Modeling the Searching Behavior of Social Monkeys

open access: yes, 2003
We discuss various features of the trajectories of spider monkeys looking for food in a tropical forest, as observed recently in an extensive {\it in situ} study. Some of the features observed can be interpreted as the result of social interactions.

Like Father, like son: assessment of the morphological affinities of a.l. 288-1 (a. afarensis), sts 7 (a. africanus) and omo 119-73-2718 (australopithecus sp.) through a three-dimensional shape analysis of the shoulder joint [PDF]

open access: yes, 2016
The postcranial evidence for the Australopithecus genus indicates that australopiths were able bipeds; however, the morphology of the forelimbs and particularly that of the shoulder girdle suggests that they were partially adapted to an arboreal ...

Ecology, diet, and social patterning in Old and New World primates [PDF]

open access: yes, 1975
For a given primate species, the groups are more or less important not only in relation to their biomass and available food but also according to particular conditions of the environment (for example scattering of vegetal food species).

River crossings by Ateles geoffroyi and Alouatta pigra in southern Mexico: A preliminary report Habilidad para cruzar ríos en Ateles geoffroyi y Alouatta pigra en el sur de México: Un reporte preliminar

open access: yesRevista Chilena de Historia Natural, 2010
During a nine month field study, we assess the ability of spider (Ateles geoffroyi) and howler (Alouatta pigra) monkeys to cross a large Mesoamerican river, and if this behavior is related to deforestation and/or human population size on the disturbed ...

New World monkeys: distribution and origin of South American monkeys [PDF]

open access: yes, 2018
Majmuni Novog svijeta (Platyrrhini) primati su koji žive u tropskim šumama Južne i Srednje Amerike. Od majmuna Starog svijeta (Catarrhini) razlikuju se anatomijom i načinom života. Smatra se da su se ove dvije linije majmuna odvojile prije oko 35 mil.

Variation in ligand responses of the bitter taste receptors TAS2R1 and TAS2R4 among New World monkeys. [PDF]

open access: yes
BACKGROUND: New World monkeys (NWMs) are unique in that they exhibit remarkable interspecific variation in color vision and feeding behavior, making them an excellent model for studying sensory ecology.
