Assessing the Determinants of Platyrrhine Quadrupedal Gait Kinematics in an Ecological and Phylogenetic Framework

open access: yesAmerican Journal of Primatology, Volume 87, Issue 2, February 2025.
Results of redundancy analysis and variation partitioning reveal that phylogeny influences quadrupedal kinematics more strongly than do substrate characteristics in platyrrhines moving in their natural habitat. Callitrichines are maximally divergent from other taxa due to their preference for asymmetrical gaits, higher speeds and higher stride ...

Variation in Pubic Symphysis Fusion Across Primates: Implications for Obstetric Adaptation

open access: yesAmerican Journal of Biological Anthropology, Volume 186, Issue 2, February 2025.
Variation in the fusion of the pubic symphysis in primate pelves. ABSTRACT Objectives The unfused human pubic symphysis has been interpreted as an obstetric adaptation to facilitate the passage of a large‐brained baby through a relatively small, bipedally adapted pelvis.

Prevalence of fur mites (Acari: Atopomelidae) in non-human primates of Costa Rica

open access: yesRevista de Biología Tropical, 2009
Parasites have been investigated for some New World primates; however, very little is known about ectoparasites and specifically fur mites. In this study, Alouatta palliata, Cebus capucinus, Saimiri oerstedii, and Ateles geoffroyi monkeys from different ...

And Baby Makes Three: Postpartum Changes in Male–Female Affiliative Interactions in White‐Faced Capuchins

open access: yesAmerican Journal of Primatology, Volume 87, Issue 1, January 2025.
Photo by Nicholas Chapoy. Females and their new infants are of great interest to group members in white‐faced capuchins. ABSTRACT In group‐living primates, male investment in infants is highly variable. Previous research on polygynandrous primates found that male care of infants, whether direct or indirect, may be a means to increase offspring survival,

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.

Desarrollo de puentes aéreos para el desplazamiento seguro de monos en Costa Rica

open access: yesCiencias Ambientales
La mortalidad de los monos en Costa Rica se debe, en la mayoría de los casos, a factores antropogénicos, como la deforestación, la fragmentación de los bosques, la falta de conectividad arbórea y el desarrollo turístico en la mayoría de las zonas ...
