摘要: Both laboratory and field data demonstrate that marmosets gouge trees with wide jaw gapes to elicit exudate flow. Tree gouging distinguishes from other platyrrhines presents a natural experiment for studying the morphological consequences of this derived feeding behavior. We utilize comparative histomorphometrics determine whether loading TMJ at impacts articular cartilage form in two habitual species, common (Callitrix jacchus) pygmy (Cebuella pygmaea), compared nongouging cotton-top tamarins (Saguinus oedipus) squirrel monkeys (Saimiri sciureus). Our histological comparisons found no difference along posterior condyle between species. Alternatively, anterior glenoid species was relatively larger deeper These findings suggest possesses improved load resistance ability points mosaic nature functional responses tree marmoset masticatory apparatus.
