This study investigates how life cycle variations and ecological transitions affect the feeding musculature in salamanders.
Conducted dissections on the feeding system of 25 salamander species with varying life cycles and ecological strategies.
Measured muscle volume and physiological cross-sectional area (PCSA) of jaw and hyoid muscles.
Evaluated the relationship between ecological transitions and muscular architecture.
Identified differentiation in cranial musculature linked to distinct ecological strategies.
Head size significantly contributed to variations in muscle architecture.
Noted that ecological context imposes functional constraints on the muscular organization of the feeding system.
