Methodology
  • Inputs were obtained with a ddRAD library processed with the software ipyrad. Evolutionary relationships were estimated under two approaches. A maximum likelihood (ML) estimate was obtained from RAxML v. 8.2.8 (Stamatakis, 2014) and coalescent-based approach was also used to estimate phylogenetic relationships using the program SVDquartets (Chifman and Kubatko, 2014) as implemented in PAUP* 4.0 (Swofford, 2003). Two phylogenetic trees were estimated with SVDquartets: one for the phylogenetic relationships estimated among individuals, and another for species lineages. Support was assessed with 1,000 bootstrap replicates in all reconstructions. To infer the position of the root in Phalloceros, we extracted the SNPs from the aligned reference genome and reconstructed the phylogenetic relationships among individuals using unlinked SNPs with SVDquartets setting Xiphophorus maculatus as outgroup. Maximum likelihood ancestral state reconstructions were performed in the package ape in R with the pruned RAxML tree. *For further information consult the manuscript.
Description
  • Estimated phylogenetic relationships based on more than 18,000 loci in 93 individuals (full data) or 21 individuals (subset data) representing 19 described species and two putative undescribed species. Nine files are part of this dataset, including all input files to infer the phylogenetic reconstructions and the outputs obtained, in addition to a pruned tree used to infer the ancestral state reconstructions.

Key Points:
- ddRAD data input files used to reconstruct the phylogenetic relationships in Phalloceros
- phylogenetic reconstructions in Phalloceros

Research Overview:
Estimated phylogenetic relationships based on more than 18,000 loci
in 93 individuals (full data) or 21 individuals (subset data)
representing 19 described species and two putative undescribed species.

Methodology:
Inputs were obtained with a ddRAD library processed with the software ipyrad (Eaton, 2014).
Specimens identification and voucher numbers are available in all files.
Further information about specimens is available in the Supplementary Material of the manuscript.

Evolutionary relationships were estimated under two approaches. A maximum likelihood (ML) estimate
was obtained from RAxML v. 8.2.8 (Stamatakis, 2014) and coalescent-based approach was also used to
estimate phylogenetic relationships using the program SVDquartets (Chifman and Kubatko, 2014) as implemented
in PAUP* 4.0 (Swofford, 2003). Two phylogenetic trees were estimated with SVDquartets: one for the phylogenetic
relationships estimated among individuals, and another for species lineages. Support was assessed with 1,000
bootstrap replicates in all reconstructions.

To infer the position of the root in Phalloceros, we extracted the SNPs from the aligned reference genome and
reconstructed the phylogenetic relationships among individuals using unlinked SNPs with SVDquartets setting
Xiphophorus maculatus as outgroup.

Maximum likelihood ancestral state reconstructions were performed in the package ape in R with the pruned RAxML tree.
