Figure 5 in Genetic, bioacoustic and morphological analyses reveal cryptic speciation in the warbling vireo complex (Vireo gilvus: Vireonidae: Passeriformes)
Figure 5. Example song spectrograms and photos for each of the three warbling vireo genetic groups used in our DFA of songs. The colours of the outlines of the spectrograms and photos correspond to DFA results in Figure 4. Photos were taken by the first author.
Figure 4 in Genetic, bioacoustic and morphological analyses reveal cryptic speciation in the warbling vireo complex (Vireo gilvus: Vireonidae: Passeriformes)
Figure 4. Plots of the first two canonical axes based on DFA of warbling vireo songs. Colours and shapes correspond to three of the four microsatellite genetic groups (Black Hills are not included): eastern (red/circle), north-western (green/ square) and south-western (blue/triangle). The largest shape represents the mean centroid for each genetic group.
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.
Relationships of song structure to phylogenetic history, habitat, and morphology in the vireos, greenlets, and allies (Passeriformes: Vireonidae)
<p>Acoustic signals show immense variation among passerines, and several hypotheses have been proposed to explain this diversity. In this study, we tested, for the first time, the relationships of song structure to phylogeny, habitat type, and morphology in the vireos and allies (Vireonidae). Every measure of song structure considered in this study had moderate and significant phylogenetic signal. Furthermore, two song-constraining morphological traits, bill shape and body mass, also exhibited significant phylogenetic signal. Song length showed the largest within-clade similarity; longer songs were highly conserved in part of the greenlet (<i>Hylophilus</i>) clade, whereas shorter songs characterized the remaining seven genera. We found no differences in song structure among vireonids living in different habitat types. However, vireonids with shorter, stouter bills and larger bodies sang songs with lower minimum and maximum peak frequency, compared with species with longer, thinner bills and smaller bodies. We conclude that Vireonidae song evolution is driven partially by phylogenetically conserved morphological traits. Our findings support the phylogenetic signal and morphological constraints hypotheses explaining structural diversity in avian acoustic signals.</p>
