Sampling sites of Galician (NW Spain) L. saxatilis.
Table 2.
Mean (±SD) of the significant variables derived from the geometric morphometrics analyses.
Results are given for each morphotype and locality, including the results from both the randomization (ignoring the origin of the localities) and the nested (including the geographical origin) ANOVAS, indicating the existence of significant differences among morphotypes.
Fig 1.
Geometric morphometrics analysis.
a) Individuals from different ecotypes (SRB, RB and SU) and localities plotted for size (CS) and the relative shell aperture (RW1) of shell shape. b) Photo and corresponding thin-plate spline representation of the geometric deformations explained by RW1 for the three ecotypes (SRB, RB and SU). Percentages correspond to aperture size values.

Phylogenetic relationships among Galician snails.
(a) Phylogram of Galician L. saxatilis. Numbers above branches indicate bootstrap node support in RAxML/Bayesian posterior probability in MrBAYES. Only bootstrap values and posterior probabilities of, respectively, 60% and 0.7 or greater are depicted. (b) Location of sampling sites. (c) Statistical parsimony network. Pie charts represent the frequencies at each locality. Each white circle represents a mutational step. Note that clade I specimens from Tapia are clustered together with Arealonga clade I specimens in the same pie chart. In all panels, colour and symbol designation indicates geographic origin.
