Fig. 1 in Unearthing the species diversity of a cryptozoic snake, Tantilla melanocephala, in its northern distribution with emphasis on the colonization of the Lesser Antilles

Fig. 1. (A) Tantilla melanocephala sample localities for this study (red circles) in the northern region of its distribution. (B) The distribution of Tantilla melanocephala in the Neotropics. Locality data are from VertNet and the GBIF databases, as well as the literature (Nogueira et al. 2019). Within the Lesser Antilles, Union Island and the Mustique islands are not shown. Red circles are T. melanocephala localities included in the phylogenetic analyses. The map suggests this species inhabits several different biomes.

Red and black nodes are posterior probabilities (1.00 and> 95–99%), respectively. Photo by J.C. Murphy.

Fig. 3 in First records of prevalence and diversity of avian haemosporidia in snipe species (genus Gallinago) of Japan

Fig. 3. Bayesian phylogenetic analysis of cytb gene lineages (470 bp) of avian haemosporidian parasites, rooted with Theileria annulata. Posterior clade probabilities of>0.60 were indicated. The branch lengths are drawn proportionally to the amount of change according to the substitution model applied. Lineages derived in this study are shown in red letters. Major clades (A–C) containing derived lineages are shown. The host order is shown to the right of the lineage name, according to the provided legend. (For interpretation of the references to colour in this figure legend, the reader is referred to the Web version of this article.)
