Caudal Vertebral Body Articular Surface Morphology Correlates with Functional Tail Use in Anthropoid Primates [PDF]
, 2014 Prehensile tails, capable of suspending the entire body weight of an animal, have evolved in parallel in New World monkeys (Platyrrhini): once in the Atelinae (Alouatta, Ateles, Brachyteles, Lagothrix), and once in the Cebinae (Cebus, Sapajus ...

Clarifying the Cryptic Host Specificity of Blastocystis spp. Isolates from Alouatta palliata and A. pigra Howler Monkeys. [PDF]
PLoS ONE, 2017 Although the presence of cryptic host specificity has been documented in Blastocystis, differences in infection rates and high genetic polymorphism within and between populations of some subtypes (ST) have impeded the clarification of the generalist or ...

Mechanical Defenses in Leaves Eaten by Costa Rican Howling Monkeys (Alouatta palliata) [PDF]
American Journal of Physical Anthropology, 2005 Primate species often eat foods of different physical properties. This may have implications for tooth structure and wear in those species. The purpose of this study was to examine the mechanical defenses of leaves eaten by Alouatta palliata from different social groups at Hacienda La Pacifica in Costa Rica.

Comparison of forest regeneration in two sites with different primate abundances in Northwestern Ecuador [PDF]
, 2016 There is increasing evidence that large-bodied primates play important roles as seed dispersers and in the maintenance of tree diversity in forest ecosystems. In this study we compared forest regeneration at two sites with differing primate abundances in
