Figure 2. A, Tree resulting from maximum likelihood analysis from the 12S in A molecular perspective on the evolutionary affinities of an enigmatic neotropical frog, Allophryne ruthveni

Figure 2. A, Tree resulting from maximum likelihood analysis from the 12S data set using the Hasegawa–Kishino–Yano two parameter model (Hasegawa et al., 1985). Included for comparative purposes are bootstrap support from NJ analyses. Below each resolved branch are indicated percentage bootstrap support in excess of 50% for: ML (100 pseudoreplicates), NJ (1000 pseudoreplicates; Kimura 2-parameter), NJ (1000 pseudoreplicates; Tamura–Nei). B, Strict consensus of three most parsimonious trees (all substitutions weighted equally; tree length = 164 steps). Below each branch are indicated percentage bootstrap support (1000 pseudreplicates) in excess of 50% for: MP (unweighted), MP (stems weighted twice loops), MP (transversions weighted four times transitions). Bremer decay indices (DI) are the final value shown below each resolved branch (for MP unweighted only). A dash indicates bootstrap support of less than 50%.

FIGURE 5. 12S in A systematic revision of Draculoides (Schizomida: Hubbardiidae) of the Pilbara, Western Australia, Part I: the Western Pilbara

FIGURE 5. 12S mini-barcodes for all Draculoides species including the operational taxonomic units used in Abrams et al. (2019). This barcode is the maximally diagnostic 50 bp fragment of DNA. Genetic variation within species is shown using IUPAC Ambiguity Codes. See Methods for details. The position of the mini-barcode is reported relative to a specimen of Draculoides celatus (WAM T98698, GenBank number MG913012). The blue tree on the left groups minibarcodes which are most similar to each other but does not represent an accurate phylogeny. The coloured bases in the figure are those that differ from the consensus reference sequence.

The panels on the left plot the geographical distribution and frequency of haplotypes in the different localities analysed. Localities were labelled according to their ID (see Table 1). The right panels show the haplotype networks, where the dashes on the lines represent mutations, and the black circles represent intermediate variants not found. Principal Chacoan rivers are shown in light-blue labels. Capitalized labels indicate names of Argentinean provinces, and labels with all letters in uppercase refer to neighbouring countries.

FIGURE 1 in A mitochondrial 12S and 16S rRNA phylogeny of critical genera of Phoridae (Diptera) and related families of Aschiza

FIGURE 1. Maximum likelihood tree derived from analysis of concatenated dipteran 12S and 16S mitochondrial DNA sequences (­ln likelihood = 5910.51681, proportion of invariable sites 0.291, gamma shape parameter = 0.480). Taxa as in Table 1. The Hilara maura sequence was assigned as outgroup. The names of suborders, series, families, subfamilies and tribes are also indicated where they are relevant to the discussion in the text. Numbers refer to Bayesian posterior probabilities as percent (top) or percent support in a non­parametric bootstrap analysis by neighbor­joining of maximum likelihood distances (bottom). Where only one number occurs it refers to a Bayesian posterior probability: that branch received less than 50% support in the non­parametric bootstrap analysis. Support values for the branch leading to the Phoridae are in bold.
