Calibrating the molecular clock beyond cytochrome b: assessing the evolutionary rate of COI in birds
Pablo D. Lavinia, Auteur ; Kevin C. R. Kerr, Auteur ; Pablo L. Tubaro, Auteur ; Paul D. N. Hebert, Auteur ; Dario A. Lijtmaer, AuteurEstimating the age of species or their component lineages based on sequence data is crucial for many studies in avian evolutionary biology. Although calibrations of the molecular clock in birds have been performed almost exclusively using cytoch[...]

Arild Johnsen, Auteur ; Eirik Rindal, Auteur ; Per G. P. Ericson, Auteur ; Dario Zuccon, Auteur ; Kevin C. R. Kerr, Auteur ; Mark Y. Stoeckle, Auteur ; Jan T. Lifjeld, AuteurBirds are a taxonomically well-described group of animals, yet DNA barcoding, i.e., the molecular characterization of species using a standardized genetic marker, has revealed unexpected patterns of genetic divergences among North American birds[...]
Article
Kevin C. R. Kerr, Auteur ; Alison Cloutier, Auteur ; Allan J. Baker, AuteurThe functional constraint imposed on exonic sequences increases marker universality and improves sequence alignment accuracy, yet introns have been favoured recently in Avian Tree of Life studies because of the increased sequence coverage that w[...]

Erin L. Heller, Auteur ; Kevin C. R. Kerr, Auteur ; Nor F. Dahlan, Auteur ; Carla J. Dove, Auteur ; Eric L. Walters, AuteurFlycatchers in the genus Empidonax are among the most difficult avian taxonomic groups to identify to species. Observers often rely on calls or songs in the field or detailed morphometrics in the hand to identify species. In January and February[...]
