Figure 1. Geographical distribution of Ctenomys magellanicus sampling sites along the study area. Squares show the two regions: north (steppe, chromosome form 2n = 34) and south (ecotone, chromosome form 2n = 36). Each region was subdivided into subpopulations: two for the north (subpopulations A and B) and four for the south (subpopulations C–F).

Figure 3 in Integrative lineage delimitation in rodents of the Ctenomys Corrientes group
Figure 3: Phylogeny based on the complete cyt-b sequence of 138 Octodontid taxa. Nodes with Bayesian posterior probability value <0.7 were collapsed into polytomies. Diploid (2n) and fundamental (FN) numbers are shown next to each terminal, based on data published by Argüelles et al. (2001), Tomasco and Lessa (2007), Caraballo et al. (2015) and references therein.
Figure 2 in Integrative lineage delimitation in rodents of the Ctenomys Corrientes group
Figure 2: Map showing Correntinean populations (black dots) studied by cytogenetics, mtDNA phylogeny and SSR clustering. Numbered black dots correspond to the following localities: 1-Arroyo Pehuajó, 2-Costa Mansión, 3-Estancia San Luis, 4-Mburucuyá, 5-Manantiales, 6-Loma Alta, 7-Pago Alegre, 8-Rincón de Ambrosio, 9-Colonia 3 de Abril, 10-Saladas Sur, 11-Saladas Centro, 12-Saladas Norte, 13-San Roque, 14-Goya, 15-Chavarría, 16-Paraje Sarandicito, 17-Mbarigüí, 18-Paraje Angostura, 19-San Alonso, 20-Paraje Caimán, 21-Loreto, 22-Curuzú Laurel, 23-San Miguel, 24-Santa Rosa, 25-Estancia la Tacuarita, 26-Contreras Cué. The extent of occurrency of the seven Correntinean lineages delimited in this paper was drawn according to the IUCN Red List Categories and Criteria (Anonymous 2012). We used different colors for depicting lineages: Ctenomys roigi (green), C. dorbignyi (blue), C. perrensi complex (red), Sarandicito (orange), Iberá i (pink), Iberá ii (light purple), Iberá iii (violet).

Sampling localities are listed according to the order of the photographs (beginning from the upper left, in left-right direction, ending in the lower right): Loreto, Loreto (another specimen from the same population as preceding one), Manantiales, Mburucuyá, Pago Alegre, Santa Rosa, Saladas Centro, Saladas Sur, Estancia San Luis and Sarandicito.

Figure 5 in Intra- and interspecific skull variation in two sister species of the subterranean rodent genus Ctenomys (Rodentia, Ctenomyidae): coupling geometric morphometrics and chromosomal polymorphism
Figure 5. Shape differences in the skulls of Ctenomys torquatus and Ctenomys pearsoni: columns correspond to dorsal, ventral, and lateral views, respectively. The first row corresponds to the intersexual patterns of shape variation between male (grey lines) and female (dark lines) specimens. The second row represents interspecific patterns of shape variation between C. torquatus (dark lines) and C. pearsoni (grey lines). The third and fourth rows correspond to intraspecific differences between populations of C. torquatus with 2n = 44 from Brazil (grey lines) and from Uruguay (44u) (dark lines), and populations of C. pearsoni with 2n = 70 (dark lines) and 2n = 66 (grey lines), respectively. The shape differences are amplified ¥ 2.

Figure 3. A in Historical demography and spatial genetic structure of the subterranean rodent Ctenomys magellanicus in Tierra del Fuego (Argentina)
Figure 3. A, minimum spanning tree of nine mtDNA haplotypes of Ctenomys magellanicus from Tierra del Fuego, Argentina. Areas are proportional to haplotype frequencies, shading indicates populations, and cross hatches represent nucleotide differences between haplotypes. Haplotype numbers correspond to those of Table 1. Abbreviations for populations are given in Figure 1. B, observed and expected mismatch distributions for C. magellanicus (south + north). Dashed line, observed distribution; solid line, theoretical expected distribution under a population expansion model.
