Journal of Medical Primatology, Volume 55, Issue 4, August 2026.ABSTRACT A free‐ranging road‐killed brown howler monkey (Alouatta guariba clamitans) presented multiple mucosal‐colored papules and plaques on oral mucosa. Pathological evaluation confirmed the diagnosis of epithelial hyperplasia with koilocytosis.

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 ...

American Journal of Primatology, Volume 88, Issue 7, July 2026.Structural, functional, and evolutionary links between two behavioral by‐products (i.e., stone play and female‐to‐female mounting—FFM) and their putative corresponding behavioral adaptations (i.e., stone tool use and female‐to‐male mounting—FMM) in Balinese long‐tailed macaques and Japanese macaques.

Zoo Biology, Volume 45, Issue 4, Page 371-381, July/August 2026.ABSTRACT The emergence of anthelminthic resistance is a well‐documented phenomenon in livestock and companion animals. Given the scarcity of new antiparasitic drugs, the implementation of effective, holistic anthelminthic control strategies is critical to preserving the efficacy of existing treatments.

Do Social Conditions Affect Capuchin Monkeys’ (Cebus apella) Choices in a Quantity Judgment Task?
Frontiers in Psychology, 2012 Beran et al. (2012) reported that capuchin monkeys closely matched the performance of humans in a quantity judgment test in which information was incomplete but a judgment still had to be made.

Eye preferences in capuchin monkeys (Sapajus apella) [PDF]
Primates, 2016 This study explored whether capuchin monkey eye preferences differ systematically in response to stimuli of positive and negative valence. The ‘valence hypothesis’ proposes that the right hemisphere is more dominant for negative emotional processing and the left hemisphere is more dominant for positive emotional processing. Visual information from each

Non‐Invasive Measures of DNA Methylation Capture Molecular Aging in Wild Capuchin Monkeys
Molecular Ecology, Volume 35, Issue 14, July 2026.ABSTRACT Elucidating the socio‐ecological factors that shape patterns of aging in long‐lived vertebrates is of broad interest to evolutionary biologists, geroscientists, and ecologists. However, research on aging in wild populations still faces challenges due to the difficulty of measuring cellular hallmarks of aging non‐invasively and the difficulty ...

A Recessive oca2 Mutation Underlies Albinism in Xiphophorus Fish
Pigment Cell &Melanoma Research, Volume 39, Issue 4, July 2026.Genetic mapping of albino Xiphophorus hellerii showed that albinism is associated with a recessive oca2 variant. This variant leads to early termination of the Oca2 protein. This study identifies a novel model system to investigate conserved mechanisms of pigmentation biology.

Natural infection by Microsporum canis in a capuchin monkey
Ciência Rural: This paper described a case of a capuchin monkey (Sapajus libidinosus) with non-pruritic skin lesions. During the physical examination, multifocal areas of alopecia with crusts, erythema and scaling compatible with dermatophytosis were reported on the ...
