Edge effects and social behavior in three platyrrhines

American Journal of Primatology, Volume 87, Issue 1, January 2025.
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

Drinking from Arboreal Water Sources by Mantled Howling Monkeys (Alouatta palliata Gray) [PDF]

Folia Primatologica, 1978
Mantled howling monkeys (Alouatta palliala Gray) were observed to drink from arboreal water sources during the wet season but not during the 5 month dry season. The lack of drinking in the dry season is attributed to seasonal differences in their activity patterns and food selection, the water content of the food, and the absence of plant secondary ...

Monkeys Swimming Across Rivers Refine Questions About the Riverine Barrier Hypothesis

American Journal of Primatology, Volume 87, Issue 1, January 2025.
Alouatta macconnelli river crossing, Guyana. ABSTRACT The Riverine Barrier Hypothesis posits that species distributions are limited by large rivers acting as geographical barriers. Accordingly, large rivers have long been thought to be a major driver of the extensive speciation and high levels of biodiversity among platyrrhine primates in South and ...
