Implications for evolutionary trends from the pairing frequencies among golden-winged and blue-winged warblers and their hybrids

John Confer, Cody Porter, Kyle Aldinger, Ronald Canterbury, Jeffery Larkin & Darin McNeil
Extensive range loss for the Golden-winged Warbler (Vermivora chrysoptera) has occurred in areas of intrusion by the Blue-winged Warbler (V. cyanoptera) potentially related to their close genetic relationship. We compiled data on social pairing from nine studies for 2,679 resident Vermivora to assess evolutionary divergence. Hybridization between pure phenotypes occurred with 1.2% of resident males for sympatric populations. Pairing success rates for Golden-winged Warblers was 83% and for Blue-winged Warblers was 77%. Pairing success for...

Finding complexity in complexes: assessing the causes of mitonuclear discordance in a problematic species complex of Mesoamerican toads

Thomas Firneno, Justin O'Neill, Daniel Portik, Alyson Emery, Josiah Townsend & Matthew Fujita
Mitonuclear discordance is a frequently encountered pattern in phylogeographic studies and occurs when mitochondrial and nuclear DNA display conflicting signals. Discordance among these genetic markers can be caused by several factors including confounded taxonomies, gene flow, and incomplete lineage sorting. In this study, we present a strong case of mitonuclear discordance in a species complex of toads (Bufonidae: Incilius coccifer complex) found in the Chortís Block of Central America. To determine the cause of mitonuclear...

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...

Golden-winged Warbler post-fledging movement and stand-scale habitat selection

Cameron Fiss, Darin McNeil, Amanda Rodewald, Joseph Duchamp & Jeffery Larkin
Our understanding of songbird habitat needs during the breeding season stems largely from studies of nest success. However, growing evidence shows that nesting habitat and post-fledging habitat often differ. Management guidelines for declining species need to be revaluated and updated to account for habitat shifts that may occur across the full breeding cycle. The Golden-winged Warbler (Vermivora chrysoptera) is a declining songbird species for which best management practices (BMPs) are based overwhelmingly on nesting habitat....
