Feeding in Forest Chimpanzees: Do Food Type and Canopy Location Predict Positional Behavior?

American Journal of Biological Anthropology, Volume 189, Issue 2, February 2026.
Ngogo chimpanzees from Kibale National Park, Uganda use versatile postures, like suspension, more when eating leaves than other foods. However, in the terminal canopy, eating fruit is most associated with versatility. Food type and availability, in different combinations, produce similar behaviors.

Patrones de actividad y comportamiento social de Cebus Albifrons Versicolor en un fragmento de bosque en el Magdalena Medio [PDF]

, 2013
Los monos cariblancos (Cebus albifrons versicolor) son endémicos de Colombia con una distribución restringida a bosques de los valles Interandinos. Al igual que las demás especies del género Cebus, estos primates tienen una organización social jerárquica

Forest structure and connectivity drive the functional recovery of seed rain

Journal of Ecology, Volume 114, Issue 2, February 2026.
Local forest structure and landscape‐scale connectivity shape distinct but complementary pathways of the functional recovery of seed rain in tropical forests. Structural complexity promotes functionally diverse plant–frugivore interactions locally, while connectivity facilitates the arrival of late‐successional seeds from external sources.

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

Revista 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 ...

Vigilance in wild Thomas's langurs (Presbytis thomasi): the importance of infanticide risk [PDF]

, 1998
This study examines vigilance as a behavioural indicator of the importance of infanticide risk by com- paring the infanticide avoidance hypothesis with the predation avoidance and mate defence hypotheses for wild Thomas's langurs (Presbytis thomasi ...

Field Anesthesia and Health Assessment of Free-ranging Cebus capucinus in Panama [PDF]

International Journal of Primatology, 2009
Health and disease are critical factors for understanding primate evolution and for developing effective conservation and management strategies. However, comprehensive health assessments of wild primate populations are rare, in part because of the difficulty and risk of chemically immobilizing subjects to obtain the necessary biological samples.

Optimal foraging can drive emergent initiator‐follower dynamics in social groups

Oikos, Volume 2026, Issue 1, January 2026.
Deciding when and where to move is a challenge for group‐living animals as differences in preferences must be resolved for the group to maintain cohesion. In many species, consensus is reached through shared decision‐making, whereby group members initiate group movements by stopping foraging and making directed movements away from a feeding source. Yet,

Nocturnal activity by the primarily diurnal Central American agouti (Dasyprocta punctata) in relation to environmental conditions, resource abundance and predation risk [PDF]

, 2009
An animal's fitness is in part based on its ability to manage the inherent risks (foraging costs, predation, exposure to disease) with the benefits (resource gain, access to mates, social interactions) of activity (Abrams 1991, Altizer et al. 2003, Lima &
