Incipient speciation and secondary contact in a fossorial island endemic, the São Tomé caecilian

Kyle O'Connell, Ivan Prates, Lauren Scheinberg, Kevin Mulder & Rayna Bell
Secondary contact of lineages in the early stages of divergence can result in lineage fusion or promote reproductive isolation through reinforcement. While these processes are well studied in many taxonomic groups, we know little about their contribution to diversification of the secretive and enigmatic caecilians (Amphibia: Gymnophiona). Here, we combine genetic (mtDNA and genome-wide SNPs) and phenotypic data to investigate the divergence history of caecilians endemic to the oceanic island of São Tomé in the...
