Abstract: The interplay among evolutionary mechanisms like gene flow and selection may result in discordant signals between mitochondrial DNA, nuclear markers and phenotypes. The Andean hummingbirds Coeligena bonapartei and Coeligena helianthea showed differentiation in the gene… read more here.

DOI: 10.1098/rsbl.2021.0190
Abstract: Hummingbirds are perhaps the most exquisite bird species because of their prominent iridescence, created by stacks of melanosomes in the feather barbules. The feather colours crucially depend on the nanoscopic dimensions of the melanosome, and… read more here.
