New paper: Phylogenomics of pike cichlids (Cichlidae: Crenicichla) and the rapid ecological speciati
In this new paper, we assess the pike cichlid phylogeny using Ultraconserved eletments (UCEs) as well as test the relationships and co-ancestry of five closely-related species (i.e., the Uruguay River species flock; URSF). Additionally, we quantify body and pharyngeal jaw shape of the URSF. We found that these species are well-supported genetic clusters, but that the relationships among them remain problematic, likely due to their recent diversification. In contrast, we found
