Evolutionary dynamics of a South American flycatcher

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.
