Phylogenomic Analyses Clarify Butterfly Species Within The Genus Speyeria Despite Evidence Of A Recent Adaptive Radiation, Erin Thompson
Phylogenomic Analyses Clarify Butterfly Species Within The Genus Speyeria Despite Evidence Of A Recent Adaptive Radiation, Erin Thompson
University of the Pacific Theses and Dissertations
The North American genus Speyeria is an especially challenging radiation of butterflies due to ongoing hybridization, incomplete lineage sorting, and similar morphological characters among species. Adaptive radiations often require considerable evidence in order to resolve the evolutionary relationships of closely related individuals. Previous studies of this genus have found paraphyly among species and have been unable to disentangle these taxa due to a lack of data and/or incomplete sampling of the genus. As a result, the interspecific relationships among Speyeria remain unresolved. In an attempt to achieve phylogenetic resolution of the genus, we conducted population genomic and phylogenomic analyses of …
