Bimanual Coordination and Right‐Hand Bias in Extractive Foraging by Wild Sapajus libidinosus

open access: yesAmerican Journal of Primatology, Volume 88, Issue 5, May 2026.
Wild Sapajus libidinosus exhibit a significant preference at the population level for using their right‐hand fingers to extract nut kernels when employing bimanual coordination. ABSTRACT Bimanual coordination is considered a crucial factor in the evolution of manual lateralization.

Hominoid‐specific calretinin‐immunopositivity of the optic radiation (geniculocalcarine tract)

open access: yesThe Anatomical Record, Volume 309, Issue 5, Page 1343-1367, May 2026.
Calretinin‐immunostained coronal section through the primary (V1) and extrastriate (ExSt) cortex of the lar gibbon. Note that the optic radiation (OR) is strongly calretinin‐immunoreactive. This calretinin‐immunopositivity of the OR distinguishes the Hominoidea from other primates in terms of the neurochemistry of the OR.

Local Knowledge and Human–Wildlife Conflict in the Conservation of the Harpy Eagle (Harpia harpyja) in Its Main Refuge in the Atlantic Forest

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
The Harpy Eagle (Harpia harpyja), a top predator of Neotropical forests, faces severe threats across its range, including in the Atlantic Forest. Using 50 years of occurrence records, including nests and multiple age classes, we document the species' persistence in one of its last reproductive refuges while revealing ongoing human–wildlife conflicts ...
