Sex-biased dorsal spotted patterns in the fire salamander (Salamandra salamandra)
Original language description
Sexual dichromatism has been reported for several amphibian species. Generally, in the animal kingdom, males are more colourful than females. This more pronounced colouration in either quantitative (area of pigmentation) or qualitative (hue, saturation,brightness) form probably plays a role in courtship or mate attraction, but one common polytypic species Salamandra salamandra is still unexplored in this conjunction. We investigated the dorsal patterns of wintering salamanders captured from December 2012 to April 2013 in six underground shelters in Slovakia. We recorded significant size differences between the sexes in all of the morphometric characteristics evaluated, and using free image analysis software, we provide first evidence of the existenceof sexual dichromatism in this species, as males exhibit significantly larger yellow spots on the dorsum and tail than females. No significant sex-related differences in the number of spots and their qualitative colour parameters (hue, sa
