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 ...

Serial visual reversal learning in captive black-handed spider monkeys, Ateles geoffroyi. [PDF]
Recent 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)

Alveolar Echinococcosis Infection in a Monkey (Ateles geoffroyi) In Mashhad, Iran. [PDF]
Alveolar echinococcosis (AE), which is caused by ingestion of eggs of the fox tapeworm Echinococcus multilocularis, is the most potentially lethal parasitic infection because of its tendency to invade and proliferate in the liver and the difficulty in ...
