Hypothesis
How does the allometry of limb bones in felids vary with size and function?
Conclusion
Bone allometry in felids is influenced by regional variations in bone function, allowing for adaptation during evolutionary changes.
Supporting Evidence
- Scaling exponents for midshaft parameters were generally greater than isometry.
- Allometry was highly variable and related to local bone function.
- Joint surfaces and muscle attachment sites showed stronger positive allometry than the midshaft.
Takeaway
This study looked at cat bones in 3D to see how their shapes change with size, showing that different parts of the bones grow differently based on their jobs.
Methodology
Computed tomographic images were taken of limb bones from 13 individuals of 9 feline species, and various geometric parameters were calculated.
Limitations
Body masses for museum specimens were not available, which may affect scaling calculations.
Participant Demographics
9 feline species ranging from domestic cats to tigers.
