Figure 1. From top to bottom and right to left: location of
sampling populations, theoretical straight-line dispersal route
following valley bottoms between them, altitude profile of this route,
and the position of both populations and dispersal route (means and SDs)
in an environmental gradient described in detail elsewhere
(Llanos-Garrido et al.2021). These environmental changes are based on an
environmental PCA that summarizes BIOCLIM variables on temperature and
humidity across all the species’ range (annual mean temperature, maximum
temperature of the warmest month, mean temperature of the warmest
quarter, and annual precipitation).
Figure 2. Size differences between males with sexual
ornamentation and those without it in Navacerrada (mean ± IC95).
Figure 3. Probability of assignment to groups generated by
Admixture for the model with two groups (K=2). On the left, CV-errors
for each of the models analyzed; the most credible model is the one that
includes only one group (K=1).
