Neopterin as a Tool for Primate Ecoimmunology: Current Knowledge, Practical Application, and New Directions From Captivity to the Wild

American Journal of Primatology, Volume 87, Issue 10, October 2025.
Neopterin is a sensitive and specific biomarker of intracellular pathogen infection and chronic inflammation, and affected by environmental, life‐history, and sex‐contextual factors. This review offers best‐practice guidelines and practical advice on sample collection, storage, and analysis in primates when used for ecoimmunological conservation and ...

Does Knowledge of the Partner's Need Affect Food Sharing in Tufted Capuchin Monkeys?

American Journal of Primatology, Volume 87, Issue 10, October 2025.
Capuchin monkeys were given the possibility to share food after having or not having seen a partner eat. Neither having seen the partner eat nor the quality of the food eaten by the partner had any effect on the monkeys' willingness to share part of their food.

Mechanical isolation of capuchin monkey (Cebus apella) preantral ovarian follicles

Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2003
The aim of this study was to adapt a mechanical procedure for the isolation of intact preantral follicles from Cebus apella ovaries. The interval effect of serial sections of the tissue chopper was tested on a number of preantral follicles isolated from ...

Look past the cooperative eye hypothesis: reconsidering the evolution of human eye appearance

Biological Reviews, Volume 100, Issue 5, Page 2038-2054, October 2025.
ABSTRACT The external appearance of the human eye has been prominently linked to the evolution of complex sociocognitive functions in our species. The cooperative eye hypothesis (CEH) proposes that human eyeballs, with their weakly expressed conjunctival and scleral pigmentation, are uniquely conspicuous and evolved under selective pressures to behave ...

Absence of Blood Chimerism in Twin Goeldi's Monkeys (Callimico goeldii): Implications for Interpreting Callitrichid Phylogeny

American Journal of Primatology, Volume 87, Issue 9, September 2025.
All Callitrichidae have twins who are chimeras, but Callimico has singletons. We examined evidence of blood chimerism in the only known surviving Callimico twins, and found that they were non‐chimeric. This represents the first report of the absence of blood chimerism in twins of any callitrichid species.
