Abduction and potential case of predation of an infant howler monkey (Alouatta guariba clamitans) by a tufted capuchin monkey (Sapajus nigritus) [PDF]
, 2017 The likelihood of interspecific interactions between wild primates is particularly high for species with overlapping territories. The sharing of the same or similar ecological niches can result in competition for space or resources, which can lead to ...

International Journal of Acarology, 2002 Abstract Preliminary results of a study on ectoparasites of Costa Rican monkeys are presented. Thirty six mantled howler monkeys (Alouatta palliata Gray, 1849) and 3 capuchin monkeys (Cebus capucinus Linnaeus, 1758) from different zones of the country were examined for ectoparasites.

Superior cervical vertebrae of a Miocene hominoid and a Plio-Pleistocene hominid from southern Africa [PDF]
, 2000 The Miocene hominoid and Plio-Pleistocene hominid vertebral record is poor. In 1994, a complete atlas of a hominoid was found in breccia at Berg Aukas in Namibia. Its age was estimated to be middle Miocene (13 myr) on the basis of microfauna.

Behavioural Changes in Parenting Female Mantled Howler Monkeys (Alouatta palliata)
The University of Western Ontario Journal of Anthropology, 2012 Parenting in mantled howler monkeys (Alouatta palliata) requires a new set of energetic and behavioural demands. Because of constraints presented by the infant, as well as the increased energy requirements associated with mothering, parenting females need to change their activity patterns to ensure the successful upbringing of their offspring.
