Figure 3 in Genetic, bioacoustic and morphological analyses reveal cryptic speciation in the warbling vireo complex (Vireo gilvus: Vireonidae: Passeriformes)
Figure 3. Thirty-seven warbling vireo populations genotyped at 14 microsatellite loci. Colours correspond to the four genetic groups from STRUCTURE: eastern (red), north-western (green), south-western (blue) and the Black Hills (orange) (see Fig. 2). The eastern (Medicine Hat, M HAT; left circle) and north-western (Cypress Hills, C HILLS; right circle) groups from the SEAB population are shown separately. Refer to Table 1 for population abbreviations and sample sizes.
Figure 2 in Genetic, bioacoustic and morphological analyses reveal cryptic speciation in the warbling vireo complex (Vireo gilvus: Vireonidae: Passeriformes)
Figure 2. Hierarchical STRUCTURE plots (K = 2) based on genotypes from 14 microsatellite loci. Populations with additional hierarchical structure are in yellow. Each bar represents a single individual, and the Q value is the percent ancestry of that individual to each genetic group. (A) All populations (red = eastern group), (B) western populations and the Black Hills (orange), (C) remaining western populations (north-western = green; south-western = blue). Refer to Table 1 for population abbreviations and sample sizes.
Figure 1 in Genetic, bioacoustic and morphological analyses reveal cryptic speciation in the warbling vireo complex (Vireo gilvus: Vireonidae: Passeriformes)
Figure 1. Range distributions of the three warbling vireo subspecies in this study based on Phillips (1991) and American Ornithologists' Union (1998) in gray scale on the map. Circles on the map show sampling locations included in the cyt b analysis (top inset). Black circles are eastern haplotypes, whereas white circles are western haplotypes. The eastern (Medicine Hat, M HAT; left circle) and western (Cypress Hills, C HILLS; right circle) groups from the SEAB population are shown separately. The ATPase 6 and 8 results are not on the map (bottom inset) and do not include the eastern group. Colours in the haplotype networks correspond to our microsatellite genetic groups: eastern (black), north-western (grey), south-western (white) and the Black Hills (striped). Each circle is a haplotype, and its size is proportional to how many individuals share that haplotype. Cross hatches in the haplotype networks represent more than one nucleotide difference. Refer to Table 1 for population abbreviations and sample sizes.
Figure 6 in Genetic, bioacoustic and morphological analyses reveal cryptic speciation in the warbling vireo complex (Vireo gilvus: Vireonidae: Passeriformes)
Figure 6. Contemporary ecological niche models for three of the four warbling vireo microsatellite genetic groups (Black Hills are not included): north-western (top), south-western (middle) and eastern (bottom). The logarithmic scale on the left depicts the percent likelihood of habitat suitability based on climate variables.

FIGURE 1 in Cryptic speciation: distinguishing serpentine affiliated sister species Navarretia paradoxiclara and N. paradoxinota from N. intertexta (Polemoniaceae)
FIGURE 1. Representative most parsimonious phylograms inferred from analysis of DNA sequence data. Acronyms following species names are correlated to specimens in Appendix 1. Lower case letters ('a' and 'b') following acronyms in Figs. 1B, C indicate multiple copies indicative of either polyploidy (e.g. N. propinqua) or possibly gene duplication or intrapopulation variation among multiple individuals (e.g. N. leucocephala). Total character change (base substitutions and indels) are reconstructed above interior branches (terminal values can be inferred by branch length). Branches not found in all shortest trees are indicated by dotted lines. Bootstrap support values are shown in bold italics below branches. A. One of six trees inferred from concatenated cpDNA sequences. B. One of 32 trees inferred from nrDNA ITS sequences. C. One of six trees inferred from nuclear PI sequences.
