Teleogramma ddRAD-Seq raw sequence reads

The lower Congo River (LCR) is a freshwater biodiversity hotspot in Africa characterized by some of the world's largest rapids. However, little is known about the evolutionary forces shaping this diversity, which include numerous endemic fishes. We investigated phylogeographic relationships in Teleogramma, a small clade of rheophilic cichlids, in the context of regional geography and hydrology. Previous studies have been unable to resolve phylogenetic relationships within Teleogramma due to lack of variation in nuclear genes and discrete morphological characters among putative species. To sample more broadly across the genome we analyzed double-digest restriction-associated sequencing (ddRAD) data from 53 individuals across all described species in the genus.
