Effect of polymorphic colour vision for fruit detection in the spider monkey Ateles geoffroyi, and its implications for the maintenance of polymorphic colour vision in platyrrhine monkeys [PDF]

, 2004
Most platyrrhine monkeys have an X-linked tri-allelic polymorphism for medium and long wavelength (M/L) sensitive cone photopigments. These pigments' sensitivity maxima (λmax) range from 535 to 562 nm.

Edge effects and social behavior in three platyrrhines. [PDF]

Am J Primatol
Abstract Social behavior is a key adaptation for group‐living primates. It is important to assess changes to social behavior in human‐impacted landscape zones to better understand the impact of anthropogenic disturbance on primate species. We investigated social behavior rate and type in three species of platyrrhines across 100 m anthropogenic edge and

Environmental factors associated With Toxoplasma gondii Exposure in Neotropical Primates of Costa Rica

Frontiers in Veterinary Science, 2020
The apicomplexan parasite Toxoplasma gondii (T. gondii) has been found in more than 350 species of homoeothermic vertebrates in diverse climates and geographic areas. In most animals, T. gondii produces mild or asymptomatic infection.

Fruit Availability and Maternal Energy Expenditure Associated With Infant Independence in an Arboreal Primate (Colobus angolensis ruwenzorii). [PDF]

Am J Primatol
Infant being handled by mother. ABSTRACT A range of ecological and social factors have been shown to affect early‐life behaviour in mammals. Primate infants are altricial and thus unable to move independently at birth. As a result, infants in some species are continuously held or carried (handled) by their mother or another caregiver (allomother ...

Fruit scent and observer colour vision shape food-selection strategies in wild capuchin monkeys [PDF]

, 2019
The senses play critical roles in helping animals evaluate foods, including fruits that can change both in colour and scent during ripening to attract frugivores.

Differential impact of severe drought on infant mortality in two sympatric neotropical primates [PDF]

Royal Society Open Science, 2020
Extreme climate events can have important consequences for the dynamics of natural populations, and severe droughts are predicted to become more common and intense due to climate change.
