Genetic structure of the 44 <i>Calotriton asper</i> populations.

<p>Genetic structure of the 44 <i>Calotriton asper</i> populations. A) Results of Bayesian clustering and individual assignment analysis obtained with STRUCTURE at <i>K</i> = 2 including all <i>Calotriton asper</i> populations (above), the western Pyrenean populations with <i>K</i> = 2 and the central-eastern Pyrenean populations with <i>K</i> = 3. Each individual is represented by a thin bar corresponding to the sum of assignment probabilities to the <i>K</i> cluster. Black bars separate populations. B) Map of the five genetic clusters.
