Digit ratio in the common toad Bufo bufo: the effects of reduced fingers and of age dependency

Popis výsledku v původním jazyce

Introduction Despite the growing number of studies describing digit ratio patterns in tetrapods, knowledge concerning certain basic issues is still scarce. In lower vertebrates such as tailless amphibians Anura, the numbering of individual fingers on the forelimbs and their homology with the fingers of other vertebrates pose an unsolved problem. Based on reviewed data on anuran limb development, we argue that the correct finger numbering scheme should be based on the assumption that the first finger, not the fifth finger, was reduced on the forelimbs. We analyzed the digit ratio in the common toad Bufo bufo, Bufonidae, a species characterized by well developed sexual dimorphism whereby females are larger than males, using both numbering schemes present in the literature. Results We found that the digit ratio on hindlimbs differed significantly between the sexes only in the cases of left 2D 3D, with lower digit ratios in females, and of left 3D 4D, with lower digit ratios in males. We found that sex w
