FIGURE 2. Principal Components Analysis. Males. Bidimensional plot of the specimens scores. Triangle: BABIA (Northern slopes of Sierra de Villabandín; NML-II haplotype). Inverted triangles: SALIENTES (Nevadin-Tambarón-Catoute populations; NML-I haplotype). Crosses: TIENDAS & SUSPIRON (Sierra de las Tiendas and Suspiron peak; NML-II haplotype). Blades: VILLABANDIN (Sierra de Villabandín or La Cañada; NML-II haplotype). Despite to be significant, the two first axes had a very poor discriminative power, with only a 33.8 % of variance explained (see text for details) and show a considerable overlap of the NML-I specimens that are distributed overlapping with the main part of the other samples. The second axis seems to have a geo-climatic interpretation, separating in the positive part the most northern (oceanic influenced) samples (BABIA) and in the negative part the ones inhabiting the more continental and harsh climate areas facing to the Spanish Northern Plateau (Meseta) (VILLABANDIN -Southern slopes of the same Sierra de Villabandin-), BAYOS, TIENDAS and SUSPIRON. Note that BABIA (triangle symbol) specimens are geographical neighbors (in the northern slopes) of VILLABANDIN (blades symbol) (in the southern slopes), but appear totally opposite in the PCA, in accord with this bioclimatic influence in the scalation. These more continental climate populations show the greater values for most scalation characteristics and the smaller ones for Tympanic plate size.
