Exon-based phylogenomics strengthens the phylogeny of Neotropical cichlids and identifies remaining conflicting clades (Cichliformes: Cichlidae: Cichlinae)

摘要

Graphical abstractDisplay OmittedHighlights?415 exons captured for 139 species of predominantly Neotropical cichlids.?Long-established interrelationships of major lineages supported.?Relationships among Geophagini clades clarified by species tree analyses.?Conflicting relationships among caquetaines, amphilophines, and herichthyines.AbstractThe phenotypic, geographic, and species diversity of cichlid fishes have made them a group of great interest for studying evolutionary processes. Here we present a targeted-exon next-generation sequencing approach for investigating the evolutionary relationships of cichli
