A suture in time: The ontogeny of cranial suture morphology in mammals

Journal of Anatomy, Volume 248, Issue 3, Page 501-516, March 2026.
Mammal cranial sutures are important indicators of the biomechanical and developmental pressures acting upon the skull. Across three prominent sutures dividing the vault of the mammalian skull, divergent patterns emerge both taxonomically and developmentally.

Contexts of Anointing Behavior in a Group of Blond Capuchin Monkeys (Sapajus flavius) Inhabiting an Atlantic Forest Fragment

American Journal of Primatology, Volume 88, Issue 1, January 2026.
Wild blond capuchin anoints with millipede species that secrete a chemical capable of repelling ectoparasites, suggesting a self‐medicative function. Social and solitary anointing bouts occurred at similar frequencies, but with greater engagement by adult males, indicating that anointing is a multifunctional behavior.

Morphological Changes in Direct Pathway Striatal Neurons in a Rat Model of Tardive Dyskinesia

Movement Disorders, Volume 41, Issue 1, Page 234-240, January 2026.
Abstract Background Tardive dyskinesia (TD) and drug‐induced parkinsonism (DIP) arise from prolonged dopamine antagonist use. Although D2 receptor hypersensitivity in the indirect pathway is a proposed mechanism, the role of the direct pathway remains unclear.

Heterochromatin and chromosome evolution: a FISH probe of Cebus apella paraguayanus (Primate: Platyrrhini) developed by chromosome microdissection.

Genetics and molecular research : GMR, 2006
Neotropical Primate karyotypes are highly variable, particularly in the heterochromatic regions, not only regarding the amount of heterochromatin, but also the composition. G and C banding and FISH techniques provide useful information to characterize interspecific relationships.

An Observation of Coordinated Collaboration in Wild Brown Skua (Stercorarius antarcticus)

Ecology and Evolution, Volume 15, Issue 12, December 2025.
We present the first video evidence of cooperative food processing in wild brown skuas (Stercorarius antarcticus) on the Antarctic Peninsula. Our observations show that pairs coordinated their actions over space and time, consistent with actively coordinated collaboration.
