Delimitation despite discordance: Evaluating the species limits of a confounding species complex in the face of mitonuclear discordance

Thomas Firneno, Justin O'Neill, Michael Itgen, Timothy Kihneman, Josiah Townsend & Matthew Fujita
The delimitation of species is an essential pursuit of biology, and proper taxonomies are crucial for the assessment and conservation management of organismal diversity. However, delimiting species can be hindered by a number of factors including highly conserved morphologies (e.g. cryptic species), differences in criteria of species concepts, and discordance between gene topologies (e.g. mitonuclear discordance). Here we use a taxonomically confounded species complex of toads in Central America that exhibits extensive mitonuclear discordance to...
