SEXUAL AND GEOGRAPHIC VARIATION OF COLOR PATTERNS IN LIOLAEMUS TENUIS (SQUAMATA, LIOLAEMINAE)

We studied sexual and geographic variation of color patterns in the lizard Liolaemus tenuis. We counted the number of scales with different colors in two body regions, in individuals of both sexes, from three groups of populations along a latitudinal range. Color patterns showed sexual and geographi...
