Phylogenomics of African <em>Labeo</em> (Cypriniformes: Cyprinidae) emphasizing central African species

Here we present the first large-scale phylogenomic analysis of the genus Labeo using 2,187 ultraconserved elements (UCEs) from 85 taxa, including 56 recognized species, 27 cryptic (candidate) species, and outgroups from the Asian Labeonini. Concatenated and coalescence-based phylogenetic analyses both strongly support the monophyly of African Labeo and recover three main clades (designated here as subgenera) comprising at least nine species groups. Libraries for the entire dataset were sent to and prepared by RAPiD Genomics (healthcare.rapid-genomics.c…) using the set of 6,737 baits developed by Faircloth et al. (2020) to target 2,708 UCE loci. Sequencing of the captured UCEs also was performed by RAPiD Genomics on an Illumina Hiseq 2500 platform. # Phylogenomics of African *Labeo* (Cypriniformes: Cyprinidae) emphasizing central African species [doi.org](doi.org) ## Description of the data and file structure ### Files and variables #### File: Supplementary_Materials_R2 **Description:** We submitted a compressed folder (Supplementary_materials_R2.zip) containing the following folders and files: * Appendix 1: contains tree files and trip identification * 99_specimens: list of six alternative Maximum likelihood (ML) and Astrall tree files (.tre) based on the dataset with 99 tips and different percentage of matrix completeness (75, 85, and 90 %) * Astral_tree_75percent_50collapse.tre * Astral_tree_85percent_50collapse.tre * Astral_tree_90percent_50collapse.tre * ML_tree_75percent.tre * ML_tree_85percent.tre * ML_tree_90percent.tre * 184_specimens: list of two ML alternative tree files (.tre) based on based on the dataset with 184 tips and a sheadsheet (.xlsx) with tips identification. * ML_tree_75percent.tre * ML_tree_90percent.tre * Tips_identifacation.xlsx * Appendix 2: UCE alignments files and R scripts used to run phylogenetic analyses using both concatenated (ML) and coalescent-based approaches: * Coalescent_R_Script.R * ML_R_Script.R * 184_specimens: dataset with 184 specimens * best_models_scheme_75_ML.nex * best_models_scheme_90_ML.nex * uces_alignment_fasta_files_75_percent_matrix: list of 1,589 UCE alignments in the 75 % complete matrix * uce-0.nexus.fasta * uce-3.nexus.fasta * uce-5.nexus.fasta * uce-6.nexus.fasta * uce-9.nexus.fasta * uce-14.nexus.fasta * uce-15.nexus.fasta * etc * uces_alignment_fasta_files_90_percent_matrix: list of 185 UCE alignments in the 90 % complete matrix * uce-3.nexus.fasta * uce-14.nexus.fasta * uce-15.nexus.fasta * uce-40.nexus.fasta * uce-41.nexus.fasta * uce-43.nexus.fasta * uce-46.nexus.fasta * etc * 99_specimens: dataset with 99 specimens * best_models_scheme_70_coalescent.txt * best_models_scheme_70_ML.nex * best_models_scheme_75_coalescent.txt * best_models_scheme_75_ML.nex * best_models_scheme_85_coalescent.txt * best_models_scheme_85_ML.nex * best_models_scheme_90_coalescent.txt * best_models_scheme_90_ML.nex * uces_alignment_fasta_files_70_percent_matrix: list of 2 187 UCE alignments in the 70 % complete matrix * uce-0.nexus.fasta * uce-2.nexus.fasta * uce-3.nexus.fasta * uce-5.nexus.fasta * uce-6.nexus.fasta * uce-9.nexus.fasta * uce-10.nexus.fasta * etc * uces_alignment_fasta_files_75_percent_matrix: list of 2 090 UCE alignments in the 75 % complete matrix * uce-0.nexus.fasta * uce-3.nexus.fasta * uce-5.nexus.fasta * uce-6.nexus.fasta * uce-9.nexus.fasta * etc * uces_alignment_fasta_files_85_percent_matrix: list of 1 441 UCE alignments in the 85 % complete matrix * uce-0.nexus.fasta * uce-3.nexus.fasta * uce-5.nexus.fasta * uce-14.nexus.fasta * uce-15.nexus.fasta * etc * uces_alignment_fasta_files_90_percent_matrix: list of 739 UCE alignments in the 90 % complete matrix * uce-3.nexus.fasta * uce-14.nexus.fasta * uce-15.nexus.fasta * uce-21.nexus.fasta * uce-28.nexus.fasta * etc * Appendix 3: contains files used in ancestral range reconstruction.
