1.We examined intra- and interspecific variation in functional morphology and whole-organism performance in a sympatric lizard species pair, Iberolacerta horvathi and Podarcis muralis, in the area with a high potential for competition.
2.The biggest variation between species was found in two functional traits, bite force and climbing speed, linked with corresponding morphological traits.
3.The species with larger and taller heads, P. muralis, exhibited correspondingly stronger bite forces. The other species exhibited smaller and flatter head.(...)
