Figure 1 in Resolving the taxonomic status of Ctenomys paramilloensis (Rodentia, Ctenomyidae), an Andean nominal form from Mendoza Province, Argentina
Figure 1: Map of Mendoza province (A–B) and study area (red square in B; C) showing the distribution of the new samples (black squares; B–C) of C. mendocinus obtained in this study and previous Ctenomys records (white circles; B) recovered within C. mendocinus clade. Numbers (B–C) correspond to terminals of C. mendocinus clade in Figure 3. Elevation gradient is represented in the bottom panel.
Figure 3 in Resolving the taxonomic status of Ctenomys paramilloensis (Rodentia, Ctenomyidae), an Andean nominal form from Mendoza Province, Argentina
Figure 3: Phylogenetic placement of Ctenomys specimen from the Sierra de Uspallata (indicated in bold) based on the 50 % majority-rule consensus tree from BI analyses. Black circles denote nodes that are strongly supported by both BI and ML analyses; gray circles indicate nodes that are moderately supported by either BI or ML (threshold values indicated).

FIGURE 3 in The population of Ctenomys from the Ñacuñán Biosphere Reserve (Mendoza, Argentina) belongs to Ctenomys mendocinus Philippi, 1869 (Rodentia: Ctenomyidae): molecular and karyotypic evidence
FIGURE 3. Phylogenetic tree resulting from the Bayesian analysis of the cyt-b gene sequences of Ctenomys. The outgroup is not shown. Numbers indicate support (Bootstrap [only those above 50 % are shown], Bremer support, and Posterior probabilities) of the nodes at their right (see details in text). For those sequences retrieved from GenBank, accession numbers are provided next to species labels. For those sequences gathered by us, specimen collection numbers are provided next to species label.
