The Fondon Lab teams up with researchers at the University of Utah and pigeon fanciers across the nation to uncover the genetic basis of plumage color variation in domestic pigeons. Leveraging knowledge about the genetic basis of color variation in other species, Shreyas Krishnan and Clifford Rodgers, students in the Fondon Lab, identified mutations in three genes responsible for four different color traits, finding that some color variants evolved repeatedly through recurrent mutations in the same genes.
Dr. Matthew Fujita was part of a collaborative team to uncover interesting dynamics that have influenced the evolution of Zimmerius flycatchers in an article published in Systematic Biology. A “mosaic” population has acoustic and biometric similarities to a souther species, Z. viridiflavus, but plumage characteristics of a northern species, Z. chrysops. Using RADseq, they discovered that the mosaic population is largely allied with Z. viridiflavus. However, low levels of introgression from chrysops into the mosaic population was detected that may have influenced the plumage affinity between the two lineages.
Dr. Todd Castoe leads an international team on the genome sequencing of the Burmese python (Python molurus). Read the publication in Proceedings of the National Academy of Sciences. This paper was published alongside the genome sequence of the king cobra.
Dr. Todd Castoe and Dr. Matt Fujita are featured in the Fort Worth Star Telegram regarding the publication of the painted turtle (Chrysemys picta) genome. Jill Castoe is also featured, advocating the capabilities of the Genomics Core Facility.
Congratulations to Alex Hall, Kyle O'Connell, and Daren Card for securing prestigious research awards this year. Alex and Daren were awarded the Rosemary Grant Research Award from the Society for the Study of Evolution, and Kyle recieved the Roosevelt Grant from the American Museum of Natural History to conduct field work in the southeast U.S. for coachwhip snakes.
