Reconstructing the cranial evolution of the salamander using geometric morphometric data from 148 species, we demonstrate that life cycle influences cranial shape diversity and rate of evolution.
Geometric morphometric data from 148 salamander species collected from high-resolution 3D scans.
Segmented crania of 40 individual Italian Fire Salamanders (Salamandra salamandra gigliolii), reconstructed from micro CT scans.
Applying a high-dimensional geometric morphometric approach, we show that size has no significant effect on cranial shape in the Italian fire salamander (Salamandra salamandra giglioli).
