FIGURE 1 in An extinct hummingbird species that never was: a cautionary tale about sampling issues in molecular phylogenetics

FIGURE 1. (A) Distributions of Aglaiocercus kingii, A. coelestis, and Taphrolesbia griseiventris (polygons), and geographic provenance of specimens of these species and of the Rogitama hybrid hummingbird included in molecular analyses (dots and star). (B) Phylogenetic relationships among species and populations of Aglaiocercus, Taphrolesbia, the Rogitama hummingbird, and Heliangelus zusii based on sequences of the ND2 gene. Black dots indicate strongly supported nodes (0.95 Bayesian posterior probability,> 80% maximum-likelihood bootstrap). The Rogitama hummingbird and H. zusii have haplotypes closely allied to those of A. kingii from the Eastern Cordillera of Colombia, indicating they are hybrids sharing A. kingii as female parent. Sister taxon, Adelomyia melanogenys, and outgroup Chalcostigma herrani, are not shown. Illustrations courtesy of Lynx Edicions (del Hoyo et al. 2018).

FIGURE 2 in An extinct hummingbird species that never was: a cautionary tale about sampling issues in molecular phylogenetics

FIGURE 2. Correlation between genetic divergence (p and Tamura-Nei distances) based on the small fragment available for Heliangelus zusii (fragment) with divergence in complete sequences (ND2 gene) across 315 hummingbird taxa (McGuire et al. 2014 dataset). Genetic distances were calculated in MEGA6 (Tamura et al. 2013) and all positions with missing data were not considered when calculating pairwise genetic distances. The plot is cropped at 10% p-distance, thus providing a better view of the data spread in the area of low divergence relevant to the H. zusii issue. The correlation between the small fragment available for H. zusii and all the ND2 data is strong, and it is especially tight near the origin: 0% divergence in that small fragment essentially means no (or up to approximately 1%) divergence in the rest of the sequence. This suggests that our observation of identical sequences in H. zusii and A. kingii is not an artifact resulting from the small amount of available sequence data.

FIGURE 8. a) Tail prehensility in subadult Oligosoma salmo sp. nov. (61 mm snout-vent; 4.05 g) (photo: Sabine Bernert). This has been observed in many individuals of this species - all those with intact or largely intact tails which have been tested. The grip of the tail on the finger was felt as very firm. b) In this individual (subadult male; 67 mm snout-vent, 6.19 g) the strength of the muscle contraction is shown by the formation of longitudinal ridges in the dorsal scales of the tail, which are normally completely smooth (photo: Lynn Adams).
