Successful Reintegration of a Golden‐Headed Lion Tamarin (Leontopithecus chrysomelas) Sheds Light on Management of This Endangered Species—Case Report [PDF]

Journal of Medical Primatology, Volume 55, Issue 1, February 2026.
ABSTRACT A male Leontopithecus chrysomelas rescued after being found in a road in Bahia, Brazil, received clinical treatment and was successfully reintegrated into its native group after 49 days. Post‐release monitoring confirmed normal behavior, highlighting the importance of coordinated field–captive management for endangered primate rehabilitation.

Vocalizations Reveal Species Differences in Endangered Lion Tamarins (Primates, Callitrichidae) [PDF]

American Journal of Primatology, Volume 88, Issue 1, January 2026.
Spectral parameters of vocalizations distinguish lion tamarin species. Peak frequency, center frequency, and frequency at 5% and 95% were the most informative measures for separating species, with the trill being the vocalization that showed the most differences, and Leontopithecus caissara being the most distinct species of all.

Molecular Detection of Toxoplasma gondii in Enclosures of African Primates (Papio papio and Papio hamadryas) at the Municipal Zoo of Bauru, São Paulo State, Brazil [PDF]

Journal of Medical Primatology, Volume 55, Issue 3, June 2026.
ABSTRACT Toxoplasmosis is one of the most prevalent parasitic infections in animals and humans worldwide, attracting the attention of many researchers who, in recent decades, have identified the sources of Toxoplasma gondii infections to optimize the adoption of preventive measures. In previous studies, it has been found that humans are infected mainly

Short‐Term Puzzle Feeder Enrichment Increases Food Engagement but Not Stress‐Related Behaviour in Captive Golden‐Headed Lion Tamarins [PDF]

Ecology and Evolution, Volume 16, Issue 4, April 2026.
Food puzzles significantly increased food engagement time in captive golden‐headed lion tamarins (Leontopithecus chrysomelas), with individuals spending three times longer foraging compared to standard food bowls. Grooming and activity levels showed no short‐term changes, though patterns varied across enclosures. These findings highlight puzzle feeders

Validation of Immunoassays for Total Thyroxine and Free Thyroxine and Age and Sex‐Related Variation in Thyroid Hormone Serum Concentrations in Orangutans (Pongo sp.) [PDF]

Journal of Medical Primatology, Volume 55, Issue 3, June 2026.
ABSTRACT Background Thyroid disease is reported in orangutans, but to properly diagnose and manage these disorders, reference intervals for circulating thyroid hormones are needed. Methods Commercial immunoassay kits for total thyroxine (TT4) and free thyroxine (FT4) were validated for use in orangutans (Pongo spp.).

Evolutionary morphology of the haplorhine hamate

The Anatomical Record, EarlyView.
Abstract Primates adopt a variety of hand postures during an impressive diversity of locomotor and manipulative behaviors. Morphological research has found that elements of the hand skeleton, such as the hamate, hold key information for inferring hand use and locomotor kinematics in extinct species.

Humans and platyrrhines share a pattern of articular variance

The Anatomical Record, EarlyView.
Abstract Previous work has identified a pattern of articular shape variation in modern human limb joints, in which convex joint surfaces exhibit constrained variance relative to their more variable concave conarticulars. This pattern is notable given that joint morphogenesis is influenced by local biomechanical environments, which vary substantially ...

Foraging and movement flexibility shape seed dispersal by an arboreal primate in a modified landscape

Oikos, EarlyView.
As habitats change, the effectiveness of animal‐mediated seed dispersal increasingly depends on animal responses to altered structure and resources. With habitat loss and degradation accelerating across the tropics, understanding how dispersers' foraging behavior and movement influence seed removal and deposition is critical to promoting forest ...

Taxon, Arboreality, Sex, and Season—Factors Influencing Gastrointestinal Parasite Occurrence in Zoo‐Housed Non‐Human Primates

Zoo Biology, EarlyView.
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.

Labiolingual thickness and cross‐sectional area in callitrichid incisors

Journal of Anatomy, EarlyView.
Many primates gouge to extract gums or saps from trees as part of their diet. Gouging callitrichid monkeys are characterized by lower incisors that are labiolingually thicker than non‐gougers, however, their incisors are not any larger in cross‐section. This difference may provide key insight into the gouging behavior of fossil primates.
